Fire-fighting lance capable of being fixed conveniently and rapidly and allowing spraying angle to be adjusted conveniently

Abstract

The invention relates to the technical field of fire-fighting lances, and discloses a fire-fighting lance capable of being fixed conveniently and rapidly and allowing the spraying angle to be adjustedconveniently. The fire-fighting lance capable of being fixed conveniently and rapidly and allowing the spraying angle to be adjusted conveniently comprises a base. A first inner cavity is formed in the base, and a connecting column is arranged in the first inner cavity in a penetrating mode. According to the fire-fighting lance capable of being fixed conveniently and rapidly and allowing the spraying angle to be adjusted conveniently, a lance body is clamped in a C-shaped elastic clamping ring, and then a bolt and a nut are screwed to stabilize the lance body; meanwhile, the upward or downward inclination angle of the lance body in a U-shaped frame can be adjusted through connecting rods and second bearings on the two sides of the C-shaped elastic clamping ring, and the lance body can berotated by 360 degrees through a rotary disc, a ball groove and movable balls; and the swing angle of the fire-fighting lance can be adjusted by only one fireman, consumption of the physical strengthof the fireman is effectively lowered, and the fire rescue progress is effectively accelerated.

Description

technical field [0001] The invention relates to the technical field of fire-fighting water guns, in particular to a fire-fighting water gun that is convenient and quick to fix and easy to adjust the spray angle. Background technique [0002] Fire water gun: It is a water jet tool for fire extinguishing. When it is connected with the water belt, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. According to the different jet forms and characteristics, it can be divided into: DC water gun, spray water gun, multi-water gun, etc. Among them, the commonly used water guns are direct current and spray water guns. [0003] For example, the Chinese patent No. is CN 104667464 A, a kind of fire-fighting water gun. The advantage of the fire-fighting water gun of this invention is that it has a booster, can increase the water pressure and its flow rate through the booster tube on the booster, and has an injection chamber. It can ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fire water gun that is convenient and quick to fix and easy to adjust the spray angle, which has the advantages of convenient, fast fixing and easy adjustment, and solves the problem that the positioning and rotation of the fire water gun is done by firefighters , In the fire scene, three or four firefighters are required to master the head of the fire water gun, and sometimes the firefighters need to keep swinging a certain angle. The reaction force of the powerful water gun is very large, and the powerful water gun needs to be continuously swung for a long time, which consumes a lot of physical strength, and consumes the manpower of firefighters to affect the progress of fire rescue.
