Anti-falling fire extinguishing fastening bolt

Abstract

The invention relates to the technical field of fire extinguishing, and discloses an anti-falling fire extinguishing fastening bolt which comprises an upper fastening disc and a lower fastening disc, the inner wall of the upper fastening disc is fixedly connected with a first fixing rod, the right side of the first fixing rod is fixedly connected with a sliding rail, and the front face of the sliding rail is movably connected with a pressed plate; a dielectric plate is fixedly connected to the bottom of the pressed plate, a second fixing rod is fixedly connected to the position, close to the bottom of the first fixing rod, of the inner wall of the upper fastening disc, a clamping box is fixedly connected to the right side of the second fixing rod, and a positive plate is fixedly connected into the clamping box. According to the anti-falling fire extinguishing fastening bolt, a pressed plate moves downwards left and right under the pressure of water, so that a dielectric plate is driven to move downwards, then the dielectric plate moves between a positive plate and a negative plate to enable the negative plate to be powered on, and finally, a buzzer is electrically connected with a piezoresistor; therefore, the effect of automatically alarming after the water pressure in the fire-fighting lance is too high is achieved.

Description

technical field [0001] The invention relates to the field of fire-fighting and fire-extinguishing technology, in particular to an anti-falling-off fire-fighting and fire-extinguishing fastening bolt. Background technique [0002] The fire water gun is a water jet tool for fire extinguishing. When it is connected with the hose, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. Firefighters usually use water pressure to control the range and water volume. Some fire water nozzles are often loosely connected at the connection of the water nozzle, causing the connection of the water nozzle to fall off, which seriously affects the working efficiency of the fire nozzle. [0003] The long-term use of the fire water gun will cause the connection at the interface to loosen. When the firefighters use the fire water gun to extinguish the fire, the high pressure inside the water gun may cause the connection to fall off. Under high...
