Description
Technical field
The utility model relates to a kind of lock technology field, specifically a kind of theftproof lock and key.
Background technique
Lockset is applied very universal in people's daily life, and the various locksets that family, unit use at present are still with bullet
Based on son lock, spring lock has the advantages that structure is simple, easily manufactured, cheap, and existing spring lock is to utilize lock core rotor
The pellet group moving up and down control lock core rotation that is equipped with of outside, then stir lock tongue closure or openness lockset.Due to existing
The structure of spring lock is relatively simple, and pellet group is moving radially along lock core when unlocking, and lock face is arc surface, and lock core because
Rotation needs to guarantee the gap between its lateral surface and lock core sleeve inner wall, causes the precision of pellet group lower, and criminal holds
Technology unlocking easily is carried out using tools such as tinfoil, since the pellet group of existing spring lock is a row along the arrangement of key length direction,
Criminal is inserted into the key of lock core, using the crime work of skeleton key or barbed tool etc by the pellet in lock core
Lockset can be opened easily by being pushed in turn in lock core sleeve;Since the lock core rotation of existing spring lock can drive pulling axis to open lock
Body, by dial, sled, bore when be easily opened, criminal be easy by being inserted into tool in keyhole, by force destroy lock core make its turn
Dynamic, to open lockset, anti-theft performance is poor;Also, it since lockset thickness is limited by the size to half utensil, can only arrange
Three to six group pellets, the telescopic extensions of every group of pellet are between two to four millimeters, therefore pellet is along the combination of key length direction
Number is subject to certain restrictions, and the key secret rate of lockset is low, shaped as key bit repetitive rate is high, is easy mutually to open, is made the person and property of people
Safety is encroached on.In addition, there are also the more complicated locksets such as electronic lock, coded lock at present, although anti-theft performance is preferably,
It since its cost is higher, structure is complex, is easier to damage, causes centainly to perplex to user, especially for old man
It is very inconvenient with children.
Summary of the invention
The utility model aims to solve at least one of the technical problems existing in the prior art.For this purpose, the utility model
One purpose is to propose a kind of theftproof lock and key that can strengthen anti-theft effect.
A kind of theftproof lock according to the present utility model, including housing and housing be built-in with one can turn lock core, lock core
One end is connected with poke rod, wherein the housing is equipped with opening, lock core is equipped with guide groove, the outer surface of guide groove and lock core
It is connected, lock core teeth is equipped in guide groove.
In addition, a kind of theftproof lock according to the present utility model, also has following additional technical feature: according to the utility model
Some embodiments, specific further, in the guide groove to be equipped with lock pearl, lock pearl is located at the top of lock core teeth.
Specific further, the lock core teeth are fixed in lock core.
Specific further, the surface of the lock core teeth is equipped with salient point, and salient point peaks at the inner wall of lock core.
Specific further, the lock core teeth are integrally to form with lock core.
The invention also discloses a kind of and above-mentioned technical proposal matching used keys of theftproof lock, including key sheet
Body is equipped with compatible with lock core teeth wherein the key body is equipped at least one keyhole at the bottom of key body
Key teeth.
Specific further, the key teeth are irregular key teeth or regular key teeth.
It is specific further, it is described to put on outside equipped with preceding lockhole and rear lockhole.
The beneficial effects of the utility model are: 1, using lock core teeth, cooperate the key teeth combination on key body to make
With, prevent self-made tool (such as skeleton key) to be placed in accommodation groove, open by force etc., play promotion anti-theft capability;2, housing hides
Guide groove is kept off, more ugly pearl distributing position can be clearly locked, change existing center lock construction, propose novel theft-prevention structure, help and mention
Rise anti-theft effect.
Detailed description of the invention
The above-mentioned and/or additional aspect and advantage of the utility model from the description of the embodiment in conjunction with the following figures will
Become obvious and is readily appreciated that.
Fig. 1 is structural schematic diagram according to the present utility model.
Fig. 2 is the structural schematic diagram of housing.
It is description of symbols below: lock core 1;Lock core teeth 101;Guide groove 102;Lock pearl 103;Key body 2;Key

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
Below with reference to Fig. 1 description according to a kind of theftproof lock and key of the utility model embodiment.
As shown in Figure 1 to Figure 2, a kind of theftproof lock of the utility model statement, including be provided in housing 4 and housing 4
One can turn lock core 1,1 one end of lock core is connected with poke rod 3, wherein the housing 4 is equipped with opening, lock core 1 is equipped with and leads
To slot 102, guide groove 102 is connected with the outer surface of lock core 1, and lock core teeth 101 are equipped in guide groove 102.This structure passes through
Lock core teeth 101 limit the key of other classes, and the key that this structure can only be used to state could be opened.Lock core teeth 101 make to prevent
It steals and anti-system brings extreme difficulties, the lock core teeth 101 of more evolutions can be played, make the lock core teeth 101 into one of repetition shape
Step is reduced, and helps promotion anti-theft effect.
