Fire-fighting waterflow direction changing all-round gun

Abstract

The invention discloses a fire-fighting waterflow direction changing all-round gun, and relates to the fire-fighting technical field. The gun comprises a gun head, a gun tube, a waterflow ball-shaped valve, and a water gun connector, wherein the gun head, the gun tube, the waterflow-ball-shaped valve and the water gun connector are connected in sequence, the gun tube is divided into an upper gun tube and a lower gun tube which are connected in a movable mode, and the upper gun tube is fixed in a rotating mode in a range of 0 degree to 90 degrees relative to the lower gun tube. Moreover, the rotating connection way is that the lower end face of the upper gun tube and the upper end face of the lower gun tube are respectively provided with an extended ring, and the two extended rings are buckled and hoped through a buckle ring. Sealing rings are arranged between the two extended rings, and arranged in corresponding grooves of an upper extended ring or / and a lower extended ring. The fire-fighting waterflow direction changing all-round gun has the advantages of integrating all advantages of a traditional straight stream water gun and better achieving difficult fire-fighting tasks which can not be finished by an existing water gun due to angles. Compared with the prior art, the fire-fighting waterflow direction changing all-round gun changes little in shape and weight relative to the existing water gun, is more flexible, lighter, safer and wider in functions, can effectively save fire-fighting time, and lower loss due to fires to minimum.

Description

technical field [0001] The invention relates to the technical field of fire fighting, and further relates to a direction-changing fire gun. Background technique [0002] In the prior art, there are certain defects in the fire gun: the hose is difficult or impossible to bend due to the high pressure when the water gun is discharged, and after bending (the hose is bent), because the front part of the bend is too long, it is not easy to control ( After the hose bends and becomes soft and swings back and forth), it cannot achieve the purpose and expectation of fire extinguishing, and has to get closer to the source of danger or expose the body to danger, which also greatly increases the physical exertion and labor intensity of firefighters ( Resist the force of the extra direction) and reduce the occupational safety factor of firefighters (the body is exposed to the source of danger). [0003] Therefore, it is necessary to solve the problem of fire gun changing direction. Con...
