The invention relates to the technical field of aircraft cabin doors, in particular to a door-ladder integrated gangway ladder door. The door-ladder integrated gangway ladder door comprises a door frame; an upper cabin door and a lower cabin door are rotationally arranged in the door frame; a throwing mechanism is arranged outside the door frame in a surrounding mode. Unlocking mechanisms are respectively arranged on the inner sides and the outer sides of the upper cabin door and the lower cabin door; a step mechanism is arranged on the inner side of the lower cabin door; a passive auxiliary folding and unfolding device is also arranged between the lower cabin door and the door frame in a transmission manner. The door-ladder integrated gangway ladder door is reasonable and ingenious in overall structural design; the cabin door can be easily and conveniently opened and closed no matter inside or outside a cabin; the stability is high, the structure is stable, the throwing mechanism is not prone to damage, one-key throwing of the overall cabin door can be achieved through the design, and the safety performance is greatly improved. Due to the design of the step mechanism, the space issaved, the structural design of the cabin door is fully utilized, and the practical performance is greatly improved. The design of a damping rod can improve the stability and prevent the lower cabindoor from being damaged.
本发明涉及飞机舱门技术领域,具体涉及一种门梯合一式舷梯门,包括门框,门框内转动设置有上舱门和下舱门,门框的外部环绕设置有抛放机构,上舱门和下舱门的内外侧上均分别设置有解锁机构,下舱门的内侧上设置有阶梯机构,下舱门与门框之间还传动设置有无源辅助收放装置,发明一种门梯合一式舷梯门,整体结构设计合理巧妙,无论在舱内或是舱外都可以轻松方便地对舱门进行打开和关闭,同时稳定性高,结构稳定,不容易发生损坏抛放机构的设计使得整体舱门能够实现一键抛放,大大提高了安全性能。阶梯机构的设计也节省了空间,充分利用了舱门本身的结构设计,大大提高了实用性能。阻尼杆的设计可以提高稳定性,防止下舱门发生损坏。
