Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

The present disclosure provides a needle detector mounting bracket, as shown in fig. 1 and 2, which includes a fixed sleeve frame 1 and a split bracket, the fixed sleeve frame 1 and the split bracket being connected to each other by an adjusting locking structure 4 for clamping and fixing a needle detector 9.

The split bracket comprises a fixed bracket part 21 and a spring bracket part 22, wherein the fixed bracket part 21 comprises a vertical plate part 211 and a transverse plate part 212 which are integrally connected with each other, and the vertical plate part 211 is connected with one end of the fixed sleeve frame 1. The spring bracket 22 includes a first elastic piece 221, an elastic bending portion 222, and a second elastic piece 223, wherein the first elastic piece 221 is connected to the transverse plate 212, the second elastic piece 223 is opposite to the vertical plate 211, and one end of the second elastic piece 223, which is not connected to the elastic bending portion 222, is connected to the other end of the fixed sleeve 1. The adjusting and locking structure 4 is disposed between the transverse plate 212 and the fixed frame 1 to fix the fixed frame 1 and the split bracket, and adjust the bending amplitude of the spring bracket 22 to change the angle of the fixed frame 1 relative to the split bracket.

Through the arrangement of the structure, one end of the fixed support part 21 of the mounting support has certain rigidity, and the spring support part 22 has certain elasticity, so that after the needle detector 9 is fixed on the knitting machine by the mounting support, when the needle detector 9 is not aligned with the knitting needle and needs to be finely adjusted, the adjusting and locking structure 4 can be operated, so that part of the spring support part 22 is stressed to bend, the fixed support part 21 cannot deform in the bending process, and at the moment, the fixed support part 1 is driven to deviate to a certain extent, the whole needle detector 9 is driven to deviate to a certain extent, and the needle detector 9 can be aligned with the position of the knitting needle better. In addition, after the split support is arranged into the fixed support part 21 and the split support part, one side of the split support is ensured to meet the rigidity requirement, and the other side of the split support is ensured to meet the elasticity requirement, and meanwhile, after the split support is divided into two parts, the split support is convenient to produce the fixed support part 21 and the spring support part 22, and then the fixed support part 21 and the spring support part are only required to be connected, so that the production cost is greatly reduced.

As shown in fig. 2 and 4, the first elastic piece 221 is attached to the transverse plate 212, and the first elastic piece 221 is connected to the transverse plate 212 by a screw. That is, a screw hole is provided in the cross plate portion 212, and a screw is inserted through the first elastic piece portion 221 and is connected to the inside of the screw hole, so that the first elastic piece portion 221 and the cross plate portion 212 are fixed to each other.

By attaching the first elastic piece portion 221 to the cross plate portion 212 and connecting the first elastic piece portion 221 to the cross plate portion by a screw, the first elastic piece portion and the cross plate portion can be stably connected, and the mounting is relatively convenient, so that the cost for mounting the first elastic piece portion and the cross plate portion is reduced.

In the present embodiment, as shown in fig. 4, four screws are provided between the first elastic piece portion 221 and the cross plate portion 212, and the four screws are distributed at both side edge positions of the cross plate portion 212. Thus, the first spring piece 221 and the cross plate 212 can be further stably fixed.

Further, as shown in fig. 1, the elastic bending portion 222 is U-shaped, and a notch 2221 is formed at a center of the elastic bending portion 222.

By means of the notch 2221, the bending elasticity of the spring support can be reduced, deformation of the spring support can be effectively avoided, and meanwhile a certain weight reduction effect can be achieved.

As shown in fig. 1, the thicknesses of the first elastic piece 221, the elastic bending portion 222, and the second elastic piece 223 are smaller than those of the horizontal plate 212 and the vertical plate 211.

In this way, the rigidity requirement of the fixing bracket portion 21 can be better ensured, and the connection between the following first elastic sheet portion 221 and the transverse plate portion 212 is also facilitated.

