The specific embodiment

For the clearer the technical solution of the utility model that intactly discloses, below in conjunction with drawings and Examples, specifically introduce the utility model.

Magnetic cipher lock provided by the utility model is coordinating with the key of magnetic conductivity object and lock body with permanent magnet, both have special magnetic texure, both are at the specific magnetic characteristic of the interior generation of certain distance, can be used as password with this magnetic characteristic and control and unblank or locking.Following paper is the structure of key once:

One, key

Key is comprised of key body 11, rectangular recess 12 and password body 13.

Key body 11 is to be made by non-magnet material, usually uses copper (though aluminium is typical non-magnet material, still because of the softer and uncomfortable key that is fit to do of its quality).Key body 11 has conventional key profile, comprises handheld terminal and insertion end.Insertion end at key body 11 is provided with several rectangular recess 12, and is embedded in by several password body 13 that object in key forms, as shown in Figure 1.Rectangular recess 12 is used for holding the standard machinery pellet.Form in several objects of password body 13, several are arranged is magnetic conductivity objects 14, and such as iron wire or iron prop, all the other are that non-magnetic object 15(is as copper wire or copper post).

The quantity of password body 13 is no less than 1, when only being 1, can only be the magnetic conductivity object.The minimum number of rectangular recess 12 can be 0, and when the quantity of rectangular recess 12 is 0, this lockset is exactly pure magnetic cipher lock, as shown in Figure 2.

As special case, the magnetic conductivity object in password body 13 can be cylinder, can be also cone, can be also the polygon cylinder, in a word various shape can be arranged.Non-magnetic object in password body 13 also can have various shape, can be cylinder, can be also cone, can be also the polygon cylinder, can be also integral production with key, specifically depending on working (machining) efficiency.

As special case, rectangular recess 12 can be designed one by one little groove (as shown in Figure 1), interts with password body 13 and puts; Also can be designed large elongated slot in a row (as shown in Figure 3), put with password body 13 apportions, password body 13 also is arranged in a row.

The degree of depth of rectangular recess 12 can be also deep mixed, and the structure that this depth is different forms mechanical cipher, or claims spring concealed puzzle.

Above-mentioned said password body 13 is embedded in key, and this embedding can be that penetrability embeds; Can be also that superficiality embeds, that is to say the visible groove in front and the password body (cannot see the password body after plating) of key, reverse side be smooth.And the password body is concordant with surfaces of keys.

Rectangular recess 12 in above-described embodiment, can be also circle, ellipse, square, rectangle, Long Circle in principle, but the most suitable with rectangle, Long Circle, and now key insertion is extracted more smooth and easy.

Below introduce again and the matching used lock body structure of key:

Two, lock body

Except key, all mechanisms all are arranged on lock body directly or indirectly, especially are used for installing lock core.As shown in Figure 4, lock body comprises a lock body 21, on lock body 21, an electric lock core 22 is installed, and also a machine lock core 23 can be installed simultaneously.Electric lock core 22 all is connected with shifting block 24 by clutch with machine lock core 23, can insert electron key from a side and stir shifting block and unblanked, and also can insert mechanical key from opposite side and stir shifting block and unblanked.Electric lock core 22 is exactly matching used with above-mentioned magnetic pin key.When lock only has electric lock core 22, electric lock core 22 also can be fixedly connected with shifting block 24, drives shifting block by the electric lock core and rotates.

A side surface (or on together with lock body) at electric lock core 22, offer several marble holes 25, leads directly to the key to lock core, in marble hole 25, pellet 26 and spring 27 are housed, and pellet 26 and spring 27 are packed in periphery, and pellet 26 inwardly is against on key.The quantity of marble hole 25 and position location are corresponding with quantity, the position location of rectangular recess 12 on the key, only have quantity and position correspondence, when key inserts, pellet 26 just can be squeezed into marble hole 25 tops, pellet 26 in marble hole 25 just can be against in rectangular recess 12 under spring action, and being tight against those in rectangular recess is pellets different in size, on the surface of lock core, just can be presented as concordantly, key also can be stirred lock core and rotate.For not having reeded key, do not relate to coincideing of pellet and groove, at this moment key injects key just rotatably.

Also offer a plurality of blind holes 28 on a side surface of electric lock core 22, blind hole 28 is corresponding with password body 13 positions, the quantity of key, and permanent magnetism pearl 29 is installed in blind hole.After the key with magnetic conductor inserts the electric lock core, magnetic conductivity object 14 is by 29 magnetization of permanent magnetism pearl, and the key with password body 13 forms a magnetic pin key thus, can be detected by Magnetic Sensor.

Through presetting, when the testing circuit 30 with Magnetic Sensor, while detecting the test signal of magnetic pin key, be transferred to treatment system (single-chip microcomputer), system is combined into a test patterns to these detection signals, with predefined password in system, compares, while matching, signal to control circuit, by control circuit, control the 31(of executing agency as electromagnet mechanism) allow key to continue to stir the lock core rotation, just can be unblanked; If password is misfitted, control circuit will be controlled executing agency's restriction lock core and be rotated further, and can not unblank.

The magnetic conductivity object (as iron wire) and the non-magnetic object (as copper wire) that embed on the key form a password, after key inserts key, magnetic conductor is magnetized, export a kind of signal with the Magnetic Sensor of its relevant position, after key exits key, magnetic conductor loses magnetism immediately, therefore key will no longer have magnetic, and random storing keys, do not worry magnetic conduction or magnetic destruction problem.
