Abstract

The utility model discloses a splicing block comprising a plurality of blocks. The utility model is characterized in that the block is a pentahedron cut from a regular tetrahedron; one surface of the pentahedron is rectangular, and the rest four surfaces are respectively isosceles triangles and isosceles trapezoids, which are symmetrically arranged; the trapezoid surfaces are divided into a plurality of triangle surfaces by dents arranged on the trapezoid surfaces of the pentahedron; the rectangular surface is also divided into a plurality of triangle surfaces by dents arranged on the trapezoid surface. The utility model has the advantages of simple structure and reasonable design. Children can know certain geometric principles and cultivate intelligence while splicing the blocks. Meanwhile, the design of the cross sections cut in different ways is puzzling and increases splicing difficulty. The utility model has good marketing prospects.

Description

The splicing building blocks

Technical field

The utility model relates to a kind of building blocks, particularly a kind of splicing building blocks.

Background technology

Building blocks wood or plastic solidification toy normally cube generally letter or picture at incrustation, allows and carries out different arrangements or carry out the construction activity building blocks that various patterns are arranged, and can develop children's intelligence, can be combined into the house, various animals etc.But traditional building blocks are confined to the simple combination of fundamental figure, do not have deeper content, and also do not have anything to be particular about on specification.But in the face of knowledge more and more important today, intellectual development has been not only that the simple of figure understood before children, therefore, invent a kind of more profound, more the splicing building blocks of geometry implications are arranged, be very important.

The utility model content

The purpose of this utility model: be intended to propose a kind of splicing building blocks, be confined to the simple graph combination, do not have the problem of how much implications to solve common splicing building blocks.

This splicing building blocks comprise some building blocks, it is characterized in that: two pentahedrons of described building blocks for being divided into by a positive tetrahedron.

Described pentahedron simultaneously is a rectangle, and four faces are symmetrical in twos in addition, are respectively isosceles triangle and isosceles trapezoid.

Have indenture on the described pentahedral trapezoidal faces, trapezoidal faces is cut into some gores.

Have indenture on the described pentahedral rectangular surfaces, rectangular surfaces is cut into some gores.

The utility model is simple in structure, and is reasonable in design, makes child in the splicing building blocks, understand certain geometrical principle, developed children's intelligence, simultaneously, the difference cutting design in cross section has tangible fascination, has increased the difficulty of splicing, and good market prospects are arranged.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model rectangular surfaces cutting schematic diagram.

Among the figure: the 1-pentahedron; The 11-rectangular surfaces; 12-isosceles triangle face; 13-isosceles trapezoid face; The gore that the 14-indenture forms; The 2-indenture.

The specific embodiment

As shown in Figure 1, this splicing building blocks comprise some building blocks, it is characterized in that: two pentahedrons 1 of described building blocks for being divided into by a positive tetrahedron.

Described pentahedron 1 one side is a rectangle 11, and four faces are symmetrical in twos in addition, are respectively isosceles triangle 12 and isosceles trapezoid 13, have indenture 2 on the pentahedral trapezoidal faces, and trapezoidal faces 13 is cut into three gores 14; Have indenture 2 on the pentahedral rectangular surfaces, rectangular surfaces 11 is cut into three gores 14.

Rectangular surfaces 11 splicings of two pentahedrons 1 by separately, isosceles triangle 12 bases of two pentahedrons 1 overlap with upper base with the isosceles trapezoid 13 of another pentahedron 1 respectively, and reconfiguring becomes a positive tetrahedron.

As shown in Figure 2, indenture 2 on two rectangular surfaces 11 is cut into three triangles 14 with rectangular surfaces, and respectively with the long and short limit of rectangular surfaces 11 as the triangle base with reference to the limit, two variform illusion of rectangular surfaces have been caused, in the process of splicing, produce certain fascination, increased the thinking of people in splicing.

Three triangles that cut into by indenture 2 of trapezoidal faces 13 provide the aesthetic property of building blocks, and seeming more has third dimension.Simultaneously, imparted rudimentary knowledge to beginners the geometrical principle that children's quadrangle can be made up of some triangles.

Building blocks integral body has the design of indenture 2, has also increased the frictional force of each face, makes that building blocks are difficult for dropping in splicing.

The utility model is simple in structure, and is reasonable in design, makes child in the splicing building blocks, understood certain geometrical principle, developed children's intelligence, and good market prospects are arranged.
