The invention relates to the technical field of aviation, in particular to a locking mechanism for an inner cover of an aircraft engine compartment. Comprising a lock pin assembly which is installed on an engine cabin door and comprises a lock pin part, and a first locking hole is formed in the lock pin part; the lock groove assembly is installed on the engine compartment inner cover and comprises a lock groove component, and a second locking hole is formed in the lock groove component; the locking assembly comprises a lock head part, and the lock head part is perpendicular to the lock groove part; when the engine cabin door is closed, the lock pin component is partially inserted into the lock groove component, and the lock head component penetrates through the first locking hole and the second locking hole and is used for fixing the lock pin component into the lock groove component. By means of the mode of the telescopic bolt, the engine cabin door and the engine inner cover are locked in a narrow space, the engine cabin door can be unlocked only by pulling out the lock head part, then the engine cabin door is opened, the time for disassembling and installing the engine cover 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,特指一种用于飞机发动机舱内罩的锁闭机构;包括:锁销组件,安装在发动机舱门上,其包括锁销部件,该锁销部件上设有第一锁定孔;锁槽组件,安装在发动机舱内罩上,其包括锁槽部件,该锁槽部件上设有第二锁定孔;以及锁定组件,其包括锁头部件,该锁头部件与锁槽部件垂直设置;关闭发动机舱门时,锁销部件部分插入锁槽部件,锁头部件穿过第一锁定孔与第二锁定孔,用于使锁销部件固定在锁槽部件内;通过该伸缩插销的方式,实现了在狭小的空间内,锁定发动机舱门和发动机内罩,并且只需要拔出锁头部件即可解锁发动机舱门,进而打开发动机舱门,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。
