Embodiment

Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.

Incorporated by reference to Fig. 1 and Fig. 2, the present embodiment provides a kind of magnetic coding lock core, including interior body 1, is sheathed on 1 week portion of interior body Ectosome 2 and the shell 3 for being sheathed on 2 weeks portions of ectosome, the ectosome 2 are rotatably assorted with interior body 1, shell 3 and the secure fit of ectosome 2.

Incorporated by reference to Fig. 2, Fig. 3, Fig. 5 and Fig. 6, the middle part of the interior body 1 is provided with the key slot 14 inserted for key；Institute The peripheral part for stating interior body 1 is provided with some grooves 11, and the inner side of the ectosome 2 is provided with and the one-to-one slotted eye of the groove 21；It is provided with the groove 11 and slotted eye 21 of correspondence position for limiting the first position-limit mechanism that ectosome 2 is relatively rotated with interior body 1 Or second position-limit mechanism, in the present embodiment, 16 groups of grooves 11 and slotted eye 21 are provided with altogether, lock core is distributed in up and down Four sides, 4 groups of grooves 11 and slotted eye 21 are uniformly arranged per side.The first magnetic patch that the state of first position-limit mechanism is set in it State is controlled, and the state of state second magnetic patch of setting in it of the second position-limit mechanism is controlled, first magnetic patch and second The state of magnetic patch passes through Magnetic Control by key.

In an embodiment, the key includes being provided with and the groove 11 1 on handle 8 and locking bar 7, the locking bar 7 One corresponding electromagnet 71 is used to control to be provided with control in the state of the first magnetic patch or the state of the second magnetic patch, the handle 8 The circuit board 81 of the magnetic pole direction of the electromagnet 71 and the battery 82 powered for the circuit board 81.

Fig. 2 and Fig. 5 are refer to, first position-limit mechanism includes being arranged at the inner height of groove 11 less than described recessed First magnetic patch 41 of groove depth, is arranged at the inner height of slotted eye 21 equal to the depth of slotted eye 21（It is ectosome 2 in the present embodiment Thickness）The first limited block 42, the outside of first limited block 42 is provided with spring 43 so that the first limited block 42 withstands the One magnetic patch 41.Normal condition or the electromagnet of correspondence position and the first magnetic patch abnormity it is attracting in the case of, the first magnetic patch 41 by The bottom of groove 11 is crushed in the effect of the limited block of spring 43 and first, the first limited block 42 is in the friendship of interior body 1 and ectosome 2 Interface, interior body and ectosome are relatively unrotatable, therefore the magnetism coding key is lockable and can not opened.Only when on the key correspond to position After the electromagnet put is powered, using the principle of same-sex repulsion between magnet, the first limited block 42 is depressed into slotted eye 21 completely, due to The height of first limited block 42 is equal to the depth of slotted eye 21, the interface between the first limited block 42, the first magnetic patch 41 and interior body 1st, the interface between ectosome 2 is overlapped, when interior body 1 and ectosome 2 are relatively rotated, the first magnetic patch 41 and first of the position Limited block 42 does not produce obstruction effect.

Second position-limit mechanism includes being arranged at the second magnetic that the inner height of groove 11 is equal to the depth of groove 11 Block 51, is arranged at the second limited block 52 that the inner height of slotted eye 21 is less than the depth of slotted eye 21, the outside of the second limited block 52 Spring 53 is provided with so that the second limited block 52 withstands the second magnetic patch 51.In normal condition or the electromagnet of correspondence position and second In the case that magnetic patch abnormity is attracting, the second magnetic patch 51 is crushed on the bottom of groove 11 due to the effect of the limited block 52 of spring 53 and second Portion, because the height of the second magnetic patch 51 is exactly equal to the depth of groove 11, the boundary between the second limited block 52, the second magnetic patch 51 Interface between face and interior body 1, ectosome 2 is overlapped, when interior body 1 and ectosome 2 are relatively rotated, the second magnetic patch of the position 51 and second limited block 52 do not produce obstruction effect.When the electromagnet of the second magnetic patch 51 and correspondence position on the key, identical charges repel each other In the case of, the second limited block 52 is depressed into slotted eye 21, and the second magnetic patch 51 is stuck in the interface of interior body 1 and ectosome 2, hinders both Relative rotation, magnetism coding key, which is lockable, to be opened.

Through described above, only when all 16 group of first position-limit mechanism or the second position-limit mechanism are completely in unlocking condition i.e. In the case of not hindering interior body 1, the relative rotation of ectosome 2, the magnetism coding key is just unlocked.And the polarization state of electromagnet For two kinds, 16 groups of position-limit mechanisms just have 2¹⁶Combination is planted, is well imagined, in the case of no correspondence key, the lock base Originally it can not possibly be opened by stranger.

Refer to Fig. 2, the peripheral part of the interior body 1 is provided with the first spacing block set 12, the ectosome 2 be provided with it is described The first stopper slot 22 that first spacing block set 12 is engaged is to limit the rotational angle of interior body.

The peripheral part of the ectosome 2 is provided with the second stopper slot 23, refer to Fig. 7, the shell 3 be internally provided with The second spacing block set 31 that second stopper slot 23 is engaged does not produce relative turn so that shell 3 is relatively fixed with ectosome 2 It is dynamic.

Continue referring on the locking lever sleeve 72 being arranged with Fig. 4, the locking bar 7 positioned at the periphery of electromagnet 71, the locking bar 7 A projection 73 is additionally provided with, refer in Fig. 2, the key slot 14 of the interior body 1 and be provided with the card being engaged with the projection 73 Groove 13 so that locking bar 7 rotate when drive in body 1 rotate, be provided with and match with the key slot 14 and projection 73 on the shell 3 The opening 32 of conjunction is so that key is inserted.

Further, the front end of the locking bar 7 is provided with touching formula switch 74, and the touching formula switch 74 is used to control Battery 82 is powered to circuit board 81, under normal condition, and touching formula switch is not triggered, and key causes normal condition in off-position Lower saving electric energy, when in key insertion key slot 14, touching formula switch 74 touches the bottom of key slot 14, and switch sets out, electricity Pond powers to circuit board.

Fig. 2, Fig. 5 and Fig. 6 are refer to, spring 61 is provided with keyhole and the dust cover of the front end of spring 61 is arranged at 62, in normal state, dust cover 62 is got lodged at the opening of key slot 14 due to the effect of spring 61, prevents dust and other are miscellaneous Thing enters, in use, need to only insert a key into the bottom that dust cover 62 is directly depressed into key slot 14.When extraction key Afterwards, due to the effect of spring 61, dust cover 62 can set back again.

The electromagnet 71 includes iron core and the coil being centered around around iron core.Line with tap centered on its coil Circle, refer to Fig. 8, and centre cap ground connection, coil two ends are all connected on circuit board, and circuit board is responsible for the output of magnetic array.For example, P1.0 exports high level, and P1.1 exports low level, and correspondence coil is to magnetic patch（First magnetic patch or the second magnetic patch）Identical charges repel each other for generation Effect；Then P1.0 exports low level, and during P1.1 output high level, correspondence coil produces the effect that there is a natural attraction between the sexes to magnetic patch.Need It should be noted that the two ends on same coil can not be high level simultaneously or while be low level.

The foregoing is only preferred embodiment of the present utility model, it is all according to present utility model application the scope of the claims done it is equal Deng change and modification, it should all belong to covering scope of the present utility model.
