A new type of sliding rail type civil air defense door
This utility model provides a novel sliding rail-type air-raid shelter door, relating to the technical field of air-raid shelter door equipment. It includes a fixed base plate, on the top of which are installed a first security wall and a second security wall. By setting up the fixed base plate, the first security wall, and a limiting mechanism, and using auxiliary lighting with a lamp, it facilitates nighttime operations. The second limiting frame contains an installation clamp plate and a limiting roller of the same structure. The limiting roller limits the sliding trajectory of the air-raid shelter door. A third positioning bolt positions the installation sleeve plate and the movable slider, ensuring that when the air-raid shelter door slides, it drives the fixed block to slide to one side. With the connection of the connecting rod, the movable slider slides outside the installation frame, the limiting roller rolls on one side of the installation frame, and the movable slide plate slides inside the positioning frame. This achieves normal security while facilitating remote monitoring of the site. Multiple limiting sliding mechanisms prevent excessive speed during sliding, thus avoiding safety hazards, and also facilitate subsequent normal resetting.
