[0020] Please refer to Figures 1 to 4 , a composite high-strength polymer resin cable tray, including a supporting part 10, a buckling cover part 20, an inserting buckle part 30 and an inserting rod part 40. The inserting buckle part 30 and the inserting rod part 40 are respectively installed at both ends of the bottom of the supporting part 10. When the composite high-strength polymer resin cable trays are combined and connected, adjacent two groups of composite high-strength polymer resin cable trays are inserted and buckled in cooperation with the inserting buckle part 30 and the inserting rod part 40, so that adjacent two groups of composite high-strength polymer resin cable trays are combined and connected along the length direction, so that the supporting part 10 and the buckling cover part 20 are detachably connected together and a cavity for laying cables is formed between the two.

[0021] In this embodiment, a plurality of spaced-apart partition boards 11 are formed on the top of the supporting part 10, and the gaps between adjacent two partition boards 11 or between the partition board 11 and the inner wall of the buckling cover part 20 form a bottom groove 12; a plurality of spaced-apart positioning seats 21 are formed on the top inner wall of the buckling cover part 20, and the positioning seats 21 are clamped in cooperation with the partition boards 11 below them, and the gaps between adjacent two positioning seats 21 or between the positioning seats 21 and the inner wall of the buckling cover part 20 form an upper groove 22. After the buckling cover part 20 is buckled in place with the partition board 11 of the supporting part 10 by using the positioning seats 21, the upper groove 22 and the bottom groove 12 below it can communicate with each other and form a groove body for accommodating cables, so that the cables can be separated during laying, which is convenient for inspection and maintenance. A plurality of fixing holes 23 are formed on the outer wall of the buckling cover part 20, and the plurality of fixing holes 23 are distributed on the side walls at both ends of the buckling cover part 20, so that the whole composite high-strength polymer resin cable tray can be connected and fixed with external supporting components by using the fixing holes 23 and locking parts such as bolts.

[0022] In this embodiment, the buckle part 30 includes a guide seat 31, a double-headed screw 32, two nuts 33 and a hook 34; the rod insertion part 40 includes a fixed seat 41, an extension column 42 and a limit rod 43. The guide seat 31 is installed and fixed at the bottom of the support part 10, and a movable groove 311 is formed in the middle of the guide seat 31. The double-headed screw 32 and the hook 34 are arranged in the movable groove 311, and both ends of the double-headed screw 32 are extended out of the guide seat 31, and both ends of the double-headed screw 32 are sleeved with nuts 33 threadedly connected thereto, so that the double-headed screw 32 can be fixed. The hook 34 is sleeved on the double-headed screw 32 and rotatably connected thereto, so that the hook 34 can deflect and move in the movable groove 311.

In addition, when assembling and connecting adjacent composite high-strength polymer resin cable trays, the hook 34 can be pushed to deflect upward at a certain angle and then released, so that it deflects to abut against the outer edge of the guide seat 31 under the action of gravity. An arc-shaped limiting hook groove 341 is also formed on the hook 34, and the diameter of the limiting rod 43 is matched with the inner diameter of the limiting hook groove 341. After assembling and connecting adjacent composite high-strength polymer resin cable trays, the limiting hook groove 341 can support the limiting rod 43 and prevent it from falling under the action of gravity, so that when the composite high-strength polymer resin cable tray is laid and installed, adjacent composite high-strength polymer resin cable trays can be connected and assembled together to jointly bear the cable gravity, thereby improving the overall load-bearing capacity of the cable tray after laying.
