Description

Technical Field

[0001] The utility model relates to the technical field of subway carriage seat screens, in particular to an adjustable subway carriage seat screen. Background Art

[0002] The subway is a fast, high-capacity, electric-powered rail transit system built in the city. The trains run on fully enclosed lines. The lines in the central city are basically located in underground tunnels, and the lines outside the central city are generally located on viaducts or on the ground. The subway is a high-density, high-capacity urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas. At the same time, the advantage of the subway is its large capacity. Therefore, in order to accommodate more people in the subway car, only a small number of seats are designed in the subway car. Generally, long strips of seats are set on both sides of each car for easy riding, and baffles are generally set at both ends of the seats to act as screens and partitions.

[0003] At present, most of the existing subway car seat screens need to be fixed at multiple points, which makes installation and removal more troublesome. At the same time, the subway car seat screens have a single function and cannot effectively and reasonably utilize the space on the screen, reducing the practicality and comfort of the subway car seats.

[0004] Therefore, in view of the above problems, we propose an adjustable subway car screen to solve the above problems. Utility Model Content
