A Composite Fire Hydrant Interface

Abstract

The invention belongs to the technical field of fire-fighting appliances, specifically a composite fire hydrant interface, including a water outlet pipe, a water spray pipe, a plug-in fixing mechanism and an acceleration mechanism; the water spray pipe is fixedly connected to the left end of the water outlet pipe, and sprays water The right end of the pipe is provided with a plug-in fixing mechanism; the plug-in fixing mechanism includes a plug-in ring, a fixed ring, a mounting groove, a rotating block and a reset lever; the plug-in ring is fixedly connected to the outer surface of the fixed ring, and the plug-in ring The whole formed by connecting with the fixed ring is fixedly installed in the right end wall of the water spray pipe, and the right end of the splicing ring can be plugged into the left end wall of the water inlet and outlet pipe, and the outer surface of the right end of the splicing ring is uniformly provided with installation grooves; the installation The groove is connected with a rotating block through the elastic rotation of the spring; the present invention is mainly used to solve the problem that the fire hydrant carried by the fire truck in the prior art has a slow processing speed when dealing with high-altitude disasters, and it is difficult to rescue the trapped people at the first time. The connection strength of the fire hydrant interface is not high when the water pressure is high.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting appliances, in particular to a composite fire hydrant interface. Background technique [0002] Fire hydrant, officially called fire hydrant, is a fixed fire-fighting facility whose main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. There are indoor fire hydrants and outdoor fire hydrants. The fire protection system includes outdoor fire hydrant systems, indoor fire hydrant systems, fire extinguisher systems, and some automatic sprinkler systems, water cannon systems, gas fire extinguishing systems, fire detection systems, water mist systems, etc. The fire hydrant set is generally composed of fire box + fire hose + water gun + buckle + bolt + clip, etc. The fire hydrant is mainly used for fire trucks to take water from the municipal water supply network or outdoor fire water supply network to extinguish fires, and can also be dir...
