Abstract
The invention discloses an air pressure balancing device, which comprises a wiring base, a sealing gasket, a screw, an elastic pad, a flat pad and a fastening hole. The invention further discloses an explosion-proof lamp, which comprises a housing, a transparent lamp cylinder, an outer cover, an inner cover, an end cover, and the air pressure balancing device. The air pressure balancing device and the lamp with the air pressure balancing device enable a C-level explosion-proof grade and meanwhile make the air pressure inside the lamp reduced during an assembling process. A balance is then maintained between the air pressure in a sealed inner chamber of the lamp and the outside air pressure. The lamp is then convenient to assemble. During a dismounting process, the air pressure inside the lamp is increased so as to keep a balance between the air pressure in the sealed inner chamber of the lamp and the outside air pressure. The lamp is then made convenient to dismount.
