Description

Technical Field

[0001] This utility model relates to the field of bicycle shock-absorbing front fork technology, and in particular to a fully sealed protective bicycle shock-absorbing front fork. Background Technology

[0002] As people's demands for cycling comfort and handling continue to increase, suspension forks have become an important component of modern bicycles. They can effectively absorb road bumps, reduce the impact of vibrations on riders, improve riding comfort and handling, and allow riders to have a smoother riding experience under different road conditions. Bicycles are not only used for daily commuting, but also widely used in various sports scenarios such as mountain biking, road racing, and off-road adventure. Under these complex road conditions, the fork needs to frequently cope with various impacts and vibrations, which puts higher demands on its shock absorption performance and durability, prompting manufacturers to continuously develop more advanced suspension fork technologies.

[0003] Currently, most bicycle suspension forks on the market consist of fork shoulders and fork tubes. Early bicycle suspension forks mostly used simple insert or screw connections to the frame. While this connection method is stable, it requires precise alignment of the holes during installation, and problems such as stripped threads or component deformation are prone to occur during installation, increasing the difficulty of installation. For example, in the installation of some mountain bike suspension forks, the tolerance requirements for the fit between the frame head tube and the fork steerer tube are high, and even a slight deviation will lead to installation problems. At the same time, some suspension forks have complex structural designs and irregular component shapes in pursuit of high performance and special functions. In the narrow frame installation space, these components are prone to interfering with the frame or other accessories, affecting installation and rotation. For example, the brake mounts and protruding parts of the travel adjustment devices on some forks may collide with the frame cables or water bottle cages, resulting in inconvenient installation or obstructed fork rotation.

At the same time, the bottom of the fixed shaft 202 is fixedly connected to the bottom of the inner wall of the fork barrel 205. When the wheel installed at the bottom of the fork barrel 205 is subjected to force, it will drive the fixed shaft 202 to slide on the inner wall of the travel tube 201. Meanwhile, the sliding plate 203 slidably connected in the middle of the fixed shaft 202 will be subjected to the elastic force of the spring 204 fixed at its bottom, so that the sliding plate 203 slides on the outer wall of the limiting groove 206 opened in the fork barrel 205, thereby achieving a highly efficient shock absorption effect.
