Civil air defense door
The invention relates to a civil air defense door and belongs to the field of civil air defense engineering, the civil air defense door comprises a civil air defense door body, rollers are fixedly arranged at the bottom of the civil air defense door body, a first supporting plate and a second supporting plate are hinged to the bottom of the civil air defense door body, the opposite sides of the first supporting plate and the second supporting plate are hinged to the civil air defense door body, and the close sides of the first supporting plate and the second supporting plate are arranged as free ends; a cavity is formed in the position, close to the bottom, in the civil air defense door body, a top block is vertically and slidably connected into the cavity, and a driving assembly for driving the top block to vertically move to push the first supporting plate and the second supporting plate to be overturned to abut against the ground is arranged at the top of the top block. The rolling wheel has the effects of reducing the load bearing of the rolling wheel and prolonging the service life of the rolling wheel.
本申请涉及一种人防门，属于人防工程的领域，其包括人防门本体，人防门本体的底部固设有滚轮，所述人防门本体的底部铰接有支撑板一和支撑板二，支撑板一和支撑板二相背的一侧与人防门本体铰接，相近的一侧呈自由端设置，人防门本体内靠近底部的位置开设有空腔，空腔内竖向滑移连接有顶块，顶块的顶部设置有驱动顶块竖向运动推动支撑板一和支撑板二翻转至抵接于地面的驱动组件。本申请具有减小滚轮的承重、延长滚轮的使用寿命的效果。
