Abstract
The utility model relates to a tool for teaching use, in particular to a multifunctional teaching aid with multiple purposes. The multifunctional teaching aid is characterized in that two compasses are connected together through a fixed shaft, and two compass fulcrum bars can freely rotate around the fixed shaft. A compass tip is fixed on the end portion of one compass fulcrum bar, and a chalk is fixed on one end portion of the other compass fulcrum bar. Two ends of a foldable ruler connect the two compass fulcrum bars through a fixed shaft, and the foldable ruler can be folded. One compass fulcrum bar is fixed with an angulometer which is provided with degree scales, and one end of the other compass fulcrum bar is provided with a blackboard eraser hairbrush, wherein the end of the other compass fulcrum bar is close to the foldable ruler. One end of a chalk box is connected with one compass fulcrum bar through a fixed shaft, and the chalk box can rotate around the fixed shaft and is provided with a chalk groove. The multifunctional teaching aid can achieve the functions of a straight ruler, a triangular rule, a compass, the angulometer, the chalk box and a blackboard eraser, and is small in size, convenient, practical, clean, tidy and beautiful.
Description
Technical field
The utility model relates to a kind of teaching tool using, is used for daily life, particularly a kind of Multifunctional teaching aid that serves many purposes.
Background technology
At present, math teacher is mapped at school and is often used ruler, set square, compasses, the such drawing tool of protractor.Therefore, teacher just must be ready to several instruments at school the time.In the time of mapping, normally used up a kind of instrument and got again another kind of instrument use afterwards, carried like this and used relatively more inconvenient; In addition, chalk holds chalk holder commonly used, so very occupation of land side; Simultaneously, present blackboard eraser adds a hairbrush by a plank and forms, and function ratio is more single.Like this, can place a lot of things on the little dais, both be inconvenient to impart knowledge to students, be unfavorable for again clean and tidy.
Summary of the invention
For above-mentioned problem, the utility model provides a kind of Multifunctional teaching aid.
The utility model is achieved through the following technical solutions: a kind of Multifunctional teaching aid is comprised of compasses pole, protractor, compasses point, folding rule, fixed axis, chalk, blackboard eraser hairbrush, chalk holder.It is characterized in that: two compasses poles link together by fixed axis, and two compasses poles can rotate freely around fixed axis, and compasses point and chalk are fixed on the end of compasses pole, and the folding rule two ends couple together two compasses poles by fixed axis, and folding rule can fold; Be fixed with the protractor with scale on the compasses pole; End near folding rule above the compasses pole has the blackboard eraser hairbrush; Chalk holder one end is connected with compasses pole by fixed axis, and chalk holder can rotate around fixed axis, and the above has ledge for chalk on blackboard.
This Multifunctional teaching aid can draw circle with a compass, and can use as set square and ruler, can take measurement of an angle with protractor, can use as blackboard eraser, and subsidiary chalk holder can hold chalk.
The utility model several functions unification, have one-object-many-purposes, convenient and practical, volume is little, light, the neat and artistic and advantage that is easy to carry about with one.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.
Among Fig. 1,1 compasses pole A, 2 protractors, 3 compasses point, 4 folding rules, 5 fixed axis A, 6 chalks, 7 blackboard eraser hairbrush, 8 compasses pole B, 9 chalk holders, 10 fixed axis B, 11 fixed axis C.
The specific embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.Compasses pole A1 and compasses pole B8 link together by fixed axis C11, two compasses poles can rotate freely around fixed axis C11, compasses point 3 is fixed on the end of compasses pole A1, chalk 6 is fixed on the end of compasses pole B8, folding rule 4 two ends couple together compasses pole A1 and compasses pole B8 by fixed axis A5, folding rule can fold, difference along with the folding degree of folding rule, two compasses poles are also different around the stretching degree of fixed axis C11 rotation, just can draw at blackboard the circle of different-diameter, realize the calipers function of Multifunctional teaching aid; Be fixed with the protractor 2 with scale on the compasses pole 1, the size that can take measurement of an angle, thus realized the function of angle gauge of Multifunctional teaching aid; When folding rule 4 is stretching, two compasses poles 1,8 and folding rule 4 be the equilateral triangle state, can use as set square, above the compasses pole 1 scale be arranged in addition, can use as ruler, thereby realize the set square of Multifunctional teaching aid and the function of ruler measurement; Above the compasses pole 8 near ends of folding rules with blackboard eraser hairbrush 7, the letter written with chalk on can erasing blackboard, thus realized the blackboard eraser function of Multifunctional teaching aid; Chalk holder 9 one ends are connected connection by fixed axis B10 with compasses pole, chalk holder 9 can be around fixed axis 10 rotations, the above has ledge for chalk on blackboard, can hold chalk, when without chalk the time, in the groove on the chalk holder 9 cycle compasses poles 1, when using chalk, screw out in the groove of chalk holder 9 from the compasses pole 1, in ledge for chalk on blackboard, take out chalk, thereby realized the chalk holder function of Multifunctional teaching aid.
Claims (2)
1. Multifunctional teaching aid, it is characterized in that: compasses pole A(1) and compasses pole B(8) by fixed axis C(11) link together, compasses points (3) and chalk (6) are fixed on the end of compasses bar, and folding rule (4) two ends are by fixed axis A(5) two compasses bars are coupled together.
