Abstract

The utility model relates to a novel three-dimensional magic block, which belongs to the field of the educational toy. Based on the pentomino, the three-dimensional magic block has an improved structure and comprises a Z-shaped three-dimensional sub-block and an L-shaped three-dimensional sub-block. In addition to the assembly of such geometric shapes as the cube and cuboid, the utility model can be used for creating the animal, building, daily necessity and other three-dimensional models. Moreover, each model can be formed in different ways and the assembly methods vary endlessly.

Description

The novel solid magic square

Technical field

The utility model relates to a kind of educational toy, is specifically related to a kind of novel solid magic square.

Background technology

Now, children's toy emerges in an endless stream, but can be used for study, and intelligence, interesting stronger toy are seldom.

Building blocks type toy, structure are too simple especially, and complete mechanical formula ground is piled up, and lacks variation, lacks originality.With reference to Fig. 2,, change more though troublesome 12 structures of educational toy are complicated.But troublesome 12 of toy can only be combined into geometric figures such as square, cuboid.

If can to design and produce out a kind of collection study, amusement of risking three-dimensional contourings such as animal, building, daily necessities be the puzzle of one by improving troublesome 12.Children can improve the understanding to mathematics in the process that plays with toys that uses one's hands and brains, strengthen spatial consciousness, edify the consciousness of creation.

The utility model content

The purpose of this utility model is to provide a kind of novel solid magic square of being made up of the sub-stereo block of 12 kinds of shapes of tridecyne.

The problem that the utility model solved can realize by the following technical solutions:

The novel solid magic square comprises the plurality of sub stereo block, and described plurality of sub stereo block comprises sub-stereo block of ' Z ' type and the sub-stereo block of at least two ' L ' types, altogether 12 kinds of shapes of tridecyne.

The sub-stereo block of described ' Z ' type comprises that a block unit square is respectively added in the upper right side of cuboid and lower left by the synthetic cuboid of two block unit squares, and then the sub-stereo block of synthetic ' Z ' type.

The sub-stereo block of described ' L ' type comprises that by the synthetic face that has of four block unit squares be foursquare cube, and a block unit square is added on cubical upper left side, and then the sub-stereo block of synthetic ' L ' type.

Beneficial effect: the novel solid magic square has changed the shortcoming that in the past can only piece together rectangle, cuboid figure, except being combined into geometric figures such as square, rectangle, square, cuboid, can also create three-dimensional contourings such as animal, building, daily necessities, and every kind of figure has several different spellings again, and the assembling method change is infinite.

Description of drawings

Fig. 1 is the stereogram of the sub-stereo block of tridecyne of novel solid magic square;

Fig. 2 is troublesome 12 a stereogram;

Fig. 3 is for to take the planar graph that is combined into by the novel solid magic square;

Fig. 4 is for to take the solid figure that is combined into by the novel solid magic square.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.

With reference to Fig. 1, Fig. 2, on troublesome 12 basis, the novel solid magic square comprises, sub-stereo block 1～11 also comprises sub-stereo block 12 of ' Z ' type and the sub-stereo block 13 of ' L ' type, common 12 kinds of shapes of tridecyne.

The sub-stereo block 12 of described ' Z ' type is by the synthetic cuboid of two block unit squares, and the entity of four unit cubes of block unit square formation is respectively added in the upper right side of cuboid and lower left.The sub-stereo block 13 of described ' L ' type is that the face that has that is synthesized by four block unit squares is foursquare cube, and the entity of five unit cubes of block unit square formation is added on cubical upper left side.

Fig. 3 is for to take the planar graph that is combined into by the novel solid magic square, and Fig. 4 takes the solid figure that is combined into for the novel solid magic square.Changed the shortcoming that in the past can only piece together rectangle, cuboid figure by the visible the utility model of Fig. 3, Fig. 4, except being combined into geometric figures such as square, rectangle, square, cuboid, can also create three-dimensional contourings such as animal, building, daily necessities, and every kind of figure has several different spellings again, and the assembling method change is infinite.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
