Description

Adjustable height bicycle handlebar

Technical field

The utility model belongs to the field of bicycle manufacturing, in particular to a bicycle handlebar with adjustable height.

Background technique

When the existing bicycle handlebar height is adjusted, after parking is required, use the tool to loosen the fixing bolt of the center of the handlebar, adjust the height of the handlebar, and then tighten the bolt before continuing to ride. It is not possible to ride anyway at any time. Adjust the height of the handlebars. With the development and popularization of bicycle sports and the increasing level of bicycle functions in recent years, people have put forward higher and higher requirements for bicycle functions. The existing bicycle handlebars structure and function are far from meeting the requirements of cyclists. A bicycle that can adjust the height of the bicycle handlebar at any time during riding according to different riding postures, different heights, and different riding states of the rider.

technical problem

The purpose of the utility model is to provide a bicycle handlebar with adjustable height, which solves the problem that the bicycle handlebar can not be adjusted at any time during riding.

Problem solution

Technical solution

In order to achieve the above object, the technical solution of the present invention is: a bicycle handlebar with adjustable height, including a U-shaped fork, a center pillar, a crossbar, a handlebar, a fixed sleeve, a movable rod, a positioning device, and a wire tensioning device. The center column is vertically fixed above the middle of the U-shaped fork, and the horizontal bar is horizontally fixed on the upper part of the center column. The two ends of the cross bar are fixedly connected with the fixing sleeve, the movable rod is set in the fixed sleeve, and the outer wall of the movable rod is fixedly arranged in the axial direction. The upper end of the movable rod is fixedly connected with the handlebar. The positioning device comprises a positioning frame, a spring, a positioning pin and a wire rope. The positioning frame is mounted on the fixing sleeve, and a spring is arranged between the positioning pin and the positioning frame, and the outer end of the positioning pin and the wire rope The connecting pin is matched with the fixing hole, and the wire tensioning device is mounted on the handlebar and connected to one end of the wire rope.

The positioning device can be a hydraulically driven positioning pin.

BEST MODE FOR CARRYING OUT THE INVENTION

As shown in Figures 1, 2, and 3, an adjustable height bicycle handlebar includes a U-shaped fork 1, a center pillar 2, a crossbar 3, a handlebar 4, a fixed sleeve 5, a movable rod 6, a positioning device, and a wire. The tensioning device 8 has a central column 2 vertically fixed above the middle of the U-shaped fork 1. The horizontal bar 3 is horizontally fixed on the upper part of the center column 2. The two ends of the cross bar 3 are fixedly connected with the fixing sleeve 5, and the movable rod 6 is set in the fixing sleeve 5, The outer wall of the movable rod 6 is provided with a fixing hole 61 in the axial direction, and the upper end of the movable rod 6 is fixedly connected with the handlebar 4, and the positioning device comprises a positioning frame 71, a spring 72, a positioning pin 73 and a wire rope 74. The positioning frame 71 is mounted on the fixing sleeve 5. A spring 72 is disposed between the positioning pin 73 and the positioning frame 71. The outer end of the positioning pin 73 is connected with the wire rope 74. The positioning pin 73 is engaged with the fixing hole 61. The wire tensioning device 8 is mounted on the handlebar 4 and the end of the wire rope 74. connection.

The center pillar of the utility model is inserted into the handlebar sleeve at the front of the bicycle frame and is equipped with a ball bearing, which is installed in the same manner as the existing bicycle handle.

The positioning device of the utility model can adopt the above-mentioned fixing hole and positioning pin positioning, and can also adopt a series of transverse teeth on one side of the movable rod to form a rack, and the positioning pin can be meshed or separated from the rack to realize the activity. The rod is adjusted up and down, and the positioning pin of the present invention can also be driven by a hydraulic system instead of a spring and a wire rope.

When the device of the utility model is used, if the height of the handlebar needs to be adjusted, the finger moves the control handle of the wire tensioning device, the positioning pin is separated from the fixing hole, and the two hands are pulled upward or the crossbar is pushed down to reach a suitable height, and the wire is pulled loose. The device controls the handle. Under the action of the spring, the positioning pin is reset, the fixing hole is inserted, the height of the handlebar is fixed, and the entire adjustment process can be completed during riding.
