Two-stage brake adjustment structure

The present invention relates to a two-stage brake adjustment structure, and more particularly to a brake adjustment structure for a rider who provides a bicycle to adjust the brake force of the bicycle.

According to the advancement of science and technology and the improvement of living standards, leisure sports have been paid more and more attention by the people of the country. With the promotion of outdoor leisure activities, bicycle riding sports are gradually accepted by the people of the country; Popularization, the design of bicycles is also getting more and more advanced. Whether it is competition or casual bicycle style, it is not difficult for the bicycle design industry, but in pursuit of the ultimate appearance, the safety requirements are also It is an important requirement. The bicycle braking system is one of the most important tools for bicycle safety. The brake handle is the start switch for controlling the brake system. The quality of a brake handle is often related to the life of the rider. Safety, especially for riders who like fast driving, if the pressing force of the brake handle is not good enough, even if the rider has the best technology, it will be awkward. In serious cases, it will even cause unnecessary accidents and endanger the ride. The life safety of the occupant; the "Handle Handle Adjuster" of the Republic of China New Patent No. M396787 is used to solve To solve the above problems, the patent includes a base, a handlebar, a spring, and an adjusting component. The handlebar is pivoted at one end to the base, and the spring is disposed between the base and the handlebar. The adjusting component is disposed at an end of the handle bar adjacent to the base, and the adjusting component comprises an abutting bar, an adjusting wheel and a limiting rod, wherein the one end of the abutting bar is in the form of an abutting base, and the lever bar and the handle bar are presented. The telescopic arrangement is arranged, and the urging rod is screwed with the adjusting wheel, and the urging rod has a through groove for the limiting rod to be worn on the diametrical surface; thereby, the rotating adjusting wheel has the effect of restraining the rod by the rod, and The telescopic adjustment is performed with respect to the handlebar, and the pivoting angle of the handlebar and the base is changed by the telescopic rod to adjust the pressing distance of the handlebar; however, the patent adjusts the pressing lever to the bicycle grip. It is complicated and can only be used to adjust the distance between the handlebar and the grip; therefore, how to effectively adjust the travel distance of the brake lever to the grip to achieve the best brake feel by the innovative hardware design. Brake systems to meet the rollover prevention bicycle accidents, but the development of the industry and relevant researchers adjusted the brake system of the need to continue efforts to overcome and resolve the issue.
