Abstract

The invention relates to a closed lock with a brand new structure. The closed lock comprises a lock case, a lock plug, a lock cylinder and a key. The lock plug and the lock cylinder are respectively installed on the left side and the right side of the lock case. The lock plug consists of a lock pillar and a supporting rod. The lock cylinder consists of a stop block, an isolating block, a core plate, a base and two groups of pins. The closed lock has the advantages that the design is ingenious, the structure is reasonable, reliable and durable, the closed lock is simple to operate, the safety level is high, the lock belongs to a long-time anti-opening lock, the lock can enable technical unlocking to be failed genuinely as the lock is in a full-closed state during unlocking and the lock is not in contact with the external world, and the lock is really prying-resistant and violence-resistant. Moreover, any key can be duplicated and may be lost even though the key is complex. However, the key which is provided by the invention is required to be additionally set on the site during unlocking, equivalently a code function is obtained and the problem that the key is duplicated and lost can be prevented.

[0001] The invention relates to a lock, in particular to a closed lock. Background technique

[0002] At present, the mechanical management lock cylinder has a structure of upper and lower pins, and the supplementary beads are managed in layers, so that the thief can first apply a rotational force to the lock cylinder when performing technical opening, so that the flat beads are pressed to the side, and then they can be used again. The precision error of machining opens the marbles one by one. When all the marbles are on the same plane, the lock cylinder can be opened, thus opening the whole lock for theft. As can be seen from the above, the current mechanical management lock is only convenient to use, but cannot prevent technical opening, and its anti-theft performance is extremely low.

[0003] There is also a complex internal lock cylinder, which is also the main method of unlocking with existing anti-techniques. The complex internal core makes the unlock...
