Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the present invention includes a lamp housing 1, a lampshade 2 and a protective net 3. The housing chamber for lighting components is enclosed between the lamp housing 1 and the lamp housing 2. The end surface of the lamp housing 1 close to the lamp housing 2 is provided with a chute 4 and a first annular protrusion. Platform 5, the cross section of the first annular boss 5 is a triangular or trapezoidal structure, the outer side of the first annular boss 5 is a first inclined surface 6, and a sealing ring 7 is arranged on the first inclined surface 6, and the sealing ring 7 is indented Structural design, the outer side of the sealing ring 7 protrudes from the first inclined surface 6, the preferred trapezoidal structure in this embodiment, the notch width of the chute 4 is smaller than the width of the bottom of the ch...

Abstract

The invention discloses a dustproof lamp for a mine. The dustproof for the mine comprises a lamp housing and a lampshade, wherein an accommodating cavity for an illumination assembly is defined and assembled between the lamp housing and the lampshade in a surrounding way; slide grooves and a first annular lug boss are arranged at the end surface, near the lampshade, of the lamp housing; the notchwidth of the slide groove is smaller than the width of the groove bottom; a plurality of slide grooves are uniformly formed; the groove depths of the slide grooves are sequentially increased on the extension lines of the slide grooves; the extension line of each slide groove is in an arc shape; the first annular lug boss is provided with a first inclined surface; a sealing ring is arranged on thefirst inclined surface; the edge of the lampshade is provided with a second inclined surface and a plurality of slide blocks matched with the slide grooves; the slide blocks and the slide grooves areglidingly matched; and the second inclined surface and the first inclined surface are matched. Through the sliding clamping of the slide blocks and the slide grooves, the self-adaptation tight matching between the lampshade and the lamp housing can be realized; and through the processive sealed matching between the first annular lug boss and the second annular lug boss, the advantages of fast andconvenient installation and high sealing performance are realized.

Description

technical field [0001] The invention belongs to the technical field of mine equipment, and in particular relates to a mine dustproof lamp. Background technique [0002] Mining is the technology and science of extracting mineral resources from within the Earth's crust and from the surface. Mining in a broad sense also includes the extraction of coal and oil. The mining industry is an important raw material industry, metal ore is the main raw material for the smelting industry, and non-metallic ore is an important chemical raw material and building material. [0003] In the basic principles of underground mining of metal deposits, the well field must be divided into stages (or panels) first, and then the stages (or panels) are divided into ore blocks (or mining areas). Mining includes three tasks: mining, cutting, and mining. The mining is arranged according to the size of the constituent elements of the ore block, and solves the problems of pedestrians, ore transportation, ...
