Problems solved by technology

However, the gasket cannot be sealed to meet the IP66 waterproof requirements. The common method is to achieve waterproofing by dripping glue, but the glue is easy to penetrate into the gasket, which will affect the explosion-proof performance of the lamp.

Embodiment Construction

[0012] The specific implementation of the present invention will be described mainly below in conjunction with the accompanying drawings.

[0013] The following will take the miner's lamp as an example to describe the structural characteristics of the present invention in detail.

[0014] see figure 1 and figure 2 , The miner's lamp 100 of this embodiment includes a first housing 110 , a second housing 120 , and a transparent member 130 . The first casing 110 is fixedly connected to the second casing 120, and the transparent member 130 is embedded in the light-transmitting window opened by the second casing 120. The above three together form a triangular prism-shaped storage cavity, that is, a flameproof Cavity 111. The light source (not shown) is accommodated in the explosion-proof chamber 111 .

[0015] The explosion-proof sealing structure of this embodiment is located between the explosion-proof cavity 111 and the outside world, and includes a metal gasket 140 held be...

Abstract

An explosion-proof seal structure is located between an explosion-proof cavity and the outside and comprises a metal gasket abutted against between explosion-proof surfaces formed by two objects, sealant filled between the explosion-proof surfaces and an elastic sealing element clamped between the two objects. The sealant is located on one side of the metal gasket close to the explosion-proof cavity, the elastic sealing element and the metal gasket are arranged side by side, and the elastic sealing element is located between the sealant and the metal gasket. The elastic sealing element is added between the metal gasket and the sealant to prevent the sealant from flowing into the metal gasket in coating and then affecting the explosion-proof performance of the explosion-proof seal structure, and the explosion-proof seal structure has the advantages of being simple in structure, safe and reliable.

Description

【Technical field】 [0001] The invention relates to a flameproof sealing structure. 【Background technique】 [0002] Mining explosion-proof lamps have stricter requirements on explosion-proof, and it is required that there should be no sundries in the explosion-proof surface so as not to affect the explosion-proof performance. For mining explosion-proof lamps, a metal liner is usually required at the joint between the transparent part and the shell. The metal liner has the functions of flame retardancy and arc extinguishing. However, the gasket cannot be sealed to meet the IP66 waterproof requirements. The common method is to achieve waterproofing by dripping glue, but the glue is easy to penetrate into the gasket, which will affect the explosion-proof performance of the lamp. 【Content of invention】 [0003] In view of the above situation, it is necessary to provide a flameproof sealing structure with better flameproof performance. [0004] An explosion-proof sealing struct...
