Description

The coordinated type anti-theft lock for bicycle

Technical field

The utility model relates to a kind of anti-theft column lock, or rather, relates to a kind of anti-theft lock for bicycle.

Background technology

Bicycle is a running vehicle the most frequently used in people's daily life, because it is simple in structure, easy to use, cheap, rides for a long time and can also improve the health, and therefore is subjected to liking of people from all walks of life deeply.Existing bicycle lock and vehicle body all are independently, and general lock is mounted near the wheel of body tail, can only pin trailing wheel, bring opportunity so just for row robber person.The characteristics that row robber person can utilize the bicycle front-wheel to rotate naturally are hooked on the back shelf between waist, easily bicycle are stolen.And this lock also is easy to be pried open the theftproof performance extreme difference.For the sake of security, the cyclist not only locks front-wheel but also lock trailing wheel with regard to handy two locks, and such two locks must be equipped with two keys, every day switch lock for several times or tens of times, be pretty troublesome really.

Summary of the invention

Task of the present utility model provides a kind of coordinated type anti-theft lock for bicycle.This lock is installed in that not only theftproof performance is strong in the yi word pattern vehicle body, and can effectively reduce the trouble that frequent switch lock brings, and remedies the deficiency that existing bicycle lock exists.

Task of the present utility model is realized by following mode: it comprises built-in lock, sleeve, outer tube, spring, pin, backguy, minor axis, be provided with built-in lock at the yi word pattern vehicle body, establish link mechanism in the vehicle body, the connector of link mechanism is meshed lock snap close after the backguy end of link gear connects respectively with the snap close of built-in lock and the lock core of preceding lock.Described link mechanism is to connect a movable plate through minor axis, and hinged one an of end of movable plate is respectively equipped with and the snap close of built-in lock and the corresponding identical interface of lock core of preceding lock, and the other end is provided with the leverage of the connector composition of backguy.Lock is by being with spring and can constituting at the inside and outside mobile lock core of sleeve before described.Described back lock is to establish the depression breach by cylindricality pipe link one end, remainder is established axial hole, one spring is arranged in the hole, establish the lock core that the bar groove that communicates with the hole is formed along the hole, be provided with in the lock core outside of corresponding bar groove to insert the pin bonded assembly sleeve pipe in the hole and may be stuck in snap close in the lock core depression breach and combine formation through the bar groove.

This utility model is arranged on the yi word pattern interior of body, and is very hidden, survivable, and it utilizes built-in lock, link mechanism that forward and backward lock is ingenious at coordinated control, makes it have extremely strong theftproof performance, is difficult for stolen.On the one hand can reduce the stolen economic loss of bringing, and pinning front fork, trailing wheel only use a key, bring great convenience to the cyclist.Simultaneously can make the stolen incident of bicycle of frequent generation controlled again, stablize civil order.This utility model has also that compact conformation is reasonable, stable and reliable for performance, good looking appearance is generous, economical and practical characteristics such as durable.

The specific embodiment

Coordinated type anti-theft lock for bicycle in the accompanying drawing is a kind of disguised lock of design and installation in the yi word pattern vehicle body.Fixing built-in lock 2 on yi word pattern vehicle body 1 at first, corresponding shaft core position is established radial direction through hole along the inside and outside wall of outer tube 3, car fork sleeve pipe 4 in vehicle body 1, and corresponding through hole is provided with a preceding lock that is with spring 5 and can forms at the sleeve 6 inside and outside lock cores that move 7.Before lock pin 7 be that top is that circular arc, end have an annular groove and boss, the surface is provided with that the pipe link of limiting block constitutes.Establish minor axis 8 in vehicle body 1 middle part, minor axis 8 connects movable plates, and movable plate one end connects a connector 10 that is provided with the lock core 7 corresponding identical interfaces of the snap close 9 of built-in lock 2 and preceding lock through hinge, and minor axis 8 other ends are provided with the link mechanism that a backguy 11 is formed.Backguy 11 is connected with the back lock snap close 13 that is provided with spring 12, and built-in lock 2 is fixed on vehicle body 1 middle part, and the snap close 9 of built-in lock 2 and lock core 7 ends of preceding lock are meshed with cooresponding identical interface on its connector 10 of link mechanism respectively.The back lock is set at the rear portion of this vehicle body 1, the back lock is individual by establish depression breach 14 at cylindricality pipe link one end, remainder is established axis hole, one spring 15 is arranged in the axis hole, establish the lock core 17 that the bar groove 16 that communicates with the hole is formed along the hole, be provided with in lock core 17 outsides of corresponding bar groove 16 to insert the pin 18 bonded assembly sleeve pipes 19 in the hole and may be stuck in snap close 13 in the depression breach 14 on the lock core 17 and combine formation through bar groove 16.Sleeve pipe 19 1 ends are provided with screw thread, are connected and fixed through this screw thread and body tail.Back lock snap close 13 should slide by set slideway in vehicle body.

During the lock car, key 20 is inserted built-in lock 2 and rotation, the identical interface that built-in lock snap close 9 breaks away from its connector 10 of link mechanism, preceding lock spring 5 releases energy, and lock core 7 is pushed in the radial direction through hole, pins front vehicle fork.Meanwhile, the snap close 13 of back lock also slides to lock pin 17 edges, back under link mechanism and spring 12 effects, the rear lock core 17 usefulness hands that expose part outside vehicle body 1 this moment inwardly push away, lock core 17 hole inner springs 15 pressurizeds, lock snap close 13 places make it and its engagement chucking after the depression breach 14 on the lock core 17 is pulled to.Just trailing wheel is pinned.

When unblanking, will insert built-in lock 2 and contrarotation by key 20, the interface engagement coincide on built-in lock snap close 9 and its connector 10 of link mechanism, connector 10 pulls back the lock core 7 of preceding lock, open preceding lock because effect spring 5 pressurizeds of limiting block are extracted the top of preceding lock pin 7 out in radial direction through hole this moment.Under the interlock effect of link mechanism, its terminal backguy 11 bonded assembly rear catch 13 break away from the depression breach 14 on the rear lock core 17 and the back lock are opened.It is extremely convenient to use.
