Abstract
The invention relates to a multifunctional ruler which comprises a ruler shell, a circular transparent cover and a ball. The ruler shell is provided with a circular groove at the center. The ball is set in the circular groove and rolls in the circular groove under the action of gravity to determine the angle. The circular transparent cover concentric with the circular groove is fitted on the upper surface of the ruler shell. The whole peripheral edge of the circular transparent cover is provided with angle scale. The circular transparent cover with arc section is capable of magnifying to allow the position of the ball to be conveniently observed. The multifunctional ruler is applicable to drawing and measuring of lines of any angles, and is multifunctional, simple to operate and highly accurate.
Description
Technical field
The present invention relates to the multi-functional ruler of the angular surveying of a kind of drafting that realizes the drafting of arbitrarily angled straight line, arbitrarily angled straight line parallel line and arbitrarily angled straight line.
Background technology
The use of ruler in daily life and Graphing of Engineering is very general, especially in Graphing of Engineering, drawing aid miscellaneous is numerous and complicated various, as ruler, set square, protractor, T-square etc., but with regard to assisted mapping, these instruments show slightly loaded down with trivial details, and there is function overlapping each other, for example: the function of set square is the straight line of drawing at an angle, as 90 degree, 30 degree, 45 degree, 60 degree etc., the function of protractor is to measure certain angle, and the function of ruler is to draw straight line, and the function of T-square is the straight line that can draw with the chart board frame perpendicular.These instruments often can not use separately, but need cooperation each other, and for example: when drafting is the straight line of non-90 degree angles with the chart board frame, need use T-square, ruler and protractor, very inconvenient, making draws becomes complicated, and expends time in.
Summary of the invention
At above problem, a kind of multi-functional ruler is proposed, based on the gravity sensing principle, realize drafting and the measurement of arbitrarily angled straight line.Simple to operate and accuracy is high.
Basic technical scheme is: the composition of multi-functional ruler comprises: ruler housing, annular transparency cover and ball.The ruler housing is rectangle, and an end is printed on the scale of expression length, and toroidal cavity is carved with in ruler housing center, is printed on the scale of expression angle on the toroidal cavity outer ring, and a ball is arranged in the toroidal cavity.Ball diameter is slightly less than the toroidal cavity diameter, makes ball to be acted in the toroidal cavity by gravity and rolls, and is used for determining of angle.Ruler housing upper surface is furnished with the annular transparency cover, and the cross section of annular transparency cover is curved, has amplification effect, the convenient position of observing ball.
The invention has the beneficial effects as follows:
1. the present invention is ruler, protractor, set square, T-square, and multiple drawing survey tool such as compasses organically combines, and realizes the many usefulness of a chi, and is easy to use and be easy to carry;
2. application of weight principle of induction of the present invention makes ruler to find horizontal reference fast, has reduced the drawing time, measures more accurate.
3. the present invention uses earth gravitational field to seek mode as benchmark, and manufacturing process is simple, and required cost is low, is easy to promote.

The specific embodiment
Further specify concrete structure of the present invention and embodiment below in conjunction with accompanying drawing.
Structure of the present invention is formed as Fig. 1, Fig. 2, shown in Figure 3.Its composition comprises: ruler housing (1), annular transparency cover (2) and ball (3).Ruler housing (1) is rectangle, and an end is printed on the scale of expression length, and toroidal cavity (4) is carved with in ruler housing (1) center, is printed on the scale of expression angle on toroidal cavity (4) outer ring, and a ball (3) is arranged in the toroidal cavity (4).Ball (3) diameter is slightly less than toroidal cavity (4) diameter, makes ball (3) to roll in toroidal cavity (4).Ruler housing (1) upper surface is furnished with annular transparency cover (2), and annular transparency cover (2) cross section is curved, has amplification effect, the convenient position of observing ball.
Use of the present invention is as follows:
In the time of need drawing at any angle straight line, earlier that the present invention is flat by on tilted-putted drawing, move to the position that needs to draw straight line.End by tight ruler housing (1) is adjacent to drawing and slowly rotates ruler housing (1), and the ball (3) in the toroidal cavity (4) can be rolled into minimum point under the effect of gravity on the ruler in toroidal cavity (4) at this moment.See through annular transparency cover (2) and observe the angle index of ball (3) stop place correspondence.When ball (3) rested on the scale of straight line angle of required drafting, the ruler housing (1) that stops operating had one side of length scale to draw the straight line of Len req and angle along ruler housing (1).
When needing to measure the angle of arbitrarily angled straight line, earlier that the present invention is flat by on tilted-putted drawing, move to the position of the straight line that need take measurement of an angle.Be adjacent to drawing rotation ruler housing (1), seek correct position, make ruler housing (1) one side the straight line place that has accurately snapping to of length scale to take measurement of an angle.Ball (3) in the toroidal cavity of the present invention this moment (4) can be rolled into minimum point under the effect of gravity in toroidal cavity (4).Observing the angle index of ball (3) stop place correspondence by annular transparency cover (2), both had been the angle between required measurement straight line and the horizontal line.
When need drawing arbitrarily angled PAR, used method is measured the current angle of straight line during earlier with the angle of the arbitrarily angled straight line of measurement, write down the position of ball (3), again when drawing straight line at any angle used method draw one with the intersecting lens that becomes an angle of 90 degrees to boning out, as being offset boost line.Be datum mark with the intersection point of giving boning out and skew boost line, according to shift value one end of ruler housing (1) is snapped to and to determine another end points on the boost line, there is one side of length scale to move on to this end points ruler housing (1), rotation ruler housing (1), make ball (3) rest on the position identical with providing straight line, the ruler housing (1) that stops operating has one side of length scale can draw out and provide the straight line that the rectilinear translation value is determined along ruler housing (1).
Claims (1)
1. multi-functional ruler, its composition comprises: ruler housing, annular transparency cover and ball; It is characterized in that: toroidal cavity is carved with in described ruler housing center, a ball is arranged in the toroidal cavity, ball rolls because gravity acts in the toroidal cavity, be used for determining of angle, ruler housing upper surface is furnished with the annular transparency cover concentric with toroidal cavity, and annular transparency cover edge complete cycle has the scale of expression angle; The cross section of described annular transparency cover is curved, has amplification effect, the convenient position of observing ball; Described multi-functional ruler can realize that the drafting of arbitrarily angled straight line, arbitrarily angled PAR are drawn and the angular surveying of arbitrarily angled straight line.
