The invention relates to a lock, a locking mechanism and a helicopter observation window, and belongs to the technical field of aviation machinery. A lock hole; the locking reset spring is used for enabling the lock pin to have a trend of moving and resetting towards the locking position along the locking direction; the impact blocking piece is arranged on the sliding window body and is provided with a blocking position for blocking the lock pin and a blocking releasing position for allowing the lock pin to pass through; the blocking reset spring is used for enabling the blocking impact piece to have a trend of moving to the blocking position for resetting; and the impact matching part is arranged on a window frame of the sliding window body. According to the invention, the observation window can be quickly locked, and the lock pin can be partially or completely inserted into the lock hole to realize locking before collision, so that the situation that the observation window fails to be locked when an operator performs window closing action and exerts overlarge force can be prevented.
本发明涉及一种锁具、锁闭机构以及直升机观察窗,属于航空机械技术领域,其中锁具包括:锁销;锁孔;锁闭复位弹簧,用于使所述锁销具有沿所述锁闭方向向锁闭位置移动复位的趋势;阻挡撞击件,设置在所述滑动窗体上,具有让所述锁销被阻挡的阻挡位置和让所述锁销通过的解除阻挡位置;阻挡复位弹簧,用于使所述阻挡撞击件具有向所述阻挡位置移动复位的趋势;以及撞击配合部,设置在所述滑动窗体的窗框上。本发明能够实现观察窗的快速锁闭,并且锁销能够在发生碰撞之前就部分插入或完全插入锁孔内实现锁闭,因此,能够在操作者进行关窗动作施力过大时防止观察窗锁闭失败的情况出现。
