[0002] Projection screen, also known as projection screen, is a tool used to display images and video files in movies, offices, home theaters, large conferences and other occasions. It can be generally divided into commercial screens, home screens, engineering screens, etc. according to the usage scenarios.

[0003] At present, due to some special usage requirements, projection screens are no longer completely limited to indoor use, and projection screens are often used for projection outdoors or in some open environments. Existing projection screens are usually fixed on the wall. When encountering some scenes where the screen needs to be replaced or cleaned, it is very inconvenient to disassemble and assemble. In addition, when using the projection screen outdoors or in some open environments, it is inevitably affected by wind. Since the projection screen in the prior art is usually only suitable for indoor environments, its stability is poor. When used in an open environment, it is easy to produce a large degree of shaking under the influence of wind, which seriously affects the user's use and viewing experience. Utility Model Content

[0004] In view of the above-mentioned problems, the utility model provides a projection screen installation structure which is easy to assemble and disassemble, has strong stability and provides a good user experience.
