Description
Technical field
The present invention relates to a kind of folding bicycle and manufacturing process thereof.
Background technology
At present commercially available folding bicycle folding rate is slow, and volume after folding is larger, is not easy to carry.
Summary of the invention
The object of this invention is to provide a kind of folding rate fast, volume after folding is little, portable folding bicycle.Another object of the present invention is to provide a kind of manufacturing process of folding bicycle.
Technical solution of the present invention is described folding bicycle, comprise that handle that front fork tube and front fork tube upper end connect is vertical the L shaped fixing bowl group pipe of the vertical front-wheel being connected with front fork tube fork, front fork tube middle part pivot joint, and the fold mechanism of front fork tube pivot joint, form front vehicle frame; Also comprise that trailing wheel, back breeches pipe that pipe cap that back breeches pipe and back breeches pipe upper end connect is connected with back breeches pipe fork are provided with the chain wheel actuating unit of two support tubes connections, wherein in a support tube, be inserted with a bar, vehicle frame after composition, between described L shaped fixing bowl group pipe and back breeches pipe, be provided with fold mechanism, its special character is: described fold mechanism lifts the front union of pipe side pipe end pivot joint, L shaped fixing bowl and organizes the double band iron link rod of pipe side pipe end pivot joint and form the L shaped slip between vertical and L shaped fixing bowl group pipe being lifted to pipe, L shaped slip by being sleeved on front fork tube; The position that wherein double band iron link rod, front union and back breeches pipe pipe cap intersect is configured as pin-joint mechanism by pivot; The free termination that double band iron link rod extends touches with seat bar; Described folding bicycle is also provided with the self-locking mechanism after folding.
As preferably: described pin-joint mechanism comprises that pipe cap, pipe cap and back breeches pipe pipe end are built-in with respectively between female and back breeches pipe mother Luo of mother Luo, pipe cap Luo and by Luo bar, pipe cap and back vent pipe end are linked together, make the pipe cap can axial rotation on back vent pipe end; The pipe cap of the female other end of Luo is radially provided with the perforation of a pair of coaxial line relatively, the pipe end of front union is the corresponding perforation that is provided with a pair of coaxial line also, between described front union perforation and pipe end, leave one section of constraint pipeline section, back breeches pipe pipe cap and the back breeches pipe being connected are inserted in front union constraint pipeline section together, after making to insert, can mutually rotate, again will be double band iron link rod middle part clamp front union, the perforation that makes double band iron link rod middle part and the perforation of front union and the perforation of having inserted pipe cap in front union align pivot joint, locking; When folding, because pipe cap is fixedly connected in front union, insert the pipe end of back breeches pipe and the pipe cap pipeline section axial constraint that suffers restraints again, back breeches pipe can only along pipe longitudinal axis relative to before union rotate, and then drive rear vehicle frame together to rotate.
