Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to a multimedia teaching device with a transparent display screen. Background Technology

[0002] In today's era of rapid development in digital education, multimedia teaching has become an important means to improve teaching quality and enrich teaching methods. Multimedia teaching equipment with transparent displays, with its unique display effect, can present teaching content in a novel way, bringing students a more intuitive and immersive learning experience, and its application in the field of education is becoming more and more widespread.

[0003] Currently, most common transparent display multimedia teaching equipment adopts a fixed installation method. The display screen and supporting structure are often integrated, or installed using simple fixed brackets, with a lack of flexible adjustment mechanisms at the connection between the display screen and the bracket. Technically, they mainly rely on the display technology itself; for example, LED transparent screens present content through special optical and structural designs, while OLED transparent screens achieve display through their self-emissive properties.

[0004] However, this traditional equipment design has obvious drawbacks. Due to its relatively fixed angle, in actual teaching scenarios, classroom lighting conditions are complex and varied, and student seating is widely distributed. When light shines on the transparent display screen from a specific angle, it is very easy for the displayed content to be unclear, colors to be distorted, or reflections to occur. Students sitting on the sides or back of the classroom often cannot clearly see the teaching content on the screen due to the screen angle, which greatly affects the viewing experience from different positions, reduces teaching quality, and limits the full utilization of the advantages of transparent display screen multimedia teaching equipment. Therefore, a multimedia teaching device with a transparent display screen is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multimedia teaching device with a transparent display screen, which aims to improve the problem that traditional devices have a relatively fixed angle, which can easily lead to unclear display content, color distortion, or glare, affecting the viewing effect for students from different positions.

[0011] As a further description of the above technical solution:

[0012] The positioning component includes a rotating ring and a locking block. The inner wall of the rotating ring is fixedly connected to the outer wall of the rotating shaft. The rotating ring is located inside the second protective shell. The locking block engages with the inside of the rotating ring. A first connecting shell is slidably connected to the outer wall of the locking block. A push plate is fixedly connected to the top of the locking block. The outer wall of the first connecting shell is fixedly connected to the inner wall of the second protective shell. A first spring is provided inside the first connecting shell. One end of the first spring is fixedly connected to the outer wall of the locking block, and the other end of the first spring is fixedly connected to the top of the inner wall of the first connecting shell.

[0017] As a further description of the above technical solution:

[0018] Each of the connecting shells 2 has a connecting post 1 slidably connected inside, each connecting post 1 has a handle 2 fixedly connected to its top end, and each connecting post 1 has a connecting post 2 fixedly connected to its bottom end.

A bearing plate 4 is fixedly connected to the outer wall of the support frame 1, providing an installation platform for supporting other functional components. The top of the bearing plate 4... A connecting block 12 is fixedly connected to one side, which is used to connect and fix the protective shell 5 and the rotating shaft 7. A protective shell 9 is fixedly connected to the other side of the top of the bearing plate 4. The protective shell 9 is used to protect the internal adjustment and positioning components. A protective shell 5 is provided between the connecting block 12 and the protective shell 9. The protective shell 5 is used to protect the transparent display screen 6 and prevent external collisions and dust from entering. The transparent display screen 6 is fixedly connected to the inner wall of the protective shell 5. The transparent display screen 6 is used to display teaching content for students to view. An adjustment component is provided on the outer wall of the transparent display screen 6. The adjustment component is used to adjust the angle of the transparent display screen 6 to adapt to different viewing needs.

[0034] The adjustment assembly includes a rotating shaft 7, located at the bottom of the transparent display screen 6. The rotating shaft 7 supports the transparent display screen 6 and enables its rotation. The outer wall of the rotating shaft 7 is fixedly connected to the inner wall of the protective shell 1 5. Both ends of the rotating shaft 7 extend through to the outside of the protective shell 2 9 and the connecting block 12, respectively. A handle 10 is fixedly connected to one end of the rotating shaft 7 for manually rotating the shaft 7 to easily adjust the angle of the transparent display screen 6. A positioning assembly is provided on the outer wall of the rotating shaft 7 to fix its position and prevent the transparent display screen 6 from moving due to external force. A limit plate 11 is fixedly connected to the other end of the rotating shaft 7 to limit the axial movement of the rotating shaft 7 and ensure its stability. The handle 10 and the limit plate 11 are respectively fitted against the outer walls of the protective shell 2 9 and the connecting block 12. The positioning assembly includes a rotating ring 8 and a locking block 16. The inner wall of the rotating ring 8... The rotating ring 8 is fixedly connected to the outer wall of the rotating shaft 7. It is used to cooperate with the locking block 16 to position the rotating shaft 7. The rotating ring 8 is located inside the second protective shell 9. The locking block 16 is engaged with the inside of the rotating ring 8. The locking block 16 is used to fix the position of the rotating ring 8 and prevent the rotating shaft 7 from rotating accidentally. The outer wall of the locking block 16 is slidably connected to the connecting shell 13. The connecting shell 13 is used to fix the locking block 16 and guide its sliding. The top of the locking block 16 is fixedly connected to the push plate 15. The push plate 15 is used to manually operate the movement of the locking block 16. The outer wall of the connecting shell 13 is fixedly connected to the inner wall of the second protective shell 9. The connecting shell 13 is provided with a spring 14. The spring 14 is used to provide the reset force of the locking block 16 to ensure that the locking block 16 is engaged with the rotating ring 8. One end of the spring 14 is fixedly connected to the outer wall of the locking block 16, and the other end of the spring 14 is fixedly connected to the top of the inner wall of the connecting shell 13.

