The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.

See Fig. 1 and Fig. 2, turntable coded lock core provided by the invention mainly comprises rotating shaft 0 and several rotating disks 1,2,3,4.But the number of rotating disk is not limited to this, corresponding number can be set as required.

Rotating shaft 0 is the power set of whole turntable coded lock core.

Rotating disk 1,2,3,4 is critical components that turntable coded lock core password is formed, and these rotating disks are in the same size, and are all set in rotating shaft 0, thus forms coaxial turntable.

Meanwhile, rotating disk 1,2,3,4 radially direction is provided with corresponding draw-in groove 14,13,12,11, and when the draw-in groove on all rotating disks is all positioned at enable possition, coded lock is opened.

Open to realize available automated tool, the present invention, by affixed with rotating shaft 0 for the rotating disk 1 (equally also can adopt another rotating disk 4 being positioned at outside) being positioned at outside, with axis of rotation, can become driving disc spacing pressing; All the other rotating disks 2,3,4 are as clutch plate simultaneously, and movable is set in rotating shaft 0, and can both rotate around the axis under the drive of driving disc spacing pressing.

In order to realize driving all clutch plates and can password be arranged, the card that the present invention is relative between all rotating disks is all provided with plectrum 5,6,7,8,9,10, the card that its turntable 1 is relative with rotating disk 2 arranges plectrum 5, the card that rotating disk 2 is corresponding is provided with plectrum 6, and plectrum 6 is corresponding with plectrum 5 in the position along rotating disk radial direction, rotating disk 1 makes plectrum 5 can interference with plectrum 6 with the spacing between rotating disk 2 simultaneously, namely when plectrum 5 rotates with rotating disk 1 and through plectrum 6 position, plectrum 6 can be promoted, thus drive rotating disk 2 to rotate.

Based on above-mentioned principle, the card that rotating disk 2 is relative with rotating disk 3 arranges plectrum 7, the card that rotating disk 3 is corresponding is provided with plectrum 8.

The card that rotating disk 3 is relative with rotating disk 4 arranges plectrum 9, the card that rotating disk 4 is corresponding is provided with plectrum 10.

Plectrum positional symmetry in two cards of simultaneously each rotating disk, and angle folded by plectrum, draw-in groove and circle center line connecting is a, 360 degree of > a > 0 degree.

Rotation due to rotating disk is all mutually interfered by the plectrum between rotating disk and is driven, so the relative position on rotating disk between plectrum forms the password of this turntable coded lock core.

As the prioritization scheme of such scheme, the present invention is arranged in rotating shaft by the even distance of rotating disk 1,2,3,4, and simultaneously all plectrums 5,6,7,8,9,10 adopt identical structure, and its height, width are all identical.

Thus, the password number P of turntable coded lock core is as follows:

$P={\left(\frac{2\mathrm{\ΩR}}{D}\right)}^N$

Wherein R is the radius of rotating disk, and D is the thickness of plectrum, and N is the number of rotating disk.

Based on the lock core that such scheme obtains, its carrying out practically principle is as follows:

Whole turntable coded lock core is made up of the multiple coaxial turntables be enclosed within same rotating shaft, between each rotating disk, the position of diametrically answering is provided with plectrum, and these plectrums interfere with each other, and drives rotating disk to rotate around the axis, and forms password by the relative position between plectrum.

See Fig. 2, rotating shaft drives rotating disk 1 to rotate clockwise, and the plectrum 5 on it rotates with rotating disk 1, when rotating disk 1 turn to plectrum 5 can interfere the position of plectrum 6 time, plectrum 6 (under stirring) under the interference of plectrum 5 rotates with it, and now drive rotating disk 2 rotates clockwise by plectrum 6;

When the plectrum plectrum 7 that rotating disk 2 turns on it can interfere the position of plectrum 8, plectrum 8 (under stirring) under the interference of plectrum 7 rotates with it, and now drive rotating disk 3 rotates clockwise by plectrum 8;

When the plectrum 9 that rotating disk 3 turns on it can interfere the position of plectrum 10, plectrum 10 (under stirring) under the interference of plectrum 9 rotates with it, now drive rotating disk 4 rotates clockwise by plectrum 10, until the draw-in groove 11 on it is turned to enable possition.

Now start to rotate counterclockwise rotating disk 1, plectrum 5 stirs plectrum 6 again, thus drives rotating disk 2 to rotate counterclockwise, and the plectrum 7 on it stirs plectrum 8, then drives rotating disk 3 to rotate counterclockwise, until the draw-in groove 12 on it turns to enable possition.Now because rotating disk 3 rotational angle is less than 360 °, so the plectrum 9 on rotating disk 3 can not interfere with the plectrum 10 on rotating disk 4, rotating disk 4 can not be driven, and draw-in groove 11 is still in enable possition.

In like manner continue to rotate clockwise rotating disk 1, plectrum 5 stirs plectrum 6 again, and drive rotating disk 2 to rotate clockwise, the draw-in groove 13 on rotating disk 2 is turned to enable possition, and now draw-in groove 11,12 is still in enable possition.

Continue to rotate counterclockwise rotating disk 1, the draw-in groove 14 on it is turned to correct position, now draw-in groove 11,12,13 is still in enable possition, and now each draw-in groove all drops on enable possition.
