[0007] The technical solution adopted by this utility model to solve its technical problem is: a flame-retardant enclosed cable support tray, including a tray body, a top cover installed on the top of the tray body, an auxiliary module provided at the bottom of the tray body, and a cable management module installed inside the tray body; the cable management module includes a separator rod, a fixing block, an elastic band and a limiting ring, a fixing block is provided at the end of the separator rod, an elastic band is installed inside the fixing block, and a limiting ring is provided at the top of the elastic band.

[0008] Preferably, the partition rods are evenly distributed about the inner wall of the cable tray body, and the partition rods and the fixing blocks are integrated.

[0009] Preferably, the fixing block and the limiting ring are slidably connected, and the limiting ring and the elastic band are glued together.

[0010] Preferably, both the main body and the top cover of the cable tray are made of polymer material, and the main body of the cable tray is inlaid with a metal skeleton.

[0011] Preferably, the auxiliary module includes a mounting bracket, a limiting hole, a base plate, and heat sinks. The mounting bracket has a limiting hole at one end, and a base plate is provided at the bottom of the mounting bracket. Heat sinks are installed on both sides of the base plate.

[0012] Preferably, the heat sink is tightly fitted to the bridge frame body, and the heat sink is welded to the base plate.

[0013] Preferably, the base plate is designed in an I-shape, and the central axis of the base plate coincides with the central axis of the cable tray body.

[0014] The advantages of this utility model are:

[0015] 1. This utility model utilizes the combined operation of the cable tray body and the cable management module to provide cable management functionality. It allows for the categorization and arrangement of cables, making more rational use of the internal space of the cable tray body, improving space utilization, and facilitating future cable maintenance and repair. It prevents cables from piling up haphazardly, which would require maintenance personnel to spend considerable time identifying cables needing repair. The cable management module also provides a limiting effect, ensuring stable cable arrangement within a specific path and preventing displacement or entanglement caused by external forces or vibrations. This improves cable management efficiency. The cable management module is corrosion-resistant, lightweight, and non-conductive. An internal metal frame provides flame retardancy, offering high protection for internal facilities and preventing cables from being affected by the external environment, ensuring stable operation.

[0016] 2. This utility model adopts the cooperation of the mounting bracket, the base plate and the heat sink to achieve heat dissipation effect. It can absorb the heat generated inside the cable tray body and dissipate it to the external environment, preventing the internal temperature from being too high and affecting the cables. The mounting bracket can be installed and fixed, so that the cable tray body can be fixed in different positions, making the installation operation simpler. It can increase the overall strength of the cable tray body and prevent the cable tray body from deforming when subjected to external impact. Attached Figure Description

The cable management module 4 includes a separator 401, a fixing block 402, an elastic band 403, and a limiting ring 404. The end of the separator 401 is provided with a fixing block 402, and the inside of the fixing block 402 is provided with an elastic band 403. The top of the elastic band 403 is provided with a limiting ring 404. The separator 401 is evenly distributed around the inner wall of the tray body 1, and the separator 401 and the fixing block 402 are integrated. Through this design, it has a cable management function, which can classify and arrange the cables, making more reasonable use of the internal space of the tray body 1, improving space utilization, and facilitating later maintenance and repair of the cables. It also prevents the cables from piling up randomly, which would require maintenance personnel to spend a lot of time identifying the cables that need repair.

[0026] Please see Figure 4 As shown, the fixing block 402 and the limiting ring 404 are slidably connected, and the limiting ring 404 and the elastic band 403 are glued together. This setting has a limiting effect on the cable, ensuring that the cable is stably arranged in a specific path, avoiding displacement, tangling and other problems caused by external force or vibration, and improving the cable management effect.

[0027] Please see Figures 1 to 2 As shown, both the main body 1 and the top cover 2 of the cable tray are made of polymer material, and the main body 1 of the cable tray is inlaid with a metal skeleton. With this design, it has the characteristics of corrosion resistance, light weight and non-conductivity. The inlaid metal skeleton can play a flame-retardant role and has a high protection effect on the internal facilities, preventing the internal cables from being affected by the external environment and ensuring their stable operation.

[0028] Please see Figures 1 to 2 As shown, the auxiliary module 3 includes a mounting bracket 301, a limiting hole 302, a base plate 303, and a heat sink 304. The mounting bracket 301 has a limiting hole 302 pre-drilled at its end, and a base plate 303 is provided at the bottom of the mounting bracket 301. Heat sinks 304 are installed on both sides of the base plate 303. The heat sinks 304 are tightly fitted to the cable tray body 1, and the heat sinks 304 are welded to the base plate 303. This arrangement has a heat dissipation effect, which can absorb the heat generated inside the cable tray body 1 and dissipate it to the external environment, preventing the internal temperature from being too high and affecting the cables. The mounting bracket 301 can be installed and fixed, so that the cable tray body 1 can be fixed in different positions, making the installation operation simpler.

[0029] Please see Figure 2As shown, the base plate 303 is designed in an I-shape, and the central axis of the base plate 303 coincides with the central axis of the cable tray body 1. This design can increase the overall strength of the cable tray body 1 and prevent the cable tray body 1 from deforming when subjected to external impact.

[0030] Working principle: First, lift the limiting ring 404 upward to increase the space below the limiting ring 404. Then, pass the cable through the limiting ring 404, release the limiting ring 404, and under the elastic force of the elastic band 403, pull the limiting ring 404 downward to limit the cable. According to the characteristics of the cable, different cables are classified and placed in different separator bars 401. Then, insert the top cover 2 and move the cable tray body 1 to the required position. Fix the mounting bracket 301 by connecting the limiting hole 302 with bolts, thereby fixing the cable tray body 1 to the installation position.
