The invention belongs to the technical field of bicycle accessories, and particularly relates to a full-angle supporting bicycle vertical pipe structure. The full-angle supporting bicycle vertical pipe structure comprises a front fork opening, a hollow middle pipe, a handlebar clamping base and an outer fixing piece. The right side of the front fork opening is connected with the handlebar clampingbase through the hollow middle pipe; the outer side of the handlebar clamping base is connected with base outer fixing piece through a fixing bolt; the front fork opening, the hollow middle pipe andthe handlebar clamping base are integrally machined and formed through the 3D forging technology; the height of the front fork opening ranges from 40 mm to 41 mm; and the pipe diameter of the hollow middle pipe ranges from 32 mm to 33 mm. Within the size specification range, the included angle between the hollow middle pipe and the horizontal plane of the front fork opening can be adjusted between+/- 7 and 35 degrees without changing the height of the front fork opening and the pipe diameter of the hollow middle pipe. By adjusting the sizes of the front fork opening and the middle pipe, the adjustment between +/-7 and +/-35 degrees is met under the condition that the appearance and the structure are not changed, and the appearance and the structure of the vertical pipe are unified; the problem that the consistency of consumers and finished automobile factories is not unified in the aspect of part selection is solved.
本发明属于自行车配件技术领域,尤其是涉及一种全角度支持自行车立管结构。它包含前叉口、空心中管、车把卡座、外固定件;所述的前叉口的右侧通过空心中管连接有车把卡座;车把卡座的外侧通过固定螺栓连接有外固定件;所述的前叉口、空心中管、车把卡座三者通过3D锻造技术一体加工成型;其中;所述的前叉口高度为40‑41mm;空心中管的管径为32‑33mm;在该尺寸规格范围内,能够实现空心中管与前叉口水平面之间的夹角正负7‑35度调节而不改变前叉口的高度和空心中管的管径。它通过调节前叉口以及中管的尺寸,使其在不改变外形和结构的情况下满足±7到±35之间的调节,统一了立管的外形和结构;解决了消费者与成车厂在选件上一致性不统一的难题。
