Abstract: A burglarproof lock core assembly has a lock shell, a lock core and a pin device. The lock shell has a mounting recess, multiple upper pin chambers and an engaging slot. The lock core is mounted in the mounting recess and has a keyhole, multiple lower pin chambers, multiple sliding channels, multiple sliding rods, a tab recess and an engaging tab. The sliding channels are formed through the lock core near the lower pin chambers. The sliding rods are mounted in the sliding channels, and each has a releasing recess, a burglar-misleading recess and at least one guiding post. The tab recess communicates with the sliding channels and selectively faces the engaging slot. The engaging tab is mounted between the engaging slot and the tab recess. The pin device is mounted between the lock shell and the lock core and has multiple pin sets mounted in the pin chambers.

Abstract: A lock core assembly has a lock shell, a lock core and a pin segment. The lock shell has multiple upper pin chambers and a lid. The lock core is mounted rotatably in the lock shell and has multiple lower pin chambers. The lower pin chambers are formed radially through an outer surface of the lock core and respectively align 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 including at least one suspended pin assembly. Each suspended pin assembly has a suspending spring and a suspending block. The suspending spring is connected to a lower pin. The suspending block is mounted on and supported by the suspending spring and abuts with a returning spring.

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, a lid and at least one retaining flange. 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 abutting pin assemblies and at least one suspended pin assembly. When knocked, a suspended upper pin of the at least one suspended pin assembly prevents the pin aligning and the lock core from rotating, the lock core assembly provides a preferred burglarproofing effect.

Abstract: A lock core assembly has a lock shell, a lock core, multiple pin assemblies and at least one anti-knock pin assembly. Each pin assembly is mounted in a mounting chamber formed radially in the lock shell and through the lock core. Each anti-knock pin assembly has an upper pin and a major spring abutting each other and is mounted in a corresponding characteristic chamber assembly with a core chamber and at least one limiting recess communicating with each other. When a burglar turns the lock core by using a lock pick to vibrate or knock the lock core, the major spring presses the upper pin to engage in the limiting recess to limit the lock core and provide a reliable and reusable burglarproof lock that need not be replaced after an attempted malicious opening.

Abstract: A lock core assembly has a lock shell, a lock core mounted rotatably in the lock shell, multiple pin assemblies and an arrestor. Multiple mounting chambers are formed between the lock core and the lock shell. The pin assemblies are mounted respectively in the mounting chambers and each have an upper pin situated at an interface between the lock core and the lock shell to prevent a rotation of the lock core and a lower pin with an annular groove. The lock shell has a retaining cavity formed inside. The lock core has a mounting recess communicating with the mounting chambers and aligning with the retaining cavity. The arrestor is mounted slidably in the mounting recess. Without inserting a right key into the lock core, the arrestor is held in the retaining cavity to prevent the lock core from rotating to provide an improved burglarproof effect.

Abstract: A lock assembly with an improved burglarproof lock core has a casing, a lock core and multiple outer chambers. The casing is mounted in a lock device and has a core hole and multiple outer chambers. The lock core is mounted in the core hole and has multiple inner chambers and a keyhole. The inner chambers correspond to the outer chambers in the casing. Each locking pin assembly is mounted slidably in the corresponding outer and inner chambers and has an inner and outer locking. The inner locking pins are flush with the inner chamber when the lock device is unlocked, and at least one inner locking pin is magnetic. The outer locking pin corresponding to the magnetic locking pin is held to ensure that the lock assembly won't be unlocked when someone attempts to tap the locking pin assemblies to pick the lock device.

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.
