[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] like Figures 1-6 ;

[0025] A mathematical model with adjustable function includes a first ruler 1 and a second ruler 11. The dimensions of the first ruler 1 and the second ruler 11 are completely matched. When the first ruler 1 and the second ruler 11 are assembled, they form a right-angle ruler for teaching mathematical model rulers. The increased width of the first ruler 1 and the second ruler 11 facilitates the support and storage of the triangle ruler component 22 and the semicircular ruler component 23. The first ruler 1 and the second ruler 11 are connected by a hinge, allowing the first ruler 1 and the second ruler 11 to be flipped and folded, reducing the space occupied by the rulers and making the dimensions of the first ruler 1 and the second ruler 11 adjustable. The first ruler 1 and the second ruler 11 are provided with an adjustment component 2, which enables the teaching mathematical model ruler to be adjusted and stored.

[0026] The adjustment assembly 2 includes a first support plate 21, a second support plate 211, and a limiting plate 212. The first support plate 21 is fixedly installed inside the first ruler plate 1. The first support plate 21 and the limiting plate 212 are used to snap and support the triangular ruler assembly 22 and magnetically connect the triangular ruler assembly 22. The second support plate 211 is fixedly installed inside the second ruler plate 11. The second support plate 211 is used to snap and support the semicircular ruler assembly 23 and magnetically connect the semicircular ruler assembly 23. The limiting plate 212 is fixedly installed between the first support plate 21 and the first ruler plate 1.

[0027] Furthermore, the first support plate 21 and the limiting plate 212 contain a magnetically adsorbed set square assembly 22, and the second support plate 211 contains a magnetically adsorbed semicircular ruler assembly 23. The set square assembly 22 includes a first strong magnetic ruler rod 221, a second strong magnetic ruler rod 222, and a third strong magnetic ruler rod 223. The first strong magnetic ruler rod 221, the second strong magnetic ruler rod 222, and the third strong magnetic ruler rod 223 are spliced ​​and combined together to form a slender ruler. Since the set square assembly 22 consists entirely of strong magnets, the first strong magnetic ruler rod 221, the second strong magnetic ruler rod 222, and the third strong magnetic ruler rod 223... The connection between the third strong magnetic ruler rod 223 is sufficiently stable. One end of the first strong magnetic ruler rod 221 magnetically attracts the second strong magnetic ruler rod 222, and the other end of the first strong magnetic ruler rod 221 magnetically attracts the third strong magnetic ruler rod 223. The other ends of the second strong magnetic ruler rod 222 and the third strong magnetic ruler rod 223 are magnetically attracted to each other. Because the first strong magnetic ruler rod 221, the second strong magnetic ruler rod 222, and the third strong magnetic ruler rod 223 are connected by magnetic attraction, it is also easy to disassemble and reassemble them, so that the slender ruler can be reassembled into a straight ruler. Figure 6 As shown, this allows the triangle ruler assembly 22 to not only be adjustable but also to have diverse effects. The semicircular ruler assembly 23 includes a third ruler plate 231 and a fourth ruler plate 232, which are connected by a hinge. Both the third ruler plate 231 and the fourth ruler plate 232 are quarter circles. After the third ruler plate 231 and the fourth ruler plate 232 are connected by hinge rotation, they form a semicircle for use as a semicircular ruler for teaching mathematical models. The third ruler plate 231 and the fourth ruler plate 232 are also magnetically attracted. When the third ruler plate 231 and the fourth ruler plate 232 are flipped and unfolded, they are magnetically attracted, making the unfolded use of the third ruler plate 231 and the fourth ruler plate 232 stable. When the third ruler plate 231 and the fourth ruler plate 232 are flipped and folded, they are magnetically attracted, making the folded placement and use of the third ruler plate 231 and the fourth ruler plate 232 stable and less space-consuming.

[0028] Furthermore, a first magnet 24 is installed on the inner wall of one corner of the first ruler plate 1, and a second magnet 241 is installed on the inner wall of one corner of the second ruler plate 11. The second magnet 241 is used to magnetically connect with the first magnet 24. When the first ruler plate 1 and the second ruler plate 11 are flipped and folded together, the triangle ruler assembly 22 and the semicircular ruler assembly 23 are folded together inward for protection, support, and storage. The magnetic connection between the first magnet 24 and the second magnet 241 ensures a stable connection between the first ruler plate 1 and the second ruler plate 11 after folding, preventing them from easily loosening and opening. A first socket 25 is installed at the bottom of the first ruler plate 1 for inserting the pin 27. The second magnet 241 is installed inside the second ruler plate 11. The socket 26 and the stop 28 are used to support the sliding of the pin 27. The pin 27 is inserted between the first socket 25 and the second socket 26. The outer surface of the pin 27 is covered with a rubber layer to increase the friction of the pin 27 and make it less likely to loosen and detach from the first socket 25. When the first ruler 1 and the second ruler 11 are flipped and unfolded, the pin 27 in the second socket 26 is pushed to insert the pin 27 into the first socket 25, connecting the first socket 25 and the second socket 26, thereby positioning the unfolded first ruler 1 and the second ruler 11 for easy unfolding and use. The stop 28 is used to limit the pin 27 and prevent the pin 27 from sliding and detaching from the second socket 26.

[0029] The working principle of this utility model is as follows: The third ruler plate 231 and the fourth ruler plate 232 are embedded and connected by a hinge. Both the third ruler plate 231 and the fourth ruler plate 232 are quarter circles. After the third ruler plate 231 and the fourth ruler plate 232 are connected by hinge rotation, they are combined into a semicircle for use as a semicircular ruler for teaching mathematical models. The third ruler plate 231 and the fourth ruler plate 232 are also magnetically attracted to each other. The third ruler plate 231 and the fourth ruler plate 232 are magnetically attracted to each other after being flipped, unfolded and folded, which increases stability and does not occupy space. The semicircular ruler component 23 is snapped into the second support plate 211 and is magnetically attracted to each other. Since the first strong magnetic ruler rod 221, the second strong magnetic ruler rod 222 and the third strong magnetic ruler rod 223 are magnetically attracted to each other, it is also easy to disassemble and reassemble, so that the slender ruler can be reassembled into a straight ruler. This makes the triangular ruler component 22 not only adjustable, but also has a variety of effects. The triangular ruler component 22 is snapped into the first support plate 211. The support plate 21 and the limiting plate 212 are magnetically connected. When the first ruler plate 1 and the second ruler plate 11 are flipped and unfolded, the pin 27 in the second socket 26 is pushed, so that the pin 27 is inserted into the first socket 25, connecting the first socket 25 and the second socket 26, thereby positioning the unfolded first ruler plate 1 and the second ruler plate 11, making it easy for the first ruler plate 1 and the second ruler plate 11 to unfold and be used. The stop block 28 is used to limit the pin 27 to prevent the pin 27 from sliding off the second socket 26. When the first ruler plate 1 and the second ruler plate 11 are flipped and folded together, the triangle ruler assembly 22 and the semicircular ruler assembly 23 are brought together inward for protection, support and storage. The magnetic connection between the first magnet 24 and the second magnet 241 makes the connection of the first ruler plate 1 and the second ruler plate 11 stable after folding, preventing them from easily loosening and opening, thereby adjusting the first ruler plate 1 and the second ruler plate 11, reducing the space occupied and making them easy to carry.
