The invention discloses a mechanical door-opening lift car lock safety mechanism. The mechanical door-opening lift car lock safety mechanism comprises a spinning movement mechanism, a linkage shifting block and a stop block, wherein an actuating rod is arranged on the spinning movement mechanism in a horizontal extending mode; the upper portion of the linkage shifting block is fixed to the bottom of the outer side wall of a car door; the lower end of the linkage shifting block downwards extends to be as high as the actuating rod; the stop block is disposed at the lower end of a hoistway door sill, and a long strip groove is transversely designed in the center of the stop block; during opening of the car door, the actuating rod spins outwards, and the free end of the actuating rod gradually spins to enter the groove till the free end is stopped against the inner side wall of the groove; during closing of the car door, the linkage shifting block shifts the actuating rod to spin inwards, and the free end of the actuating rod is gradually separated from the groove. According to the mechanical door-opening lift car lock safety mechanism, injury accidents caused by accidental ascending or descending during door opening and closing of a lift car can be effectively avoided.
