Description

Technical Field

[0001] This utility model relates to the field of cable support technology, specifically a low-voltage cable support device applied in subway tunnels. Background Technology

[0002] Subways have enriched people's travel options, alleviated the pressure of ground traffic congestion, saved people travel time, and allowed them to better enjoy life. Subways run in tunnels, and the low-voltage cables in subway tunnels are usually laid on the outer wall of the tunnel and hung on cable brackets. The safety and stability of communication, signal and other low-voltage cables are particularly important for subway operation.

[0003] Existing low-voltage cable supports in subway tunnels are generally fixed rods on the wall with several crossbars. The cables are placed on the crossbars. Because the cables are relatively thick, they can easily slip off the crossbars when they encounter corners in the wall. Therefore, it is necessary to design a low-voltage cable support device for use in subway tunnels. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model designs a low-voltage cable support device for use in subway tunnels, which solves the technical problem that cables placed on horizontal bars easily slip off the support when encountering wall corners.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage cable support device for use in subway tunnels, comprising a mounting base, which is fixed to a wall by screws. The mounting base is U-shaped and has a round rod on it. The round rod is rotatably connected to a support assembly, which includes a crossbar. One end of the crossbar has a positioning hole, the size of which corresponds to the diameter of the round rod. The crossbar can rotate left and right around the round rod, and a support block is provided on the round rod.

[0006] Furthermore, a snap-fit ​​bracket is provided at the end of the crossbar away from the round bar, and a telescopic groove is provided inside the snap-fit ​​bracket. A return spring is fixedly connected to the inner wall of the telescopic groove, and a snap-fit ​​block is fixedly connected to the end of the return spring away from the telescopic groove. A limit frame is hinged inside the snap-fit ​​bracket.

[0007] Furthermore, the limiting frame has a U-shaped structure design, and a locking hole is provided at the position corresponding to the locking block. The limiting frame and the locking frame are hinged to rotate, and the locking block is locked to the limiting frame through the locking hole.

[0008] Furthermore, the crossbar is provided with binding holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model uses screws to fix the mounting base to the wall. The crossbar can rotate left and right around the round rod, which facilitates the adjustment of the angle of the bracket assembly, improves the flexibility and adjustability of the entire bracket, and can meet the needs of different cable installation conditions. It is convenient for cable installation and use. The crossbar can provide support for the cable. The limiting frame and the snap-fit ​​frame are hinged and rotate. The return spring drives the snap-fit ​​block to engage with the snap-fit ​​frame through its own elasticity, which facilitates the limiting of the cable placed on the bracket and prevents the cable from sliding and falling off the bracket.
