Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bicycles, in particular to a bicycle handlebar height adjustment device. Background Art
[0002] Currently, there are devices on the market that need to raise the handlebars, but they are all adjusted in a fixed way. When adjusting, the connection of the device needs to be loosened, and then the handlebars are adjusted to the corresponding height, and then fixed by using tools. They cannot be adjusted during riding. Some mountain bikes are equipped with butterfly-shaped handlebars that can play a certain role in alleviating the problem, but the handlebars are equipped with brakes, so when braking, you must hold the handlebars of the corresponding height with your hands. Therefore, in an emergency, your hands must be quickly placed on the corresponding handlebars, and you cannot brake at any time. Especially when the elderly are riding, they cannot respond to emergencies in time, which is prone to safety accidents. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a bicycle handlebar height adjustment device with a simple structure and easy operation. The height of the bicycle handlebar can be adjusted and can be adjusted during walking, which is more convenient to use and can effectively solve the problems in the background technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bicycle handlebar height adjustment device, comprising a vertical support column, a lower end vertical connecting buckle is fixed to one side of the lower end of the vertical support column, and a U-shaped fixing plate is fixed to the outer side of the upper end of the vertical support column, and a pin fixing short buckle is fixed to the end of the U-shaped fixing plate away from the vertical support column, and a rotating connecting ring is provided on the outer side of the pin fixing short buckle, and a horizontal support short column is welded on one side of the rotating connecting ring, and a handlebar fixing buckle is fixed to the end of the horizontal support short column away from the rotating connecting ring, and an adjustment fixing piece is provided on the top of the horizontal support short column to fix the rotating connecting ring and the pin fixing short buckle, a torsion spring is sleeved on the outer side of one end of the pin fixing short buckle, and a torsion spring end fixing seat is provided on the side of the vertical support column to block one end of the torsion spring, and the other end of the torsion spring is fixed to the horizontal support short column.
[0005] Furthermore, the pin shaft fixing short buckle includes a support tube, and an end fixing shaft fixedly connected to the U-shaped fixing plate is fixed at each end of the support tube, and the outer side of the support tube is evenly provided with adjustment card holes corresponding to the card joints of the adjustment fixing piece.
[0006] Furthermore, the adjustment fixing member includes a hinge seat fixed on the upper surface of the horizontal support short column, a rotating plate is fixed on the upper end of the hinge seat, a clamping joint is fixed on the lower side of one end of the rotating plate, and a pushing spring is provided between the lower side of the other end of the rotating plate and the upper surface of the horizontal support short column, and an opening corresponding to the clamping joint is provided on the rotating connecting ring.
[0007] Furthermore, the lower end vertical connecting buckle and the handlebar fixing buckle have the same structure, and both the lower end vertical connecting buckle and the handlebar fixing buckle include two semicircular clamping seats, which are fixed by screws.
[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: first, one end of the rotating plate is pressed to move the card joint out of the adjustment card hole, and then the horizontal support short column is rotated. The horizontal support short column is rotated along the pin shaft fixed short buckle by rotating the connecting ring, so that the upper and lower heights of the handlebar fixing buckle can be adjusted, thereby adjusting the height of the handlebar. When adjusting the appropriate height, one end of the rotating plate is bounced up by the jacking spring, and the card joint is clamped to the inside of the corresponding adjustment card hole, so that the rotating connecting ring and the pin shaft fixed short buckle are fixed. When adjusting during riding, the horizontal support short column is bounced up by the torsion spring, making it more convenient to raise the handlebar, avoiding the rider's palm numbness, arm and waist pain caused by the center of gravity being supported by the arms during long-term riding. The bicycle handlebar height adjustment device has a simple structure and is easy to operate. It can adjust the height of the automatic bicycle handlebar and can be adjusted while walking, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
