The invention relates to an improved rotary oil passing bicycle head structure and a bicycle. The improved rotary oil-passing bicycle head structure is matched with a bicycle frame for use and comprises a bicycle head pipe, an oil passing pipe and a rotating oil passing pipe, the inner core piece at least comprises a first core part, a first convex ring part and a second core part which are sequentially arranged in the axial direction, and a first oil channel and a second oil channel which are axially formed in the inner core piece, and a first ring groove is formed in the annular outer wall of the first core part; the rotating piece at least comprises a rotating sleeve body, the position, corresponding to the first ring groove, of the second core part is movably sleeved with the rotating sleeve body, and a first oil outlet communicating with the first ring groove in the radial direction is formed in the side wall, corresponding to the first ring groove, of the rotating sleeve body; the locking pieces are arranged at the two ends of the motorcycle head pipe so that the inner core piece can be axially positioned after being inserted into the motorcycle head pipe; the second end of the second oil channel communicates with the first annular groove, and the second end of the first oil channel communicates with a second oil outlet. 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.
本发明涉及一种改进型回转过油车首结构及自行车。该改进型回转过油车首结构,其搭配一自行车架使用,包括有:车头管;内芯件,其至少包括有轴向依次排列的第一芯部、第一凸环部、第二芯部,以及轴向开设于内芯件内部的第一油道和第二油道,第一芯部的环形外壁上开设有第一环槽;回转件,其至少包括回转套体,回转套体活动套设于第二芯部对应第一环槽的位置,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出油口;锁定件,其设置于车头管的两端以使得内芯件在车头管上插装后轴向定位;其中,第二油道的第二端连通第一环槽,第一油道的第二端连通有第二出油口。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。
