Abstract

The invention discloses a top connecting structure of a middle column handrail of urban rail and subway vehicles. A T-shaped groove bolt is fixed to a ceiling section material of the vehicles through a nut and a lock washer, threads at the lower part of the bolt penetrate through a middle roof plate of the vehicles to be screwed into a connecting base with internal threads, the connecting base is of a T shape structure, external threads are arranged at the upper part of the connecting base, the lower part of the connecting base is inserted into the top of the middle column handrail and is fixed, and a decorative cover with internal threads is matched with the connecting base with the external threads and can cover a round hole in the middle roof plate. According to the top connecting structure, connection of the handrail is firm, shaking in all directions is limited, the decorative cover can be installed on the outer surface of the middle roof plate of the vehicles easily, unattractiveness caused by non-uniform gaps is effectively avoided, the structure is simplified, the machining processes are reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of urban rail vehicles, and in particular relates to a connection structure at the top of a column armrest in an urban rail subway vehicle. Background technique [0002] During the operation of urban rail vehicles, most of the passengers need to stand and ride, so most of the vehicles are equipped with center column handrails, so the reliability and aesthetics of the center column handrails are very important. The upper connection of the central column handrail adopted in most domestic urban rail vehicles is to insert the decorative cover into the middle roof of the vehicle and fix the top of the central column handrail by the decorative cover. When installing the top of the existing center pillar armrest, a round hole matching the size of the decorative cover needs to be opened on the center roof of the vehicle. There is a boss at the center of the top cover, and the top cover is pressed against the tube w...
