The invention provides a handrail for a rail transit vehicle, which comprises a shaft seat used for being connected with a vertical column on the rail transit vehicle; the rotating shaft assembly comprises a rotating shaft arranged on the shaft seat in a clearance sleeving mode and a shaft arm connected to the rotating shaft, and an oil pressure pipeline is arranged in the rotating shaft assembly; the rotating shaft is movably connected with the shaft seat; the pressing piece is arranged on the inner side of the rotating shaft end where the shaft arm is located; the handrail base is arranged on the shaft arm, one end of the handrail base is connected with the oil pressure pipeline, the handrail base is pressed, pressure is transmitted to the pressing piece through the oil pressure pipeline, the pressing piece is driven to extrude towards the inner side of the shaft seat, the pressing piece and the shaft seat are tightly connected in an abutting mode due to friction resistance, and the position between the rotating shaft and the shaft seat is fixed. The device has the beneficial effects that the device is used in combination with the stand column, the grabbing range of the handrail located in the doorway area is effectively expanded, a handrail rotating and stopping system is formed through an internal oil pressure pipeline, the stability of the handrail during grabbing is better guaranteed, and the riding safety of passengers is improved.
本发明提供了一种轨道交通车用扶手,包括轴座,用于与轨道交通车上立柱连接;转轴组件,包括间隙套置于所述轴座上的转轴及连接于所述转轴上的轴臂,转轴组件内设置有油压管路;所述转轴与所述轴座之间活动连接;压紧件,置于轴臂所在转轴端的内侧;扶手基座,置于所述轴臂上,扶手基座的一端与油压管路连接,按压所述扶手基座,压力经由油压管路传递至压紧件,驱动压紧件向轴座内侧挤压,使压紧件与轴座由于摩擦阻力紧密抵接实现转轴与轴座之间的位置固定。本发明的有益效果:本发明结合立柱使用,有效的扩大了位于门口区域扶手的抓扶范围,通过内部的油压管路形成了扶手的转停系统,更好的保证了扶手抓扶时的稳定性,提高了乘客的乘车安全。
