[0002] Mathematics is a fundamental science that studies concepts such as quantity, structure, space, and information. Its language is highly precise, and its definitions, theorems, and propositions are all derived through rigorous proof and derivation. This precision enables mathematics to serve as the foundation and tool for other scientific fields. The mathematics teaching ruler is a tool specifically designed for mathematics teaching. It combines the functions of a protractor, ruler, and set square, making it convenient for teachers to draw and measure various geometric figures in the mathematics classroom.

[0003] A search revealed that Chinese Patent CN218315991U discloses a multifunctional mathematical teaching ruler. This ruler addresses the issue that existing technology can only draw arcs with a fixed radius, and is unusable when smaller or larger arcs are needed. Therefore, improvements are required to meet practical needs, thus solving the problem that existing technology can only draw arcs with a fixed radius and is unusable when smaller or larger arcs are required.

[0004] The aforementioned multi-functional mathematical ruler is convenient for drawing arcs. However, when used as a teaching tool on a blackboard, the teacher draws on the blackboard with chalk on the ruler. After drawing, the measuring side of the ruler will accumulate a lot of dust due to the chalk dust. If the dust on this side of the ruler is not cleaned in time, the scale on this side of the ruler will be eroded by the dust over a long period of time, making the scale values ​​difficult to read and shortening the lifespan of the ruler.

[0035] The cleaning component includes a fixing rod 2, which is fixedly connected to the upper surface of the ruler body 1. Two square grooves 3 are formed on the upper surface of the fixing rod 2. A sliding sleeve 4 is slidably connected to the outside of the fixing rod 2. A connecting sleeve 5 is fixedly connected to one side of the sliding sleeve 4. A threaded sleeve 6 is fixedly connected to the upper surface of the connecting sleeve 5. A first bolt 7 is threadedly connected inside the threaded sleeve 6. A connecting block 8 is slidably connected inside the connecting sleeve 5. An installation block 9 is fixedly connected to the lower surface of the connecting block 8. A sponge 10 is provided on the inner wall of the installation block 9. The square grooves 3 facilitate the engagement of the T-shaped block 13. The threaded sleeve 6 is used for the installation of the first bolt 7. The installation block 9 facilitates the installation of the sponge 10.

[0036] As attached Figure 5 As shown, the sliding sleeve 4 has a first mounting groove 11 inside. A pull rod 12 is slidably connected to the upper surface of the first mounting groove 11. A T-block 13 is fixedly connected to one end of the pull rod 12. A spring 14 is fixedly connected to the upper surface of the T-block 13. One end of the spring 14 is fixedly connected to the inside of the first mounting groove 11. The first mounting groove 11 facilitates the movement of the T-block 13, and the spring 14 is used to push the T-block 13.

[0037] As attached Figure 1 As shown, a circle drawing component is provided in the middle of the ruler body 1. The circle drawing component includes a slide groove 28, which is opened in the middle of the ruler body 1. A sliding box 15 is slidably connected inside the slide groove 28. The sliding box 15 can be adjusted in position inside the slide groove 28 to adjust the radius of the circle as needed.

[0038] As attached Figure 8As shown, the sliding box 15 has a second mounting groove 16 inside, and a double-ended stud 18 is rotatably connected inside the second mounting groove 16. A first bevel gear 19 is fixedly connected to the middle of the double-ended stud 18. A second bevel gear 20 is rotatably connected to the upper surface of the second mounting groove 16. The first bevel gear 19 and the second bevel gear 20 are meshed. A connecting groove 17 is opened on the lower surface of the second mounting groove 16. A knob 21 is fixedly connected to the second bevel gear 20 through a shaft. Two moving blocks 22 are threadedly connected to the outside of the double-ended stud 18. A clamping plate 23 is fixedly connected to the lower surface of the moving blocks 22. The upper surfaces of the two moving blocks 22 are slidably connected inside the connecting groove 17. A threaded hole 24 is opened on one side of the sliding box 15. A second bolt 25 is threaded inside the threaded hole 24. The two sides of the double-ended stud 18 have threads in opposite directions. The clamping plate 23 improves the stability of chalk installation. The threaded hole 24 is used to install the second bolt 25.

[0039] As attached Figure 1 As shown, one end of the ruler body 1 is rotatably connected to a rotating shaft 26, which facilitates the rotation of the ruler body 1 when the magnet 27 is fixedly attracted.

[0040] As attached Figure 6 As shown, a magnet 27 is fixedly connected to one end of the rotating shaft 26 for adsorption onto the blackboard.

[0041] Working principle: When cleaning one side of the ruler body 1, pull up the lever 12. The lever 12 pulls the T-block 13 away from the corresponding square groove 3, causing the sliding sleeve 4 to be released from its limit. Then, slide the sliding sleeve 4 outside the fixed rod 2. When the sliding sleeve 4 slides, it indirectly drives the mounting block 9 and the sponge 10 to move on one side of the ruler body 1, thereby wiping away the dust on one side of the ruler body 1. When the mounting block 9 moves from one end of the ruler body 1 to the other end, release the lever 12. Under the action of the spring 14 pushing the T-block 13, the T-block 13 is inserted into the corresponding square groove 3, so that the mounting block 9 is fixed. When disassembling the sponge 10 and the mounting block 9, tighten the first bolt 7 to release the first bolt 7 from the tight contact with the connecting block 8. Then, hold the mounting block 9 and pull the connecting block 8 out of the interior of the connecting sleeve 5, thereby disassembling the mounting block 9 and the sponge 10 for replacement.

[0042] When it is necessary to draw a circle using the ruler body 1, first place the chalk into the sliding box 15, then turn the knob 21, which drives the second bevel gear 20 to rotate via the shaft. Through the meshing of the second bevel gear 20 with the first bevel gear 19, the first bevel gear 19 is driven to rotate, thereby driving the double-direction stud 18 to rotate. The opposite direction threads on both sides of the double-direction stud 18 facilitate the movement of the moving blocks 22 on both sides of the double-direction stud 18 as they slide inside the connecting groove 17, bringing them closer together, so that the clamping plates 23 on both sides... The chalk is brought close together to clamp and fix it in place. Then, the second bolt 25 is loosened to make the sliding box 15 movable. The sliding box 15 is then slid to slide inside the slide groove 28, which makes it easy to adjust the radius of the circle to be drawn. After moving to the appropriate position, the second bolt 25 is tightened under the action of the threaded hole 24 to fix the sliding box 15. Then, the ruler body 1 is positioned on the blackboard by using the magnet 27 to attract the magnet 27. The ruler body 1 is rotated to draw a circle.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
