Abstract
The omnipotent counter of nine pearls relates to a kind of teaching and computational tool.The utility model is provided with lever and bead in a framework, it is characterized in that: fix two vertical shafts at two ends, frame roof upper surface left and right, vertical shaft is equipped with runner respectively, runner is set with a closed unit of account display band, the outside surface of unit of account display band mark in the position with every row bead consistency from top to bottom the word commonly using unit of quantity.The utility model has the advantages that: more directly perceived when carry exercise and the application varying number unit of children for learning abacus, set up abacus carry sooner, more accurately and associate with the thinking of unit of quantity.Meanwhile, more convenience is brought to adult and any beginner.This nine pearls omnipotent calculator structure is simple, is easy to operation, low cost of manufacture, easy to utilize.
Description
Technical field
The utility model relates to a kind of teaching and computational tool.
Background technology
Current, although enter computer age, but easy to learn, visual pattern, pearl number due to Chinese tradition abacus combine and right-hand man by the feature of computing, for promotion children left and right brain balanced growth, effectively cultivate the notice of children, memory, observation, the power of imagination and thinking and all benefit.Tradition abacus does not only step down from the stage of history, and also becoming a kind of good method of tempering mental arithmetic, memory capability, is the good tool of children's development intelligence.Meanwhile, be also the most Simple tool of adult's addition subtraction multiplication and division arithmetic.Based on above reason, the present inventor patent " double-colored nine pearl general-purpose abacus " (patent No.: 200620030134.9) and " the nine pearl general-purpose abacus of anti-scattered pearl " (patent No.: 200520031907.0) new improvement is carried out on basis, the potential advantages playing further Abacus of nine-bead on one shaft are very necessary.
Summary of the invention
The purpose of this utility model is further modified node method on above-mentioned patent basis, improves effective utilization.
The technical solution of the utility model is: in a framework, be provided with lever and bead, it is characterized in that: fix two vertical shafts at two ends, frame roof upper surface left and right, vertical shaft is equipped with runner respectively, runner is set with a closed unit of account display band, the outside surface of unit of account display band mark in the position with every row bead consistency from top to bottom the word commonly using unit of quantity.
The beneficial effects of the utility model: the utility model is more directly perceived when the carry exercise of children for learning abacus and application varying number unit, sets up abacus carry sooner, more accurately and associates with the thinking of unit of quantity.Meanwhile, more convenience is brought to adult and any beginner.This nine pearls omnipotent calculator structure is simple, is easy to operation, low cost of manufacture, easy to utilize.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, be provided with lever and bead 2 in a framework 1, form basic Abacus of nine-bead on one shaft structure, its method of operating is consistent with traditional abacus.
Fix two vertical shafts 3 at two ends, framework 1 dome top surface left and right, vertical shaft 3 is equipped with runner 4 respectively, the unit of account display band 5 that on runner 4, suit one is closed.Runner 4 is made with plastic material, and the unit of account display fibrous material of band 5 with elasticated is made, and making can ease rotation, can not come off easily again.Meanwhile, the unit of account display band 5 marking not commensurate can also be changed as required at any time.
The outside surface of unit of account display band 5 mark in the position with every row bead 2 consistency from top to bottom the word 6 commonly using unit of quantity.These conventional units of quantity are: " hundred, ten, unit, angle, point "; " ten thousand, thousand, hundred, ten, individual "; " kilogram, hectogram, ten gram, grams "; " km, hundred, rice, decimetre, centimetre " etc. unit of quantity's grade like this, be printed on unit of account display band 5.
During use, as long as stir runner 4, following bead 2 is aimed at by corresponding unit of quantity on unit of account display band 5, the result of different measurement unit can be shown very intuitively.
