Description

Technical Field

[0001] This utility model relates to the field of teaching device technology, specifically a support device for teaching aids. Background Technology

[0002] Financial mathematics, also known as mathematical finance, mathematical finance, or analytical finance, uses mathematical tools to study finance. It involves quantitative analysis such as mathematical modeling, theoretical analysis, and numerical calculations to find the inherent laws of finance and use them to guide practice. Economic analysis can be divided into macroeconomic analysis and microeconomic analysis according to the scope of the analysis object. The analyzed information needs to be displayed, such as drawing economic trend curves and explaining key nodes and turning points. Existing teaching devices for analyzing economic information use magnetic glass whiteboards, which consist of a stand and a glass whiteboard. They can be written on and projected, and are equipped with magnetic blocks to fix the drawings, making it convenient to display the analyzed economic information.

[0003] A search revealed a Chinese utility model patent with publication number CN221486003U, which discloses a teaching aid. The general description includes a board body with a frame on its exterior. A support plate is fixedly connected to the bottom of the board body, and a magnet block holder is fixedly mounted on the support plate. In use, this teaching aid utilizes a push rod. When a magnet block is needed, pushing the push rod upwards causes one end of the rod to press against the magnet block until it is pushed out of the holder, facilitating retrieval by the teacher. Afterwards, a spring returns the push rod to its original position, and the magnet block is then returned to its original position. The retractable placement slot allows for the storage of magnetic blocks, which facilitates storage and prevents them from easily falling out. However, the device still has some shortcomings. For example, it does not protect the board, and dust may accumulate on it when it is not in use or when it is moved, which may cause damage. Furthermore, the device does not allow for height adjustment of the board, making it unsuitable for different teachers and students to use for teaching or viewing. Therefore, it is not very practical. To address these issues, we propose a support device for teaching aids. Utility Model Content

[0040] In summary, the working principle and process of this teaching aid support device are as follows: First, place the support device at the desired location and connect the motor 9 to the forward and reverse circuits according to the instruction manual. Then, slide the control block 18, causing it to drive the slider 16 to compress the spring 17. The slider 16 moves out of the limit port 26. At this point, the handle can be used to pull the protective groove 6. During this process, the multi-section telescopic rod 4 will also extend and retract accordingly. Then, move the protective groove 6 above the two lifting columns 12, so that the positioning block 1... 5. Enter the positioning groove 25, so that the protective groove 6 is limited on the lifting column 12. At this time, start the motor 9. The motor 9 will drive the rotating shaft 8 and the gear 10 to rotate. The gear 10 will drive the gear 2 14 to rotate. The gear 2 14 will drive the threaded shaft 13 to rotate. Then the threaded shaft 13 cooperates with the lifting groove 11, forcing the threaded lifting column 12 to rise. This will allow the magnetic glass whiteboard 7 to be height adjusted, making it convenient for teachers and students to use. At this time, the teacher can pull out the placement groove 19 to use the magnetic blocks, pens, etc. placed in the placement groove 19.

[0041] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent.
