The invention discloses an oil path pre-embedding structure of a bicycle frame, a handle connecting structure and a bicycle, the oil path pre-embedding structure comprises a frame body, a handle connecting structure, a handle connecting structure and a handle connecting structure, the frame body is composed of a plurality of pipe fittings, and the pipe fittings are defined by pipe walls; the oil conveying pipe is fixedly arranged in at least one pipe fitting of the frame body, the oil conveying pipe has the extending direction consistent with that of the pipe fitting, and the outer side surface of the oil conveying pipe is connected with the pipe wall of the pipe fitting in an attached mode; every two pipe joints correspondingly communicate with the two ends of one oil conveying pipe, the pipe joints are fixedly arranged on the pipe wall of the pipe fitting and exposed out of the pipe fitting, and the pipe joints and the oil conveying pipes are fixedly connected in a sealed mode through inserting cores which are arranged on the pipe joints, stretch into the oil conveying pipes and are in interference fit with the inner walls of the oil conveying pipes. According to the oil way pre-embedded structure, a brake line does not need to be arranged on the frame in a penetrating mode in the later period, and the assembling difficulty is lowered.
本发明公开了一种自行车车架的油路预埋结构、把手连接结构和自行车,该油路预埋结构包括:车架本体,其由若干管件组成,管件由管壁围合形成;输油管,车架本体的至少一管件内固设有输油管,该输油管具有与该管件一致的延伸方向,且该输油管的外侧表面与该管件的管壁贴合连接;管接头,每两管接头对应连通于一输油管的两端,管接头固设于管件的管壁并露出于管件外侧,并与输油管通过设于管接头且伸入输油管并与输油管的内壁过盈配合的插芯形成密封固接。该油路预埋结构使车架无需在后期穿设刹车线路,降低了装配难度。
