The invention belongs to the technical field of airplane cabin door structure deformation compensation structure design, and particularly relates to a cabin door structure deformation compensation structure which comprises a door frame located on a tail belly, two side cabin doors hinged to the two side door frames respectively and a middle cabin door hinged to the rear door frame. A hinged shaft of the middle cabin door is vertical to the course; wherein the edges of the side cabin doors are provided with a plurality of lock rings, and the two edges of the middle cabin door are provided with a plurality of lock hooks for hooking the lock rings; when the cabin doors are opened, the two side cabin doors rotate downwards along the hinge shaft, the middle cabin door rotates upwards along the hinge shaft, and the lock hook hooks the lock ring; when the cabin doors are closed, the two side cabin doors rotate upwards along the hinge shaft, the middle cabin door rotates downwards along the hinge shaft, and the lock hook is separated from the lock ring.
本申请属于飞机舱门结构变形补偿结构设计技术领域,特别涉及一种舱门结构变形补偿结构,位于尾部机腹的门框、分别铰接在两侧门框的两个侧边舱门、铰接后门框上的中间舱门,侧边舱门的铰接轴平行于航向,中间舱门的铰接轴垂直于航向;其中,侧边舱门边缘具有多个锁环,中间舱门两边缘具有多个勾住所述锁环的锁钩;打开舱门时,两个侧边舱门沿铰接轴向下转动,中间舱门沿铰接轴向上转动,锁钩勾住锁环;关闭舱门时,两个侧边舱门沿铰接轴向上转动,中间舱门沿铰接轴向下转动,锁钩脱离锁环。
