Description

Cable type is adjustable horizontal bar

Technical field

The invention belongs to sports apparatus field, specifically refer to the adjustable horizontal bar of a kind of cable type.

Background technology

Horizontal bar is a kind of important physical training utensil, extensively arrange in the large primary school that teenager concentrates, in addition along with people are to the attention gradually of body building, the also common distribution in places such as residential blocks, it is generally made up of two poles cross bar, what extensively see is all that height can not regulate, and the height two groups that is set to had connects all-in-one-piece mutually, though this facilitates much will take larger space, place; In actual life, people need a kind of horizontal bar that can just regulate to use to facilitate people's body-building of differing heights.

Summary of the invention

Object of the present invention is the new adjustable horizontal bar of technical scheme cable type providing a kind of horizontal bar, and it can eliminate the deficiency of said apparatus.

Technical scheme of the present invention realizes like this, it comprises the cross bar of circular tube shaped, upper rack posts, lower fulcrum bar and clamping screw, one section of inner tubal wall of described two upper rack posts lower end is processed with the contrary internal thread of rotation direction, shaft-like bolt and adjusting bolt is had to screw in respectively wherein, on the lower fulcrum bar inner tubal wall of adjusting bolt lower end, all affixed one containing the baffle plate of centre bore, between adjusting bolt and baffle plate, all device has a pressure bearing, and the lower end of adjusting bolt slightly attenuates and stretches into all downwards in the centre bore of baffle plate; The lower end of adjusting bolt is on the right connected with conical gear, and one is attached thereto by the tube wall of a rocking arm through lower fulcrum bar with its mutually meshing lower conical gear; Two pole level connection joints get up and gang up at the lower end part of two lower fulcrum bars by one tubular rod and connecting rod, and a flexible axle passes connecting rod and two ends is connected to the center, adjusting bolt lower surface on upper conical gear and the left side.

The invention has the beneficial effects as follows and horizontal bar height can be allowed adjustable, use with the people's body-building adapting to differing heights.

accompanying drawing illustrates:

Fig. 1 is that the design illustrates the front view (higher state, conical gear up and down and the zoomed-in view of parts that is connected containing device in the lower fulcrum bar of the right) of horizontal bar.

Fig. 2 is the front view of the horizontal bar being in the state of turning down.

In each figure, 1 is cross bar, and 2 is upper rack posts, and 3 is lower fulcrum bar, and 4 is clamping screw, and 5 is adjusting bolt, and 6 is pressure bearing, and 7 is rocking arm, and 8 is upper conical gear, and 9 is lower conical gear, and 10 is flexible axle, and 11 is baffle plate, and 12 is connecting rod.

detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the design comprises cross bar 1 and coupled left and right upper rack posts 2, left and right lower fulcrum bar 3, the clamping screw 4 on top, it is one thin one thick that upper and lower pole is all that circular tube shaped distributes up and down, one section, the upper end of lower fulcrum bar is inserted in the lower end of upper rack posts, on tube wall near the upper end that clamping screw is fixed on lower fulcrum bar, highly regulate put in place after upper lower fulcrum bar can be connected and fixed locking by it, play the safety effect that assistant reinforcement is firm, one section of inner tubal wall of left and right two upper rack posts 2 lower end is processed with the contrary internal thread of rotation direction respectively, the two shaft-like bolts matched with it and adjusting bolt 5 screw in wherein respectively, on the inner tubal wall of the lower fulcrum bar 3 of adjusting bolt lower end, horizontal affixed one containing the baffle plate 11 of centre bore, all pressure bearing 6 on device between adjusting bolt 5 and baffle plate 11, it can keep the rotation of adjusting bolt to regulate smooth and easy flexibility when bearing pressure, the lower end of adjusting bolt 5 all slightly work attenuates and stretches into downwards in the centre bore of baffle plate 11 to limit the position of adjusting bolt and upper rack posts, aforesaid upper lower fulcrum bar, clamping screw, adjusting bolt, pressure bearing, baffle plate is all each symmetrical mounting around, the lower end being in the adjusting bolt under the baffle plate of the right is connected with conical gear 8, its flank of tooth is downward, one is attached thereto by the outside tube wall of a rocking arm 7 through lower fulcrum bar 3 with its mutually meshing lower conical gear 9, under the drive that mat rocking arm rotates, conical gear can conical gear rotation in meshing drive, thus adjusting bolt is rotated in upper rack posts regulate the height of upper rack posts, connecting rod 12 is a tubular rod, two pole level connection joints get up and gang up at the lower end position of two lower fulcrum bars 3 by it, one can transmit the flexible axle 10 of torsion through connecting rod 12, the center of the upper conical gear 8 in the right-hand member of flexible axle 10 lower fulcrum bar is on the right affixed, and the center, adjusting bolt lower surface in the lower fulcrum bar of the left end on the left side of flexible axle 10 is affixed.Like this, the adjustable horizontal bar of cable type of the design is just described, during concrete operations use when needs are adjusted to lower state (shown in Fig. 2) by higher state (shown in Fig. 1), can first unscrew clamping screw 4, shake rocking arm 7 again, the meshing of conical gear up and down in the lower fulcrum bar of the right can drive the adjusting bolt 5 on the right to rotate in upper rack posts and carry out height adjustment up and down to it, owing to there being the connection restraining function of cross bar 1, in this adjustment process, upper rack posts can not rotation on occurred level direction thus this adjustment can be carried out smoothly, height regulates synchronous is therewith that this rotary torsion also can pass in the adjusting bolt on the left side by flexible axle 10 by upper conical gear 8, carry out same synchronous interaction to the upper rack posts on the left side to regulate, because two ends the turning in same level of a flexible axle is objectively contrary, for the adjustment screw thread process in the upper rack posts of left and right must be become different rotation direction by synchronous the adjustment in the same way of reaching left and right upper rack posts, an i.e. left-handed dextrorotation, the screw thread of the adjusting bolt in like manner matched with it also does same processing, this ensures that there synchronous adjustment in the same way, meet the requirement of the design, namely horizontal bar locks by the upper lower fulcrum bar of clamping screw by both sides after putting in place to low adjustment, ensure that it relative movement can not occur in the horizontal direction, and the supporting role of baffle plate also fully can ensure lower fulcrum bar relative stability in the vertical direction, the acting in conjunction of both can ensure the security and stability of the design's horizontal bar entirety, otherwise contrary operation just can complete and heighten adjustment, should be noted in addition and whole for connecting rod position should be embedded in underground when device horizontal bar.The horizontal bar one people side of the design can complete height and regulate, simple and convenient, can meet the body-building needs of people in the use of reality greatly.
