The linkage type emergency alarm device comprises a box body, a light supplementing groove, an air detection box and a third cavity, the light supplementing groove is formed in the top of the box body, the air detection box is installed on the outer wall of the box body, a linkage box is installed on the inner wall of the first cavity, a detection cavity is installed on the inner wall of the air detection box, and the detection cavity is communicated with the linkage box. And a photoreceptor is mounted at the top of the box body. Light supplementing can be conducted by installing a photoreceptor and a light supplementing groove, when an elevator breaks down, the resistance value of a photoresistor changes, then a motor is started, the motor rotates to drive a driving gear to rotate, the driving gear rotates to drive a gear groove to move, the gear groove moves to drive a lifting rod to move, and the lifting rod moves upwards to drive a circuit board to move; the circuit board moves to drive the protective cover to move upwards, the protective cover makes contact with the rolling wheels, then the shielding plate is extruded, the shielding plate does not shield the protective cover any more, and therefore the LED lamp can emit light outwards, and the lighting function is achieved.
本发明公开了一种电梯轿厢用的联动式应急报警装置,包括箱体、补光槽、空气检测箱和三号腔,所述箱体的顶部设有补光槽,所述箱体的外壁安装有空气检测箱,所述一号腔的内壁安装有联动箱,所述空气检测箱的内壁安装有检测腔,所述箱体的顶部安装有感光器。本发明通过安装有感光器和补光槽可以进行补光,当电梯发生故障时,光敏电阻的阻值发生变化,随后启动马达,马达转动带动驱动齿轮转动,驱动齿轮转动带动齿轮槽移动,齿轮槽移动带动升降杆移动,升降杆向上移动带动电路板移动,电路板移动带动保护罩向上移动,保护罩与滚轮接触,随后挤压遮挡板,使得遮挡板不再对保护罩进行遮挡,从而使得LED灯可以向外发光,实现照明功能。
