Background technology
Disclosed Folding Bicycle all has the structure of folding handlebar on the market; A kind of folding handlebar adopts point of interruption rotational structure; Be about to tap and open the binding constraint device, change the direction of tap, make it side direction and place along certain point on the handlebar supporting tube; To reduce leading occupation space, convenient folding; Another kind then adopts direct rotational structure, promptly directly at the tap middle part pivot point is set, and the leading width after folding reduces, and can shrink downwards, to reach convenient and practical technique effect; All there is complex structure in folding handlebar analysis from above two kinds of structures, and after tap launched, leading elasticity should not tighten, for riding of folding bicycle brought certain hidden danger; Thereby be necessary innovative design in addition on this basis.
Summary of the invention
The purpose of this invention is to provide on a kind of folding handlebar with transverse tube bonded assembly structure.
Technical scheme of the present invention is achieved in that
Provide on a kind of folding handlebar with transverse tube bonded assembly structure; It is characterized in that: a support set is set rotarys connection transverse tube with hollow, a square core bar is arranged, the square opening that is provided with on said square core bar and the support set is adaptive; Support set moves on square core bar; Said square core bar is upper to be provided with a retracing spring in the support set bottom, inserts 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.
Below, further describe with folding handlebar on the transverse tube ways of connecting:
Said hollow is provided with knock hole to transverse tube; Said knock hole be placed in hollow and cooperate the keyway on the retainingf key in the transverse tube; Retainingf key one end is provided with the retainingf key guide groove; Hollow is provided with hollow to transverse tube one end the transverse tube guide groove, and to identical, retainingf key is provided with axis hole in retainingf key guide groove position transverse tube guide groove groove for said retainingf key guide groove and hollow; Said square core bar one end places in the retainingf key guide groove, and the through hole that square core bar one end is provided with cooperates with axis hole, passes through hole and axis hole and with square core bar one end positioning of rotating with an axis.
One handle is set, and handle is provided with pin hole, and the connecting bore that is provided with on said pin hole and the support set matches, and 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 said 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 said support set is spill, and concave curvature is identical transverse tube curvature with hollow.
When the present invention 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 the position of guard ring on handle fix.
Folding handlebar with structure according to the invention, its dynamic duty process prescription is following:
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, the 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;
Design science of the present invention, of a tightly knit structure, good stability, both artistic and practical, the production leading for folding bicycle provides a kind of suitable equipment.
Description of drawings
Fig. 1 is the unitized construction scheme drawing of an embodiment of the present invention.
Fig. 2 is the installation effect scheme drawing of Fig. 1.
Fig. 3 is the constructional drawing when handle launches among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing 1 explanation embodiments of the invention, but be not limited to following examples:
Provide on a kind of folding handlebar with transverse tube bonded assembly structure; One hollow is set transverse tube 1; Hollow is provided with knock hole 11 to transverse tube 1; Said knock hole 11 be placed in hollow and cooperate the keyway 21 on the retainingf key 2 in the transverse tube 1, it is interior and retainingf key 2 is fixed on hollow in the transverse tube 1 to insert knock hole 11 and keyway 21 with pin; One end of retainingf key 2 is provided with retainingf key guide groove 22; Hollow is provided with hollow to transverse tube 1 one ends transverse tube guide groove 12; To identical, retainingf key 2 is provided with axis hole 23 in retainingf key guide groove 22 positions transverse tube guide groove 12 grooves for said retainingf key guide groove 22 and hollow; One end of one square core bar 3 places in the retainingf key guide groove 22; The through hole 31 that one end of square core bar 3 is provided with cooperates with axis hole 23; Pass through hole 31 with axis hole 23 and with square core bar 3 one end positioning of rotating with an axis, said square core bar 3 around axis along retainingf key guide groove 22 and hollow the common groove of transverse tube guide groove 12 to inner rotary.