In some embodiments, as shown in fig. 4, 7 and 8, an end of the vertical plate portion 211 away from the transverse plate portion 212 and an end of the second elastic piece portion 223 away from the first elastic piece portion 221 are respectively provided with an arc-shaped slot 3, the fixing sleeve frame 1 is U-shaped, two ends of the fixing sleeve frame 1 are integrally connected with a U-shaped sleeve 11, and an opening slot 111 is provided at a connection portion between the U-shaped sleeve 11 and the fixing sleeve frame 1. After the fixing sleeve frame 1 and the split support clamp the knitting needle detector 9, the first elastic piece part 221 and the vertical plate part 211 respectively extend into the opening grooves 111 at the two U-shaped sleeves 11, and the arc-shaped clamping grooves 3 of the first elastic piece part 221 and the vertical plate part 211 respectively abut against the knitting needle detector 9.

Through the setting of this kind of structure, can be convenient for make fixed bolster portion 21 and spring bracket portion 22 carry out stable concatenation with fixed cover frame 1, and make the whole difficult come out that drops of split support, through the setting of arc draw-in groove 3 simultaneously, can more effectually carry out the centre gripping to knitting needle detector 9, be difficult for causing certain scratch to knitting needle detector 9. In addition, after the spring bracket 22 is forced to bend, the arc-shaped clamping groove 3 of the second elastic piece 223 keeps in contact with the knitting needle detector 9, and the vertical plate 211 can slide along the opening groove 111 to a certain extent, so as to ensure that the fixing sleeve frame 1 and the knitting needle detector 9 are offset.

In some embodiments, as shown in fig. 1 and 4, the needle detector mounting bracket further includes a bushing 31, where the bushing 31 includes a first sleeve portion 311 and second sleeve portions 312 connected to two ends of the first sleeve portion 311, the first sleeve portion 311 is embedded inside the fixed sleeve frame 1, two second sleeve portions 312 are respectively embedded inside the two U-shaped sleeves 11, and outer walls of the first sleeve portion 311 and the second sleeve portion 312 are respectively attached to inner walls of the fixed sleeve frame 1 and the U-shaped sleeves 11.

Through this bush 31's setting, can make bush 31 support cover establish to knitting needle detector 9 to make fixed rack 1 not contact with knitting needle detector 9, avoid fixed rack 1 isotructure to cause certain scratch to knitting needle detector 9, can increase the frictional force between knitting needle detector 9 and the fixed rack 1 simultaneously, prevent the slip skew between knitting needle detector 9 and the fixed rack 1.

Further, as shown in fig. 7, the fixed frame 1 is provided with a weight reducing hole 12.

By means of the arrangement of the lightening holes 12, the weight of the fixed sleeve frame 1 can be relatively reduced, and accordingly the weight of the whole mounting bracket is reduced.

In some embodiments, as shown in fig. 4, 5 and 7, the above-mentioned adjusting locking structure 4 includes a locking plate 41 and a locking bolt 42, wherein the locking plate 41 is disposed on the fixed frame 1 and is disposed opposite to the cross plate portion 212, and a threaded hole 411 is disposed on the locking plate 41; through holes are provided in the cross plate portion 212 and the first elastic piece portion 221, through which the locking bolts 42 pass and are connected into the screw holes 411.

With this structure, after the split bracket and the fixing bracket 1 are spliced and the locking bolt 42 is locked into the threaded hole 411 of the locking plate 41, the fixing socket and the split bracket can be stably spliced to form the mounting bracket, and then if the locking bolt 42 is continuously screwed down, the force given by the locking bolt 42 acts on the spring bracket portion 22, so that the spring bracket is forced to bend, the fixing bracket portion 21 is not bent, at this time, the arc-shaped clamping groove 3 of the second elastic piece portion 223 is kept in contact with the knitting needle detector 9, and the vertical plate portion 211 is slid to a certain extent along the opening groove 111 in a direction away from the fixing bracket 1, so that the fixing bracket 1 and the knitting needle detector 9 are biased in a direction away from the fixing bracket portion 21. In contrast, after the locking bolt 42 is unscrewed, the spring support is not stressed and is restored, but the arc-shaped clamping groove 3 of the second elastic sheet portion 223 still keeps abutting against the knitting needle detector 9, and the vertical plate portion 211 is restored to the original position along the opening groove 111 and continuously abuts against the knitting needle detector 9, and at this time, the fixing sleeve frame 1 and the knitting needle detector 9 are restored to the original position.

