The invention relates to the field of induction stopwatches, in particular to a magnetic induction stopwatch for a bicycle, which comprises an upper clamping seat and a lower clamping seat, and the upper clamping seat and the lower clamping seat are fixedly connected to the surface of a wheel axle through a fixing bolt; the bottom end of the lifting adjusting frame is fixedly connected to the top end of the upper clamping seat; the first clamping block is fixedly connected to the top end of the lifting adjusting frame; a clamping groove is formed in the end part of the bolt, and the clamping groove is used for clamping a steel wire scroll; by arranging the upper clamping seat, the lower clamping seat, the lifting adjusting frame, the first clamping block and the second clamping block, in the riding process, the wheel axle drives the upper clamping seat and the lower clamping seat to rotate together, the lifting adjusting frame drives the first clamping block, the second clamping block and the electromagnet to rotate, and at the moment, the electromagnet is limited in the radial direction and the axial direction; therefore, the problem that the position of the electromagnet deviates in the running process of the bicycle is solved, and the success rate that the sensor captures the electromagnet is increased.

    本发明涉及感应码表领域,尤其涉及一种自行车用磁感应码表,包括:上卡座和下卡座,所述上卡座和下卡座之间通过固定栓固定连接在车轮轴表面;升降调节架,所述升降调节架的底端固定连接在上卡座的顶端;第一卡块,所述第一卡块固定连接在升降调节架顶端;螺栓,所述螺栓端部开设有卡槽,所述卡槽用于卡入钢丝条幅;本发明通过设置上卡座、下卡座、升降调节架、第一卡块和第二卡块,在骑行的过程中,车轮轴带动上卡座和下卡座一起转动,使得升降调节架带动第一卡块、第二卡块和电磁铁转动,此时电磁铁径向和轴向均被限位住,从而有利于避免自行车行驶的过程中,电磁铁的位置发生偏移的问题,有利于提高传感器捕捉到电磁铁的成功率。
