Description

Technical Field

[0001] The utility model relates to compressed oxygen self-rescuer equipment, in particular to a quickly disassembled compressed oxygen self-rescuer shell and a self-rescuer. Background Art

[0002] A self-rescuer is a portable respiratory protection device used by personnel underground to prevent poisoning by harmful gases or suffocation due to lack of oxygen when a fire, gas or coal dust explosion, or coal and gas explosion occurs in a mine or tunnel. A self-rescuer is a small, light, and easy-to-carry device for protecting personal respiratory organs. Due to the characteristics of the self-rescuer, a corresponding shell needs to be used for storage and protection. The traditional self-rescuer shell is composed of two upper and lower shells. The components of the self-rescuer, such as the airbag and the purification tank, are placed in the lower shell, and the upper shell is covered. The two sides between the upper and lower shells are locked by matching buckles. In order to avoid scratches and other situations during carrying, which may cause the buckle to fall off and the self-rescuer components to be scattered and damaged, the prior art will extend the buckle connecting the lower shell upward to the top of the upper shell and then overlap the two, and protect the overlap with Velcro or a groove provided on the upper shell to cooperate with the cover body.

[0003] Furthermore, the traditional shell uses a buckle structure to lock the upper and lower shells, which is a rather chaotic situation when used. The buckle is easy to be discarded or difficult to find after being disassembled, which makes it necessary to purchase the corresponding locking mechanism to reuse the self-rescuer, and the practical performance is poor.

[0004] The shell of the self-rescuer is not only used for storage and protection, but also needs to be easy and fast to disassemble and assemble in order to save time for the trapped people and save their lives. However, the shell of the compressed oxygen self-rescuer or the shell of the compressed oxygen self-rescuer is slow to disassemble and the disassembly process is complicated and cumbersome.

[0005] Therefore, on the basis of ensuring the stability of the connection between the upper and lower shells, designing a compressed oxygen self-rescuer shell and self-rescuer that can be easily and quickly disassembled and assembled is the research purpose of the present utility model.
