Abstract

The utility model relates to a multi-functional ruler which comprises a circular transparent sheet; Angle of 0 degree to 360 degrees are subsequently marked on the edge of the circular transparent sheet; length scales are marked towards both sides and jacks spaced with the same distance are arranged on the axis surface of the transparent sheet with connecting lines between scales from 0 degree to 180 degrees as axes and the circle center as the point of origin; and right-angled triangles are carved on both sides of the axis, and openings are opened along the short sides of the triangles. During angle measurement, the user superposes the circle center and the top point of the angle to be measured, and measures with the angle scales on the surface of the transparent sheet; during circle drawing, the user can directly draw along the edge of the transparent sheet, insert a pointer into a jack on the axis and pencil head into other jacks, to fix the pointer and rotate the pencil head at the same time, so as to use the pencil head to draw circular patterns; during angle drawing, the user can draw with the effect of an angle gauge, or draw directly along the opening on the edge of a triangular plate. The multi-functional ruler has the advantages of comprehensive functions, reasonable structure, convenient operation, novel model and the like.

Description

Multifunctional ruler

Technical field the utility model relates to a kind of drawing instrument, especially a kind of multifunctional ruler.

Background technology is in study and work, and the kind of ruler is a lot, as: ruler, set square, "T"-shaped chi or the like.But all there is the problem of function singleness in which kind of ruler.In addition, present ruler can only be measured length, angle or draw straight line, triangle, then must use compasses instead and could realize when drawing circular pattern, and also therefore people must carry stationery such as compasses, ruler simultaneously, it is excessive to take up room, and makes troubles to people.For this reason, we provide a kind of multifunctional ruler to solve very necessity of the problems referred to above.

The summary of the invention the purpose of this utility model provides a kind of multifunctional ruler, is used to solve problems such as the standard rule subfunction is single, inconvenience use.

For achieving the above object, the utility model multifunctional ruler comprises circular transparent plate, the angle value of from 0 to 360 ° of marking in turn at the circular transparent plate edge; On the circular transparent plate with the line between 0 to 180 ° of marking point as axis, on the axis surface be that initial point is to both sides marking length scale and equidistantly offer jack with the center of circle; Scribe right angled triangle respectively in the axis both sides, and all be long limit with the axis, the angle of two right angled triangles is respectively 30 °, 60 °, 90 ° and 45 °, 45 °, 90 °, and offers opening along the minor face of right angled triangle.

After adopting said structure, when taking measurement of an angle, the user overlaps with angular vertex to be measured with round dot, utilizes the angle index on transparent panel surface to measure, the effect of performance protractor; Draw bowlder, just can directly draw along the circular transparent plate edge, also available pointer assigns into a jack on the axis, inserts other jacks with nib in addition, and fixed pointers is rotated nib simultaneously, utilizes nib to draw circular pattern; When drawing angle, but the drafting of use amount hornwork effect also can directly be drawn along the set square rim openings; In addition, the user also can utilize axis to carry out linear measure longimetry and drafting.

Compared with the prior art, the beneficial effects of the utility model are: complete function, rational in infrastructure, easy and simple to handle, modern design, integrate protractor, compasses, set square function, and can directly draw out 30 °, 45 °, 60 °, 90 ° angle, improve study and work efficient.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model multifunctional ruler.

Number in the figure: 1 is that transparent panel, 2 is that length scale, 3 is that jack, 4 is that right angled triangle, 5 is opening.

The specific embodiment as shown in Figure 1, the utility model multifunctional ruler comprises circular transparent plate 1, the angle value of from 0 to 360 ° of marking in turn at circular transparent plate 1 edge; On the circular transparent plate 1 with the line between 0 to 180 ° of marking point as axis, on the axis surface be that initial point is to both sides marking length scale 2 and equidistantly offer jack 3 with the center of circle; Scribe right angled triangle 4 respectively in the axis both sides, and all be long limit with the axis, the angle of two right angled triangles is respectively 30 °, 60 °, 90 ° and 45 °, 45 °, 90 °, and offers opening 5 along the minor face of right angled triangle 4.

Claims

1, a kind of multifunctional ruler comprises circular transparent plate (1), it is characterized in that: the angle value of from 0 to 360 ° of marking in turn at circular transparent plate (1) edge; Going up with the line between 0 to 180 ° of marking point as axis in circular transparent plate (1), is that initial point is also equidistantly offered jack (3) to both sides marking length scale (2) on the axis surface with the center of circle; Scribe right angled triangle (4) in the axis both sides respectively, and all be long limit with the axis, the angle of two right angled triangles is respectively 30 °, 60 °, 90 ° and 45 °, 45 °, 90 °, and offers opening (5) along the minor face of right angled triangle (4).
