[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 As shown, the utility model provides the following technical solutions: a multimedia teaching device includes a shell 1, a display screen 7, a movable blackboard 10 and a filling structure, the display screen 7 and the movable blackboard 10 are both arranged in the shell 1, and the movable blackboard 10 is slidably arranged on both sides of the front end surface of the display screen 7, the filling structure is arranged between the movable blackboard 10 and the display screen 7, and the filling structure is used to fill the gap between the display screen 7 and the movable blackboard 10 and the display screen 7 and the shell 1, the filling structure includes a sliding plate 2, a movable plate 8, a second sponge strip 11 and a through hole 6, the through holes 6 are symmetrically opened at the upper and lower ends of the inner wall of the shell 1, and the through holes 6 are inserted into the inner wall of the shell 1. The length of the hole 6 is greater than the length of the display screen 7. The movable plate 8 is slidably arranged in the through hole 6, and a second sponge strip 11 is installed at the lower part of the movable plate 8 relative to one side of the movable plate 8. The end face of the second sponge strip 11 is in contact with the display screen 7. A sliding plate 2 is installed at the rear end face of the movable blackboard 10. The sliding plate 2 is flush with the movable plate 8, and both ends of the sliding plate 2 and the two ends of the bottom of the movable plate 8 are inclined. A magnetic strip 3 is symmetrically installed on the top of the movable plate 8, and a limit rod 5 is installed on the top of the inner wall of the through hole 6. Sliding grooves 4 are symmetrically opened on both sides of the movable plate 8. The limit rod 5 is embedded in the sliding groove 4, and the limit rod 5 is rectangular.

[0020] Through the above technical solution: when the teacher moves the movable blackboard 10 to open the display screen 7, the sliding plate 2 moves to both sides synchronously. After the movable blackboard 10 moves to both sides, the sliding plate 2 is out of contact with the movable plate 8, causing the movable plate 8 to slide toward the middle of the shell 1 inside the through hole 6 under the action of the suction force of the magnetic strip 3, causing the second sponge strip 11 to contact the display screen 7 embedded in the shell 1, and the second sponge strip 11 is used to block chalk dust, thereby reducing the possibility of dust entering the interior from the upper and lower ends of the display screen 7, thereby solving the problem that the current multimedia teaching device cannot effectively block chalk dust. The setting of the sliding groove 4 and the rectangular limit rod 5 prevents the movable plate 8 from detaching from the shell 1. In addition, when closing the movable blackboard 10, the end of the sliding plate 2 squeezes the end of the movable plate 8, and the inclined surfaces of the two are used to push the movable plate 8 upward, thereby ensuring the normal operation of the movable blackboard 10 and achieving the effect of rapid reset.

[0021] See also Figure 1-Figure 4As shown, the length of the movable blackboard 10 is greater than the distance between the side walls of the outer shell 1 at the end of the display screen 7, and a first sponge strip 9 is installed on the rear end face of the movable blackboard 10 and on the side close to the display screen 7, the first sponge strip 9 is located between the two sliding plates 2, and the end face of the first sponge strip 9 is in contact with the display screen 7, and fixed grooves 12 are symmetrically opened at the bottom of the movable plate 8, and the inner walls of the fixed grooves 12 are inclined outward on both sides, and the length of the fixed grooves 12 is greater than the length of the sliding plate 2, and a Velcro is arranged between the first sponge strip 9 and the movable blackboard 10, and the first sponge strip 9 and the movable blackboard 10 are adhered by the Velcro.

[0022] Through the above technical scheme: while moving the movable blackboard 10, the first sponge strip 9 moves toward the two sides of the display screen 7, and the contact between the first sponge strip 9 and the display screen 7 is used to achieve the effect of cleaning the surface of the display screen 7. After the position of the movable plate 8 is fixed, the first sponge strip 9 can fill the gaps on both sides of the display screen 7. In cooperation with the first sponge strip 9, the influence of dust on the display screen 7 is further reduced. At the same time, since the first sponge strip 9 and the movable blackboard 10 are adhered by Velcro, after multiple switches, the end of the first sponge strip 9 can be directly torn off the movable blackboard 10, and then it can be cleaned to improve the cleaning effect. The opening of the fixed groove 12 makes it possible for the sliding plate 2 to be synchronously embedded in the fixed groove 12 when the movable blackboard 10 is closed, and the interlocking connection between the sliding plate 2 and the fixed groove 12 is used to achieve the purpose of stabilizing the movable blackboard 10, thereby improving the stability of the movable blackboard 10 when the teacher is not using multimedia.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
