tartar

12,13; Be respectively equipped with

tartar

14,15 on sub-key 11 orthogonal sides and the top, conversion key 10 top tartars 13 and corresponding side tartar 12 parts are identical, the length of lock pearl 9 in dark one of another part.Sub-key 11 top tartars 15 and corresponding side tartar 14 parts are identical, the length of lock pearl 9 in dark one of another part.The tartar 12 that said conversion key 10 two sides are provided with is single tartar, be provided with because the tartar of sub-key 11 two sides in the present embodiment is eccentric, so the tartar 13 that sub-key 11 two sides are provided with is double tartar.

Described conversion key 10 is a set of keys with sub-key 11.

Shown in Fig. 1, Fig. 2, this lock core contains parts such as key, lock core, lock shell, lock valve jacket, because the middle lock pearl in the present embodiment has six; Therefore have 8 kinds of modes of unblanking; So the key in the present embodiment is divided into eight groups (ABCDEFGH), every group of two keys are used key for conversion for one in every group of key; Another uses key for the user, and key tooth flower is all inequality between each group.

Wherein the quantity of set of keys can be based on quantity and the customer requirement preparation of middle lock pearl.

Lock shell 3 has three row's concentric lock hole of

beads

31,32,33; All put into the pearl 8 of locking, lock pearl spring 7 in the lock shell lock hole of

bead

31,32 successively; All put into lock pearl 9, the pearl 8 of locking, lock pearl spring 7 in the lock shell lock hole of bead 33 successively, all push up on the inwall that is against lock valve jacket 4 above-mentioned lock pearl spring 7 upper ends.It is concentric and can lock the lock hole of

bead

21,22 that the hole of bead coincides with corresponding lock shell when rotating with the lock shell that lock core 2 is provided with two rows; All put into down lock pearl 6 in the lock core lock hole of

bead

21,22, wherein lock pearl 6 is the following lock pearl that several and conversion

key tooth flower

12,13 and

sub-key tooth flower

14,15 are complementary down.The pearl 8 of wherein locking moves up and down in lock shell 3, and middle lock pearl 9 moves up and down in lock shell 3 and lock core 2, and following lock pearl 6 moves in lock core 2.

During assembling; Put into the following lock pearl 6 that is complementary with on the key tartar in lock core on the lock core 2 lock hole of

bead

21,22 respectively; A left side turn 90 degrees the lock shell 3 of packing into and makes the lock core lock hole of bead 21 lock the hole of bead 32 with the lock shell to align then; Align with the lock shell lock hole of bead 33 in the lock core lock hole of bead 22, lock then and put into lock pearl 8 and lock pearl spring 7 in the shell lock hole of

bead

31,32 successively, and put into lock pearl 9 successively in the lock shell lock hole of bead 33, the pearl 8 and lock pearl spring 7 is inserted in lock valve jacket 4 again and overcoat 5 is fixing with regard to completion of locking.

When conversion key 10 inserts lockhole; Conversion key side tartar 12 these rows are complementary with the lock pearl that the corresponding lock core lock hole of bead 21 and lock shell are locked in the hole of bead 32; Just become to unblank shape, be complementary and conversion key top tartar 13 is locked the hole of bead 2 with corresponding lock core and lock the shell lock hole of bead 33 internal lock pearls.Because lock pearl 9 in all being placed with in the lock shell lock hole of bead 33; On lock pearl corresponding to conversion key top tartar 13 dark toothed portions; Its lock pearl spring 7 effects are pressed into middle lock pearl 9 in the lock core lock hole of bead 22 fully; Make down lock pearl 6 and middle lock pearl 9 length and conversion key top tartar 13 dark toothed portions couplings altogether, and the pearl 8 of locking this moment also is positioned at the lock shell lock hole of bead 33, the interface place that the intersection of top of middle lock pearl 9 and the lower surface of the pearl of locking just is in lock core 2 and locks shell 3.And corresponding to the lock pearl of conversion key top tartar 13 shallow toothed portions; Wherein lock pearl 9, the pearl 8 of locking supported to locking in the shell lock hole of bead 33 by the top; And lock pearl 6 is positioned at the lock core lock hole of bead 22 down; The intersection on the top of lower surface of lock pearl 9 and following lock pearl 6 just is in the intersection between lock core 2 and the lock shell 3 in this moment, therefore at this moment can rotate each other between lock core 2 and the lock shell 3.Insert conversion key 10; Key 90 degree of turning right again make lock be normal operating condition; Brought to the lock shell lock hole of bead 32 in corresponding to the middle lock pearl 9 in the lock shell lock hole of bead 33 of conversion key top tartar 13 dark toothed portions this moment; Extract the conversion key then, this moment, this lock can only just can be unblanked with this conversion key 10 or the sub-key 11 identical with its tartar.If need change the key of other groups the time, only need these conversion key 10 insertion left sides to turn 90 degrees [what is called makes zero] later on, will prepare the conversion key insertion right side that to change again and turn 90 degrees and get final product.

When using for the first time A group key, all the other seven groups (BCDEFGH) all can not open this lock core.

As to change B group key into when using key; The key of insertion A group conversion earlier turn 90 degrees counterclockwise to be extracted; A group conversion this moment key can be brought the middle lock pearl that part and key tooth flower own are complementary in the lock hole of bead of lock shell-side face into; Insert conversion key or other any one group of conversion key of B group again, turn 90 degrees clockwise again, the key original place of playbacking.Wherein the B key can be taken away the middle lock pearl that a part wherein is complementary with key tooth flower own, and still is retained in the lock hole of bead of locking on the shell 3 with middle lock pearl that the A key tooth flower is complementary.At this moment, change the key success, can only use the B key unlocking now, and all the other (ACDEFGH group) keys can not be unblanked.

Embodiment 2

As shown in Figure 3, the structure of lock shell 3 ', lock core 2 ' and conversion key 10 ' only is a kind of distortion of embodiment 1 in the present embodiment, and in addition, other structure is identical with the structure of implementing in 1 in this structure.Lock shell 3 ' is provided with two row's lock shell lock hole of beads 31 ', 32 ' in the present embodiment 2, has only the row's lock core lock hole of bead 21 ' that is complementary with it on the lock core 2 '.The pearl 8 ' of locking moves up and down in lock shell 3 ', and middle lock pearl 9 ' is motion respectively in lock shell 3 ' and lock core 2 ', and following lock pearl 6 ' moves in lock core 2 '.

Like three key A, B, the C with different tartars, when the A key was initial key, an insertion A left side turn 90 degrees extracted, and the B in inserting other two keys just can change, and changes back A key and no longer can use, and B can use; In like manner, replaceable is the C key.

Above-described embodiment is the more preferably specific embodiment of the invention, and common variation that those skilled in the art carries out in the invention technical scheme scope and replacement all should be included in the protection domain of the invention.
