Description

Foldable city planning model

Technical Field

The utility model relates to a display device technical field especially relates to a collapsible city planning model.

Background

In urban construction planning and display, a building sand table model is often used for visually reflecting planning schemes or combinations in the area so as to accurately express planning ideas and expected effects, but because the sand table model with a single plane can only display one idea and scheme, a planning designer cannot simultaneously display a plurality of ideas in the same sand table model, and if the planning area is large, the occupied area of the model is large, the planning details cannot be completely reflected, a viewer cannot accurately know the design ideas or ideas of the designer through the sand table model, particularly for multi-layer buildings, each layer has different design ideas, and the traditional mode is difficult to show a three-dimensional visual feeling. In the application of the prior utility model (CN201820142899.4), although a city planning model with a folding function is also provided, because the folding mode in the prior art can only be folded in the vertical direction, when we observe the sand table model, the model of top can shelter from the model of part below, and the visual field is limited, so we have designed a foldable city planning model.
