The invention provides a passenger seat armrest rotating device of a small highway passenger car. The passenger seat armrest rotating device comprises a rotating armrest, a disc and positioning shafts, wherein a center hole is formed in the bottom end of the rotating armrest, and two sets of rail grooves are formed in the center hole in an up-down alignment mode; the disc is fixedly connected witha fixing shaft, and the fixing shaft penetrates through the center hole to be connected with a seat back through bolts; two sets of positioning shafts are arranged in an aligned mode and fixedly connected with lifting handles, and the positioning shafts penetrate through the rail grooves to be connected with the seat back through bolts. According to the invention, two sets of rail grooves are formed in the rotating armrest in an aligned mode, a groove is formed in one end of the rail groove, and the rotating armrest can rotate around the fixing shaft by 90 degrees; when the rotating armrest is located at the highest point, the positioning shafts are moved downwards to the bottom ends of the grooves, the two positioning shafts are clamped in the grooves of the two rail grooves, and the rotating armrest is fixed; and the two sets of positioning shafts are fixedly connected with the handles, the handles can be pulled to control the two sets of positioning shafts to ascend or descend at the same time, and the operation is easy.

    本发明提供一种小型公路客车乘客座椅扶手旋转装置,包括旋转扶手,圆盘和定位轴;所述旋转扶手底端设有中心孔,且中心孔上下对位设有两组轨道槽;所述圆盘与固定轴固定连接,且固定轴穿过中心孔与椅背螺栓连接;所述定位轴对位设有两组,并与提手固定连接,且定位轴贯穿轨道槽与椅背螺栓连接。本发明通过旋转扶手上对位设有两组轨道槽,轨道槽的一端设有凹槽,使得旋转扶手可以围绕固定轴做90°的旋转,当旋转扶手处于最高点位置的时候,将定位轴向下移动到凹槽的底端,两个定位轴卡装在两个轨道槽的凹槽中,实现了对旋转扶手的固定,并且两组定位轴均与提手固定连接,使得拉动提手能够控制两组定位轴同时上升或者下降,操作简单。
