Abstract

The utility model relates to a rotary internal lock theftproof bicycle, the lock of which is arranged at the combination of a bicycle medial axis and a machine thigh transmission. The lock has the function of locking vehicles and also is used as a nail that connects the medial axis and the machine thigh, so the vehicle locking and theftproof can be realized in the connector. The difficulty that an outer padlock of a bicycle is easily stolen and after stealing a criminal can ride and run away can be changed basically. The utility model has the advantages that the lock is secret and nothing can open or break the lock without the key, and the accuracy is high. The lock uses the technology of two ends elastic lock and the safety factor is high, which can increase the function of theftproof greatly. The utility model is characterized in that the bicycle loses the function of transmission and motion under the condition of locking bicycles and the theftproof applicability is high. The utility model is suitable for the bicycle plants to produce both the new type and upgrade theftproof bicycles and elements. The present bicycle (including personal own) can be remodeled to the theftproof bicycle and is suitable for the bicycled transport facility like the tricycle, etc.

Description

Rotate the internal lock anti-theft bicycle

Affiliated technical field:

The utility model relates to a kind of theft-proof device for bicycle, especially reaches the bicycle walking-replacing tool that avoids theft by rotating internal lock.

Background technology:

At present, known bicycle all takes outer padlock next antitheft.Though bicycle lock is of a great variety, form is different, and the anti-theft security coefficient is little, no matter the sort of type lock all belongs to from the bicycle outside and adds padlock enforcement anti-theft feature, outside lockset is exposed to, is easy to implement crime to the thief and provides convenience.According to investigations, bicycle of little pilferage only needed just lock can be pried open for tens seconds, escaped by bike, went everywhere without any hindrance here, and the stolen case of bicycle increases repeatedly, and is hard to guard against.

Summary of the invention:

In order to overcome the existing bicycle little deficiency of stolen and outer padlock safety factor easily, the utility model provides a kind of rotation internal lock anti-theft bicycle, fundamentally change current bicycle lock and do not lock interior defective outward, remove bicycle owner's antitheft suffering, and can prevent the problem that the criminal can not escape by bike.

The technical scheme that its antitheft problem that solves the utility model adopts is: with the bicycle lock device in the bicycle transmission structure body, lock body is tool lock car function both, be again the drift bolt that connects axis 1 and machine thigh 2, at connector internal implementation lock car, lock is hidden and is not revealed, stealing the car criminal at lock car state is difficult to lock body is destroyed, except that key, lock can't be opened or pried open, the outside adds the lock body protective cover simultaneously, integral body does not expose and weather proof is corroded, and reaches the purpose that can prevent that bicycle is stolen easily.

The beneficial effects of the utility model are, new-type replacement bicycle traffic walking-replacing tool, and lockset combines with car body, and lockset utilizes the technology of two ends lock bullet, and safety factor is big, and sound construction is easy and simple to handle, and antitheft applicability is strong.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an integral structure of the present utility model elevation profile constructional drawing.

Fig. 2 is the outward appearance front elevation of first embodiment.

Fig. 3 is the external view of second embodiment.

Fig. 4 is the external view of the 3rd embodiment.

Among Fig. 1,1. axis, 2. machine thigh, 3. lock body, 4. lock core, 5. lock bullet, 6. spring is 7. reinforced screw, 8. pinning.

The specific embodiment:

In Fig. 1, left end machine thigh (2) is opened a notch with left end axis (1) top, junction, axis (1), machine thigh (2) connect by lock body (3), lock body (3) is made of lock core (4), lock bullet (5), spring (6), pinning (8), lock body (3) places in the drive mechanism body of bicycle left end axis (1) and machine thigh (2), lock body (3) had both been had a lock function, had the drift bolt function again.

In embodiment illustrated in fig. 2, when depositing bicycle, unblank core (4) rotational lock (3) and machine thigh (2), rotate 180 degree around axis (1), the foot-operated machine thigh of bicycle left end is inserted in the bicycle triangle crossbeam, utilize the foot-operated machine thigh of left end to make locking bar, by lock core (4) rotational lock (3), upspring pinning (8) locking of spring (6) reaches lock car purpose.After bicycle locking, left end machine thigh (2) is ridden into one suitable with the transmission of right-hand member machine thigh, and bicycle loses transmission agency, reaches the purpose that can not ride.

In the embodiment shown in fig. 3, axis (1), machine thigh (2), lock body (3) connector internal implementation lock car function, lock body (3) is hidden in axis (1), the machine thigh does not expose sound construction in (2).

In the embodiment shown in fig. 4, axis (1), machine thigh (2), lock body (3) connector add protective cover, prevent that (1), (2), (3) from locating erosion by wind and rain and getting rusty.
