Abstract

The utility model relates to a multifunctional numerical-change quick-read abacus, belonging to the field of abacus. The utility model develops a multifunctional numerical-change quick-read abacus with the advantages of high efficiency, convenient use and easy learning which is a novel abacus at present. A method of one-to-one correspondence is adopted between the visualization of abacus reading and the visualization of the thinking of children. The numeral represented by an abacus bead is displayed on the bead rod of the abacus when the abacus bead is shifted. After a formula is calculated, the metering numerical bit of unit, ten, hundred, thousand, ten thousand, etc. labeled on the vernier clamp corresponding to the numeral displayed on each bead rod is the final numeral need to be calculated. The utility model can solve the problems that the beginners wrongly read the numerical bit and wrongly calculate the abacus beads.

Description

Multifunction numerical-change quick-read abacus

The utility model belongs to the abacus field.

Old-fashioned abacus has prolonged history with several thousand in our country, it has come very big convenience for daily contacts, metering generation of people, but the beginner is still existed the shortcoming of grasping not too easily, in order to develop this outstanding legacy of the Chinese nation, the purpose of this utility model is, developed a kind of at present the most novel high efficiency, intuitively, enlightenment, easy multi-functional several speed changes understandable, that easily learn read abacus.

Taked following technical scheme to realize in order to realize above-mentioned the utility model: to utilize the intuitive of children thought to adopt method one to one, promptly pull out a bead, the numeral that will demonstrate this pearl representative on the pearl bar of abacus is shown its size, and on the abacus intermediate transverse girder, be equipped with indicate above the vernier card, ten, hundred, thousand, ten thousand ... the metering figure place.Calculated to make and begun to learn the result calculated that rechoning by the abacus person reads rapidly, for this abacus of realization that guarantees above-mentioned functions has adopted following structure: circle is processed with two guide grooves that can make pearl bar Rotate 180 ° in the pearl on abacus, on the pearl bar, be processed with boss and guide groove matches, on the edge of last pearl, also be processed with spacing groove, on Abacus frame, gag lever post is installed and limited impression matches, like this on stirring during pearl under the effect of power, the pearl bar can rotate a certain angle automatically.When will go up pearl when pulling out top dead centre the pearl bar forward the one side that indicates 0,1,2,3,4,5 numerals successively to, when going up pearl when pulling out bottom dead center position, pearl bar Rotate 180 ° forwards the one side that indicates 6,7,8,9,10 numerals successively to, pulling out what beads all has a corresponding numeral to show on the pearl bar, this numeral changes along with the upper and lower motion of last pearl, simultaneously also with moving up and down and different of pearl down, shown numeral is exactly that you want the result calculated numeral on abacus.

The useful novel following several characteristics that has of this reality: 1., the schooling apparatus of optimum pupil rechoning by the abacus, can also organically dress up one to this abacus and multi stationery set, make things convenient for the pupil.2., this abacus reads intuitively, calculate easy, made things convenient for religion person as long as the teacher tells the student relevant rechoning by the abacus knowledge by teaching method, the student does not reintroduce the problem of " why ", teaching efficiency also is bound to improve greatly.3., thoroughly solved and begun to learn rechoning by the abacus person and misread the disadvantage that pearl is miscounted in figure place and calculating, after new-type abacus had calculated, its can demonstrate the result automatically on the pearl bar.4., certain interest is arranged, just can find out zero position, every group of bead as long as the student stirs bead, will demonstrate different numerals on the pearl bar, not only can proofread when dialling pearl like this to mistake, certain interest is also arranged, make the student like new partner more.

Figure of description is an embodiment synoptic diagram of the present utility model, and Fig. 1 is the plan front view of this abacus, and Fig. 2 is the A-A sectional view of Fig. 1, Fig. 3 goes up pearl parts front view, Fig. 4 is the B-B cross section view of Fig. 3, the front view of Fig. 5 pearl bar parts, and Fig. 6 is the rear view of pearl bar parts.

Below in conjunction with the embodiment accompanying drawing the technical solution of the utility model further is illustrated:

On the basis of existing abacus, on the interior circle of last pearl ［ 3 ］, be processed with two guide grooves ［ 12 ］ that can make pearl bar ［ 13 ］ Rotate 180 °, be added with two boss ［ 15 ］ on each pearl bar ［ 13 ］, the outer rim place of pearl is processed with stopper slot ［ 2 ］ and on the Abacus frame gag lever post ［ 1 ］ is installed simultaneously on each, when last pearl when doing upper and lower motion, can drive the pearl bar and do 180 ° of rotations.On pearl bar ［ 13 ］, indicate 0,1,2,3,4,5 numeral, another side indicates 6,7,8,9,10 numeral, when going up pearl ［ 3 ］ when pushing top dead center position, in perform 6,7,8,9,10 numeral of pearl bar, be marked with 0,1,2,3,4,5 numeral when pushing bottom dead center position at the pearl bar when going up pearl, no matter stir what beads and can only show a numeral on the pearl bar, this numeral changes along with the upper and lower motion of last pearl.On the crossbeam ［ 8 ］ of abacus, also be equipped with indicate above the vernier card ［ 11 ］, ten, hundred, thousand, ten thousand ... the metering figure place, can make the beginner read institute's result calculated rapidly after the calculating.

An embodiment of the present utility model can organically be combined into one abacus with multi stationery set, the pupil bought this writing case just equal to have one easy computational tool, when making mathematical problem, can directly check with abacus, so both strengthen thinking ability, also improved the rechoning by the abacus level.

Claims (2)

1, to read abacus be by framework to a kind of multi-functional several speed changes, crossbeam, last pearl, the pearl bar, bead is formed, it is characterized in that being processed with on the interior circle of last pearl two guide grooves that can make pearl bar Rotate 180 °, the interior round guide groove that is processed with two boss and last pearl on each pearl bar matches, and is processed with the gag lever post of installing on limited impression and the Abacus frame on the outer rim of pearl and matches on each.

2, multi-functional several speed changes as claimed in claim 1 are read its feature of abacus the vernier card are installed on the abacus crossbeam, are marked with at the vernier card, ten, hundred, thousand, ten thousand ... the metering figure place.
