Abstract

The utility model discloses an overturn type anti-theft lock for a vehicle. The anti-theft lock is structurally characterized in that a lock body and a locking bar support are correspondingly fixed on a vehicle fork, an overturn device on the locking bar support comprises an overturning rod, a torsion spring and a guiding sleeve, a locking bar guiding sleeve is fixed at the end of the overturning rod sleeved with the torsion spring, and a guiding claw and a clipping plate are arranged at the end of the guiding sleeve; and a slideable locking bar, the effective length of which is slightly larger than the thickness of the vehicle spoke and on which a return spring is sleeved is inserted in the guiding sleeve. When the vehicle is locked, the locking bar is shifted horizontally and pushed to the lock body, so that the end of the locking bar is inserted into the lock body to lock the vehicle, and the clipping plate clips the locking bar support and limits the rotation of the overturn device; when the vehicle is unlocked, the locking bar is separated from the lock body and returns back automatically, the clipping plate returns, and the locking bar is automatically overturned to the vertical position under the function of the torsion spring. Iron scissors can not be inserted into the lock, thereby preventing the locking bar from being sheared off, and having good anti-theft effect; and the locking bar returns and is overturned automatically, which is very convenient for use. The anti-theft lock is mainly used for a motorcycle, and can also be used for a bicycle and a tricycle.

Description

Convertible anti-theft lock for vehicle

Current, people ride the used inserted link lock of motorcycle, bicycle, the tricycle of usefulness and mainly are made of lock, U-shape sword iron, and lock is fixed on a certain position of the front fork or the vehicle frame of car, and locking bar passes spoke and inserts that in the lock wheel can not to be rotated lock tight.Though the lock of this kind structure is simple in structure, U-shape sword iron exposes in the spoke outside, and thief is easy to iron shears locking bar be cut off car is stolen; Lock car in addition, Shi Deyi the hand of unblanking unblanked, a hand-lifting locking bar, uses inconvenient.

Three, summary of the invention

In order to solve the deficiencies in the prior art, the purpose of this utility model provides a kind of easy to use and antitheft convertible anti-theft lock for vehicle.

The purpose of this utility model is achieved in that this theftproof lock mainly is made up of lock body, locking bar support, locking bar and turning device; The corresponding car that is fixed on of lock body and locking bar support is stuck, and a side of locking bar support has turning device, and turning device is made of turning rod, torsion spring and fairlead; The Kong Houqi end that the centre is with the turning rod insertion locking bar support of torsion spring is fixed with the locking bar fairlead, the end of fairlead is provided with guide grab, the tail end of guide grab has square hole, be inserted with the clamp of the control turning device rotation that can slide in square hole in the square hole, there is the stairstepping draw-in groove that can block clamp lock body support and corresponding section, clamp end; Be inserted with effective length in the trepanning of fairlead and slightly be wider than the slidably locking bar of rung bar rugosity, the locking bar that is with return spring has dop near lock body end end, and the other end is fixed with spring base, and there is the gathering sill by the guide grab location at the middle part.During the lock car, move locking bar to horizontal level, pushing spring base makes locking bar insert in the lockhole of lock body to slide its end of lock body direction, dop blocks lock tight by the snap in the lock body, press clamp downwards when spring base moves to certain position simultaneously, clamp blocks the rotation that the locking bar support has limited turning device; Twisting key when unblanking, dop breaks away from the snap locking bar and returns automatically, and clamp end return breaks away from support automatically, makes locking bar be turned to the upright position automatically under the effect of torsion spring.

The utility model can't insert iron shears and can prevent that locking bar from being cut off because the effective length of locking bar slightly is wider than rung bar rugosity, has played anti-theft effect; Because the self-return of locking bar and the effect of turning device, just can unblank and dispense with a hand pull out, the trouble of latch lever, so the use special formula is just.This theftproof lock is mainly used in motorcycle, also can be used for bicycle, tricycle etc. and plants vehicle.
