In this way, the two sides of the first through hole and the second through hole are set to the maximum extent, so that the drawn figure is larger and convenient to use.
- the third acute angle of the first through hole and the fourth acute angle of the second through hole are all arranged in an arc structure. This arrangement increases the joint area of the third acute angle and the fourth acute angle, thereby increasing the robustness of the teaching rule.
- the straight side is marked with a scale.
- This teaching ruler can be used as a ruler.
- the teaching ruler further comprises a shape-shaped through hole and a fixing hole disposed at one end of the strip-shaped through hole; the teaching ruler further comprises a fixing body fixed on the side wall of the strip-shaped through hole A fixed slider for placing a placement hole of a chalk, the fixed slider being slidable on a sidewall of the strip through hole.
- the teaching ruler can be adjusted to adjust the fixed slider to draw different sizes.
- the strip-shaped through holes are provided with opposite serrations on both sides.
- the two sides of the strip through hole are provided with opposite serrations for fixing the slider, which is convenient for use.
- the fixing hole is a circular hole.
- the fixing member in which the circular structure is inserted into the fixing hole is better fixed, and can be fixed by using chalk.
- the teaching ruler is transparently disposed.
- the transparent settings show the parts that need to be added for easy drawing.
- the utility model can draw and measure the angle because the teaching ruler is a protractor; the first side and the second side of the through hole of the teaching ruler intersect at a 90-degree scale to form a first right angle, and the first side and the straight edge of the teaching ruler are clipped.
- the angle is 45 degrees, the first side, the second side and the straight side are drawn in chalk, and then the equalizer triangle is used to form a isosceles right triangle; the third and fourth sides of the through hole intersect at 60 degrees.
- a second right angle is formed at a 120-degree scale, and the angle between the third side and the straight side is 60 degrees, and the third side, the fourth side, and the straight side are drawn by chalk, and then the teaching ruler is used to complete the formation.
- the 30-degree, 60-degree right-angled triangle thus the teaching ruler can also be used as a triangular plate, which is convenient to carry when the teacher teaches; and also does not need to frequently change different teaching rulers when used, and is convenient to use. And this teaching rule can also be used to produce miniature students or teachers.
- FIG. 1 is a schematic structural view of a teaching ruler according to an embodiment of the present invention.
- FIG. 2 is another schematic structural view of a teaching ruler according to an embodiment of the present invention.
- the utility model discloses a teaching ruler, which is generally a protractor. As shown in FIG. 1 and FIG. 2, a through hole is formed, wherein the first side 1 and the second side 2 intersect at a 90 degree graduation to form a first right angle, and the first The angle between the edge 1 and the straight edge 6 of the teaching ruler is 45 degrees; the third side 3 and the fourth side 4 of the through hole intersect at a 60 degree or 120 degree mark to form a second right angle, and the third side 3 is at an angle of 60 degrees to the straight edge 6.
- the utility model can draw and measure the angle because the teaching ruler is a protractor; the first side 1 and the second side 2 of the through hole of the teaching ruler intersect at a 90 degree mark to form a first right angle, and the first side 1 and the teaching ruler line
- the angle of the edge 6 is 45 degrees, and the first side 1, the second side 2 and the straight side 6 are drawn in chalk, and then the heel triangle is formed by the addition of the teaching ruler; the third side of the through hole 3 And the fourth side 4 intersects at a 60 degree or 120 degree scale to form a second right angle, and the angle between the third side 3 and the straight side 6 is 60 degrees, and the third side 3, the fourth side 4, and the straight line are drawn by chalk.
- the circumference of one side surface of the arc side 5 of the teaching ruler is marked with a scale, thereby facilitating the drawing of the circle and the measurement of the angle.
- the extension lines of the second side 2 and the fourth side 4 intersect at the intersection point 8, so that the painting is set
- the straight edge 6 is marked with a scale, so that the teaching ruler can be used as a ruler, which is convenient to use, and does not need to carry a ruler.
- the scale on the side of the line and the scale on the side of the arc are on the same side.
- the intersection of the second side 2 and the fourth side 4, that is, the intersection point 8 is integrally provided with the teaching ruler, so that the through hole forms the first through hole 10 and the second pass of the triangular structure.
- the hole 11 thus increases the strength of the teaching ruler.
- the first acute angle of the first through hole 10 and the second acute angle of the second through hole 11 are respectively located at both ends of the straight side 6 of the teaching ruler, so that two of the right angles of the two right angles can be set to the maximum, that is, the first side
- the maximum setting of 1 and 3 sides 3 makes the drawn graphics larger and easier to use.
- the third acute angle of the first through hole 10 and the fourth acute angle of the second through hole 11 are both arranged in an arc shape, that is, the two opposite acute angles of the first through hole 10 and the second through hole 11 at the intersection 8 are set.
- the curved structure increases the area of the joint between the two, thereby increasing the firmness of the teaching ruler, and is arranged in an arc-shaped structure without corners for easy handling; of course, the first right angle, the second right angle, the first acute angle and The second acute angle can also be set to an arc structure, which also increases the strength of the teaching ruler and facilitates handling.
- the teaching ruler further has a strip-shaped through hole 12 having a width slightly larger than a chalk and a fixing hole 9 disposed at the end of the strip-shaped through hole 12; the teaching ruler further includes a fixing A fixing slider 7 for fixing the placement hole of the chalk is disposed on the side wall of the strip through hole 12, and the fixing slider 7 can slide on the side wall of the strip through hole 12, and the fixing slider 7 is replaced in the strip shape as needed.
- the position on the side wall of the through hole 12 is such that a certain object (like a readily available pen, chalk, etc.) is inserted into the fixing hole 9 as a center, and the chalk is inserted into the position of the fixing hole of the fixed slider 7, so that a circle can be realized. Drawing.
- the fixing hole 9 has a circular structure, which facilitates the insertion and cooperation of chalk, pen and the like, as well as the convenience of drawing a circle and reducing the resistance.
- the fixing hole 9 is located at the right end of the strip-shaped through hole 12, that is, the user faces the right end of the scale on the side of the teaching ruler, so that the setting is convenient for drawing a circle; of course, it is also feasible to set it at the left end.
- the two sides of the strip through hole 12 are provided with opposite serrations for limiting and fixing the fixed slider 7.
- the serrations on both sides of the strip through hole 12 are completely symmetrically arranged, and the serration is Comb serrated.
- the material of the teaching ruler of the utility model can be transparently arranged by using a plastic material, so that it is convenient to see the parts that need to be supplemented when drawing, and it is convenient for drawing, which is advantageous for use. Of course, other transparent materials can also be used.
- the utility model can also be produced into a small structure for use by students or teachers. You don't have to carry too many teaching feet. You only need this one ruler, which is convenient to use and carry.
