Abstract
The utility model relates to a multifunctional math teaching aid, belongs to a drawing tool and mainly solves the problem that a conventional teaching aid is inconvenient to use when being used for drawing on a blackboard. The multifunctional math teaching aid structurally comprises two supporting legs and a rotating shaft; one ends of the two supporting legs are hinged by a rotating shaft; two set squares are respectively arranged on the same lateral surfaces of the two supporting legs; one side edges of the set squares are provided with scale lines; the tail end of one supporting leg is provided with a powerful magnetic head; and the tail end of the other supporting leg is provided with a chalk. The math teaching aid integrates functions of a ruler, compasses and the like into one whole body and is very convenient to use and carry.
Description
Technical field
The utility model relates to a kind of drawing instrument, specifically a kind of multifunctional mathmatical teaching aid.
Background technology
In the teaching of math teacher, for the ease of the principle and the notion of students understand and memory drawing, teacher uses instruments such as ruler, compasses on blackboard, to draw and measure through regular meeting; This just need be by the teaching aid of special use, but traditional ruler, protractor and compasses etc. are independently, gets into the classroom so teacher before class has to carry various teaching aids; Very inconvenient; In addition, using compasses to draw that an end (being the center of circle) that must guarantee to have pin in the process of circle can not move and two foot distance leaves (being radius) and can not change, but owing to the blackboard surface is harder and smooth; The stitch of compasses partly is difficult to fixing; Move easily the position, and promptly the center of circle is difficult to confirm, so can influence the accuracy and the effect of picture.
The utility model content
The purpose of the utility model is to provide a kind of multifunctional mathmatical teaching aid, and this teaching aid integrates functions such as ruler, compasses and uses and carry all convenient.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of multifunctional mathmatical teaching aid; Its structure comprises two supporting legs and rotating shaft; Described two supporting leg one ends are hinged through rotating shaft, are respectively arranged with a set square in the same side of two supporting legs, and a side of described set square is provided with graduation mark; The end of one of them supporting leg is provided with powerful magnetic head, and the end of another supporting leg is provided with chalk.
The beneficial effect of the utility model is: during use, select the drawing and the measurement function of teaching aid as required arbitrarily, like need picture bowlder; Can powerful magnetic head be adsorbed on the blackboard that has magnetic, adjust the opening angle of two rulers, with powerful magnetic head as the center of circle; Utilize chalk on blackboard, to draw, the through hole of rotating shaft place can hang over teaching aid on the wall, fractures and damages preventing; Do not take up room, be convenient to take; The utility model is simple in structure, and use flexibly, conveniently can effectively be improved drawing efficiency on the blackboard.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 rotating shaft, 2 three-use rulers, 3 powerful magnetic heads, 4 chalks, 5 supporting legs.
The specific embodiment
As shown in Figure 1.A kind of multifunctional mathmatical teaching aid; Its structure comprises two supporting legs 5 and rotating shaft 1; Described two supporting leg 5 one ends are hinged through rotating shaft 1, are respectively arranged with a set square 2 in the same side of two supporting legs 5, and a side of described set square 2 is provided with graduation mark; The end of one of them supporting leg 5 is provided with powerful magnetic head 3, and the end of another supporting leg 5 is provided with chalk 4.
During use, select the drawing and the measurement function of teaching aid as required arbitrarily, like need picture bowlder; Can powerful magnetic head 3 be adsorbed on the blackboard that has magnetic, adjust the opening angle of two supporting legs 5, with powerful magnetic head 3 as the center of circle; Utilize chalk 4 on blackboard, to draw, the through hole at rotating shaft 1 place can hang over teaching aid on the wall, fractures and damages preventing; Do not take up room, be convenient to take; The utility model is simple in structure, and use flexibly, conveniently can effectively be improved drawing efficiency on the blackboard.
