Description
Technical field
The invention belongs to fire fighting device technical field, specifically a kind of fire hydrant.
Background technique
Fire hydrant, formal call are fire hydrant, and a kind of fixed fire fighting device, main function is control combustible, isolation
Oxidizer eliminates ignition source.Divide indoor fire hydrant and outdoor fire hydrant.Fire hydrant mainly for fire fighting truck from municipal water supply pipe network or
Fire extinguishing is implemented in the water intaking of outdoor fire fighting water supply network, can also be directly connected to water band, hydraulic giant goes out above-water method.The fire so indoor and outdoor disappears
Tying system is also one of the important fire fighting device to fight a fire.Fire hydrant should be placed in the public shared sky such as corridor or hall
Between in, generally which kind of decoration can cannot be made to it, it is desirable that there is eye-catching mark (to write that " disappear fire exactly in the wall in above-mentioned space
Bolt "), and the object that must not place obstacles in front of it, avoid the unlatching for influencing Door for fire hydrant；Fire hydrant is not generally located at room (such as
Box) in, the regulation of fire-fighting is not met, the timely rescue of fire fighter is also unfavorable for.
Most of fire hydrants used are needed when plugging into fire hose by the water band of fire hose at present in the prior art
Interface screws in fire hydrant, then opens the valve of fire hydrant again, carries out out above-water method.When the process needs to spend certain
Between, it is unfavorable for that fire-extinguishing operations are unfolded at the first time, and have certain consumption to the physical strength of operator, the fire-fighting work under docking produces
It is raw to influence.
Summary of the invention
In order to make up for the deficiencies of the prior art, a kind of fire hydrant proposed by the present invention.It is existing present invention is mainly used for solving
The hose coupling of fire hose screws in time-consuming and laborious in fire hydrant in technology, is unfavorable for that fire-fighting work is unfolded at the first time.
The technical solution adopted by the present invention to solve the technical problems is: a kind of fire hydrant of the present invention, comprising: bolt
Body, valve, thread spindle, piston and water outlet, water outlet connect hose coupling；Between the piston upper surface and water outlet top
Be fixed with folded sheet, and folded sheet is made of soft material, folded sheet designed for prevent water reflux return body, guarantee water from
Water outlet flows into hose coupling；Equally distributed notch is provided on the screw thread of the thread spindle；It is offered at the thread spindle
No.1 sliding slot；Gear is provided in the No.1 sliding slot, and gear is fixed on No.1 chute wall by shaft；The gear
