[0002] When installing communication cables, cable ducts are usually used to ensure the safe, orderly and efficient laying of cables.

[0003] A Chinese patent with application publication number CN2646917Y discloses a latch-type metal wire duct. In the patent, at least two latches are fixed on the bottom surface of the cover plate, and a clamping device for clamping the latches is provided at the corresponding position of the duct body. When the cover plate is covered on the duct plate, the latches are inserted and clamped by the clamping device, thereby fixing the cover plate on the duct body. The latches are on the bottom surface of the cover plate, and the clamping device is inside the duct body.

[0004] When using the above patent, we found that the device does not have the ability to fix the cable. When the cable is placed in the cable duct, it is easy for the cable to move and become entangled, which makes it inconvenient for workers to inspect and repair. Therefore, we proposed a cable duct for communication cables. Summary of the invention
