Below, described technical scheme is described further:
One support set is set, the square opening that is provided with on described square core bar and the support set is adaptive, and support set moves on square core bar, and described square core bar is upper to be provided with a retracing spring in the support set bottom, insert with a straight-bar in the location hole of the spring of square core bar bottom setting, and retracing spring one end position is fixed.Like this, support set, retracing spring, the common formation one of straight-bar three have the structure of spring function, so that tap is folding.
Below, described technical scheme is described further:
One handle is set, and handle is provided with pin hole, matches with the connecting bore that is provided with on the support set, passes the connecting bore on handle pin hole and the support set and handle is fixed on the support set with a latch;
Be socketed with a guard ring on the described handle, the cavity volume that constitutes between guard ring and support set is used for ccontaining hollow the transverse tube tube wall.
The support set head of described support set is spill, and concave curvature is identical transverse tube curvature with hollow.
When the utility model was used, the brake lever seat was installed in the guard ring bottom that is positioned on the handle, and an end osed top handle is installed in brake lever seat bottom.Make that the position of guard ring on handle fixed.
Folding handlebar with structure described in the utility model, its dynamic duty process prescription is as follows:
When folding handlebar was in deployed condition, under action of reset spring, the support set head placed hollow in transverse tube one end, and guard ring has contained hollow the transverse tube tube wall.Handle is enclosed within hollow on the transverse tube tube wall and fix by guard ring; Folding handlebar is stable when riding with assurance.
When needs are in folded state with folding handlebar, grasping handle outwards stretches, make guard ring separate the transverse tube tube wall with hollow, the support set head is touched hollow the transverse tube port, and along hollow transverse tube guide groove groove to inner rotary 90 degree, pressurized when retracing spring is outwards stretched by handle to the bottom be retracted to hollow transverse tube guide groove groove to when inner rotary 90 is spent, upwards withstanding the support set head, make the support set head be close to hollow, and reach the technique effect of relative fixed handle on the transverse tube outside face;
The utility model design science, of a tightly knit structure, good stability, both artistic and practical are for the production of folding bicycle tap provides a kind of suitable equipment.
