The invention belongs to the technical field of automatic control of aviation lifesaving equipment, and relates to a mechanical unlocking device with a dual-redundancy locking mechanism. Comprising a sector gear, a brake pad, a transmission gear, a transmission pinion, a transition pinion, a transition gear, a pinion, an adjusting wheel, an adjusting swing sheet, a balance wheel, a push rod shaft, a lock rod, a push rod, a transmission block, a lower flat plate, a brake pad shaft, an adjusting screw, a driving lever, a deflector rod, a lever, a lock claw and an upper flat plate. On the basis of a traditional unlocking device, the locking mode of the starting pull pin is improved, the locking mode of the balance wheel is improved by additionally arranging the push rod and the lock rod, and locking is more reliable; meanwhile, the combination of the transmission block and the adjusting sliding block is added, it is guaranteed that the locking gap of the balance wheel is adjustable, abrasion of the starting pull pin is reduced through the pulley, and the service life of the starting pull pin is prolonged.

    本发明属于航空救生装备的自动控制技术领域,涉及一种具有双余度锁紧机构的机械式开锁器。包括扇形齿轮、制动片、传动齿轮、传动小齿轮、过渡小齿轮、过渡齿轮、小齿轮、调节轮、调节摆片、平衡轮、推杆轴、锁杆、推杆、传动块、下平板、制动片轴、调节螺钉、主动杠杆、拨杆、杠杆、锁爪和上平板;本发明在传统开锁器的基础上改善了启动拔销的锁紧方式,通过增加推杆和锁杆改善了平衡轮的锁紧方式,使锁紧更可靠;同时增加了传动块和调整滑块组合,既保证平衡轮的锁紧间隙可调,又通过滑轮降低启动拔销的磨损,提高了启动拔销的使用寿命。
