Abstract

A rhombic insertion sheet relates to a combined component. The rhombic insertion sheet is made from sheet material with toughness and is a rhombic sheet provided with interlayers. The two acute angles of the rhombic sheet are 60 degrees, and the two obtuse angles of the rhombic sheet are 120 degrees. The diagonal of the two obtuse angles is a folding line. The folding line is the fixing connection line of the two interlayers. The rhombic sheet is divided by the folding line into two exactly the same equilateral triangles. Two edges which are formed from one end point of the folding line to the two vertexes of the acute angles serve as the fixing connection lines of the interlayers. Two edges which are formed from the other end point of the folding line to the two vertexes of the acute angles serve as the openings of the interlayers. The rhombic insertion sheet is simple in line, easy in manufacturing, various in form and can be used for teaching and decoration. In addition, the combination of the insertion sheet can be simple or complex.

Description

The rhombus inserted sheet

Technical field

The utility model relates to a kind of component parts, especially a kind of geometric form plug-in unit.

Background technology

At present, known similar component parts has plenty of that paper makes, and each part all will be made separately, has increased the combination link; The component parts structure more complicated that has.

Summary of the invention

Have plenty of in order to overcome existing similar component parts that paper makes, each part all will be made separately, has increased the combination link; The deficiency of the component parts structure more complicated that has, the utility model provides a kind of rhombus inserted sheet.

The utility model solves the technical scheme that its technical matters adopted: the rhombus inserted sheet is made with the sheet material of flexible; The rhombus inserted sheet is a losenges with dissection; Two acute angles of rhombus are 60 degree, and two obtuse angles are 120 degree; The diagonal line at two obtuse angles is a fold line, and fold line i.e. the affixed line of two interlayers; Fold line is divided into rhombus at the equilateral triangle of two congruences; Two sidelines on end points to two of fold line acute angle summit are the affixed line of interlayer; Two openings that the sideline is an interlayer on another end points to two of fold line acute angle summit.

The beneficial effect of the utility model is that rhombus inserted sheet lines are simple, make easily; But the combination Yi Kenan of inserted sheet is various informative; Can be used for teaching and decoration.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the planimetric map of rhombus inserted sheet;

Fig. 2 is that three rhombus inserted sheets are pegged graft in twos, forms the stereographic map of the triangle geometry body of a depression;

Fig. 3 is that six rhombus inserted sheets are pegged graft in twos, forms the triangle geometry body stereographic map of two depressions of disjunctor;

Fig. 4 is pegged graft by more rhombus inserted sheets in twos, the spherical stereographic map of the triangle geometry body of 20 depressions of composition disjunctor.

Embodiment

The rhombus inserted sheet is made with the sheet material of flexible; The rhombus inserted sheet is a losenges with dissection; Two acute angles of rhombus are 60 degree, and two obtuse angles are 120 degree; The diagonal line at two obtuse angles is a fold line, and fold line i.e. the affixed line of two interlayers; Fold line is divided into rhombus at the equilateral triangle of two congruences; Two sidelines on end points to two of fold line acute angle summit are the affixed line of interlayer; Two openings that the sideline is an interlayer on another end points to two of fold line acute angle summit; Like Fig. 1.

Combined method: the equilateral triangle of a rhombus inserted sheet inserts the interlayer opening of another rhombus inserted sheet, overlaps with the equilateral triangle that is inserted into the rhombus inserted sheet.

Three rhombus inserted sheets are pegged graft in twos, can form the triangle geometry body of a depression; Like Fig. 2;

Six rhombus inserted sheets are pegged graft in twos, can form the triangle geometry body of two depressions of disjunctor; Like Fig. 3;

Peg graft in twos by more rhombus inserted sheets, can form the sphere of triangle geometry body of 20 depressions of disjunctor; Like Fig. 4.

The equilateral triangle of rhombus inserted sheet can be the insertion portion of assembly, also can be to be inserted into part, makes combination become simple, easy.

Claims

1. rhombus inserted sheet is characterized in that: the rhombus inserted sheet is made with the sheet material of flexible; The rhombus inserted sheet is a losenges with dissection; Two acute angles of rhombus are 60 degree, and two obtuse angles are 120 degree; The diagonal line at two obtuse angles is a fold line, and fold line i.e. the affixed line of two interlayers; Fold line is divided into rhombus at the equilateral triangle of two congruences; Two sidelines on end points to two of fold line acute angle summit are the affixed line of interlayer; Two openings that the sideline is an interlayer on another end points to two of fold line acute angle summit.
