Mostly present number solely recreation is to fill in nine palace lattice of paper printing, if filling in mistake will alter again, time-consuming bothersome, one uses up, and change or repaint nine palace lattice again.

The utility model content

The purpose of this utility model is a kind of can the repeated use of design, carries, stores the only cribbage-board of magnetic number very easily.

The only cribbage-board of the utility model magnetic number comprises: supporting plate 1 and chess piece 3, and print on the supporting plate 1 or be carved with nine palace lattice 2 or post nine palace compartments 6, be provided with permanent magnet pieces 4 in every lattice.

Chess piece 3 comprises: ferromagnetic block 7, upper and lower two bottom surfaces of ferromagnetic block 7 are posted ply of paper, plastic layer or are scribbled enamelled coating 5, indicate the numeral of nine groups of 1-9 on ply of paper, plastic layer or the enamelled coating 5 respectively.

Chess piece 3 two sides indicate the same numbers of two kinds of colors.

Supporting plate 1 is monoblock or folded piece.

Supporting plate 1 can be made a box as base plate, has a little lattice box to place chess piece 3 in the box, or makees a little tub and place supporting plate 1 and chess piece 3.

The only cribbage-board of the utility model magnetic number is achieved in that and sets the solely corresponding chess piece 3 of topic numeral of number in the nine palace lattice 2 on supporting plate 1, color of the same race faces up, the chess piece 3 of filling a vacancy is placed on nine palace lattice, 2 outsides, if will insert numeral, just the digital supine chess piece 3 of another kind of color is inwardly filled, then chess piece 3 just is adsorbed on the permanent magnet pieces 4 of supporting plate 1; If do not put, so again and again till correctly filling up nine palace lattice 2 to taking off again.

The advantage of the only cribbage-board of the utility model magnetic number is: ferromagnetic block can be adsorbed on the supporting plate like a cork according to magnetic principles, use repeatedly, no matter traverse, place vertically and can not fall down or move, not only a people can fill, also can many people together weigh filling, also can hang over to demonstrate on the wall and see that to the student this plate structure is simple, carry, store very convenient by teacher, because chess piece is inhaled onboard, be not easy to lose, if the mistake of filling out, it is also very convenient to shift one's position.
