Abstract
The utility model discloses a ruler, which comprises a transparent ruler body, wherein a scale is arranged on the straight flange of the ruler body, cutting lines are also arranged on the ruler body, angles between the rutting lines and the straight flange of the ruler are respectively 30 degrees, 45 degrees, 60 degrees or 90 degrees, or random combination of the four angels. Four cutting lines are arranged on the ruler body, and the angles between the four cutting lines and the straight flange are respectively 30 degrees, 45 degrees, 60 degrees and 90 degrees. According to the ruler, when a line with angle of 30 degrees with the known segment is needed to be drawn, the 30-degree cutting line is used to be coincident with the known segment, thus the straight flange of the ruler forms angle of 30 degrees with the known segment, the line with the angle of 30 degrees with the known segment can be drawn along the straight flange, thus the convenience is brought for use, a triangular rule or protractor is not needed to be used, and answer speed is favorably increased. Other angles such as 45 degrees, 60 degrees or 90 degrees can be obtained according on the method.
Description
Technical field
The utility model relates to a kind of stationery, especially a kind of ruler.
Background technology
Ruler uses very extensively in learning life.Existing ruler can only be drawn horizontal line, can not be decorated with the line of angle.Be decorated with the line of angle and must use protractor or set square, must look for chi when therefore using, change chi, comparatively inconvenience during use.
People hope always and can draw some angles commonly used with ruler, like 30 degree, 45 degree, 60 degree or 90 degree.
Summary of the invention
The purpose of the utility model is a kind of ruler of some angles commonly used that can draw easily that designs for the deficiency that solves above-mentioned technology.
The ruler that the utility model designed; Comprise transparent ruler body, straight flange is provided with scale on the ruler body, also is provided with line of weakness on the said ruler body; Said line of weakness and ruler straight flange are 30 degree, 45 degree, 60 degree or 90 degree, the combination in any of perhaps aforementioned four kinds of angles.
As preferably:
Said ruler body is provided with four line of weakness, and four line of weakness are 30 degree, 45 degree, 60 degree and 90 degree with the ruler straight flange respectively;
Three line of weakness that described and ruler straight flange is 30 degree, 60 degree, 90 degree have same summit, and 45 degree can be positioned at other position.
Described line of weakness extends to the straight flange of ruler body.
The ruler that the utility model designed when needing one in picture and known line segment to be the lines of 30 degree, makes 30 degree line of weakness overlap with this known line segment; Like this; The straight flange of ruler is inevitable to be 30 degree with this known line segment, and can draw along straight flange is the lines of 30 degree with this known line segment, very easy to use like this; Need not to use set square or protractor, help improving answer speed.Other angles as: 45 degree, 60 degree or 90 degree also can be drawn according to the method described above.
Description of drawings
Fig. 1 is embodiment 1 structural representation;
Fig. 2 is embodiment 2 structural representations;
Fig. 3 is embodiment 3 structural representations;
Among the figure: ruler body 1; Ruler straight flange 2; Line of weakness 3; Be 30 degree line of weakness 30 with the ruler straight flange;
Be 45 degree line of weakness 45 with the ruler straight flange;
Be 60 degree line of weakness 60 with the ruler straight flange;
Be 90 degree line of weakness 90 with the ruler straight flange.
The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Embodiment 1:
As shown in Figure 1, the described ruler of present embodiment comprises transparent ruler body 1, and straight flange is provided with scale on the ruler body 1, also is provided with line of weakness 3 on the said ruler body 1, and said line of weakness 3 is 30 degree with ruler straight flange 2.
When needing one in picture and known line segment to be the lines of 30 degree; 30 degree line of weakness 3 are overlapped with this known line segment, and like this, the straight flange of ruler is inevitable to be 30 degree with this known line segment; Can draw and this known line segment is 30 lines of spending along straight flange; Very easy to use like this, need not to use set square or protractor, help improving answer speed.
Certainly, said line of weakness 3 can also be 45 degree, 60 degree and 90 degree with ruler straight flange 2.
Embodiment 2:
As shown in Figure 2, the described ruler of present embodiment comprises transparent ruler body 1, and straight flange is provided with scale on the ruler body 1, and said ruler body 1 is provided with 3, four line of weakness 3 of four line of weakness and is 30 degree, 45 degree, 60 degree and 90 degree with ruler straight flange 2 respectively; Three line of weakness 3 that described and ruler straight flange 2 is 30 degree, 60 degree, 90 degree have same summit, and 45 degree can be positioned at other position.This several angles have been arranged, through putting the position of ruler, other angles such as 120 degree, 135 degree, 150 degree of can easily drawing.
As shown in Figure 3, the described ruler of present embodiment, different with embodiment 2 is the straight flange that described line of weakness 3 extends to ruler body 1.
The marrow of the utility model is the line of weakness 3 of on ruler body 1, establishing fixed angle; During mapping; Line of weakness 3 overlaps with known line segment; Be known fixed angle and the straight flange of ruler is inevitable with this known line segment, can draw along straight flange is the lines of fixed angle with this known line segment, thereby realizes the function that ruler can be drawn angle line.As long as profit is wanted above-mentioned marrow,,, all should be regarded as the replacement that is equal to of angle described in this patent like 15 degree, 25 degree, 80 degree or the like even angle is other values.
Claims (4)
1. ruler; Comprise transparent ruler body, straight flange is provided with scale on the ruler body, it is characterized in that also being provided with line of weakness on the said ruler body; Said line of weakness and ruler straight flange are 30 degree, 45 degree, 60 degree or 90 degree, the combination in any of perhaps aforementioned four kinds of angles.
