An adjustable fire water nozzle

Abstract

The invention belongs to the technical field of fire-fighting tools and discloses an adjustable fire-fighting water gun. The invention comprises a water inlet valve, a fire water gun body, a buffer regulating pipe and a water direction adjusting nozzle connected in sequence, a throttling sphere is rotationally connected in the water inlet valve, and an L-shaped channel is arranged in the throttling sphere; the throttling sphere is connected with an adjusting The adjustment piece is rotatably connected to the water inlet valve; there are multiple positioning piece mechanisms in the water inlet valve, each positioning mechanism includes a T-shaped adjustment hole, a compression spring and a T-shaped positioning piece, and the T-shaped positioning piece is slidingly connected In the T-shaped adjusting hole, the compression spring is arranged between the T-shaped positioning piece and the inner end surface of the T-shaped adjusting hole; the side opposite to the water inlet of the throttling sphere is provided with a plurality of arc-shaped positioning grooves, and each T-shaped positioning piece One end of each is snapped into the corresponding arc-shaped positioning groove. The invention can achieve the effect of adjusting the flow rate, ensure the stability of the throttling sphere, have a certain protective effect on the human body, have better spraying effect, and can reduce the waste of water.

Description

An adjustable fire water gun technical field [0001] The invention belongs to the technical field of fire-fighting tools, and in particular relates to an adjustable fire-fighting water gun. Background technique [0002] The fire-fighting water gun is a water-jetting tool for fire-fighting, and when it is connected with a water hose, it will spray a dense and substantial flow of water. has range According to the different jet forms and characteristics, it can be divided into: direct current water gun, spray water gun, multi-use water gun, etc. The water guns commonly used in China are DC and spray water guns; but traditional fire water guns do not have the ability to adjust flow and direction. It can make the existing fire-fighting water gun appear to have a single function and cannot meet the needs of fire-fighting. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems existing in the prior art, the object of the present invention is to provide a ki...
