The invention relates to the technical field of stair descending devices, in particular to a quick descending device for a safety stair. The invention provides a quick descending device for a safety stair, which can realize quick moving escape. A rapid descending device for a safety stair comprises a base plate, friction rings, an upper rail mechanism and a lower rail mechanism, the upper portion and the lower portion of the base plate are evenly connected with the multiple friction rings in a sliding mode at intervals, the upper rail mechanism is connected between the friction rings on the upper portion, and the lower rail mechanism is connected between the friction rings on the lower portion. According to the invention, the hand-fixing grabbing rods at the upper side and the lower side can be selected to be grabbed according to the height, then feet are placed between the sliding seat and the foot-fixing belt, then a user can be supported to slide down, when the user is short, the screw rod can be controlled to rotate, so that the height of the foot rail is adjusted, and the user can control the hand-fixing grabbing rods and pull the hand-fixing grabbing rods to the front side in the down-sliding process; therefore, the friction seat rotates and does not make contact with the handrail rail any more, and then fast descending is achieved.
本发明涉及楼梯下行装置技术领域,尤其涉及一种安全楼梯快速下行装置。本发明提供一种能够实现快速移动逃生的安全楼梯快速下行装置。一种安全楼梯快速下行装置,包括有基板、摩擦环、上轨机构和下轨机构,基板的上下两部均均匀间隔的滑动式连接有多个摩擦环,上部的摩擦环之间连接有上轨机构,下部的摩擦环之间连接有下轨机构。本发明能够根据身高来选择抓住上下两侧的固手抓杆,然后脚放置在滑座与固脚带之间,随后便能够对使用者进行支撑下滑,使用者身高较矮时,可控制丝杆旋转,从而调整足轨高度,在下滑过程中,使用者能够控制固手抓杆并向前侧拉动,从而使得摩擦座旋转不再与栏杆轨接触,进而做到快速下行。
