The invention provides a cabin door of a pressurized cabin, and belongs to the technical field of aviation. During unlatching and unlocking, a handle drives a main shaft to rotate, the main shaft drives a pressure relief valve to be opened, meanwhile, a main shaft driving lock is unlocked, and when the main shaft continues to rotate until a time-sharing driving rocker arm is in contact with an open type guide groove of the time-sharing rocker arm, the time-sharing rocker arm starts to drive a bolt latch to be unlatched; unlatching is completed; on the contrary, when the upper latch is locked, the handle drives the main shaft to rotate, the main shaft drives the time-sharing rocker arm to rotate, the time-sharing rocker arm drives the bolt latch to be latched until the time-sharing driving rocker arm is separated from the open type guide groove of the time-sharing rocker arm, unlatching is completed, and then the main shaft continues to drive the pressure relief valve to be closed and drive the lock to be locked until the pressure relief valve is completely closed and the lock is locked; the mechanism principle is simple, the weight is light, the reliability of the cabin door is improved, and meanwhile the use range of the mechanism is enlarged through reasonable arrangement of the mechanism principle and the adoption of the bolt latch.

    本申请提供一种增压舱舱门,属于航空技术领域,解闩解锁时,手柄驱动主轴转动,主轴驱动释压活门打开,同时主轴驱动锁解锁,主轴继续转动到分时驱动摇臂与分时摇臂的开口式导向槽接触时,然后分时摇臂开始驱动插销闩解闩,直到解闩完成;反之,上闩上锁时,手柄驱动主轴转动,主轴驱动分时摇臂转动,分时摇臂驱动插销闩上闩,直到分时驱动摇臂与分时摇臂的开口式导向槽分离时,解闩完成,然后主轴继续驱动释压活门关闭及驱动锁上锁,直到压活门完全关闭和锁锁定;机构原理简单、重量轻,提高了舱门的可靠性,同时通过机构原理的合理布置及采用了插销闩的形式,增大了机构的使用范围。
