The invention relates to the technical field of rail cars and discloses a body side wall handrail fixing structure for a rail car. The structure comprises a wall body; and two mounting plates are fixedly mounted at the top of the right side of the wall body. According to the body side wall handrail fixing structure for the rail car of the invention, a threaded strip is arranged on the outer side of a vertical rod; a threaded hole matched with a rotating sleeve rod is formed in the rotating sleeve rod; the rotating sleeve rod is rotated, the rotating sleeve rod can move up and down; when a pullring needs to be disassembled and maintained, the rotating sleeve rod is rotated, so that the rotating sleeve rod moves upwards and breaks away from the limitation on a movable plate, at this moment,a compression spring pushes the movable plate to rotate through an elastic tension force by taking a rotating shaft as the axis, so that the movable plate and the rotating shaft move away from each other, and therefore, a movable clamping block is separated from a clamping groove formed in a mounting rod, at the moment, the mounting rod and the movable plate are in a separated state, the pull ring can be detached and maintained, and equipment is convenient to maintain. The body side wall handrail fixing structure for a rail car is structurally simple, is convenient to operate, and better meetthe using requirements of people.

    本发明涉及轨道车技术领域,且公开了一种轨道车用体侧墙扶手固定结构,包括墙体,所述墙体右侧的顶部固定安装有数量为两个的安装板。该轨道车用体侧墙扶手固定结构,通过在竖杆的外侧设置有螺纹条,并在转动套杆内开设有与之相适配的螺纹孔,转动转动套杆,转动套杆就会上下移动,当需要将拉环拆卸并维修时,转动转动套杆,使转动套杆向上移动并脱离对活动板的限制,此时压缩弹簧通过弹性张力力推动活动板以转轴为轴心转动并互相远离,使得活动卡块脱离安装杆所开设的卡槽,此时安装杆与活动板处于脱离状态,即可将拉环拆卸并对其维修,使设备达到便于维修的效果,结构简单并且操作方便,更加满足人们所使用的需求。
