fig. 2 is a schematic diagram of the explosion structure of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the present embodiment provides an explosion-proof lighting power supply, which includes a housing 1, a square flange 2, a cover plate 3, an observation window 5, a power supply body 8, and a plurality of stud structures 6. The power supply body 8 is arranged in the shell 1, and the shell 1 is made of an aluminum alloy material. The front side of the shell 1 is provided with a plurality of outlet hole sleeves 4, and external cables penetrate through the outlet hole sleeves 4 to be connected with the power supply body 8. Square flange 2 locates 1 top of casing, and square flange 2 can set up to integrated into one piece with casing 1, apron 3 is located on square flange 2, apron 3 is connected with square flange 2 through double-screw bolt structure 6, observation window 5 is located on apron 3. The condition of the internal power supply body 8 can be observed at any time by setting the observation window 5, so that the production safety is ensured.

As shown in fig. 2, the observation window 5 includes a lens barrel 51, a rubber pad 52, a lens 53, a pressing ring 54, and a threaded ring 55, the lens barrel 51 is fixed at the center of the cover plate 3, the rubber pad 52 is disposed in the lens barrel 51, the lens 53 is located below the rubber pad 52, the pressing ring 54 is located below the lens 53, and the threaded ring 55 is located below the pressing ring 54; the thread ring 55 is provided with an external thread, the lens barrel 51 is provided with an internal thread matched with the external thread, and the thread ring 55 is positioned in the lens barrel 51.
