[0002] Multimedia teaching refers to the process of teaching, according to the characteristics of teaching objectives and teaching objects, through teaching design, the rational selection and use of modern teaching media, and the organic combination with traditional teaching methods, jointly participating in the whole teaching process, using a variety of media information to act on students, forming a reasonable teaching process structure, and achieving the best teaching effect. In the current education process, smart displays have gradually been used in classrooms instead of projections, which have better clarity and can be operated more conveniently.

[0003] The current display is placed in the corner of the classroom using a bracket. Since the bracket has a certain height, it will make the display inconvenient to operate and the display will be easily damaged. In order to solve this problem, some classrooms will embed the display inside the sliding blackboard, but the existing sliding blackboards are mostly set on different surfaces, resulting in a certain blind spot, and at the same time will cause a certain impact on the blackboard writing. Therefore, in order to solve the above problems, the present application provides a hidden pull-out teaching display.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 - Figure 8 This application is described in further detail.

[0029] Example 1: Reference Figure 1 - Figure 8 A hidden pull-out teaching display 6 includes a frame 1, both sides of the frame 1 are fixedly connected with side panels 2, and a movable panel 3 is slidably embedded between the side panels 2, and a display 6 is arranged behind the movable panel 3, and a slide groove 4 for the movable panel 3 to slide is opened on the frame 1, and an inclined groove 41 is integrally formed on the slide groove 4, and the inclined groove 41 changes the plane position of the movable panel 3;

[0030] Connecting pieces 9 are welded to the upper and lower sides of the movable plate 3 near the corners, and a pin 11 is welded to the side of the connecting piece 9 facing the frame 1. The pin 11 cooperates with the slide groove 4 and the inclined groove 41. The slide groove 4 is horizontally arranged, and the inclined groove 41 is inclined toward the back of the frame 1, and the inclined direction of the inclined groove 41 is the same as the sliding direction of the movable plate 3. The setting of the inclined groove 41 makes it possible for the movable plate 3 to operate toward the front side of the side plate 2 and then move horizontally when the pin 11 slides from its inner side into the slide groove 4, thereby avoiding contact between the movable plate 3 and the side plate 2 and ensuring the normal sliding of the movable plate 3. The setting of the inclined groove 72 ensures that the movable plate 3 moves inward after being reset, thereby ensuring that its plane and the side plate 2 are displaced in the same plane, reducing the occurrence of skewness between them.

[0031] A driving rod 10 is welded to the upper and lower sides of one side of the movable plate 3, and a pin shaft 11 is welded to the end of the driving rod 10;

[0032] The upper and lower sides of the display 6 are fixedly connected with the slide bar 7 by bolts, and the slide bar 7 is provided with a second slide groove 71 and a second inclined groove 72 which cooperate with the pin shaft 11 of the driving rod 10. The movable plate 3 slides to the side position, and the pin shaft 11 pushes the display 6 to move in a direction perpendicular to the surface of the movable plate 3. One end of the second slide groove 71 passes through the end of the slide bar 7, and the other end is connected with the second inclined groove 72. The distance of the second inclined groove 72 in the direction perpendicular to the surface of the movable plate 3 is greater than the distance between the initial position of the display 6 and the surface of the side plate 2. The second inclined groove 72 is arranged toward the rear of the frame 1, and the inclination direction of the second inclined groove 72 is opposite to the sliding direction of the driving rod 10. The driving rod 10 is arranged in a vertical direction, and the driving The pin shaft 11 at the end of the rod 10 is spaced apart from the second slide groove 71. The top end of the driving rod 10 is welded to the top end of the movable plate 3 through the second connecting piece 13. The second connecting piece 13 ensures that when the movable plate 3 slides into place, the pin shaft 11 is located in the second inclined groove 72 and pushes the display 6 to a position flush with the end surface of the movable plate 3. The pin shaft 11 at the end of the driving rod 10 and the second slide groove 71 are spaced apart so that when the movable plate 3 slides outward, it will move outward by a distance that is the same as the spacing between the pin shaft 11 at the end of the driving rod 10 and the second slide groove 71, thereby ensuring that the pin shaft 11 can slide to the inner side of the second slide groove 71 and finally slide into the second inclined groove 72 through the second slide groove 71.

[0033] A plurality of slide rods 12 are fixedly connected to both horizontal sides of the display 6, and the outer sliding sleeve of the slide rod 12 has a slide rail 8, the slide rail 8 is fixedly connected to the external structure by bolts, and the slide rail 8 is fixedly connected to the external wall by bolts, so that when the pin shaft 11 slides in the second inclined groove 72, the display 6 will slide forward in the slide rail 8 through the slide rod 12, thereby ensuring the stability of the display 6 sliding forward.

[0034] A plurality of fixing brackets 5 are provided on the back of the side panel 2, and the fixing brackets 5 are fixedly connected to the side panel 2 and the frame 1 by bolts. The upper and lower sides of the side panel 2 are matched with the gap between the frame 1, and the width of the gap is greater than the thickness of the connecting piece 1 9 and the connecting piece 2 13. The upper and lower gaps of the side panel 2 are used for the sliding of the connecting piece 1 9 and the connecting piece 2 13, thereby ensuring that the side panel 2 can slide to one side and at the same time ensure the position control of the inner display 6.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
