Problems solved by technology

Since the key lock cylinder is located on one side of the number lock cylinder, the width of the lock is still very large
In addition, the key lock cylinder must additionally drive a brake to move to control whether the inner wheel of the number lock cylinder can move, thereby indirectly controlling whether the lock hook can be opened, so the structure is relatively complicated

Abstract

The invention relates to a duplex lock which comprises a lock shell, a latch hook, a combination lock core and a key lock core. The latch hook can be movably arranged in the lock shell and includes a control part, a hook part and a root part. The control part is arranged in the lock shell. The hook part is connected with one end of the control part and extends outside the lock shell. The root part is connected with the other end of the control part and arranged in the lock shell. The combination lock core is arranged in the lock shell, and the motion of the control part can be controlled by dialing. The key lock core is arranged in the lock shell and can be driven by a matched key, so as to control the root part to move. In an example, the duplex lock further comprises an identifying component. The lock shell is provided with a window. The identifying component includes a rod and a knob. The rod can be rotationally hinged in the lock shell, and is provided with at least a side surface which can be seen from the window; the knob is arranged outside the lock shell and can drive the rod to rotate.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a double lock that can be opened by dialing or a key. Background technique [0002] China Taiwan Patent No. M247654 shows a double lock, which mainly includes a lock case, a shackle, a number lock cylinder, and a key lock cylinder. Because the number lock core and the key lock core respectively control the hook portion and the root portion of the lock hook, and are arranged side by side in the lock housing, the width of the double lock is relatively large. In addition, the key lock cylinder must additionally drive a driven unit to rotate to cooperate with the hook portion of the shackle to perform opening and locking actions, so the structure is relatively complicated. [0003] The U.S. No. 6877345 patent case shows another kind of double lock, and it is to directly control the hook portion of a shackle with a number lock cylinder, and indirectly controls the root of this shackle ...
