A safety locking mechanism for a lockset is provided, the lockset including a cover plate (8), a support plate (9), and a lock body (10). The safety locking mechanism includes a locking push rod (1), a locking stopper (2), and a locking compression spring (3). The locking push rod (1) includes a direction-limiting shaft (4) and a cylindrical rod (6), where the direction-limiting shaft (4) is mounted at one end of the cylindrical rod (6) and the other end of the cylindrical rod (6) passes through the support plate (9) and presses against the cover plate (8). The locking stopper (2) is rotatably mounted on the cylindrical rod (6) and has a front end and a back end being close against the support plate (9) and the lock body (10) respectively. The lock body (10) is provided with a direction-limiting groove. The direction-limiting shaft (4) is mounted in the direction-limiting groove. The locking compression spring (3) is mounted between the direction-limiting shaft (4) and a bottom end of the direction-limiting groove in a compressed manner. Thus, the difficulty of technical unlocking is greatly increased and the safety of the lockset is improved. |
