Abstract
The utility model discloses a kind of multi-functional combination drawing tool, comprise the first ruler, the second ruler and protractor, the starting point of standard scale of described first ruler, the second ruler overlaps with the center of circle of protractor, and hinged by the connector with positioning through hole; First ruler is provided with along its length have free sliding degree, with the slide block of pairs of bit line, slide block is provided with the tapered through hole concordant with the first ruler edge.The utility model structure is simple, only can be realized the basic function of ruler, set square, protractor and compasses by two rulers and 1 protractor, and solves the more defect of set square and compasses tip, not only light but also firmly, long service life.
Description
Technical field
The utility model relates to the drawing appliance in study and work, is specifically related to a kind of multi-functional combination drawing tool, integrates the function of set square, ruler, protractor and compasses.
Background technology
In study and work, often need to draw line segment, angle, circular arc, plane or even stereogram, need by conventional tool such as ruler, compasses, set square and protractors.Existing above-mentioned drawing instrument is all generally independently single-piece, and number of packages is many, and wedge angle is many, carries and take care of to have difficulties, and spends also high.Also there is following defect: 1. low precision, when especially coordinating picture triangle with ruler with protractor, and during circular arc by compasses picture certain radian, wherein the angle of circular arc is not easy control; 2. plotting speed is slow, because usually need multiple types of tools to cooperatively interact; 3. resource is wasted, each measurer function singleness, can not one-object-many-purposes, use loaded down with trivial details.
Chinese patent 98230655.5 discloses a kind of multipurpose stationery, and be made up of two chi sheets, one end of a chi is designed to protractor, and two chi sheets are connected to form angle gauge by screw-button, arranges wedge angle and the nib of picture circle at the free end of two chis.Although such scheme can draw the triangle of certain size, the circle of certain radius value or the drafting of circular arc are still very loaded down with trivial details, and still there is the defect that above-mentioned wedge angle is many, plotting speed is slow.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of precision is high, service efficiency is high, is easy to carry about with one, lower-cost multi-functional combination drawing tool, not only gathered the repertoire of set square, ruler, protractor and compasses, and structure is simple, easy to use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of multi-functional combination drawing tool, comprise the first ruler, the second ruler and protractor, the starting point of standard scale of described first ruler, the second ruler overlaps with the center of circle of protractor, and hinged by the connector with positioning through hole; First ruler is provided with along its length have free sliding degree, with the slide block of pairs of bit line, slide block is provided with the tapered through hole concordant with the first ruler edge.
In upper technical scheme, the triangle of any angle and accurate dimension and the circular arc of any radian, the drafting of line segment can be realized, have the function of T-square, ruler, set square, protractor and compasses concurrently.
The beneficial effect adopting technique scheme to produce is: (1) the utility model structure is simple, the basic function of ruler, set square, protractor and compasses only can be realized by two rulers and 1 protractor, and solve the more defect of set square and compasses tip, not only light but also firm, long service life; (2) carry out as required combining, splitting use, the drafting precision of angle is covered 0 ~ 360 °, in further improved plan, the size of ruler can also be extended, expand its scope of application.

Detailed description of the invention
A specific embodiment of the present utility model see Fig. 1.It comprises the first ruler 4, second ruler 6 and protractor 1, and the starting point of the standard scale of described first ruler 4, second ruler 6 overlaps with the center of circle of protractor 1, and hinged by the connector 7 with positioning through hole; First ruler 4 is provided with along its length have free sliding degree, with the slide block 2 of pairs of bit line, slide block 2 is provided with the tapered through hole 5 concordant with the first ruler 4 edge.Described connector 7 is the jointed shaft of the positioning through hole with taper.
In this embodiment, the method of drawing line segment is apparent, draw concrete angle and the leg-of-mutton method of length is: first utilize the second ruler 6 to draw a leg-of-mutton limit of specific length, then this limit end points is overlapped with the center of circle of protractor 1, first ruler 4 is rotated the angle to setting, along the first ruler 4 setting-out to specific length, finally line segment head and the tail are connected.
Draw the method for circular arc: see Fig. 2, rotated a certain angle by the first ruler 4, slide block 2 is slid into the length of setting, make the pairs of bit line on slide block 2 and the label alignment on the first ruler 4; Then located by drawing instrument with the positioning through hole of pencil by connector 7, left hand fixes pencil and the second ruler, and the right hand takes pencil to rotate through the direction of the conical through-hole 5 on slide block 2 to the second ruler 6, can complete the drafting of circular arc.
Described slide block 2 is also provided with the hand-tight bolt 3 in location, with position limiting slide block 2, the precision ensureing drawing, in use by hand-tight bolt 3, slide block and the first ruler 4 is located.The structural representation of slide block 2 and the first ruler 4 is see Fig. 5.Conical through-hole 5 is suitable with the cutting profile of pencil.
In another embodiment, see Fig. 3, the first ruler 4 and the second ruler 6 are respectively equipped with chute 8, in the below of the first ruler 4 and the second ruler 6, are connected to extension chi 9 by pass through the riveting axle of chute 8.The offside of extension chi 9 graduation mark is respectively equipped with the chute corresponding with the side of the first ruler 4 and the second ruler 6.
In sum, the utility model can be drawn line segment, determines the triangle of angle and length, determines the camber line of angle and determine the circle etc. of diameter.
