Description

Technical Field

[0001] This utility model relates to the field of plotter technology, and more specifically, to a mathematical plotter. Background Technology

[0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. It plays an irreplaceable role in human history and social life, and is also an essential tool for learning and researching modern science and technology. In mathematics, abstract concepts are often visualized through drawing. For example, drawing function graphs and geometric figures transforms algebraic problems into visual information, allowing for a more intuitive understanding of abstract concepts such as variable relationships and geometric properties. Drawing can also train spatial thinking; for instance, constructing solid figures by combining points, lines, and planes can develop three-dimensional spatial imagination. Mathematical drawing requires tools such as rulers, protractors, and compasses. However, drawing angle lines of specific lengths or arcs requires first determining the angle with a protractor before drawing the straight line with a ruler or the arc with a compass, which is inconvenient. Therefore, we propose a mathematical drawing tool. Utility Model Content

[0030] Example 3:

[0031] Based on Embodiment 1 and Embodiment 2, such as Figure 1 , Figure 2 and Figure 4As shown, the square marking mechanism 3 includes a square groove 30, a first straight scale 31, and a second straight scale 32 disposed on a ruler plate 1. The first straight scale 31 and the second straight scale 32 are respectively located on the outer sides of the inner cavity of the square groove 30. The zero point of the first straight scale 31 and the second straight scale 32 are aligned with one corner of the inner cavity of the square groove 30. A horizontal plate 33 is slidably connected to the inner cavity of the square groove 30, and a vertical plate 35 is slidably connected to the inner cavity of the square groove 30. A through groove 34 is provided inside the horizontal plate 33, and the vertical plate 35 is movably sleeved to the through groove 35. The thickness of the inner cavity of the slot 34 is equal to the thickness of the vertical plate 35, ensuring the stability of the vertical plate 35 sliding within the inner cavity of the slot 34. In addition, except for the stud 23, the compression cap 24, the marking limit tube 21 and the internal thread tube 22, which are all made of transparent material, the first indicator arrow 8, the first angle ruler 9, the first corner length ruler 10, the second corner length ruler 11, the main length ruler 12, the second angle ruler 14, the first straight scale ruler 31, the second straight scale ruler 32, the radius length ruler 26 and the second indicator arrow 27 are all printed.

[0032] It should be noted that this utility model is a mathematical drawing plotter. When it is necessary to draw a figure at a specific angle, the rotating frame 7 is rotated to adjust the angle between the fixed frame 5 and the rotating frame 7. At the same time, the angle between the fixed frame 5 and the rotating frame 7 is controlled by the cooperation between the first indicator arrow 8 and the first angle ruler 9. In addition, the position where the inner sides of the fixed frame 5 and the rotating frame 7 coincide is the sharp corner position of the angle line, so that the drawing pen can rest against the inner side of the fixed frame 5 and the rotating frame 7 to draw the line. The length of the two side lines is determined and controlled by the first side length ruler 10 and the second side length ruler 11, so as to realize the drawing of a figure with a specific angle and two side lengths at one time. In addition, the sharp corner position is not aligned with the zero point position of the first side length ruler 10 and the second side length ruler 11. The drawing end point corresponding to the first side length ruler 10 and the second side length ruler 11 can be calculated, that is, the value of the drawing end point minus the value of the sharp corner position to obtain the specific drawing line length value.

[0033] When it is necessary to draw a circle or arc with a specific radius, firstly, the sliding adjustment seat 19 moves in the inner cavity of the movable groove 16. The radius of the circle or arc is determined by the cooperation of the pointed corner 20 and the radius length ruler 26. Then, the lever block 25 is rotated to drive the extrusion cover 24 and the stud 23 to rotate. The threaded cooperation between the stud 23 and the internal thread tube 22 drives the extrusion cover 24 to move down. The extrusion cover 24 is used to press the top of the turntable 15 to fix the position of the adjustment seat 19 at this time. Then, the pen tip of the drawing pen is inserted into the drawing limit tube 21. At this time, the turntable 15 is rotated to drive the pen tip to rotate synchronously. When the turntable 15 rotates one revolution, the pen tip draws a complete circle on the paper. When the turntable 15 is rotated at a certain angle, the pen tip draws an arc with a specific angle on the paper. At the same time, the angle of the arc can be controlled by the second indicator arrow 27 and the second angle ruler 14.

[0034] When drawing a square shape, slide the horizontal plate 33 and vertical plate 35 inside the square groove 30. Control the length of the two adjacent sides of the square shape by using the first straight scale 31 and the side of the vertical plate 35, and the second straight scale 32 and the side of the horizontal plate 33. This allows the pen to draw a square pattern close to the two inner walls of the square groove 30 and the inner sides of the horizontal plate 33 and vertical plate 35. Square shapes of different sizes can be drawn as needed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
