Abstract

The invention relates to an explosion-proof lamp. The explosion-proof lamp comprises a lamp shell, a transparent part, a transparent part sealing ring, a first fixed member and a second fixed member, wherein the lamp shell comprises a soleplate and a side wall which form a first storage cavity with one opening end, the side wall is provided with a fixed plate and a fixed rib which form a first storage groove together with the side wall and is also provided with a first installation part and a second installation part, one side of the transparent part sealing ring is provided with a first groove, the other side of the transparent part sealing ring is provided with a second groove and two projections with arc surfaces, the first fixed member comprises a first fixed column and a first fixed part, the second fixed member comprises a second fixed column and a second fixed part, the transparent part sealing ring is partially stored and protrudes the first storage groove, the first groove is buckled with the fixed rib, both the first fixed column and the second fixed column are respectively connected with the transparent part, and both the first fixed part and the second fixed part are respectively connected with the first installation part and the second installation part, so that the transparent part pushes against the arc surface and compresses the transparent part sealing ring so as to seal the first storage cavity. The explosion-proof lamp is good in sealing effect, and the transparent part is higher in reliability.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an explosion-proof lamp. Background technique [0002] The lamp housing and transparent parts of explosion-proof lamps are generally connected by threads. Explosion-proof lamps with this connection structure have the following two problems: (1) The transparent parts are subject to certain stress, and there is a risk of easy rupture; (2) After a long time of use, there will be tiny gaps in the connection part, resulting Its sealing effect becomes poor, and when it is used outdoors or in a humid environment, water seepage through gaps will not only affect the service life of explosion-proof lamps, but even affect its explosion-proof performance and bring safety hazards. Contents of the invention [0003] Based on this, it is necessary to provide an explosion-proof lamp with better sealing effect and higher reliability of transparent parts. [0004] An explosion-proof lamp, com...
