The invention relates to the technical field of public transportation, and discloses a public bicycle locking device which comprises a right supporting disc and a left supporting disc, suspension supports are fixedly installed on the outer side of the right supporting disc and the outer side of the left supporting disc, the number of the suspension supports is two, and a rotating shaft is movablyconnected to the center of one side of the right supporting disc in a sleeving mode. Threads are formed in the bottom of the locking device and matched with threads formed in the outer surface of thethreaded sleeve. When the bicycle is ridden by a person in a locked state, a transmission system of the bicycle can drive a winch to rotate and drive a rotating shaft to rotate at the moment, so thatthe rotating shaft drives a threaded sleeve to rotate; because the bottom of the locking device engages with the threaded sleeve, the locking device moves to the right side in a picture 3 through rotation of the threaded sleeve; and when the locking device is in contact with one end of the shell, the locking device reaches the stroke limit and cannot move, so that the threaded sleeve is locked, the threaded sleeve cannot rotate, and a rear wheel of the bicycle is locked, so that the rear wheel of the bicycle cannot rotate.
本发明涉及公共交通技术领域,且公开了一种公共自行车锁定装置,包括右支撑盘和左支撑盘,右支撑盘和左支撑盘的外侧均固定安装有悬挂支架,悬挂支架的数量为两个,右支撑盘一侧的中心位置上活动套接有转轴,通过锁定器的底部开设螺纹且该螺纹与螺纹套筒外表面开设的螺纹相配合。当自行车处于锁定状态下被人骑行时,此时通过自行车的传动系统会带动绞盘进行转动并带动转轴进行转动,使得转轴带动螺纹套筒进行转动,由于锁定器的底部与螺纹套筒相互啮合,使得锁定器在螺纹套筒的转动下向图3中的右侧进行移动,当锁定器与外壳的一端相接触时锁定器达到行程极限而无法进行移动,从而将螺纹套筒锁死使其无法进行转动并锁死自行车的后轮使其无法转动。
