Internal cubic non-blind-angle water gun

Abstract

The invention discloses an internal cubic non-blind-angle water gun and particularly discloses a fire-extinguishing water gun with a rotary nozzle, belonging to fire-fighting equipment. The internal cubic non-blind-angle water gun comprises a fire hose connector, a water gun switch, a water gun pipe, a water gun nozzle connecting nut and the nozzle, wherein the fire hose connector and the water gun switch are mutually connected, and the water gun pipe, the water gun nozzle connecting nut and the nozzle are in sequentially threaded connection. The internal cubic non-blind-angle water gun is characterized in that: a rotatable water gun connecting device is mounted between the water gun switch and the water gun pipe; and the nozzle is a bending nozzle. The water gun is of complete no-leakage under a high-pressure fire-extinguishing state; the water pipe can manually and limitlessly rotate at 360 DEG; and meanwhile, as a direct-flow water gun nozzle is changed into the bending water gun nozzle with the degree of curvature of 60-70 DEG and the water gun pipe is lengthened, the shortcoming that the water gun head of the common direct-flow cannot be extended into a room with a thick wall body and fire points in the room cannot be effectively shot through holding the water gun outdoors is overcome, and the fire-extinguishing efficiency is maximally increased and the safety of firemen is maximally protected. The internal cubic non-blind-angle water gun has the advantages of simple structure, easiness in manufacture and suitability for popularization and application in fire-fighting departments.

Description

technical field [0001] The invention belongs to fire-fighting equipment, in particular to a fire-extinguishing water gun with a rotating nozzle. Background technique [0002] Fire-fighting water guns are necessary supplies for fire fighters to extinguish fires on the spot. The commonly used fire-fighting water guns are DC water guns. The general DC water guns have a short tube and cannot penetrate the head of the water gun into the room for houses with thicker walls. The second is that the water gun nozzle is a straight water flow that can only change direction according to the angle of the water gun. When the firefighters cannot enter the room to extinguish the fire, the outdoor water gun cannot effectively shoot to the fire point in every dead corner of the room, and cannot exert the maximum effect of the water gun to extinguish the fire. Because of the above-mentioned reasons, the firefighters need to spray water in melee for eliminating the fire point in the indoor dead ...

AI Technical Summary

Problems solved by technology

[0002] The fire water gun is an essential item for fire fighters to extinguish fires on the spot. The commonly used fire water gun is a DC water gun. The general DC water gun has a short tube. For houses with thicker walls, the head of the water gun cannot be poked into the room.

The second is that the nozzle of the water gun is straight and the water flow can only change the direction according to the angle of the water gun. When the firefighters cannot enter the room to extinguish the fire, the water gun held outdoors cannot effectively shoot to the fire points in every dead corner of the room, and the maximum effect of the water gun cannot be exerted to extinguish the fire.

Due to the above reasons, firefighters need to spray water in close combat to eliminate the fire points in indoor dead corners. Once the top of the door collapses, it will cause fatal damage to the firefighters in close combat.

CN2835764 discloses a high-pressure water pipe rotary joint. This joint can not only meet the needs of changing the flow direction of low-viscosity fluid and connecting two parts at right angles when there is relative rotation or swing between the two parts, but also solves the problem of normal work in a high-pressure environment. , can meet the connection requirements when there is relative rotation between the connecting parts at right angles, so that when the fire extinguishing device needs to extinguish the fire, the preparation time is greatly reduced, and it can be moved arbitrarily with the size of the fire source area, gaining valuable time for fire extinguishing. But not suitable for handheld fire extinguisher
