Description

Folding bicycle handlebar collection structure

technical field

The invention relates to a handle structure of a foldable bicycle, especially designed for the foldable handle structure of a foldable bicycle, and provides a foldable handle foldable structure with safe use, convenient operation and smooth operation.

Background technique

The handle folding of early foldable bicycles (such as the No. 098208607 "foldable bicycle handle standpipe" new patent applied by the applicant before) is mainly to provide a folder between the handle riser and the front wheel fork, so that the handle is vertical The tube can be folded and folded against the side of the frame by rotating 180 degrees downwards with the folder.

For the folding of the handlebars of the above-mentioned early folding bicycles, since the handlebars are folded and folded against the side of the frame according to the 180-degree downward rotation of the folder, the handles on the handlebars and the accessories on the handles will Along with the downward rotation of the handle stem, it is folded against the side of the frame, so that the width and volume of the folded bicycle will only be increased, which is not conducive to carrying and a large amount of storage and transportation; at the same time, the operation and use of the folder is not smooth ,Convenience.

In order to improve the deficiencies in the handle folding structure of the above-mentioned early folding bicycles, the applicant then designed a new patent No. 102214197 "Folding Bicycle Handle Structure". The other end of the quick release assembly is provided with a beam interface, which extends to the right and rearwards on the right side of the frame, and the beam interface can provide the threading and beam connection of the handle riser; It can be retracted down to the right side of the frame, and the handle at the upper end of the handle stem can be folded above the folded frame, so that the width and volume of the folded frame can be further reduced, and it is more convenient Carry and reduce storage and transportation space.

The above-mentioned No. 102214197 "Folding Bicycle Handlebar Structure" new patent, although it helps to reduce the width and volume of the folded frame, provides more convenient portability and helps reduce storage and transportation space; The harness interface of the piece used to connect the handle stem is offset to the right and rearward and extends to the right side of the frame, so the handle stem and the front wheel fork are not on the same axis, so that in addition to causing visual obstacles , and there are also safety concerns in riding steering operations.

Contents of the invention

In order to improve the deficiencies in the above-mentioned collapsible bicycle handlebar structure, the present invention provides a collapsible bicycle handlebar collapsible structure, which is safe to use and convenient to operate.

The technical solution adopted by the present invention to solve its technical problems is:

A handle folding structure of a foldable bicycle, comprising a foldable frame, a handle riser is assembled to the upper end of the front wheel fork of the foldable frame, and a handle is assembled to the upper end of the handle riser; wherein:

There is a set of sockets between the front wheel fork frame and the handle riser, the assembly seat includes a first seat body and a second seat body, the first seat body is assembled on the upper end of the front wheel fork frame, and the second seat body can provide a handle The sleeve of the standpipe, the handle standpipe can move up and down according to the second base body, the first base body and the side of the second base body are pivoted together with a pivot pin, and the second base body can also rotate according to the pivot pin , the other side of the first seat is provided with a quick-release buckle, and the other side of the second seat forms a fastening end, the quick-release buckle of the first seat can be fastened to the buckle end of the second seat, The first seat body and the second seat body are firmly combined, and then the handle standpipe can be assembled on the upper end of the front wheel fork, and the handle standpipe and the front wheel fork are on the same axis.

With the above structure, loosen the quick-release buckle and rotate the handle stem to drive the second base body to rotate to one side according to the pivot pin, so that the handle riser is shifted to the side of the folding frame, and then the handle stem can be moved to the side of the folding frame. It is lowered and retracted to one side of the foldable bicycle frame, thereby providing a safe, convenient and convenient foldable bicycle handle collection structure.
