fire extinguisher launcher

Abstract

The invention discloses a fire extinguishing bomb launcher. The fire extinguishing bomb launcher comprises a barrel, an arming mechanism, a sighting telescope and a launching sleeve; the barrel is made of an aluminum alloy; the arming mechanism comprises a shell, a button connected with the shell in a sliding manner, and a pin shaft for controlling the button to slide or still relatively to the shell; a power source and a circuit board which are electrically connected with each other are arranged in the shell; a first contact terminal and a second contact terminal are arranged on the button; a return spring is arranged between the button and the shell; a first contact and a second contact are arranged on the circuit board; a sliding groove is formed in the pin shaft; the sighting telescope comprises a substrate, a slider and an optical sight; the launching sleeve comprises a sleeve body; two contact terminals are detachably arranged in the sleeve body and electrically connected with the circuit board. The fire extinguishing bomb launcher of such a structure has the advantages of convenient assembling and disassembling, high launching accuracy, high sighting efficiency, high arming reliability and low wrong arming rate.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a fire extinguishing bomb launcher. Background technique [0002] Fire extinguishing plays an important role in the world economy. The direct and indirect economic losses caused by forest fires, grassland fires, oil tank fires and high-rise fires to our country and human society every year are inestimable. [0003] In the prior art, in order to better protect the personal safety of firefighters, a fire extinguishing bomb launcher is used to extinguish the fire, the fire extinguishing material is filled into the warhead, and the fire extinguishing material is launched to the fire scene in the form of a mortar or a rocket launcher. In the process, the personal safety of firefighters is fully protected. The current fire extinguishing bomb launcher includes a barrel and a launch sleeve arranged at the rear end of the barrel. The launch sleeve includes a sleeve b...

AI Technical Summary

Problems solved by technology

The fire extinguishing bomb launcher in the prior art has the following defects: 1) It is inconvenient to assemble and disassemble, especially for the anchorage of vulnerable parts, the assembly and disassembly process is complicated; 2) During the firing process, the firing button slides relative to the casing, making the firing trigger The head is in contact with the firing contact to conduct the firing circuit, but usually only one firing circuit is constructed. When used for a long time, the firing contact is worn or other reasons are prone to poor contact between the firing contact and the firing contact. It makes the firing malfunction and reduces the reliability of the firing process; 3) It is easy to cause false shooting; 4) For different firing personnel, the aiming process is inconvenient and the aiming efficiency is low; 5) The barrel is easy to shake during the firing process, resulting in firing accuracy lower
