[0002] Multimedia is a combination of multiple media, generally including text, sound and image and other media forms. In computer systems, multimedia refers to a combination of two or more media for human-computer interactive information exchange and dissemination. With the development of science and technology, the use of multimedia in teaching is becoming more and more common, and it occupies an increasingly important position in teaching. Various schools and academic institutions are building multimedia classrooms or multi-functional halls. The media used include text, pictures, photos, sounds, animations and videos, as well as the interactive functions provided by the program, which can be used as an effective auxiliary teaching method, and can intuitively display the content to be presented, making it easier to understand. It can not only achieve the purpose of imparting knowledge, developing intelligence and cultivating abilities, but also achieve the purpose of teaching students in accordance with their aptitude and personalized teaching. Therefore, it is deeply favored by teachers, students and academic institutions. Special multimedia classrooms are built in various schools and teaching institutions. Multimedia teaching makes school teaching very convenient and practical, and has become an indispensable teaching equipment for modern teaching. Multimedia teaching devices are usually fixed on the wall. When students in the classroom play and fight during breaks, the multimedia teaching devices are easily damaged, thus affecting the use of the multimedia teaching devices. In order to better protect the multimedia teaching devices, a protective structure for the multimedia teaching devices is needed.

[0003] The existing equipment does not have anti-collision and foreign body knocking components on the front, which makes the display part of the media teaching device vulnerable to damage. Therefore, we propose a protective structure for multimedia teaching devices to solve the above problem. Utility Model Content

[0013] In the utility model, a protective structure for a multimedia teaching device is described:

[0014] 1. The utility model uses two mounting slides to guide two folding baffles to move closer to or away from each other, so as to cover the front of the multimedia or store them on both sides of the multimedia, thus significantly preventing the front from being hit by collision or foreign objects;

[0015] 2. The utility model achieves fixed connection between two folding baffles by plugging the fixed plug block into the fixed plug hole, thereby avoiding misalignment and gap at the connection, which reduces the sealing performance of the protection;

[0016] 3.
