Wireless charging miner lamp with good sealing performance and sealing method thereof

Abstract

The invention discloses a wireless charging miner lamp with good sealing performance, and specifically relates to the field of mine electrical appliances. The miner lamp comprises a shell of which thebottom is open, and the device further comprises a sealing device, wherein the sealing device comprises a U-shaped bottom shell matched with the open type outer shell; the U-shaped bottom shell is arranged at the bottom of the outer shell; a bolt used for fastening is arranged at the bottom of the U-shaped bottom shell in a penetrating mode and extends into the outer shell; a fixing block locatedin the outer shell is arranged on the bolt in a penetrating mode; a transverse plate is fixedly arranged at the top of the fixing block, the bolt penetrates through the transverse plate, and a notchclamped with the transverse plate is formed in the inner wall of the outer shell. Through screwing the bolt, the bolt penetrates the transverse plate and the fixing block so that the transverse plateand the fixing block move together, the transverse plate is clamped in the notch, the outer shell is driven to move downwards, the U-shaped bottom shell is driven to move upwards until the U-shaped bottom shell is tightly attached to the outer shell, a joint can be well sealed through a sealing ring made of rubber materials, the sealing performance of the joint is guaranteed, and the miner lamp iseasy and convenient to use and good in sealing performance.

Description

technical field [0001] The invention relates to the field of mining electrical appliances, in particular to a wireless charging miner's lamp with good sealing performance and a sealing method thereof. Background technique [0002] Miner's lamp is the abbreviation of mining lamps or industrial and mining lamps, and the general name of special lighting lamps used in mines. The miner's lamps developed and sold by Tongming Electric are suitable for underground coal mines where there is a risk of gas (methane) coal dust explosion; the roadways in the mining area at the bottom of the mine can also be used in infrastructure mine roadways and chambers with large water spray. Main application: It is used for safety lighting and emergency rescue lighting in environments with flammable, explosive and combustible gases such as mines, petroleum, chemicals, railways, transportation, and storage.
