Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of multifunctional mathmatical teaching aid.
Background technology
At present, in the mathematical education process, math teacher need be used many apparatus; As, when drawing straight line, need use ruler, need use compasses at the picture bowlder; When taking measurement of an angle, need use angel measuring instrument, draw the angle of certain angle if desired, just must match and to accomplish with angel measuring instrument and ruler; Also will use set square in many cases, these teaching aids generally disperse to place, and math teacher need be brought all various apparatus when giving lessons; Not only carry inconvenience, and in a rush when giving lessons, influence efficiency of teaching easily.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of the utility model is to provide, and is convenient for carrying and uses, and integrates functions as one, and can alleviate teacher's burden, and can effectively improve the multifunctional mathmatical teaching aid of efficiency of teaching.
In order to reach above purpose; The technical scheme that the utility model adopted is: the multifunctional mathmatical teaching aid; Comprise ruler; It is characterized in that: an end of said ruler rotates and is provided with rotary ruler and angel measuring instrument, and said ruler and rotary ruler are provided with the angle regulator that is used to regulate and fix angle between said ruler and the rotary ruler, and the free end of said ruler and rotary ruler is equipped with the chalk sleeve that is used to install chalk.
Said angle regulator comprises that slip chi that the middle part has a chute stretches out said chute and with said slip chi fixed fastening screw with being fixedly installed on said ruler and the rotary ruler.
Said ruler and rotary ruler are provided with scale.
The beneficial effect of the utility model is: simple in structure, reasonable in design, and be convenient for carrying and use, integrate functions as one, teacher's burden can be alleviated, and efficiency of teaching can be effectively improved.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
Shown in accompanying drawing; The multifunctional mathmatical teaching aid; Comprise ruler 1; One end of said ruler 1 rotates and is provided with rotary ruler 2 and angel measuring instrument 3, and said ruler 1 and rotary ruler 2 are provided with the angle regulator that is used to regulate and fix angle between said ruler 1 and the rotary ruler 2, and the free end of said ruler 1 and rotary ruler 2 is equipped with the chalk sleeve 4 that is used to install chalk.Can regulate the angle between ruler 1 and the rotary ruler 2 through angle regulator, thereby the angle of convenient portrayal multiple angles is easy to use; Utilize ruler 1, rotary ruler 2 and pass through the chalk in the chalk sleeve 4, can portray the circle of different radii, easy to use, can alleviate teacher's burden.
Said angle regulator comprises that slip chi 6 that the middle part has a chute 5 stretches out said chute 5 on said ruler 1 and the rotary ruler 2 and with said slip chi 6 fixed fastening screws 7 with being fixedly installed on.Rotary ruler 2 can rotate with respect to ruler 1 along slip chi 6; When turning to suitable angle; Through trip bolt 7 slip chi 6 and ruler 1 and rotary ruler 2 are fixed, thus the various angles of convenient adjusting, and can measure suitable radius or diameter according to this mode; Fixedly picture is round, easy to use with respect to ruler 1 to make rotary ruler 2.
Said ruler 1 is provided with scale 8 with rotary ruler 2.Can realize the measurement function of ruler through scale 8.
When needing the angle of picture different angles, the certain angle of angel measuring instrument 3 measurements capable of using makes ruler 1 and rotary ruler 2 turn to suitable angle, makes slip chi 6 and ruler 1 fixing with rotary ruler 2 through trip bolt 7 then, gets final product the angle of picture different angles like this; When needs picture bowlder, can carry out the picture circle according to the chalk of ruler 1 and rotary ruler 2 ends; When needs are used set square, slip chi 6 and ruler 1 and rotary ruler 2 relative fixed are got final product, easy to use.
The utility model is simple in structure, and is reasonable in design, is convenient for carrying and uses, and integrates functions as one, and can alleviate teacher's burden, and can effectively improve efficiency of teaching.
