Abstract

The utility model relates to a multi-purpose abacus, which comprises an outline border surrounded by frames, shelf rods and calculating beads. The shelf rods are respectively provided with a moving positioning plate 4 and a walking beam 5 which can slide between top and bottom on the shelf rods, and one frame inserted with the shelf rods on the outline border is movably connected with the two frames adjacent to the outline border. The utility model not only can carry out four arithmetic operations of addition, subtraction, multiplication and division by applying various abacus rules, but also can be used for playing various board games by disassembling the beads to use as pieces. The utility model integrates teaching, calculation and recreation into integration, and achieves the purpose of teaching through lively activities and developing intelligence.

Description

The multi-usage abacus

The utility model relates to a kind of multi-usage abacus.

Usually, people use or in the market, can buy mostly be seven rechoning by the abacus dishes (also some people uses six rechoning by the abacus dishes), but the custom that different countries and regions form for a long time according to people, employed abacus form but is very different, as the ten-bead abacus of Russia's use, the five-bead abacus that Japan uses etc.Caused the abacus of various countries to have a style of one's own so, and each self-forming the world of a sealing, be unfavorable for mutual interchange, to learn from other's strong points to offset one's weaknesses.In addition, existing abacus inconvenience dismounting, function singleness (can only do to calculate and use) can't be expanded gamespace.Chinese patent literature disclosed " a kind of removable whole abacus " (notification number: 2044365), it is characterized in that: a, all arbitrary outer ends of lever hole communicate with this end abacus long margin frame outer side edges; B, one is convenient to be placed on the cover plate of abacus frame dismounting the end face of lever hole.

The purpose of this utility model provides calculates apparatus and chess game is the new multi-purpose abacus of one a kind of the collection.

The purpose of this utility model is to realize like this, it comprises housing 1 and lever 2 and bead 3 by frame figure one-tenth, its contribution to prior art is, on described lever 2, be equipped with respectively and can do movable positioning plate 4 and the portable beam 5 that slides up and down on lever, movable positioning plate 4 and portable beam 5 are to insert lever by the perforation on it, and in the above-mentioned housing, it is inserted with a wherein frame of lever, is to flexibly connect with two frames that face mutually of this housing.

The utility model is that to another improvements of prior art it also comprises a digital display board 6, and this digital display board is connected with the bottom of described housing, and indicates numeral in its position corresponding to each bead.

Good effect of the present utility model is that it has not only overcome existing abacus lever and the indissociable shortcoming of frame, and an end frame of abacus can freely be dismantled, and according to people's different needs, can arbitrarily open frame, regulate bead, carry out the addition subtraction multiplication and division arithmetic.In addition, bead can be removed, to carry out various chess game activities as chess piece.This multi-usage abacus collection teaching, calculating, amusement are one, have reached and have taught through lively activities, the purpose of tap intellectual resources.

Below in conjunction with accompanying drawing the utility model is described further,

Fig. 1 is a front view of the present utility model,

Fig. 2 is digital display board 6 synoptic diagram of the present utility model,

Fig. 3 is the upward view of Fig. 1.

As shown in Figure 1, multi-usage abacus described in the utility model is made of digital display board 6 (as shown in Figure 2) and abacus body.This abacus body comprises housing 1 and lever 2 and the bead 3 that is surrounded by frame, the lower frame of housing is an active border 7, the left and right frame of the two ends of this active border and housing flexibly connects by screw 8, bead be can regulate as required earlier during installation, and movable positioning plate 4 and portable beam 5 on lever, loaded onto.Again with active border 7 good and sound the getting final product of lower end,

Bead of the present utility model regulated at will as required becomes five pearls, six pearls, seven pearls or ten-bead abacus, movable positioning plate 4 is used to regulate the spacing of bead (when only setting five pearls, six pearls or seven rechoning by the abacus dishes for, can be with its drop-down position) ten-bead abacus can not use movable positioning plate.And movable fine strain of millet can insert between bead as required,

During as needs seven rechoning by the abacus dishes, open active border 7, with bead, movable positioning plate 4 and portable beam 5, appearance according to seven rechoning by the abacus dishes begins assembling from top to bottom, on five levers 2, load onto earlier two beads 3 respectively, portable beam 5 is enclosed within on five levers 2 again, load onto five beads respectively for again five levers 2, put movable positioning plate 4, regulate bead and bead, and portable beam and movable positioning plate between mutual edge distance mutually, again five levers 2 are inserted respectively in five corresponding with it on the active border 7 circular holes, promptly be mounted to seven rechoning by the abacus dishes commonly used; Other abacuses are according to individual's different needs, and arbitrarily installation gets final product.

The utility model is that to another improvements of prior art it also comprises a digital display board 6, and this digital display board is fixedlyed connected with the bottom of abacus housing 1, and indicates numeral corresponding to the position of each bead.Above-mentioned digital display board 6 can snap in the bottom of abacus housing by the draw-in groove that is located at outer frame bottom, indicate ten thousand, thousand, hundred, ten on the digital display board 6 from left to right, the numeral of individual position, and can be provided with gridiron pattern as required, when stirring bead, from abacus, can be clear that the digital reading of dialling.Directly dial pearl, just can find out reading from digital display board 6.
