Locking mechanism with limiting stopper
The invention provides a locking mechanism with a limiter. The locking mechanism comprises an outer handle assembly, an inner handle assembly, a lock pin assembly, a lock seat assembly and a cabin door limiting assembly. 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, lock pins of the multiple lock pin assemblies are driven by the swing arm connecting rod mechanism to synchronously act, and at least one lock pin assembly further comprises a limiting mechanism. The limiting mechanism can limit the lock pin when the lock pin retracts and relieve limiting of the lock pin when the lock pin is collided by the corresponding lock seat and overcomes limiting resistance, and the cabin door limiting assembly can keep the cabin door in an open state. According to the locking mechanism, synchronous 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 is suitable for being applied to passenger cabin doors of helicopters.
本发明提供一种具有限位器的锁闭机构，包括外把手组件、内把手组件、锁销组件、锁座组件、以及舱门限位组件；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德动作，至少一组锁销组件还包括限位机构，限位机构能在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，舱门限位组件能保持舱门处于打开状态。本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锁座组件之间的同步解锁，操作方便，控制效果良好，适合应用在直升机的客舱门上。
