102 are switched, and have the advantages of suction intensity is high, and power supply energy consumption is low, anti-external world, have double protection to fire resistant doorsets,
Improve the effect of fire resistant doorsets heat-insulating, fire-preventing.
Operation principle：First, by the way that puigging 1013 and thermal insulation layer 1014 are arranged in fire resistant doorsets to improve fire resistant doorsets
The effect of sound-insulating and heat-insulating, 1013 surface of puigging are in " wave " shape, can largely absorb the sound wave of injection, decaying is played to sound wave
Effect hinders the propagation of noise, and has to fire resistant doorsets by the thermal insulation layer 1014 that magnesium silicon fire-proof plate and perlite fireproof plate form
There are high temperature resistant, the effect of sound insulation damping and heat-insulating flame-retardant, keep fire resistant doorsets more practical, then fire resistant doorsets are risen by rolling screen door 102
To the effect of double protection, effectively increase fire protecting performance, then by the fire-proof expansion seal strip of 102 both sides of rolling screen door with
The rising of temperature and expand, block the gap of crack between a door and its frame, obstruct the air circulation between two spaces, effectively prevent in fire
The dense smoke of generation forms barrier, while electromagnetic type rolling screen door lock 1021 can be square by being electrically connected with motor of rolling shutter door 1022
Just rolling screen door 102 is switched, substantially increases the effect of fire resistant doorsets heat-insulating, fire-preventing, and then open manual rotation pin lock
1011 pairs of cervicals orifice of uterus 101 switch, and quickly open cervical orifice of uterus 101, people is facilitated to make disengaging the case where normally can not open gate,
Facilitate escape, cervical orifice of uterus 101 is fixed in doorframe 1 finally by the keeper 1012 in " L " shape, is fixed when not in use
Firmly, it avoids by external impact and 101 door-plate of cervical orifice of uterus is caused to damage, ensure that the normal use of cervical orifice of uterus.
The above are merely the preferred embodiment of the present invention, it is noted that for those skilled in the art, not
Under the premise of being detached from present inventive concept, several modifications and improvements can also be made, these should also be considered as the protection model of the present invention
It encloses, these all do not interfere with the effect and patent practicability that the present invention is implemented.
