A retractable household rescue cabin for urban disaster environment

Abstract

The invention discloses a retractable domestic rescue capsule for an urban disaster environment. The retractable domestic rescue comprises a fixed part, a retractable part and a capsule door part. When the dangerous case occurs, refuge personnel pull a push-pull handle, thus the retractable part moves along U-shaped guide rails to be in an extending state so as to provide a sufficient refuge spacefor the refuge personnel; and meanwhile, the refuge personnel can close a capsule door through a rotating disc, through a wedge mechanism on a spur rack, the capsule door and a capsule body can be clamped, and thus the air tightness of the interior of the rescue capsule is ensured. Through combination of the fixed part, the retractable part and the capsule door part, the sufficient internal spaceof the rescue capsule under the emergency situation is ensured while the floor space of the domestic rescue capsule during daily placing is reduced, it is further ensured that the interior of the rescue capsule has the good air tightness, and a safe refuge space can be provided for the refuge personnel.
