[0002] In fields such as power engineering, communication engineering, and building electrical systems, cable trays are widely used in indoor and outdoor cable laying scenarios as key components for supporting and protecting cables. Their core function is to arrange cables in an orderly manner, avoid interference or physical damage to cables from the external environment, and facilitate later maintenance and expansion.

[0003] Existing cable tray connections mostly rely on bolts, nuts, washers, and other components. When connecting, the mounting holes of the cable tray interface must be aligned first, and then the bolts must be inserted one by one and the nuts manually tightened. Some large cable trays even require the assistance of tools such as wrenches and screwdrivers. This operation is very time-consuming, labor-intensive, inconvenient, and greatly affects the progress of the project. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention connects the mounting plate to the mounting base by inserting it into a sliding groove. A first spring pushes a conical block out of the movable groove to quickly align and position the mounting plate and the mounting base. Then, the rotating shaft drives the sliding rod to move, pulling the locking pin to extend and engage in the V-shaped groove. A second spring then pulls the locking pin to move and tighten it in the V-shaped groove. The positioning block further connects the locking pin. After the locking pin is engaged in the V-shaped groove, the screw is rotated to push the abutment ring to move. The abutment ring drives the insertion pin to be inserted into the hole groove for positioning and fixation. This achieves rapid snap-fit ​​assembly of the mounting plate and the mounting base. Compared with the traditional bolt and nut connection, no tools are required, and it can be completed by hand, greatly improving the assembly speed and indirectly shortening the construction period.
