Straight stream water gun used for firefighting

Abstract

The invention discloses a straight stream water gun used for firefighting. The straight stream water gun comprises a water spraying barrel, a gun base and a handle. An external thread is arranged at one end of the water spraying barrel. One end of the gun base is internally provided with an internal thread matched with the external thread. The water spraying barrel is connected with the gun base through the threads. The water spraying barrel is internally provided with a water spraying channel to communicate with an inner cavity of the gun base. A water inlet is formed in the end, connected with the gun base, of the water spraying channel, and a water spraying outlet is formed in the other end, connected with the gun base, of the water spraying channel. The water inlet is located in one end of the gun base. The water spraying outlet is located in one end of the water spraying channel. The outer wall of the water spraying barrel is sleeved with a rotatable flow adjusting sleeve. A protruding switch knob is further arranged at the front end of the water spraying barrel. The handle comprises a fixed handle body and a movable handle body which are fixed to the upper portion and the lower portion of the gun base correspondingly. A dual-pressure nozzle is installed at the water spraying outlet. According to the straight stream water gun used for firefighting, the range of the water spraying gun can be increased, and the firefighting water gun is simple in structure, convenient to operate, capable of saving time and effort and high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a direct current water gun for fire-fighting. Background technique [0002] The fire water gun is a water jet tool for fire extinguishing. When it is connected with the hose, it will spray dense water flow. The fire water gun has the advantages of long range and large water volume. When extinguishing a fire, firefighters often use fire sprinklers to form a water network to control the spread of the fire. When the firefighters of fire departments in various places put out fires in buildings, they can only put out the fire first, and then use tools to break the doors and windows, etc. after the fire becomes smaller, so as to rescue people. In some places, the fire may be small. However, only one person is allowed to pass through, and the firefighters have no way to put out the fire and rescue people at the same time. They can only put out the fire with water guns f...

Problems solved by technology

When the firefighters of fire departments in various places put out fires in buildings, they can only put out the fire first, and then use tools to break the doors and windows, etc. after the fire becomes smaller, so as to rescue people. In some places, the fire may be small. However, only one person is allowed to pass through, and the firefighters have no way to extinguish the fire and rescue people at the same time. They can only extinguish the fire with water guns first, which delays the timing of rescue.

[0003] Due to the design of the nozzle, some existing fire water guns have a short range and cannot complete fire fighting work in various situations, and some fire water guns do not have a good control on the size of the water flow, which not only wastes the water source when fighting fires, but also The precious time for rescue is lost. In addition, during the fire fighting process, due to the relatively large fire intensity, firefighters need to implement a rescue plan for a long time. Most of the existing fire water guns use a fixed handle. Firefighters often have sore arms after fighting fires for a long time, and the existing technology has great hidden dangers
