Description

Bicycle line control lever structure

The present invention relates to the technical field of bicycle control structures, and in particular to a control structure for adjusting the degree of softness and hardness of a bicycle shock absorber.

According to the current advanced bicycles, usually equipped with a shifting system, the higher-class vehicles are also equipped with a suspension fork control system to provide a more comfortable ride on the bumpy road, but ride on a flat road. If the suspension system is turned on, it is easy to cause the rider's fatigue when riding. Therefore, the suspension system of the mountain bike has evolved to adjust the softness and hardness of the control buffer, which is adjusted to be softer. The earthquake is suitable for riding bumpy roads, and being adjusted to a harder shock is suitable for riding on the road. Pull operation

The soft and hard of the suspension system, the general control structure is through the connection of the control line between the controller of the lever and the suspension structure, and the segmentation control of the shock and softness of the shock absorber is carried out through the pulling of the control line. For example, the Patent of the Republic of China Bulletin No. M455686, "Controlling the Fore-Staying Shock Absorber", the patent includes: a grip sleeve, which is a hollow body and is attached to one end of the handle tube of the two-wheeled vehicle. And a lever device, which is provided with a lever on a bundle of rings, and the collar is attached to the inner side of the grip sleeve, and is connected to the inner side of the grip sleeve by a lever device The end of the grip tube is tightened to one end of the handle tube of the two-wheeled vehicle, so that the grip sleeve is not easily detached, and the front fork of the two-wheeled vehicle can be shock-proofed. Control, so that it is saved in the past to use the bundle sleeve on the inner side of the grip sleeve, thereby reducing the cost.

The lever device is connected to the operating rod by a bundle of rings, and includes a first operating rod and a second operating rod. The two levers on the structure are required to pull the front fork through the connected control line. Controller; not only is it complicated in structure, but also relatively cumbersome in operation. It is the biggest drawback of the conventional "double lever shifting device".
