Adjustable fork offset and height structure

Abstract

An adjustable fork offset and height structure includes a connecting post with a top cover fixedly mounted on its bottom. Two symmetrically arranged outer legs are located below the connecting post, with a shock absorber rod slidably connected to the top of each leg and fixedly connected to the bottom of the top cover. An adjustment mechanism is located on the outer side of the two outer legs, comprising a fork hook and an eccentric insert inside. By engaging and rotating the eccentric insert with the hook hole, the fork offset and height can be adjusted, achieving stepped or stepless flexible adjustment. This further enhances assembly flexibility and reduces mold design costs, providing convenient installation and application flexibility.

Claims

1. A structure for adjustable fork offset and height, comprising a connecting post, characterized in that: a top cover is fixedly provided at the bottom of the connecting post, two outer legs are symmetrically arranged below the top cover, a shock absorber rod is slidably connected to the top of each outer leg and fixedly connected to the bottom of the top cover, and an adjustment mechanism is provided on the outer side of each outer leg; the adjustment mechanism includes a fork pawl, which has a pawl hole inside, a plurality of insert grooves are arranged in a circumferential array inside the pawl hole, and an eccentric insert is provided inside the pawl hole, a plurality of insert strips are fixedly arranged in a circumferential array on the outer side of the eccentric insert, and a connecting hole is provided inside each insert strip, and a threaded groove is formed inside the connecting hole.

2. The adjustable fork offset and height structure as described in claim 1, wherein, A connecting sleeve is fixedly provided on the outer side of each of the two outer legs, and a stabilizing frame is further fixed on the outer side of each connecting sleeve.

3. The adjustable fork offset and height structure as described in claim 1, wherein, Both of the aforementioned outer feet are equipped with pneumatic buffer elements, which work in conjunction with the shock absorber rod to achieve a shock absorption effect.

4. The adjustable fork offset and height structure as described in claim 1, wherein, The size of the insert strip corresponds to the insert groove inside the hook hole, and they fit together to improve installation stability.

5. The adjustable fork offset and height structure as described in claim 1, wherein, The two hook holes mentioned above are equipped with tension grooves to securely fit mounting posts of different sizes.

6. The adjustable fork offset and height structure as described in claim 1, wherein, The aforementioned connecting columns, top covers, outer feet, and shock absorber rods are all coated with anti-rust coatings to prevent metal components from rusting and extend their service life.

7. A structure for adjusting the offset and height of a fork, comprising a connecting post, a top cover fixedly mounted on the bottom of the connecting post, two symmetrically arranged outer legs below the top cover, a shock absorber rod slidably connected to the top of each outer leg and fixedly connected to the bottom of the top cover, and an adjustment mechanism provided on the outer side of each outer leg; the adjustment mechanism includes a fork pawl, which has a pawl hole inside. The pawl hole has a regular polygonal structure and an eccentric insert of a corresponding shape inside. The eccentric insert can rotate around its central axis, and has multiple insert strips on its outer side. Each insert strip has a connecting hole inside, and the connecting hole has a threaded groove inside; when the eccentric insert rotates to different angles, the relative position of its connecting hole and the pawl hole will change, thereby adjusting the position of the mounting post and thus changing the offset and height of the fork. The eccentric insert can be designed as a segmented rotational structure with a limited positioning angle, or as a stepless rotational structure, to improve the degree of adjustment freedom and enhance the anti-rotation and anti-loosening effects.

8. The adjustable fork offset and height structure as described in claim 7, wherein, The eccentric insert is equipped with an anti-rotation positioning structure, which can be positioned at multiple rotational angles.

9. The adjustable fork offset and height structure as described in claim 7, wherein, The eccentric insert can rotate infinitely relative to the claw hole to be installed and adjusted at any angle.

10. The adjustable fork offset and height structure as described in claim 7, wherein, The hook hole has a regular octagonal structure.
