The invention relates to the technical field of logistics transportation, aims to solve the problem of how to improve the operation efficiency of vehicle coupling, and provides a coupling device and a logistics transportation trolley. The coupling device comprises a hook piece and a traction piece. The hook piece comprises a hook base and a movable piece, the hook base is provided with a groove, the groove is provided with an opening, the hook base comprises a first inclined face and a second inclined face which are connected, and the movable piece elastically abuts against the second inclined face. The traction part comprises a traction seat and a pull ring, the pull ring is rotatably arranged on the traction seat in the vertical direction, the traction seat can be stressed and abut against the pull ring in the horizontal direction so that the pull ring can slide to the second inclined face along the first inclined face, and the pull ring abuts against the movable part to move to the position away from the second inclined face so that the pull ring can enter the groove. According to the coupling device, the traction seat is stressed to abut against the pull ring, so that the pull ring slides to the second inclined plane along the first inclined plane, the pull ring enters the groove, the pull ring is connected with the hook piece, manual operation is reduced, and the effect of improving the operation efficiency of vehicle coupling is achieved.

    本申请涉及物流运输技术领域,旨在解决如何提升车辆连挂的作业效率的问题,提供连挂装置及物流运输小车。其中,连挂装置包括钩件和牵引件。钩件包括钩座和活动件,钩座设有凹槽,凹槽具有开口,钩座包括相连的第一斜面与第二斜面,活动件弹性抵持于第二斜面。牵引件包括牵引座和拉环,拉环沿着竖直方向可转动地设于牵引座,牵引座能够受力并沿着水平方向抵持拉环使拉环沿着第一斜面滑动至第二斜面,并使拉环抵持活动件移动至远离第二斜面的位置,以使拉环进入凹槽。本实施例提供的连挂装置,牵引座受力抵持拉环使拉环沿着第一斜面滑动至第二斜面,从而拉环进入凹槽,拉环与钩件连接,因此减少手动操作,以达到提升车辆连挂的作业效率的效果。
