Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray. Background Technology
[0002] Cable trays are commonly used for laying cables. Most existing cable trays are integral, trough-type structures, which offer good protection and are easy to install. However, single-layer cable trays can easily become tangled when there are many cables, and they also have poor heat dissipation. Therefore, multi-layer cable trays have emerged. While multi-layer cable trays can solve the problem of carrying multiple cables, their hierarchical structure and the obstruction of upper partitions make maintenance of lower-layer cables inconvenient, resulting in low practicality. Utility Model Content
[0003] The purpose of this utility model is to provide a cable tray that solves the problem that the upper partition of the existing multi-layer cable tray makes it inconvenient to maintain the lower layer cables.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A cable tray includes a top plate with a connecting plate. A mounting arm is located at the center of the lower end of the top plate. Multiple rows of mounting holes are spaced apart on the mounting arm, and multiple support arms are spaced apart on each row of mounting holes. Each support arm includes a downwardly inclined arm, and multiple cable dividers are located at the upper end of the inclined arm. A base plate is detachably provided at the lower end of the mounting arm. Side protective plates adapted to the support arms are hung on both sides of the top plate. Connecting holes are provided at both ends of the top plate and the base plate.
[0006] Furthermore, multiple hanging posts are provided on both sides of the upper end of the top plate. The side protective plate includes a horizontal part and a vertical part, and the horizontal part has through holes adapted to the hanging posts.

[0024] like Figure 1-3 As shown, one embodiment of this utility model is as follows:
[0025] A cable tray includes a top plate 1, a connecting plate 2 on the top plate 1, a mounting arm 3 at the lower center of the top plate 1, multiple rows of mounting holes 4 spaced apart on the mounting arm 3, and multiple support arms 5 spaced apart on each row of mounting holes. Each support arm 5 includes a downwardly inclined arm 53, and multiple cable dividers 55 are provided at the upper end of the inclined arm 53. A base plate 6 is detachably provided at the lower end of the mounting arm 3. Side protective plates 7 adapted to the support arms 5 are hung on both sides of the top plate 1. Both ends of the top plate 1 and the base plate 6 are provided with connecting holes 8.
[0026] The connection hole 8 is used for connecting adjacent cable trays. Specifically, since the frame structure of the cable trays is the same, adjacent cable trays cannot be directly connected. Therefore, additional connecting plates are needed to connect adjacent legs. The connecting plates are connected to the connection holes on the top / bottom plates of the adjacent cable trays to achieve the splicing and assembly of multiple devices.
[0027] The base plate 6 of this application is not used to support cables, so its thickness can be appropriately reduced to save costs. At the same time, there are gaps between its two sides and the side protective plates 7 to facilitate the installation and removal of the side protective plates 7. The connecting plates 2 on the top plate are evenly distributed, and the connecting plates 2 are provided with mounting holes for connecting hanging rods to facilitate the installation and fixing of hanging rods to the roof.
[0028] The centrally positioned mounting arm divides the cable tray into left and right installation spaces. Cable dividers further separate the cables, facilitating the categorization and routing of multiple cables and preventing tangling. Simultaneously, the inclined arm 53 allows the cables to be arranged at an angle. Combined with the quick-release structure of the side protective plate 7, removing the side protective plate leaves no obstruction between upper and lower layers of cables, facilitating cable maintenance from the side of the cable tray.
[0029] Specifically, the top plate 1 has multiple hanging posts 9 on both sides of its upper end. The side protective plate 7 includes a horizontal part and a vertical part, and the horizontal part has through holes adapted to the hanging posts 9. The through holes on the side protective plate 7, together with the hanging posts 9 on the top plate 1, allow the side protective plate 7 to be installed and fixed by directly hanging it using its own weight. The operation is simple and convenient, the connection is stable, and the assembly and disassembly efficiency is high.
[0030] In this embodiment, the support arm 5 further includes a connecting ear 51, which is threadedly connected to the mounting hole 4. The outer middle part of the connecting ear 51 is provided with a first horizontal connecting part 52, which is connected to the upper end of the inclined arm 53. The lower end of the inclined arm 53 is provided with a second horizontal connecting part 54, and the lower end of the second horizontal connecting part 54 is provided with an elastic element. The inner sidewall of the vertical part is provided with a support element adapted to the elastic element.
[0031] The elastic element includes a spring 10 and a connecting block 11. The upper end of the spring 10 is connected to the second horizontal connecting part 54, and the lower end of the spring 10 is connected to the connecting block 11. The support element includes a support bar 12, which contacts the lower end of the connecting block 11.
[0032] The spring 10, connecting block 11, and support bar 12 further ensure the stable installation of the side protective plate 7. During installation, the side protective plate 7 is moved diagonally upwards so that the horizontal part is above the top plate 1, compressing the spring 10 and aligning the hanging post 9 with the through hole. Under the reset action of the spring 10, the hanging post 9 passes through the through hole, achieving stable installation of the side protective plate 7 and effectively preventing it from falling off. When removing it, apply vertical upward force to move the side protective plate 7, disengaging the hanging post 9 from the through hole. Then, offset the side protective plate 7 so that the horizontal part crosses the top plate, allowing the side protective plate 7 to be removed. The operation is simple.
[0033] Meanwhile, the spring 10, connecting block 11, and support bar 12 also support the outer end of the bearing arm, effectively ensuring the stable support of the cable by the bearing arm 5.
[0034] To enhance the supporting force of the load-bearing arm 5, a first horizontal connecting portion 52 is disposed in the middle of the connecting ear, and a reinforcing rib 56 is provided between the connecting ear 51 and the first horizontal connecting portion 52, extending below the inclined arm 53. The reinforcing rib 56 further improves the supporting stability.
[0035] To facilitate heat dissipation, ventilation holes 13 are provided on the vertical part.
[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
