At present, bicycle theft-prevention measure both at home and abroad mainly contains lock and car plate is managed this two kinds of approach, and wherein, lock is the individual precautionary measures, and it is antitheft major measure; Car plate then is the precautionary measures of society, is antitheft ancillary method.

High-grade day by day luxurious along with bicycle, the function of bicycle lock is also become stronger day by day, and design is also advanced day by day.As its technical scheme of " anti-theft bicycle lock " patent (application number is 90225864.8) of having applied for a patent already is that lock is fixed on the wheel hub, thereby makes quite difficulty of picking lock.But, inconvenient operation, most importantly, even if lock reliably, picking lock also is possible again.So it still is not the effectively precautionary measures.

Undoubtedly, the bicycle car plate is the same with the car plate of other car type, as the legal sign that travels of vehicle, the social management of bicycle and antitheft aspect played crucial effect (as the slotting board bicycle number plate that is about to carry out).Present bicycle car plate has two big defectives: the one, lose easily, for this reason, and the patent (application number is 90223132.4) of existing by name " cylinder bicycle car plate ", its thought is that car plate is made cylindrical shape, prevents loss thereby be fixed on the crossbeam of car.Obvious with the present car plate custom of this invention is gone far away mutually, and complicated.Another defective of bicycle car plate also is that the most fatal defective is, as a token of, it is eye-catching inadequately onboard, is difficult to check when transport condition.Because actual conditions such as the volume of bicycle is little, and quantity is huge make this defective become a very thorny difficult problem in administrative department's management bicycle and the bicycle theft-prevention.The patent (application number is 92216288.3) of " bicycle number plate framework " by name has appearred resembling in this respect, and its thought is to do a conspicuous framework for car plate.Obviously, for bicycle, this is installing, all is being difficult to promote in appearance.

The purpose of this utility model is to provide a kind of eye-catching, as to be convenient to supervision by the public and social management bicycle theft-prevention sign lock that indicates.

The technical solution of the utility model purpose is: a kind of bicycle theft-prevention sign lock, it is characterized in that it is made up of fixed block, tapered end, the locking bar that can swing, rotating lock body, tapered end and locking bar are for fixedlying connected, be connected by pin between locking bar and the lock body, fixed block and lock body are arranged at handlebar one side, lock body is arranged between the fixed block, lock body is made up of lock frame, dead bolt, lock core, spring, in the lock frame lock tongue slot is arranged, spring and dead bolt are arranged in the groove, are inserted with the shift fork that connects lock core in the slotted eye of dead bolt top.The utility model fixed block is fixed in the bicycle handle bar, and fixed block is provided with holddown groove, and the top of locking bar is provided with steady pin, and when legal and illegal two condition, the steady pin of locking bar inserts the holddown groove in the fixed block, makes locking bar, lock body fixed-site.Locking bar can be swung on lock body, and lockhole is arranged on the locking bar, and the right outer rim of locking bar is a wedge shape, when non-there won't be any problem state, the lockhole that the swing locking bar makes the dead bolt on the wedge shape outer rim jack-up lock body of locking bar make dead bolt snap in locking bar pins locking bar, and tapered end blocks wheel simultaneously, and wheel is locked.Can fixedly install there won't be any problem sign on the tapered end, when the lock body that can rotate drives locking bar, when tapered end goes to the two positions up and down of handlebar respectively, observably indicates legal and illegal two kinds of sign states that travel of bicycle on handlebar.

The utility model compared with prior art, its remarkable advantage is:

1, fully closely combines by unblanking and two kinds of remarkable different states of locking and being showed, making lock and there won't be any problem indicate, steal the car state even if the success of car stealer's picking lock also can't change it, thereby can't set out on a journey; 2, bicycle there won't be any problem Management flag and lock be linked as integral body, can not lose; 3, there won't be any problem Management flag is extremely obvious, and the administrative staff and the public are come into plain view; When 4, car is locked, pin front-wheel on the one hand, on the other hand front-wheel and handlebar are connected in one, when locking, whole lock can't be dismantled, and makes to lock reliably; 5, lock car and unlock operation are all operated on handlebar, and be easy to operate simple.

Fig. 2 is the schematic diagram of the utility model under non-there won't be any problem state.

Fig. 3 is the schematic diagram of the utility model structure and assembly relation.

Fig. 4 is the sectional view of Fig. 3.

The utility model will be further described below in conjunction with accompanying drawing.

Locking bar in the utility model (2) and tapered end (1) can be connected and be integral body, under state there won't be any problem, lock body (3) drives locking bar (2) and goes to handlebar (4) top, swing locking bar clockwise, steady pin on it is inserted in the holddown groove (11) of the right fixed block (9), make lock body, the locking bar fixed-site is under non-there won't be any problem state, rotational lock (3) and locking bar are to the handlebar below, the counter-clockwise swing locking bar, wedge shape (13) jack-up dead bolt (8) right to use dead bolt of the right outer rim of locking bar is snapped in the lockhole (14) of locking bar, locking bar is pinned in figure (2) position, locking bar can't be swung, simultaneously, tapered end (1) blocks wheel (5) locks wheel, and the steady pin of locking bar (10) inserts in the holddown groove (12) of left side fixed block (7), makes lock body, the locking bar fixed-site, even if make and destroy tapered end, lock body also can't rotate.At locking state, the projection (16) on the lock frame of projection on the locking bar (17) and lock body makes the dead bolt and the external world be in closed state, locks reliably thereby make.When unblanking, rotational lock core (6) drives dead bolt (8) by shift fork (15) and slides backward along the consent of lock body, makes dead bolt withdraw from the slotted eye of locking bar, thus the release locking bar can swing, lock core snaps in the slotted eye of dead bolt by a shift fork.
