The invention discloses a bicycle vertical tube and a manufacturing method thereof. The bicycle vertical tube comprises a vertical tube body and a shoulder cover, wherein the shoulder cover is integrally connected with the vertical tube body; a through hole penetrating through the shoulder cover is formed in the shoulder cover; the axis of the through hole is perpendicular to the axis of the vertical tube body; and a groove or a bulge is formed in the hole wall of the through hole. According to the bicycle vertical tube disclosed by the embodiment of the invention, the shoulder cover is integrally connected with the vertical tube body, so that a welding connecting manner is replaced, and the connecting stability is improved; and besides, the vertical tube structure provided by the invention can change the connecting manner of a conventional front fork structure, and the welding connecting manner is replaced, so that the defects of unstable connection and the like caused by welding areovercome.

    本发明公开一种自行车竖管及其制造方法。其中,该自行车竖管包括竖管本体和肩盖,肩盖与竖管本体一体连接,肩盖设有贯穿肩盖的贯穿孔,且贯穿孔的轴线与竖管本体的轴线垂直;贯穿孔的孔壁设有凹槽或凸起。本实施例中自行车竖管通过肩盖和竖管本体的一体连接,替代焊接的连接方式,提高连接稳定性,同时本发明提供的竖管结构可以改变现有前叉结构的连接方式,替代焊接的连接方式,克服焊接带来的连接不稳定等缺陷。
