Description

Technical Field

[0001] This application belongs to the technical field of teaching aids storage racks, specifically an adjustable teaching aids storage rack. Background Technology

[0002] Teaching aids refer to various tools or objects used in teaching activities to assist teachers in delivering lessons and help students understand knowledge. Specifically, they include mathematical and geometric models, physical experimental devices, biological specimens, Chinese character flashcards, geographical globes, chemical experimental vessels, etc., covering a variety of auxiliary tools from basic cognition to experimental operation. These teaching aids are usually placed in different locations according to the usage scenario and needs. For example, small teaching aids commonly used in the classroom (such as chalk, rulers, and cards) will be temporarily placed on the teacher's desk, while teaching aids that need to be stored for a long time and frequently accessed (such as experimental equipment and models) will be placed together on shelves in the corner of the classroom or on storage shelves with shelves to avoid bumps and damage.

[0003] In the storage and management of teaching aids, racks or storage shelves are often used to organize and classify various teaching aids. Existing racks usually use multiple layers of fixed partitions to classify and place teaching aids to meet basic storage needs. However, fixed partitions cannot be adjusted in height according to the different sizes of teaching aids. When small teaching aids, such as flashcards or small geometric models, need to be placed, the large gaps between the partitions will lead to wasted space and cannot be fully utilized. When larger teaching aids, such as globes, need to be stored, if the gaps between the partitions are smaller than the height of the teaching aids, the only option is to remove the partitions or replace the shelves. This process is cumbersome and time-consuming, increasing the difficulty of storing and managing teaching aids and reducing the flexibility of the shelves. Therefore, an adjustable teaching aid shelf is provided. Utility Model Content
