Abstract
The utility model discloses a gauge combination, which comprises a protractor and a right-angle set square. The protractor is provided with angle graduations, and two right-angle edges of the right-angle set square are provided with length graduations. The gauge combination is characterized by further comprising a hinge and a string, the left bottom corner of the protractor and the apex of the right angle of the right-angle set square are hinged on the hinge, a chalk sleeve is arranged at the right bottom corner of the protractor, a chalk is fixed in the chalk sleeve, and a rotary support leg is fixed at the right end of the right-angle edge of the right-angle set square adjacent to the protractor. The hinge is provided with a round hole, and the string is tied on the hinge after penetrating through the round hole. The gauge combination has the advantages of firstly simple structure, secondly multiple functions of measuring and drawing and thirdly convenience in carrying by the aid of the string.
Description
Technical field
The utility model relates to a kind of mathematical education apparatus, particularly a kind of combination ruler.
Background technology
In the mathematical education practice, teacher often needs drawing instruments such as ruler, compasses, protractor, set square, but existing these teaching aids only have single function at present; Thereby; Teacher is at school the time, and these several kinds of drawing instruments all need carry, if leave behind a certain drawing instrument; Then can delay teaching process, thus very inconvenient.
Summary of the invention
The problem that the utility model will solve is: a kind of simple in structure, combination ruler of being easy to carry and having multiple function is provided.
In order to solve the problems of the technologies described above; The combination ruler of the utility model comprises protractor and right angle triangle, and said protractor is provided with angle index; Two right-angle sides of said right angle triangle are provided with the length scale; It is characterized in that: also comprise an articulated body, said protractor the lower left corner and the summit, right angle of right angle triangle be hinged on the articulated body, the lower right corner of said protractor is fixed with a chalk sleeve; Be fixed with chalk in the said chalk sleeve, the right-hand member of the right-angle side that said right angle triangle and protractor are adjacent is fixed with a rotation leg.
For the ease of carrying, the combination ruler of the utility model also comprises a tethers, and said articulated body is provided with a circular hole, and said tether binds on articulated body after passing circular hole.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) comprise protractor and right angle triangle, the right-angle side of right angle triangle is provided with the length scale, thus have take measurement of an angle, measure length and and the function of drawing right angled triangle; (3) protractor the lower left corner and the summit, right angle of support set square be hinged on the articulated body; The lower right corner of protractor is fixed with a chalk sleeve; The right-hand member of the right-angle side that right angle triangle and protractor are adjacent is fixed with a rotation leg, thereby the rotation articulated body, and chalk is rotated along the rotation leg; Can accomplish round drafting, have the function of compasses; (4) be provided with tether, when carrying, mention tether and get final product, thereby be easy to carry.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, protractor, 2, angle index, 3, chalk sleeve, 4, chalk, 5, the rotation leg, 6, the length scale, 7, right angle triangle, 8, articulated body, 9, circular hole, 10, tether.
The specific embodiment
As shown in Figure 1; The combination ruler of the utility model comprises protractor 1 and right angle triangle 7, and said protractor 1 is provided with angle index 2; Two right-angle sides of said right angle triangle 7 are provided with length scale 6; Also comprise an articulated body 8, said protractor 1 the lower left corner and the summit, right angle of right angle triangle 7 be hinged on the articulated body 8, the lower right corner of said protractor 1 is fixed with a chalk sleeve 3; Be fixed with chalk 4 in the said chalk sleeve 3, the right-hand member of the right-angle side that said right angle triangle 7 and protractor 1 are adjacent is fixed with a rotation leg 5; Also comprise a tethers 10, said articulated body 8 is provided with a circular hole 9, and said tether 10 binds on articulated body 8 after passing circular hole 9.
The combination ruler of the utility model has the function that takes measurement of an angle, the function of measuring length, the function of drawing right angled triangle and the function of draw circles, thereby diverse in function, uses easily.
The combination ruler of the utility model is provided with tether 10, when carrying, mentions tether 10 and gets final product, thereby be easy to carry.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
