Patent attributes
A lock device for a box includes a locking shaft, a lock shell, a lock core, a limiting unit, and a key. The lock shell has a surrounding shell wall that confines a core-receiving space, and that is formed with an insert hole in spatial communication with the core-receiving space to permit removable extension of the locking shaft into the core-receiving space. The lock core is disposed movably in the core-receiving space, and has a surrounding core wall that confines a key compartment and that is formed with a shaft engaging unit. The lock core is rotatable in the lock shell between locking position and unlocking positions. The limiting unit limits rotation of the lock core in the lock shell. The key is inserted removably into the key compartment and is operable so as to drive rotation of the lock core between the locking and unlocking positions.
