Storage shelf for mathematical drawing tools

Abstract

The invention discloses a storage shelf for mathematical drawing tools. The storage shelf comprises a bottom plate, wherein a support is arranged on the inner wall of the bottom plate, the outer wallof the support is connected with the inner wall of the bottom plate, a rotating shaft is arranged on the inner wall of the support, a coupler is arranged on the outer wall of the rotating shaft, the outer wall of the coupler is connected with the inner wall of the support, and a belt sleeves the outer wall of the rotating shaft. According to the storage shelf for mathematical drawing tools, a usercan drag and pull a handle to drive rollers to move under the cooperation of the handle, a handle cover, fixed corner connectors and a pin shaft, thereby avoiding the defect of influencing use by shaking due to gaps between hinges and the multi-layer storage shelf caused by frequent opening and closing during use, and the existing storage shelf for mathematical drawing tools can be more recognized in the market, the product quality of the storage shelf for mathematical drawing tools is improved, the procurement cost of users is saved, the waste of teaching aids is avoided, and thus the storage shelf is worthy of promotion and application.

Description

Technical field [0001] The invention relates to the technical field of teaching aids, in particular to a storage rack for mathematical drawing tools. Background technique [0002] In mathematics, algebra, geometry and other subjects need to use drawing tools such as rulers, compasses, triangles, and protractors to assist in teaching. Most of the existing mathematical drawing tools are relatively simple and inconvenient to store, and they are stacked together. Mathematical drawing tools are easily damaged. Although they are used for storage of various mathematical drawing tools, the storage racks for current mathematical drawing tools have a small amount of space and cannot be classified and stored. At the same time, they are very difficult to store and take. The inconvenience in the prior art, for example, the invention patent with application number 201620139740.8 includes multiple storage racks, multiple connecting hinges, multiple movable pulleys, multiple tool hangers, multip...

Problems solved by technology

[0002] Subjects such as algebra and geometry in mathematics need to use drawing tools such as rulers, compasses, triangle rulers, and protractors to draw to assist teaching. Most of the mathematical drawing tools in the prior art are relatively single, which is inconvenient to store. Mathematical drawing tools are easily damaged. Although they are used for storing various mathematical drawing tools, the current storage racks for mathematical drawing tools have a small amount of storage space and cannot store the tools in categories. In the prior art, for example, the invention patent with application number 201620139740.8 includes multi-layer storage racks, multiple connecting hinges, multiple moving pulleys, multiple tool hanging bars, multiple partition boards, and multiple storage rack handles and a plurality of storage rack lock cores, one end face of the multi-layer storage rack is respectively connected sequentially through the plurality of connecting hinges, so that the multi-layer storage racks are sequentially arranged from front to back, and the The storage rack rotates through the connecting hinges, the plurality of moving pulleys are respectively arranged at the bottom of the multi-layer storage rack, and the plurality of storage rack handles and the plurality of storage rack lock cylinders are correspondingly arranged on the bottom of the storage rack. On the other side end surface of the multi-layer storage rack, the plurality of partition plates are respectively arranged horizontally or vertically in the multi-layer storage rack to separate the multi-layer storage rack into a plurality of storage racks. space, the plurality of tool hangers are respectively arranged in the plurality of storage spaces of the multi-layer storage rack, and the mathematical drawing tools are arranged in the multi-layer storage rack through the plurality of tool hangers, Although this invention is simple in structure, there are many deficiencies and defects. In the existing equipment, the design of the multi-layer storage rack has defects. There are gaps between the storage racks and shaking will affect the use, and the practical function of the multi-layer storage rack is single, and the storage space is small, which cannot meet the design requirements. Instructors cannot take the teaching drawing tools to the classroom at one time and need to go back and forth many times, which is easy to cause guidance. Teacher's work fatigue affects the quality of teaching. For these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a storage rack for mathematical drawing tools to overcome the defects in the prior art.
