The invention belongs to the technical field of bicycle structures, and particularly relates to a folding linkage self-locking bicycle frame which is characterized in that the upper part of a steering shaft below a handlebar rod is hinged to the lower part of a steering shaft above a front fork, an upper steering shaft sleeve is hinged to the upper part of the steering shaft, and a steering shaft sleeve is hinged to the lower part of the steering shaft; a second connecting part is hinged to the front end of a second movable connecting piece through a quick-release connecting shaft, the rear end of the second movable connecting piece is hinged to a third connecting part, a fourth connecting part is hinged to the rear end of a first movable connecting piece, the front end of the first movable connecting piece is hinged to a first connecting part through a quick-release connecting shaft, and a second linkage tooth and a first linkage tooth are meshed to form a linkage device which is a self-locking structure locking frame. A transmission hinge part is rotatably hinged to the upper portion of the head pipe connecting piece to form a second part of the self-locking structure, a saddle stand column is hinged to a third connecting part, a quick-release handle is hinged to the middle of one side of two quick-release connecting shafts, and a driving device is hinged to the lower portion of a fourth connecting hole in a first movable connecting piece.

    本发明属于自行车结构技术领域,特别涉及一种折叠联动自锁自行车架,所述车把杆下方转向轴上部分铰接前叉上方转向轴下部分,上转向轴套管铰接转向轴上部分,转向轴套管铰接转向轴下部分,连接部二通过快拆连接轴铰接活动连接件二前端,活动连接件二后端铰接连接部三,连接部四铰接活动连接件一后端,活动连接件一前端通过快拆连接轴铰接连接部一,连动齿二与连动齿一相互啮合构成联动装置既是自锁结构锁紧车架,首管连接件上方可旋转铰接传动铰接部构成自锁结构第二部分,车座立柱铰接在连接部三上,快拆把手铰接在两个快拆连接轴一侧中间,活动连接件一上连接孔四下方铰接驱动装置。
