Description

A kind of novel cipher padlock

Technical field

The utility model is related to coded lock fields, more particularly to a kind of novel cipher padlock.

Background technology

Password lock is internal, and there is code component, code component to include password wheels, adjust code wheel and wheel shaft.In the prior art, Code wheel is adjusted to be sheathed on outside wheel shaft, during unlocking coded lock, wheel shaft needs opposite tune code wheel to be in axial sliding.Due to adjusting code Wheel belongs to a face with the contact of wheel shaft side wall and contacts, and during wheel shaft is in axial sliding, the friction that wheel shaft side wall is subject to is made With larger so that the side wall of wheel shaft is easy to be worn.

Invention content

In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of novel cipher padlock, can reduce wheel Axis is in the abrasion being subject in the process that reciprocatingly slides.

In order to solve the above-mentioned technical problem, technical solution used by the utility model is：

A kind of novel cipher padlock, including axle sleeve, wheel shaft and latch hook, the axle sleeve are set in outside the wheel shaft, institute Stating wheel shaft can slide along the axial reciprocating of the axle sleeve, be arranged with password solution lock set outside the axle sleeve, work as cipher hang lock When in locked state, password solution lock set limits the sliding of wheel shaft, to which latch hook is supported to latch hook and cannot be slided by wheel shaft；When close When code padlock is in the unlocked state, the limitation that password unlock module cancels slide wheel shaft, wheel shaft, which can slide into, is not pressed against lock Hook, so that latch hook can slide into unlocking.

Specifically, password solution lock set several groups tune code wheel and password wheels, each adjust is arranged with password wheels outside code wheel, when close When code padlock is in locked state, the sliding of code wheel limitation wheel shaft is adjusted, to which latch hook is supported to latch hook and cannot be slided by wheel shaft；When close When code padlock is in the unlocked state, code wheel is adjusted to release the limitation slided to wheel shaft, wheel shaft, which can slide into, is not pressed against latch hook, so that Latch hook can slide into unlocking.

Specifically, the axle sleeve is provided with side channel in an axial direction, and the wheel shaft side wall is equipped with several first stop in an axial direction Convex block, first stopping projection exceed the outer wall of the axle sleeve by the side channel, and the inner wall for adjusting code wheel is set There are defining flange, the defining flange to offer supply first stopping projection to pass through first by notch, work as cipher hang lock When in locked state, the defining flange is pressed against first stopping projection, so that wheel shaft cannot slide；At cipher hang lock When unlocked state, the first stopping projection is mutually aligned with first by notch, so that wheel shaft can slide, to make latch hook slide It moves to unlocking.

Specifically, the axle sleeve outer wall is equipped with several second stopping projections in an axial direction, and the defining flange offers For second stopping projection pass through second by notch, when cipher hang lock is in locked state, second stop is convex Block is pressed against the defining flange, to which axle sleeve hinders that code wheel is adjusted to slide axially；When cipher hang lock is in the unlocked state, the One stopping projection is circumferentially aligned with each other by notch with first, and the second stopping projection is circumferentially right each other by notch with second Standard can will adjust code wheel to be pushed axially to adjusting code wheel to be detached from password wheels, thus allow for adjusting code at this time.

Specifically, including code sliding block and drive sleeve, the drive sleeve is adjusted to be sheathed on the tail portion of the axle sleeve, the transmission Set can sliding axially along the axle sleeve, the tunes code sliding block can move back and forth, the drive sleeve and the tune code sliding block It is driven contact of incline plane by a pair, it is described to adjust the sliding of code sliding block that the drive sleeve be driven sliding along the axial direction of the axle sleeve It is dynamic, adjust code wheel to being detached from password wheels to which the drive sleeve pushes.

Specifically, the head end of the wheel shaft have stop inclined-plane, the latch hook have stop notch, the stop inclined-plane with Metal ball is equipped between the stop notch, when coded lock is in locked state, the stop inclined-plane supports the metal ball To the metal ball partially into the stop notch, to limit the movement of the latch hook；When cipher hang lock is in the unlocked state When, the wheel shaft can be moved to the stop inclined-plane and be not pressed against the metal ball, so that the metal ball can integrally be left The stop notch, to which the latch hook can slide into unlocking.

Specifically, the head of the axle sleeve is arranged with resetting spring, and one end of the resetting spring is pressed against the wheel shaft The head of set, for the other end of the resetting spring against tune code wheel, resetting spring can will adjust code wheel be pushed into reset.

Specifically, the wheel shaft tail end have receiving hole, the receiving hole be equipped with pushing top spring, the one of the pushing top spring Against the roof of the receiving hole, the other end of the pushing top spring is pressed against the inner wall of the tail end of the axle sleeve, described to push away at end Spring is pushed up the wheel shaft to be pushed towards the direction of its head end.

The beneficial effects of the utility model are：

The utility model axle sleeve therein is set in outside wheel shaft, and wheel shaft can be slided along the axial reciprocating of axle sleeve.Wheel shaft To need the part frequently to reciprocatingly slide, axle sleeve to be set in outside wheel shaft, the opposite sliding of axle sleeve and wheel shaft is that face connects with face It touches so that the friction that wheel shaft side wall is subject to substantially reduces, so as to reduce wheel shaft in the abrasion being subject in the process that reciprocatingly slides.
