Miners' lamp

Abstract

The invention discloses a miner's lamp. The miner's lamp includes a lamp holder assembly, a power source assembly, and a wire electrically connecting the lamp holder assembly and the power source assembly; the lamp holder assembly includes a housing, a lighting lamp and a lighting switch assembly; a mounting hole is provided on the wall of the housing, and the The light switch assembly includes a micro switch arranged in the housing, an elastic sealing cover, and a positioning pin matched with the installation hole; the contact handle of the micro switch is located in the installation hole, and the sealing cover Covered on the contact handle of the micro switch, the positioning pin fixes the sealing cover in the installation hole. The invention has the advantages of good safety, convenient maintenance and long service life.

Description

technical field [0001] The invention belongs to lighting equipment, in particular to a miner's lamp. Background technique [0002] At present, the switch used to control the lighting bulbs in the miner's lamps used in domestic mines is mainly a rotary switch. The loose assembly of the rotary switch will cause the rotary switch to move axially, and the tight assembly will cause the rotary switch to be ineffective. Affect normal use. In addition, the structure of the rotary switch is a reed contact type, which is easy to generate electric sparks when turning on or off the miner's lamp. Because the structure of the rotary switch itself limits its sealing effect, it is easy to cause a gas explosion when gas leaks . [0003] Chinese patent document CN2842162Y discloses a miner's lamp lamp holder equipped with a safety switch, including a lamp ring, a lamp housing and a circuit board; There is a button hole connected to the base hole on the shell, and a button matching the end ...

AI Technical Summary

Problems solved by technology

Because this kind of miner's lamp adopts the way of bonding to realize the sealing fit between the button and the button hole, because the button is exposed to the air in the underground and is frequently touched and massaged, the button is easy to warp or even fall off, so the miner's lamp cannot be used in the underground

In addition, it is cumbersome to disassemble and repair the switch, and the button must be replaced again, and the button that is pasted again has a shorter service life because the bonding is not as stable as before

[0004] In addition, the traditional methane alarm device comprises a cover body with an air inlet and an air outlet, a methane sensor arranged in the cover and a filter screen bonded on the cover and positioned in the air inlet and the air outlet; The coal dust in the gas is easy to block the filter screen, so the filter screen needs to be replaced or cleaned after a period of time for the miner's lamp. Since the traditional methane alarm device uses bonding to fix the filter screen on the cover body, maintenance and replacement need to be replaced first. It is disassembled, and then a new filter screen is bonded; this kind of replacement and maintenance operation is complicated and time-consuming

[0005] In addition, the charging control circuit boards of existing rechargeable miner's lamps are all arranged in the lamp housing. Due to the small heat dissipation area of ​​the lamp cap, the lamp head will overheat during the charging process, which will seriously affect the use effect and use of the miner's lamp. life
