Description

A kind of Key structure
Technical field
The utility model relates to a kind of Key structures.
Background technique
The door of existing market more preferably prevents from being destroyed by nonnative personnel simultaneously for anti-theft performance, has been gradually increased the thickness of door-plate Degree, this allows for door lock and has to increase also with the thickness of door-plate, and lock thickness is increased, if lock core is arranged in door lock Inside lock body, then the key length for needing to unlock is longer.
To avoid user since key is too long inconvenient to carry, lock body usually is protruded from by what the part of lock core was designed Surface, can also effortless insertion lock core opening door lock with the key of realization short length.But this design also causes Two kinds of hidden danger: it first is that the part due to lock core is designed in the outside of lock body, is easily destroyed in this way by criminal, reduces door The anti-theft performance of lock;Second is that also increasing the difficulty of door lock installation, when door lock is installed, the reserved length of lock core outside is needed Degree will also guarantee the stability that lock core agrees in outer portion and lock body.
In addition, key currently on the market, usually it is integrally formed open-and-shut, the very big power of expense can not by other people To observe the structure of key, if it is the not method for understanding key body structure, it is easy to observe the tooth line structure of key from And copy key, cause security risk.
Utility model content
The utility model intends to solve the technical problem by providing a kind of Key structures, and it is suitable for opening door locks.
To achieve the goals above, the utility model discloses a kind of Key structures, including the shank of the key;It is fixed with the shank of the key Connection and rotatable key bit;It further include the cavity that the shank of the key back is set;With the shank of the key far from key cephalic par The key buckle being fixedly connected;And the key block that key bit can be prevented freely to pop up outward is set in cavity.Key can It folds, accordingly even when the length of key bit design is longer, key bit can also be rotated to the shank of the key, reduce key by folding Total length, the carrying for the person of being convenient to use.
Preferably, the key block is set on a spring, and the spring one end is against on key block, and one end is against On the shank of the key.The purpose of design of key block and spring is to be that key block can hinder after key bit is rotated into cavity Gear key bit pops up outward, reduces the chance that criminal observes key bit tooth line structure in this way.
Preferably, one is provided in the key block can accommodate semi-enclosed cylindrical cavity of spring, in the shank of the key Portion is provided with a spring gear, and the spring one end is against the top of cylindrical cavity, and the other end is against the spring shelves inside the shank of the key On position.
Preferably, the plush copper that key bit can be stopped freely to pop up outward is provided on the key block.
Preferably, the shank of the key and key bit pass through the stud that key bit can be made to rotate freely and the fixed company of screw It connects.The purpose of design of stud is primarily to key bit easier can rotate.
Preferably, the key buckle is fixedly connected by positioning pin with the shank of the key.
Preferably, two pieces of decoration baffles are posted in the outside that the key block is engaged with the shank of the key.The design of baffle is main It is the beauty that ensure that key entirety.
Preferably, key ring is provided on the downside of the key buckle.Key ring can be worn designed for carrier Sets of cords or other modes, it is easy to carry.
Preferably, the surface of the key block is provided with strip projected parts.The designs of strip projected parts so that user to It is unlikely to skid when lower promotion key block.
Preferably, the key buckle also includes a buckle that may make the shank of the key and key buckle to be closely connected in a clamped manner Boss, to prevent key chain plate from falling off on the shank of the key.
Beneficial effect possessed by the utility model is:
1, the foldable design of key bit, both guarantees to design longer key bit, is entirely located at lock body to adapt to lock core Internal door lock, thus can the anti-theft performance of lifting door lock be not easy to be destroyed, and be easily installed;In turn ensure key entire length It can adapt to the carrying requirement of user, convenient for the carrying of user.
2, the rotation of key bit to cavity, key block can prevent key bit from popping up, and reduce criminal and observe key The chance of key bit tooth line structure.The Combination Design of key block and spring simultaneously, user only need gently one to draw and can use, letter Dan Yicao.

Specific embodiment
In the utility model description, the orientation or positional relationship of the instructions such as term " on ", "lower", " preceding " and " rear " is base In orientation or positional relationship shown in the drawings, it is merely for convenience of description the utility model rather than requires the utility model necessary It is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
As shown in 1-6, a kind of Key structure of the present embodiment, it is characterised in that including key bit 1 and the shank of the key 2, the key Key bit 1 is fixed together by stud 12 and screw 13 with the shank of the key 2.In the present embodiment, the key bit 1 can be along Stud 12 rotates freely 180 degree.
The back of the shank of the key 2 is provided with a cavity 24, and the shank of the key 2 is provided with one far from the end of key bit 1 Key buckle 23, the located pin 231 of the key buckle 23 are fixed on the shank of the key 2;The key bit 1 can be along stud 12, which are rotated up 180 degree, is folded in cavity 24;The cavity 24 is provided with key block 21 and bullet far from one end of key bit 1 Spring 211, described 211 one end of spring are set in the key block 21, and the other end is against on the shank of the key 2, specifically in this reality It applies in example, one is provided in the key block 21 can accommodate semi-enclosed cylindrical cavity 212 of spring 211, in the shank of the key 2 A spring gear 214 is arranged in portion, so that 211 one end of the spring is against the top of cylindrical cavity 212, the other end is against the shank of the key 2 On internal spring gear 214.In addition, the surface of the key block 21 is provided with strip projected parts, so that user is downward When pushing key block 21, it will not skid.Plush copper 213 is additionally provided on the key block.
Further, two pieces of decoration baffles are posted in the outside that the key block 23 is engaged with the shank of the key 2, in order to avoid positioning pin 231 fall off, but also the entirety of key is more aesthetically pleasing.
Further, it is provided with key ring 233 on the downside of the key buckle 23, to wear rope, convenient for users to carrying Key.
Further, the key buckle 23 also includes a buckle boss 232, and the buckle boss 232 can be tight with the shank of the key 2 Close be connected together avoids key chain version 23 from falling off on the shank of the key 2.
Using the embodiments of the present invention, in key closed state, Fig. 4-5 is seen, spring 211 is in key buckle at this time Under 23 reaction forces given, the plush copper 213 of key block 21 is pushed to fit closely the top of key bit, prevent key bit 1 to Outer pop-up;When using key unlocking, user pushes down on key block 21, at this time the top of plush copper 213 and key bit 1 point From, so that the gear of key bit 1 releases, user then can be taken off key bit 1 and rotate 180 degree to the direction far from the shank of the key 2, into Row is unlocked.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality The mode of applying is changed and is modified.Therefore, the utility model is not limited to specific embodiment disclosed and described above, right Some modifications and changes of the utility model should also be as falling into the protection scope of the claims of the present utility model.In addition, to the greatest extent It is used some specific terms in pipe this specification, these terms are merely for convenience of description, not to the utility model Constitute any restrictions.
