Double-lock device of aircraft cabin door latch mechanism
The invention belongs to the design technology of aircraft cabin door mechanisms, and particularly relates to an aircraft cabin door latch mechanism double-lock device which comprises a lock mechanism rotating shaft, a latch mechanism rotating shaft, a first latch hook, a second latch hook and a pull rod, one end of the pull rod is hinged to a sequence control mechanism, and the other end of the pull rod is hinged to the support arm of the lock mechanism rotating shaft. When the latch mechanism rotating shaft rotates by a preset angle, the latch mechanism rotating shaft latches the cabin door; during locking, the sequence control mechanism drives the lock mechanism rotating shaft to rotate through the pull rod and the support arm, so that the first lock key and the first lock hook are engaged and locked, and the second lock key and the second lock hook are engaged and locked; during unlocking, the sequence control mechanism drives the lock mechanism rotating shaft to rotate, the first lock key is separated from the first lock hook, and the second lock key is separated from the second lock hook, the double-lock device is adopted, the failure rate of the lock mechanism is greatly reduced, double locking of the latch mechanism is achieved, and the reliability of the cabin door locking state is greatly improved.
本申请属于飞机舱门机构设计技术，特别涉及一种飞机舱门闩机构双锁装置，包括：锁机构转轴，其具有第一锁键，第二锁键以及支臂，闩机构转轴，其具有第一锁钩与第二锁钩，拉杆，其一端铰接顺序控制机构，另一端铰接锁机构转轴的支臂上；其中，闩机构转轴旋转预设角度时，闩机构转轴对舱门上闩；上锁时，顺序控制机构通过拉杆、支臂驱动锁机构转轴旋转，使第一锁键与第一锁钩啮合锁止，使第二锁键与第二锁钩啮合锁止；开锁时，顺序控制机构驱动锁机构转轴旋转，第一锁键与第一锁钩、第二锁键与第二锁钩脱开，采用双锁装置，大大降低了锁机构的失效率，实现了闩机构的双重锁定，极大提高了舱门锁闭状态的可靠性。
