Production process for preparing high protection grade miners' lamp

Abstract

The invention discloses a production process for preparing miners lamp with protection level, and relates to the lamp illumination technology field and the miner safety production technology field. An edge extending out is arranged on the side of an elastic switch press key, the inlaid ring of the switch press key is made of engineering plastics which is homogeneous with the casing body of the switch, when the casing body and the inlaid ring of the switch press key are integrated through hot melting by adopting the ultrasonic wave hot melting process, the switch press key is inlaid on the casing body, the edge extending out on the side of an elastic switch press key is pressed in a groove shaped space between the inlaid ring of the switch press key and the casing body, a lamp cover and a lamp surface glass which are made of compatible engineering plastics are integrated through hot melting by adopting the ultrasonic wave hot melting process, and thereby the entire casing is in the fully sealed structural form. The process of the invention enables the complete lamp to achieve the fully sealed waterproofing structure in the true sense, and enables the protection level of the miners lamp become diving type from waterproofing type. The promotion and the application of the production process can enable the protection level of the miners lamp to be upgraded to be intrinsic safety type from coal mine safety authorization type.

Description

technical field [0001] The process of the invention relates to the technical field of lighting fixtures and the technical field of mine safety production, and is specifically a production process for preparing an integral fully sealed high-protection grade miner's lamp. Background technique [0002] The protection level of the miner's lamp essentially refers to the degree of sealing between the inside and the outside of the miner's lamp. [0003] The new national standard GB7957-2003 "General Requirements for Safety Performance of Miner's Lamps" stipulates that the protection level of miner's lamps in my country is IP54 waterproof type, but the protection level of miner's lamps in the international market has been developing to IP67 diving type; the safety level of miner's lamps in my country is coal mine safety licensed type, The safety level of the international miner's lamp has been required to reach the intrinsically safe type. The protection level is the basis of the sa...

AI Technical Summary

Problems solved by technology

However, there are still some separate parts on the above-mentioned integrated industrial and mining lamps, such as switch buttons, charging jacks, lamp surface glass, etc., and they cannot be completely sealed and connected with the housing as a whole.

In the prior art, such components in similar products are also separated from the main body. The method that the applicant once adopted is to glue them together with silica gel or seal them with a sealing ring. These methods cannot achieve complete sealing. purpose, and there is a hidden danger of detachment of the bonded parts, therefore, the protection level of the miner's lamp cannot be improved for a long time
