Description

A kind of cipher wheel padlock

Technical field

The utility model relates to a kind of cipher wheel padlock.

Background technology

Existing cipher wheel padlock, comprise lock body, lock bridge, lock body is provided with cipher wheel lock core and latch hook, lock bridge comprises and is fixed on fixed end on lock body and tapered end, cipher wheel lock core is provided with latch hook and matches with tapered end, and traditional cipher wheel lock core comprises multiple cipher wheels and locking bar, password wheels comprise the cam of character wheel, rotate by rotating character wheel band moving cam, make cam to locking bar moving-limiting and lift restrictions, realize locking and the unlatching of cipher wheel lock core, due to the restriction of the modeling structure of lock body and the installation site of password wheels, the locking of cipher wheel lock and unlocking realizes general all cooperation along the movement of the axial direction of cam by locking bar and lock body switch, existing cipher wheel lock core adopts cam outer ring to be provided with the structure of depression and locking bar cooperation, when the depression of all cams is simultaneously facing to locking bar, locking bar enters depression towards the radial direction of cam, thus reach the object of opening cipher wheel lock core, and the mode that this locking bar moves unblock along the radial direction of cam also needs by intermediate conversion connector, by moving direction, the axial direction converted to along cam moves, just can reach locking bar to lift restrictions to lock body switch, intermediate conversion connector one end coordinates with locking bar, the other end matches with lock body switch, which coordinates inefficacy that cipher wheel lock core all will be caused to work, add inefficacy hidden danger, and cipher wheel is locked to the lock body of this small volume, it is better that its structure is more simply put, many parts just mean more cost, many one assemble flow, many links that lost efficacy together.

Utility model content

Technical problem to be solved in the utility model is: provide the cipher wheel padlock that a kind of structure is simple, reliability is high, cost is low.

In order to solve the problems of the technologies described above, technical solution of the present utility model is such: a kind of cipher wheel padlock, comprise lock body, lock bridge, lock body is provided with cipher wheel lock core and latch hook, lock bridge comprises and is fixed on fixed end on lock body and tapered end, latch hook matches with tapered end, described cipher wheel lock core comprises multiple cipher wheels and locking bar, described password wheels comprise the cam of character wheel, described character wheel band moving cam rotates, described cam inner ring is provided with positive stop lug boss, described positive stop lug boss is provided with cam and installs groove, positive stop lug boss is provided with inclined-plane and " C " shape locking face, described inclined-plane is positioned at cam and installs groove two side position, inclined-plane connects sidewall and " C " the shape locking face that cam installs groove, described " C " shape locking face is positioned at the position except inclined-plane and cam installation groove, described locking bar is provided with the projection consistent with cam quantity, each projection matches with the inclined-plane on corresponding cam or " C " shape locking face, when projection on locking bar matches with the inclined-plane on corresponding cam, cipher wheel lock core removes the restriction to latch hook, latch hook can be departed from and the coordinating of tapered end, when projection on locking bar matches with " C " the shape locking face on corresponding cam, cipher wheel lock core locking restriction latch hook moves, latch hook cannot be departed from and the coordinating of tapered end, by lock bridge locking.

The beneficial effects of the utility model are: due in above-mentioned technical solution, the locking of cipher wheel lock core and unlatching control locking between lock bridge and lock body and unlatching, and the cam inner ring of cipher wheel lock core is provided with positive stop lug boss and cam installs groove, all projections on locking bar and the cam on corresponding cam install groove position corresponding time, namely all cams are all driven by character wheel and turn to unlocking cipher position, this hour locking lever can move to cipher wheel lock core enable possition, namely cipher wheel lock core removes the restriction to latch hook, now promote latch hook releasing latch hook by lock body switch and can open padlock to the cooperation of lock bridge tapered end, when needs locking padlock, the tapered end of lock bridge is inserted latch hook cooperation position, and rotate the rotation of one or more character wheel band moving cam in this case, the cam rotated then projection by side inclined-plane moved to along inclined-plane near the side of sidewall that cam installs groove near " C " shape locking face, and finally move on " C " shape locking face, inclined-plane drives projection and locking bar to move the axial distance on an inclined-plane along the axial direction of cam in the process, and, the projection of locking bar is limited in locking position when coordinating with " C " shape locking face, now cipher wheel lock core locking, latch hook cannot depart from and the coordinating of tapered end, the tapered end of lock bridge is locked on lock body, thus achieve the locking of padlock, the cipher wheel lock core of this padlock only needs password wheels and locking bar can realize locking and unlatching, no longer need intermediate connector, therefore it is simple that a kind of cipher wheel padlock that the utility model provides has structure, reliability is high, the feature that cost is low.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
