[0002] Cable tray is a device used to support cables. It is usually installed on the ceiling inside or outside a building. It can support and fix cables, keep them neatly laid out, and play a protective role. Cable tray can effectively manage cables, avoid cable crossing and entanglement, facilitate maintenance and replacement, and is also beneficial to fire prevention and safety. In traditional cable trays, the two C-shaped steels used to carry cables are connected and fixed by a plate and several screws. In order to facilitate the installation of cable trays, people have improved the installation method.

[0003] After searching, the authorization announcement number CN213937301U and the authorization announcement date 2021.08.10 disclose a steel beam cable tray for electric power engineering, which involves the field of cable trays, including a first bridge and a second bridge, both of which include a bottom plate and two side plates fixed on both sides of the bottom plate, and both of which are "U"-shaped groove structures, and a clamp is respectively provided on the outer surface of the two side plates at one end of the first bridge, and a clamp for clamping the clamp is respectively provided on the outer surface of the two side plates at one end of the second bridge.

When the above-mentioned steel beam cable bridge of the electric power engineering is in use, dust is easily trapped in it due to its open top, and its protection capability is insufficient. In addition, since the partition plate is fixed on the bottom plate, the spacing space cannot be independently allocated according to the diameter of the cable, which is inconvenient to use.
