Description
Technical field
The utility model belongs to cultural goods, specifically a kind of novel ruler that has the protractor set square with multiple functions such as drawing straight line, measuring angle, picture triangle.
Background technology
In the study article that uses, ruler, protractor, isoceles triangle plate, hypotenuse set square have different separately functions respectively, are different schooling apparatus now, also are simultaneously the schooling apparatus that often uses.Owing to be the apparatus of multiple dispersion, forget sometimes and take wherein a kind of of generation that also lose wherein a kind of sometimes, this has brought inconvenience for our study.So invent and a kind of above-mentioned schooling apparatus commonly used is combined, the novel ruler that has the protractor set square with multiple functions such as drawing a straight line, measuring angle, picture triangle is necessary.
Summary of the invention
The purpose of this utility model provides a kind of novel ruler that has the protractor set square with multiple functions such as drawing straight line, measuring angle, picture triangle.
The purpose of this utility model is achieved in that
The novel ruler that has the protractor set square by ruler, protractor, set square, form, at an end of ruler, is provided with rivet ruler, protractor, isoceles triangle plate, hypotenuse set square is linked together.
At an end of ruler, protractor, be provided with rivet hole near the right angle of isoceles triangle plate, hypotenuse set square.
Main points of the present utility model are: utilize rivet that ruler, protractor, isoceles triangle plate, hypotenuse set square are combined.The position of rivet hole is near the right angle of an end of ruler, protractor and isoceles triangle plate, hypotenuse set square.Shrink when overlapping when above-mentioned each apparatus like this, the area minimum is convenient to take generation; When launching, each apparatus can non-interferingly work alone.
Ruler of the present utility model, protractor, isoceles triangle plate, each apparatus of hypotenuse set square can be made with identical materials, as all made of plastic.Also available different materials is made, and makes with timber as ruler, and protractor, isoceles triangle plate, hypotenuse set square are made of plastic.The rivet that the utility model uses can be used aluminium rivet, also can use screw that above-mentioned each apparatus is connected; The use screw connects, and then has demolition, installation advantage easily.
The utility model advantage is as follows:
1. have multiple functions such as the straight line of drawing, measuring angle, picture triangle.
2. be convenient to take generation, be convenient to keeping, be difficult for losing.
Description of drawings
Fig. 1 has the novel ruler expanded view of protractor set square for the utility model;
Fig. 2 has the folding figure of novel ruler of protractor set square for the utility model.
The specific embodiment
The utility model is described further by the specific embodiment below in conjunction with accompanying drawing.
The novel ruler that has the protractor set square, the ruler that is made of plastics (1), protractor (2), isoceles triangle plate (3), hypotenuse set square (4) are formed.Long 20 centimetres, wide 2 centimetres of ruler (1); Long 10 centimetres of protractor (2) diameter; Three angles of isoceles triangle plate (3) are respectively 90 °, 45 °, 45 °, 8 centimetres of the right angle length of sides; (4) three angles of hypotenuse set square are respectively 90 °, 60 °, 30 °, 6 centimetres of short right-angle sides.At an end of ruler (1), protractor (2), near the right angle of isoceles triangle plate (3), hypotenuse set square (4), be provided with rivet (5) ruler (1), protractor (2), isoceles triangle plate (3), hypotenuse set square (4) are linked together.Rivet (5) is an aluminum rivet.
The novel ruler that the utility model has a protractor set square not the time spent folding, as shown in Figure 1; Launch during use, as shown in Figure 2.Can use any instrument separately, other instrument is still collapsible, does not disturb mutually during use.
The foregoing description only is a preference of the present utility model, is not used for limiting the utility model, and all within principle of the present utility model, any modifications and variations of being done are all within protection domain of the present utility model.
