Description

Technical Field

[0001] The utility model relates to the technical field of international trade, in particular to an international trade sandbox model. Background Art

[0002] Sand table models use miniature physical models to display architectural, military, and topographical features. They can present macroscopic model conditions as a miniature model, making it easier for everyone to understand the actual situation of the macro model. They have the advantages of a strong three-dimensional sense, intuitiveness, ease of production, and economical practicality. They are now widely used in the military and architectural fields, such as the sand table models commonly used in international trade demonstrations. When students learn about international trade, the foreign trade process is very complex and cumbersome, so sand table demonstrations are essential for teaching. Traditional sand table models generally consist of a combination of support legs and a sand table, which are fixed together using bolts or adhesives. After use, they need to be moved, meaning the user has to lift the sand table model to move it. This method is laborious and takes up a lot of space, which is inconvenient for the user.
