The invention provides a side-hung type cabin door mechanism capable of being mechanically released in emergency, and belongs to the technical field of airplane cabin doors. The emergency rope is connected to the operating handle, and the other end of the emergency rope is connected to the first gear set; two gears of the first gear set are respectively arranged on the fuselage structure and the small cabin door, and two gears of the second gear set are respectively arranged on the actuating cylinder rocker arm and the cabin door rocker arm; the cabin door actuating cylinder is used for driving the cabin door to be normally opened and connected with an actuating cylinder rocker arm which is connected with the large cabin door, and the large cabin door is hinged to the small cabin door; when the cabin door is normally opened, the cabin door actuating cylinder drives the actuating cylinder rocker arm, then the cabin door rocker arm is driven to move through the second gear set, and finally the large cabin door and the small cabin door are driven to rotate to the completely-opened position. When the cabin door is released emergently, the operation handle is pulled, the first gear set is pulled to rotate through the emergency rope, and the small cabin door and the large cabin door are driven to rotate to the completely-opened position.
本申请提供了可机械应急释放的平开式舱门机构,属于飞机舱门技术领域,该舱门机构包括:操作手柄;连接在操作手柄上的应急绳索,其另一端连接至第一齿轮组;第一齿轮组和第二齿轮组,第一齿轮组的两个齿轮分别设置在机身结构和小舱门上,第二齿轮组的两个齿轮分别设置在作动筒摇臂和舱门摇臂上;用于驱动舱门正常打开的舱门作动筒,其连接作动筒摇臂,舱门摇臂连接大舱门,大舱门与小舱门之间铰接;当舱门正常打开时,舱门作动筒驱动作动筒摇臂,进而通过第二齿轮组驱动舱门摇臂运动,最终驱动大舱门和小舱门转动至完全打开位置;当舱门应急释放时,扳动操作手柄,通过应急绳索牵动第一齿轮组转动,驱动小舱门和大舱门转动至完全打开位置。
