Explosion-proof signal lamp and sealing structure thereof

Abstract

The invention discloses an explosion-proof signal lamp and a sealing structure thereof. The explosion-proof signal lamp comprises a key cap (1), a battery box (2), a battery (3), an LED (light-emitting diode) flashlight plate assembly (4), an explosion-proof signal lamp circuit assembly (5) and the sealing structure. The sealing structure comprises a shell (6), a sealing ring and a locking screw (7). The shell (6) is inlaid on the battery box (2) and is sealed through the sealing ring. The locking screw (7) penetrates through the shell (6) and is tightly fixed with a screw hole in the battery box (2). The shell (6) and the battery box (2) jointly form a sealing space to seal the battery (3), the LED flashlight plate assembly (4) and the explosion-proof signal lamp circuit assembly (5). The explosion-proof signal lamp and the sealing structure thereof have the advantages that the full sealing of the signal lamp is better realized, and the defects of sealing failure for reasons that the sealing ring is collapsed under the effect of external force and the sealing ring is aged because the sealing ring is exposed in the air for a long time are eliminated.

Description

technical field [0001] The invention relates to the technical field of a signal lamp structure, in particular to an explosion-proof signal lamp and its sealing structure. Background technique [0002] For some equipment, how to timely and accurately understand the operating status of the equipment and deal with existing problems in a timely manner is a big problem for technicians. For this reason, engineering and technical personnel install signal lights on the equipment, and when the equipment breaks down or changes working status, it sends out a signal to remind the engineering and technical personnel to maintain it in time. [0003] Chinese patent application 200910190481.6 discloses a signal lamp, including a signal lamp body, the signal lamp body has a lamp cap, a light source is arranged inside the lamp cap, and a diffuser cover, the diffuser cover is detachably connected to the front end of the lamp cap, the astigmatism The cover has a tapered portion for scattering ...

AI Technical Summary

Problems solved by technology

[0006] However, the explosion-proof structure of the signal lamp in the prior art is very unreasonable, and the complete sealing of the signal lamp cannot be realized. During long-term use, it is easy to be deformed and exploded by external force, and it is easy to age when used in various harsh environments and cannot be explosion-proof.
