a housing: the inside of casing is cavity, and the casing includes transparent fire prevention PC layer, light diffusant layer and antistatic agent layer, the side on transparent fire prevention PC layer and the medial surface fixed connection on light diffusant layer, the side on light diffusant layer and the medial surface fixed connection on antistatic agent layer, the lower surface equidistance of casing is provided with six fixed screws, the last fixed surface of casing lower surface and rubber circle is connected, and the lower surface of rubber circle is equipped with the through-hole with six fixed screw one-to-ones, can break down and when lighting a fire at the alarm lamp through transparent fire prevention PC layer, to the effective separation of flame, through the light transmissivity of the multiplicable casing of light diffusant layer, increase the luminance of alarm lamp, can effectually prevent through antistatic agent layer that the casing from producing static, guarantee the stability of alarm lamp electrical property.

Further, still include connecting rod, rotor plate, sponge strip and slide, the slide is the annular, and the slide is established in the side of casing lower extreme, the lower extreme of connecting rod rotates with the middle part of casing upper surface to be connected, the lower surface of rotor plate upper end and the upper end fixed connection of connecting rod, the lower extreme and the slide sliding connection of rotor plate, the sponge strip is established at the medial surface of rotor plate, and the medial surface of sponge strip contacts with the side of casing, can conveniently drive the sponge strip through promoting the rotor plate and rotate the outside of carrying out quick clearance to the casing, prevents that the adnexed dust in the protection casing outside from influencing the light transmissivity of protection casing.

Compared with the prior art, the beneficial effects of the utility model are that: this prevent static protection casing has following benefit:

1. can break down and when the fire at the alarm lamp through transparent fire prevention PC layer, to the effective separation of flame, through the light transmissivity of the multiplicable casing of light diffusant layer, increase the luminance of alarm lamp, can effectually prevent through antistatic agent layer that the casing from producing static, guarantee the stability of alarm lamp electric property.

2. Can conveniently drive the sponge strip through promoting the rotor plate and rotate and carry out quick clearance to the outside of casing, prevent that the adnexed dust in the protection casing outside from influencing the light transmissivity of protection casing.
