Abstract
The utility model discloses a multifunctional mathematical education scale, belonging to the field of teaching tools. The multifunctional mathematical education scale comprises a ruler, wherein a scale mark is arranged on the surface of the ruler, an angle ruler is connected with the bottom of one side of the ruler through a rotary shaft, and a semicircular angle scale is arranged on the surface of the ruler and is concentric with the rotary shaft; and compass legs are connected with the other side of the ruler through a hinge, a chalk sleeve is arranged at the bottom of each chalk sleeve, and a locating needle is arranged at the bottom of the ruler on one side of the chalk sleeve. Compared with prior art, the multifunctional mathematical education scale disclosed by the utility model has the characteristics of reasonable design, simple structure, easy processing, convenience for carrying and using, complete functions and the like, thus the education efficiency and the education quality of teachers are effectively improved.
Description
Technical field
The utility model relates to the educational aid field, the chi of multifunctional mathmatical teaching specifically.
Background technology
In how much mathematical educations, usually need picture straight line, triangle, circle and angle line; So ruler, set square, inclinometer etc. become the indispensable educational aid of math teacher teaching process; Because the educational aid function singleness, so that the teacher operates when drawing composite figure is very loaded down with trivial details, two hands of teacher are all occupied; Very inconvenient when on vertical blackboard, drawing, seriously influenced teacher's teaching efficient.
Summary of the invention
The technical assignment of the utility model is to above weak point, provides a kind of and can improve teacher's the efficiency of teaching and the multifunctional mathmatical teaching chi of quality of instruction.
The utility model solves the technical scheme that its technical problem adopted: this mathematical education chi comprises that the surface is provided with the ruler of graduation mark; The bottom of ruler one side is connected with bevel protractor through rotating shaft, and the surface of ruler is provided with the semicircle angle scale with the rotating shaft concentric; The opposite side of the ruler compass leg that has been connected through the hinge, the bottom of compass leg is provided with chalk sleeve, and the ruler bottom of chalk sleeve one side is provided with pilot pin.
Described semicircle angle scale is provided with angle indicator, angle indicator and bevel protractor coaxial rotation.
The multifunctional mathmatical of the utility model teaching chi is compared with prior art, have reasonable in design, simple in structure, be easy to processing, portably use convenience, characteristics such as multiple functional, effectively raise teacher's efficiency of teaching and quality of instruction.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of multifunctional mathmatical teaching chi.
Among the figure: 1, ruler, 2, compass leg, 3, bevel protractor, 4, angle scale, 5, angle indicator, 6, chalk sleeve, 7, pilot pin, 8, graduation mark, 9, rotating shaft.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The multifunctional mathmatical teaching chi of the utility model; Its structure comprises that the surface is provided with the ruler 1 of graduation mark 8; The bottom of ruler 1 one sides is connected with bevel protractor 3 through rotating shaft 9; The surface of ruler 1 is provided with the semicircle angle scale 4 with rotating shaft 9 concentrics, and semicircle angle scale 4 is provided with angle indicator 5, angle indicator 5 and bevel protractor 3 coaxial rotation; The opposite side of ruler 1 compass leg 2 that has been connected through the hinge, the bottom of compass leg 2 is provided with chalk sleeve 6, and ruler 1 bottom of chalk sleeve 6 one sides is provided with pilot pin 7.
Compass leg 2 and bevel protractor 3 are incorporated in ruler 1 place, can be used as ruler 1 this moment and use, when needs picture triangle or angle line, bevel protractor 3 can be drawn after ruler 1 turns to proper angle; When needs picture bowlder, ruler 1 vertical blackboard is used, the chalk clamping in chalk sleeve 6, is confirmed that through regulating compass leg 2 the radius of a circle size can the picture circle.
Its processing and fabricating of multifunctional mathmatical teaching chi of the utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
