Description

Technical Field

[0001] The invention relates to the technical field of cable laying brackets, in particular to a cable laying bracket. Background Art

[0002] The cable laying bracket is a device used to support and fix cables. It can keep the cables neat and orderly during the laying process to avoid crossing and squeezing each other. At the same time, it can also separate the cables from the ground and walls to prevent the cables from mechanical damage, chemical corrosion and moisture. For example, in the cable trench, the laying bracket will lift the cables off the bottom of the trench to prevent the cables from being soaked by accumulated water. In the shaft of a building, the bracket can fix the cables to prevent the cables from sagging due to their own weight, thereby ensuring the safe operation of the cables.

[0003] The cable laying bracket will be installed in the cable trench. When the cable laying bracket has problems and needs to be repaired or replaced, many difficulties may be encountered. When removing the damaged bracket, the cable needs to be moved away first, resulting in the removal and replacement of the bracket parts may interfere with the normal operation of the cable, making it inconvenient to replace and maintain the cable laying bracket.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing cable laying brackets on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which cannot achieve the desired effect.
