Matching external thread, the inner wall of the fire pipe is fixedly installed with a limit baffle, a limit slider and an annular spacer in turn from top to bottom, the inner wall of the fire pipe is movably installed with a spacer, and the locking handle The bottom of the wheel is fixedly installed with a spring through the bearing, the bottom of the spring is fixedly connected to the pressure block, the top of the spacer block is provided with a groove matching the pressure block, and the side wall of the spacer block is provided with a limit slide. block matching limit chute, and a water outlet hole is opened on the isolation block. The beneficial effect of the invention is that it has the characteristics of simple structure, convenient use and easy opening.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire hydrant which is easy to open. Background technique [0002] Fire hydrants are the main equipment for fire extinguishing in today's society. They are connected to underground water pipes and are installed everywhere beside roads. The existing fire hydrant valve body and valve stem are basically directly connected to the water pipe above the road surface, and in cold winter or snowy weather, the outdoor fire hydrants will basically be frozen by water and cause fire hazards. The bolt cannot be opened. Once a fire occurs at this time, there is no way to extinguish the fire in time. Therefore, be necessary to design a kind of fire hydrant that also can not be frozen because of freezing when cold winter or temperature is lower. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the defects of the prior art and pro...
