Abstract

The utility model discloses to a multifunction ruler, relating to a drawing tool and in particular to a students use drawing ruler, which consists of a main scale (1), a minor scale (2) and a rolling axle (3). Wherein, the lateral on the left end of the main scale (1) has an angular measuring ruler plate (1.1), the upper part of which is a circular arc (1.5) that is higher than the straight edge (1.6) on the right upper part of the main scale (1). The angular measuring ruler plate (1.1) is integrated together with the main scale (1). The central position of the angular measuring ruler plate (1.1) with the angular scale is provided with the rolling axle (3). The minor scale (2) is pin jointed with the main scale (1) through the rolling axle (3) and the upper part of the minor scale (2) is an indicating pin (2.1). When needing to be placed into the stationery box, the students only need to rotate the minor scale (2) to be in superstition with the main scale (1). The utility model has the advantages of simple structure, easy and convenient application, cheap price, small space taking up, convenient taking and multifunction, etc.

Description

A kind of multifunctional ruler

Technical field: the utility model relates to a kind of drawing instrument, is specifically related to the drawing rule that a kind of student uses.

Background technology: the various drawing instruments that the student uses on the existing market are very many.Drawing instrument commonly used has ruler, set square, protractor etc., but these instrumental functions are single, only can be used for picture straight line, specific angle or take measurement of an angle, if will paint the figure of special angle, just must cooperate use by several instruments, it is cumbersome to map, and the time of cost is more, error is bigger, and many instruments carry very inconvenient.The many drawing instruments of some functions are also arranged on the existing market, but the most complex structure of these instruments is bulky not portable, great majority are put to advance student's writing case at all, and complicated operation, and are very inconvenient in the use; The most price of these drawing instruments is higher, is not suitable for the student and uses; And drawing instrument function simple in structure, that price is cheap very little.

The utility model content: the student that the utility model developed a kind of simple in structure, easy to use, low price, it is little to take up space, be convenient for carrying, function is many uses multifunctional ruler.The utility model is made up of main scale 1, secondary chi 2, rotating shaft 3, left end one side of main scale 1 is provided with an angle square plate 1-1, the top of angle square plate 1-1 is circular arc 1-5, circular arc 1-5 exceeds the straight flange 1-6 of main scale 1, angle square plate 1-1 and main scale 1 are structure as a whole, the center of angle square plate 1-1 is equipped with rotating shaft 3, and secondary chi 2 is hinged by rotating shaft 3 and main scale 1, and the upper end of secondary chi 2 is pointer 2-1.The utility model by revolute pair chi 2, can be made angle at any angle in use, and right angle, 30 ° of angles, 60 ° of angles, 45s all can be made, and replaced set square fully, and main scale 1 can be worked as ruler usefulness, and angle square plate 1-1 can work as protractor again and use; When needing the angle of picture certain angle, only need point to the angle that needs with the right side bearing of the pointer 2-1 of the upper end of secondary chi 2, and then the angle of being made by main scale 1 and secondary chi 2 is needed angle; When putting into writing case, needs only need secondary chi 2 forwarded to overlap with main scale 1 to get final product.The utlity model has simple in structure, easy to use, low price, take up space little, be convenient for carrying, advantage that function is many.

Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the B-B cutaway view of Fig. 1, and Fig. 4 is the C-C cutaway view of Fig. 1, and Fig. 5 is the D-D cutaway view of Fig. 1.

The specific embodiment one: this specific embodiment is made up of main scale 1, secondary chi 2, rotating shaft 3, left end one side of main scale 1 is provided with an angle square plate 1-1, the top of angle square plate 1-1 is circular arc 1-5, circular arc 1-5 exceeds the straight flange 1-6 of main scale 1, angle square plate 1-1 and main scale 1 are structure as a whole, the center of angle square plate 1-1 is equipped with rotating shaft 3, secondary chi 2 is hinged by rotating shaft 3 and main scale 1, the upper end of secondary chi 2 is pointer 2-1, pointer 2-1 is an angular structure, the vertical center line of the right edge of pointer 2-1 and secondary chi 2 coincides, and the limit, left side of pointer 2-1 is a hypotenuse.Two long straight flanges of described main scale 1 and secondary chi 2 all are carved with length graduation mark 1-3.Be carved with angle index number and graduation mark 1-4 on the described angle square plate 1-1 from 0-180 °.On the both sides of two long straight flanges of described main scale 1 chamfering 1-3 is arranged all, all there is chamfering 2-3 on the both sides on two long straight flanges of secondary chi 2.When can making the utility model use, the chamfering that increases is not stained with ink.

The specific embodiment two: the difference of this specific embodiment and the specific embodiment one is to be provided with the circular hole 1-2 that several vary in size between the lower edge on the right of main scale 1.Several circular holes 1-2 that increases can make the circle that varies in size easily, has made things convenient for use.Other composition is identical with the specific embodiment one with annexation.

The specific embodiment three: the difference of this specific embodiment and the specific embodiment one, two is that the middle part of angle square plate 1-1 is carved with 0-90 ° angle index number and graduation mark 1-7 respectively to both sides by the centre.This has also made things convenient for use.Other composition is identical with the specific embodiment one, two with annexation.

The specific embodiment four: shown in Fig. 4,5, this specific embodiment is that with the difference of the specific embodiment one, two, three inboard of 0 °, 30 °, 45 °, 60 °, 90 °, 120 °, 135 °, 150 °, 180 ° the graduation mark of angle square plate 1-1 is respectively equipped with a little pit 1-1-1, and the pointer 2-1 of corresponding secondary chi 2 goes up corresponding position and is provided with a boss 2-1-1.Pit 1-1-1 and boss 2-1-1 that present embodiment increases when doing some angles commonly used, are used to locate very convenient, make that also the angle error of making is less.Other composition is identical with the specific embodiment one, two, three with annexation.
