Abstract

A combined night lock with a straight key hole comprises a lock body, a lock core, a billiard, a spring, and an envelope. More than three lines of marble holes which can prevent from the master key and regular marble holes are arranged in the direction that is upright to the key hole and uprightly intersectant with the axes of the key hole. Constantly opened T-shaped billiard for the prevention of master key, constantly closed T-shaped billiard for the prevention of master key, T-shaped billiard and spring are arranged inside. The envelope is arranged outside. The same processing diameter of the marble hole is guaranteed from the manufacture craft. The diameter of the constantly opened T-shaped billiard for the prevention of master key is smaller than that of the regular marble hole, and the diameter of the constantly closed T-shaped billiard for the prevention of master key is smaller than that of the regular marble hole. While magnetic marbles are arrayed at the two ends of the key hole. When the matched key is inserted into the right position, the front end of three non-magnetism T-shaped marbles respectively drops to the relative scallops of the key. The marbles just reach the interface of the lock body and the lock core with the three non-magnetism T-shaped marbles. On the other hand, the magnetic column which is fixed on the key blackballs the magnetic marbles in relative lock marble holes off the scallops on the lock core. Then the lock is opened. The combination of the magnetic marbles and the three non- magnetism marbles provides the lock with good character to prevent from the master key with low open rate, simple manufacture craft and board market prospects.
