The invention belongs to the field of left-right opposite-opening cabin door closing position locks, and particularly relates to a left-right opposite-opening cabin door closing position lock which adopts a mechanical comprehensive butt-joint lock design, achieves control over locking and unlocking of a left cabin door and a right cabin door through an actuator cylinder and a lock key, and is good in collaboration, simple in overall structure, high in reliability, light in weight and high in reliability. Deformation and jump generation of the left-right split cabin door due to the aerodynamic load effect can be effectively inhibited, the flight resistance of an airplane is increased, the load of the driving mechanism after the left-right split cabin door is closed can be reduced, pre-tightening force does not need to be applied to the left-right split cabin door, and the fatigue life of the structure can be effectively guaranteed.

    本申请属于左右对开舱门关闭位置锁领域,具体涉及一种左右对开舱门关闭位置锁,采用机械式综合对接锁设计,以一个作动筒、锁键实现对左舱门、右舱门上锁、解锁的控制,协同性好,整体结构简洁,可靠性高,重量轻,可有效抑制左右对开舱门受气动载荷作用,发生变形,产生阶差,增加飞机的飞行阻力,且能够降低驱动机构在左右对开舱门关闭后的载荷,并无需对左右对开舱门施加预紧力,能够有效保证结构的疲劳寿命。
