Problems solved by technology

[0002] Handlebars currently on the market are generally connected in a fastened manner. A lower cover is set on the handlebar standpipe, and the handlebar cross tube is clamped between the upper cover and the lower cover by the upper cover. Fix the two sides of the upper cover plate and the lower cover plate with bolts, so as to connect the handlebar to the front fork. Since the handlebar needs to be rotated continuously during riding, this connection method takes a while. Long, the bolts are easy to loosen, and the handlebar and front fork will deflect along the circumferential direction, reducing the steering precision of the handlebar

Embodiment

[0023] Please refer to Figure 1 to Figure 3 As shown, the present invention discloses a handlebar connection structure, comprising a handlebar 1, a front fork 2 and a headset 3, the handlebar 1 is provided with a connection port 11, and the front fork 2 includes a connection at the top for inserting the connection port 11 Pipe 21, the cross-section of the connecting pipe 21 and the cross-section of the connecting port 11 are all polygonal structures and the two are compatible. Since both are polygonal structures, the connecting pipe 21 cannot be rotated in the connecting port 11, and the The top of the pipe wall is provided with an expansion port 211 in the axial direction. The headset 3 is arranged in the lumen of the connecting pipe 21 to fasten the handlebar 1 and the front fork 2. The minimum outer diameter of the headset 3 is the same as the inner diameter of the connecting pipe 21. fit.

[0024] The polygonal structure is a regular hexagonal structure or a regular quad...

Abstract

The handlebar connecting structure comprises a handlebar, a front fork and a bowl set, the handlebar is provided with a connecting opening, the front fork comprises a connecting pipe which is located at the top end and used for being inserted into the connecting opening, and the cross section of the connecting pipe and the cross section of the connecting opening are each of a polygonal structure and are matched with each other; an expansion opening is formed in the top end of the pipe wall of the connecting pipe in the axial direction, and the bowl set is arranged in a pipe cavity of the connecting pipe. According to the handlebar connecting structure, a connecting opening of a handlebar and the cross section of a front fork connecting pipe used for being inserted into the connecting opening are both of a polygonal structure and matched with each other, so that the connecting pipe cannot rotate in the connecting opening, meanwhile, a bowl set arranged in the connecting pipe is rotated, the outer diameter of the bowl set is increased, and the pipe wall of the connecting pipe is pushed to expand outwards; the outer wall of the expanded connecting pipe is tightly attached to the inner wall of the connecting opening of the handlebar, so that the connecting pipe and the connecting opening are fixedly and stably connected, the handlebar and the front fork are prevented from deflecting in the circumferential direction, and steering accuracy of the handlebar is guaranteed.

Description

technical field [0001] The invention relates to the technical field of handlebars, in particular to a handlebar connection structure. Background technique [0002] At present, the handlebars on the market are generally connected in a fastened manner. A lower cover is set on the handlebar riser, and the upper cover is used to clamp the handlebar cross tube between the upper cover and the lower cover, and then Use bolts to connect the two sides of the upper cover plate to the two sides of the lower cover plate, so that the handlebar is connected to the front fork. Since the handlebar needs to be rotated continuously during the riding process, this connection method takes a long time. Long, the bolts are easy to loosen, and the handlebar and front fork will deflect in the circumferential direction, reducing the steering accuracy of the handlebar. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a handlebar connection structure. The cross-s...
