Abstract

The utility model discloses a kind of child abacus, including outer framework, crossbeam, beading bar and abacus bead, the crossbeam is connected in the outer framework, it is parallel to each other between the beading bar, in the outer framework, the beading bar intersects with the beam vertical, and all string has multiple abacus beads on every beading bar, identical with the abacus bead shape on root beading bar, the abacus bead shape on different root beading bars is different；The cross sectional shape of the beading bar is square, and the abacus bead central hole is identical with the beading rod-shape, size is adapted.Abacus bead shape on the utility model difference root beading bar is different, convenient for children knows well various geometries, and cause that abacus numeration is distinct, easy to learn, novel appearance, meet child and primary grades children cognition rule, raising uses interest, is suitably promoted the use of as teaching aid, schooling apparatus and toy.

Description

A kind of child abacus

Technical field

The utility model is related to the abacus that a kind of suitable children use.

Background technology

At present, the abacus style of commercial type is various, but generally there are that unitary function, outward appearance are not novel enough, use model Enclose not extensive shortcoming.

Utility model content

The purpose of this utility model is to provide a kind of child abacus, and its novel appearance is vdiverse in function.

To achieve the above object, the utility model uses following technical scheme：

A kind of child abacus, including outer framework, crossbeam, beading bar and abacus bead, the crossbeam are connected to the outer framework Interior, parallel to each other between the beading bar, in the outer framework, the beading bar intersects with the beam vertical, every All string has multiple abacus beads on beading bar, abacus bead different root beading bars on identical with the abacus bead shape on root beading bar Shape is different；The cross sectional shape of the beading bar is square, the abacus bead central hole and the beading rod-shape Identical, size is adapted.

The beading bar has 13, and the face shape of facing of abacus bead is followed successively by circular, oval, pros on the beading bar Shape, parallelogram, rhombus, trapezoidal, zither shape, triangle, regular pentagon, regular hexagon, annular, sector, pentalpha.

Preferably, the abacus bead surface is provided with phosphor powder layer.

Further, it also includes calculator, and the calculator is connected to the outer framework right side.

After adopting the above technical scheme, the utility model has the following advantages that：

1st, the abacus bead shape on the utility model difference root beading bar is different, and convenient for children knows well various geometric forms Shape, and abacus distinct, easy to learn, the novel appearance of numeration is caused, meeting child and primary grades children cognition rule, raising makes With interest, suitably promoted the use of as teaching aid, schooling apparatus and toy；

2nd, the cross sectional shape of beading bar is square, can limit abacus bead and be spinned on beading bar, convenient use；

3rd, abacus bead surface is provided with phosphor powder layer, it is adaptable to dark place, while increasing interest；

4th, outer framework right side is connected with calculator, convenient and swift for verifying abacus result of calculation.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Reference numeral explanation:

Outer framework 1, crossbeam 2, beading bar 3, abacus bead 4, calculator 5.

Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model, is not used to limit the utility model.

With reference to Fig. 1, the utility model discloses a kind of child abacus, including outer framework 1, crossbeam 2, beading bar 3 and abacus Pearl 4, crossbeam 2 is connected in outer framework 1, parallel to each other between beading bar 3, and in outer framework 1, beading bar 3 is vertical with crossbeam 2 It is intersecting.

All string has multiple abacus beads 4 on every beading bar 3, different roots identical with the shape of abacus bead 4 on root beading bar 3 The shape of abacus bead 4 on beading bar 3 is different, and in the present embodiment, beading bar 3 has 13, and abacus bead 4 is being just on beading bar 3 Circle, ellipse, square, parallelogram, rhombus, trapezoidal, zither shape, triangle, regular pentagon, just are followed successively by depending on face shape Hexagon, annular, sector, pentalpha.

The cross sectional shape of beading bar 3 is square, and the central hole of abacus bead 4 is identical with the shape of beading bar 3, size is mutually fitted Match somebody with somebody, beading bar 3 can limit abacus bead 4 and be spinned on beading bar 3, convenient use；

The surface of abacus bead 4 is provided with phosphor powder layer, it is adaptable to dark place, while increasing interest.

Further, it also includes calculator 5, and calculator 5 is connected to the right side of outer framework 1, and knot is calculated for verifying abacus Really, it is convenient and swift.

The shape of abacus bead 4 on the utility model difference root beading bar 3 is different, and convenient for children knows well various geometric forms Shape, and abacus distinct, easy to learn, the novel appearance of numeration is caused, meeting child and primary grades children cognition rule, raising makes With interest, suitably promoted the use of as teaching aid, schooling apparatus and toy.

More than, only the utility model preferably specific embodiment, but protection domain of the present utility model is not limited to In this, any one skilled in the art in the technical scope that the utility model is disclosed, the change that can be readily occurred in Change or replace, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with power The protection domain that profit is required is defined.
