Abstract
The utility model discloses a mathematics teaching ruler. The mathematics teaching ruler comprises a ruler, wherein a protractor is integrally connected at one end of the ruler, a circle drawing ruler is rotatably connected at the other end of the ruler, a movable ruler is rotatably connected in the circle center position of the protractor, and a set square is rotatably connected in the central position of the protractor through a rotatable arm. The mathematics teaching ruler has a simple structure, is convenient to carry and use, can improve the drawing efficiency of teachers, conveniently measure various angles with the protractor, draw an angle through the movable ruler after the angle measurement, conveniently draw a triangle with the set square, and draw a circle by rotating the circle drawing ruler after the chalk is put in the chalk holder.
Description
Technical field
The utility model relates to a kind of mathematical education apparatus, is a kind of mathematical education chi specifically.
Background technology
At present, the drawing tools that the teacher uses in teaching process mainly contains ruler, set square, compasses, protractor etc., and its shortcoming is: the purposes of every kind of drawing tools is single, carry inconvenience, and to use respectively, when drawing, need change drawing instrument frequently, reduce efficiency of teaching.If draw specific angle, just must match with protractor and ruler and just can finish, it is very loaded down with trivial details to operate like this, has increased teacher's workload.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of simple in structure, carry with easy to use, can improve the mathematical education chi of teacher's drawing efficiency.
For addressing the above problem, the utility model by the following technical solutions:
A kind of mathematical education chi, comprise ruler, a wherein end of described ruler is connected with protractor, and the other end of described ruler is rotatably connected to picture circle chi, the home position of described protractor is rotatably connected to adjustable rule, and the center of described protractor is rotatably connected to set square by pivoted arm.
Below be further improvement of the utility model:
Slidely connect slide block on the described picture circle chi, described slide block is provided with chalk sleeve, and described slide block is provided with trip bolt.
Further improve:
Be respectively equipped with scale on described adjustable rule, the picture circle chi.
The utility model adopts technique scheme, simple in structure, carry with easy to use, can improve teacher's drawing efficiency, the throughput hornwork can be convenient for measuring various angles, can draw the angle by adjustable rule after measuring angle, arranging of set square can conveniently be drawn triangle, can draw circle by rotating picture circle chi behind the chalk of packing in chalk sleeve.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: the 1-ruler; The 2-protractor; The 3-adjustable rule; 4-draws the circle chi; The 5-slide block; The 6-chalk sleeve; The 7-trip bolt; The 8-pivoted arm; The 9-set square.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of mathematical education chi, comprise ruler 1, a wherein end of described ruler is connected with protractor 2, the other end of described ruler 1 is rotatably connected to picture circle chi 4, and the home position of described protractor 2 is rotatably connected to adjustable rule 3, and the center of described protractor 2 is rotatably connected to set square 9 by pivoted arm 8.
Slidely connect slide block 5 on the described picture circle chi 4, described slide block 5 is provided with chalk sleeve 6, and described slide block 5 is provided with trip bolt 7, and described slide block 5 can be fixing with picture circle chi 4 by trip bolt 7.
Be respectively equipped with scale on described adjustable rule 3, the picture circle chi 4.
