Description

A kind of coded lock and its unlocking structure

Technical field

The utility model relates to lock technology field, especially a kind of coded lock and its unlocking structure.

Background technique

Lockset has referred to the utensil of sealing process, it includes lock, key and its attachment, and general explanation is that " must use key What can be absolved seals device ", now, lockset can also be used up, the instructions such as electricity, magnetic, sound and fingerprint are opened in addition to being opened with key It opens.When using common lockset, it is often necessary to tyre key, sometimes bad storage are lost if saving the neither too big nor too little heart, It is rather troublesome.

In view of this, the present inventor furthers investigate for the defects in the prior art, this case is obtained then.

Utility model content

In view of this, it has structure new the purpose of this utility model is to provide a kind of coded lock and its unlocking structure Grain husk, it is simple and quick, the characteristics of being unlocked in the form of password, avoid carrying keys, prevent the risk fallen.

In order to achieve the above object, the utility model uses such technical solution:

A kind of coded lock and its unlocking structure, including lock ring, core, keyhole, cipher buckle, switch, lock body, feature exist In the lock ring right end is connected with lock ring left upper end and is in integral structure, and the core upper end passes through lock ring left-hand notch Interior, the keyhole is set to the lock body lower left corner and is in integral structure with lock body, and the cipher buckle is mechanically connected to lock body right end, The switch is nested in the lock body upper right corner from top to bottom, is equipped with metallic rod, spring, pull rod, movable block, interior cunning inside the lock body Road, slide assemblies, connecting rod, motion bar, shaft, the metallic rod are welded to connect immediately below switch, and the spring upper end is embedding In switch lower left notch, the pull rod right end is fastenedly connected in the bottom of switch left-hand face, and the pull rod left end is buckled in Below movable block, the movable block passes through slide assemblies by motion bar and is connected with shaft, and the inner slide is arc-shaped simultaneously Consistent with core shape, the slide assemblies fit in fixing seat, and the connecting rod left end is with core upper end in integrated Structure, the connecting rod lower end are connected with shaft.

Preferably, the cipher buckle includes lockhole, password seat, and the lockhole is embedded in lockhole top and is in integral structure, The cipher buckle fits in inside.

Preferably, the metallic rod is cylinder, and the radius size of the metallic rod is slightly less than the radius of lockhole.

By using above-mentioned technical proposal, the beneficial effects of the utility model are:

The utility model is a kind of coded lock and its unlocking structure, when cipher buckle being gone to definite value set by oneself first, lock Locking plate on hole can automatically spring open, and at this moment press lower switch, and switch receives during pressure moves down, in metallic rod net lockhole Deeply, spring is extruded, and pull rod then up jacks up movable block, and the movable block jacked up pulls shaft by motion bar, this When so that connecting rod is moved in a circle along inner slide by the flexibility of shaft, to do circumference fortune on interior slideway with movable lock core It is dynamic, and the other end of lock core deviates from lower lock ring, therefore lock core is opened, and can be taken out or be lockked, when hand is unclamped by To the reaction force of spring, so that switch is bounced, lock core locks again, the locking plate if cipher buckle password bad, on lockhole It is that can not flick, presses switch-mode metal bar and blocked by locking plate, can not be unlocked, finally washes cipher buckle password disorderly i.e. again It can；The design can be unlocked or be lockked in the form of password, avoid carrying keys, prevent the risk fallen.

Specific embodiment

To keep the purposes, technical schemes and advantages of utility model embodiment clearer, below in conjunction with the utility model Embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment It is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field is general Logical technical staff every other embodiment obtained without creative efforts belongs to the utility model guarantor The range of shield.

A kind of coded lock and its unlocking structure, including lock ring 1, core 2, keyhole 3, cipher buckle 4, switch 5, lock body 6, It is characterized in that, 1 right end of lock ring is connected with 1 left upper end of lock ring and is in integral structure, and 2 upper end of core passes through lock ring In 1 left-hand notch, the keyhole 3 is set to lock 6 lower left corner of body and is in integral structure with lock body 6, and the cipher buckle 4 is mechanical even It connects in lock 6 right end of body, the switch 5 is nested in lock 6 upper right corner of body from top to bottom, is equipped with metallic rod 61, bullet inside the lock body 6 Spring 62, pull rod 63, movable block 64, inner slide 65, slide assemblies 66, connecting rod 67, motion bar 68, shaft 69, the metallic rod 61 are welded to connect immediately below switch 5, and in 5 lower left notch of switch, 63 right end of pull rod is tight for 62 upper end of spring It is solidly connected in the bottom of 5 left-hand face of switch, 63 left end of pull rod is buckled in 64 lower section of movable block, and the movable block 64 passes through work Lever 68 passes through slide assemblies 66 and is connected with shaft 69, and the inner slide 65 is arc-shaped and consistent with 2 shape of core, described Slide assemblies 66 fit in fixing seat, and 67 left end of connecting rod and 2 upper end of core are in integral structure, the connecting rod 67 lower ends are connected with shaft 69.
