Abstract

The utility model discloses a novel abacus, by last lower frame, well roof beam, calculating pearl, clear shelves ware, leveler, bottom plate group become, the leading features is: when the abacus is leveled, the eccentric shaft is adjusted, the balance plate connected with the eccentric shaft makes the spring steel sheet generate deformation to drive the suction pad arranged on the supporting plate to lift or fall, so that the abacus is stably contacted with the supporting surface, the upper and lower frames and the middle beam are both provided with position marks, the position marks can be marked independently, or can be marked on the upper and lower frames and the middle beam in any combination or simultaneously, the cross section of the clearing rod is right-angled, square or prismatic, the clearing enables the abacus beads to be in place once, and the abacus is suitable for being used for financial staff and abacus contestants, and can also be used for counting children.

Description

Abacus

The utility model relates to a kind of computational tool, particularly relates to a kind of novel abacus.

The leveller of existing abacus is regulated dumbly, is in 90209929.9 the utility model application case as number of patent application, outside the end frame of abacus leveling board is installed, during leveling, must take up abacus changes an angle to the leveling board on both sides, put down again, with the desktop levelling, the leveling inconvenience; Have a target abacus, it is only to be located on the central sill function singleness that its mark indicates, reading is not directly perceived, is not convenient for the personnel that are engaged in all kinds of work and uses, and clear lever xsect is a garden shape, exist shelves back bead resilience clearly, the disadvantage that the once clear shelves of bead are put in place.

The purpose of this utility model is, provides a kind of leveling convenient to society, is equipped with the position mark on upper and lower frame and central sill, and clearing device can the once clear grade novel abacus that puts in place.

The utility model can be realized with following mode:

Leveller is by spring steel plate, excentric shaft, balance plate, supporting plate is formed, excentric shaft is arranged on left and right side frame the inner, release handle is connected with excentric shaft and stretches out outside the left and right side frame, balance plate places on the excentric shaft, the garden arc that balance plate lower limb middle part concaves contacts with the excentric shaft outer rim, spring steel plate places the balance plate upper edge, its top props up left and right sides upper side frame, the balance plate bottom places on the supporting plate, in supporting plate and relative position, balance plate bottom, 4 rubber blankets are set, on upper and lower side frame and central sill, be provided with by the unit of arabic numeral or numeration decimally and pick up printed words such as 1,000,110,000, or the position mark of point ". " sign, the position mark can be by every kind of symbol, printed words or point ". " indicate separately, also can be marked on upper side frame simultaneously by two kinds of combination in any wherein or three kinds, on lower frame and the central sill; The xsect of the upper and lower clear bar of clearing device is square, square or prismatic.

Advantage of the present utility model:

1, the position mark that arabic numeral indicate is set and simplifies the process that all types of match contestants recognize shelves, look into the position, improve arithmetic speed and accuracy rate, the position mark that indicates with point ". " can be used for children and sees that number looks into positions, enhancing is to the understanding of the position of counting the number of words, decimally the position mark that 1,000,110,000 printed words such as grade indicate picks up in Ji Shuo unit, uses for the professional, and the people is coiled conveniently, result of calculation is directly read, and need not to look into the position;

2, the visual use field condition of leveller leveling abacus at any time, leveling is convenient, abacus displacement in having avoided using, the disadvantage of bead shakiness.

3, adopt the clear lever of square, square or double-wedge section, can put in place by an once clear shelves bead, do not make the bead resilience;

4, base plate is a board plug type, avoids the abacus distortion of making moist;

Fig. 2 is Fig. 1 left view;

Fig. 3 is the leveller structural representation;

Fig. 4 is the base plate scheme of installation;

Embodiment:

As shown in drawings, in the left and right side frame 1 of abacus and 5 inner end, excentric shaft 13 is set, release handle 7 one ends are loaded on the excentric shaft 13, the other end stretches out outside left and right side frame 1 and 5, and balance plate 14 places excentric shaft 13 upper ends, and the garden arc that its lower limb middle part concaves contacts with excentric shaft 13 outer rims, spring steel plate 11 places balance plate 14 upper edge, its top props up abacus left and right side frame 1 and 5 upper ends, and balance plate 14 bottoms place on the supporting plate 16, in supporting plate 16 and balance plate 14 relative positions 4 rubber blankets 12 is set, need only rotate the outer release handle 7 of abacus left and right side frame during leveling respectively, excentric shaft 13 rotates balance plate 14, supporting plate 16, rubber blanket 12 rises thereupon or falls, reach the purpose of leveling abacus, when for example the cashier used, through adjusting, rubber blanket 12 can be inhaled on workplace, make abacus stable, bead 10 is not disorderly; The player participates in competition when using, and rubber blanket 12 upwards is transferred to the room, and the abacus bottom surface contacts non-resistance with examination paper, the efficient height; On top doing the position mark with arabic numeral on the frame 3 indicates, deserve to be called the position mark, doing the position mark with point ". " on the central sill 6 indicates, claim the meta mark, the unit that decimally counts on the lower frame 9, pick up, hundred, thousand, ten thousand printed words such as grade are done the position mark and are indicated, claim the next mark, upper mark is used for the contestant, in full 93876.54, the player is seeing when several, identification is 5 figure places, according to the upper mark among Fig. 1, need not look into the position, can be directly into dish, draw answer: 9,847,563.25, when writing, need not look into the position yet, the step-by-step mark can directly write out model answer, the meta mark is used for children and directly sees number, look into the position, help children to understand the variation of numerical digit, the next mark is set up for the professional, coils according to the rapid people of different numerical digits in calculating, result of calculation is embodied directly in the position and puts on, directly read, for example, 1.46 yuan of the every chis of cotton are sold in certain shop, certain purchase of customer 3 chis, 4.38 yuan of the amount of money adopt and calculate prelocalization, calculate back answer in full and all put on the next, come into plain view, more than be position mark by every kind of symbol, printed words or point ". " are indicated in the embodiment on upper and lower side frame 3.9 and the central sill 6 separately, also can be indicated in simultaneously on upper side frame 3 lower frames 9 and the central sill 6 by wherein two kinds of combination in any or three kinds, the supernatant lever 4 of clearing device and following clear lever 8 are the steel wire making at right angle by xsect, make bead 10 one-time-reach-places in the time of clear grade, do not produce resilience, on, it is square that following

clear lever

4 and 8 also can adopt xsect or the steel wire of prismatic is made, base plate 16 is to insert back cover along the groove of upper side frame 3 and lower frame 9 bottoms, can conveniently take off, the top and bottom surface of abacus ventilates consistent, not yielding.
