Technical Field

[0001] This utility model relates to the field of protection devices, and in particular to a cable bending tension limit protection device. Background Technology

[0002] A cable is a conductor made of one or more mutually insulated conductors and an outer insulating protective layer. It is used to transmit electricity or information from one place to another. During the bending process of a cable, protective devices are needed to limit the degree of bending and tension of the cable to prevent the cable from being damaged due to excessive bending or excessive tension. These devices usually include components such as limiters and fasteners to ensure that the cable maintains appropriate tension and shape when bending.

[0003] Most existing protection devices are unidirectional and may only be applicable to specific cables. When other types or specifications of cables need to be protected, new protection devices may need to be redesigned and manufactured. This not only greatly limits the scope of application, but may also delay the progress of the project. At the same time, it may cause the cable to be damaged during bending, affecting the performance and service life of the cable.

[0004] Therefore, since most of the existing protection devices are unidirectional and fixed, their applicability may be greatly limited when other types or specifications of cables need to be protected. This may also delay the progress of the project and even affect the performance and service life of the cable. A cable bending tension limit protection device can be designed with an adjustable limit structure to improve the applicability of the device. Utility Model Content

When the second bending track 102 is picked up, the arc-shaped locking strips 103 drive the second bending track 102 to fit and connect with the inner wall of the first bending track 1.

[0025] Please see Figures 3-4 In this embodiment, the rectangular telescopic sleeve 201 is fixedly connected to the second bending track 102. The fixing pin 203 passes through the rectangular telescopic sleeve 201 and is positioned and connected to the rectangular telescopic plate 202 through the fixing hole 204.

The circular telescopic sleeve 302 is fixedly connected to the second bending track 102 through the connecting hole 104.

Then, the second bending track 102 is picked up, and the arc-shaped clamping strip 103 drives the second bending track 102 to connect with the inner wall of the first bending track 1. Then, depending on the cable thickness, the L-shaped telescopic rod 207 is adjusted laterally and vertically along the first square telescopic sleeve 205 and the second square telescopic sleeve 206 by adjusting the positioning pin 208. After reaching the appropriate length and width, the positioning pin 208 is picked up and passed through the first square telescopic sleeve 205 and the second square telescopic sleeve 206. 6.

This solves the problem that most existing protection devices are unidirectional fixation, and when other types or specifications of cables need to be protected, the scope of application may be greatly limited, and the project progress may be delayed, or even the performance and service life of the cables may be affected.
