Abstract
The utility model discloses a nine-bead abacus, comprising a frame (1), a barrier strip (2) in the frame (1), and nine abacus beads (3) strung on the barrier strip (2), wherein the abacus beads (3) include a middle abacus bead (4), upper abacus beads (5) and lower abacus beads (6); the middle abacus bead (4) is strung on the barrier strip (2); four upper abacus beads (5) and four lower abacus beads (6) are positioned above and below the middle abacus bead (4) respectively; and the middle abacus bead (4), the upper abacus beads (5) and the lower abacus beads (6) are different from each other in color. By adopting the abacus beads different from each other in color, the abacus is vivid to count, simple and easy to learn, suitable for the cognition rule of infants and lower grade students, and convenient and intuitional to add, subtract and count so as to improve teaching and arithmetic learning, develop intelligence of students and culture actual operational ability of students; meanwhile, the nine-bead abacus has the advantages of simple structure and good operation convenience, and can be taken as teaching aid, learning tool and toy to spread and use.
Description
Technical field
The utility model relates to a kind of stationery, concrete ground say so a kind ofly be used to calculate, the Abacus of nine-bead on one shaft of teaching and intelligence development.
Background technology
Existing abacus generally is divided into up and down two lattice, and last lattice have one or two bead, and next have four or five beads.Each bead of last lattice is represented natural number 5, and each bead of following lattice is represented natural number 1.Can carry out the addition subtraction multiplication and division computing through bead location status of lattice and following lattice on abacus.For student who begins to learn arithmetic, counting or children, existing abacus is difficult to grasp, and obscures easily, so utilize existing abacus teaching not reach clear, understandable effect.Owing to the quantity odevity of middle-grade of abacus is indefinite, might cause children just to form stravismus and cause harmful effect in addition at aspects such as endeavouring exploitation or left and right sides brain balance from little.
Summary of the invention
The purpose of the utility model is the defective to prior art, a kind of distinctness that counts is provided, meets the Abacus of nine-bead on one shaft of child and students of the junior years' cognitive law.
The purpose of the utility model solves through following technical scheme:
A kind of Abacus of nine-bead on one shaft; It comprises framework and the shelves bar and 9 beads of string on the shelves bar that are located in the framework; Described bead comprises middle bead, goes up bead and following bead; In bead be installed on grade bar, the above and below of middle bead is coated with four respectively and goes up beads and four following beads, said in bead, to go up bead neither identical with the color of following bead.
The quantity of said shelves bar is 7-15.
The quantity of said shelves bar is odd number.
The quantity of said shelves bar is 11.
The bottom of said framework is provided with base plate.
The utility model is compared prior art has following advantage:
The utility model adopts the bead that varies in color respectively according to the difference of bead present position; Make that this abacus numeration is distinct, easy to learn; Meet child and students of the junior years' cognitive law; Can carry out plus and minus calculation, counting easily and intuitively, the study that helps improving teaching, arithmetic, and can develop student's intelligence and the actual operational capacity of cultivating the student.
The shelves bar quantity of the utility model adopts odd number, in use can not cause child strabismus, keeps left and right sides brain balanced growth.
The utility model is provided with base plate in the bottom of Abacus frame, makes the abacus one-piece construction stable, not fragile.
The utility model is simple in structure, easy to operate, suits to promote the use of as teaching aid, schooling apparatus and toy.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Wherein: 1-framework; 2-shelves bar; 3-bead; 4-middle bead; 5-upward beads; 6-following bead; 7-base plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: a kind of Abacus of nine-bead on one shaft, it comprises framework 1, moulding 2 and bead 3,7-15 shelves bar 2 is located in the framework 1, is serially connected with 9 beads 3 on each grade bar 2.This bead 3 comprises middle bead 4, goes up bead 5 and following bead 6, and middle bead 4 is installed on grade bar 2, and the above and below of middle bead 4 is coated with four respectively and goes up beads 5 and four following beads 6, and middle bead 4, to go up bead 5 neither identical with the color of following bead 6.For avoiding causing child strabismus, keep user's left and right sides brain balanced growth, the quantity of shelves bar 2 is set at odd number, and preferably adopts 11 shelves bars 2; For strengthening the structural strength of abacus, be provided with base plate 7 in addition in the bottom of framework 1.
The utility model adopts the bead that varies in color respectively according to the difference of bead present position, and bead 4 is red in preferred, and last bead 5 is yellow, and following bead 6 is a white; Make that this abacus numeration is distinct, easy to learn; Meet child and students of the junior years' cognitive law; Can carry out plus and minus calculation, counting easily and intuitively, the study that helps improving teaching, arithmetic, and can develop student's intelligence and the actual operational capacity of cultivating the student.And have simple in structure, easy to operate advantage, suit to promote the use of as teaching aid, schooling apparatus and toy.
The technology that the utility model does not relate to all can realize through prior art.
