[0002] A fire hose is a hose used to transport high - pressure water or flame - retardant liquids such as foam. Traditional fire hoses have a rubber lining and are wrapped with linen fabric on the outer surface. Advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose have metal connectors, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spraying pressure. After retrieval, in the prior art (publication number: CN202220970786.X), an internal - buckle anti - detachment hose connector and a water distribution manifold are disclosed. It is recorded in the text that "a lock catch is arranged on the connector body, the first end of the lock catch extends into the clamping groove, and the second end is located outside the connector body. When a force is applied to the second end, the first end can be detached from the clamping groove. When the first end is inside the clamping groove, the male connector extending into the clamping groove can be locked. When an external force is used to drive the movement of the second end to drive the first end to move out of the clamping groove, the male connector is in an unlocked state and can be removed by screwing. In this way, the problem of the pipe body rotating in the reverse direction and falling off can be avoided", but in the prior art, the sealing at the place where the lock catch extends into the clamping groove of the fire hose connector is not good, and water seepage is very likely to occur, resulting in insufficient water pressure.
