Description

Fixed anti-theft device for light bicycle

The utility model belongs to the support with lock of bicycle or other light roadster, particularly a kind of anti-theft device of light roadster.

The anti-theft device of light roadsters such as existing bicycle, tricycle, trolley and motorcycle is that theftproof lock and car is combined integrated mostly.When depositing car, or front-wheel, trailing wheel or the handlebar etc. of pinning car, make car out of hand when motion, reached antitheft purpose.

But the shortcoming of prior art is because lock is easily pried open, or the stone dead wire of its lock or chain are cut off and caused car stolen.What is more is to utilize other traffic delivery means that car integral body is directly stolen.

In order to overcome the above-mentioned deficiency of prior art, the utility model has designed a kind of fixed light roadster anti-theft device, and it promptly is difficult for being pried open, and car integral body is directly transported.

Fixed light roadster anti-theft device of the present utility model is on the overarm brace that the leg by one or more supports, and is fixed with " U " shape lock that can lock wheel and constitutes.The leg of the supporting traverse of this support fixes on the ground.And being housed on crossbeam, more than one " U " shape locks; " U " shape lock is by front end porose " U " shape fork, through the lock pin of " U " shape fork and the tapered end formation that can vise lock pin one end.

The fixed light roadster anti-theft device of this utility model design not only has good theftproof performance, and use also reaches to convenient.When depositing car, wheel is pushed away in " U " of this device shape fork, lock pin inserts the front end that runs through " U " shape fork, in the lockhole that inserts headstock, tapered end on this belt transect vises the termination of lock pin, lock pin can not withdraw from, be about to wheel and lock in " U " shape lock, and be fixed in ground and be configured to one.When picking up the car, open tapered end with key, lock pin is extracted out, and wheel can withdraw from " U " shape lock, and car discharges.The lock pin of this device and tapered end are movable parts, after using, it can be locked again in " U " shape fork standby; Also can take away, use to next bicycle parking place with this device with car.As seen its use is very flexible, and various roadster all can be general.

Description of drawings: Figure of description is the schematic diagram of fixed light roadster anti-theft device of the present utility model.

An embodiment of the light roadster anti-theft device of the utility model design is: the support that the crossbeam (2) that is supported by two legs (1) that are fixed in ground constitutes.On the crossbeam (2) of support, welding several " U " shape locks (3)."
