The invention discloses a pipe clamp for a hub and a sleeve of a bicycle, which comprises arc-shaped clamping rings including a first arc-shaped clamping ring and a second arc-shaped clamping ring, the buffering ring is provided with a double-layer attaching part, and the inner ring of the arc-shaped clamping ring is in contact with the buffering ring; and in the radial outward direction of the buffer ring, the attaching part sequentially comprises a covering section and a convex tongue section, the covering section is clamped by the clamping position, and a kidney-shaped hole allowing a bolt to penetrate through is formed in the covering section. The kidney-shaped holes comprise the first kidney-shaped hole and the second kidney-shaped hole which are perpendicular to each other and attached in a crossed mode, a square through hole is formed in the overlapping position of the first kidney-shaped hole and the second kidney-shaped hole, the outline of the square through hole is square, the side length of the square through hole is smaller than the diameter of the bolt, and the diagonal length of the square through hole is larger than the diameter of the bolt. By the adoption of the buffer ring, a bicycle sleeve or a hub can be buffered and protected, the locating and tightening effect of the buffer ring is good, and the buffer ring also has the effect of improving assembly similar to that of a gasket for a bolt.
本发明公开了一种用于自行车花鼓和套管的管夹,包括弧形卡环,包括第一弧形卡环、第二弧形卡环;缓冲圈,存在双层的贴合部,弧形卡环的内圈接触有缓冲圈;沿缓冲圈的径向向外方向,贴合部依次包括覆盖段和凸舌段,覆盖段被卡接处夹持,覆盖段内具备供螺栓穿过的腰型孔。腰型孔包括相互垂直交叉贴合的第一腰型孔、第二腰型孔,第一腰型孔与第二腰型孔的重合处形成方形通孔,方形通孔的轮廓为正方形,方形通孔的边长小于螺栓的直径,方形通孔的对角线长度大于螺栓的直径。采用此发明能对自行车套管或花鼓起到缓冲保护,缓冲圈定位于收紧效果好,缓冲圈也为螺栓起到类似垫圈的改善装配的效果。
