Locking mechanism for aircraft engine cabin door
The invention relates to the technical field of aviation, in particular to a locking mechanism for an aircraft engine cabin door. Comprising a main lock mechanism and an auxiliary lock mechanism. The main lock mechanism is used for locking an engine cabin door in the flight direction of an aircraft and comprises a first lock hook part, a first lock hook part is arranged at one end of the first lock hook part, and when the first lock hook part moves forwards, the first lock hook part is separated from a first lock point of an engine hood and when the first lock hook part retracts, the first lock hook part is buckled with the first lock point of the engine cabin door. The auxiliary lock mechanism is used for locking the engine cabin door in the opening direction of the engine cabin door; comprising a lever part and a second lock hook part, the lever part is rotationally connected with the engine hood, one end of the lever part is fixedly connected with the second lock hook part, and the lever part transversely rotates to drive the second lock hook part to be buckled with or separated from a second lock point of the engine cabin door; due to the combination of the main lock mechanism and the auxiliary lock mechanism, the locking effect is better; the cabin door and the engine hood are connected through the locking structure in a narrow space, and the overall maintenance time is saved.
本发明涉及航空技术领域，特指一种用于飞机发动机舱门的锁闭机构；包括主锁机构和副锁机构；主锁机构用于在飞机的飞行方向锁住发动机舱门，其包括第一锁勾部件，第一锁勾部件的一端设有第一锁勾部，第一锁勾部前移时，与发动机罩的第一锁点分离，第一锁勾部回缩时，与发动机舱门的第一锁点扣合；副锁机构用于在发动机舱门的打开方向锁住发动机舱门；包括杠杆部件和第二锁钩部件，杠杆部件与发动机罩转动连接，杠杆部件的一端与第二锁钩部件紧固连接，杠杆部件横向转动，带动第二锁钩部件与发动机舱门的第二锁点扣合或脱离；主锁机构和副锁机构的组合，使锁闭效果更好；实现了在狭小的空间内通过锁闭结构连接舱门和发动机罩，节省了整体检修时间。
