Abstract
The utility model discloses an anti-theft structure of a bike. The anti-theft structure of the bike is characterized by comprising a sprocket chain device, a keyhole, a plastic barrier block, a chain locking cover, a chain and a chain positioning aluminum tube. The improvement is mainly used for prevention of burglary of the bike, and the operation is that: an upper tube part of the bike is additionally provided with a penetrating tube element; the chain positioning aluminum tube, together with an upper tube and an lower tube, can be assembled to form a chain positioning area; the chain is matched with the plastic barrier block and can be loosened to have larger length under normal action, thus providing a favorable condition for prevention of burglary. In the design, the chain is hidden, simple, convenient and quick to use, and obviously effective in prevention of burglary, so that lots of inconveniences caused to the consumers are reduced.
Description
Technical field
The utility model relates to a kind of bicycle theft-prevention mechanism, belongs to vehicle safety method field.
Background technology
We know that the antitheft mechanism of the present widespread of bicycle is to rely on himself supporting lock or chain lock or U-shape lock in addition.But the antitheft inefficiency of this lock.The damage of being thought easily, and do not talk, deposit easily easy loss, and also these locks very easily are subjected to weathering or chemical action under unshielded situation.Direct result is to cause the lock life-span to shorten, and the bicycle theft rate is high.This a series of influence has hindered the normal use of bicycle greatly.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model be to provide a kind of can be convenient, fast, safety, the tangible bicycle theft-prevention of anti-theft capability mechanism.
The utility model is achieved through the following technical solutions:
A kind of bicycle theft-prevention mechanism, its feature comprises that bitch chain device, key hole, plastics stopper, chain locking closure, chain, chain are placed aluminum pipe.This improvement is mainly used in the antitheft aspect of bicycle self, its operation is that pipe is partly established one newly and run through pipe fitting on bicycle, chain is placed the put area that aluminum pipe can be assembled into a chain with top tube and down tube, chain cooperates with the plastics stopper, scalable its length under normal effect is the strong condition of antitheft creation.During parking if with chain pull out twine with fixed object after, again the chain cylindrical void is inserted in the bitch chain device hole, just form an anti-theft system, well bicycle and fixture are linked together.Because chain is that self is concealed in this kind of design, and easy to use, quick, anti-theft capability is obvious, for the customer has reduced inconvenience.The anti-joyride device key hole is in the reverse side of bitch chain device, helps the position of key-hole hiding, suitable increase safety factor.The chain locking closure has played the effect of well hiding when not using chain, the also favourable defective that runs through pipe of having hidden is not affected the attractive in appearance of product design.
The beneficial effects of the utility model are: the utility model can reduce the loss by theft rate of bicycle to greatest extent, and the protection personal property is not encroached on the civilized society of building together.Easy to use, quick, anti-theft capability is obvious,
Description of drawings
Fig. 1 is the utility model one exemplary construction scheme drawing
Fig. 2 is the partial enlarged drawing of bitch chain device among Fig. 1.
Among the figure: 1, bitch chain device; 2, key hole; 3 plastics stoppers; 4, chain locking closure; 5, chain; 6, chain is placed aluminum pipe.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
As depicted in figs. 1 and 2: this improvement is mainly used in the antitheft aspect of bicycle self, its operation is that pipe is partly established one newly and run through pipe fitting on bicycle, 6 chains are placed the put area that aluminum pipe can be assembled into a chain with top tube and down tube as shown in the figure, 5 chains cooperate with 3 plastics stoppers, scalable its length under normal effect is the strong condition of antitheft creation.
During parking if with 5 chains pull out twine with fixed object after, again 5 chain cylindrical voids are inserted in the 1 bitch chain device hole, just form an anti-theft system, well bicycle and fixture are linked together.Because 5 chains are that self is concealed in this kind of design, and easy to use, quick, anti-theft capability is obvious, for the customer has reduced inconvenience.Anti-joyride device 2 key holes are in the reverse side of 1 bitch chain device, help hiding the position of 2 key holes, suitable increase safety factor.4 chain locking closures leave 5 chains in the 4 chain locking closures in when not using 5 chains, have so played the effect of well hiding, and the also favourable defective that runs through pipe of having hidden is not affected the attractive in appearance of product design.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
Claims (2)
1. bicycle theft-prevention mechanism, it is characterized in that, comprise bitch chain device, key hole, plastics stopper, chain locking closure, chain and chain placement aluminum pipe, partly establish one newly runs through pipe fitting to pipe on bicycle, described chain is placed the put area that aluminum pipe can be assembled into a chain with top tube and down tube, described chain cooperates with the plastics stopper, scalable its length under normal effect, during parking chain pulled out twine with fixed object after, the chain cylindrical void is inserted in the described bitch chain device hole again.