Further, as shown in fig. 7, the two sides of the fixing frame 1 are respectively provided with a lap hole 13, the width of the lap hole 13 is the same as the width of the locking plate 41, and two ends of the locking plate 41 are respectively overlapped to the two lap holes 13.

In this way, the locking plate 41 can be stably fixed to the fixed housing 1, and the subsequent mounting and dismounting of the locking plate 41 is facilitated.

In addition, the two sides of the fixed sleeve frame 1 are also provided with the placement holes 14, the width of the placement holes 14 is larger than that of the lap joint holes 13, and the placement holes 14 are communicated with the lap joint holes 13.

Thus, when the locking plate 41 is installed, the locking plate 41 can be first inserted into the insertion hole 14 and then moved into the overlap hole 13 for assembly, so that the installation and disassembly efficiency of the locking plate 41 can be effectively improved.

In some embodiments, as shown in fig. 3 and 8, a prompting structure 5 is disposed at the adjusting locking structure 4, and the prompting structure 5 is connected with the adjusting locking structure 4, so that when the adjusting locking structure 4 operates, the prompting structure 5 can be driven to operate to prompt the adjusting locking structure 4 to adjust the amplitude.

After the fixed sleeve frame 1 and the split support are connected by the aid of the prompting structure 5, and the adjusting and locking structure 4 is used for compressing the spring support portion 22 of the split support to enable the knitting needle detector 9 to deflect, when the adjusting and locking structure 4 is enabled to operate at a certain angle, the prompting structure 5 is enabled to generate certain prompting, so that a worker can clearly know the operation amplitude of the adjusting and locking structure 4, and the worker can conveniently, rapidly and accurately adjust the knitting needle detector 9 to a required angle.

In some embodiments, as shown in fig. 3-8, the prompting structure 5 includes a mounting hole 51 and an elastic pressing member 52, where the mounting hole 51 is disposed on the transverse plate 212 and is disposed near the through hole, and a steel ball 54 is disposed in the mounting hole 51; the elastic pressing member 52 is disposed on the first elastic sheet portion 221, and an opening 53 is disposed at a position of the first elastic sheet portion 221 corresponding to the mounting hole 51, where one end of the elastic pressing member 52 passes through the opening 53 and is pressed onto the steel ball 54, so that the steel ball 54 at least partially extends out of the mounting hole 51. A plurality of bar-shaped teeth 55 are uniformly provided on the circumference of the nut surface of the locking bolt 42, and after the locking bolt 42 is coupled between the cross plate portion 212 and the fixed housing 1, the nut of the locking bolt 42 is pressed onto the steel ball 54.

Through the arrangement of the structure, when the locking bolt 42 is rotated to adjust, each bar tooth 55 on the nut of the locking bolt 42 can press the steel ball 54 at intervals, so that the steel ball 54 can be pressed back into the mounting hole 51 by the bar tooth 55, and after the bar tooth 55 is separated from the steel ball 54, the elastic pressing piece 52 can push the steel ball 54 to return to the nut of the locking bolt 42, so that the steel ball 54 can move back and forth in the process of adjusting the locking bolt 42, and a click sound is generated, and a co-worker can make each bar tooth 55 pass through the position of the steel ball 54 to generate a click sound. Thus, when the locking bolt 42 is adjusted by the worker, the rotation amplitude of the locking bolt 42 can be determined according to the generated clicking sound, so that the locking bolt 42 can be adjusted by the worker in a short period. In addition, due to the arrangement of the bar-shaped teeth 55, the steel balls 54 are clamped between the two bar-shaped teeth 55 of the nut of the locking bolt 42, so that the friction force of the steel balls 54 is increased, the locking bolt 42 can be more stably fixed on the transverse plate 212, and the locking force of the locking bolt 42 is improved.

Further, as shown in fig. 3 and 6, a lining 56 is integrally connected to the nut of the locking bolt 42, and each bar-shaped tooth 55 extends to the lining 56.

By providing the lining 56, the nut of the locking bolt 42 can be further ensured to be tightly attached to the transverse plate portion 212, the locking force is increased, and meanwhile, the bar-shaped teeth 55 can be conveniently matched and connected with the steel balls 54.

