Description
Technical field
The utility model relates to teaching aid, specifically, relates to a kind of abacus teaching device.
Background technology
Rechoning by the abacus is a part for mathematical education, and because it is more abstract, and this contact of living is less, thus saying rechoning by the abacus class hour, if not demonstration in person of teacher is difficult to make student to accept at short notice its teaching content.Along with deepening continuously of modernizing teaching, teacher adopts computer teaching more, although this mode of giving lessons can reduce teacher's working strength, but the true essence that allows student really accept rechoning by the abacus still exists shortcoming.But the abacus teaching device existing mostly at present is original teaching appliance, expand by abacus, hang on wall and demonstrate, this abacus teaching utensil is not portable, use is inconvenient, takes up space larger.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and a kind of abacus teaching device that portably uses conveniently, takes up space little is provided.
For addressing the above problem, the technical scheme that the utility model adopts is:
Abacus teaching device, comprises framework, is provided with some root posts in framework, the surface of every root post is provided with burr, and every root post is provided with seven beads, it is characterized in that: described framework is divided into three sections of left, center, right, hinged between adjacent segment, framework both ends are provided with supporting leg.
Improve as one:
Described supporting leg is provided with universal wheel.
As further improvement:
Left section of described framework is hinged in front with stage casing, stage casing and right section hinged overleaf.
As further improvement:
Described framework is also provided with the folding fixture of framework.
The folding fixture of described framework comprises straight plate and the side plate perpendicular to straight plate two ends, and described biside plate is for arranging in the same way
Owing to having adopted technique scheme, compared with prior art, the utility model, by framework being divided into three sections, has been realized target folding framework, like this can be easy to carry, and it is little to take up space, when use, need not find hanger, can demonstrate before being placed on blackboard, easy to use; The not used time, after can being folded, fix with the folding fixture of framework, be easy to carry about with one and deposit.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
