Background technology

At present, known various door goes up and the lock core of motor anti-theft lock for vehicle all is outside being exposed to, fragile lock core is unable to undergo violent tool unblanks by force, because of hoodle and slice, thin piece lock purposes the widest, the slope allows key insert lock core smoothly between tooth position by key and the tooth position, it has been unlocking condition, thereby restriction hoodle and slice, thin piece have only three tooth passwords, the structure of cylinder lock with balls and broad keyhole are easily by single hook with hit technology unlocking such as key, and cost slice, thin piece lock cheap and easy for installation is seen slice, thin piece endoporus length owing to knowing by keyhole, because of its critical defect can only be used for indoor.

Summary of the invention

In order to overcome the deficiency of existing theftproof lock at anti-violence and technology unlocking, the utility model theftproof lock skin adds the steel plate and the anti-technology unlocking of new-type slice, thin piece of anti-violence, brill.

The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises slice, thin piece, lock core, lock tube, steel plate, key, be provided with slot to make way on the key, skin at lock adds a heat treated steel plate, steel plate can change shape according to the purposes of lock, the middle hole shape of steel plate can allow key insert lock core, stay half circular resigning hole of keyhole width on the axle center of lock core, key also is that to be limited with steel plate contact site width be the only about half of slot to make way of keyhole.Described slice, thin piece lock, distance is identical between the most of similar locating slot of slice, thin piece two ends shape, make each slice, thin piece move back and forth apart from identical, slice, thin piece is run into lock tube under spring action, when not inserting key, see that from keyhole the hole shape of slice, thin piece is on a line, key has five tooth passwords, between the tooth right angle row row, key and traditional inserted mode are to lean to one side to insert, and the front end of original-pack key enters in the locating hole of lock core, and key not is a unlocking condition when inserting, original-pack key turn 90 degrees in the process slice, thin piece and is all clamp-oned lock core, the major part of keyhole is blocked by steel plate, and lock core rotates and unblanks, and reaches the purpose that stops technology unlocking and the anti-violence of steel plate and electric drill to be unblanked.

The beneficial effects of the utility model are, can allow like car security coefficient with feel at ease inhabitation, property safety, raising of person, and new-type slice, thin piece lock core low cost, easy for installation, simple in structure adds firm steel plate, and it is powerless to allow technology, violence and electric drill unblank.
