ABSTRACT:
A lock core assembly has a lock shell, a lock core and a pin segment. The lock shell has a core mount, multiple upper pin chambers and a lid. The lock core is mounted rotatably in the core mount and has a keyhole and multiple lower pin chambers. The lower pin chambers are formed radially through an outer surface of the lock core, communicate with the keyhole, align longitudinally, correspond to and communicate with the upper pin chambers. The pin segment is mounted between the lock shell and the lock core and has multiple pin assemblies and at least one suspended pin assembly. When knocked, a suspended upper pin of the at least one suspended pin assembly oscillates to prevent the pin aligning and the lock core from rotating, the lock core assembly provides a preferred burglarproofing effect.
