The invention provides an automatic springback mechanism and an aircraft folding door, and belongs to the technical field of aviation technology living facility systems.The plug in the automatic springback mechanism is provided with a hole and connected with one end of an elastic piece in a limiting pipe, the other end of the elastic piece is connected with a steel cable, and the steel cable connects the limiting pipe with a shifting seat through a second rolling wheel; the shifting seat is arranged on the folding door; the first roller carrier fixes a first roller; the second roller is erected on a guide rail above the folding door and is fixed; the steel cable penetrates through the limiting pipe, and the stress direction is changed through the first roller and the second roller. When the folding door is opened, the shifting seat moves towards the door closing direction, the steel cable stretches the elastic piece, the elastic piece overcomes the stretching force of the spring and generates downward pulling force on the steel cable, the shifting seat returns to the initial position when the folding door is closed through the first roller and the second roller, and the folding door is driven to be closed. According to the invention, waste gas in the toilet can be prevented from being discharged into the cabin when the folding door of the toilet is not closed in place, and the comfort of personnel on board can be improved.

    本发明提供一种可自动回弹机构及飞机折叠门,属于航空技术生活设施系统设计技术领域,该可自动回弹机构中堵头上开孔并与限位管中弹性件一端连接,弹性件另一端与钢索连接,钢索通过第二滚轮将限位管和拨座连接,拨座设于折叠门上;第一滚轮架固定第一滚轮;第二滚轮架设于折叠门上方导轨,固定第二滚轮;钢索穿过限位管,通过第一滚轮和第二滚轮改变其受力方向;折叠门打开时,拨座向门关闭方向移动,钢索将弹性件拉伸,弹性件为克服弹簧拉伸力,对钢索产生向下的拉力,通过第一滚轮和第二滚轮,拨座恢复至折叠门闭合时初始位置,带动折叠门关闭。本发明可避免卫生间折叠门未关闭到位使卫生间废气排进舱内,可提高机上人员的舒适感。
