[0002] Cable trays are tools for managing and organizing cables and some conduits, allowing numerous cables within a building to be arranged neatly and orderly. They also support a large number of cables, making the appearance of a complex network of cables more aesthetically pleasing. Cable trays come in various structures, including trough type, tray type, ladder type, and mesh type. They consist of supports, brackets, and installation accessories. Cable trays can be installed independently within a building or attached to various building structures and pipe rack supports. They should feature simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized.

[0003] Because cable trays have limited length, multiple cable trays need to be connected and installed together. Cable tray connecting plates and bolts are used to fix the trays at the ends that need to be connected. This installation method requires a large number of bolts for tightening, resulting in a large workload and reduced installation efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick-connection structure for cable trays. This solves the problem that using cable tray connecting pieces and bolts for fixing at the ends of the cable trays that need to be connected requires a large number of bolts for tightening, resulting in a large workload and reduced installation efficiency.

[0023] Example

[0024] This utility model provides a quick-connection structure for cable trays, see reference. Figure 1-4 As shown, the cable tray includes a cable tray body, which includes a cable tray base plate 1. One end of the cable tray base plate 1 is provided with a bearing plate 3 integrally formed therewith. The bearing plate 3 has a first fixing hole 6 through which a fixing bolt is inserted. The other end of the cable tray base plate 1 is provided with a bearing groove 9 for the bearing plate 3 to be inserted. Cable tray side plates 2 are symmetrically provided on both sides of the cable tray base plate 1.

[0025] One end of the cable tray side plate 2 is provided with a docking plate 4. A first fastening groove 5 is provided on the outer end face of the docking plate 4. The other end of the cable tray side plate 2 is provided with a docking groove 8 for the docking plate 4 on the adjacent cable tray body to be inserted. A second fastening groove 13 is provided on the outer wall of the cable tray side plate 2 on both the upper and lower sides of the docking groove 8, which is connected to the first fastening groove 5. The second fastening groove 13 is connected to the docking groove 8.

[0026] The length of the support plate 3 is greater than the length of the docking plate 4. During the docking installation of the two cable tray bodies, the support plate 3 will contact the other cable tray body before the docking plate 4. After the support plate 3 is inserted into the support groove 9, the docking plate 4 can be smoothly inserted into the docking groove 8 without the need for additional alignment of the docking plate 4 with the docking groove 8. This facilitates the docking installation of the two cable tray bodies by the workers, improving installation efficiency.

[0027] The cable tray base plate 1 has a second fixing hole that communicates with the first fixing hole 6. Below the cable tray base plate 1 is a drive plate 10 with a long rectangular structure. The drive plate 10 enables the two connecting plates 7 to move synchronously. The drive plate 10 has a third fixing hole 11 that communicates with the second fixing hole. Connecting plates 7 are symmetrically located on both sides of the drive plate 10, on the outer sides of the cable tray side plates 2. The use of the first fixing hole 6, the second fixing hole, and the third fixing hole 11, along with fixing bolts, improves the connection strength and stability between the two adjacent cable tray bodies, preventing displacement of the drive plate 10 and thus avoiding the fastening plate 15 from detaching from the first fastening groove 5 and the second fastening groove 13.

[0028] Furthermore, a guide block 14 is provided on the inner end face of the connecting plate 7, and a guide groove 12 is provided on the outer wall of the cable tray side plate 2 to allow the guide block 14 to move. Through the arrangement of the guide block 14 and the guide groove 12, the connecting plate 7 can be moved along a preset path without detaching from the connection with the cable tray body, while ensuring that the fastening plate 15 can be inserted into the connected first fastening groove 5 and second fastening groove 13.

[0029] When the guide block 14 moves to the top of the guide groove 12, the top end face of the drive plate 10 fits against the bottom end face of the cable tray base plate 1, so that the fixing bolts can be inserted into the second fixing hole and the third fixing hole 11, thereby fixing the drive plate 10 stored at the bottom of the cable tray body, which is convenient for workers to transport and move the cable tray body. When the guide block 14 moves to the bottom of the guide groove 12, the drive plate 10 drives the two connecting plates 7 to move synchronously, so that the fastening plate 15 is removed from the docking groove 8, so that the subsequent docking plate 4 can be inserted into the docking groove 8.

[0030] Furthermore, the top end face of the drive plate 10 is provided with a fastening plate 15 that can be inserted into the connected first fastening groove 5 and second fastening groove 13. By using the fastening plate 15 in conjunction with the first fastening groove 5 and the second fastening groove 13, the two cable tray bodies can be securely locked together.

[0031] The working principle and operation steps of this utility model are as follows:

[0032] In the initial state, the drive plate 10 is attached to the bottom of the cable tray base plate 1, and the fixing bolts are inserted into the second fixing hole and the third fixing hole 11. At the same time, the fastening plate 15 is located in the second fastening groove 13 and the docking groove 8.

[0033] When installing the two cable tray bodies together, first loosen the fixing bolts to disengage them from the second and third fixing holes 11, releasing the fixation from the drive plate 10. Then, the drive plate 10 drives the two connecting plates 7 to move downwards synchronously. The displacement of the connecting plates 7 causes the fastening plate 15 to exit from the docking groove 8, so that the docking plate 4 can be inserted into the docking groove 8. Next, insert the bearing plate 3 on one cable tray body into the bearing groove 9 in the other cable tray body. At this time, the first fixing hole 6 on the bearing plate 3 is connected to the second fixing hole, and the docking plate 4 moves downwards. The fastening plate 15 is inserted into the docking groove 8. At this time, the first fastening groove 5 and the second fastening groove 13 on the docking plate 4 are connected to form a continuous channel. Finally, the upward displacement drive plate 10 drives the two connecting plates 7 to move synchronously, so that the fastening plate 15 is inserted into the connected first fastening groove 5 and the second fastening groove 13. At this time, the third fixing hole 11 on the drive plate 10 is connected to the first fixing hole 6 and the second fixing hole. The fixing bolts are inserted into the connected first fixing hole 6, the second fixing hole and the third fixing hole 11 for fixing, thus completing the docking installation of the two cable tray bodies. This utility model is easy to operate, reduces the amount of bolts used, and improves the docking efficiency and load-bearing capacity of the two cable tray bodies.
