Abstract
Description
Technical Field

[0002] As an indispensable daily necessity, lamps have entered all aspects of our lives, and lamps are used in various fields. Based on the different use areas, the design directions are also different. As lamps in complex environments, most of them have adaptive protection designs. The protection is not completely internal. In some cases, the external environment must also be protected. This is the design concept of explosion-proof lamps. For example, explosion-proof lamps that can be directly retrieved are generally used in dangerous places where flammable gases and flammable dust exist. They can prevent the arcs, sparks and high temperatures that may be generated inside the lamp from igniting the flammable gases and dust in the surrounding environment, thereby achieving explosion-proof lamps. Obviously, the packaging and design requirements of this type of lamps are very strict. At the beginning of product design, we strictly take into account the overall separation design, improve the explosion-proof safety level at Ⅲ C, and can meet the use in environments such as flying catkins and conductive dust. In view of this, the present invention is specially proposed. Utility Model Content

[0005] The light source cavity and the power connection compartment are arranged in the same shell with different cavities, the light source cavity and the lower cover are connected by a flameproof explosion-proof structure; the power connection compartment and the upper cover are connected by a flameproof explosion-proof structure.
[0006] The power supply of the power connection compartment is led out from the top of the upper cover. The power line passes through the sealing ring. A gasket is arranged above the sealing ring. The gasket is pressed into the upper cover for fastening through an explosion-proof compression nut.
[0007] A backup power supply is also arranged in the upper cover.
[0008] The upper cover is provided with a grounding bolt.
[0009] The shell is also provided with a lifting lug, and the lifting lug is connected to a mounting bracket.
