[0021] The adjusting positioning assembly 7 includes a support frame 8, which is fixedly installed in the middle of the bottom of the cable tray body 1. A strip-shaped housing 9 is fixedly installed on the top of the support frame 8. A drive shaft 10 is rotatably installed inside the strip-shaped housing 9, and both ends of the drive shaft 10 extend to the outside of the strip-shaped housing 9. An adjusting block 11 is fixedly installed on one end of the drive shaft 10. An adjusting thread 23 is provided on the outer side of the end of the drive shaft 10 away from the adjusting block 11. A locking nut 24 is installed on the outer thread of the adjusting thread 23, and one side of the locking nut 24 contacts the outer side of the strip-shaped housing 9. Two drive gears 12 are fixedly installed inside the strip-shaped housing 9 and on the outer side of the drive shaft 10. A transmission gear 13 is meshed with the outer side of the drive gear 12. An adjusting screw 14 is fixedly installed at the bottom of the transmission gear 13, and the bottom end of the adjusting screw 14 moves through and extends into the interior of the support frame 8. A positioning bearing 15 is rotatably installed at the bottom of the adjusting screw 14. The positioning bearing 15 is fixedly installed at the bottom of the inner side of the cable tray body 1. A threaded movable sleeve 16 is threadedly installed inside the support frame 8 and outside the adjusting screw 14. A first connecting shaft 17 is symmetrically fixedly installed on the outer side of the threaded movable sleeve 16. A connecting bar 18 is rotatably installed on the first connecting shaft 17. A second connecting shaft 19 is rotatably installed on the end of the connecting bar 18 away from the first connecting shaft 17. A movable plate 20 is fixedly installed on the side of the second connecting shaft 19 away from the connecting bar 18. Three movable bars 21 are evenly fixedly installed on the side of the movable plate 20 away from the second connecting shaft 19. Three second arc-shaped grooves 22 are evenly opened on the side of the movable bar 21 away from the movable plate 20. The second arc-shaped grooves 22 are horizontally aligned with the first arc-shaped grooves 6. A positioning sliding hole 25 is opened through the top and bottom of one end of the movable plate 20. A positioning sliding rod 26 is slidably installed inside the positioning sliding hole 25. Both ends of the positioning sliding rod 26 are fixedly connected to the inner wall of the cable tray body 1.

[0022] In use, the interaction of the cable tray body 1, positioning strip 5, first arc groove 6 and adjusting positioning component 7 makes it easy to separate and position cables during the use of high-strength cable tray, improving the stability and regularity of cable laying, thus achieving better practicality. Furthermore, the interaction of the positioning sliding hole 25 and positioning sliding rod 26 makes it easier for the movable plate 20 to achieve better stability when moving, thus ensuring that the adjusting positioning component 7 can work stably.

[0023] Working principle: During operation, firstly, place the cables to be installed into the first arc-shaped groove 6 outside the positioning strip 5 inside the cable tray body 1. Then, hold the adjusting block 11 to keep the drive shaft 10 stationary. Then, loosen the locking nut 24 to release the positioning of the drive shaft 10. Then, rotate the adjusting block 11 to drive the drive shaft 10 to rotate. The drive shaft 10 drives the drive gear 12 to rotate, the drive gear 12 drives the transmission gear 13 to rotate, and the transmission gear 13 drives the adjusting screw 14 to rotate. The adjusting screw 14 drives the threaded movable sleeve 16 to move downward. The threaded movable sleeve 16 drives the first connecting shaft 17 to move downward. The first connecting shaft 17 drives the connecting strip 18 to move. The connecting strip 18 pushes the movable plate 20 to move through the second connecting shaft 19. The movable plate 20 moves in the positioning sliding hole 25. The movable plate 20 is slidable on the outside of the positioning slide bar 26 to ensure better stability during movement. At the same time, the movable plate 20 drives the movable bar 21 to move, and the movable bar 21 drives the second arc groove 22 to contact the outside of the cable. As the movable bar 21 moves, the cable is separated and positioned between the first arc groove 6 and the second arc groove 22. Then, the rotation of the adjusting block 11 is stopped, and the adjusting block 11 is held to keep the drive shaft 10 stationary. Then, the locking nut 24 is tightened to reposition the drive shaft 10. Then, the adjusting block 11 is released to complete the separation and positioning operation of the cable inside the cable tray body 1. This makes it easier to separate and position the cable during the use of the high-strength cable tray, improves the stability and regularity of the cable laying, and thus facilitates better practicality.
