High-performance cable tray connectors play a crucial role in ensuring the efficient construction and long-term stable operation of cable tray systems.
[0003] Currently, traditional cable tray connectors mostly use bolt and nut fastening or snap-fit connections in terms of mechanical structure. Bolt and nut connections achieve the connection by screwing the nut onto the bolt, making the connector fit tightly against the cable tray; snap-fit connections utilize a flexible snap-fit structure to clamp the cable tray components together. The technical principle of these connection methods is mainly based on mechanical fastening force, maintaining the stability of the connection by increasing friction or mechanical interlocking force.
[0004] However, existing traditional cable tray connectors have some drawbacks. In actual installation and maintenance, connection and disassembly are inconvenient. For example, with bolt-nut connections, installation requires workers to manually tighten each nut individually, consuming a significant amount of time and manpower, and is extremely difficult to perform in confined spaces. Disassembly also requires considerable effort to unscrew the nuts, especially when they are rusted or tightened due to long-term stress. This affects work efficiency, leads to longer construction periods, and increases maintenance costs. Utility Model Content

[0025] The connecting assembly includes a second connecting rod 9, one end of which is fixedly connected to the outer wall of the second support plate 2, and the other end of which is fixedly connected to a fixing box 5. One end of the first connecting rod 3 is fixedly connected to a fixing block 4. A pushing block 12 is fixedly connected to the outer wall of the fixing box 5. The pushing block 12 slides smoothly in the first sliding groove 14. A sliding column 11 is slidably connected to the inner wall of the pushing block 12 for fixing the connection. A spring 13 is sleeved on the outer wall of the sliding column 11. A fixing column 10 is fixedly connected to the outer wall of the pushing block 12. The first sliding groove 14 is opened on the outer wall of the fixing box 5.
[0026] Specifically, when connecting the cable tray, first connect the fixing box 5 to the fixing block 4, then push the push block 12. The push block 12 slides smoothly in the sliding groove 14. During this process, the spring 13 is compressed, and at the same time, the fixing post 10 is pushed so that it is inserted into the fixing block 4. This achieves a stable connection between the support plate 1 and the support plate 2. When disassembly is required, simply push the push block 12 in the opposite direction. The spring 13 is compressed, and the fixing post 10 is pulled out from the fixing block 4.
[0027] Reference Figure 1 and Figure 3 The fixing component includes a threaded rod 17. When the threaded rod 17 rotates, it causes the movable block 19 to slide within the sliding groove 15. The outer wall of the threaded rod 17 is threadedly connected to the inner wall of the support plate 1. One end of the threaded rod 17 is fixedly connected to a switch 16, which drives the threaded rod 17 to rotate. The outer wall of the switch 16 is threadedly connected to the movable block 19. The inner wall of the movable block 19 is slidably connected to a guide rod 18. The outer wall of the support plate 1 has a sliding groove 15. The outer wall of the movable block 19 is fixedly connected to a clamping plate 6. The inner wall of the clamping plate 6 is slidably connected to a telescopic plate 7. The surface of the telescopic plate 7 has a fixing hole 8. The outer wall of the movable block 19 is slidably connected to the sliding groove 15. Inside slot 2 15, the moving block 19 is used to drive the clamping plate 6 to slide. The lower surface of the clamping plate 6 is slidably connected to the upper surface of the support plate 1. The clamping plate 6 is used to fix the cable bridge. The two ends of the guide rod 18 are fixedly connected inside the support plate 1. The guide rod 18 is used to guide the movement of the moving block 19. The outer wall of the pushing block 12 is slidably connected inside the sliding slot 14. The pushing block 12 is used to compress the spring 13. One end of the spring 13 is fixedly connected to the outer wall of the pushing block 12. The spring 13 is used to push the pushing block 12. The outer wall of the fixing column 10 is slidably connected inside the fixing block 4. The fixing column 10 is used to connect the support plate 1 and the support plate 2.
[0028] Specifically, when it is necessary to fix the cable bridge, turn the switch 16. The switch 16 drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the inner wall of the support plate 1, the rotation of the threaded rod 17 causes the moving block 19 to slide in the sliding groove 15. The guide rod 18 guides the moving direction of the moving block 19. The moving block 19 then drives the clamping plate 6 to slide. The clamping plate 6 is used to fix the cable bridge. At the same time, the telescopic plate 7 on the inner wall of the clamping plate 6 can be adjusted according to actual needs.
[0029] Working principle: When a cable tray connector is needed, the fixing box 5 and fixing block 4 are connected, and the pushing block 12 is pushed. The pushing block 12 slides in the sliding groove 14 and compresses the spring 13. At the same time, the fixing post 10 is pushed, so that the fixing post 10 is inserted into the fixing block 4, thereby connecting the support plate 1 and the support plate 2. When disassembly is required, the pushing block 12 is pushed in the opposite direction to compress the spring 13, so that the fixing post 10 can be pulled out from the fixing block 4. In addition, turning the switch 16 drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, the moving block 19 slides in the sliding groove 15. The guide rod 18 guides the movement of the moving block 19. The moving block 19 drives the clamping plate 6 to slide. The clamping plate 6 is used to fix the cable tray. At the same time, the telescopic plate 7 on the inner wall of the clamping plate 6 adapts to cable trays of different heights. The fixing hole 8 can be connected to the upper end of the cable tray with screws.
