Quick-Change Lock Assembly With Anti-Loosening Bolt Structure

The locking device is segmented into modular components: a reusable lock body remaining on the door, and interchangeable lock-changing assemblies that can be quickly removed and replaced. This segmentation allows only the necessary portion (lock-changing assembly) to be changed rather than the entire lock system, significantly reducing lock changing time while maintaining security through the persistent lock body.

The lock body is designed as a universal base that can accommodate multiple different lock-changing assemblies through a standardized interface. This multi-functionality allows a single lock body to support various key types and locking mechanisms, enabling quick replacement of lock-changing assemblies without replacing the entire lock system, thus reducing time loss while maintaining reliability.

By segmenting the lock system into a permanent lock body and replaceable lock-changing assemblies, the invention simplifies the replacement process. Only the compromised lock-changing assembly needs to be removed and replaced, rather than disassembling and replacing the entire lock mechanism. This reduces both the complexity of the replacement process and the associated costs while maintaining security through the intact lock body.

The lock-changing assemblies are pre-configured with different key mechanisms and can be quickly snap-fit onto the lock body. This preliminary preparation of standardized interfaces and pre-assembled units eliminates the need for complex on-site assembly procedures, reducing replacement complexity while ensuring security through properly configured locking mechanisms.
