The invention discloses a hook-type lock safety mechanism for an aviation cockpit. The hook-type lock safety mechanism comprises a lock ring, a lock hook, a connecting sheet, a rocker arm, a connection rocker arm and a locking and pulling rod, wherein one end of the lock hook is used for locking the lock ring; the other end of the lock hook is hinged with one end of the connecting sheet; the other end of the connecting sheet is hinged with one end of the rocker arm; the other end of the rocker arm is hinged with one end of the connection rocker arm; a boss is arranged on the connection rocker arm; the other end of the connection rocker arm slides in a U-shaped groove of the locking and pulling rod; a small platform is formed below the U-shaped groove of the locking and pulling rod; and a protruding ejection block is arranged at the connection portion of the connecting sheet and the rocker arm. According to the safety mechanism, under the condition that parts are not increased, only corresponding structures are added to original components; and after locking is realized in place by the lock hook, the lock hook is prevented from rotating continuously and pressing the lock ring, and the lock hook is also prevented from being stressed to rotate clockwise and unlock the look.
