[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facilities. Their main function is to control combustibles, isolate combustible materials, and eliminate sources of ignition. Fire hydrant sets are generally composed of fire boxes, fire hoses, water guns, connectors, plugs, clips, etc. They are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. They can be directly connected to water hoses and water guns to discharge water for fire extinguishing. The fire hydrant system is also one of the important fire-fighting facilities for fighting fires.

[0022] The upper end of the vertical plate 13 is movably connected to a guide rod 7 , and the surface of the guide rod 7 is fixedly connected to the upper end of the anti-collision plate 6 .

[0023] Through the above technical solution and the provision of the guide rod 7, the purpose of guiding the upper end of the anti-collision plate 6 is achieved, thereby preventing the upper end of the anti-collision plate 6 from tilting.
