The course of work of present embodiment 1 is as follows:
When (1), unblanking, as shown in Figure 5, insert key, tartar compression pellet shot from a slingshot 221 indentations of key, the indentation under 232 effects of locking mechanism back-moving spring of locking mechanism 231 the inners this moment goes into to float in the draw-in groove 2411 of pellet shot from a slingshot, like this then the outer end of locking mechanism 231 and the lock slots 11 of lock housing 1 are separated, and then lock core 2 just can rotate in lock housing 1 and unblank;
When (2), locking, as shown in Figure 1, extract key, pellet shot from a slingshot 221 resets under the effect of pellet shot from a slingshot back-moving spring 222, this moment, lock slots 11 directions with the draw-in groove 2411 compressing locking mechanisms 231 past lock housings 1 of the unsteady pellet shot from a slingshot 241 of pellet shot from a slingshot 221 interlocks moved, so lock core 2 and lock housing 1 are locked, reach locking;
(3), when becoming sign indicating number, insert old key, lock is opened, rotational lock core 2, what make lock core 2 as shown in Figure 6 spacingly becomes caulking groove 12 places that sign indicating number groove 25 turns to lock housing 1, this moment, the outer end of spacing change ink recorder structure 251 extend in the caulking groove 12 under spacing change ink recorder structure back-moving spring 252 effects, this moment, spacing change ink recorder structure 251 the inners just no longer compressed set bars 2413, therefore unsteady pellet shot from a slingshot 241 and pellet shot from a slingshot 221 no longer link, extract old key and insert new key and become sign indicating number this moment, as shown in Figure 9, the tartar of new key compression pellet shot from a slingshot 221 makes the change sign indicating number groove 2211 of pellet shot from a slingshot 221 aim at set bar 2413 again, and rotational lock core 2 then, the outer end of spacing change ink recorder structure 251 has broken away from the caulking groove 12 of lock housing 1, spacing then change ink recorder structure 251 is compressed into toward set bar 2413 directions again by lock housing, and the inner of then spacing change ink recorder structure 25 is pressed on the set bar 2413 again, and the pellet shot from a slingshot 241 that will float is integral with pellet shot from a slingshot 221 interlocks, so finished the sign indicating number process that becomes, as shown in figure 10.
Embodiment 2
The specific embodiment of the present invention 2 shown in Figure 10-11, be that with embodiment 1 difference described locking mechanism 231 includes card pearl 2311 and the card 2312 that is linked mutually, the inner of described card 2312 is square, draw-in groove 2411 on the described unsteady pellet shot from a slingshot 241 is the square groove with card 2312 inner scarves, described locking mechanism back-moving spring 232 is arranged at the axial two ends of card 2312, and the direction that resets of this locking mechanism back-moving spring 232 is a radial outward, the outer end of described card 2312 is connected on the inner of card pearl, and the lock slots 11 of described lock housing 1 is and the adaptive deep-slotted chip breaker in card pearl 2311 outer ends.
The course of work of present embodiment 2 is as follows:
When (1), unblanking, insert key, tartar compression pellet shot from a slingshot 221 indentations of key, this moment, card 2312 the inners were aimed at the draw-in groove 2411 of unsteady pellet shot from a slingshot 241, rotational lock core 2, card pearl 2311 is in active force lower compression locking mechanism back-moving spring 232 indentations of lock slots both sides shell wall, and lock housing 1 and card pearl 2311 are separated, and have finished and have unblanked;
When (2), locking, extract key, pellet shot from a slingshot 221 resets under the effect of pellet shot from a slingshot back-moving spring 222, be arranged at the inner of card 2312 and the locking mechanism back-moving spring 232 between the draw-in groove 2411 opens card towards the lock housing direction this moment, finishes locking thereby push card pearl 2311 enters in the lock slots 11 of lock housing 1;
The change sign indicating number process of present embodiment is identical with embodiment 1.
Because present embodiment adopts the locking that is linked of card and card pearl, if during the twisting locked mechanism of lawless person's violence, card will be twisted and warped, tapered end is thoroughly locked at this moment, has improved security of products energy and theftproof performance.
Embodiment 3
The specific embodiment of the invention 3 shown in Figure 12-13, and embodiment 1 difference is: also be provided with between described lock core 2 and the lock housing 1 respectively and lock core 2, the middle lock core 3 that lock housing 1 is rotatably assorted, should connect the side column groove 23 corresponding interlock piece holes 31 that are provided with lock core 2 on the middle lock core 3, described locking mechanism 231 includes fastener 2311 and the interlock piece 311 that radially is linked, and the inside wall of the piece 311 that should link constitutes rotational slips with fastener 2311 and cooperates, this interlock piece 311 is installed in the interlock piece hole 31, and its thickness is greater than middle lock core 3, and the deep equality of the thickness difference of interlock piece 311 and middle lock core 3 and the draw-in groove 2411 of unsteady pellet shot from a slingshot 241, be provided with in the lock slots 11 on the described lock housing 1 and locking mechanism back-moving spring 232 that the piece 311 that links is linked, present embodiment, described locking mechanism back-moving spring 232 and interlock are provided with the ejection piece 132 adaptive with lock slots 11 between the piece 311, the lock core 3 corresponding spacing arranged outside that become sign indicating number groove 25 become sign indicating number pin-and-hole 32 in described, described spacing change ink recorder structure 251 includes the banking stop 2511 of radially interlock and becomes sign indicating number pin 321, and the inside wall that should become sign indicating number pin 321 constitutes rotational slip with banking stop 2511 and cooperates, described change sign indicating number pin 321 is installed on and becomes in the sign indicating number pin-and-hole 32, and its thickness is greater than the thickness of middle lock core 3, the degree of depth fit of thickness difference of the two and caulking groove 12, equating for good, and the degree of depth of this caulking groove 12 should be greater than the degree of depth that becomes sign indicating number groove 2211.
When present embodiment was locked, lock core dallied in middle lock core, as shown in figure 14, had avoided safety problems such as violence unlatching, made the product safety performance be greatly improved.
