The invention relates to the field of seat tube adjustment, and discloses a bicycle seat tube structure capable of being rapidly adjusted, the bicycle seat tube structure is characterized by comprising a fixing sleeve and a seat tube body, a plurality of fixing grooves are formed in the fixing sleeve and distributed in the length direction of the fixing sleeve, and one end of the seat tube body is in sliding fit with the fixing sleeve and is provided with a plurality of sliding blocks; a push rod is arranged in the seat tube body and slides in the axis direction of the seat tube body, and a connecting assembly is arranged at the end, arranged in the fixing sleeve, of the seat tube body, so that when the push rod moves in the direction close to the connecting assembly, the sliding blocks get close to each other and break away from the fixing grooves, and the seat tube body and the fixing sleeve can relatively slide. When the push rod moves in the direction far away from the connecting assembly, the sliding blocks are far away from each other and clamped with the fixing grooves to fix the seat tube body, and the seat tube has the advantages of being capable of being rapidly disassembled and assembled and rapidly adjusted, reliable in locking and not obvious in cost and weight increase.

    本发明涉及调节座管领域,公开了一种可快速调节的自行车座管结构,其技术方案要点是包括固定套和座管本体,固定套上开设有若干固定槽,固定槽沿固定套的长度方向分布,座管本体的一端与固定套滑动配合并设置有若干滑块,座管本体内设置有推杆,推杆在座管体沿轴线方向滑动,座管本体内置于固定套的一端设置有连接组件,使得当推杆向靠近连接组件的方向移动时,滑块相互靠近并脱离固定槽以使座管本体和固定套之间能够相对滑动,当推杆向远离连接组件的方向移动时,滑块相互远离并与固定槽相互卡合以固定座管本体,并具有可以快速拆装、快速调节,锁定可靠,并且成本和重量增加不明显的特点。
