Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, and specifically relates to a corner connection device for cable trays. Background Technology

[0002] Cable trays are standardized, serialized, and universal engineering components used to support, protect, and orderly lay wires, cables, and conduits. They are widely used in construction, power, and communication industries. During the installation of cable tray systems, corner connection devices are key components that allow adjacent trays to change direction horizontally or vertically (usually at a 90-degree angle). Their performance directly affects the stability, safety, and service life of the entire cable tray system.

[0003] Currently, common corner connectors in existing technologies have relatively simple structures but low structural strength. Because the two ends of the corner connector are subjected to external forces from the cable tray, they are prone to deformation, which affects the assembly effect. Therefore, it is necessary to design a corner connector for cable trays to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a corner connection device for cable trays to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a corner connection device for cable trays, comprising a cable tray corner connector, wherein a reinforcing component is installed inside the cable tray corner connector, and a supporting component is installed inside the cable tray corner connector;

[0006] The reinforcement assembly includes a reinforcement base installed inside the corner connector of the cable tray, a hollow tube fixedly connected inside the reinforcement base, and countersunk screw holes formed on the surface of the reinforcement base.

[0007] Preferably, the countersunk screw hole corresponds to the hollow tube, and the countersunk screw hole extends to the bottom of the reinforcing base.

[0008] Preferably, the inner bottom of the cable tray corner connector is provided with a threaded groove, and the threaded groove corresponds to the countersunk screw hole on the surface of the reinforcing base.

[0009] Preferably, the support assembly includes a limiting frame welded to the inner wall of the cable tray corner connector, and a positioning seat is inserted inside the limiting frame.

[0010] Preferably, a support rod is fixedly connected between the two sets of positioning seats, and the surface of the support rod is provided with weight reduction holes.

[0011] Preferably, the surface of the cable tray corner connector is welded with a traction frame, and the surface of the traction frame is provided with traction holes and mounting holes.

[0012] Preferably, the inside of the cable tray corner connector is fixedly connected to a mounting plate by bolts, the bottom end of the mounting plate is fixedly connected to a mounting bracket, and the surface of the mounting bracket is rotatably connected to a guide roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Cable tray corner connectors are used to connect cable trays at right-angle bends in adjacent locations. A reinforcing base is placed inside the cable tray corner connector, with the threaded groove corresponding to the countersunk screw hole on the surface of the reinforcing base. An extension bolt is used to penetrate the reinforcing base and screw into the countersunk screw hole to complete the assembly and fixation, improving the structural strength of the cable tray corner connector. A limiting bracket is welded to the inner wall of the cable tray corner connector. Holding the support rod, the positioning seats at both ends are engaged inside the limiting bracket, further improving structural strength.

[0015] 2. The traction frame facilitates the handling and movement of the cable tray corner connector.
