Abstract
The utility model relates to an automatic lighting abacus. One side of an abacus frame is matched with a power supply chamber; batteries are matched in the power supply chamber; each iron gear of the abacus is accessed into the negative electrode of a power supply after connected with a connecting wire; a sheet metal digit display board on the cross beam of the abacus is accessed into the positive electrode of the power supply; the middle part of a bead is provided with a light emitting lamp bead; the positive electrode of the lamp bead is accessed onto ferrules on both sides of the bead, and the negative electrode is contacted and conducted with the iron gear through the inside of the bead, so the bead which is pushed upward lights during calculation, the bead which is pushed downward automatically loses light; operators can clearly see the operational situation of beads on the abacus, wrong push can be prevented, the work efficiency can be improved, and particularly the automatic lighting abacus has much benefit in abacus teaching.
Description
The utility model relates to the improvement of the calculation element in a kind of instrument, specifically abacus is improved.
The abacus that existing market is sold and people generally use, as the patent No. is 86208154,86300757, when this device of utilization calculates, bead on dialling and the bead of backing off do not have obvious hue distinguishes, do not reach open-and-shut effect, make accounting formation work carelessness easily, produce many groups or few dialling, rate of reading is also slower, particularly in the abacus teaching, and bathomorphic classmate or be sitting in the classmate far away and can not be clear that on the teaching-aid abacus each dials the pearl situation from the dais.
The purpose of this utility model is to mix lamp pearl or light emitting diode in the bead of existing abacus, is furnished with power supply simultaneously, makes the bead on dialling luminous, and the bead loss of gloss of backing off comes into plain view application abacus reckoner and sees the numerical value situation of calculating on the abacus clearly.
The utility model is to realize like this, it comprises the framework on the abacus, the iron shelves, bead, the sheet metal figure place display board that covers on crossbeam and the crossbeam, described new type auto luminous abacus, side at Abacus frame is furnished with devices such as power supply room and accessory switch, one end of each root iron shelves of abacus inserts the negative pole of switch after by lead and its binding, the width of figure place display board extends the bag crossbeam downwards on both sides, every iron shelves place, but do not contact with the iron shelves, the figure place display board is being positioned at power supply room one end connects back access switch with lead positive pole, be furnished with light emitting diode or lamp pearl in the intermediate of each bead upper half plane, the two sides of bead is provided with becket, the negative pole of light emitting diode contacts conducting by in the bead body with the iron shelves, the positive pole of light emitting diode inserts the becket on bead two sides, the following demifacet neither one aperture of each bead, pass this aperture with a tinsel, its two ends wiry are fixed on up and down on two frameworks, make the light emitting diode of bead upper half plane not change the abacus back side over to, and can slippage on the iron shelves.
Described new type auto luminous abacus is provided with branch position lamp on crossbeam, divide the positive pole of position lamp and figure place display board to connect, and negative pole is connected with the iron shelves.
Described new type auto luminous abacus is furnished with battery in power supply room, the power supply room outside is furnished with switch, the positive and negative extreme spring of the positive and negative electrode of switch and power supply room is with the lead conducting that links to each other, the back side of power supply room is provided with cover plate, do not have recessed the button on the cover plate, be convenient to cover plate and take off from the back side of power supply room and be used for loading and unloading battery.
During work, open switch, branch position lamp on the beam is all luminous, abacus can operate as normal, when stirring first bead by beam, this moment, the positive pole of the luminotron on this bead will contact the conducting shinny work of switching on because of figure place display board sheet metal (positive pole) set on the becket on the bead (positive pole) and the beam, when stirring second bead, the becket of second bead front contacts the conducting energising and makes that second bead is luminous with the becket of first bead back, the rest may be inferred for all the other, when when setting aside pearl, because the becket of the becket of the front of the bead under dialling and bead back, front or the figure place display board sheet metal on the beam break away from outage and extinguish automatically.When not working switch cuts out, branch position lamp set on the beam extinguishes automatically.
Advantage of the present utility model is owing to make that the work bead is luminous, the bead of not working is unglazed, be applied in the accountancy, not only can improve accountancy person's rate of reading, reach open-and-shut effect, and accountancy carelessness is produced many groups or few phenomenon of dialling unique prevention effect is arranged, can increase work efficiency significantly.Particularly be used in the abacus teaching, can help the classmate of hypometropia or be sitting in to see fully aware ofly that on the teaching-aid abacus each stirs the situation of bead apart from dais classmate far away, and can excite classmates to learn the interest of rechoning by the abacus, very helpful to the raising of quality of instruction.
Describe the utility model in detail below in conjunction with accompanying drawing
