Description

Technical Field

[0001] The utility model relates to the technical field of rail vehicle fire protection equipment, and more specifically, to a rail train auxiliary seat fire extinguishing device. Background Art

[0002] Rail train auxiliary seat fire extinguishing equipment refers to firefighting tools, such as fire extinguisher bottles, installed inside rail train cars to respond to fire emergencies. Conventional fire extinguisher installation methods use anchor bolts to connect the bottles to a base fixed inside the car. While this secures the bottles, it requires sequentially loosening the anchor bolts to separate them from the base for repairs, replacements, or emergency removal. This makes assembly and disassembly cumbersome and time-consuming, and prevents quick removal in emergencies.

[0003] After searching, the Chinese patent with the announcement number CN220917973U discloses a water-based fire extinguishing device for use on trains. The water-based fire extinguishing bottle of this utility model can be quickly fixed through the bottle body fixing assembly. At the same time, when the water-based fire extinguishing bottle needs to be disassembled, it only requires a simple operation of opening the pawl and rotating the driving arm, without repeatedly tightening the bolts. The water-based fire extinguishing bottle is easy and quick to disassemble and assemble.

[0004] When the above-mentioned fire extinguishing device is in use, the driving arm is rotated in the opposite direction until the fixing plate is reset. At this time, the water-based fire extinguisher bottle is fixed by the fixing plate in the circular clamp formed by the semicircular groove. However, the fire extinguisher bottle needs to be removed manually and then the discharge port is aimed at the fire source. There are certain safety hazards when extinguishing the fire, and it is easy to injure the user accidentally. Utility Model Content
