Abstract

The utility model relates to a multi-purpose ruler. A main body of the multi-purpose ruler is a strip-shaped transparent substrate, scales are designed on two side edges along the length direction of the substrate, and correspond vertically up and down, a left angle measuring line is designed on the left end of the substrate, the left angle measuring line and the edge of the substrate form a 30-degree angle, a right angle measuring line is designed on the right end of the substrate, and the right angle measuring line and the edge of the substrate form a 45-degree angle. As the scale marks are symmetrically arranged on two sides of the ruler, thus being beneficial to drawing parallel line and the vertical line; and as 30-degree angle, 60-degree angle and 45-degree angle are designed on two ends of the ruler, the multi-purpose ruler can replace the triangular ruler and be multi-purpose.

Description

Multipurpose ruler
Technical field
The utility model relates to a kind of student's study article, particularly a kind of Multipurpose ruler.
Background technology
Now in student's mathematics, the geometrical learning process; usually can do some parallel lines, vertical line and 30 degree, 60 degree, miter angle; in the existing instrument; ruler can only be drawn straight line; there is not other function; though protractor can draw the angle accurately but its volume is bigger, and it can not draw straight line, uses also inconvenient.
The utility model content
The purpose of this utility model provides a kind of ruler that the picture straight line can be done equality line and angle commonly used again easily that gets final product.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of Multipurpose ruler, its main body is the transparent matrix of a bar shaped, the matrix border design has scale, it is characterized in that: prolong on the dual-side of matrix length direction and all designed scale, two row scales are vertical up and down corresponding, left end design at matrix has left angulation line, the starting point of left side angulation line overlaps with the zero degree scale of matrix lower edge, and left angulation line becomes 30 degree angles with matrix border, right-hand member design at matrix has right angulation line, the terminal point of right angulation line overlaps with mantissa's scale of matrix upper limb, and right angulation line becomes miter angle with matrix border.
Characteristics of the present utility model be on the both sides of ruler all the design of symmetry graduation mark, be very beneficial for doing parallel lines and vertical line; Designed 30 °, 60 ° and 45 at two of ruler, can replace set square, the many usefulness of a chi can either be saved the pencil box space, can save again that set square is easily lost, the worry of rapid wear.
Be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the novel structural representation of this reality.
The specific embodiment
As shown in Figure 1, a kind of Multipurpose ruler, its main body is the transparent matrix of a bar shaped 1, matrix 1 edge designs has scale 2, prolong on the dual-side of matrix length direction and all designed scale, two row scales are vertical up and down corresponding, left end design at matrix 1 has left angulation line 3, the starting point of left side angulation line 3 overlaps with the zero degree scale of matrix lower edge, and left angulation line becomes 30 degree angles with matrix border, right-hand member design at matrix 1 has right angulation line 4, and the terminal point of right angulation line 4 overlaps with mantissa's scale of matrix upper limb, and right angulation line 4 becomes miter angle with matrix border.
