[0002] Cable tray is a kind of equipment specially used to support and protect cables, usually composed of brackets, brackets and installation accessories. Its main function is to provide support, protection and organization management for cables, so that cables can be laid on the tray safely and orderly. Cable trays have various structural forms, including trough type, tray type, ladder type and grid type, etc. The appropriate structural form can be selected according to different needs and application scenarios. During design and construction, factors such as the material, specification, and anti-corrosion treatment of the cable tray also need to be considered to ensure that it can adapt to different environments and conditions.

[0003] At present, in the design and use of cable trays, in order to ensure the neatness and convenience of maintenance of cables, some limiting measures are usually required to prevent the cables from moving or entangled at will inside the cable tray. Cable clips or cable ties are generally used to bundle and limit the cables. Although cable clips or cable ties have an effective limiting effect and improve the protection performance of cables, due to the long length and large number of cables, it takes a lot of time to limit and bundle the cables in multiple places, which affects work efficiency. Therefore, a cable tray is proposed. Utility Model Content

The counterweight block 8 is clamped in the inside of the limit frame 9 and is of a suitable size. Two clamping seats 10 are fixedly installed on the top outer wall of the pressure plate 7, and two connecting ropes 11 are fixedly installed on the top inner wall of the cover plate 2. A hook 12 is fixedly installed on the bottom outer wall of the connecting rope 11, and the hook 12 is clamped on the outer wall of the clamping seat 10. The upper limit seat 5 and the lower limit seat 6 have the same shape and are semi-circular. The upper and lower adjacent upper limit seats 5 and lower limit seats 6 form a limiting ring.

[0025] An adjusting rod 13 is rotatably connected to the top outer wall of the pressure plate 7, a threaded hole is provided inside the cover plate 2, a threaded groove is provided on the outer peripheral wall of the adjusting rod 13, the adjusting rod 13 is threadedly connected to the inside of the threaded hole and the size is adapted, a limiting clamping seat 14 is movably installed inside the adjusting rod 13, a limiting groove is provided on the top of the cover plate 2, the limiting groove is connected to the threaded hole, the size of the limiting groove is adapted to the size of the limiting clamping seat 14, a through hole is provided inside the adjusting rod 13, the limiting clamping seat 14 is slidably connected to the inside of the through hole and the size is adapted.

[0026] In this embodiment, the cover plate 2 is slidably connected between the left and right outer walls of the cable tray body 1, and the cover plate 2 is attached to the top outer wall of the cable tray body 1.

[0027] In this embodiment, ventilation holes are provided on the inner walls on both sides of the cable tray body 1 .

[0028] In this embodiment, the adjustment plate 3 is fixed after being moved upward through the action of the base 10, the connecting rope 11 and the hook 12.

[0031] The working principle of the above embodiment is:

[0032] First, place the organized cables inside the lower limit seat 6. At this time, the staff separates the hook 12 from the seat 10. At this time, the staff turns the adjusting rod 13. Since part of the outer peripheral wall of the adjusting rod 13 is threadedly connected to the top of the cover plate 2, the adjusting rod 13 will move downward. At this time, the adjusting plate 3 and the pressure plate 7 move downward synchronously. When the threaded groove opened by the adjusting rod 13 is not threadedly connected to the cover plate 2, the upper limit seat 5 is driven downward by the gravity of the counterweight block 8. At this time, you only need to slowly move the adjusting rod 13 downward. At this time, the limit seat 14 will be stuck into the top inner wall of the cover plate 2 to limit the cover plate 2. When the upper limit seat 5 and the lower limit seat 6 are fitted, the cable limiting work is completed.
