Locking mechanism for front cabin door and rear cabin door
The invention provides a front and rear cabin door locking mechanism which comprises an outer handle assembly, an inner handle assembly and a lock pin assembly which are arranged on a cabin door, and a lock seat assembly which is arranged on a cabin door frame, the outer handle assembly comprises an outer lock disc, an outer handle and a swing arm connecting rod mechanism driven by the outer handle, the swing arm connecting rod mechanism is in linkage with the inner handle assembly and the lock pin assemblies, the number of the lock pin assemblies and the number of the lock seat assemblies are multiple, and lock pins of the multiple lock pin assemblies synchronously stretch out and retract under driving of the swing arm connecting rod mechanism. At least one set of lock pin assembly further comprises a limiting mechanism, and the limiting mechanism can limit the lock pin of the lock pin assembly when the lock pin retracts, and release limiting of the lock pin when the lock pin is collided by the corresponding lock seat and overcomes limiting resistance. According to the locking mechanism for the front cabin door and the rear cabin door, unlocking between the multiple sets of lock pin assemblies and the corresponding lock seat assemblies can be achieved through the outer handle or the inner handle, operation is convenient, the control effect is good, and the locking mechanism can be applied to a cockpit door and a passenger cabin door of a helicopter.
本发明提供了一种前后舱门锁闭机构，包括用于设置在舱门上的外把手组件、内把手组件和锁销组件、以及用于设置在舱门门框上的锁座组件；外把手组件包括外锁盘、外把手、以及由外把手带动的摆臂连杆机构，摆臂连杆机构与内把手组件和锁销组件联动，锁销组件和锁座组件均为多组，多组锁销组件的锁销在摆臂连杆机构带动下同步伸出和缩回，至少一组锁销组件还包括限位机构，限位机构能在所在锁销组件的锁销缩回时对其限位、以及在被对应的锁座碰撞且克服限位阻力时解除对锁销的限位。本前后舱门锁闭机构能通过外把手或内把手实现多组锁销组件和对应的锁座组件之间的解锁，操作方便，控制效果良好，可应用在直升机的驾驶舱门和客舱门上。
