Given this, the purpose of this utility model is to provide a kind of handsome in appearance, easy to use, bicycle concealed type steering lock that theftproof is good that does not influence bicycle.

The utility model adopts in the vehicle frame with the bicycle of lock installing, and run through the seat tube of phase suit and front fork standpipe and the tap that turns to of locking bicycle is realized its purpose with the locking bar of lock.

Bicycle concealed type steering lock of the present utility model (referring to accompanying drawing), the lock body (1) that includes lock core (2) with the lock core transmission locking bar of continuous cropping stretching motion (8) mutually, above-mentioned lock body is installed in its vehicle frame transverse tube (4) that turns to the bicycle that links to each other with the front fork standpipe of tap, and the vehicle frame lockhole (9) and the leading lockhole (11) that can cooperate simultaneously with locking bar are arranged respectively on the seat tube (5) of the phase suit of bicycle and front fork standpipe (10).

Above-mentioned lock body (1) is along the horizontally set of vehicle frame transverse tube, and it has the front end of keyhole to run through tube wall, and there is the rotating disk (7) that is connected with lock core (2) its rear end, and above-mentioned locking bar (8) is eccentric with rotating disk and is hinged.

There is location protruding (3) front portion of above-mentioned lock body (1), between the tube wall of locating protruding and vehicle frame transverse tube, Spring Card (6) is arranged, above-mentioned locking bar (8) is L-shaped, and L shaped cross bar portion links to each other with rotating disk, and there is the conduit (12) that matches with L shaped vertical pole portion in said vehicle frame lockhole portion.

Use bicycle concealed type steering lock of the present utility model, lock core with the key turns lock body, drive locking bar and make stretching motion, when needs lock car, make locking bar to protracting, insert vehicle frame lockhole and leading lockhole, the seat tube and the front fork standpipe of bicycle are fused, the front fork standpipe that links to each other with tap can not be rotated, and bicycle can not ride and carry out, and realizes antitheft; When needs are used car, locking bar is contracted backward, withdraw from vehicle frame lockhole and leading lockhole, the seat tube of bicycle separates with the front fork standpipe, the front fork standpipe recovers rotating function, and the tap that links to each other with the front fork standpipe recovers the handling maneuver function, the rideable and implementation of bicycle.

Said structure of the present utility model makes it have following advantage and effect.

One, lock body of the present utility model, locking bar are arranged in the vehicle frame pipe of bicycle, constitute the concealed type structure, neither influence the moulded and attractive in appearance of bicycle, are difficult for destroyedly again, and its theftproof performance is good.

Two, bicycle locking bar of the present utility model, the structure that cooperates simultaneously with the leading lockhole of the vehicle frame lockhole of the seat tube of suit mutually and the front fork standpipe that links to each other with tap, handling maneuver tap that can locking bicycle can not normally move bicycle and realizes antitheft.

Three, the utility model is made of the lock body of common structure, the locking bar of rod, and is simple in structure, easy to manufacture.

Bicycle concealed type steering lock of the present utility model is specially adapted to and the bicycle integrated design, when making bicycle, is installed in the bicycle, makes and offer the user simultaneously with bicycle.

Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
