The invention relates to a rotary oil passing bicycle head structure and a bicycle. The rotary oil passing bicycle head structure is matched with a bicycle frame for use, and comprises a front fork vertical pipe, a front fork, a rear fork vertical pipe and a rear fork vertical pipe, wherein the front fork vertical pipe is rotationally assembled at the front part of the bicycle frame; the inner core piece at least comprises a first core part and a second core part which are sequentially arranged in the axial direction, a first annular groove, a second annular groove and a third annular groove are sequentially formed in the annular outer wall of the second core part, a first oil channel and a second oil channel are axially formed in the inner core piece, and the first end of the first oil channel communicates with the first annular groove; the second end of the second oil channel communicates with the free end of the first core part to form a first oil outlet, and the two ends of the second oil channel communicate with the second annular groove and the third annular groove correspondingly. The rotating piece comprises a rotating sleeve body, the position, corresponding to the third ring groove, of the second core part is movably sleeved with the rotating sleeve body, and a second oil outlet communicating with the third ring groove in the radial direction is formed in the side wall, corresponding to the third ring groove, of the rotating sleeve body; the oil sleeve piece comprises an oil sleeve body, the oil sleeve body is fixedly arranged at the positions, corresponding to the first ring groove and the second ring groove, of the second core part in a sleeving mode, a first oil inlet radially communicating with the first ring groove is formed in the side wall, corresponding to the first ring groove, of the oil sleeve body, and a second oil inlet radially communicating with the second ring groove is formed in the side wall, corresponding to the second ring groove, of the oil sleeve body. Hidden assembly of the oil pipe is achieved, interference of the oil pipe is avoided during steering of the bicycle, and smooth riding is achieved.

    本发明涉及一种回转过油车首结构及自行车。该回转过油车首结构,其搭配一自行车架使用,包括有:前叉立管,其转动装配于自行车架的前部;内芯件,其至少包括有轴向依次排列的第一芯部和第二芯部,第二芯部的环形外壁上依次开设有第一环槽、第二环槽和第三环槽,内芯件的内部轴向开设有第一油道和第二油道,第一油道的第一端连通第一环槽,且第二端连通至第一芯部的自由端以形成第一出油口,第二油道的两端分别连通第二环槽和第三环槽;回转件,其包括回转套体,回转套体活动套设于第二芯部对应第三环槽的位置,且其对应第三环槽的侧壁上设有径向连通第三环槽的第二出油口;油套件,其包括油套体,油套体固定套设于第二芯部对应第一环槽和第二环槽的位置,且其对应第一环槽的侧壁上设有径向连通第一环槽的第一进油口,其对应第二环槽的侧壁上设有径向连通第二环槽的第二进油口。本发明实现了油管隐藏式装配,且自行车转向时油管不产生干涉,顺畅骑行。
