[0001] The utility model belongs to the technical field of televisions, and more specifically, it particularly relates to a subway passenger compartment television for playing videos. Background Art
[0002] With the progress of technology and the continuous development of society, the continuous optimization and improvement of televisions enable people to simply and intuitively obtain information from all over the country. The installation scope of televisions is also increasing, especially on means of transportation such as buses and subways. Therefore, it can be seen that the televisions currently used in subways basically meet people's needs, but there are still some problems.
[0003] Based on the above, the inventor found the following problems: Firstly, the television is located on the subway. The subway is often in a place where it is running and has a large flow of people. The high-frequency vibration and external high-frequency touches cause the television to be easily damaged and often need to be repaired. Most of the existing televisions are fixed inside the subway by bolts, and a large amount of time is required for disassembly. Secondly, the television needs to be located in a more prominent position inside the subway for passengers to watch, resulting in the television in the subway passenger compartment not being too high. People come and go and pass by the television frequently, and the television screen is relatively fragile and easily damaged by external touches.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a subway passenger compartment television for playing videos is provided, in order to achieve a more practical and valuable purpose. Content of the Utility Model
