Lock assembly with an improved burglarproof lock core

摘要

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.
