However, it requires a lot of bolts, the operation is more cumbersome, increases the workload of operators, and affects the installation efficiency.

[0004] Therefore, it is necessary to propose a high-strength, corrosion-resistant cable tray to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, corrosion-resistant cable tray to solve the problems of using a large number of bolts, making the operation cumbersome, increasing the workload of operators, and affecting installation efficiency.

The connecting component includes a bracket, wherein two brackets are provided, each bracket being inverted L-shaped and symmetrically distributed. The two ends of the top lower surface of the bracket are respectively attached to the two tray bodies, and each end of the top lower surface of the bracket is fixedly connected to a plug. The top of each of the two tray bodies is provided with a plug hole that mates with the corresponding plug. The two brackets are fixed together by a locking component.

[0007] Preferably, the locking assembly includes a sliding plate, a square groove, a threaded rod, and a threaded cylinder. There are two of each of the sliding plate, the square groove, and the threaded rod.

[0012] Preferably, the top of the fixing plate is provided with a limiting groove, and the limiting groove is provided in multiple ways and the multiple limiting grooves are evenly distributed.

[0013] The technical effects and advantages of this utility model are as follows:

[0022] This utility model provides, for example Figures 1-4 The high-strength corrosion-resistant cable tray shown includes a cable tray body 1, and multiple cable tray bodies 1 are provided. The surface of the cable tray body 1 is provided with an anti-corrosion coating. The anti-corrosion coating can be, but is not limited to, epoxy resin coating. Since the surface of the cable tray body 1 is exposed to the air for a long time, the surface of the cable tray body 1 is prone to oxidation and corrosion when in contact with the air. The anti-corrosion layer can slow down the rate of corrosion of the cable tray body 1 by the air, thereby increasing the service life of the cable tray body 1.

[0023] Considering that in existing technology, adjacent cable tray bodies 1 are typically fixed together using side plates and bolts, the bolts may loosen when the weight on the cable tray body 1 is excessive, leading to misalignment between the two adjacent cable tray bodies 1 and affecting the safety of the cable tray, this utility model provides a connecting component between each of the two adjacent cable tray bodies 1 to improve the stability and convenience of the connection. The connecting component includes two clips 2, which are inverted L-shaped and symmetrically distributed. The two ends of the lower top surface of the clips 2 are respectively attached to the two cable tray bodies 1. A reinforcing strip 11 is fixedly connected to the top of the clip 2 near the inside of the cable tray body 1, and the reinforcing strip 11 is attached to the inner wall of the cable tray body 1. The reinforcing strip 11 and the top of the clip 2 form an inverted U-shaped structure and are engaged with the top of the cable tray body 1, preventing the two adjacent cable tray bodies 1 from misaligning along their width direction.

[0024] Both ends of the top lower surface of the cable tray 2 are fixedly connected to insert blocks 4, and the top of each of the two cable tray bodies 1 is provided with insertion holes 3 that mate with the corresponding insert blocks 4. The insertion holes 3 and insert blocks 4 are provided to prevent two adjacent cable tray bodies 1 from separating along their length.

[0025] The two card holders 2 are fixed together by a locking assembly, which includes a sliding plate 6, a square groove 7, a threaded rod 8, and a threaded cylinder 9. Two sliding plates 6, two square grooves 7, and two threaded rods 8 are provided. The square groove 7 is formed on the sliding plate 6, and the sliding plate 6 is slidably mounted on the corresponding card holder 2 via the square groove 7. Two threaded rods 8 are respectively fixedly connected to the adjacent surfaces of the two sliding plates 6, and the two ends of the threaded cylinder 9 are threadedly engaged with the two threaded rods 8.

[0026] Specifically, the operator places the two clips 2 on both sides of the docking position of the two adjacent cable tray bodies 1, inserts the plug 4 into the corresponding plug hole 3, and then pushes the slide plate 6 to make it fit against the bottom of the cable tray body 1. Then, the operator rotates the threaded cylinder 9 to drive the two threaded rods 8 to move towards each other, so that the two clips 2 move towards each other, completing the docking and fixing of the two adjacent cable tray bodies 1 and forming a fixed frame structure. At the same time, positioning is performed from the top, bottom and sides of the docking position of the two adjacent cable tray bodies 1, increasing the connection strength between the two adjacent cable tray bodies 1. The operation is convenient and improves the stability and convenience of cable tray docking.

[0027] To facilitate the rotation of the threaded cylinder 9, a rotating sleeve 10 is fixedly connected to the outside of the threaded cylinder 9. The rotating sleeve 10 can be configured with the same structure as the nut, and its outer wall is a regular hexagon.

[0028] The bottom of the card holder 2 is fixedly connected to a limiting plate 5. The length and width of the limiting plate 5 are larger than the length and width of the square groove 7. The limiting plate 5 is set so that the slide plate 6 will not slide out of the card holder 2. Before the cable tray is installed, there is no need to assemble the card holder 2, slide plate 6, etc., which facilitates quick docking and installation.

[0029] Considering that cables inside cable trays are usually bundled together in clusters, this can lead to poor heat dissipation and potentially cause fires. Furthermore, electromagnetic interference between multiple cables can affect communication. Therefore, this invention incorporates multiple fixing plates 12 evenly distributed inside the main body 1 of the cable tray. Each fixing plate 12 has a limiting groove 13 evenly distributed on its top. Specifically, embedding the cables into the limiting grooves 13 allows for independent placement of multiple cables, preventing electromagnetic interference and improving heat dissipation.

[0030] In practical use, a limiting rubber block or other structure can be set inside the limiting groove 13 to limit the cable embedded in the limiting groove 13.
