The utility model design-calculated purpose: design car, lock integral type anti-theft bicycle that a kind of anti-theft column lock and bicycle be assembled into one, reach that anti-theft is strong, lock is not lost, purpose easy to install.

Structure design of the present utility model: car, lock integral type anti-theft bicycle, form by anti-theft column lock and bicycle, anti-theft column lock before lock housing is fixed on bicycle on the joint or on the center tap; The anti-theft column lock lockhole is ditto joint perforate or corresponding with the center tap perforate; Anti-theft column lock is by lock core, dead bolt, spring, lock housing, lockhole and be processed with locked groove on it, the locking bar of locked groove constitutes down, expose be equipped with in the lock housing of anti-theft column lock lockhole and key hole lock core and key through lock core can stir debouch insert lockhole, preceding the last locked groove on the locking bar of joint perforate, front fork tube perforate or center tap perforate and axis perforate under the dead bolt of locked groove, the other end and the spring of dead bolt join; Locking bar is cylindrical, and last locked groove on it and following locked groove are the annular vertical groove; Last locked groove uses when depositing locking bar, and following locked groove uses during as locking bicycle.

The advantage that the utlity model has, characteristics and good effect:

1, anti-theft lock structure is simple, produces, assembles easily;

2, existing bicycle is improved and installs anti-theft column lock conveniently;

When 3, bicycle parking is not used, with front fork tube or axis secure lock, preceding of bicycle or axis can not be rotated, lose, avoided giving many families to bring inconvenience in life and economic loss but actv. prevents bicycle with anti-theft column lock;

4, locking bar is put into lockhole and can be locked by dead bolt, is difficult for losing, and is easy to use, safe and reliable.
