The invention relates to a blocking mechanism, a lockset and a locking device, and belongs to the technical field of locking instruments. The blocking piece is used for blocking the lock pin linkage piece when the lock pin retracts to the unlocking position in the unlocking direction, and the blocking piece at least can rotate between a first position where the lock pin linkage piece passes and a second position where the lock pin linkage piece is blocked after passing; rotating the reset piece; and a locking trigger. After the lock is unlocked, the lock pin is kept at the unlocking position through blocking and limiting of the lock pin, and the locking action is achieved by canceling blocking and limiting of the lock pin in the cockpit door closing process. Therefore, the lock pin does not need to collide with other parts to achieve the locking action, the possibility of abrasion and damage of the lock pin can be effectively reduced, and the service life of the lock pin can be greatly prolonged.
本发明涉及一种阻挡机构、锁具以及锁闭装置,属于锁闭器械技术领域,所述阻挡机构包括:锁销联动件;阻挡件,用于在所述锁销沿解锁方向回缩至解锁位置时对所述锁销联动件进行阻挡,所述阻挡件至少可在让所述锁销联动件通过的第一位置与让所述锁销联动件通过后被阻挡的第二位置之间转动;转动复位件;以及锁闭触发件。本发明在锁具解锁后通过对锁销的阻挡限位使其保持在解锁位置,在驾驶舱门关闭过程中撤销对锁销的阻挡限位来实现锁闭动作。因此,无需锁销与其它部件进行撞击来实现锁闭动作,能够有效降低锁销的磨损和锁销损坏的可能性,从而能够大大提升锁销的使用寿命。
