The embodiment of the invention relates to the technical field of railway vehicles, and in particular relates to a railway vehicle and a cab and a connecting base thereof. The connecting base comprises a main body bending piece, a limiting cover plate and an internal thread sliding block; the main body bending piece is provided with a fastening hole which penetrates through the thickness of the main body bending piece and is used for a fastener to penetrate through; the limiting cover plate is fixedly connected to the surface of one side of the middle of the main body bending piece, and an anti-rotation groove is formed between the limiting cover plate and the main body bending piece; an internal thread sliding block is mounted in the anti-rotation groove in a shape matching manner; the internal thread sliding block is provided with a threaded hole which corresponds to the fastening hole in position and is in threaded connection with a fastening piece. The internal thread sliding block of the connecting base is installed in the anti-rotation groove between the limiting cover plate and the main body bending piece, the internal thread sliding block can be prevented from rotating, the connecting strength is guaranteed, meanwhile, looseness prevention of the fastening piece can be achieved, and therefore potential safety hazards are completely eradicated.

    本申请实施例涉及轨道车辆技术领域,具体地,涉及一种轨道车辆及其司机室和连接座。该连接座包括主体折弯件、限位罩板以及内丝滑块;主体折弯件设置有贯穿其厚度、且用于穿设紧固件的紧固孔;限位罩板固定连接于主体折弯件的中部的一侧表面,并在限位罩板与主体折弯件之间形成防转槽;内丝滑块形状配合地安装于防转槽内;内丝滑块设置有与紧固孔位置对应且与紧固件螺纹连接的螺纹孔。该连接座的内丝滑块被安装于限位罩板和主体折弯件之间的防转槽内,能够防止内丝滑块转动,在保证连接强度的同时,还能实现紧固件的防松,从而杜绝安全隐患。
