Abstract

The utility model provides a directional locking device for bicycles. The antitheft goal is attained by fixedly locking the steering mechanism of a bicycle with the bicycle and the bicycle frame deflecting an angle. The locking device comprises a lock body, a lock core, the lock body of a lock pin, and a lock sheet with a lock hole, wherein, an eccentric rotary mechanism which can drive the lock pin to make straight-line movement comprises the end of the lock core and the lock pin; the lock body and the lock sheet with a lock hole are respectively fixedly connected with the bicycle frame at the front end of the bicycle and a corresponding position on the front fork of the bicycle. When the directional locking device for bicycles is used, only a key is inserted into the directional locking device for bicycles to rotate the lock core, and the lock pin is inserted into the lock hole so as to lock the steering mechanism of a bicycle. Thus the bicycle can not be ridden and pushed.

Description

Directional retaining mechanism of bike

The utility model relates to a kind of latching device, and the directed latching device of bicycle particularly is by locking the motion that limits bicycle to the orientation of turning of bicycle mechanism.

The present burglar-proof measure of bicycle normally additional one is locked pincer on bicycle, and ring lock or steel rope lock mechanically limit the running of cycle wheel.Use these locks that the integral structure of bicycle is lacked perfection, and the installation and the locking operation of lock all make troubles to the car user.

Bicycle is in riding or carrying out, and the end user will come left-right rotation bicycle front-wheel by handlebar, and turning of bicycle is turned round, and with this balance that keeps car, makes bicycle continue to advance under state of equilibrium.The left-right rotation that does not have front-wheel, bicycle have just lost balance, can not turn to.The directed latching device of a kind of bicycle that the utility model provides be exactly with the foresteerage gear of bicycle with angle of vehicle frame deflection after locked, make front-wheel admittedly extremely an angle, can not left-right rotation, bicycle can not be ridden also can't carry out, to reach thief-proof purpose.

The utility model is finished like this: the directed latching device of bicycle is made up of lock body that comprises lock body, lock core, lock pin and the locking plate that has a lockhole.Insert key rotation lock core, can make lock pin insert or withdraw from lockhole.The steering hardware of bicycle is made up of handlebar, front fork and front-wheel.Lock body and the locking plate opposite position on bicycle front end vehicle frame and bicycle front fork that is fixedly connected respectively.Be that lock body can be fixed on the bicycle front end vehicle frame, also can be fixed on the front fork that corresponding with the lock body position, the locking plate that has lockhole can be fixed on the front fork, also can be fixed on the front end vehicle frame.At least 1 of lockhole on the locking plate can be selected the deflection angle of front-wheel in order to make bicycle when locking, the lockhole on the locking plate also can be provided with a plurality of.Lock core is terminal forms the eccentric rotary mechanism that can drive the lock pin moving linearly with lock pin, and promptly the end at lock core has an eccentric protruding pin, and with matching is a U-shaped breach on the lock pin.The free end of lock pin has a pilot hole.Lock core rotates, and the eccentric protruding pin in lock pin U-shaped breach is just done circular motion, drives lock pin and makes upper and lower straight-line motion along pilot hole, makes lock pin insert or withdraw from lockhole.

The directed latching device of the bicycle that the utility model provides, in the bicycle production process, just permanently settle onboard, make bicycle compact overall structure, reasonable, in use as long as with angle of handlebar rotation, rotational lock core makes lock pin aim at lockhole and inserts, just locked bicycle, therefore easy to operate, again owing to lock body and the locking plate that has lockhole are fixedly connected on car body, auto theft person has only this being fixedly connected of destruction, and damage the car body of connection place simultaneously, and just can free locking mechanism, therefore have lock mode novelty, reliable characteristics.

Below in conjunction with the accompanying drawings structure of the present utility model is further described with embodiment:

Fig. 1 is the constructional drawing that lock body is installed in the preceding pipe place of vehicle frame.

Fig. 2 is Fig. 1 structure (lock is opened shape) A-A amplification profile.

Fig. 3 is the section-drawing of Fig. 2 structure locking lock shape.

Fig. 4 is that lock body is installed in the constructional drawing in the frame-front fork shoulder.

Fig. 5 is that lock body is installed in the constructional drawing between preceding pipe of vehicle frame and down tube.

Fig. 6 is that lock body is installed in the constructional drawing on the front fork shoulder grafting plate.

Directed latching device shown in Figure 1 is the tubulose lock housing 2 that pipe 1 lower adaptor place can be installed lock body with one of welding method crosswise fixed before cycle frame.The lock body that comprises lock body 6, lock core 7, lock pin 4 is packed into after this lock housing 2, and lock pin 4 is downward, as Fig. 2, shown in Figure 3 on lock body 6 the lock pin position one pin-and-hole is arranged, what join with pin-and-hole on the lock housing 2 is a pilot hole that cooperates with lock pin 4.Make locking plate with front fork shoulder 3, establish lockhole thereon.U-shaped breach on the eccentric protruding pin 8 of lock core 7 ends and lock pin one end has been formed eccentric rotary mechanism, during use key inserted lock core 7 rotational lock cores, eccentric protruding pin 8 just clockwise rotates, and stretches out lock body by the drive of the U-shaped breach on the lock pin 4 lock pin, and front fork 5 is rotated an angle, make lock pin 4 insert lockhole, front fork 5 is promptly locked, can not rotate, otherwise, lock core 7 rotates counterclockwise, and lock pin 4 just withdraws from lockhole.

Fig. 4 is on the bicycle of pipe shoulder formula front fork, utilizes the front fork of pipe shoulder formula to take on the 3 endoporus lock body of packing into, goes out the implantation site at lock pin 4 and connects an orienting lug 10, and the locking plate 9 that has a lockhole is fixedly welded on pipe 1 lower adaptor place before the vehicle frame.Lockhole on the locking plate 9 has a plurality of (not shown)s.

Directional lock device shown in Fig. 5 is applicable to the bicycle of single-beam vehicle frame, brace panel 12 of 11 welding of pipe under pipe 1 and the single-beam before vehicle frame, to strengthen the intensity of vehicle frame, utilize this brace panel to make lock housing simultaneously, lock body is packed into wherein, lock pin 4 is settled downwards, has the locking plate 13 in a hole with lock to be welded on the front fork shoulder 3 in the corresponding position of lock pin.

Shown in Figure 6 is fishplate bar 15 of welding on bicycle front fork shoulder 3, the lock housing 14 of burn-oning on the fishplate bar, lock body is packed after the lock housing lock pin 4 into upwards, the locking plate 16 that has a lockhole be welded on the corresponding down tube 11 in lock pin 4 positions and vehicle frame before on the joint of pipe 1.

Claims (2)

1, the directed latching device of bicycle, form by lock body that comprises lock body, lock core, lock pin and the locking plate that has a lockhole, insert key rotation lock core, can make lock pin insert or withdraw from lockhole, it is characterized in that be fixedly connected respectively opposite position on bicycle front end vehicle frame and bicycle front fork of lock body and locking plate, lock core is terminal forms the eccentric rotary mechanism that can drive the lock pin moving linearly with lock pin.

2, directed latching device according to claim 1 is characterized in that eccentric rotary mechanism is that the lock core end has an eccentric protruding pin, and with matching is a U-shaped breach on the lock pin.
