For realizing that the technical measures that the purpose of this utility model is taked are:

A kind of anti-theft puzzle lock comprises core body and cryptographic system.Cryptographic system is installed in the rear portion of core body, it comprises a password bar, insuring the volute spring that resets is enclosed within on the password bar, its two ends prop up bar handle and insurance locator card respectively, slide at password rod rear end suit successively then and insure and teeth groove password cover, password masthead end exposed portions serve has one or several special-shaped teeth groove.

Wherein slide insurance for having the annulus of three equally distributed vertical rods, ring diameter and password bar are complementary in it, password has put three circular holes, and the vertical rod in its size and position and the insurance of sliding is suitable, and password puts and also is provided with the heteromorphic teeth that one or several varies in size.There is circular hole at the center of the main body of insurance locator card, the diameter coupling of its aperture and password bar, and the profile of main body is circular or other shape, extends a right angle bar vertically upward in its extension, the outer end of right angle bar is stuck on core and the lock body.

Be exclusively used in open above-mentioned coded lock key it comprise key body, a teeth groove bar, a teeth groove overlaps and back stop, one end of teeth groove bar, cover all has a password release handle, wherein the other end of teeth groove bar has corresponding teeth groove, the size and the distribution of the teeth groove in its size and distribution and the lock on the password bar are complementary, the teeth groove that password puts in the size of the teeth groove that the other end of teeth groove cover is opened and distribution and the lock is complementary, tooth, groove cover are enclosed within on the teeth groove bar, and back stop places between teeth groove bar and the key body.

During use, have only two groups of passwords when key and lock, could promote the insurance of sliding, open core body locator card rotation lock core simultaneously to good orientation.Size according to lock can be provided with one or more groups password.

Compared with prior art, the technique effect that adopts the utility model technical measures to be reached:

Because anti-theft puzzle lock of the present utility model adopts two groups of size teeth groove orientation location interlocks, therefore, secret coefficient is bigger, as long as password is on the key transferred in the back of unblanking, just forms one group of new password, and other people imitate the key of joining can not open this lock.
