Description
Technical field
The utility model belongs to teaching aid field more particularly to abacus teaching teaching aid.
Background technique
Rechoning by the abacus is a kind of more traditional calculation method in the way of the one kind calculated by abacus is counted and China,
Rechoning by the abacus at present also offers corresponding course in teaching.Rechoning by the abacus is mainly that abacus and exclusive algorithm pithy formula is used to carry out in fact
It calculates, so instructor can use the abacus model of amplification to carry out demonstration explanation for student in curricula.Existing calculation
Disk must will be holded up in teaching demonstration and is shown, can the position of bead can move under the effect of gravity, so the prior art
In devise a variety of abacus teaching aids to solve the above problems, but all can not get rid of using amplification abacus structure this ask
Topic, so that teaching process is inconvenient.
Utility model content
The purpose of the utility model is to provide a kind of abacus teaching teaching aid, the utility model is calculated using drawing plane substitution
Dish structure, while the demonstration of abacus teaching is carried out using semi-circular arc block as bead, structure is simple, compact, uses
It is very convenient.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:
A kind of abacus teaching teaching aid, the teaching aid include cabinet and bead, and the outer wall of the same side wall of cabinet is equipped with
Outline border coating, crossbeam coating and the lever coating of abacus, be divided on the cabinet above crossbeam coating between outline border coating,
The decorative pearl on top of an official cap fate of lower setting and the decorative pearl on top of an official cap calculate area, are divided on the cabinet between crossbeam coating lower section and outline border coating and setting above and below
The bottom pearl fate set and bottom pearl calculate area, and correspondence is installed with iron plate on the inner wall of wall box where lever coating；The calculation
Pearl includes semi-circular arc block, and the intrados midpoint of bead is installed with the first magnetite item.
Preferably, the iron plate corresponds to lever coating and is arranged and is located at decorative pearl on top of an official cap fate and bottom pearl fate；Top, bottom pearl meter
It calculates wall box outer wall at the lever coating in area and is equipped with several grooves, groove and the first magnetite item cooperate.
Preferably, it is correspondingly provided with the second magnetite item on the inner wall of side wall where the groove, the S of the second magnetite item is to magnetic pole
It is arranged towards groove, the S of the first magnetite item is connect to magnetic pole with semi-circular arc block.
Preferably, two articulated stands are correspondingly provided with where the groove on the inner wall of side wall, shaft passes through the second magnetite item
It is connect afterwards with two articulated stands, the N of the second magnetite item is hinged to magnetic pole and connecting rod one end, below the connecting rod other end and articulated stand
Pull rod one end it is hinged, the pull rod other end pass through side wall after be exposed to the external world.
Preferably, pull rod is exposed to extraneous end equipped with setting stick, and the pull rod body of rod between setting stick and connecting rod is equipped with limit
Position block, limited block are arranged close to the hinged place of connecting rod and pull rod.
Preferably, the connecting rod and pull rod are under plumbness, and limited block, which reclines, contacts connecting rod.
The utility model use process is as follows:
Cabinet is set cated side to show towards student, and in the initial state, several beads are respectively placed in
At lever coating in top, bottom pearl fate, it is however generally that, two decorative pearls on top of an official cap and five bottom pearls are placed on every lever coating, point
It does not use the decorative pearl on top of an official cap as and bead that bottom pearl uses is using suction-operated of the first magnetite item to iron plate, be adsorbed on the corresponding of lever coating
At position on cabinet exterior.
When carrying out calculating demonstration, the adsorption capacity of the first magnetite item and iron plate can be overcome, corresponding bead is placed on top, bottom
Pearl calculates in the response groove in area on lever coating.Bead is not only by the limit of groove, while the first magnetite item and second
There is a natural attraction between the sexes for magnetite item, also bead is effectively prevent to fall off from cabinet.
When needing the bead in mobile computing area, pull rod is pulled using setting stick, so that pull rod is mobile towards cabinet outside,
Pull rod drives the second magnetite item to rotate around articulated stand by connecting rod, so that the N of the second magnetite item is moved down to magnetic pole, S is to magnetic pole
It moves up, so that the adsorption capacity of the first magnetite item and the second magnetite item reduces, instructor can easily take out from groove and calculate
Pearl prevents instructor to overcome the adsorption capacity of two magnetite items and overexert and cause bead to slip out of the hand to throw away.After taking out bead, to
Pushing drawing rod in cabinet, pull rod and connecting rod will receive when vertical the effect of limited block to can not pushing drawing rod, under this state, the
Two magnetite items are in horizontality and its S is arranged to magnetic pole towards corresponding groove.Certainly, the spacing of adjacent two second magnetic stripe is answered
When meet its rotation the needs of.
The utility model compared with prior art, has the advantages that the utility model substitutes abacus using drawing plane
Structure, while the demonstration of abacus teaching is carried out using semi-circular arc block as bead, structure is simple, compact, uses ten
It is convenient to divide.
