Anti-misoperation mechanism of aircraft cabin door
The invention provides an aircraft cabin door anti-misoperation mechanism, and belongs to the field of aircraft cabin door mechanism design, a guide piece is fixed on an aircraft body opening frame, the lower end of a rocker arm assembly is connected with a spring assembly, and the anti-misoperation mechanism always keeps a locking trend under the action force of the spring assembly. In the cabin door lifting process, the upper locking rod is driven by the outer handle to rotate towards the upper locking position, and the rocker arm assembly and the guiding piece are attached all the time to avoid locking; in the cabin door opening process, the rocker arm assembly is separated from the guide piece, the lock assembly is interlocked, and the retainer is limited; and if the anti-misoperation mechanism is clamped, the lock assembly does not form interlocking, the cabin door is opened outwards, the rocker arm assembly rotates under the guide of the guide piece, and the lock assembly forms interlocking. The locking mechanism is reliable in locking, can prevent the cabin door in an open state from being operated by mistake, can still play a locking role under the clamping stagnation condition, is simple in structure, does not occupy the internal space of the cabin door, is good in assembling performance, and can be widely applied to various types of cabin doors.
本发明提供一种飞机舱门防误操作机构，属于飞机舱门机构设计领域，导向件固定在机身口框上，摇臂组件下端连接弹簧组件，弹簧组件的作用力使防误操作机构始终保持上锁趋势。舱门提升过程，上部锁杆在外手柄的驱动下向上锁位旋转，摇臂组件与导向件始终贴合避免锁定；舱门开启过程，摇臂组件脱离导向件，锁组件互锁，止动件限位；舱门处于提升结束位，若防误操作机构出现卡滞，锁组件未形成互锁，舱门向外打开，摇臂组件在导向件引导下旋转，锁组件形成互锁。本发明锁定可靠，能防止开启状态下的舱门被误操作，且在机构发生卡滞情况仍能够发挥锁定作用，机构简单，不占用舱门内部空间，装配性好，可以广泛应用到各种类型的舱门上。
