Through the settings of the display table, universal wheels, storage box, motor, coupling, lead screw, nut support, back plate, display screen, magnetic levitation mechanism, magnetic levitation base, control board, Hall sensor, permanent magnet, electromagnet, storage battery, magnetic levitation cover plate and float, during use, the display screen can play details about the processing technology of acrylic and the characteristics of acrylic plates. The float rotates at a determined position, enabling customers to see each side of the acrylic plate inserted in the card slot. The display method is novel and helps customers better understand the exhibits.

[0004] However, when the existing acrylic plate display racks are in use, there are the following two problems:

[0005] First, although a simple acrylic plate display rack can support the acrylic plate, the support is not stable, which easily leads to the problem of the acrylic plate falling and being damaged. Second, although a reinforced acrylic plate display rack can reinforce the acrylic plate, it increases the production cost and is not flexible in use. Therefore, how to prevent the acrylic plate from falling and being damaged while achieving the effect of flexible use is an urgent problem to be solved. Content of the Utility Model

[0006] The purpose of the utility model is to provide an acrylic plate display rack for preventing falling and damage, which has the effect of preventing the acrylic plate from falling and being damaged while achieving flexible use.
