Description

Technical Field

[0001] The utility model relates to compressed oxygen self-rescuer equipment, in particular to a highly adaptable 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 airbags and purification tanks, 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.

[0035] A lower shell 1, wherein the upper end of the lower shell 1 is provided with a corresponding opening, and the side wall thereof is a sandwich structure and a corresponding hollow cavity 2 is provided at the sandwich position, and the hollow cavity 2 is externally connected to a deflation valve 3 fixedly mounted on the side wall of the lower shell 1;

[0036] An upper shell 4, which is disposed on the upper end of the lower shell 1, is used to close the opening of the lower shell 1 and form a receiving chamber for placing the compressed oxygen self-rescuer with the lower shell 1;

[0037] An adsorption locking mechanism, the adsorption locking mechanism includes a connecting piece 5 with an annular structure fixed to the lower end surface of the upper shell 4, and a rubber piece 6 fixed to the other end portion of the connecting piece 5 not connected to the upper shell 4, the upper end of the lower shell 1 is provided with an embedding hole 7 connected to the hollow cavity 2 at a position corresponding to the rubber piece 6, and a corresponding annular piece 8 is fixed in the embedding hole 7; the upper shell 4 is covered above the lower shell 1, and the connecting piece 5 is inserted into the embedding hole 7 until the rubber piece 6 abuts against the upper end surface of the annular piece 8, and the external equipment draws negative pressure to the hollow cavity 2, and the rubber piece 6 is adsorbed on the annular piece 8 and closes the middle circular hole of the annular piece 8.

[0038] On the basis of ensuring the stability of the locking connection between the upper and lower shells, the utility model provides an adsorption locking mechanism composed of a connecting piece 5 and a rubber piece 6 to cooperate with the lower shell 1 of the hollow structure for locking and connecting the upper shell 4; the upper end of the hollow lower shell 1 is provided with an embedding hole 7 connected to the hollow cavity 2 at a position corresponding to the rubber piece 6, and a corresponding annular piece 8 is fixedly connected in the embedding hole 7. The upper shell 4 is covered above the lower shell 1 and the connecting piece 5 is inserted into the embedding hole 7. The rubber piece 6 abuts against the upper end surface of the annular piece 8. A commercially available vacuum pump is used to draw negative pressure into the hollow cavity 2 so that the rubber piece 6 is adsorbed above the annular piece 8 and closes the central circular hole of the annular piece 8. By pumping negative pressure into the hollow cavity 2, the rubber component 6 is adsorbed and blocked in the middle circular hole of the annular component 8, and then the upper and lower shells are firmly locked and connected by the tightly adsorbed rubber component 6.

The setting of the stoppers 9 can not only improve the connection stability between the upper shell 4 and the lower shell 1, but also make the stoppers 9 connected with the lower shell 1 to limit the position through the height setting when the upper and lower shells are connected, so as to facilitate the rapid insertion of the rubber member 6 of the adsorption locking mechanism into the embedding hole 7, thereby improving the convenience and practical effect of the connection between the upper and lower shells.

The outer surface of the closing piece 10 is provided with a plurality of raised horizontal stripes, which can effectively protect the deflation valve 3 and prevent gas from leaking out.

[0045] A group of reinforcement strips 11 for strengthening the stability of the shells are arranged on the front and rear sides of the upper shell 4 and the lower shell 1. The two ends of the reinforcement strip 11 on the upper shell 4 extend to the upper and lower ends of the upper shell 4 respectively, and the two ends of the reinforcement strip 11 on the lower shell 1 extend to the upper and lower ends of the lower shell 1 respectively.
