A fire water gun quickly assembled by using multi-stage clamping positions

Abstract

The invention discloses a firefighting lance capable of being quickly assembled through multi-step clamping. The firefighting lance structurally comprises a lance body, a nozzle, a valve, a control valve handle, a connecting ring and a quick assembly clamping structure. The lance and a water conveying belt are firmly installed and connected in a multi-step clamping mode through the arranged quickassembly clamping structure, so that normal and quick firefighting work is guaranteed; clamping balls are quickly and accurately aligned with clamping inlets by utilizing heteropolar-magnet attractionforce of arranged magnet inserts, the clamping speed is increased, and thus the installing speed of the lance is increased and firefighting timeliness is effectively achieved; the lance and the waterconveying belt are installed well in a semi-pushing semi-rotating mode by utilizing arranged inserting rail grooves and rotating rail grooves, and the defects that multiple circles of rotating are required in a threaded connection mode of the prior art, and time and labor are wasted are overcome; clamping grooves are formed so that the clamping balls can be firmly clamped in the clamping groovesby utilizing ultrahigh water pressure during water spraying, and thus installation firmness is improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, more precisely, it relates to a fire-fighting water gun that utilizes multi-stage clamping positions for rapid assembly. Background technique [0002] The fire water gun is a water jet tool for fire extinguishing. When it is connected with the water belt, it will spray dense and substantial water flow, which has the advantages of long range and large water volume. But there are following defects in the fire-fighting nozzle of prior art: [0003] 1. The traditional fire water gun is connected with the joint of the water belt by thread engagement, but as the number of times of use increases, the thread will be gradually smoothed after repeated rotation and engagement. If the water pressure is too high, it may cause the water gun to separate from the water belt, which will affect the fire fighting work; [0004] 2. Due to the large mass of the water gun, the threaded rotary connect...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a fire-fighting water gun that utilizes multi-stage clamping positions to quickly assemble, so as to solve the problem that the fire-fighting water gun in the prior art is connected to the joint of the water delivery belt in a threaded manner. As the number of times of use increases, the thread will be gradually smoothed after repeated rotation and engagement. During the fire-fighting work, due to the excessive water pressure on the water gun, the water gun may be separated from the water delivery belt, which will affect the fire-fighting work. The quality of the water gun is relatively large, and it adopts the threaded rotary connection method. It needs to be rotated multiple times with the water gun to connect, which is laborious and time-consuming, and does not meet the timeliness required by firefighting work.
