Description
Technical field
A kind of drawing instrument that the utility model relates to is a kind of multi-functional triangular ruler specifically.
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 draw special figure, just must cooperate use by several instruments, it is cumbersome to map, spended time is many, error is bigger, and multiple instrument uses and carries all inconveniently, also is easy to lose one of them, brought many troubles to the user.
Though someone has designed some chis, be " multifunctional ruler " as the patent No. 99214494.9 designed patent names, it is to be made of protractor, connecting pin, set square, ruler.It is characterized in that at first, process protractor, set square and ruler with rigid plastics, in the intersection of protractor, set square and ruler connecting pin is installed then, is a kind of multifunctional ruler that has very much practical value.But the most structure of these instruments is numerous and diverse, and is very inconvenient in the use; The intersection of protractor, set square and ruler installs connecting pin and also takes off easily, and, do not draw the model of special graph, as five-pointed star, circle, trapezoidal etc., during drafting, need other instrument to cooperate, cumbersome, spended time is many, error is bigger, is not suitable for the student and uses.
Summary of the invention
The utility model provides a kind of special graph of carrying that has, and draws convenient, simple in structure multi-functional triangular ruler, has solved above-mentioned deficiency.
To achieve these goals, the utility model is to realize by the following technical solutions:
Multi-functional triangular ruler comprises set square; It is characterized in that be provided with semicircle protractor at the mid portion of described set square, described protractor and set square are combined into an integral body, are provided with hollow semicircle in the described semicircle protractor, are convenient to draw fan-shaped or semicircle; Be provided with the wave plate at described set square on one side, the other both sides of described set square indicate the length scale; On the set square of protractor bottom, establish circular port, tri-angle-holed, square hole, five-pointed star hole and trapezoidal hole, be convenient to draw special figure.
Also be provided with the lattice that are coated with of card-coating special use on the described set square, convenient in examination, utilize answer card-coatings such as 2B, 4B pencil.
The beneficial effects of the utility model are, because protractor of the present utility model is arranged in the set square, and on set square, be provided with the hole of drawing special graph, as circular port, tri-angle-holed, square hole, five-pointed star hole etc., it is convenient, simple in structure to draw, and is easy to make, cost is low; On set square, also be provided with the special use of scribbling answering card and be coated with lattice, practical, quick, easy to carry, realized the drawing instrument multifunctional all.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, multi-functional triangular ruler is to be provided with the integral body that protractor 1 and set square are combined in set square 1, this set square 1 can be drawing square, also can be the equilateral triangle chi, in protractor 2, made hollow semicirclely 3, be convenient to draw fan-shaped or semicircle; The base of this protractor 2 is one side of set square 1, and on the set square 1 under protractor 2 bases, made special graph spaces such as circular port, tri-angle-holed, square hole, five-pointed star hole and trapezoidal hole, draw pairing special graph by this special graph space.Be provided with wave molding plate 4 on one side of set square 1, described set square 1 other both sides indicate the length scale; In the present embodiment, it is on the protractor base that wave plate 4 is arranged on the hypotenuse of set square, draws wave by wave plate 4.
In the utility model, set square 1 make on one side be coated with that answering card uses be coated with lattice 5, in the present embodiment, be coated with the corner location that compare on both sides that lattice 5 are arranged on set square, be convenient to the examinee and utilize and be coated with lattice 5 and scribble answering card fast.
The utility model in use, two right-angle sides of useful set square are made form, take measurement of an angle with protractor 2, utilize hollow semicircle 3 to draw fan-shaped or semicircle, draw some special graphs with set square, circle, five-pointed star, the trapezoidal grade, the inconvenience that this utility model has avoided multiple instrument to use and carry has been brought many troubles to the user.In addition, when regular examination, spendable 2B, pencils such as 4 are scribbled answering card by being coated with lattice, fast, convenient.
Because protractor of the present utility model is arranged in the set square, and on set square, be provided with the hole of drawing special graph, as circular port, tri-angle-holed, square hole, five-pointed star hole etc., it is convenient, simple in structure to draw, be easy to make, cost is low, practical, easy to carry, realized the drawing instrument multifunctional all.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
