Abstract

The utility model discloses a multifunctional scribing ruler which is used for scribing, mapping, and measuring angles. The multifunctional scribing ruler which is used for scribing, mapping, and measuring angles is composed of a straight ruler and a protractor which is vertical to the straight ruler. The multifunctional scribing ruler which is used for scribing, mapping, and measuring angles is characterized in that various figures are arranged on the plane of the straight ruler. The multifunctional scribing ruler which is used for scribing, mapping, and measuring angles can be used for drawing a round, a rhombus, a rectangle, a plane tetragon, a sine curve, a cosine curve, and the simple symbol of an electronic component. The straight ruler and the protractor are an integral body. The multifunctional scribing ruler which is used for scribing, mapping, and measuring angles is molded into by using polyvinylchloride. The utility model has the advantages of convenient operation and strong practicability, and is suitable for middle and primary school students.

Description

Multifunctional template ruler

The utility model belongs to a kind of marking-out rule, more properly says it is the multi-functional marking-out rule of the line of a kind of energy, mapping and angulation.

Student stationery is as commercializations already such as: ruler, protractor, garden rule and T-squares, but comprehensive above stationery function also be not commercially available the multi-functional marking-out rule that it becomes a chi up to now.Vast primary and secondary students are figure everyday, line is carried above stationery respectively and not only bothered, and the more important thing is and use above stationery to do many times that figure, line will slattern the student respectively, and also standard not too of the figure that marks.

The multipurpose ruler that provides a kind of multi-functional student of being convenient to carry is provided the purpose of this utility model.

The utility model provides a kind of multi-functional marking-out rule, the garden that it is characterized in that on the plane of ruler, having two different-diameters that it is made up of a ruler and a protractor vertical with ruler, hollow prismatic, hollow rectangle, one just, cosine curve and 1-5 hollow electronic component symbol, except hollow electronic component outer symbol, the axis of above-mentioned other figure and coincides with the center line of ruler all on same straight line.

Utilize the hollow garden of two different-diameters on this chi, except drawing the garden, also can draw the inside and outside of two gardens and cut, intersect and garden circumscribed triangle figures in two gardens or many gardens, utilizes hollow prismatic except drawing prismatic figure, can also draw equilateral, isosceles triangle.Utilize hollow rectangle except drawing rectangular figure, can also draw trapezoidal and drift angle is the right angled triangles of 30 degree.Utilize hollow parallelogram, except drawing parallelogram, can also draw acute angle and triangle etc.Utilize hollow sine and cosine curvilinear figure can mark standard just, cosine curve figure.Utilize hollow electronic component symbol can mark better simply electronic devices and components figure.Utilize this chi also can draw parallel lines, line segment and straight line etc.Be marked with centimetre being the scale of unit at the vertical edge of ruler.

Another feature of the present utility model is on the ruler top, and a protractor is arranged on the position vertical with ruler, and its center of circle is on the ruler plane on 0.Curved edge at protractor is marked with angle index, and this protractor can be used to take measurement of an angle and marks different angles.

This chi can form with the polyvinyl chloride mold pressing, and is therefore cheap, practical, is suitable for students in middle and primary schools and uses.

Diagram: accompanying drawing 1 is a floor map of the present utility model.

Accompanying drawing 2 is the figure of cuing open of the present utility model, and wherein 1 is the graduation mark of ruler; 2 is small circular; 3 is big circles; 4 is that electronic devices and components meet; 5 is prismatics; 6 is rectangles; 7 is flat shape quadrangles; 8 be one just, cosine curve; 9 is protractors; The 10th, the center of circle of protractor.

Claims

1, a kind of by a ruler and one perpendicular to the multi-functional marking-out rule that the protractor of ruler constitutes, it is characterized in that on the plane of ruler, having the hollow garden of two different-diameters, hollow prismatic, hollow rectangle, one just, cosine curve and 1-5 hollow electronic component symbol.Except the electronic component outer symbol, more than the axis of other figure all on same straight line, and with the central lines of ruler.

2, according to the described multi-functional marking-out rule of claim 1, it is characterized in that being marked with centimetre being the scale of unit at ruler, 0 starting point of scale is on the ruler position vertical with protractor.

3, according to the described multi-functional marking-out rule of claim 1, it is characterized in that one protractor being arranged on the ruler top, its garden heart is on the ruler plane on 0

4, according to the described multi-functional marking-out rule of claim 1, it is characterized in that ruler and angulation are an integral body, available polyvinyl chloride mold pressing forms.
