The specific embodiment
Extremely shown in Figure 9 as Fig. 1, be a kind of coded lock of the utility model, comprise lock body 1, lock core 2 and lock bridge 6, be provided with the transition rings 3 and the cipher wheel 4 that cooperatively interact in the lock body 1, transition rings 3 is provided with stopper slot 31, transition rings 3 internal ring walls are provided with ring-type locking layer 33, locking layer 33 is provided with an opening 34, lock bridge 6 is provided with the locking projections 61 corresponding with opening 34, transition rings 3 external annulus middle part is provided with transmission projection I32, cipher wheel 4 internal ring wall tops are provided with the transmission projection II42 corresponding with transmission projection I32, carry out transmission in the gap that transmission projection I32 embedding transmission projection II42 forms; Transition rings 3 and cipher wheel 4 cross-under are on lock bridge 6, and the surface markers 41 of cipher wheel 4 can adopt numeral or letter, and preferred cipher wheel 4 adopts 3～5, and the quantity of cipher wheel 4 can certainly be set according to the actual needs.
Be provided with the linkage that is used to cooperate stopper slot 31 between transition rings 3 and the lock core 2, linkage comprises connecting rod 5, connecting rod 5 one ends are connecting rod drive end 55, connecting rod 5 other ends are connecting rod driven end 56, the end of connecting rod drive end 55 is provided with arc notch 53, lock core 2 is provided with the fluting 23 corresponding with arc notch 53, connecting rod drive end 55 embeds in the fluting 23 of lock core 2, connecting rod driven end 56 is provided with the spacing preiection 51 corresponding with stopper slot 31, spacing preiection 51 can embed and pin transition rings 3 in the stopper slot 31, connecting rod 5 is that connecting rod drive end 55 is connected with spring 21 near lock core 2 one sides, spring 21 other ends prop up lock body 1 and are used to promote connecting rod 5, connecting rod 5 is provided with guide protrusions I52, lock body 1 is provided with guide protrusions II22, the difference cross-under of spring 21 two ends is on guide protrusions I52 and guide protrusions II22, certainly, spring 21 also can directly be fixed, be that spring 21 1 ends are fixedly connected on the connecting rod 5, spring 21 other ends are fixedly connected on the lock body 1, original state spring 21 is compressed, the rotating fulcrum 54 of connecting rod 5 is fixed on the lock body 1, and connecting rod 5 activity supporting point 54 that can rotate rotates.
As shown in Figure 7, before with the decoding key unlocking: on the one hand, the fluting 23 of lock core 2 props up connecting rod drive end 55 bottoms, and the restoring force of spring 21 can't promote connecting rod drive end 55 rotates its activity supporting point 54 that rotates; On the other hand, because the password bad that cipher wheel 4 shows, the spacing preiection 51 on the connecting rod 5 is not corresponding with stopper slot 31 positions on the transition rings 3, and spacing preiection 51 is against on the external annulus of transition rings 3.
Promptly rotate counterclockwise lock core 2 with the decoding key unlocking.
As shown in Figure 8, after with the decoding key unlocking: the fluting 23 of lock core 2 breaks away from connecting rod drive end 55 bottoms, because the password bad that cipher wheel 4 shows, spacing preiection 51 on the connecting rod 5 is not corresponding with stopper slot 31 positions on the transition rings 3, spacing preiection 51 is against on the external annulus of transition rings 3, and spring 21 still can't promote connecting rod drive end 55 rotates its activity supporting point 54 that rotates.
Clockwise or rotate counterclockwise cipher wheel 4 and give original password for change.
As shown in Figure 9, rotational password wheel 4 is to original password: the locking projections 61 on the lock bridge 6 is corresponding with opening 34 on transition rings 3 internal ring walls, the locking action that transition rings 3 is removed lock bridge 6, the spacing preiection 51 on the while connecting rod driven end 56 is corresponding with the stopper slot 31 on the transition rings 3.This moment is under the effect of spring 21 restoring forces, on the one hand, spring 21 promotes connecting rod drive ends 55 activity supporting point 54 that rotates and rotates, rotate activity supporting point 54 of connecting rod driven end 56 upwards rotates, spacing preiection 51 embeds in the stopper slot 31, makes 4 position-limiting actions of 5 pairs of cipher wheel of connecting rod, and cipher wheel 4 can't be rotated again, show this moment is a proper password, and rotational password wheel 4 draws whole passwords one by one then; On the other hand, arc notch 53 ends of connecting rod drive end 55 still are positioned at the fluting 23 of lock core 2, do not detach fluting 23.
When promptly clockwise rotating lock core 2 with decoding key locking, fluting 23 inwalls of lock core 2 can be pushed down arc notch 53 ends of connecting rod drive end 55, connecting rod drive end 55 is rotated, and activity supporting point 54 upwards rotates and compression spring 21, simultaneously connecting rod driven end 56 activity supporting point 54 that rotates rotates, the stopper slot 31 that spacing preiection 51 on the connecting rod driven end 56 breaks away from the transition rings 3, releasing is to the locking of cipher wheel 4, owing to learnt original password, therefore arbitrarily can pin coded lock again behind the rotational password wheel 4.
