Description
The utility model relates to a kind of multifunction bicycle, can solve the short-distance transportation problem of single travelling, rest and a small amount of goods.
Bicycle is as a kind of simple and practical single vehicle, from the popular welcome that just is subjected to people that day of its birth.At present, the bicycle of various models, various uses is a feast for the eyes, bring a lot of convenience to daily life, along with the raising of people's living standard and the change of economic condition, people are more and more higher to the requirement of bicycle, and it is comfortable light not only to require it to ride, and also require it attractive and durable, one-object-many-purposes becomes people's multi-purpose tool during the journey.
The bicycle function singleness of using is carried inconvenience at present, can not be well compatible with vehicle such as automobile, trains, limited its field of application.Therefore, people need later-model, portable, multifunction bicycle to satisfy higher needs.
The purpose of this utility model is for people provide a kind of multifunction bicycle, and it has three functions: i.e. bicycle, seat and hand barrow, characteristics: collapsible, easy to carry and store.
The utility model is achieved in that on two vertical edges of rectangle car beam, but has two groups to be enclosed within the polygon supports that omnidirectional rotates on the vertical edges, supports front-wheel and trailing wheel respectively.Upper and lower port at the front and back wheel rack sleeve is welded with four engagement pads respectively, forms four pairs of location engagement pads with four engagement pads of last underbeam.Fastening Luo bolt is arranged at the underbeam bottom, is welded with axis mounting pipe and saddle connection pipe on rear wheel support, and saddle connection pipe upper end is welded with clothes hanger and trailing wheel is tiltedly pitched shared connection pipe, and the clothes hanger afterbody is equipped with the double freedom castor.On the front-wheel support, be welded with the front fork mounting pipe, difunctional level fork is equipped with in the front fork lower end, and horizontal fork-tail portion is welded with a pair of locating dowel pin.Front-wheel support vertical pipes bottom is welded with locating plate, and the knock hole on the locating plate is corresponding with locating dowel pin.The seat cushion net is equipped with in the centre of rectangle car beam.
When current rear wheel support and rectangle car fine strain of millet are in alignment, tighten fixed bolt, the difunctional horizontal bolt nail of front-wheel is transferred to from knock hole, front-wheel can freely rotate under handlebar control, and promptly be ordinary bicycle this moment.Unclamp fastening Luo bolt, the front and back wheel support rotates the fastening Luo bolt in 90 degree backs inwards along vertical beam, and the difunctional horizontal bolt nail of front-wheel is inserted in the knock hole, unclamp bolt core Luo, extract out in the socket at handlebar insertion rectangle car beam entablatrance middle part, fastening core Luo bolt, promptly be hand barrow or seat this moment.If put between two wheels after will handlebar extracting out, full car promptly becomes the folded state of minimum volume, carries in the portable case and bag of can packing into to get on the bus or deposit.
Owing to adopted such scheme, realized one-object-many-purposes and make it become whole carry-on instrument during the journey.Its structure, productive costs and ordinary bicycle are suitable substantially.
Below in conjunction with drawings and Examples the utility model is further specified.
