[0003] When visiting a sand table model, it may take a long time to observe and understand the information conveyed by the model. For complex models, it is difficult for viewers to find key information in a short time. If the angle of the sand table cannot be adjusted, the model at a distance will be blocked or the model in the sand table cannot be observed from all directions, which affects the grasp of the overall information and makes it difficult to understand the relationship and proportion between the various parts. Therefore, we propose a visual display device for economic models. Summary of the Invention

The side wall of the connecting plate is provided with a limiting groove B on the side away from the turntable, and an adjustment knob is provided for sliding in the limiting groove B. The adjusting knob passes through the limiting groove B and is threadedly connected to the limiting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The economic model visualization display device, because the height of the visitors and the sand table display may not be on the same level, the economic columnar models in the sand table are usually of different heights. When the height of the sand table is greater than the horizontal height of the visitors' field of vision when sitting down, people often find it difficult to observe the obscured columnar models, thereby reducing the efficiency of the model display. The obscured audience may find it difficult to find key information in a short time, and it is not easy to intuitively understand the relationship and proportion between the various parts, which affects the grasp of the overall information. When the moving block moves upward along the vertical direction of the reciprocating screw and the moving block drives the connecting shaft to move up to the rack, due to the meshing between the half gear and the rack, and the connection between the connecting shaft and the connecting plate, the half gear drives the connecting plate to rotate when it rotates, so that the visitors can clearly see the obscured columnar models and make full use of the limited space to display more information or content.

[0015] 2. This economic model visualization display device has a rotating shaft at the bottom of the turntable, which not only makes it convenient for visitors to observe the models placed in the sand table from multiple angles, but also makes it convenient for presenters to rotate during presentations, and point out the models that need to be presented more quickly and conveniently. After rising and tilting, it can be rotated according to the required angle, allowing visitors to observe the models more intuitively, effectively improving the efficiency of presentations and improving the limitations of traditional sand tables in content display.

[0016] 3. The economic model visualization display device effectively fixes the placement table through a circular plate to prevent the placement table from shifting due to gravity after the turntable rotates. The marking plate and the placement table are snap-fitted, making it more convenient and quick to install or remove. The snap-fit method usually causes less damage to the components during disassembly. Compared with some connection methods that require strong disassembly tools or destructive disassembly, it can better protect the integrity of the marking plate and ensure that the components can maintain good performance and appearance during multiple disassembly and installation processes.

[0028] It should be noted that when more columnar models need to be added, or the position of the placement table 6 needs to be adjusted, since there are multiple circular plates 19 on the turntable 5, the limit block fixed at the bottom of the placement table 6 for adding or replacing the position is clamped into the slide groove 18, and it is necessary to ensure that the placement table 6 and the circular plate 19 are in corresponding positions. The upper end of the circular plate 19 is close to the thread groove 21, and at this time it is rotated to connect to the columnar model 7, and the thread 22 fixed at the bottom end of the columnar model 7 is threadedly connected to the thread groove 21 inside the placement table 6. The circular plate 19 effectively fixes the placement table 6 to prevent the placement table 6 from being displaced due to gravity after the turntable 5 rotates. The marking plate 23 is clamped with the placement table 6, which makes it more convenient and quick to slide or disassemble, and the clamping method usually causes less damage to the components during disassembly. Compared with some connection methods that require strong disassembly tools or destructive disassembly, it can better protect the integrity of the marking plate 23 and ensure that the components can still maintain good performance and appearance during multiple disassembly and installation processes.

[0029] In an optional embodiment: the moving component includes a reciprocating screw 12 vertically arranged on the inner wall of the fixed column 2, a rotating motor is provided at the bottom of the reciprocating screw 12, and a moving block 13 is sleeved on the outer wall of the reciprocating screw 12, and the moving block 13 moves up and down along the outer wall of the reciprocating screw 12.

[0030] In an optional embodiment: the rotating assembly includes a connecting shaft 14 arranged on the outer wall of the moving block 13, and the connecting shaft 14 passes through the moving groove 11 and is connected to the connecting plate 3. The outer wall of the connecting shaft 14 is sleeved with a half gear 15, and the half gear 15 is engaged with the rack 10.

[0031] It should be noted that when the moving block 13 drives the connecting shaft 14 to move up to the rack 10, since the half gear 15 is engaged with the rack 10 and the connecting shaft 14 is connected to the connecting plate 3, the half gear 15 drives the connecting plate 3 to rotate when it rotates, making it easier for visitors to clearly see the obscured columnar model and make full use of the limited space to display more information or content.

[0032] In an optional embodiment, a movable groove 11 is formed on the side wall of the fixing column 2 near the connecting shaft 14 , and the movable groove 11 effectively limits the connecting shaft 14 .

[0033] It should be noted that the limit block 17 is slid until it contacts the surface of the turntable 5 , and the adjustment knob 16 is rotated to fix the position of the limit block 17 to prevent displacement.

[0034] In an optional embodiment, the thread grooves 21 provided on the inner side walls of the plurality of placement platforms 6 are located on the same horizontal line as the columnar model 7 , and the threads 22 match the thread grooves 21 .

