[specific embodiment]

A kind of cipher lock, comprise sleeve 1, in sleeve 1, be provided with lock core pole 2, on lock core pole 2, be set with a plurality of password units 3, password unit 3 comprises that the surface is carved with the open circles wheel 31 of numeral, takes turns 31 inboards in open circles and is provided with the alignment pin 311 that aligns with surface number, in open circles wheel 31 spacer 32, the sliding piece 33 that matches with alignment pin 311 is housed successively, be provided with spring 34 in sliding piece 33 1 sides, be provided with baffle plate 35 at the other end of spring 34.

Be provided with a plurality of locating slots 321 that match with alignment pin 311 in the outside of spacer 32, on the interior circle of spacer 32, be provided with the groove 322 that can pass for lock core pole 2 and a plurality of internal diameter width qualification groove 323 less than groove 322; The outside of described sliding piece 33 be provided with a plurality of match with alignment pin 311 stir groove 331, sliding piece 33 centers are provided with the central through hole 332 that passes for lock core pole 2; One side of described lock core pole 2 is arranged with a plurality of grooves 21 that match with spacer 32, sliding piece 33 uniformly, and groove 21 is provided with the qualification step 22 that can match with groove 322, qualification groove 323; Also be provided with a plurality of draw-in grooves 23 on the described lock core pole 2, be fixed with on the draw-in groove 23 and can promote the card 24 that spacer 32 moves; Be provided with the little retaining bolt 26 that can be complementary with groove 322 between described groove 21 and the draw-in groove 23.

Be provided with position plate 11,12 at the two ends of sleeve 1, position plate 11 is provided with can be for the cross-hole 111 of lock core pole 2 insertions, on the position plate 12 of the other end of sleeve 1, be provided with and cross-hole 111 corresponding directional holes 112, one end of described lock core pole 2 is connected in the cross-hole 111, and the other end is connected in the directional hole 112; One end of described lock core pole 2 is fixed with and can promotes the retaining bolt 25 that spacer 32 in the password unit 3 moved and can pass cross-hole 111.

Shown in Fig. 4,8: during installation, spacer 32, sliding piece 33, spring 34 installed successively in open circles wheel 31 and by baffle plate 35 it is blocked, the alignment pin 311 that open circles is taken turns 31 inboards is stuck in the locating slot 321 of spacer 32 and stirring in the groove 331 of sliding piece 33; Be fixed with a plurality of cards on lock core pole 2, the password unit 3 that multiple arrangement is good is connected on the lock core pole 2, and the spacer 32 of password unit 3, sliding piece 33 can match with the groove 21 on the lock core pole 2; To be connected with lock core pole 2 devices of password unit 3 in sleeve 1, one end of lock core pole 2 is connected the directional hole 112 of sleeve 1, the other end then is connected in the cross-hole 111 of sleeve 1, lock core pole 2 can move back and forth in sleeve 1 but can not rotate, and the position plate 11,12 at sleeve 1 two ends can prevent that lock core pole 2 breaks away from sleeve 1.

As Fig. 5, shown in 9: when unblanking, lock core rod 2 is pushed to assigned address, spacer 32 in the password unit 3 intersects to align with qualification step 22 on groove 21 sides can freely rotate open circles wheel 31 in sleeve 1, because open circles is taken turns the alignment pin 311 of 31 inboards and is stuck in locating slot 321 and stirs 331 li of grooves, during rotation, spacer 32 in the open circles wheel 31 is rotating with open circles wheel 31 under spring 34 pressure and under alignment pin 311 effects, and the sliding piece 33 in the open circles wheel 31 is because its central through hole 332 is an oblong aperture, only pass for lock core rod 2, make that sliding piece 33 can be along with open circles is taken turns 31 rotations together, so when open circles wheel 31 rotates, alignment pin 311 is stirred groove 331 from this and is slided to the next one and stir groove, and send " " sound, also played accurate positioning action when stirring password thereby finished stirring of a numeral; When all passwords all pushed the tram, the groove 322 in the spacer 32 on the intracardiac circle just in time alignd with lock core rod 2 and can move back and forth for lock core rod 2, thereby unblanks; Otherwise in case the password bad of being dialled, 322 of the grooves in the spacer 32 on the intracardiac circle can not align with lock core rod 2, and lock core rod 2 can not be moved back and forth between password unit 3.

As Fig. 6, shown in 10: when revising password, the operator can promote lock core rod 2 to assigned address, spacer 32 and sliding piece 33 that card 24 on the lock core rod 2 promotes along with moving of lock core rod 2 in the open circles wheel 31 move backward, make the locating slot 321 of spacer 32 and the groove 331 of stirring of sliding piece 33 break away from the alignment pin 311 that open circles is taken turns 31 inboards, and this spacer 32 is being stuck under the effect of spring 34 and card 24 on the little blend stop 26, open circles wheel 31 then freely rotates on lock core rod 2, after the operator revises careful sign indicating number, lock core rod 2 is spurred backward, and spacer 32 links together with alignment pin 311 under spring 34 effects once more with sliding piece 33.

Shown in Fig. 7,11: when shutting, then only need back spur lock core pole 2 and upset all passwords and can realize.
