Detailed Description

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 to 4, the present embodiment provides a tray body for preventing a wire from being bent, including: both axial end faces are a substrate 1 which is concave-convex continuously distributed and encloses to form a circular structure and a circular enclosing baffle 2 connected with the circumferential outer side wall of the substrate 1. The two parts can be directly and integrally molded by injection to simplify the processing procedure, and simultaneously, the molding strength of the two parts can be increased, so that the problem that the strength of the connecting part formed after split processing does not reach the standard is avoided. For making whole disk body reach the light-weighted purpose, the disk body adopts injection moulding's mode to form the plastic drum, compares pure metal drum that holistic weight is lighter, and the cost is synchronous lower.

The following embodiments are described in conjunction with the drawings:

firstly, the base body 1 is a circular structure in combination with the shape of the disc body of a general wire coil, so that the base body 1 itself is also a circular structure, and on the other hand, both end faces in the axial direction of the base body 1 are both in a structure in which the projections and the depressions are continuously distributed. In detail, each axial end surface of the base body 1 comprises a concave surface 11 and a convex surface 12 which are continuously distributed, and the concave surface 11 and the convex surface 12 of the two axial ends have the following relationship: namely, the concave surface 11 at one axial end of the base body 1 is opposite to the convex surface 12 at the other axial end of the base body 1, so that the cross section of the whole base body 11 is in an L shape and an inverted L shape which are distributed continuously and are connected end to end.

In addition to the above structure, it should be noted that the shapes of the concave surface 11 and the convex surface 12 may be both regular shapes or irregular shapes, and this embodiment is not limited in any way. The drawings only exemplify a case where the base 1 is formed with a fan-shaped structure and a rectangular structure in a continuous concavo-convex manner. And for the concave-convex continuity formed by the fan-shaped structure and the rectangular structure, the surface area of the fan-shaped structure is larger than that of the rectangular structure. It should also be noted that here the large arc end face of the sector structure is connected to the circular surround 2.

In addition to the above structure, it is further explained that at least one wire groove 3 penetrating through the concave surface 11 and the convex surface 12 at both ends of the base body 1 in the axial direction is formed on the base body 1; the conductor track 3 extends through at least two concave surfaces 11 and two convex surfaces 12 which are continuously distributed.

In connection with the natural curve of the detection section of a typical wire, an alternative is for example the case where the conductor groove 3 extends along an S-shape, which is intended to adapt to the natural curve of the wire, although the curvature of each arc turn in the S-shape here may be large or small, designed in particular in connection with the natural curve of a typical breakable type of core wire. Under the structure, the wire groove 3 can simultaneously penetrate through the concave surface 11 and the convex surface 12 at the two axial ends of the base body 1 without bending, namely, the cable can enter into the other shaft end from one shaft end of the base body 1 along the extending state of the natural curve of the cable, and the problem of damage or even breakage of the core wire in the cable caused by bending can be directly avoided for the extending state of the natural curve of the cable.

Example 2:

on the basis of the disc body for preventing the wire from being bent in the embodiment 1, two connected wire grooves 3 extending in opposite directions are formed on the base body 1 of the disc body for preventing the wire from being bent in the embodiment. The two wire grooves 3 are symmetrically distributed.

This embodiment makes this drum can realize two-way line taking-up, line entering and line storage operation through a pair of metallic channel 3 of design in the use, and the extending direction that no longer receives single metallic channel 3 existence on the drum fixes the problem that can only single direction line taking-up, line entering and line storage operation, has also improved the flexibility in the whole drum use promptly.

Example 3:

referring to fig. 1, on the basis of the wire bending prevention tray body in embodiment 1 or embodiment 2, a pair of pin pulling holes 4 is further formed in the base 1 of the wire bending prevention tray body provided in this embodiment; and the hole wall of the poking pin hole 4 is formed with a metal insert through insert injection molding.

Through the design of the metal insert, the structural strength of the poking pin hole 4 can be directly and effectively improved, so that the structural strength of the poking pin hole 4 can not be influenced on the basis that the disk body is light in weight, and the normal use requirement of the wire coil can be met by matching with external equipment.

Example 4:

referring to fig. 5, on the basis of the wire bending prevention disc body in embodiment 1 or embodiment 2 or embodiment 3, a diameter-adjusting connecting piece 5 is further embedded in the wire groove 3 of the wire bending prevention disc body provided in this embodiment.

More specifically, the diameter-adjusting joint 5 is formed to extend along the wire guide groove 3, and the cross section of the diameter-adjusting joint 5 is arc-shaped.

It should be noted that, the diameter-adjusting joint 5 in this embodiment may be made of an elastic material, such as rubber, so that the diameter-adjusting joint 5 may be directly clamped in the wire guide groove 3 by the elasticity of the diameter-adjusting joint, or may be directly pulled out of the wire guide groove 3 when it needs to be detached.

The purpose of the diameter-adjusting connecting piece 5 designed in this embodiment is to adjust the use requirements of cables with different outer diameters, that is, when the outer diameter of the cable is small, the diameter-adjusting connecting piece 5 can be embedded into the wire guide groove 3, and then the cable is clamped into the diameter-adjusting connecting piece 5; when the outer diameter of the cable is large, the cable can be directly snapped into the conductor groove 3. It should be noted that, in the case of different cable sizes, it is not necessary to arrange many specifications of the diameter-adjusting connectors 5, but the cable sizes are divided into a large size and a small size according to the outer diameter of the cable, where the large size is directly used with the wire guide groove 3, and the small size is used with the diameter-adjusting connectors 5. Therefore, the cable is only required to be roughly divided into two cases of a large size and a small size, and mainly, the wire guide groove 3 itself in the embodiment penetrates through the concave surface 11 and the convex surface 12 at the same time, so that the extending process of the wire guide groove 3 is also in a concave-convex continuous structure, and even if the outer diameter of the cable is smaller than the inner diameter of the wire guide groove 3, the cable cannot be directly separated from the wire guide groove 3 due to the concave-convex matching of the wire guide groove 3. The present embodiment is only intended to optimize the use of cables with a relatively small inner diameter by means of the reducing joints 5.

Example 5:

on the basis of the wire bending prevention disc body of embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4, the present embodiment provides a wire coil, including: the wire-bending-prevention tray of embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4.
