It changes the method for operating of key about the core 1 of this replaceable key, see also shown in Figure 4, it is to comprise the core of replaceable key step 500 is provided, one key is inserted lock benevolence body step 510, the rotation key is to drive lock benevolence body and locating piece rotation step 520, plug the instrument pushing and pressing face of hole with changing the instrument that the key instrument inserts perforate and locating piece, and the first tooth position part is moved and remove engagement step 530 with the second tooth position part with the pushing tow locating piece, extract key step 540 out, new key is inserted lock benevolence body step 550, extract out and change the key instrument so that the first tooth position part and the second tooth position part mesh step 560 again and rotate new key so that core recovers steps such as normal operating condition 570.
By the core 1 of this above-mentioned replaceable key, only reach and to unblank and can't carry out key and change being described as follows of purpose with the correct key of coupling.
At first, see also Fig. 1, Fig. 3 and shown in Figure 4, in the core step 500 of a replaceable key is provided, it is with this lock housing 10, this lock benevolence group 20, those lock pearl 30 and 40 combinations of those adjustment parts, with the core 1 of forming this replaceable key, in the present embodiment, it is to should locking this perforate 212 of benevolence body 21 that this instrument of this locating piece 23 plugs hole 232, and those first tooth position parts 221 are to be engagement with those second tooth position parts 222; Afterwards, see also Fig. 4 and shown in Figure 5, in a key being inserted lock benevolence body step 510, it is this key hole 213 that a correct key 60 is inserted this lock benevolence body 21, and this correct key 60 is to move on meeting those assembling lock pearls 22 of pushing tow and those adjustment parts 40, in the present embodiment, after this correct key 60 inserts this key hole 213 of this lock benevolence body 21, those adjustment parts 40 are respectively these lock hole of beads 211 that are arranged in this lock benevolence body 21, this correct key 60 only with those adjustment part 40 pushing tows to rotating the interface; Then, see also Fig. 4 and shown in Figure 6, rotate in the step 520 to drive lock benevolence body and locating piece at the rotation key, be that this correct key 60 of rotation turns to a predetermined angular position to drive this lock benevolence body 21 and this locating piece 23 in this lock housing 10, and be arranged at respectively this assembling lock pearl 22 in this lock hole of bead 211 respectively and respectively this adjustment part 40 be simultaneously by these lock benevolence body 21 drives, in the present embodiment, respectively this adjustment part 40 is to rotate along this inside wall 10a, see also shown in Figure 6, when this lock benevolence body 21 and this locating piece 23 by these correct key 60 driven rotary to this predetermined angular position, this locating piece 23 is can be to should elastic reset assembly 13, and this locating piece 23 is these movable plates 131 of this elastic reset assembly 13 of meeting conflict, and respectively this first tooth position part 221 is to be restricted between this inside wall 10a of respectively this first cambered surface 40a of this adjustment part 40 respectively and this lock housing 10, respectively respectively this first cambered surface 40a of this adjustment part 40 is respectively respectively this circular arc end face 225a of respectively this pushing part 225 of this first tooth position part 221 of butt, and respectively respectively this second cambered surface 40b of this adjustment part 40 is this inside wall 10a of this lock housing 10 of conflict, so that this instrument of this locating piece 23 plug hole 232 and respectively this first tooth position part 221 respectively be formed with a potential difference A between this contraposition groove 226, and make that changing key instrument (scheming not shown) can't plug hole 232 via this this instrument of locking benevolence body 21 these perforates 212 these locating pieces 23 of insertion, promptly make this replacing key instrument 70 can't push this locating piece 23 and remove the engagement of the first tooth position part 221 and the second tooth position part 222, thereby can't carry out follow-up key and change step 530,540,550,560 and 570, because after this correct key 60 inserts this key hole 213 and rotation of this lock benevolence body 21, those adjustment parts 40 only can cause this instrument to plug hole 232 and respectively produce this potential difference A between this contraposition groove 226, but those adjustment parts 40 can't limit this lock benevolence body 21 and this locating piece 23 rotates in this lock housing 10, therefore this correct key 60 still can be finished unlocking action, but can't change key.
At first, see also Fig. 1, Fig. 3 and shown in Figure 4, in the core step 500 of a replaceable key is provided, it is with this lock housing 10, this lock benevolence group 20, those lock pearl 30 and 40 combinations of those adjustment parts, with the core 1 of forming this replaceable key, in the present embodiment, it is to should locking this perforate 212 of benevolence body 21 that this instrument of this locating piece 23 plugs hole 232, and those first tooth position parts 221 are to be engagement with those second tooth position parts 222; Afterwards, see also Fig. 4 and shown in Figure 7, in a key being inserted lock benevolence body step 510, it is this key hole 213 that a control key 70 is inserted this lock benevolence body 21, and this control key 70 is to move on meeting those assembling lock pearls 22 of pushing tow and those adjustment parts 40, in the present embodiment, insert this key hole 213 of this lock benevolence body 21 when this control key 70 after, those adjustment parts 40 are to be arranged in respectively respectively this storage tank 14 in this hole of bead 11 of locking, and this control key 70 is that respectively these first tooth position part 221 pushing tows with those assembling lock pearls 22 are to rotating the interface; Then, see also Fig. 4 and shown in Figure 8, rotate in the step 520 to drive lock benevolence body and locating piece at the rotation key, be that this control key 70 of rotation turns to a predetermined angular position to drive this lock benevolence body 21 and this locating piece 23 in this lock housing 10, in the present embodiment, those adjustment parts 40 are those storage tanks 14 that can be trapped in this lock housing 10, therefore, after this lock benevolence body 21 and this locating piece 23 turn to this predetermined angular position, this instrument of this locating piece 23 plug hole 232 and respectively this first tooth position part 221 respectively do not have potential difference between this contraposition groove 226, so changing key instrument (scheming not shown) is that this instrument that can insert this locating piece 23 plugs hole 232, thereby can carries out follow-up key and change step 530,540,550,560 and 570.
The present invention allows the core of the replaceable key that mates different keys respectively carry out key with a control key by those adjustment parts 40 change program, and those adjustment parts 40 also can allow this instrument of this locating piece 23 plug hole 232 and respectively this first tooth position part 221 respectively form potential difference between this contraposition groove 226 can't carry out key so that the correct key that the core of this replaceable key mated only can be unblanked and change.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
