Embodiment Construction

[0025] Triangular parts plugged into a three-dimensional shape, which is formed by plugging together 20 identical parts from part 1, part 2...part 20; the dotted line is used to indicate the positive fold line of the front half, that is, when folding, the front side of the paper and the front side are attached; the solid line The circle indicates the anti-folding line of reverse-folding, that is, when folding, the reverse side of the paper and the reverse side stick together; the arrow line indicates the indicator line of the insertion direction, the dotted part of the arrow line indicates the inserted part, and the solid line part of the arrow line indicates that it is not inserted part;

[0026] Take a rectangular paper that is horizontally long and vertically wide, and make three vertical fold lines perpendicular to the long side of the rectangular paper, and divide the rectangular paper into four small rectangles, namely, from left to right, the first small rectangle, the s...

Abstract

The invention provides a triangular part plugged-connection stereoscopic shape and relates to a manufacturing method of the stereoscopic shape. The stereoscopic shape is formed by 20 same parts through plugged connection. A piece of rectangular paper is divided into four small identical rectangles, the length-to-width ratio of each small rectangle is 1:0.5774, and the small rectangles are folded along longitudinal reverse-folding lines to form the stereoscopic shape defined by three sides, folded along diagonal forward-folding lines to form a multilateral shape and folded along connecting forward-folding lines and angular bisectors to form a part provided with a folded plug-in portion and a folded plugged opening. One folded plug-in portion 2 of the part 1 is inserted into the folded plugged opening. By adopting the plugged connection, a part 2 is plugged into a part 3, the part 3 is inserted into a part 4, the part 4 is plugged into a part 5, and the part 5 is plugged into the part 1, namely a pentagonal combined part is formed. By adopting the plugged connection, 20 parts are subjected to the plugged connection to form the triangular part plugged-connection stereoscopic shape formed by 12 pentagonal combined parts. The triangular part plugged-connection stereoscopic shape is ingenious in concept, novel in design, attractive and elegant in appearance, sound and firm. The parts are easy to manufacture, and combined plugged connection is simple.

Description

technical field [0001] The invention relates to a method for making a three-dimensional shape, in particular to a method for making a plug-in three-dimensional shape. Background technique [0002] At present, the known plug-in three-dimensional triangular parts are composed of two isosceles triangles, and the combination of the two triangles is not tight and easily deformed, resulting in weak plug-in. Contents of the invention [0003] In order to overcome the problem that the existing three-dimensional triangular component for plugging is composed of two isosceles triangles, and the combination of the two triangles is not tight, and it is easy to deform, resulting in an insecure plug. The invention provides a triangular component plug Connect the three-dimensional shape. [0004] The technical solution adopted by the present invention to solve the technical problem is: the triangular parts are plugged into a three-dimensional shape, which is formed by plugging together 2...
