Description
Technical field:
The utility model relates to a kind of bicycle.Particularly relate to the collapsible speeding-up bike of a kind of hand-held design.Belong to the traffic appliance technical field.
Background technology:
Before the utility model was made, existing Folding Bicycle generally was made up of folding stand part, wheel partial sum power pack section.Its power pack section is made up of stretcher, pedal spindle, planetary wheel and messenger chain.Rotate stretcher, drive to planetary wheel by pedal spindle, to sun gear, sun gear is transferred to messenger chain by sleeve by planetary gear ring engaged transmission, drives the trailing wheel rotation, moves ahead to drive bicycle.Because its power pack section employing planetary wheel reaches the effect of speedup, so its power pack section parts cost is higher.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of light collapsible speedup that can reduce power pack section parts cost under the prerequisite that reaches same speedup effect voluntarily.
The purpose of this utility model is achieved in that the collapsible speeding-up bike of a kind of hand-held design, comprise folding stand, saddle, front-wheel, trailing wheel and power pack section, described folding stand comprises handlebar, preceding bar, king-rod, back bar, front support rod, back support rod, front wheel carrier and trailing wheel jaw, preceding bar upper end is middle hinged with handlebar, the lower end links to each other with front wheel carrier, the king-rod lower end is hinged with front wheel carrier and back bar front end respectively, the upper end connects saddle, back rod rear end is hinged with trailing wheel jaw and back support rod rear end respectively, front support rod rear end and back support rod front end are hinged with king-rod respectively, front wheel carrier is installed on the front wheel spindle, and the rear wheel fork head unit is on hind axle; Described power pack section comprises stretcher, foot-driven lever, pedal spindle and messenger chain, stretcher and foot-driven lever are hinged, foot-driven lever links to each other with pedal spindle, pedal spindle is placed through on the bar of back, it is characterized in that described messenger chain comprises preceding sprocket wheel, preceding chain, middle gap bridge sprocket wheel, rear chain and back sprocket wheel, preceding chain gear apparatus is on pedal spindle, middle gap bridge chain gear apparatus is in trailing wheel jaw upper end, back chain gear apparatus is on hind axle, preceding chain device is on preceding sprocket wheel and middle gap bridge sprocket wheel, and rear chain is installed on middle gap bridge sprocket wheel and the back sprocket wheel.
When travelling, rotate stretcher, sprocket wheel before driving by pedal spindle, gap bridge sprocket wheel in the middle of preceding chain drives, sprocket wheel after rear chain drives drives the trailing wheel rotation at last again, moves ahead to drive bicycle.
The collapsible speeding-up bike of the utility model hand-held design, described king-rod upper end is bent to form the saddle adjust bar forward, and saddle is placed on this saddle adjust bar.The saddle adjust bar is in order to regulate the front and back position of saddle.
The collapsible speeding-up bike of the utility model hand-held design, described saddle adjust bar and king-rod form oppositely directed " 7 " font structure.
Compare with the speed increasing mechanism of existing folding bicycle, power pack section of the present utility model adopts intermediate chain wheel to replace the protoplanet gear, under the prerequisite that reaches the same speedup effect of sample, greatly reduce the parts cost of power pack section, thereby also greatly reduce the productive costs of bicycle.
