The limiting plates 6 can limit the sliding range of the protective plates 4 to ensure that they will not fall off the track during the sliding process, thereby ensuring the stability and safety of the equipment.

[0034] A drive assembly, which propels the sliding components, is fixedly connected to the top of the inner wall of the blackboard 2. This drive assembly plays a key role in the entire device, providing power to secure the multimedia housing 16. The drive assembly includes a cylinder 7. Its top side is securely attached to the top of the inner wall of the blackboard 2, ensuring it does not loosen during operation. An upper slide 8 is fixedly connected to the drive end of the cylinder 7. Driven by the cylinder 7, the upper slide 8 slides smoothly. Two guide rods 10 are fixedly connected to the inner wall of the blackboard 2. These straight and sturdy guide rods 10 provide precise guidance for the upper and lower slides 8 and 9, ensuring they do not deviate from their directions during movement. The lower slide 9 is slidably connected to the outer portions of the two guide rods 10. The lower slide 9 and the upper slide 8 work together to secure the multimedia housing 16. Two open plates 11 are fixedly connected to the side of the lower slide 9 closest to the drive assembly. These open plates 11 provide support points for the rotation of the rotating plate 12. The left and right ends of the upper slide 8 are slidably connected to the outer portions of the two guide rods 10. This design enables the upper slide plate 8 to slide smoothly on the guide rod 10, ensuring the smooth operation of the equipment;

[0035] The far sides of the strip plates 14 are fixedly connected to the middle portions of the proximal sides of the two guide rods 10. The strip plates 14 serve as a connection and support, ensuring the stability of the guide rods 10. The left and right ends of the bottom side of the upper slide 8 are fixedly connected to the top sides of two of the opening plates 11. This connection allows the upper slide 8 to move the opening plates 11 together. The opening plates 11 are rotatably connected to the interiors of the opening plates 11. The rotating plates 12 are flexible and can rotate freely within the opening plates 11, providing transmission for the movement of the I-shaped plates 13. Each of the two rotating plates 12 is rotatably connected to an I-shaped plate 13 at its proximal end. The inner walls of the two I-shaped plates 13 are slidably connected to the strip plates 14. The strip plates 14 ensure the accuracy of the movement of the I-shaped plates 13. A clamping block 15 is fixedly connected to the rear side of the multimedia housing 16. The clamping block 15 is securely fixed to the multimedia housing 16 and cooperates with the upper and lower slides 8 and 9 to stably clamp and secure the multimedia housing 16. The adjacent sides of the upper slide plate 8 and the lower slide plate 9 are in contact with the upper and lower sides of the clamping block 15. This contact mode ensures stability and reliability when the multimedia housing 16 is pushed.

[0036] Reference Figures 3 to 6 Sliding plates 17 are slidably connected to both ends of the blackboard 2. The sliding plates 17 can slide smoothly on the blackboard 2, providing support for the movement of subsequent components. A reset assembly is fixedly connected to the top inner wall of the sliding plate 17, which restricts the sliding plate 17. This reset assembly restores the sliding plate 17 to its original position after movement, ensuring normal operation of the device. The reset assembly includes a spring 18. The spring 18 has a certain degree of elasticity, and its bottom end is firmly fixed to the top inner wall of the sliding plate 17. It can deform when subjected to external forces, storing energy. A curved column 19 is fixedly connected to the top of the spring 18. The curved column 19 has a unique shape that can cooperate with the curved opening 20 in the wall 1 to limit and secure the sliding plate 17. Multiple curved openings 20 are provided on both ends of the wall 1. The design of the curved openings 20 perfectly matches the curved columns 19, providing multiple options for positioning the sliding plate 17. The outer portions of the two curved columns 19 are slidably connected to the left and right ends of the top of the blackboard 2, respectively. This connection method enables the arc-shaped column 19 to slide smoothly on the blackboard 2 and cooperate with the arc-shaped opening 20;

