The invention discloses a linkage mechanism and a bicycle, relates to a mechanical transmission structure, and particularly relates to a seesaw structure. Two pedals are reversely linked to drive thebicycle to move. The linkage mechanism comprises a frame, a pedal lever shaft, a rear shaft, two pedal lever, two racks, two gears, a supporting column and a shifting lever, wherein the pedal lever shaft and the rear shaft are arranged on the frame, one end of the left pedal lever is connected with the rack, the other end is connected with the pedal, the rack is meshed with the gear on the same side, the gear is connected with the rear shaft through a one-way bearing, a flat hole is formed in the end, which is connected with the pedal, of the pedal lever, the right pedal lever and parts connected with the right pedal lever are symmetrical to those on the left pedal lever, a supporting column is arranged between the two pedal lever on one side with the pedal, one end of the supporting column is fixedly connected with the frame, a cylinder is arranged at the end part of the other end of the supporting column, a hole in the middle of the shifting lever is hinged to the cylinder on the supporting column, and two ends of the shifting lever respectively penetrate through the flat holes in the left pedal lever and the right pedal lever and can slide in the two flat holes.
联动机构及其自行车,本发明涉及一种机械传动结构,尤其是指用跷跷板结构,使两个脚踏板反向联动,驱动脚踏车运动,包括:车架、踏杆轴、后轴、两个踏杆、两根齿条、两个齿轮、支柱、拨杆,踏杆轴和后轴安装在车架上,左侧踏杆的一端与齿条连接,另一端与脚踏板连接,齿条与此侧的齿轮啮合,齿轮用单向轴承与后轴连接,踏杆连接脚踏板的一端上设有扁孔,右侧踏杆及与其连接的零件都与左侧踏杆上的对称,在两个踏杆之间、有脚踏板的一边,设置有支柱,支柱的一端与车架固定连接,另一端在端部设有圆柱,拨杆中部的孔与支柱上的圆柱铰接,拨杆两端分别穿过左、右侧踏杆上的扁孔,可在这两个扁孔里滑动。
