AI Technical Summary
There is usually only one display and placement table for existing mechanical teaching display boxes, which makes it difficult for students in the back row to clearly observe the model details. The placement table with a fixed height cannot meet the viewing needs of different students, and it takes up space when not in use, and lacks an effective storage design.
A mechanical teaching display box was designed, including two display and placement tables, one fixed at a low point and the other adjustable height, and the storage of the placement table is achieved through a moving structure. The box is cylindrical and equipped with an arc-shaped sliding door, which is convenient for the rational use of the space.
By setting up two display and placement tables to meet the needs of students of different positions and heights, ensuring that students in front and back can clearly see the mechanical model, greatly improving the viewing effect, and through the setting of the moving structure, the placement table is stored in the box when not in use, saving space.