In a further embodiment, as shown in fig. 4, the elastic pressing member 52 includes a fixed elastic sheet, one end of the fixed elastic sheet is connected to the first elastic sheet 221, and the other end is bent towards the direction of the transverse plate 212 to form a pressing portion 521, and the pressing portion 521 is pressed onto the steel ball 54.

By means of the arrangement of the fixed elastic sheet, the steel balls 54 can be effectively pressed, and meanwhile the structure of the fixed elastic sheet is relatively simple and is convenient to install at the transverse plate 212.

The fixed spring is fixed to the first spring part 221 by a screw.

The fixing elastic sheet is relatively convenient to fix by utilizing the screw, and meanwhile, the fixing elastic sheet is convenient to install and detach subsequently.

It should be noted that, one end of the fixed spring may extend to both sides of the first spring 221 and extend to the edge of the first spring 221, and a hole is formed at a position corresponding to the screw hole of the transverse plate 212, so that when the first spring 221 is fixed to the transverse plate 212 by using a screw, the fixed spring may be fixed to the first spring 221 by using the screw.

Further, the aperture of the mounting hole 51 is gradually reduced along the direction of the fixing socket 1 toward the transverse plate portion 212, and the aperture of the mounting hole 51 located at the side away from the first elastic piece portion 221 is smaller than the diameter of the steel ball 54.

Thus, after the steel ball 54 is arranged in the mounting hole 51, at least part of the steel ball 54 can extend out of the mounting hole 51, and meanwhile, the steel ball 54 cannot fall off from the mounting hole 51, so that the situation that the steel ball 54 is lost is avoided.

In some embodiments, as shown in fig. 7 and 8, the above-mentioned needle probe mounting bracket further includes a screw rod 6 and a gap elimination structure 7, wherein the screw rod 6 is disposed between the fixing bracket portion 21 and the spring bracket portion 22 and is engaged with the screw of the tube portion of the needle probe 9, and the gap elimination structure 7 is connected between the fixing bracket portion 21 and the screw rod 6 to eliminate a gap generated between the spring bracket portion 22 and the fixing bracket portion 21 due to deformation of the spring bracket portion 22 by the gap elimination structure 7 when the spring bracket portion 22 is forced to bend.

With the arrangement of the above structure, when the spring holder portion 22 is forced to bend by finely adjusting the position of the needle detector 9 by controlling the bending of the spring holder portion 22 by the adjustment locking structure 4, the spring holder portion 22 presses the screw rod 6, for example, when the spring holder portion 22 is forced to compress, the second spring piece portion 223 of the spring holder portion 22 is biased in the direction of the riser portion 211, or when the spring holder portion 22 is not forced, the second spring piece portion 223 of the spring holder portion 22 is biased in the direction away from the riser portion 211, the gap eliminating structure 7 automatically adjusts to give the spring holder portion 22 a gap to be biased, thereby avoiding the influence of the screw rod 6 on the bias of the spring holder portion 22.

As shown in fig. 8 and 9, the gap eliminating structure 7 includes a slot 71, a spool, a pin 73 and an elastic body 74, wherein the slot 71 is disposed at one end of the threaded rod, one end of the core 72 is slidably disposed in the slot 71, the other end of the core 72 abuts against the fixed bracket 21, one end of the pin 73 is fixedly connected to the core 72, and the other end of the pin is rotatably disposed on the fixed bracket 21. An elastic body 74 is disposed in the slot 71, and one end of the elastic body 74 is connected to the mandrel 72, and the other end is fixedly connected to the bottom of the slot 71.

