As the key enters the keyhole and displaces the push pins and the alignment pins, the engagement holes in each alignment pin are individually aligned with the longitudinal slits in the lock core to disengage the engagement strips in the longitudinal slit. It allows insertion into aligned engagement holes, so that the lock core can be rotated in the cylinder to unlock the lock.

Locks are widely used in locations and places where it is necessary to monitor, restrain and restrict access to objects. Locks are very important for protection and surveillance. Thus, people have many opportunities to use locks in their lives, and locks have always occupied their important positions.

The most necessary structure for a lock is a lock core, cylinder, locking beards, locking pins or bolts. The most widely used locks today have adjacent locking pins, which are upright. In the case of a lock of that kind, there must be a wider space for accommodating the locking pins, and the cylinder has a square portion that protrudes to accommodate the locking pins. They make production very cumbersome and make it very difficult for locksmiths to mount locks. Friction may occur as a result of the contact between the locking pins, and the locking pins may wear out, unlocking the lock and increasing the inconvenience in locking.

Furthermore, very large portions of the lock pins are exposed to the keyhole of the lock core, and a key inserted into the key hole may collide with the lock pins, causing the lock pins to break off or tilt, indirectly damaging the lock. This can also adversely affect unlocking and locking.

And then the engagement strip is inserted into the plurality of aligned engagement holes of the alignment pins, allowing the lock core to rotate in the cylinder to release the lock.

A secondary object of the present invention is to ensure that the movement of the push pins and the alignment pins is limited by the receiving and alignment holes provided in the lock core so that the push pins and the alignment pins are not accurately positioned and biased.

A third object of the invention is that the positions of the engagement holes in the alignment pins are mismatched so that the alignment holes can only be aligned after they have all been moved to the correct position which allows the engagement strip to enter into the alignment holes. Therefore, it is to effectively prevent excessive damage by external force.

A fourth object of the present invention is to secure the structure of these pins by allowing the push pins and the alignment pins to be connected in parallel in an adjacent relationship within the lock core.

A fifth object of the present invention is to allow the push pins and the alignment pins to be integrally combined with each other or to be connected to the connecting plate so that a plane is formed between the push pins and the alignment pins.

A sixth object of the present invention is to allow each alignment pin in the form of a straight board to be connected in parallel with the push pin in an adjacent relationship.

The seventh object of the present invention is to install all the pins and the alignment strip in the lock core so that no additional space is required in the cylinder of the lock to accommodate the pins.

An eighth object of the present invention is to bring the engaging ends of the engaging strips in the form of a straight board into direct engagement with the grooves provided in the cylinder, so as to improve the engagement effect.

A ninth object of the present invention is to provide rod-shaped push pins installed transversely on top of the alignment pins so that the rod-shaped push pins protrude into the guiding way of the key, and the guide surface thereof. By sliding and displacing the alignment pins into their proper positions, the alignment holes in the alignment pins align with the longitudinal slits in the lock core, thereby allowing the engagement strip to engage the engagement holes so that the lock core can rotate in the cylinder. have.
