ABSTRACT:
A hanging lock structure including a lock body and a lock hook. The lock body is formed with two lock holes. A numeral unlocking unit is disposed in the lock body corresponding to one of the lock holes. Each lock hole is composed of a larger insertion hole and a narrower slot communicating with the insertion hole. Two stop blocks are disposed in the lock body respectively corresponding to the lock holes. The lock hook has two free ends which are movable relative to each other. Each free end has an insertion head. The insertion heads of the free ends of the lock hook can be respectively inserted in the lock holes and controlled by the two unlocking units. When the stop blocks are such positioned as to block the insertion holes, the insertion heads are restricted within the slots to achieve a locking effect. Any of the numeral unlocking unit and the key-unlocking unit can drive any of the stop blocks to unblock any insertion hole so as to release any free end of the lock hook. Therefore, the hanging lock is double-unlockable.
