Abstract
The utility model relates to a single bead type abacus, comprising an abacus frame, abacus bars and abacus beads, wherein, each abacus bar strings one abacus bead, the abacus bead forms a five prismatic shape, and five prismatic surfaces all display numbers. When the abacus bead is at the lower part, the abacus bead represents 0, 1, 2, 3, 4. When the number reaches 5, the abacus bead rises up and represents 5, 6, 7, 8, 9. When the number reaches ten, another abacus bead is increased. The single bead of the utility model can represent ten Arabic numerals. The utility model has the advantages of beads saving, beams saving, simple structure, small size, no fault, convenient carrying, easy fabrication, low cost, no need of energy sources, etc. In the process of calculation, moving beads are replaced by whirling beads. Abacus operation, mental arithmetic and manual computation are combined organically. The utility model is an ideal tool to develop children' intelligence and enhance adults' wisdom, and users' brains can get exercise.
Description
The utility model relates to a kind of single bead number type abacus.
Existing rhombus five-bead abacus (patent No. 86208154.86300757) is the same with traditional seven rechoning by the abacus dishes crossbeam, and with pearl algebraically, bead is many, complex structure, the user must grasp pithy formula, begins to learn difficulty, operation fortune pearl trouble, multiplication and division computing location is difficult, and the abacus volume is big, and inconvenience is carried.
The purpose of this utility model is to produce a kind of single bead number type abacus that does not have crossbeam, and it had both kept Chinese abacus does not need the energy, hand brain and usefulness increase the intelligence function, it is small and exquisite nimble to have electronic calculator again, digitally shows advantage easy to carry.
The utility model is achieved like this, it is made up of calculation frame, calculation shelves, bead, on the calculation frame, be embedded with some side by side and calculate shelves, every abacus string has a bead, and bead is five prismatics, and each faceted pebble is represented with five arabic numeral of 0-4, bead under represent 0,1,2,3,4, full five rise, expression 5,6,7,8,9, and full ten advance one.Iron chains embedding magnetic material above the bead, in order to inhaling on the inboard iron plate of abacus upper ledge, lower surface has a wedge, is meshed with the skewed slot of abacus lower frame inboard, in order to liquidation.There is a hole of bead centre, and the hole of bead is five prismatics with calculating shelves, is convenient to decide pearl, make literal can deflection, reading is directly perceived.
The utility model is to count Dai Zhu, and number shows that single pearl can be represented 10 arabic numeral, and full five rise, and full ten advance one.Economize pearl, economize beam, simplify the structure greatly, changing group pearl in calculating process is ball, and rechoning by the abacus, written calculation, mental arithmetic three organically combine, and user's brain obtains taking exercise, and reaches to increase the intelligence effect, has overcome the drawback that the hyundai electronics counter is not required mental skill.
Below in conjunction with accompanying drawing the utility model and operational method thereof are further described below.
Accompanying drawing 1 is a synoptic diagram of the present utility model.
Accompanying drawing 2 is the synoptic diagram of bead.
In the drawings: 1, calculate frame; 2, calculate shelves; 3, bead; 4, wedge; 5, skewed slot; 6, hinge; 7, magnetic material; 8, the hole of bead.
As shown in Figure 1 and Figure 2, the utility model is made up of calculation frame 1, calculation shelves 2, bead 3, on calculation frame 1, be embedded with some side by side and calculate shelves 2, every abacus string has a bead 3, and bead is five prismatics, and five faceted pebbles are represented by five arabic numeral of 0-4 respectively, bead is representing 0,1,2,3,4 respectively down, full five rise, expression 5,6,7,8,9, and full ten advance one.Bead upper surface iron chains embedding magnetic material 7, in order to inhaling in abacus upper ledge inboard, lower surface has a wedge 4, intermesh with the skewed slot 5 of abacus lower frame inboard, in order to liquidation, the centre is the hole of bead 8, and the hole of bead is five prismatics with the calculation shelves, be convenient to decide pearl, make literal can deflection, reading is directly perceived, for easy to carry, in the middle of calculating frame, can adorn one pair of hinge 6, carry in order to folding.
Only need rotate bead during the utility model computing, when doing signed magnitude arithmetic(al), it is good with summand or minuend cloth only to need, and then addend or subtrahend is directly calculated diligently, and dials the transhipment pearl from left to right, draws result of calculation; When doing the multiplication and division computing, multiplicand or dividend cloth the right, the multiplier or the divisor cloth left side are by the computing of traditional Chinese rechoning by the abacus method.In order to simplify the multiplication and division extracting operation, the utility model can double plate and usefulness, is about to the single bead number type abacus, two dishes are used in combination side by side, during multiplying, dish the right on the multiplicand cloth, the limit of facing left on the multiplier cloth, long-pending cloth lower wall the right, earlier use the multiplier units, multiply by multiplicand from left to right, with product to good position, multiply by multiplicand with tens again, and the like.When doing division or evolution, dividend cloth lower wall the right, the limit of facing left on the divisor cloth, the rechoning by the abacus division arithmetic is equally finished by the written calculation division in dish the right on merchant or the root cloth.