[0037] A connecting post 21 is fixedly connected to the bottom side of the sliding plate 17. The connecting post 21 connects the sliding plate 17 to the connecting plate 22, transmitting force. A connecting plate 22 is fixedly connected to the bottom side of the connecting post 21. The connecting plate 22 is large in area, providing stable support for the push post 23. A push post 23 is fixedly connected to the bottom side of the connecting plate 22. The push post 23 is straight and sturdy, able to slide within the inclined opening 25 of the load-bearing plate 24, pushing the load-bearing plate 24 to move. The outside of the push post 23 is slidably connected to the load-bearing plate 24. The inclined opening 25 inside the load-bearing plate 24 is uniquely designed and can cooperate with the push post 23 to achieve a specific motion trajectory. The inclined opening 25 inside the load-bearing plate 24 enables the push post 23 to generate a specific force direction during the sliding process. A storage box 26 is fixedly connected to the outside of the load-bearing plate 24. The storage box 26 can be used to store teaching supplies or other items, providing convenience for teaching. Support plates 27 are fixedly connected to the front and back sides of the storage box 26. The support plates 27 provide support and guidance for the sliding movement of the storage box 26. The outer portion of each of the two support plates 27 is slidably connected to the outer portion of one of the right-angle plates 28. The right-angle plates 28 provide a track for the sliding movement of the support plates 27. The right-angle plates 28 are fixedly connected to the front and back ends of the bottom side of the blackboard 2. The right-angle plates 28 are firmly fixed to the blackboard 2, ensuring the stability of the movement of the storage box 26.

[0038] Working Principle: By pulling the pull plate 5, the protective plate 4 slides, exposing the interior of the blackboard 2. The clamping block 15 on the exterior of the multimedia housing 16 is then placed above the lower slide 9, which then activates the cylinder 7 in the drive assembly. The drive end of the cylinder 7 pushes the upper slide 8 upward along the two guide rods 10 on the inner wall of the blackboard 2. As the upper slide 8 slides, the opening plates 11 connected to its left and right ends on the bottom side also move. The rotating plate 12, which is rotatably connected to the opening plate 11, begins to rotate, driving the I-shaped plates 13 rotatably connected to it. Because the inner walls of the two I-shaped plates 13 are slidably connected to the strip plates 14, which are fixed between the two guide rods 10, the movement of the I-shaped plates 13 is restricted. Through the linkage of the opening plates 11, the rotating plate 12, and the I-shaped plates 13, the upper and lower slides 8 and 9 clamp the clamping block 15 on the rear side of the multimedia housing 16 and push it upward. In this way, the installation and disassembly of the multimedia housing 16 can be completed quickly, thereby facilitating the maintenance of the multimedia housing 16 and improving the maintenance efficiency.

[0039] At the same time, when the teaching supplies or items in storage box 26 need to be accessed, this can be achieved by pushing sliding plate 17. When sliding plate 17 is pushed, curved posts 19 connected to springs 18 on the inner wall of the top of sliding plate 17 slide out of curved opening 20 in wall 1. Connecting posts 21 on the bottom of sliding plate 17 drive connecting plate 22 to move, and push posts 23 on the bottom of connecting plate 22 slide in inclined opening 25 within load-bearing plate 24. Due to the special design of inclined opening 25, the sliding of push posts 23 generates a horizontal force component, pushing load-bearing plate 24 and storage box 26 fixed to it. The support plates 27 on the front and rear sides of the storage box 26 slide outside the right-angle plates 28 at the front and rear ends of the bottom side of the blackboard 2, so that the educational tools inside the right-angle plates 28 can be presented for easy taking, thereby improving the utilization of space; at the same time, the sliding plate 17 is pulled out and engaged with the inside of the arc-shaped opening 20 through the arc column 19, so that the two ends of the blackboard 2 can be blocked, so that light cannot be reflected on the surface of the blackboard 2, which affects teaching, thereby improving the quality of teaching.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
