Technical Field

[0001] The utility model relates to the technical field of fire-fighting water guns, in particular to a fire-fighting water gun capable of preventing a water pipe from falling off. Background Art

[0002] A fire hose is a device used to extinguish fires. It uses high-pressure water to extinguish fires. A fire hose is usually composed of a nozzle, a water supply system, and a control device. It can spray water at high speed onto the fire scene, effectively reducing the fire and cooling the burning object, thereby controlling and extinguishing the fire. During the use of the fire hose, if the fixing screws at the water pipe connection are not tightened or loose, and the fire hose has been used for a long time, the water pipe may age, deteriorate, crack, etc., which will cause the water pipe connected to the fire hose to fall off. The falling water pipe will cause the safety of firefighters and affect the progress of firefighting work. Therefore, the present invention proposes a fire hose that prevents the water pipe from falling off to solve the problems mentioned in the above background technology. Utility Model Content
