Description

Technical Field

[0001] This invention belongs to the field of teaching aids technology, specifically referring to a mathematical geometric figure folding teaching aid. Background Technology

[0002] Mathematical geometry is a fundamental part of mathematics, involving the study of basic concepts such as points, lines, planes, and solids, as well as the relationships between them in terms of position, size, and shape. These geometric figures are not only an important component of mathematical theory but also powerful tools for solving practical problems, and are widely used in fields such as engineering, architecture, physics, and computer graphics.

[0003] However, in current teaching practice, traditional geometric manipulatives are often single-function, only meeting specific teaching needs. For example, some manipulatives can only be used to draw circles or straight lines, while others can only be used to display specific geometric shapes. This single-function design forces teachers to frequently change different manipulatives to adapt to different teaching content and stages. This not only increases the burden of lesson preparation and teaching for teachers but also affects the continuity of teaching and students' comprehension. Summary of the Invention

[0032] The angle determining component 35 includes a first disk 37, a second disk 38, a third connecting shaft 39, a suction cup 40, side posts 41, a third scale line 42, an angle scale line 43, a rubber band 44, and a central shaft 52. One side of the first disk 37 is fixedly connected to one end of the third connecting shaft 39, and the other end of the third connecting shaft 39 is fixedly connected to one side of the second disk 38.

[0033] The arc marking assembly 36 includes a sleeve 45, a third storage cavity 46, a first magnetic block 47, a second magnetic block 48, a storage ruler 49, a fourth scale line 50, a long groove 51, and a storage cover 53. The sleeve 45 is rotatably sleeved on the third connecting shaft 39. The third storage cavity 46 is fixedly connected to the outer wall of the sleeve 45. One end of the storage ruler 49 is slidably disposed in the third storage cavity 46. The other end of the storage ruler 49 is fixedly connected to the storage cover 53. The second magnetic block 48 is disposed in the storage cover 53. The first magnetic block 47 is fixedly installed on one side of the interior of the third storage cavity 46. The first magnetic block 47 and the second magnetic block 48 have opposite magnetic properties. The storage ruler 49 has a long groove 51 and a fourth scale line 50.

[0034] The front of the teaching platform 5 has a drawer 4 that can be pulled out.

[0035] In practical use, the user can use the suction cup 40 to attach the second disc 38 to the blackboard 8. A circle can be drawn along the perimeter of the first disc 37. Pulling the storage cover 53 separates the first magnet 47 and the second magnet 48, allowing the storage ruler 49 to be pulled out from the third storage cavity 46. Straight lines can be drawn using the storage ruler 49 by drawing lines within the elongated slot 51. Then, by rotating the second magnet 48, lines can be drawn again within the elongated slot 51. Connecting the two lines allows for the creation of any desired angle. The rubber band 44 can then be used to connect the lines. Connected to the three side posts 41, the positional relationship of the inscribed triangles of the circles can be visualized. By using the rubber band 44 fitted onto the central axis 52 and the two side posts 41, triangles at any angle can also be derived. The angle drawing mechanism 3 is stored in the drawer 4. Pressing down the first pressing block 23 separates the first hook and loop fastener 26 and the first loop fastener 27. Moving the first pressing block 23 moves the first connecting shaft 24, which in turn moves the first slider 16. Moving the first drawing ruler 17 allows it to be removed from the first storage cavity 13 and moved laterally to any position on the blackboard 8. Then, releasing the first pressing block 23 causes the first hook and loop fastener 26 and the first loop fastener 27 to stick together, fixing the first drawing ruler 17. The user can then draw vertical lines. Moving the first drawing ruler 17 back into the first storage cavity 13 and pressing the second pressing block 29 separates the second hook and loop fastener 32 and the second loop fastener 33. Moving the second pressing block 29 allows the drawing ruler 17 to move. The second connecting shaft 30 moves, which drives the second slider 21 to move. The movement of the second slider 21 drives the second drawing ruler 22 to move, allowing the second drawing ruler 22 to be moved out of the second storage cavity 18 and moved longitudinally to any position on the blackboard 8. Then, the second pressing block 29 is released, and the second hook and loop fastener 32 and the second hook and loop fastener 33 are stuck together, fixing the second drawing ruler 22. The user can then draw vertical lines. This is the overall workflow of the invention. This step can be repeated for the next use.

[0036] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows: This teaching aid integrates multiple geometric functions such as drawing circles, lines, angles, and constructing triangles, reducing the inconvenience for teachers to carry and change various teaching aids and improving classroom teaching efficiency. A suction cup firmly attaches the second disc to the blackboard, preventing slippage during use and ensuring the stability and accuracy of the drawings, suitable for rapid classroom demonstrations. With the help of a storage ruler, long slots, and rotating magnetic blocks, it allows for convenient and intuitive drawing of lines at arbitrary angles and in multiple directions, meeting diverse line-drawing needs in geometry teaching. The combination of rubber bands on the side posts and central axis vividly demonstrates geometric relationships such as circles with inscribed triangles and triangles with arbitrary angles, enhancing students' spatial imagination and comprehension. The angle drawing mechanism can be stored in corresponding storage cavities and drawers, with a compact structure that prevents exposed or lost parts, facilitating storage and portability. The straight-line drawing mechanism allows for rapid locking and releasing of the first and second drawing rulers, ensuring stable positioning and effectively preventing deviation during drawing, thus improving drawing accuracy.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
