Description

The for bicycle axial anti-riding lock

The utility model relates to bicycle lock, particularly for bicycle axial anti-riding lock.

As everyone knows, existing bicycle lock is an object with the locking wheel normally, the dead bolt of dependence lock or locking bolt or pintle hook lock or chain or lock pin remove to pin the wheel of bicycle, to prevent that bicycle is pushed away, remove or steal, because the lock part of this class lock generally is that interior shaft lock is fixed, and during locking exposed outside, can not protect to greatest extent by sled and danger destroyed, that twist off.Its barrier propterty remains further to be improved.

The purpose of this utility model is, at above-mentioned the deficiencies in the prior art, improves, and proposes also design bicycle axial anti-riding lock, pins the front fork of handle-bar with it, and it can not be freely swung and rotate, prevents the result that rides and reach bicycle.

Technical solution of the present utility model is to adopt lock tube, the lock body of packing into, be equipped with the lock core of key on the lock body, the lock core rear end is furnished with dead bolt, it is characterized in that, dead bolt adopts the screw thread dead bolt, and the screw thread dead bolt is equipped with adjustable plate, and dead bolt passes adjustable plate and cooperates with screwed hole on it.

It is characterized in that adjustable plate is joined by slide bar and lock body and connected.

It is characterized in that on the inwall between inherent adjustable plate of lock tube and the lock body boss being arranged.

It is characterized in that leaking hole is arranged on the lock tube.

It is characterized in that the locking hole that dead bolt is furnished with the obturator hernia dead bolt is located on the preceding fork shaft of handle-bar.

It is characterized in that the positive direction of locking hole and handle-bar differs 90 °, during its locking, the direction in locking hole is consistent with the axial direction of dead bolt precession.

It is characterized in that the locking hole is axisymmetric mounting hole, 180 ° of straight angles have two.

It is characterized in that having two leaking holes on the lock tube at least.

It is characterized in that the gathering sill of two lock bodies smooth sliding is arranged on the lock tube inwall.

Operating principle of the present utility model is that it is installed on bicycle tripod and the equipped position of preceding fork shaft, and the utility model just is installed when the tripod welding processing.Simultaneously before processing, become to process axisymmetrically at corresponding position during fork shaft two mounting holes as and the supporting locking hole of dead bolt of the present utility model, when using the utility model, earlier key is inserted in the keyhole of lock core, screw key drives dead bolt simultaneously after a few and advances a few, the locking hole of fork shaft before entering, before dead bolt entered in the locking hole by preceding fork shaft, this moment should be with handlebar tap direction or right half-twist left, so that dead bolt can successfully enter the locking hole.Treat that dead bolt enters in the preceding fork shaft fully, lock body is concordant with lock tube, moves handlebar with hand, after fork shaft is locked by dead bolt before confirming, key can be taken off, and whole locking work is promptly finished.

The utility model has the advantages that, initiate modern design both at home and abroad, rational in infrastructure, economical and practical, anti-push away, tamper, antitheft, pick-proof, theftproof performance is good, and this is locked in when bicycle is produced and just is installed on, and need not user's lock of spending again to purchase, be used for the locking tap, it can't be regulated, and therefore the bicycle that is locked by the utility model can't be ridden, just in case stolen, its identification is observed very convenient, is the desirable lockset of bicycle user.
