[0001] This utility model relates to the field of cable tray technology, and more specifically to a cable tray with a stable connection. Background Technology

[0002] Cable trays are a rigid structural system that closely supports cables, consisting of straight sections, bends, components, brackets, and hangers of trays or ladders. Cable trays are generally suitable for large enterprises, large-scale engineering substations, cable laying, large bridges, subway cable laying, and marine drilling. Cable trays are usually suspended at the bottom of the ceiling of a building.

[0003] The existing cable tray connectors are metal sheets that are bolted to the cable tray. This connection method requires multiple sets of bolts, which makes the installation process time-consuming for workers. Furthermore, the cable tray is not stable and has insufficient strength after installation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a stable cable tray connection. This solves the problem that existing cable tray connectors are metal sheets that are bolted to the cable tray. This connection method requires the installation of multiple sets of bolts, which causes workers to spend a lot of time during the installation process. Furthermore, the cable tray is not stable and has insufficient strength after installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sturdy cable tray includes a cable tray body and a fixing mechanism and a connecting mechanism disposed at the connection between two adjacent cable tray bodies. The cable tray body includes a cable tray base plate. A first mating block is provided on one side of the bottom end face of the cable tray base plate, and a second mating block is provided on the other side of the bottom end face of the cable tray base plate. The second mating block is a trapezoidal insertion block that fits into the first mating block on the adjacent cable tray body. Cable tray side plates are symmetrically provided on both sides of the cable tray base plate.

[0007] The fixing mechanism includes a baffle, and a mounting plate perpendicular to the baffle is provided on one side of the bottom. A plug-in groove adapted to the plug-in block is opened on the top end face of the mounting plate. Two opposing support plates are provided on the side of the mounting plate away from the baffle. A fastening groove is opened through the support plate. A first locking half-post is provided on the bottom end face of the support plate on the side of the fastening groove. A connecting threaded post is provided at the end of the first locking half-post away from the support plate. A locking nut is screwed onto the connecting threaded post.

[0008] As a preferred technical solution of this utility model, multiple limiting blocks are provided at both ends of the outer side wall of a cable tray side plate, and a limiting groove is provided through the baffle plate for the limiting blocks to engage when two adjacent cable tray bodies are connected end to end.

[0009] By using the above technical solution and the setting of the limiting block and the limiting groove, the connection strength between the fixing mechanism and the cable tray body is improved.

[0010] As a preferred technical solution of this utility model, the connecting mechanism includes a connecting plate, and two fastening rods that can be inserted into the fastening groove when the two adjacent cable tray bodies are connected end to end are symmetrically provided on both sides of the bottom end face of the connecting plate. The bottom of the fastening rod is provided with a second locking half column that cooperates with the first locking half column.

[0011] Through the above technical solution, the connection between the connecting mechanism and the fixing mechanism can be limited by the setting of the fastening rod and the fastening groove, and the connection between the connecting mechanism and the fixing mechanism can be fixed by the cooperating setting of the first locking half column and the second locking half column.

[0012] As a preferred technical solution of this utility model, guide plates are provided at both ends of the outer side wall of the other cable tray side plate, and guide grooves are provided on the inner side wall of the connecting plate for the guide plates to be inserted when the two adjacent cable tray bodies are connected end to end.

[0013] The above technical solution improves the connection strength between the connection mechanism and the cable tray body by using the guide plate and guide groove.

[0014] As a preferred technical solution of this utility model, a positioning groove is provided at one end of the cable tray side plate, and a positioning rod that can be inserted into the positioning groove is provided at the other end of the cable tray side plate.

[0015] The above technical solution utilizes the positioning groove and positioning rod to provide guidance for the installation between two adjacent cable tray bodies.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] During installation, firstly, align the positioning rod on one cable tray body with the positioning groove on the other cable tray body and insert them to initially fix the two adjacent cable tray bodies together. At this time, the first mating block and the second mating block on the two adjacent cable tray bodies fit together to form a trapezoidal insertion block. Then, align the insertion groove on the fixing mechanism with the insertion block at the connection point of the two adjacent cable tray bodies and insert them. When the insertion block is inserted to the bottom of the insertion groove, the limiting blocks on the two adjacent cable tray bodies will engage with the limiting groove on the baffle, thus installing the fixing mechanism between the two adjacent cable tray bodies. Then, the guide groove on the connecting plate is aligned with the guide plates on the two adjacent cable tray bodies and inserted, so that the fastening rod at the bottom of the connecting plate passes through the fastening groove on the fixing mechanism, and the second locking half-post is located on the outer side of the bottom of the support plate and fits against the first locking half-post. Finally, the locking nut on the connecting threaded post is turned to move it, so that the locking nut moves onto the fitted first and second locking half-posts for fixing, thereby fixing the connection mechanism between the two adjacent cable tray bodies and the connection with the fixing mechanism, thus completing the docking installation between the two adjacent cable tray bodies. This utility model facilitates the docking installation of two adjacent cable tray bodies by workers, and at the same time improves the connection strength and stability between the two adjacent cable tray bodies.
