Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire fighting water gun head which is easy to install. Background Art

[0002] Fire hoses are water-jet firefighting tools. When connected to a hose, they spray a dense, rich stream of water, offering long range and high water output. Depending on the form and characteristics of the jet, they can be categorized as direct current, spray, and multi-use. Depending on the fire situation, different nozzles are often required to enhance firefighting effectiveness and conserve water resources.

[0003] The patent document with the existing announcement number CN213491703U records a fire water gun that is easy to install. The device includes a gun head and a gun body, which are connected by a connecting piece. The gun head includes a nozzle head, a conical tube part and a convex ring part. Two slots are symmetrically provided on the side of the convex ring part. A limit strip is installed between the two slots. The limit strip includes an arc-shaped elastic piece and limit columns arranged at both ends of the arc-shaped elastic piece. The top of the two limit columns is provided with a pressing ball. When the gun head needs to be replaced, press the pressing ball, the arc-shaped elastic piece in the middle of the limit column is deformed, and the pressing ball retracts into the inner surface of the shell. The gun head can be removed for replacement by pushing and pulling the gun head outward.

[0004] However, this device still has certain defects in actual use. The device fixes the gun head by deforming the arc-shaped elastic piece in the middle of the limit column. Since the water pressure of fire hydrants is often large, the impact of high water pressure on the water gun head will be transmitted to the arc-shaped elastic piece, and in severe cases, the water gun head will be flushed out.

[0005] A fire hose head that is easy to install is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
