The connecting block 14 is fixedly installed on the outside of the cover plate 4.

[0022] The adjustment assembly 8 includes a frame 15, which is U-shaped. The frame 15 is fixedly installed at the middle of the bottom outer side of the cable tray body 1. An adjustment shaft 16 is rotatably installed at the bottom inner side of the frame 15, and one end of the adjustment shaft 16 extends to the outside of the frame 15. An adjustment block 17 is fixedly installed at the end of the adjustment shaft 16 located outside the frame 15. Two adjustment gears 18 are fixedly installed inside the frame 15 and outside the adjustment shaft 16. The tops of the two adjustment gears 18 are meshed with rotating gear discs 19. A positioning shaft 20 is rotatably installed in the middle of the rotating gear discs 19, and the positioning shaft 20 is fixedly installed on the cable tray body 1. On the outer side of the main body 1, an arc-shaped limiting groove 24 is provided through the top of the rotating gear disk 19, and the arc of the arc-shaped limiting groove 24 is 180 degrees.

A movable seat 23 is fixedly installed on the top of the movable shaft 22, and two movable seats 23 are symmetrically fixedly installed on the outer side of the cover plate 4.

[0023] During use, the interaction of the cable tray body 1, support bar 2, arc-shaped support seat 3, arc-shaped positioning seat 6, connecting bar 5, cover plate 4, elastic positioning component 7, and adjusting component 8 enables the resin-based composite lightweight high-strength cable tray to separate and position cables, improving the regularity and stability of cable laying and thus achieving better practicality. Furthermore, the interaction of the arc-shaped limiting groove 24 and the limiting slider 25 limits the rotation range of the rotating toothed disc 19 during use, thereby ensuring that the adjusting component 8 can work stably.

[0024] Working principle: During operation, firstly, rotating the adjusting block 17 drives the adjusting shaft 16 to rotate. The adjusting shaft 16 drives the two adjusting gears 18 to rotate simultaneously. The adjusting gears 18 drive the rotating gear disk 19 to rotate. Under the action of the arc-shaped limiting slide groove 24, the rotating gear disk 19 moves outside the limiting slider 25. At the same time, rotating the gear disk 19 drives the connecting shaft 21 to move upward in an arc. The connecting shaft 21 drives the movable bar 26 to move. The movable bar 26 pushes the movable seat 23 upward through the movable shaft 22. The movable seat 23 drives the cover plate 4 upward. The cover plate 4 drives the four support rods 12 to slide upward inside the four sleeves 10 through the four connecting blocks 14. The support rods 12 drive the movable block 11 to move upward. The upward movement of the movable block 11 compresses the positioning spring 13, causing the positioning spring 13 to undergo elastic deformation. At the same time, the cover plate 4 drives the connecting bar... 5. Move upwards, and the connecting strip 5 drives the arc-shaped positioning seat 6 to move upwards. After the arc-shaped positioning seat 6 moves to a suitable height, stop rotating the adjusting block 17. Then, lay the cables inside the five arc-shaped support seats 3 respectively. Then release the adjusting block 17. At this time, under the dual action of gravity and the rebound force of the positioning spring 13, the movable block 11 is pushed downwards. The movable block 11 drives the support rod 12 to move downwards. The support rod 12 drives the cover plate 4 to move downwards through the connecting block 14. The cover plate 4 drives the arc-shaped positioning seat 6 to move downwards through the connecting strip 5. The arc-shaped positioning seat 6 moves downwards and positions the cables inside the arc-shaped support seat 3, completing the separation and positioning operation of the cables inside the cable tray body 1. In this way, the resin-based composite lightweight high-strength cable tray can separate and position the cables during use, improving the regularity and stability of cable laying, thus facilitating better practicality.
