[0002] A sand table usually refers to a three-dimensional model that is scaled down and physically reproduces the terrain, architecture or urban layout of a specific area. Sand tables can be made of various materials, such as sand, soil, plastic, wood or more advanced synthetic materials. They are widely used in many fields. The electronic display sand table of the science and technology museum is a highly interactive and informative display method designed to educate and entertain the audience. It is usually used to explain complex scientific concepts, geographic information, urban development, historical events or future visions.

[0003] Ordinary display sand tables can only display static models. Viewers can only view one side of the model when they are in a fixed position. Viewers need to move their positions, and the model cannot be displayed from multiple angles. The electronic display sand table of the science and technology museum must meet the demand for all-round display of the model. The automatically rotating electronic display sand table of the science and technology museum can provide a vivid, intuitive and interactive display experience, effectively attract the audience's attention, and enhance the educational and entertainment value.

[0004] Therefore, we need to design an electronic display sandbox for the science and technology museum that can rotate automatically. Utility Model Content

The turntable 5 is connected to the output end of the motor Ⅰ4, and the turntable 5 is located in the lower part of the lifting block 3. The turntable 5 is driven to rotate by the output end of the motor Ⅰ4, so that the exhibits placed on the turntable 5 are rotated.

[0023] like Figure 2-Figure 3As shown, it also includes a motor II 6, a screw rod I 7, a fixing block 8, a first guide rod 9 and a support rod I 10. The motor II 6 is installed on the right side of the bottom of the box body 2 by bolts, and the screw rod I 7 is connected to the output end of the motor II 6. The upper end of the screw I 7 is threadedly connected to the right side of the lifting block 3. The fixing block 8 is connected to the lower left side of the box body 2. The top of the fixing block 8 is connected to the first guide rod 9. The top of the first guide rod 9 is slidably connected to the other side of the lifting block 3. A support rod 10 is connected between the first guide rod 9 and the screw I 7. Rod Ⅰ10, the left side of the support rod Ⅰ10 is slidably connected to the first guide rod 9, the right side of the support rod Ⅰ10 is threadedly connected to the screw rod Ⅰ7, and the middle part of the support rod Ⅰ10 is connected to the outer side of the lower part of the motor Ⅱ6. The motor Ⅱ6 drives the output shaft to drive the screw to rotate and make the support rod Ⅰ10 cooperate with its thread, and slide along the first guide rod 9 into the box body 2, so that the motor Ⅰ4 and the turntable and lifting platform 3 connected thereto slide into the box body 2 together, so that the exhibits placed on the turntable 5 can be stored in the box body 2.

[0024] like Figure 2-Figure 3 As shown, it also includes a buffer block 11 and a return spring 12. Four buffer blocks 11 are symmetrically slidably connected inside the lifting block 3 along the circumferential direction. The two ends of the four buffer blocks 11 extend to the top and bottom of the lifting block 3 respectively, and the diameters of the two ends of the four buffer blocks 11 are wider than the middle diameter of themselves. The return spring 12 is connected between the top of the lifting block 3 and the middle of the four buffer blocks 11. When the exhibit is placed on the turntable 5 and contacts the four buffer blocks 11, the return spring 12 is deformed and compressed by force to reduce the shock of the exhibit.

[0025] like Figure 1 and Figure 4 As shown, it also includes a second guide rod 13, a support rod II 131, a motor III 14, a screw II 15 and a cover plate 16. The second guide rod 13 is connected to the right side of the top of the box body 2, and the support rod II 131 is connected to the top of the second guide rod 13. The motor III 14 is installed on the left side of the support rod II 131. The output shaft end of the motor III 14 is connected to the screw II 15. The bottom of the screw II 15 is threadedly connected to the left side of the top of the box body 2. The second guide rod 13 and the screw II 15 are at the same vertical parallel height. A cover plate 16 is connected between the screw II and the second guide rod 13. The right side of the cover plate 16 is slidably connected to the second guide rod 13, and the left side of the cover plate 16 is threadedly connected to the screw II 15. The outer contour of the middle part of the cover plate 16 is consistent with the outer contour of the lifting block 3. After the cover plate 16 rotates through the screw II 15 and cooperates with its thread to slide down along the second guide rod 13 until the cover plate 16 can contact the top of the box body 2, a closed cavity can be formed inside the box body 2.

[0026] like Figure 4 As shown, lighting lamps 17 are also included. Six lighting lamps 17 are connected to the bottom of the cover plate 16. The lighting lamps 17 can illuminate the exhibits to fully display the detailed beauty of the exhibits.

[0027] Before using the device, the device should be placed on a horizontal ground. If the cover plate 16 is at the top of the lifting block 3, the motor III 14 should be started through the controller first to drive the screw rod II 15 to rotate. Since the screw rod II 15 is threadedly matched with the right side of the support rod II 131, the second guide rod 13 is slidably matched with the support rod II 131 on the left side, thereby driving the cover plate 16 to move vertically upward until the cover plate 16 moves to a suitable position. Then the motor II 6 is started through the controller, and the output shaft of the motor II 6 drives the screw rod I 7 to rotate. Since the support rod I 10 is connected between the first guide rod 9 and the screw rod I 7, the first guide rod 9 is slidably matched with the left side of the support rod I 10, and the screw rod I 7 is threadedly matched with the right side of the support rod I 10, so the support rod I 10 moves vertically upward with the lifting block 3, the motor I 4 and the turntable 5 until the lifting block 3 When the top of the sand table model contacts the top of the first guide rod 9 and the screw rod Ⅰ7, the motor Ⅰ4 is turned off by the controller, and then the sand table model is placed on the top of the turntable 5. Before the sand table model contacts the turntable 5, the buffer block 11 moves downward due to the interaction inside, and the return spring 12 is compressed. After the sand table model is placed stably, if the brightness of the exhibition hall lighting is insufficient, the lighting lamp 17 needs to be turned on by the controller. After the display is completed, the motor Ⅰ4 should be turned off first, and then the motor Ⅱ6 should be started again. Since the first guide rod 9 and the left side of the support rod Ⅰ10 are slidably matched, and the screw rod Ⅰ7 and the right side of the support rod Ⅰ10 are threadedly matched, the support rod Ⅰ10 moves vertically downward with the lifting block 3, the motor Ⅰ4 and the turntable 5. Finally, the lighting lamp 17 is turned off by the controller, and then the motor Ⅲ14 is started, and the cover plate 16 moves vertically downward and the cover plate 16 is closed.

[0028] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
