Abstract
The utility model relates to a kind of Multifunctional straightedge, comprise ruler body, on described ruler body, straight section is provided with graduation mark, the lower straight section of described ruler body is provided with 30 degree of angle-shaped grooves, miter angle shape groove, 60 degree of angle-shaped grooves and protractor successively, and described 30 degree of angle-shaped grooves, miter angle shape groove and 60 degree of angle-shaped grooves are all be made up of a straight section and a hypotenuse section; For straight plane, two ends are respectively tapered plane in the middle of the bottom surface of described ruler body.When needs picture straight line, tapered plane near ruler graduation mark is contacted with paper, then setting-out, when needs picture angle, contacts the tapered plane near angle-shaped groove with paper, then angle is drawn, convenient and swift, do not need to change ruler back and forth, and be easy to carry, by arranging inclined-plane, be conducive to keeping the clean of ruler.
Description
Technical field
The utility model relates to technical field of stationery, particularly relates to a kind of Multifunctional straightedge.
Background technology
Ruler uses widely in learning life, and existing ruler can only draw horizontal line, and structure function is single, can not draw angled line.Draw angled line and must use protractor or set square, chi must be looked for when therefore using, change chi, comparatively inconvenient during use.People wish to draw some conventional angles, as 30 degree, 45 degree, 60 degree with ruler always.Existing ruler is after setting-out simultaneously, and after particularly using pencil setting-out, the back side due to ruler is tightly fitted on paper, easily makes the vestige back side of ruler and paper occurring pencil, affect attractive in appearance.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of Multifunctional straightedge, use of ruler, set square and protractor being united, and can draw the angle that some are conventional, not need repeatedly to change.
The utility model is achieved through the following technical solutions:
A kind of Multifunctional straightedge, comprise ruler body, on described ruler body, straight section is provided with graduation mark, the lower straight section of described ruler body is provided with 30 degree of angle-shaped grooves, miter angle shape groove, 60 degree of angle-shaped grooves and protractor successively, and described 30 degree of angle-shaped grooves, miter angle shape groove and 60 degree of angle-shaped grooves are all be made up of a straight section and a hypotenuse section; For straight plane, two ends are respectively tapered plane in the middle of the bottom surface of described ruler body.
As optimal technical scheme of the present utility model, the left end centre position of described ruler body is provided with the lifting hole(eyelet) for hanging, and when not using ruler, is hung up.
As optimal technical scheme of the present utility model, the summit of described 30 degree of angle-shaped grooves, miter angle shape groove, 60 degree of angle-shaped grooves is all on same straight line.
As optimal technical scheme of the present utility model, the angle between described straight plane and tapered plane is 15-25 degree.
Compared with prior art, the beneficial effects of the utility model are: when needs picture straight line, are contacted by the tapered plane near ruler graduation mark, then setting-out with paper, when needs picture angle, tapered plane near angle-shaped groove is contacted with paper, then draws angle, convenient and swift, do not need to change ruler back and forth, and be easy to carry, by arranging inclined-plane, be conducive to keeping the clean of ruler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view in Fig. 1.
In figure: 1-ruler body; 2-graduation mark; 3-lifting hole(eyelet); 4-30 degree angle-shaped groove; 5-45 degree angle-shaped groove; 6-60 degree angle-shaped groove; 7-protractor; The straight plane of 10-; 11-tapered plane.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is the A-A sectional view in Fig. 1.
Described a kind of Multifunctional straightedge, comprise ruler body 1, on described ruler body 1, straight section is provided with graduation mark 2, the lower straight section of described ruler body 1 is provided with 30 degree of angle-shaped grooves 4, miter angle shape groove 5,60 degree of angle-shaped grooves 6 and protractor 7 successively, described 30 degree of angle-shaped grooves 4, miter angle shape groove 5 and 60 degree of angle-shaped grooves 6 are all be made up of a straight section and a hypotenuse section, and the summit of described 30 degree of angle-shaped grooves 4, miter angle shape groove 5,60 degree of angle-shaped grooves 6 is all on same straight line.
For straight plane 10, two ends are respectively tapered plane 11 in the middle of the bottom surface of described ruler body 1, the angle between described straight plane 10 and tapered plane 11 is 15-25 degree.When needs picture straight line, tapered plane 11 near ruler graduation mark is contacted with paper, then setting-out, when needs picture angle, contacts the tapered plane 11 near angle-shaped groove with paper, then angle is drawn, convenient and swift, do not need to change ruler back and forth, and be easy to carry, by arranging inclined-plane, be conducive to keeping the clean of ruler.
The left end centre position of described ruler body 1 is provided with the lifting hole(eyelet) 3 for hanging, and when not using ruler, is hung up.
When needing one, picture to be the lines of 30 degree with known line segment, the known line segment of the straight section of 30 degree of angle-shaped grooves 4 and this is overlapped, like this, the hypotenuse section of angle-shaped groove is inevitable is 30 degree with this known line segment, can draw known line segment with this along hypotenuse section is the lines of 30 degree, very easy to use like this, without the need to using set square or protractor, be conducive to improving answer speed.Other angles as: also can draw according to the method described above for 45 degree, 60 degree.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
