In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Example 1:

referring to fig. 1 and 2, the present embodiment provides a disc, which is suitable for being used in a wire coil, including: the locking device comprises a circular disc body 1 and a plurality of locking units which are distributed on the circular disc body 1 in an array manner around the circumference of the axis of the circular disc body; the inner diameter of each specific multi-channel locking unit is sequentially increased outwards from the axis of the circular disc body 1, so that the multi-channel locking units can be matched with the cylinders 7 with different outer diameters to form a wire coil suitable for different winding requirements.

In an optional case, each locking unit comprises a plurality of locking holes 2 distributed at intervals and surrounding into a ring shape along the circumferential direction of the axis of the circular disc body 1. The locking hole 2 can be matched with a screw to realize locking matching with the cylinder 7, and under the structure, the disc body of the embodiment is detachably connected with the corresponding cylinder 7, so that the disc body is convenient to use and can be replaced and assembled for recycling.

Because the locking hole 2 needs to be arranged on the disk, and the locking hole 2 forms a tight fit with the cylinder 7, in such a structure, if the thickness of the whole disk is designed to be thicker, on one hand, the raw material cost is increased, and on the other hand, the weight of the whole disk is increased, so that the inconvenience in use is caused. In consideration of this problem, the disk designed in this embodiment does not increase the thickness of the entire disk body, but has the following structure to achieve both the cost and strength.

Specifically, a plurality of radial reinforcing ribs 3 are uniformly arranged on the surface of one side of the circular tray body 1 at intervals. On the basis, a plurality of circumferential reinforcing ribs 4 can be arranged on the surface of one side of the circular tray body 1 at intervals and uniformly in the circumferential direction around the axis of the circular tray body 1; and each radial stiffener 3 forms a cross fit with each circumferential stiffener 4. That is, the effect of improving the strength of the whole disk without increasing the thickness of the whole disk is realized by the radial reinforcing ribs 3 and the circumferential reinforcing ribs 4 which are arranged in a criss-cross manner.

On the basis of the above structure, each locking hole 2 may be alternatively disposed to penetrate the radial rib 3, so that the radial rib 3 may be used to reinforce the connection strength between the disk and the cylinder 7.

Example 2:

referring to fig. 1 and 7, in addition to the disc of embodiment 1, the present embodiment provides a disc including an extended disc body 5 having an annular structure and adapted to be fitted around a circumferential side wall of a circular disc body 1.

Specifically, the disk in embodiment 1 can be assembled to form coils with different structures by matching with the cylinders 7 with different outer diameters as required, in this case, when the cylinder 7 is matched with the locking unit located at the outermost ring on the disk, in order to make the radial dimension formed between the circumferential outer side wall of the disk and the circumferential outer side wall of the cylinder 7 sufficient for winding the cable, the extension disk 5 is designed in this embodiment.

On the basis of the above structure, in order to facilitate the assembly and the matching between the circular tray body 1 and the extension tray body 5, the circular tray body 1 and the extension tray body 5 in the embodiment are both formed by injection molding of thermoplastic plastics. The thermoplastic material is at least one of polypropylene, polystyrene, acrylonitrile-butadiene-styrene terpolymer, continuous fiber reinforced polypropylene engineering plastic or nylon reinforced material. On the basis of the structure, the extension disc body 5 is suitable for forming interference fit with the circular disc body 1, and the structure of the interference fit can effectively guarantee the stability of the overall structure formed after assembly.

On the basis of the above structure, in view of further improving the structural stability of the whole structure during repeated use, in an optional case, the inner hole edge of the extension disc body 5 is further provided with a baffle 51 adapted to be tightly fitted with one of the axial side end faces of the circular disc body 1. The baffle 51 may be coupled to a side end surface of the tray body connected to the cylindrical body 7, or may be coupled to a side end surface of the tray body away from the cylindrical body 7, which is not limited in this embodiment. It should be noted that, here, a threaded mating hole for locking and matching with the circular tray body 1 can be prefabricated on the baffle plate 51, so that the locking and matching between the baffle plate 51 and the circular tray body 1 can be realized by fastening screws.

The extension tray body 5 of the present embodiment may be further modified in the following structure: namely, the extension disc body 5 is formed by combining two semicircular annular bodies 6; and a containing groove suitable for being embedded into the part of the circular disc body 1 is arranged in any one of the semicircular annular bodies 6. Under this kind of structure, all begin to have the perforation 61 that is suitable for fastening screw to pass on two semi-circular ring bodies 6, and prefabricated the mounting hole with above-mentioned perforation 61 adaptation on circular disk body 1, like this, after pegging graft circular disk body 1 and two semi-circular ring bodies 6 and target in place, can realize the fastening connection between circular disk body 1 and the semi-circular ring body 6 through fastening screw.

Example 3:

referring to fig. 8 and 9, on the basis of the disc of embodiment 1 or embodiment 2, the present embodiment provides a volume-variable plastic wire coil, including: the disc of embodiment 1 or embodiment 2, and a cylinder 7 adapted to be tightly fitted with the locking hole 2 of the disc by a screw.

For the disk of this embodiment, in view of further improving the firmness of the coupling between the cylinder 7 and the disk and the stability during use, the following design is made in this embodiment:

in combination with the hollow cylindrical body 7 capable of saving material cost, a reinforcing unit which is suitable for being inserted into the cylindrical body 7 and is suitable for being in contact fit with the inner wall of the cylindrical body 7 is further arranged on the side end face, facing the cylindrical body 7, of the disk, wherein the reinforcing unit is matched with the plurality of locking units on the disk one by one.

For example, in an alternative case, each reinforcing unit includes a plurality of reinforcing columns 71 distributed at intervals and surrounding into a ring shape along the circumferential direction of the axis of the circular disc body 1; the reinforcing post 71 is preferably a cylindrical structure of the reinforcing post 71, so that the reinforcing post 71 can be inserted into the interior of the cylinder 7 to be in contact fit with the inner wall of the cylinder 7. As another alternative, each reinforcing unit includes a reinforcing ring that surrounds the axis of the circular disk 1 in the circumferential direction to form a ring shape. Both of these two situations satisfy the use requirements of the present embodiment, which is not absolutely limited. It should be noted that the radial gap formed between each two adjacent reinforcing units satisfies the wall thickness requirement of the cylinder 7, that is, when the cylinders 7 with different sizes are assembled with the circular plate 1, the reinforcing units do not form an obstacle to the above-mentioned assembly.

In conclusion, when the cylinder 7 of the embodiment needs to be assembled with the circular disc 1 for use, the corresponding locking unit is selected on the disc according to the outer diameter of the cylinder 7, then the reinforcing unit is inserted into the cylinder 7, and the locking hole 2 and the screw hole prefabricated at the axial end of the cylinder 7 are screwed by the screw to realize the fastening fit between the disc and the cylinder 7.
