Description
The utility model relates to bicycle, relates in particular to a kind of collapsible box-type bike that is convenient for carrying.
Existing folding bicycle integral body is heavier, and travelling is carried still inconvenient.CN2039296U discloses a kind of box-type bike, and this Collapsible bicycle is equipped with a tank tower on trailing wheel, and the time spent can not fold car and be loaded in this case, is convenient to travel outdoors and carries, but still exist the car load degree of utilization not high, folding difficulty.
The utility model purpose is to overcome the deficiencies in the prior art, and a kind of car load degree of utilization height is provided, folding convenient, and outward appearance is good, the box-type folding bicycle of being more convenient for carrying.
The scheme that the utility model purpose realizes is that bicycle is to adopt " U " shape vehicle body frame that is connected into by folding rotating shaft by two joints, and the leading portion vehicle body can be done 90 ° of rotations along rotating shaft, makes front-wheel and headstock car fork divide corresponding recovery to draw close after the rotation.Trailing wheel is connected on the wheelset axle and can receives forward by the car fork and leans on, and car fork other end is connected to strut and is fixed on the vehicle body by strut, makes the trailing wheel location.Specifically can be one of rear vehicle fork to be turned be fixed on the vehicle body wheelset axle in the heart, the other end is pitched into rear axis and is fixed, one of rear wheel of rear vehicle fork connection upwards has the arc convex of trough of belt and is connected with trailing wheel stretching, extension strut with the blue support of folding type by the screw rod that penetrates in the groove, and screw rod can move up and down in groove; Trailing wheel two stretches the strut terminations and is connected to a snap ring alives that is inserted in vehicle body, and the horizontal stripe of giving prominence on the snap ring of living snaps in the hole clipping internal fixation of lifting card, and the lifting cartoon is crossed screw retention on pinion stand.When the lifting card being rotated 90 ° when horizontal stripe on the snap ring alive being taken off collude, down promote trailing wheel forward, the snap ring of living this moment moves down along vehicle body, and trailing wheel is received by closing up behind body bottom section to front-wheel, and the horizontal stripe on the snap ring of will living again snaps in positioning and fixing in the corresponding hole clipping of lifting card.Drive system adopts secondary drive, promptly drives driven wheel by axis, by driven wheel direct drive train of gears, is driven the flywheel on the trailing wheel and drives trailing wheel by chain by flywheel on the train of gears again and rotate.The utility model handlebar width equals to close up back bicycle head shrinking connecting-rod and sits width between the saddle shrinking connecting-rod, and handlebar can be inserted in and be fixed on two shrinking connecting-rods that have the elasticity card.
The scheme that the utility model is further realized, be that a movable detachable casing respectively is housed behind the car front truck, the rear box width can pack into after the folding bicycle and in the bottom cardan wheel is housed, preceding casing can cover that the bicycle that is inserted in after the folding makes it and the rear box that has a snap close fuses.
After the utility model adopts such scheme, the mounting or dismounting of the box-type folding bicycle of manufacturing freely, small and exquisite spirit dragon, light generous, it is many to carry the loan amount, need not any instrument, promptly dismantled and assembled in several minutes.Promptly become suitcase type tourism waggon after folding vanning, convenient going away carried.
