Abstract
The utility model relates to a two-wheel bicycle, in particular to a directional lock anti-prizing device for bicycle front wheel. Beside the one end surface of the lock core is exposed, other mechanisms are totally installed in the inner of the steel tube of the bicycle; so the problem of the easy prizing of the bicycle lock can be solved, and the difficulty of the bicycle pilfering is increased. When the utility model is installed, the production technique of the original bicycle is not need to be changed. The utility model has simple production, safe utilization and reliable anti-theft function. The picture 1 is a key, the picture 3 is a front fork longitudinal shoulder, and the picture 20 is a crossbeam.
Description
The utility model relates to a kind of two-wheel car, particularly the device of bicycle front-wheel orientation lock.
The lock that existing bicycle theft-prevention uses is mounted on the back vent of vehicle seat bottom, is used for pinning the trailing wheel of bicycle, and outside this bicycle lock all was exposed to, the bicycle lock shell all can destroy lock housing with thick iron sheet manufacturing, the stealer of generally holding instrument, and lock was lost efficacy.For addressing this problem, the common practice is to adopt the iron sheet of thickening to make lock housing, so still can not prevent burglar's behavior effectively.
The directed anti-joyride device of the bicycle front-wheel that Chinese patent application GG86201783 proposes can solve the problem that lock housing is prized, and has increased the difficulty that pushed away away bicycle before lock lost efficacy, but outside this device lock pin part still is exposed to, can not prevent burglar's picking lock effectively.
The purpose of this utility model is the device that the directed pick-proof lock of a kind of bicycle front-wheel will be provided, and it can prevent effectively that the burglar from stealing car, and particularly burglar's picking lock is stolen car.
The purpose of this utility model is to realize like this, lock core body (2) is fixed in the endoporus of the horizontal shoulder of bicycle front fork (3), be installed in lock body (16) and transmission component (9) in the endoporus of front fork vertical pivot (17) together to (15), during the lock car, make front-wheel turn over certain angle earlier, driving transmission component by key (1) by lock core (4), dead bolt (5) inserts in the auxiliary hole (19) of bicycle crossbeam pin (11), make bicycle front fork and bicycle crossbeam form a fixing angle, the burglar can't push away away this bicycle.
The utility model is owing to lock core body (2) and front cross shoulder (3) are fixed as one, lock body (16) and member (9) are installed in the inside of bicycle to (15), only there is an end face of lock core (4) and lock core body (2) to expose, if do not destroy bicycle, even the burglar holds instrument, also be difficult to picking lock, compare with lock back wheel mode, front-wheel orientation lock mode has increased the difficulty of surreptitiously pushing the machine.
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is the constructional drawing of an embodiment of the present utility model.
Fig. 3 is the constructional drawing of another most preferred embodiment of the present utility model.
Referring to Fig. 1, this device does not change the outward appearance of original bicycle, after key (1) injects the lock core be contained in the front cross shoulder endoporus, can open, latching operation.
Referring to Fig. 2, lock core body (2) is fixed as one with front cross shoulder (3), key can make lock core (4) and dead bolt (5) move the distance of a pellet shot from a slingshot along axis direction in lock core (2), after lock core (4) is compressed into, take off key, lock core just can not move, and at this moment lever (10) makes pin (11) withdraw from auxiliary hole (19) on the crossbeam, and lock is opened; During the lock car, after advancing lock core (4) under the key, spring (9) returns lever (10), pin (11) puts in the hole (19), and dead bolt (5) is ejected with lock core (4), take off key, lock core (4) is at lock core body (2) internal fixation, and at this moment front fork (17) is fixed as certain orientation with crossbeam (20).Embodiment among Fig. 2 can be installed as 0-30 ° with the angle between front cross shoulder (3) and crossbeam (20).
Referring to Fig. 3, lock core body (2) is identical with fixed form and Fig. 2 of horizontal shoulder (3), key can make lock core rotate 90 ° in lock core body, lock core drives dead bolt can make little axle (12) rotate, little axle (12) rotates fork (13) is rotated around axle (14), and shift fork (13) can only have two stable stop places under the effect of spring (9), make pin (11) put in (19) or introduction hole (19), the purpose that reaches lock and open.After locking, front fork and crossbeam are fixed as certain orientation.Little axle (12) can not rotate in same plane with shift fork (13).Present embodiment can be installed as the angle between front cross shoulder (3) and crossbeam (20) 60 °-90 °.Spring perch (21) on the fork (13) departs from a side of shift fork axis, makes elastic force after unblanking greater than the elastic force after locking, and prevents et out of order in the back bicycle walking process of unblanking.Because lock core is stuck in lock core body, shift fork (13) and pin (11) can not return unlocking condition behind the lock car.
The device of the directed pick-proof lock of bicycle front-wheel provided by the utility model uses safety, and is antitheft reliable. This device is installed, is not needed to change the production technology of former bicycle, only need in the bicycle front cross shoulder, to bore respectively an aperture (8) and (18) in the hole He on the vertical pivot, just this device can be installed on the car front fork.
Claims (4)
