[0002] A sand table is a model made of mud, sand, chess pieces or other materials according to a certain proportional relationship based on topographic maps, aerial photographs or actual terrain. It is used to display areas, plans, trends or buildings. In the current exhibition industry, commonly used sand table display methods include terrain sand tables and architectural sand tables.

[0003] When displaying sand table models in existing sand table display devices, the sand table models are generally fixed in position and cannot be rotated, which makes it inconvenient for visitors at different positions to view the sand table models in all directions. At the same time, the sand table models are generally directly exposed to the outside world when idle. If they are placed for a long time, a large amount of dust may fall or the sand table models may be damaged by collision. Therefore, we propose a sand table display device to solve the above problems. Utility Model Content
