Description

Multifunctional ruler

Technical Field

The utility model relates to a measuring tool, especially a multifunctional ruler.

Background

The ruler, the set square and the protractor are necessary stationery for students and teachers in middle and primary schools.

The existing set square is generally provided with a graduated scale and is generally divided into a 45-degree angle set square and a 30-degree angle set square. However, such a set square has a single function and mainly only functions as a ruler. The angles of 45 degrees and 30 degrees are rarely used in learning and teaching, namely the angles of 45 degrees, 30 degrees and 60 degrees are drawn by using the triangular plate, because scales are not marked from the top points of the corresponding angles, generally, two straight lines forming the angles of 45 degrees, 30 degrees or 60 degrees can be drawn firstly, then the two straight lines are delayed until the top points of the angles are intersected, and then the two rays are drawn to the corresponding lengths respectively. The use process is tedious and time-consuming, and the angle that is got is also limited aforementioned three angles, and is comparatively single.

There are also a number of designs which combine protractors and triangular plates. These designs tend to separate the 0 and 180 lines of the protractor from the scale of the triangle. When the protractor and the triangular plate are combined, after a straight line is drawn, when a straight line which forms a specified angle with the straight line and has a specified length is continuously drawn from a certain point on the straight line, the point is required to be taken, the circle center of the protractor is coincided with the point, a certain angle line of the protractor is coincided with the straight line, a second point of the corresponding angle is taken on the excircle of the protractor, the circle center and the second point are connected by using the edge of the straight ruler, and a line with the corresponding length is drawn. This drawing is virtually indistinguishable from drawing using a protractor and a ruler, respectively.

The ruler is characterized in that the other ruler is made of transparent plastic into a wider rectangle, ruler scales are arranged on the side of the rectangle, figures such as squares, rectangles, triangles, pentagons and circles are hollowed out on the ruler, and a protractor is integrated inside or outside the rectangle. Because the polygon is hollowed out on the ruler, the polygon is smaller and is not beneficial to drawing actually, or the whole ruler is larger, so that the ruler is very inconvenient to carry, especially under the condition that the stationery box of a student is smaller.

In conclusion, when the existing set square, protractor or multifunctional ruler is used, the steps are complicated, or the polygonal figure is small, or the multifunctional ruler is large in size, inconvenient to carry and use, and high in production cost. These combinations are simply straight edges, protractors and/or polygons, and do not provide substantial convenience in drawing.
