Description

Handlebar Assembly for Folding Bicycles

technical field

The utility model relates to a folding handlebar, in particular to a handlebar assembly suitable for a folding bicycle.

Background technique

In a folding bicycle, in order to reduce the folding volume, the handlebar is also designed as a foldable structure. Folding handlebars on the existing market, the handlebars with simple structure are unreliable in locking, the gap is relatively large during use, and there is shaking; the folding handlebars with complex structure are bulky, heavy, and costly.

Contents of the invention

The technical problem to be solved by the utility model is to provide a handlebar assembly of a folding bicycle with simple structure, convenient operation and reliable locking.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a handlebar assembly of a folding bicycle, including a pair of handlebars that can be folded separately, a tightening ring, a handlebar riser, The eccentric handle, the connecting rod and the adjusting nut hinged with the eccentric handle, the tightening ring is fixed above the handlebar standpipe, there is a horizontal long groove on the opposite side of the opening of the tightening ring, and the two ends of the bottom of the tightening ring are respectively opened to accommodate the handlebar. Each handlebar is slidably connected with the long groove of the tightening ring by a bolt and the notch of the size of the diameter.

The long groove is divided into two sections, which are symmetrically formed on the opposite side of the opening of the tightening ring with the handlebar standpipe as the axis of symmetry.

A rolling sleeve is added to the contact between the bolt and the long groove.

A hoop for clamping the folded handlebar is fixed on the handlebar riser.

The beneficial effect of the utility model is that the two handlebars are locked by a simple eccentric structure, the structure is simple, the operation is convenient, and the locking is reliable.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figures 1, 2, 3, and 4, the handlebar assembly of the utility model folding bicycle includes a pair of handlebars 9, a tightening ring 4, and a handlebar standpipe 5 that can be folded respectively, which are left and right symmetrical and have the same folding structure. , the eccentric handle 1 and the connecting rod 2 hinged with the eccentric handle 1 and the adjusting nut 3, the tightening ring 4 is fixed above the handlebar standpipe 5, and the opposite side of the opening 6 of the tightening ring 4 is provided with a horizontal long groove 7 for tightening Ring 4 bottom two ends respectively have breach 8 that can accommodate the diameter of handlebar 9, and each handlebar 9 is slidably connected with fastening ring long groove 7 by a bolt 10 respectively.

In this embodiment, the long groove 7 is formed in two sections, which are symmetrically formed on the opposite side of the opening 6 of the tightening ring with the handlebar standpipe 5 as the axis of symmetry.

In order to reduce friction, a rolling sleeve 11 is added to the contact between the bolt 10 and the long groove 7 . And a hoop 12 for blocking the folded handlebar 9 is fixed on the handlebar riser 5 .

The eccentric handle 1 presses the tightening ring 4 to deform, thereby locking the handlebar 9. When the rotating eccentric wheel reaches the lowest position, the handlebar 9 moves to the two ends of the tightening ring 4 along the long groove 7, and rotates around the bolt 10 to Notch 8, and clamped in the hoop 12 on the standpipe.

The embodiments described above are only used to illustrate the technical ideas and characteristics of the present utility model, and its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and the present utility model cannot be limited only by this embodiment. The patent scope of the utility model, that is, all equivalent changes or modifications made to the spirit disclosed in the utility model still fall within the patent scope of the utility model.
