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.

Description of drawings
Fig. 1 is the explosion-proof lamp structural representation of one embodiment of the present invention;
Fig. 2 is the A portion enlarged drawing of the explosion-proof lamp of a kind of embodiment shown in Figure 1.
The specific embodiment
For purpose, technical scheme and the advantage of the device that makes equilibrium air pressure of the present invention are clearer,, the device of equilibrium air pressure of the present invention is further elaborated below in conjunction with concrete accompanying drawing and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Like Fig. 1, shown in Figure 2, the device of equilibrium air pressure of the present invention comprises wiring pedestal 11, sealing gasket 12, securing member 13, bullet pad 14, plain cushion 15 and fastener hole 16.
Sealing gasket 12 is provided with and can matees the circular hole that holds said securing member 13; Plain cushion 15 is provided with and can matees the circular hole that holds securing member 13; Bullet pad 14 is provided with and can matees the circular hole that holds securing member 13; Securing member 13 passes bullet pad 14 successively, and the circular hole on plain cushion 15 and the sealing gasket 12 is fixed in the fastener hole 16.
Securing member 13 can be various fastening components and parts such as screw, bolt; Fastener hole 16 is the screw hole that matches or bolt hole etc.
Preferably, but as a kind of embodiment, said securing member 13 is a screw; Said fastener hole 16 is a screw hole; Securing member 13 passes bullet pad 14 successively, and the circular hole on plain cushion 15 and the sealing gasket 12 is screwed in the fastener hole 16, and in order to guarantee the requirement of explosion proof of light fixture, securing member 13 is buckled greater than 5 with the number of buckleing of screw-threaded engagement.
