Locking mechanism for helicopter sliding window and sliding window thereof

CHEN JINHONG / LIU BIN / MA CHUNHAO

The invention relates to the technical field of aviation, in particular to a locking mechanism for a helicopter sliding window and the sliding window thereof. The locking mechanism comprises a lock hook assembly, the lock hook assembly comprises a lever component and a lock hook component, the lock hook component is used for being buckled with and separated from a lock point on the engine hood, the lever component is rotationally connected with the engine hood, one end of the lever component is fixedly connected with the lock hook component, and the other end of the lever component is transversely rotated to enable the lock hook component to be buckled with and separated from the lock point; a handle member; one end of the linkage assembly is connected with the lever part, the other end of the linkage assembly is connected with the handle part, and when the handle part is pulled vertically, the linkage assembly is used for driving the lever part to rotate transversely; according to the rotary buckling mode, the engine hood is connected in a narrow space in a locking structure mode, the engine hood can be opened and locked only by pulling the handle component, the time for disassembling and installing the engine hood is greatly saved, the overall maintenance time is saved, and the maintenance efficiency is higher.

本发明涉及航空技术领域，特指一种用于直升机滑动窗的锁闭机构及其滑动窗；锁闭机构包括：锁钩组件，包括杠杆部件和锁钩部件，锁钩部件用于与发动机罩上的锁点扣合和脱离，杠杆部件与发动机罩转动连接，杠杆部件的一端与锁钩部件紧固连接，横向转动杠杆部件的另一端使锁钩部件与锁点扣合和脱离；手柄部件；和联动组件，其一端与杠杆部件连接，其另一端与手柄部件连接，竖向扳动手柄部件时，联动组件用于带动杠杆部件横向转动；该转动扣合方式，实现了在狭小的空间内，通过锁闭结构的方式连接发动机罩，并且只需要扳动手柄部件即可打开和锁紧发动机罩，大大节省了拆开和安装发动机罩的时间，节省了整体检修时间，检修效率更高。
