Each pair of lock cylinders corresponds to four combination conditions, the number of the arrangement and combination conditions is the power of N of 4, and N is the number of the lock cylinder pairs; in order to ensure the safety of the lock, the minimum number of the lock cylinders is 4, and 256 kinds of arrangement and combination conditions exist; the recommended number is 6 pairs, 4096 permutation combinations are provided, which not only ensures low cost, but also ensures safety.

The lock cylinder of the utility model has two types, namely a large lock cylinder and a small lock cylinder; the small lock cylinder is a normally closed lock cylinder, a key is not inserted into the small lock cylinder, the small lock cylinder is closed (a small cylinder of the small lock cylinder is inserted into the through hole A and the through hole B), and the key is inserted into the small lock cylinder to be unlocked (the small cylinder of the small lock cylinder is separated from the through hole A and the through hole B); the large lock cylinder is a normally open lock cylinder, and is unlocked when a key is not inserted, and the key is also unlocked when the key is inserted (the bars of the large lock cylinder are not inserted into the through hole A and the through hole B), and if unqualified keys are inserted, the lock catch is locked in a closed mode, so that unlocking is prevented (the bars of the large lock cylinder are inserted into the through hole A and the through hole B); the two kinds of lock cylinders are randomly arranged. The magnet of the small lock cylinder is arranged at one end of the column body with a large diameter, and the magnet of the large lock cylinder is arranged at one end of the core body 402 far away from the connecting frame 401; the key needs to attract the magnet of the small lock cylinder and repel the magnet of the large lock cylinder.

In the utility model, the magnetic poles in the direction corresponding to the key hole of each lock core are the same (hereinafter, the magnetic poles are uniformly set as N poles), the upper row and the lower row repel each other, the spring is saved while the safety is realized, and the cost is saved. The following are four permutation and combination conditions of each pair of lock cylinders:

1) the corresponding position of the key needs the magnet with the magnetic pole direction of an upper N pole and a lower S pole to correspond to each other;

2) the corresponding position of the key needs the magnets with the magnetic pole directions of an upper S pole and a lower N pole to correspond to each other;

3) the key can not interfere with any one of the upper lock cylinder and the lower lock cylinder, and nonmagnetic substances are used in corresponding positions;

4) the upper small lock cylinder and the lower small lock cylinder are connected with the key through the connecting rod, and the key is required to attract the upper N pole and the lower N pole simultaneously, so that the magnet cannot be used and the iron is required to correspond to the key.

The working principle of the utility model is as follows: when the key is inserted into three quarters of the lock cylinder from the key hole, the through groove for placing the material on the key corresponds to the position of the concave hole on the lock cylinder frame, and the lock cylinder is unlocked under the interaction of the four conditions listed above; after the key is completely inserted, the key can push the lock catch, and the clip-shaped retaining ring of the lock catch is separated from the locking groove of the locking ring, so that the locking ring is unlocked; the lock ring is bounced off by the elasticity of the spring to be successfully unlocked; the locking ring may rotate 360 deg.. When the lock ring is pressed back to the original position, the lock catch can be rebounded by another spring (at the moment, the key is pulled out), and the lock ring is locked again, so that the locking is realized.

The utility model provides a new unlocking mode, which is not only suitable for padlocks, but also can be added into an embedded anti-theft lock of an anti-theft door, and the lock core can be disassembled and replaced to be arranged and combined for replacing keys, so that the lock is not replaced by replacing keys, the unlocking mode is suitable for rented rooms or second-hand rooms considering hand changing, and the replacement cost brought by the time of replacing keys when the houses are rented, sold, lost or stolen and the like can be effectively reduced.
