Above-mentioned operation block 16,17,20,18,19 is magnetic or irony operation block, and the key piece matching is can produce with operation block the magnetic or the irony key piece that attract or repel.Above-mentioned operation block is U-shaped, so that density of line of magnetic force increases, improves key operated flexibility.In Fig. 4, key 44 profiles are quad flat bank card shape, have some independent T-shaped posts of arranging on key 44, have the T-shaped groove matching on key piece 49, key piece 49 is arranged on by T-shaped groove on the T-shaped post of key 44, and key piece 49 is magnetic or irony key piece.Key piece carries out the permutation and combination of Corresponding matching according to the operation block in outer lock core, ensured that each key arrangement architecture does not repeat.And can be according to client's needs, adjust controlling screw 39, by client according to the order that need to arrange key piece of oneself.
Embodiment 8
A lock core that comprises one or more technical characterictics in embodiment 1-6, lock pearl groove is arrayed on outer lock core.In Fig. 6, key 44 is made up of two key cards, is all embedded with independent removable key piece in each key card, and key piece carries out the permutation and combination on key card face according to the operation block in outer lock core.Key can be revised as multi-player mode as required, the key that each unlocking person draws oneself up, and the position of the key piece in lock pearl operation block and the key card in outer lock core is set according to personal like, to reach safe and secret object, be applicable to the financial departments such as bank and use.
In the time that lock pearl groove is arrayed on outer lock core, key can be made as to one group by every row or every several row, by the different group of different personnel controls, reach the object of the secret opening lock master of many people.
Lock pearl in lock pearl groove arrangement mode be that two dimensional surface coded system is arranged, in not every lock core groove, have lock pearl.Lock pearl in lock core groove enters after lock pearl groove, also can stuck internal cylinder, discharge internal cylinder after leaving lock pearl groove.Control screw is arranged at special lock core groove bottom, controls the opening and closing of lock pearl.
Key piece in key has three kinds of method settings.The first: little iron block is all arranged at all control points.The second: little magnetic patch is all arranged at all control points.The third: all control points, by little iron block and little magnetic patch mixed-arrangement, have little iron block also to have little magnetic patch in the blockage in key.No matter arrange by that method, the operation block of the key piece in key and lock pearl, all must ensure, every a pair of be all key piece and operation block being oppositely arranged of can attracting each other or repel, thereby play the effect of controlling lock pearl.
Embodiment 9
When initial setting up, control screw and be opening, facilitate user according to the duty that oneself need to change voluntarily lock pearl.Just in case key is lost, maybe will change key time, as long as after taking out standby key and unblanking, from the open/close states of new adjustment control screw, can change the overall alignment structured coding of lock pearl again, after the arranging and encoding of lock pearl changes, originally key is not just opened lock core, thereby guarantees safety.In changing lock pearl work coding, in key, the coding of key piece also will make and change accordingly, is convenient to opening lock master.
Embodiment 10
The present invention, in particular range, also has four kinds of management modes, is now described as follows:
Pattern one, third party's management of key:
1, forward supervision: refer in particular range, with a key, open all lock cores in range of management.A management key is set, the position of the key piece that in management key, in the corresponding range of management in the position of key piece, all lock cores are unblanked.Can realize as office's key management of school dormitory's management or office building, houseparent or office management person can open the lock core of every door in range of management;
2, backward supervision: refer to all keys in cura specialis scope, all can open total lock pin.The key piece position that key piece corresponding lock core in range of management and total lock core are unblanked, the key holder in range of management can be by the office door that the gate of total lock core is housed and mates lock core with key;
3, mixed management: refer to the key within the scope of cura specialis, all can open total lock pin.Total lock key also can be opened other lock core of range of management, but between non-total lock key in range of management, cuts and can not open mutually other lock core.
Pattern two, the trans-regional management of key:
Refer to by the wireless communication mode that waits, the two dimensional surface coding arrangement number of key piece in key is provided to unlocking person by key management people, be convenient to unlocking person restructuring private key coding and unblank again, do not need a key to bring the other side midway.While lock with this, as long as regulate the control screw of lock core groove bottom, can change the lock pearl two dimensional surface coding arrangement number of outer lock core next time again.The arrangement number of change lock pearl two dimensional surface coding, the arrangement of the key of unblanking number also must change, and unlocking person can not be unblanked with original key coding again, so flexible, convenient, safety very.
Pattern three, the separately division management of key:
Refer to that a key makes many parts, for many people's management, only have all key management people, all self-administered part key is provided, and combine, can unblank, indispensable.
Pattern four, key arrange number separate management:
By the two dimensional surface coding arrangement number of the key piece embedding in key, managed by N people, only have all custodians of working as all self-administered coding arrangement number to be provided, can carry out next step the key combined work of unblanking, be also indispensable.
The profile feature explanation of key of the present invention: it is sheet in shape, and volume is thin and light.A lock core private key, can make N kind color and N kind profile, again because private key itself is not with magnetic, so deposit also very convenient, safety.Never repeat feature according to two dimensional surface coding pattern information, the combination of lock pearl will never repeat, and private key also never repeats.
As preferably, the not carrying magnetic of key piece that key is embedded, in lock core, mate with key piece operation block be magnetic patch, key carries the demagnetizations mutually such as bank card that Shi Buhui carries caretaker like this.
