Background technology
Parking of bicycle, no matter still Anywhere in the sub-district, be one all because of lock and bicycle, losing of bicycle often taken place, cause certain loss and bring a lot of troubles to people, people urgently wish to have a kind of device that bicycle rack (canopy) and bicycle can be locked together, the problem that Jie certainly loses car.
Summary of the invention
The purpose of this utility model provides a kind of blocking device of bicycle rack, with the device that bicycle rack and bicycle lock together, can prevent that bicycle from losing, and can satisfy bicycle again and put neatly, beautifies the environment.
The utility model is achieved in that a kind of blocking device of bicycle rack, by last steel pipe, and following steel pipe, support tube, column constitutes.Last steel pipe, following steel pipe all is fixed on the column, and wherein support tube is contained between steel pipe and the following steel pipe, it is characterized in that being equiped with on the steel pipe on the support tube bonded assembly a plurality of cores, and the core stationkeeping is on the position of support tube and last steel pipe junction.
Be equipped with on this time steel pipe and the corresponding one by one pin of last steel pipe core.
Core comprises eccentric wheel, backguy, and the backguy fixed mount is equipped with eccentric wheel on the core center shaft, offer the backguy groove on the eccentric periphery, one end of backguy is fixed in the backguy groove with jackscrew, and the other end of this backguy passes support tube, is connected with linkage pull rod in the pin on the following steel pipe.
Pin comprises linkage pull rod, linkage pull rod guiding, insurance shift fork, dead bolt, thimble, dead bolt guide plate.Backguy in the pin is connected with linkage pull rod, the linkage pull rod setting is given in the linkage pull rod guiding, dead bolt, the insurance shift fork, thimble all inserts in the corresponding axle, and an end of axle is welded on the base plate of pin, and the linkage pull rod guiding is welded on the left side plate respectively, the insurance shift fork all is equipped with spring on the thimble.
When depositing bicycle, the bicycle front-wheel is pushed in the pin breach, makes in the lock and move behind the thimble, drive the dead bolt return, owing to the effect of spring, the insurance shift fork withstands dead bolt simultaneously, and the dead bolt closure is pinned the bicycle front-wheel.
When picking up the car, key is inserted core, key rotates in the hole, makes the eccentric wheel rotation, moves thereby drive backguy, and the other end of backguy passes in the pin that enters down in the support tube on the steel pipe and is connected with linkage pull rod.When backguy spurred main linkage pull rod and moves right, fixing interlock sheet then clockwise rotated, and made the moving pull bar of duplicate invoice to left movement, thereby the linkage pull rod two ends are moved to the center, and the insurance shift fork is rotated to an angle, dead bolt is subjected to action of the spring, outwards open, this moment, bicycle can take out.So the blocking device of this bicycle rack, the certainly problem of losing of bicycle can be situated between.
