Abstract

The invention discloses a multi-functional door column for rail vehicles. The multi-functional door column is formed by enclosing an arch surface and at least two vertical surfaces. The connecting part of the first vehicle surface and the arch surface is provided with a clamp groove, and a finger rubber strip is inserted in the clamp groove; the first vehicle surface is provided with two C-shaped grooves, and the connecting part of the first vertical surface and the second vertical surface is provided with the C-shaped groove; the top parts of the first vehicle surface and the second vertical surface are fixedly connected with the steel structure of the vehicle top; the bottoms of the first vehicle surface and the second vertical surface are fixed with the steel structure of a bottom frame; a door-side handrail installation seat is arranged at the inner part of the arch surface, and the arch surface is provided with a handrail installation hole; and a door-side handrail is fixed with the door-side handrail installation seat after being inserted in the handrail installation hole. The multi-functional door column for the rail vehicles is not a single part, but a built-in structural part of the vehicle, so that the multi-functional door column for the rail vehicles can provide the installation structure for the installation of other devices while meeting the structural needs, is capable of realizing modularization, general utilization and multi-purpose of a part and reducing the manufacturing cost of the vehicle. The multi-functional door column for the rail vehicles is skillfully constructed and conveniently and quickly installed, is simple in structure, and provides the interfaces for installation of the multiple devices.

Description

technical field [0001] The invention relates to a door column for interior decoration of a fixed side wall of a rail vehicle, and belongs to the technical field of rail vehicle interior decoration technology. Background technique [0002] At present, many subway vehicles have a built-in door structure. When installing the side wall, most of the side wall frames are connected with the car body structure, and the side wall is fixed on the side wall frame. Design is even more important. In actual production, there are many installation interfaces inside the side wall, which makes the layout of the frame inside the side wall more complex, difficult to install and position, requires a large number of fasteners during installation, low assembly efficiency, and inconvenient maintenance and repair. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rail vehicle multifunctional door post to overcome the above-mentioned de...
