Description

Technical Field

[0001] The utility model relates to the technical field of lock cores, in particular to a half-moon structure of a lock core for a door lock. Background Art

[0002] The lock core uses multiple anti-theft technologies and a variety of special-shaped anti-pulling pins to prevent technical opening. With the unique pin and blade structure design, it has a high security performance against technical opening. The lock core is equipped with precision number pins and special-shaped pin structures. When technical opening is performed, the number pins and special-shaped pins must be pulled out at the same time, and the lock will be automatically locked, making the technical opening ineffective. The lock core uses a variety of special-shaped pins with multiple combinations, and can compile up to billions of key numbers, thereby achieving zero mutual opening in the area (one in 16 million). The lock core has added a lateral inward pressure side column latch device, which greatly improves the ability to prevent violent twisting.