[0035] It should be noted that the upper end of the circular plate 19 is close to the thread groove 21, and at this time it is rotated to connect to the columnar model 7. The thread 22 fixed at the bottom end of the columnar model 7 is threadedly connected to the thread groove 21 inside the placement table 6. The circular plate 19 effectively fixes the placement table 6 to prevent the placement table 6 from being displaced due to the influence of gravity after the turntable 5 rotates.

[0036] In an optional embodiment: the upper ends of multiple circular plates 19 are arranged near the thread groove 21, and springs 20 are fixed to the bottoms of the multiple circular plates 19. The surface of the turntable 5 is provided with holes that are adapted to the size of the circular plates 19, and the bottom of the spring 20 is arranged on the inner wall of the hole.

[0037] It should be noted that when more columnar models need to be added, or the position of the placement table 6 needs to be adjusted, it is necessary to ensure that the placement table 6 and the circular plate 19 are in corresponding positions, and the upper end of the circular plate 19 is close to the thread groove 21. The circular plate 19 effectively fixes the placement table 6 to prevent the placement table 6 from being displaced due to the influence of gravity after the turntable 5 rotates.

[0038] In an optional embodiment, a sliding groove 18 is provided on the top of the turntable 5 at a side close to the multiple placement platforms 6 , and the multiple placement platforms 6 slide on the turntable 5 through the sliding groove 18 .

[0039] It should be noted that when more columnar models need to be added, or the position of the placement table 6 needs to be adjusted, since multiple circular plates 19 are provided on the turntable 5, the fixed limit blocks at the bottom of the placement table 6 for adding or replacing the position can be snapped into the slide groove 18 to achieve quick replacement.

[0040] In an optional embodiment, a limiting slot A is provided on the side wall of the connecting plate 3 close to the turntable 5, and the limiting block 17 slides on the side wall of the connecting plate 3 through the limiting slot. A limiting slot B is provided on the side wall of the connecting plate 3 away from the turntable 5, and an adjusting knob 16 is provided for sliding in the limiting slot B. The adjusting knob 16 passes through the limiting slot B and is threadedly connected to the limiting block 17.

[0041] It should be noted that the limit block 17 is slid until it contacts the surface of the turntable 5 , and the adjustment knob 16 is rotated to fix the position of the limit block 17 to prevent displacement, so that the limit block 17 effectively fixes the turntable 5 .

[0042] Working principle: when the exhibition staff needs to move the booth, they hold the push handle 8 and push the entire sand table booth to the position where the exhibition is required. Since the height of the visitors and the sand table display may not be on the same level, the economic column models in the sand table are usually of different heights. When the height of the sand table is greater than the horizontal height of the visitors' field of vision when they sit down to watch, it is often difficult for people to observe the obscured column models, thereby reducing the efficiency of the model display. Due to the obstruction, the audience may find it difficult to find key information in a short time, and it is not easy to intuitively understand the relationship and proportion between the various parts, which affects the grasp of the overall information. First, slide the limit block 17 Until it fits the surface of the turntable 5, the adjusting knob 16 is rotated to fix the position of the limit block 17 to prevent displacement. At this time, the limit block 17 effectively fixes the turntable 5, and the reciprocating screw 12 in the fixed column 2 is started. The moving block 13 moves upward along the direction perpendicular to the reciprocating screw 12. When the moving block 13 drives the connecting shaft 14 to move up to the rack 10, since the half gear 15 is engaged with the rack 10 and the connecting shaft 14 is connected to the connecting plate 3, the half gear 15 drives the connecting plate 3 to rotate when it rotates, so that the visitors can clearly see the obscured columnar model and make full use of the limited space to display more information or content.

[0043] A rotating shaft is provided at the bottom of the turntable 5, which not only makes it convenient for visitors to observe the models placed in the sand table from multiple angles, but also makes it convenient for the exhibitor to rotate it during a presentation, and point out the model that needs to be presented more quickly and conveniently. After rising and tilting, it can be rotated according to the required angle, allowing visitors to observe the model more intuitively, effectively improving the efficiency of the presentation and improving the limitations of traditional sand tables in content presentation.

[0044] When more columnar models need to be added or the position of the placement table 6 needs to be adjusted, since there are multiple circular plates 19 on the turntable 5, the limit block fixed at the bottom of the placement table 6 to be added or replaced is clamped into the slide groove 18, and it is necessary to ensure that the placement table 6 and the circular plate 19 are in corresponding positions. The upper end of the circular plate 19 is close to the thread groove 21. At this time, it is rotated to connect the columnar model 7, and the thread 22 fixed at the bottom end of the columnar model 7 is threadedly connected to the thread groove 21 inside the placement table 6. The circular plate 19 effectively fixes the placement table 6 to prevent the placement table 6 from being displaced due to gravity after the turntable 5 rotates. The marking plate 23 is clamped with the placement table 6, which makes it more convenient and quick to slide or disassemble, and the clamping method usually causes less damage to the components during disassembly. Compared with some connection methods that require strong disassembly tools or destructive disassembly, it can better protect the integrity of the marking plate 23, ensuring that the components can still maintain good performance and appearance during multiple disassembly and installation processes.

[0045] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
