Description

Rotating rod type lock for bicycle

The utility model relates to a kind of lock that is used for motorcycle, power assist vehicle and bicycle, particularly a kind of rotating rod type lock.

In the prior art, the lock of motorcycle, power assist vehicle and for bicycle all is the ring-type lock basically, is suitable for being used for the trailing wheel of car, installs and uses not to be very convenient.

The purpose of this utility model is to provide a kind of rotating rod type lock, is applicable to the front-wheel of car, and is easy to install.

For achieving the above object, the utility model adopts following technical proposals: the same lock housing and the tapered end of including with prior art of this rotating rod type lock.It is characterized in that: a push pedal in the tapered end interlock lock housing, bull stick hinged of push pedal interlock with lock housing.During use, lock housing is fixed on the car front fork, bull stick is parallel with the wheel face of front-wheel.Lock drives the push pedal reach during car with the lock core in the key turns tapered end, 90 ° of push pedal promotion bull stick rotations, and then bull stick is inserted between the bar spoke of front-wheel and car is pinned.

Linkage structure can be designed as between tapered end and the push pedal: the lock core of tapered end is inner fixedlys connected a dial, and the dial cylindrical has a groove tooth in the downward crotch interlock push pedal.Use key rotation lock core, dial is rotated, thereby move by the moving push pedal of groove cingulum by the crotch of dial.

Push pedal when unblanking with locking is moved the final position and can be designed a stop mechanism, its structure is: fixedly connected with panel two ends in the push pedal rear portion, between push pedal and the panel spacing is arranged, during this time apart from slide lock tabs of interior plant, the slide lock tabs top edge has the reseting leaf supporting; The long waist shaped groove that aligning is arranged on push pedal and the panel has a circle lock that is fixed on the lock housing to stretch in this long waist shaped groove.During locking, the lock core of key turns tapered end, dial is rotated, the crotch of dial puts in teeth groove and will push away on the slide lock tabs and break off relations with round pin, then crotch is stirred the groove tooth and is made the push pedal reach, during to 90 ° of bull stick rotations, crotch has withdrawed from teeth groove, and slide lock tabs resets under the effect of reed elastic force and locked by round pin.When unblanking, the key opposite spin, crotch is gone up earlier the moving locking plate of sliding and is broken off relations with round pin, stirs the groove tooth then push pedal is retreated, and when bull stick returned to original position, crotch withdrawed from teeth groove, and slide lock tabs resets and is locked by round pin.

Can design a resetting-mechanism to bull stick, its structure is: the extension spring that has a bull stick to reset, one end hook are hung on the round pin on the bull stick, and the other end is hooked on the round pin in the lock housing.

Lock housing can be designed as with car front fork fixed connection structure: fixedly connected a fixture block on the base plate of lock housing, fixture block is connected with a slice intermediate plate by bolt nut.By fixture block and intermediate plate lock housing is fixed on the car front fork.

The utility model has conspicuous advantage compared with prior art: because this lock is the rotating rod type lock, can be installed in easily on the car front fork, use also very convenient.

The drawing of accompanying drawing is described as follows:
