The purpose of this utility model provides a kind of simple and reasonable for structure, makes, easy to use, pick-proof, the tamper bicycle lock that can stop the tapered end of disconnected locking bar to be separated from vehicle body effectively.

Major scheme of the present utility model is: in the end of locking bar, the outside of adapter plate is provided with rank, tapered end location in the tapered end.Wherein, rank, described tapered end location can be the outsides of being located at U-shape lock bar both ends, also can be the protruding rank of the ring-type of being located at the locking bar end; When rank, tapered end location are all established in the end of two locking bars, also can be provided thereon, downside or inboard etc.The rank Gao Yineng on rank, tapered end location stops in the tapered end adapter plate to be separated from it to be advisable effectively.

For the sled that further stops the criminal effectively, tear the lock behavior open, can be in described adapter plate below be provided with lock protecting plate.Both can integral body make, and also can adopt known method of attachment to be connected.In addition, be arranged in the shape of locking bar eye on the adapter plate match with section form and be advisable with rank, tapered end location end side.In described, be provided with between adapter plate and the tapered end and protect the skirt mudwing.

Below by embodiment, the utility model is further described.

Fig. 1 is that the utility model is installed in a kind of position view on the bicycle.

Fig. 2 is a kind of mounting structure figure of the present utility model.

Fig. 3 is the front view of a kind of interior adapter plate in the utility model.

Fig. 4 is the structural representation of a kind of locking bar of the present utility model.

Embodiment: in the outside, both ends of U-shape sword iron (53), metalworking is whittled into a plane, make it section and become the D type, the part of inserting keyhole when its length locks with locking bar is advisable, locking bar (53) the not front end of cutting tip constitutes rank (52), tapered end location, be provided with the interior adapter plate (7) that is formed by punching of the steel plate in the inboard of tapered end (5), its below invagination is bent into lock protecting plate (72), in the relevant position punching out of interior adapter plate (7) two D shape eyelets (71) that match with the locking bar cross sectional shape is arranged.Tapered end (5) protects skirtboard (3) with the pick-proof that is arranged on the mudwing both wings and interior adapter plate (7) is interposed on the upright fork of bicycle (6) successively, and by four screws that its clamping is fixed.Subsequently, trailing wheel is installed on the hind axle of bicycle.

During use, the U-shape sword iron that is installed in the trailing wheel opposite side passes the trailing wheel steel wire, makes the interior lock pin clamping of tapered end on the dead bolt of locking bar, and the outside that is blocked in interior adapter plate (7) is just in time put on the tapered end rank, location (52) on the locking bar.Adopt tool used in crime when stealing the person, just in case with locking bar sled of the present utility model, pincers or sawed-off after, because of the dead bolt clamping of locking bar in tapered end, make interior adapter plate (7) be subjected to tapered end and locate the qualification on rank (52) and can not be removed.

In addition, be arranged on the lock protecting plate (72) of interior adapter plate below, then further improved the difficulty of the disrumpent feelings locking bar of criminal's serviceable tool.

Therefore, the utlity model has simple and reasonable for structurely, the structure and the production technology of changing original lock are hardly made and easy to use, can stop effectively by break tapered end the separating from the vehicle body of locking bar of pincers.Thereby, even the locking bar of bicycle lock is prized, pincers or sawed-off, also difficult this bicycle can being ridden from the crime scene.

Simultaneously, print or be marked at upright fork of bicycle or pick-proof and protect distinctive mark on the skirtboard, and make measures such as thereon steel seal area code, number, also be convenient to the owner of lost property and seek.Stolen car is if be aided with the measures such as service that special mudwing needs to be provided by brand shop old for new service, and then anti-theft effect will be more remarkable.