[0035] Reference Figure 1 and Figure 4The fixing assembly includes multiple fixed suction cup groups 25, which are used to adhere to the ground and prevent the equipment from moving. These groups are located on both sides of multiple moving wheels 3. Each fixed suction cup group 25 consists of multiple suction cups, which adhere to the ground through negative pressure to enhance the fixing effect. Connecting frames 17 are fixedly connected to both sides of the top of the chassis 2. These frames support connecting shells 18. Each connecting frame 17 has a connecting shell 18 fixedly connected inside. The connecting shell 18 accommodates and guides the movement of connecting posts 21 and 23. Each connecting shell 18 has an L-shaped groove 19 inside, which restricts the movement trajectory of the slider 20, enabling the fixing and release of the fixed suction cup groups 25. Each connecting shell 18 has a sliding connecting post 21 inside, which transmits the operating force of the handle 22, driving the connecting post 23 to move. Each connecting post 21 has a handle 22 fixedly connected to its top, which is used for manual operation. For the movement and rotation of connecting post 21, each connecting post 21 is fixedly connected to a connecting post 23 at its bottom. The connecting post 23 is used to connect and fix the suction cup assembly 25 and transmit the extrusion force. The connecting post 23 is slidably connected to the inner wall of the connecting shell 2 18. Each connecting post 21 is fixedly connected to a slide bar 20 on its outer wall. The slide bar 20 is used to slide within the L-shaped slide groove 19 to achieve the positioning of the connecting post 21. Each slide bar 20 is slidably connected to the inner wall of the L-shaped slide groove 19. The outer wall of each connecting post 23 is fixedly connected to the inner wall of the L-shaped slide groove 19. Each component is equipped with a second spring 24, which provides the restoring force for the first connecting post 21 to ensure the adsorption effect of the fixed suction cup assembly 25. One end of each second spring 24 is fixedly connected to the bottom of the inner wall of the second connecting shell 18, and the other end of each second spring 24 is in contact with the bottom of the first connecting post 21. Each second connecting post 23 is rotatably connected inside the fixed suction cup assembly 25. The rotatable connection of the second connecting post 23 ensures that the fixed suction cup assembly 25 can freely adjust its angle when adsorbing the ground, thereby improving the adsorption effect.

[0036] Working principle: During the equipment fixing process, pressing down on handle 22 causes it to move, simultaneously moving the fixed suction cup assembly 25 at the bottom of connecting column 23 to the ground via connecting column 21. This applies pressure to the suction cup assembly 25, ensuring it adheres firmly to the ground and fixing the equipment position. Simultaneously, connecting column 21 moves the slider 20 along one side of the L-shaped groove 19, compressing the spring 24. Once the suction cup assembly 25 is fully adhered to the ground, rotating handle 22 moves the slider 20 from one side of the L-shaped groove 19 to the other. Due to the spring... The top of spring 24 fits into the bottom of connecting column 21, and connecting column 23 is rotatably connected to the top of fixed suction cup assembly 25. Therefore, the rotation of connecting column 21 will not affect other components. Next, the pressure on handle 22 is released, and the rebound force of spring 24 pushes slide bar 20 to engage with the groove on the other side of L-shaped slide groove 19, fixing the position of connecting column 23. This ensures that the bottom of fixed suction cup assembly 25 is always fully adsorbed to the ground, achieving the effect of fixing the position of the equipment. This solves the problem that the equipment is prone to movement and displacement due to external collisions, requiring manual adjustment, and enhances the stability of the equipment during use.

[0037] During the angle adjustment of the transparent display screen 6, the push plate 15 is pulled, which causes the locking block 16 to slide inside the connecting shell 13 until it moves out from the inner wall of the rotating ring 8. During this process, the spring 14 is compressed by the squeezing force of the locking block 16. Next, the handle 10 is rotated to make the transparent display screen 6 rotate around the rotating shaft 7 until the transparent display screen 6 is adjusted to a suitable viewing angle for students. Then, the pushing force on the push plate 15 is released, and the rebound force of the spring 14 pushes the locking block 16 to engage with the inner wall of the rotating ring 8, thereby fixing the angle of the transparent display screen 6 on the outer wall of the rotating shaft 7. This achieves portable adjustment of the device angle, solving the problem that traditional devices have relatively fixed angles, which are prone to unclear display content, color distortion, or reflection, affecting the viewing effect of students from different positions, and enhancing the applicability of the device.
