Abstract
The invention discloses a bicycle front fork structure and a manufacturing method thereof. Wherein the bicycle front fork structure includes a standpipe and a front fork leg, and the standpipe is provided with a through hole; the front fork leg includes an integrally connected arc portion and two assembly portions, and the two assembly portions are arranged oppositely and connected by the arc portion, The arc part is installed in the through hole; wherein, one of the wall of the through hole or the outer periphery of the arc part is provided with a groove, and the other is provided with a protrusion, and the groove and the protrusion are matched and connected. The bicycle front fork structure provided by the invention can change the connection mode of the existing front fork structure, replace the connection mode of welding, and overcome defects such as unstable connection caused by welding.
Description
technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle front fork structure and a manufacturing method thereof. Background technique [0002] The guiding system of a bicycle is composed of components such as handlebars, front forks, front axles, and front wheels. The rider can change the driving direction and maintain the balance of the body by manipulating the handlebar. The front fork connects the handlebar and the front axle. The stability of the front fork plays an important role in the safety of use. The front fork includes a connected vertical pipe and front fork legs. The vertical pipe is connected to the handlebar, and the front fork legs are connected to the front axle. The firmness of the connection between the front fork legs and the vertical pipe plays a vital role in the overall firmness of the front fork. . In the related art, the front fork leg and the standpipe are connected by welding, which is prone to ...
