Description

Rear handle of pulse air pressure spray gun Technical Field The utility model relates to the technical field of fire-fighting equipment, in particular to a rear grip of a pulse air pressure spray water gun. Background The fire extinguishing principle of the pulse air pressure spray gun is that compressed air is used as power, the compressed air is sprayed out by an ultra-fast opening exhaust valve in a very short time to push the fire extinguishing agent in the water storage cylinder and emit the fire extinguishing agent at a very high speed, atomized liquid particles are generated by friction collision of air and liquid molecules, the liquid particles have very large kinetic energy and can penetrate flame and ascending air flow and directly spray into a fire stove, the temperature of the flame is quickly reduced after the liquid particles are gasified, the fire extinguishing purpose is achieved, the pulse air pressure spray gun has the characteristics of quick operation and unfolding, water conservation, high efficiency, environmental protection, strong maneuverability and the like, various fire extinguishing additives can be used according to requirements during use, the use and maintenance are convenient, and the rear grip is an important component of the pulse air pressure spray gun. However, the stability of the existing rear grip is poor, and the grip is easily damaged due to the fact that the equipment generates larger impact force in the working process, so that the service life of the equipment is reduced. Disclosure of utility model The utility model aims to provide a rear handle of a pulse air pressure spray gun, which aims to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a handle behind pulse air pressure spraying squirt, includes the main valve body, the bottom surface joint of main valve body has the handle of holding, two locating holes have been seted up to the upper surface of holding the handle, first auxiliary hole has been seted up in the front of holding the handle, the second auxiliary hole has been seted up in the front of holding the handle, the connecting hole has been seted up to the inner wall of main valve body, the jackscrew has been seted up to the left surface of holding the handle. As a still further proposal of the utility model, the upper surface of the holding handle is provided with a water guide hole, and the inner wall of the water guide hole is fixedly connected with a first sealing ring. As a still further scheme of the utility model, the inner walls of the two positioning holes are fixedly connected with second sealing rings, and the first sealing rings and the two second sealing rings are made of rubber materials. As still further scheme of the utility model, the upper surface of the holding handle is provided with a mounting hole, and the inner wall of the mounting hole is connected with a positioning pin in a threaded manner. As a still further proposal of the utility model, the upper surface of the holding handle is fixedly connected with a protection pad, and the outer surface of the holding handle is sprayed with an anti-corrosion paint surface. Compared with the prior art, the utility model has the beneficial effects that: This handle behind pulse atmospheric pressure spraying squirt through holding handle, locating hole, first auxiliary hole, second auxiliary hole, connecting hole, jackscrew and the setting of water guide hole, can make people carry out two-way fixed to the main valve body, makes the main valve body more stable in the in-process of work to make the life of equipment longer, the setting of first sealing washer, second sealing washer and protection pad not only can make the sealed effect of equipment better, can protect the main valve body moreover.
