Mechanically keyed locks with isolated validation

PCT designated stageWO2026085527A3Cylinder locksSoftware engineeringRelative motion
A lock assembly including a locking module assembly extending along an actuation axis. The locking module assembly includes a carrier assembly configured to rotate and translate along the actuation axis, a spacer assembly rotationally coupled to the carrier assembly, a validation bar movable with the carrier assembly, a key engaging assembly with key engaging elements, and a key validating assembly with corresponding key validating elements. A housing defines a cylindrical cavity to receive the locking module assembly and includes a clearance slot for the validation bar. A displacement mechanism induces relative movement between the carrier assembly and housing, causing separation of the key validating assembly from the key engaging assembly during operation. The lock assembly enables secure key validation and offers potential for rekeying functionality.

Anti-theft security lock

ActiveCN224314738UCylinder locksStructural engineeringMechanical engineering
This utility model discloses an anti-theft security lock, including a lock shell, a lock cylinder, a lock rod, and a locking block. The lock cylinder and lock shell together form a keyhole. The lock cylinder has a lock cylinder hole, and the keyhole is located on one axial side of the lock cylinder hole and communicates with it. The lock rod can move along the lock cylinder hole to the unlocked position. The lock rod has a slot. When the lock rod moves to the unlocked position, the locking block can move into the slot, allowing the lock cylinder to rotate relative to the lock shell. When the lock rod moves away from the unlocked position, the locking block moves away from the slot and abuts against the lock rod, restricting the rotation of the lock cylinder relative to the lock shell. This utility model, by configuring the keyhole on one axial side of the lock cylinder hole, allows the lock rod to move to the unlocked position by abutting against the paired key when the paired key is inserted into the keyhole, enabling the locking block to move into the slot and unlock the lock. It has the advantages of simplified lock rod structure, compact and reasonable internal lock structure, and simple assembly. Furthermore, because the lock rod moves to the unlocked position by abutting against the paired key, it has the advantages of stable and precise movement.

A theftproof security lock cylinder

PendingCN122169674ACylinder locksClassical mechanicsSpring force
This invention discloses an anti-theft security lock cylinder, including a lock cylinder with an anti-theft mechanism inside. The anti-theft mechanism is used to improve the anti-theft performance of the lock. When unlocking, when the correct key is inserted, after the key has gone a certain distance, the key teeth will push the upper pin 1 to the correct height. At this time, the annular notch groove of the upper pin 1 is aligned with the locking block. Due to the pressure of the spring force, the locking block will be forced to move into the annular notch groove of the upper pin 1 and embed into the notch groove, thereby linking one side of the locking block and causing the locking block to disengage from the annular locking groove of the upper pin 2. This allows the lower pin of the lock teeth to move up and down. At this time, the key will go a certain distance into the lock cylinder, and the frontmost locking tooth of the key will push the lower pin of the lock teeth to the accurate height. At this time, the upper pin 2 will no longer block the lock cylinder and the lock cylinder. The lock cylinder can then be turned by the key, thereby outputting the unlocking action through the bolt.
