Abstract
The utility model relates to a mini bicycle which is easy to adopt a simple folding mechanism. An upper pipe and a front pipe of the frame of the bicycle have the two axial lines intercrossing with each other with a certain angle within the range from 90 to 95 DEG. The back wheel and the front wheel have a certain radius proportion within the range from 1: 0.5 to 1: 0.7. The utility model has the outstanding advantages of short frame, smaller front wheel and the achievement of a portable folding mini bicycle through the simple folding mechanism that the handles are folded on one side, the saddle is moved downwards and the pedals are folded.
Description
The utility model belongs to bicycle, especially relates to a kind of miniature bike of being convenient to adopt simple fold mechanism.
Because the vehicle frame shape of existing miniature bike is confined to traditional rhombus or the vehicle frame front side is single, double tubular, therefore portable foldable structure is inevitable at first to be the folding of vehicle frame, not only its folding means is more and make complex structure, also has the unfavorable defective of integral thickness after folding.In addition, the existing forward and backward wheel of miniature bike is isometrical design, also is the at first major reason of folding stand of portable folding structure.
The purpose of this utility model provides a kind of miniature bike of being convenient to adopt simple foldable structure.
Above-mentioned purpose is achieved through the following technical solutions: the two axial lines angle of intersection that goes up pipe and preceding pipe of vehicle frame is the 90-95 degree, and the radius ratio of trailing wheel rim and front-wheel rim is 1: 0.5-0.65.
Said going up managed the seat pipe that its rear end fixedly has the support saddle of independent open lower port, and the upper end of inclined tube fixes with the seat pipe behind the vehicle frame.
Said going up between its front portion of pipe and the frame five-through axle sleeve is provided with support tube.
Its length of pipe is greater than front vehicle fork bow-shaped section length before said.
Advantage of the present utility model is: vehicle frame length is short and front-wheel is less, therefore can adopt easily to the side handlebar of turning back and can realize the portable folding miniature bike to pipe, the simple foldable structure that moves down saddle and folding pedals.
Below in conjunction with embodiment and description of drawings the utility model thereof
Accompanying drawing 1 example structure scheme drawing
Embodiment as shown in the figure, to intersect angle be 90 degree for go up pipe 2 and preceding pipe 4 two axial lines of vehicle frame, the rim radius R=175mm of trailing wheel 7, the rim radius R=100mm of front-wheel 5, about 1: 0.57 of the ratio of trailing wheel and front-wheel radius.Seat pipe 9 is fixed in pipe 2 rear ends, and have independently, open lower port so that saddle is displaced downwardly to lowest order or suitable height by its standpipe 10, the shank of the key that standpipe is managed 9 upper port by seat locks.The front end and the frame five-through shaft room of accompanying drawing 1 top tube 2 are welded with support tube 3, and it matches with the rear supporting tube that five-way shaft room tradition is provided with last pipe 2 rear ends, can effectively strengthen frame strength.Pipe 4 highly is 240mm before the vehicle frame of present embodiment, and greater than the 170mm height of front vehicle fork bow-shaped section 6, this design is to satisfy path front vehicle wheel needs.
The handlebar of present embodiment promptly is provided with its pipe 1 of transverse tube and makes it to realize rolling over the connecting device that turns over to a side.
Claims (4)
1, miniature bike, by vehicle frame, transverse tube, pipe, front vehicle fork, saddle and standpipe, front and back wheel is formed, and it is characterized in that: it is the 90-95 degree that the two axial lines that goes up pipe and preceding pipe of vehicle frame intersects angle, and the radius ratio of trailing wheel rim and front-wheel rim is 1: 0.5-0.65.
2, bicycle as claimed in claim 1 is characterized in that: the said pipe of going up, its rear end fixedly have the seat pipe of the support saddle of independent open lower port, and the upper end of inclined tube fixes with the seat pipe behind the vehicle frame.
