CN2834932Y - High-efficiency multifunctional triangle - Google Patents

Abstract

The utility model relates to a high efficiency multifunctional triangle. The utility model is characterized in that the surface of the triangle is drawn with a protractor and the bottom edge of the triangle is provided with small holes in sequence. When the utility model is used, people can normally use the triangle to measure or draw pictures and can also use the protractor to measure angle. When people draw circular patterns, people firstly measure the radius of circles, a pointer is inserted in a small circular hole, a pencil is inserted in another small hole, the distance between the two small holes is needed to be ensured to be equal to the radius of the circle to be draw, the triangle is rotated taking the pointer point as an origin point, the pattern left bt the pencil on paper is the pattern of the circle to be draw. The utility model has the advantages of reasonable structure, complete function, convenience, good practicability, simple technology, etc. The utility model can provide the functions of a protractor and a compasses under the premise of exerting the self functions of triangle, saves learning tools and enhances learning efficiency.

Description

The high-efficiency multi-function set square

Technical field the utility model relates to a kind of learning tool, especially a kind ofly can take measurement of an angle and can draw round high-efficiency multi-function set square.

The technical background set square is people's important instruments in studying and living.But the function of set square is comparatively single at present, and painting function can only be provided, when taking measurement of an angle and painting circular pattern, and necessary replacing instrument, and often the replacing instrument certainly will cause waste of time, and multiple instrument also takies great space.In order to raise the efficiency when working, we are sought after a kind of high-efficiency multi-function set square that integrates various tool.

The summary of the invention the purpose of this utility model provides a kind of high-efficiency multi-function set square, is used to solve common set square function simple question.

For achieving the above object, the utility model high-efficiency multi-function set square comprises transparent isoceles triangle plate, is painted with protractor on the surface of set square, and the centre point of protractor is a set square base mid point; From left to right be provided with aperture successively on the set square base, and the spacing of per two apertures is 1 millimeter.

After adopting said structure, the user can rule, paint the angle with set square, when drawing circular pattern, the user is fixed in the circular hole of set square base with a root pointer, on the base, measure radius of circle to be painted then, be inserted in another aperture, guarantee that the distance between two apertures equals to get final product for drawing radius of a circle with pencil, last fixed pointers, Propelling pencil with sharpener in cap end, the figure that the pencil end is drawn is a circle to be painted; Protractor act on common protractor unanimity, the function that takes measurement of an angle is provided.

The utility model has the advantages that: rational in infrastructure, multiple functional, convenient and practical, technology is simple, under the prerequisite of performance set square effect itself, also can be the function that the user provides protractor and compasses, the saving learning tool improves learning efficiency.

Description of drawings Fig. 1 is the overall structure schematic diagram of the utility model high-efficiency multi-function set square.

The specific embodiment as shown in Figure 1, the utility model high-efficiency multi-function set square comprises transparent isoceles triangle plate 1, is painted with protractor 2 on the surface of set square 1, the centre point of protractor 2 is set square 1 a base mid point; From left to right be provided with aperture 3 successively on set square 1 base; The spacing of per two apertures 3 is 1 millimeter.When using, the user can normally use set square 1 to measure or paint, and goes back 2 pairs of available quantity hornworks and measures various angles; When the user draws circular pattern, measure circular radius earlier, one root pointer is inserted in the small sircle hole 3, be inserted in another aperture 3 with pencil then, must guarantee that distance between two apertures 3 equals radius of a circle to be painted and gets final product, be initial point rotary triangle plate 1 with the pointer point at last, the figure that pencil stays on paper just is the figure of circle to be painted.

Claims (2)

1, a kind of high-efficiency multi-function set square comprises transparent isoceles triangle plate (1), it is characterized in that: be painted with protractor (2) on the surface of set square (1), the centre point of protractor (2) is set square (a 1) base mid point; From left to right be provided with aperture (3) successively on set square (1) base.

2, as claim 1 described high-efficiency multi-function set square, it is characterized in that: the spacing of per two apertures (3) is 1 millimeter.
