Description

Bicycle function theftproof lock

The utility model relates to a kind of bicycle lock, especially the bicycle thigh is designed to lock, makes the function of its existing attachments of a bicycle that the function of lock be arranged again, has destroyed lock and has destroyed the car thigh exactly, and car still can't be ridden away.

At present, known bicycle lock structure is by lock body, and lock core and lock bridge constitute, and also has a kind of interior dress of locking bicycle handlebar not have the beam lock.The weak point of these two kinds of locks is that the former destroys easily, destroys the back car and just can ride away, and the latter can not pin wheel, and therefore, the theftproof of these two kinds of locks all has deficiency.

The purpose of this utility model provides a kind of bicycle lock, and the function of its existing bicycle thigh has the function of lock again, and pedal pins back wheels of vehicle during the lock car.As lock is destroyed, promptly destroyed the car thigh, car still can't be ridden away, thereby strengthens the anti-theft feature of bicycle.

The purpose of this utility model is achieved in that lock design is divided on the long and short two sections bicycle thigh at one that long section one end is connected with bicycle middle shaft, and the other end has lock core and lockhole, and short section is connected and lock bridge is housed with bicycle pedal is sub.With the plugging together between the two of the lock bridge on lockhole on the long section and the short section realize two sections from, close.Insert the different lock-bits and the state of lockhole with lock bridge, and realize two functions of lock and car thigh in conjunction with pedal.When the functional status of car thigh, long section combines its two parts with short section two parts by lock bridge all being inserted lockhole closely, and locks together bicycle thigh of formation.In the time will locking car, earlier the car thigh is placed the back upper place of car, with key lock is opened, extract short section it is turned over turnback in car with car pedal, and with in this pedal reeve back spoke, block trailing wheel, and then lock bridge is turned back to lockhole to locking the parking stall, at this moment extract the key car and promptly lock.When wanting by bike, again it is recovered carriage return thigh state and get final product.After this lock goes to pot, for example, cut off lock bridge, smash lock body and promptly can't recover car thigh state, make car lose the car thigh.In order to make the car thigh be difficult for pulling down, safe screw is equipped with at car axis drift bolt place.

Owing to adopt such scheme, make lock have the function of attachments of a bicycle, realized car, lock one, lock can destroy, but car can't ride away, and its theftproof of car that this lock is housed like this will be better than other known lock.

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

Fig. 1 is a lock car state of the present utility model

Fig. 2 is a car big foot state of the present utility model

In the drawings, 1. big short legs section 3. lock cores of car thigh length section 2. cars 4. lock bridges 5. central axis holes 6. car pedal connecting holes 7. drift bolts 8. safe screw 9. bonding surface grooves 10. bonding surface projectioies

In Fig. 1, long section (1) one end is connected with bicycle middle shaft with drift bolt (7) by central axis hole (5), the other end carries out plug-in type in conjunction with realizing that long and short two-part combination constitutes lock or car thigh by the lock bridge (4) on the short section (2), lock core (3) is positioned at the end that long section (1) is connected with short section (2), and it realizes pinning and unlatching to lock bridge (4).The axis hole (6) of connection car pedal is positioned on the short section (2), and safe screw (8) is positioned at drift bolt (7) side of long section (1), and it makes drift bolt be difficult for withdrawing from.Bonding surface groove (9) is positioned on the bonding surface of long section (1), and bonding surface projection (10) is positioned on the bonding surface of short section.Combine closely when forming car thigh state in long section (1) and short section (2), groove (9) and projection (10) realize chimeric, when increase intensity is used to resist to pedal to the torsion of lock bridge.
