Abstract

The utility model discloses a theftproof bicycle. A coded lock integrated with a tripod frame into a whole is arranged on the bicycle, the coded lock comprises a locking head and a locking lever, the locking head comprises a locking frame and a plurality of locking discs, the locking head is fixed on a slash lever on one side of a bicycle tripod frame, the locking lever is fixed on the slash lever on the other side of the bicycle tripod frame, and the both are positioned in the symmetrical location and are used for respectively penetrating through the two slash levers, and the locking discs are welded in the locking frame. The coded lock of the utility model is different from the common lock, and the utility model has the advantages of long service life, simple structure, practicality, low cost, and good effect. The locking head, the locking lever and the bicycle tripod frame are generated into a whole, and the common way of a slough worker is to damage the lock. In the technology, if the coded lock is damaged, while the tripod frame is damaged, the lock can not be restored, the stolen vehicle can be identified easily, and the utility model effectively prevents the bicycle from being stolen.

Description

Anti-theft bicycle

Technical field

The utility model relates to a kind of anti-theft bicycle, relates in particular to a kind of bicycle that can prevent effectively that stolen back pin is dirty.
