Description

The bicycle structure lock

The utility model is a kind of and the lock bicycle integral structure, especially a kind of anti-theft lock for bicycle.

China's bicycle owning amount ranks first in the world, and the bicycle theft rate is also high always in recent years, becomes the social effects of pollution of making us hating.For preventing bicycle theft, people have designed various anti-theft vehicle locks, prize, saw, pound at cartheft in addition means such as " removing out for good and all " under, anti-theft vehicle lock is defeated one after another.Trace it to its cause, except that hit to steal car dispose of stolen goods dynamics inadequately, the major reason that lock can not the really antitheft car stealer of being be succeeded.

People are still defending tenaciously traditional lock car notion so far: promptly limit vehicle functions (travel, turn to etc.) to reach antitheft car purpose with lock.The car stealer is as destroying lock, and vehicle functions recovers immediately, and its outward appearance, structure and dispose of stolen goods and be not subjected at all to influence are so the car stealer can propagate its belief on a large scale.

The purpose of this utility model just provide a kind of can freely travel when lockset locks the parts of bicycle, and the bicycle structure that lockset is opened or just can't travel in the back that goes to pot is locked.

Bicycle structure of the present utility model lock is formed by lock core with as the bicycle structure steel tube place of lock housing, the lock core of this structure lock adopts the push-and-pull lock core, lock body is arranged in the steel pipe of bicycle structure, the inner of push-and-pull lock core is arranged in lock body, the outer end of push-and-pull lock core is arranged in the push-and-pull lock core hole on the steel pipe, the outside, middle part at the push-and-pull lock core is provided with an E shape groove, on lock body, be fixed with set pin, one end of set pin puts in the E shape groove on the push-and-pull lock core, be provided with a stage clip between push-and-pull lock core bottom in lock body and the steel pipe, by lock body, the push-and-pull lock core, it is whole that the bicycle structure steel pipe constitutes a structure lock.Establish a lock core cover on the excircle of push-and-pull lock core, a side of overlapping at lock core is provided with a jam nut, and the middle part of tie down screw is arranged in screw bolt seat, and the outer end and the spanner of tie down screw join, and the inner and the jam nut of tie down screw screw.Push-and-pull lock core, lock body are installed in the top of bicycle handle bar's steel pipe, form a structure lock integral body with the handlebar steel pipe.Push-and-pull lock core, lock body are installed in the cycle frame steel pipe, form a structure lock integral body with the vehicle frame steel pipe.During use, key is inserted in the hole of push-and-pull lock core, rotation push-and-pull lock core, because the outer wall of push-and-pull lock core is provided with E shape groove, set pin inserts again in the E shape groove, therefore the anglec of rotation of lock core is the width on " E " word base of E shape groove, when rotating to " E " word vertical edge of E shape groove, lock core can inwardly push away, set pin slides into top or middle limit by the bottom of E shape groove " E " word, and then with the push-and-pull lock core to circling round, this moment, this push-and-pull lock core was arranged in the structured steel pipe of bicycle, and did not lock mutually, between the perpendicular handle and cross handle as if the handlebar that this lock is positioned at bicycle, then the perpendicular steel pipe of bicycle handle bar and horizontal steel pipe are unfixing, free to rotate, so bicycle just can't be ridden under the situation that can't use handlebar.When the push-and-pull lock core is pulled out locking from another push-and-pull lock core hole after, because the angle between handlebar and the vehicle body is not 90 °, so also inconvenient cycling.When with key the push-and-pull lock core being rotated and withdrawing from the hole that is stuck in steel pipe, lock core and steel pipe locking, the perpendicular steel pipe of bicycle and the locking of horizontal steel pipe, handlebar just can artificially be controlled with handlebar is the same normally and use this moment.If this lock is positioned on the vehicle frame of bicycle, fixing or rotated after certain direction fixingly again between the steel pipe of vehicle frame, make not in-line of vehicle frame, bicycle can't travel too.

The invention has the advantages that:

Adopt the reverse thinking mode, change the outmoded conventions that traditional lock limits vehicle ', turns to function, courageously lockset and a certain block construction of vehicle are made up in design.When lockset locks these parts, but vehicle cruising (turning to); Otherwise the not locked or destroyed forfeiture effect of lockset of these parts then can't cruising (turning to).Sled is pounded lockset and will be caused vehicle can't dispose of stolen goods just as scraped car, makes robber's car become meaningless.

This structure lock is installed in the different parts of vehicle, can become multi-form anti-theft bicycle: as vehicle frame lock, handlebar lock, saddle lock etc.Be example with the vehicle frame lock now, when lockset was in " work " state, vehicle frame was locked into integral body by lockset, can work safely and reliably; When lockset was in " antitheft " state, the part vehicle frame into a bent shape or free to rotate can't cruising (turning to)." work ", " antitheft " two states all need to realize by lockset.Lockset can be hidden in vehicle frame inside, and purpose made cross recess lock core has anti-drilling function, and the key recurrence rate only is ten thousand/, it is atomic to throw robber's car possibility that key unblanks.As destroy lockset, and not only can't recover the vehicle frame function, car load will be scrapped, more can't use or dispose of stolen goods.

In like manner, the handlebar lock is combined lockset and handlebar, and the saddle lock is combined lockset and saddle.When lockset was in " work " state, handlebar, saddle had normal function; When being in " antitheft " state, handlebar, saddle forfeiture normal function destroy lockset car load will be scrapped, and make the car stealer keep someone at a respectful distance.

The utility model structure lock applicability extensively, does not influence vehicle appearance, safe and reliable, easy to use, good confidentiality.During produce in factory design, technology are changed slightly, only need increase a small amount of cost and promptly can be made into new ideas bicycle with real antitheft meaning.
