Description

Technical Field

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for controlling installation, connecting equipment, and transmitting electricity. They are common and indispensable in daily life. Cables often need to be bent during use, so an external mold structure is needed to limit the cable and protect it at the same time, so as to improve the bending performance of the cable.

[0003] As in the prior art, the Chinese patent authorization number is CN213637027U, the application date is: 2020-09-25, and the name is a cable with an anti-bending structure, including a wire body and a central elastic body, the surface of the wire body is sleeved with a spring tube, the surface of the spring tube is fixedly connected with a compression spring, the bottom end of the compression spring is fixedly connected with a pressure plate, the inner side of the spring tube is fixedly connected with a rotating rod, the inner side of the wire body is fixedly connected with a spring rod, the surface of the spring rod is wound with a wire, the inner side of the wire body is provided with a pressure-resistant layer, and the inner side of the pressure-resistant layer is fixedly connected with a central elastic body. The surface of the cable of the utility model is sleeved with a spring tube, which effectively prevents the bending and deformation of the wire inside when the cable is bent, and the spring rod is connected inside the wire winding to facilitate the overall bending between the wires. The surface of the spring tube is wavy, which reduces the connection between its surface and the ground, thereby reducing the dust adhering to the surface, and the cable has a certain pressure resistance.

[0004] However, the above patent still has the disadvantage that due to the wide variety of cables with different sizes, it is easy to be unable to install the cables due to the different thicknesses of the cables when clamping and limiting the cable surface, further reducing the applicability of the outer mold structure.

[0005] Therefore, in order to solve this problem, the utility model provides a cable assembly outer mold structure which can improve the bending performance. Utility Model Content

[0009] Preferably, a clamping sleeve is fixedly connected to one side of the upper clamping hoop, a clamping block is fixedly connected to one side of the lower clamping hoop, and the clamping sleeve is clamped on the surface of the clamping block.

[0010] Preferably, an open groove is provided on one side of the corrugated tube, and the open groove is located in the same direction of the clamping sleeve and the clamping block.

[0014] Preferably, the ends of the upper clamp and the lower clamp are rotatably connected to a connecting block via a rotating shaft.

[0015] Compared with the prior art, the utility model provides a cable assembly outer mold structure that can improve bending performance, and has the following beneficial effects:

[0016] The outer mold structure of the cable assembly that can improve the bending performance can extrude and fix the surface of the cable through the cooperation between the guide rail, the sliding block, the support rod and the extrusion plate. Through this arrangement, it is possible to clamp and fix cables of different sizes, preventing the problem of installation failure due to size differences, and further improving the applicability of the outer mold structure.

[0025] In the utility model, when in use, the upper clamp 1 and the lower clamp 2 are first stretched open, so that the corrugated tube 3 is stretched open at the same time, so that it can be covered on the surface of the cable, and then the upper clamp 1 and the lower clamp 2 are merged, and the surface of the cable is clamped by the extrusion plate 7. At the same time, the extrusion plate 7 will push the support rod 6 to push the sliding block 5 to slide on the guide rail 4, so as to clamp and fix the cables according to the sizes of different cables, so as to protect and limit the cables during bending, and further improve the bending performance.

[0026] Reference Figure 3 A clamping sleeve 8 is fixedly connected to one side of the upper clamp 1 , a clamping block 9 is fixedly connected to one side of the lower clamp 2 , and the clamping sleeve 8 is clamped on the surface of the clamping block 9 .

[0027] In the utility model, by setting the clamping sleeve 8, when the upper clamp 1 and the lower clamp 2 are directly merged, the clamping sleeve 8 can be clamped on the surface of the clamping block 9, so that the upper clamp 1 and the lower clamp 2 can be directly and quickly fixed. At the same time, when disassembling at a later time, it is only necessary to increase the bottom angle of the clamping sleeve 8 to separate the clamping sleeve 8 and the clamping block 9, so that the upper clamp 1 and the lower clamp 2 can be directly disassembled quickly.

[0028] Reference Figure 2 An open groove 31 is provided on one side of the bellows 3 , and the open groove 31 is located in the same direction of the clamping sleeve 8 and the clamping block 9 .

[0029] In the utility model, the opening groove 31 is opened so that the corrugated tube 3 can be divided into two parts, and the other sides of the two parts are fixed to each other, so that when the upper clamp 1 and the lower clamp 2 are turned over, the two parts of the opening groove 31 can be simultaneously opened, so that the cable can be directly wrapped into the interior of the corrugated tube 3, thereby playing a protective role.

[0032] Reference Figure 4 A support spring 10 is sleeved on the surface of the guide rail 4 , and the end of the support spring 10 is fixedly connected to the sliding block 5 .