By providing such a structure, the mandrel 72 can be relatively expanded and contracted in the slot 71, for example, when the spring holder portion 22 is compressed by force and the second spring piece portion 223 of the spring holder portion 22 is displaced in the direction of the riser portion 211, the mandrel 72 is forced to move toward the slot 71, so that a part of adjustment clearance can be provided without adjusting the fixing holder portion 21 and the spring holder portion 22 in advance, and accordingly, when the spring holder portion 22 is not forced and the second spring piece portion 223 of the spring holder portion 22 is displaced in the direction away from the riser portion 211, the elastic body 74 drives the mandrel 72 to move in the direction of the outside of the slot 71 and the end of the mandrel 72 is always abutted against the riser portion 211, thereby eliminating the clearance between the second spring piece portion 223 and the riser portion 211 in the process. Therefore, when the spring support 22 is stressed to bend, the gap between the spring support 22 and the fixed support 21 can be effectively eliminated, further adjustment by workers is not needed, a large amount of time is saved, and the working efficiency is improved.

The pin 73 may be rotatably disposed on the fixing bracket 21, and may be configured such that a circular hole is provided in the riser 211, so that one end of the pin 73 may just pass through the circular hole, and in addition, the cross-sectional area of the mandrel 72 is larger than that of the pin 73, and then the end face of the mandrel 72 is abutted against the riser 211, and due to the elasticity of the elastic body 74, the mandrel 72 may always be abutted against the riser 211, and the rotation of the pin 73 may not be affected.

The elastic body 74 may be provided as a spring.

The spring has a relatively simple structure, is not easy to damage, and has lower overall manufacturing cost.

Further, the elastic force of the elastic body 74 is greater than the friction force between the mandrel 72 and the slot 71.

By making the elastic force of the elastic body 74 larger than the friction force between the spindle 72 and the slot 71, radial rotation of the spindle 72 can be prevented to some extent.

In some embodiments, as shown in fig. 9, the cross section of the slot 71 is circular, the cross section of the mandrel 72 is also circular, a sliding groove 8 is provided on the inner wall of the slot 71, a sliding block 81 is provided at a position of the mandrel 72 corresponding to the sliding groove 8, and the sliding block 81 is slidably disposed in the sliding groove 8.

Through the setting of spout 8 and slider 81, when guaranteeing that dabber 72 can remove along slotted hole 71, can further avoid making dabber 72 take place to rotate in spout 8, in addition, if dabber 72 rotates wantonly in slotted hole 71, can make the spring rotate along with the rotation of dabber 72 to probably cause the damage of spring, set up this slider 81 and spout 8's structure and prevent dabber 72 rotation simultaneously from effectively improving the life of spring from this.

Further, as shown in fig. 9, two sliding blocks 81 are provided, the two sliding blocks 81 are symmetrically provided with respect to the center of the mandrel 72, two sliding grooves 8 are provided, the two sliding grooves 8 are provided corresponding to the center axis of the slot hole 71, and the two sliding blocks 81 are respectively slidably provided in the two sliding grooves 8.

Thus, the mandrel 72 can slide more stably in the slot 71, and the stability and balance of the movement of the mandrel 71 can be improved.

In other embodiments, the cross-section of the slot 71 is polygonal, and the cross-section of the mandrel 72 is also polygonal, so that the mandrel 72 is coupled into the slot 71.

By the arrangement of the structure, the movement of the mandrel 72 along the slotted hole 71 can be effectively ensured, and the mandrel 72 can be further prevented from rotating in the chute 8.

In some embodiments, as shown in fig. 8 and 9, a connecting post 61 is provided at an end of the threaded rod where the slot 71 is not provided, and the connecting post 61 penetrates the spring bracket 22 and is connected with a manipulation piece 62.

Specifically, a circular hole may be provided on the second elastic piece portion 223, and the cross-sectional area of the connecting post 61 is the same as the area of the circular hole, but smaller than the cross-sectional area of the threaded rod member 6, so that after the connecting post 61 passes through the circular hole, the end of the threaded rod member 6 abuts against the second elastic piece portion 223, thereby ensuring that the threaded rod member 6 can rotate relatively, and meanwhile, cannot fall off from the spring bracket portion 22. The operating member 62 is fixed to an end of the connecting post 61 passing through the second elastic piece 223. In this way, the rotation of the threaded rod 6 can be controlled by the control 62, so that the control is more convenient.

Wherein, the cross-sectional area of the control 62 is larger than the cross-sectional area of the connecting post 61.

In this way, the operating piece 62 is prevented from extending between the fixed bracket portion 21 and the spring bracket portion 22, and the threaded rod 6 is prevented from falling off.
