[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1 to 5 This utility model provides an expandable cable tray structure, comprising a cable tray body 1 and two slides 2. The two slides 2 are respectively disposed on the inner walls of both sides of the cable tray body 1. Connecting rods 3 are fixedly connected to both ends of the inner walls of the two slides 2. A cover 4 is fitted on the upper surface of the two slides 2. Connecting blocks 5 are fixedly installed on the inner walls of both ends of the cover 4. The connecting blocks 5 are T-shaped. Connecting grooves that are adapted to the connecting blocks 5 are opened on the upper surfaces of both ends of the two slides 2. Mounting brackets 6 are fixedly installed on both ends of the upper surface of the cover 4. Locking blocks 7 are fixedly installed on the outer surfaces of the two slides 2. Locking slots 8 are opened on both sides of the inner walls of the cable tray body 1. The locking blocks 7 and the locking slots 8 are both T-shaped and are fixedly connected to the inner walls of the locking blocks 7 and the locking slots 8.
[0024] To facilitate the expansion of the cable tray, a mounting frame 9 is fixedly installed on the front wall of the cable tray body 1. A threaded rod 10 is rotatably connected to the inner wall of the mounting frame 9. The threaded rod 10 passes through the inner wall of the mounting frame 9 and extends to the lower surface of the mounting frame 9. A turntable 11 is fixedly installed at the bottom end of the threaded rod 10. A driving block 12 is fixedly installed on the outer wall of a slide 2. The driving block 12 is located inside the mounting frame 9. The upper surface of the driving block 12 is threadedly connected to the threaded rod 10. Positioning bolts 13 are threadedly connected to the outer walls of both sides of the cable tray body 1. The positioning bolts 13 pass through the outer walls of the cable tray body 1 and extend into the interior of the cable tray body 1. Several positioning holes for insertion of the positioning bolts 13 are opened on the outer walls of both slides 2.
[0025] By setting up the cable tray body 1, slide 2, connecting rod 3, cover 4, connecting block 5, mounting bracket 6, locking block 7, locking groove 8, mounting frame 9, threaded rod 10, turntable 11, driving block 12 and positioning bolt 13, the function of expanding the cable tray is realized. By setting the slide 2 on the inner wall of the cable tray body 1, the cable tray is expanded when the slide 2 drives the cover 4 to slide upward along the inner wall of the cable tray body 1, thereby making the use of the cable tray more convenient and improving its practicality.
[0026] The inner wall of the cover 4 is provided with a fixing assembly, which includes a bidirectional lead screw 14. The bidirectional lead screw 14 is rotatably connected to the top wall of the middle position of the cover 4 via a mounting plate. Slide rods 15 are fixedly installed on the top walls of the cover 4 near both ends via fixing plates. Movable plates 16 are fitted on the outer surfaces of both ends of the slide rods 15. Positioning plates 17 are fixedly installed on the opposite side walls of the two movable plates 16. The outer surface of the bidirectional lead screw 14 has forward threads and reverse threads. The two movable plates 16 are respectively threaded to the two ends of the bidirectional lead screw 14. Next, the positioning plates 17 on the side walls of the two movable plates 16 are respectively inserted into the inner walls of the two slides 2. The upper surface of the cover 4 is rotatably connected to a rotating rod 18 that passes through the cover 4. A rotating plate 19 is fixedly installed at the top of the rotating rod 18, and a bevel gear A20 is fixedly installed at the bottom of the rotating rod 18. A bevel gear B21 is fixedly installed on the outer surface of the double-acting screw 14. The bevel gear A20 and the bevel gear B21 mesh. A fixing bolt 22 that passes through the rotating plate 19 is threadedly connected to the upper surface of the rotating plate 19. The fixing bolt 22 is inserted into the upper surface of the cover 4.
[0027] By setting up a bidirectional lead screw 14, a slide bar 15, a movable plate 16, a positioning plate 17, a rotating rod 18, a rotating plate 19, a bevel gear A20, a bevel gear B21, and a fixing bolt 22, the function of conveniently and quickly fixing the cover 4 is realized. By setting up bevel gears A20 and B21, the rotating rod 18 rotates, driving the bidirectional lead screw 14 to rotate, thereby causing the movable plate 16 to drive the positioning plate 17 to move. When the positioning plate 17 is inserted into the inner wall of the two slides 2, the cover 4 is fixed, saving time and effort and improving the assembly efficiency of the cable tray.
[0028] Working principle: Before using the cable tray, assemble the cable tray by placing the cover 4 above the main body 1 and the slide 2, aligning the two slides 2 with the cover 4 and the connecting block 5 with the connecting groove. Lower the cover 4 so that it fits onto the top of the two slides 2, and the connecting block 5 slides into the connecting groove. When the upper surface of the slide 2 contacts the inner wall of the cover 4, rotate the rotating plate 19. When the rotating plate 19 rotates, it drives the rotating rod 18 to rotate. During the rotation of the rotating rod 18, the bevel gear A20 drives the bevel gear B21 to rotate, thereby enabling bidirectional rotation. When the lead screw 14 rotates, it drives the two movable plates 16 to move. Under the action of the slide rod 15, the two movable plates 16 slide along the outer surface of the slide rod 15 from the middle position of the double-sided lead screw 14 to both ends of the double-sided lead screw 14. At the same time, it drives the positioning plate 17 to move closer to the two slides 2. When the positioning plate 17 on the side wall of the two movable plates 16 is inserted into the inner wall of the slide 2, the cover 4 is fixed, thus completing the assembly of the cable tray. Then, the cable tray can be installed by using the mounting bracket 6 on the upper surface of the cover 4 with bolts.
[0029] When the cable tray needs to be expanded, first loosen the four positioning bolts 13 so that the positioning bolts 13 extend away from the main body 1 of the cable tray. After the positioning bolts 13 slide out of the positioning holes, the fixation of the slide 2 is released. Then rotate the turntable 11. When the turntable 11 rotates, it drives the threaded rod 10 to rotate inside the mounting frame 9. During the rotation of the threaded rod 10, it drives the driving block 12 to move. Under the action of the front slide 2, the locking block 7 and the locking groove 8, the driving block 12 drives the front slide 2 to slide upward inside the main body 1 of the cable tray. During the movement of the front slide 2, the connecting rod 3 drives the rear slide 2 to slide upward, thereby driving the cover 4 to move upward, thus expanding the cable tray. After the cable tray is expanded, stop rotating the turntable 19 and loosen the positioning bolts 13 in the opposite direction so that the positioning bolts 13 re-enter the positioning holes and fix the two slides 2.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
