AI Technical Summary

Technical Problem

Traditional gas-fired extinguishers are cumbersome to assemble and disassemble, rely on tools, and are prone to leakage, making it difficult to meet the needs for rapid response and convenient maintenance, especially in the field or confined environments.

Method used

The cylinder adopts a cartridge-type gas cylinder design. After screwing in the connecting end cap, it automatically punctures the sealing film and opens the gas filling channel. Combined with the locking component and the vertical locking component, it can be quickly disassembled and sealed. The air pressure drives the locking engagement block to engage with the anti-rotation locking ring, ensuring the circumferential rotation freedom and vertical position locking of the gas cylinder.

Benefits of technology

It enables quick disassembly and assembly of gas cylinders without additional tools, improving the convenience of daily maintenance and emergency replacement, ensuring the safety and sealing reliability of the high-pressure gas release process, simplifying the maintenance process, and avoiding insufficient power problems caused by forgetting to replace them.

Abstract

The invention relates to the technical field of fire-fighting equipment, in particular to a quick disassembly and assembly type gas storage fire extinguisher which comprises a fire extinguisher main bottle body, a mounting cavity for containing a gas storage bottle is formed in the lower side of the fire extinguisher main bottle body, and a connecting end cover used for being connected with the gas storage bottle is connected into the mounting cavity through a vertical sliding mechanism. The fire extinguisher main bottle body is provided with a puncture type inflation needle used for puncturing a sealing film of the gas storage bottle and guiding gas, and the fire extinguisher main bottle body is further provided with a clamping assembly used for locking the circumferential rotation freedom degree of the gas storage bottle. According to the fire extinguisher, the plug-in mounting type gas storage bottle design is adopted, the main bottle body is pressed down after the connecting end cover is screwed in, then the sealing film can be automatically punctured, and air inflation can be conducted without tools, the bottom of the gas storage bottle is exposed to facilitate installation, the gas storage bottle is flush with the bottom face of the bottle body after retracting, and when an empty bottle is replaced, the gas storage bottle is reversely screwed off and a new bottle is installed, and then the fire extinguisher can be quickly recovered for standby application. And the convenience of maintenance and emergency replacement is obviously improved.
