Convenient anti-theft bicycle special lock integrating bicycle and lock

Abstract

The invention relates to a convenient anti-theft bicycle special lock integrating a bicycle and a lock. Two forming semicircles are fastened and combined to form a whole circle through bolts, the combined whole circle is named as a unit, all units are respectively independent and are mutually cross correlated, a lock body unit is shaped as a column, two sides of which are provided with flange edges, the flange edges are provided with threads and through holes with steps, the front semicircle is provided with a threaded hole filled with a basket on a cut plane, the rear semicircle is provided with a lock head in a hole of a lug boss, a simulation handle penetrates through the center of the lock head, the lock body is internally provided with a groove with gradient, the groove is internallyprovided with a spring and a marble, a drive plate unit is arranged above the marble, the marble is separated from a simulation handle middle shaft, meanwhile, the simulation handle middle shaft can freely rotate, and a bicycle can be driven, or else, a key is reversely rotated to be drawn out for loosening a brake line, the marble is clung to the simulation handle middle shaft under the spring tension, the marble is driven to rotate if the simulation handle middle shaft acts under the friction force, the simulation handle middle shaft is locked if rotating towards the small head direction ofthe groove, the more the simulation handle middle shaft rotates towards the big head direction, the more the front wheel deflects until the front wheel deflects transversely with 90 degrees, and the bicycle can not be pushed, thereby achieving the purpose of locking the bicycle.

Description

Technical field [0001] The invention relates to a lock, in particular to a special bicycle lock with integrated convenience and anti-theft. Background technique [0002] At present, in the domestic market, there are not many types of bicycle locks, only "Baishun lock" and "Tiantang lock" are common, but they are all driven by rack and pinion, with complex structure, high cost, and not very flexible, like a chain. Locks, wire rope locks, U-locks, etc. are also inconvenient to use. Contents of the invention [0003] In order to overcome the deficiency that there are not many types of bicycle locks in the existing domestic market, the invention provides an improved special lock for bicycles with integrated locks for convenience and anti-theft. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] For the bicycles already on the market, the present invention adopts two formed semicircles to be fastened by screws to form...
