[0002] In subway construction, leaky cables are an important way to propagate wireless signals, used for the coverage and transmission of subway wireless systems. Leaky cables are mainly used for communication and signal transmission between subway vehicles, between vehicles and stations, and between stations. The equipment installed on subway vehicles (such as on-board radio stations, communication equipment, etc.) is connected to the ground base station through leaky cables to achieve signal transmission and communication. This method can effectively cover subway vehicles and stations and provide reliable communication and signal transmission.

[0003] However, the above practicality still has shortcomings:

In subway construction, the walls of the elevated station platform area are too low to meet the height requirements for the installation of the leaky cable. It is impossible to directly drill holes in the wall to install the leaky cable. It is necessary to install a bracket on the wall to raise the leaky cable to meet the installation requirements of the leaky cable. Utility Model Content

One end of the fixing screw is threadedly connected with a fixing nut.

[0007] Preferably, both ends of the L-shaped bracket are fixedly connected with fixing plates, and the fixing plates are arranged on the side walls of the L-shaped bracket. The side walls of the fixing plates are provided with wall nuts, and the internal threads of the wall nuts are connected with screws, and the screws pass through the fixing plates and extend into the L-shaped bracket.

[0008] Preferably, the side wall of the L-shaped bracket is provided with an L-shaped plate, the bottom of the L-shaped plate is provided on the top of the L-shaped bracket, the bottom of the L-shaped plate is provided with an anti-slip nut, the internal thread of the anti-slip nut is connected with an anti-slip screw, and the anti-slip screw passes through the L-shaped plate and extends into the L-shaped bracket.
