Description

The convertible handlebar

Technical field

The utility model relates to the bicycle field, particularly is used for the convertible handlebar of folding bicycle.

Background technology

The Foldable handlebar of folding bicycle generally all is to load onto a folding joint to come handlebar is folded at the handle riser place on the market now, is contained on the folding bicycle, plays the folding effect of folding bicycle.But the said structure Foldable handlebar be sometimes because of can't the folding transverse tube of handlebar, makes can only form the single direction volume after folding, and the volume of other directions can't reduce, and influence the foldable integral effect after folding bicycle folds.

Summary of the invention

The purpose of this utility model is to design a kind of convertible handlebar, reduces by the volume after amounting to, and satisfies the volume control requirement after folding bicycle folds.

For achieving the above object, the technical solution of the utility model is,

The convertible handlebar is installed on the vehicle frame; Comprise that standpipe is installed on the vehicle frame; Left and right handle, its lower end is connected to the upper end of this standpipe; Flat pipe, it is the folding structure, two ends flexibly connect left and right handle respectively; Catch gear comprises, strut, and its two ends are slidedly arranged on left and right handle respectively, and are positioned at flat pipe below; This strut middle part is provided with a permanent seat, and this permanent seat is provided with the cavity body structure of a lower ending opening; Support tube, its inwall is provided with dividing plate, and these support tube two ends are inserted in respectively in strut permanent seat cavity body structure and the standpipe; The quick-release handle is arranged on the strut, and its lower end connects a screw rod, and this screw rod passes the dividing plate of strut and support tube, the dividing plate screw thread fit of its lower end and support tube; The also sheathed spring of this screw rod, this both ends of the spring are respectively against the dividing plate of strut and support tube.

Further, described strut two ends are respectively equipped with slide plate, establish groove on this slide plate, and this groove and left and right handle are complementary.

The permanent seat of described strut is circular.

Described support tube and standpipe are structure as a whole.

Again, described flat pipe is connected through the hinge by two flat pipes and forms.

In addition, described standpipe is the two sectional type structure, is made up of last lower standing tube, and connects by a folding joint.

The beneficial effects of the utility model

The utility model is by being provided with the flat pipe of folding structure between the left and right handle, left and right handle can be amounted to, and standpipe by being set, folding joint also can be realized folding, thereby the volume after this handlebar is amounted to is reduced, satisfy the volume control requirement after folding bicycle folds.

Fig. 2 is the structure for amplifying scheme drawing of strut among the utility model one embodiment;

Fig. 3 is the birds-eye view of Fig. 2.

The specific embodiment

Referring to Fig. 1～Fig. 3, convertible handlebar of the present utility model is installed on the vehicle frame; Comprise that standpipe 1 is installed on the vehicle frame; Left side handle 2, right handle 3, its lower end is connected to the upper end of this standpipe 1; Flat pipe 4, it is the two sectional type structure, its two ends flexibly connect left handle 2, right handle 3 respectively; Should flat pipe 4 be formed by connecting by hinge 5 by two

flat pipes

41,42;

Catch gear 6 comprises, strut 61, and its two ends are slidedly arranged on left handle 2, right handle 3 respectively, and are positioned at flat pipe 4 belows; These strut 61 middle parts are provided with a permanent seat 62, and this permanent seat 62 is provided with the cavity body structure 621 of a lower ending opening, and this permanent seat 62 is circular; Support tube 63, its inwall is provided with dividing plate 631, and these support tube 63 two ends are inserted in respectively in strut 61 permanent seat cavity body structures 621 and the standpipe 1; Quick-release handle 64 is arranged on the strut 61, and its lower end connects a screw rod 65, and this screw rod 65 passes the dividing plate 631 of strut 61 and support tube 63, dividing plate 631 screws thread fit of its lower end and support tube 63; The also sheathed spring 66 of this screw rod 65, these spring 66 two ends are respectively against the dividing plate 631 of strut 61 and support tube 63.

Described strut 61 two ends are respectively equipped with slide plate 67,67 ', establish groove 671,671 ' on this slide plate 67,67 ', this groove 671,671 ' and left handle 2, right handle 3 be complementary.

Described support tube 63 and standpipe 1 are structure as a whole.

Described standpipe 1 is the two sectional type structure, is made up of upper riser 11, lower standing tube 12, and connects by a folding joint 7.

When folding as need, earlier the quick-release handle 64 on the strut 61 of catch gear 6 is unclamped, under the effect of spring 66, strut 61 is certain altitude upwards, make the slide plate 67,67 ' at strut 61 two ends break away from left handle 2, right handle 3, and strut 61 revolved along standpipe 1 axis turn 90 degrees, more firmly left handle 2, right handle 3 between close up, the two

flat pipes

41,42 that make flat pipe 4 make progress into certain height by the coaxial two axial lines that becomes.Unclamp the quick-release handle 71 of folding joint 7, the upper riser 11 of handle riser 1 forwards to downwards and 12 one-tenth required angles of lower standing tube, makes the left handle 2, the right handle 3 that have closed up be folded into needed position downwards and finishes folding.

When needs open and use, left handle 2, right handle 3 are drawn back to both sides, rotation strut 61 is arranged on left handle 2, the right handle 3 slide plate 67,67 ' at strut 61 two ends, locks quick-release handle 64 again; The upper riser 11 of handle riser 1 upwards forwards to and lower standing tube 12 same axis then, and the quick-release handle 71 of locking folding joint 7 gets final product.
