Octagonal folding mechanism

Abstract

The invention relates to an octagonal folding mechanism. In the mechanism, a fourth triangular plate and a second triangular plate are connected to a first right-angle position and a second right-angle position of a square plate through a fourth medium adapter and a second medium adapter; a first triangular plate and a third triangular plate are connected to a third right-angle position and a fourth right-angle position of the square plate through a second short adapter and a fourth short adapter; one acute angle of the first triangular plate and the other acute angle of the second triangularplate are respectively connected with both ends of a first bending bar; the other acute angle of the third triangular plate and the other acute angle of the fourth triangular plate are respectively connected with both ends of a fourth bending bar; the other acute angle of the first triangular plate and one acute angle of the third triangular plate are respectively connected with both ends of a third bending bar; one acute angle of the second triangular plate and one acute angle of the fourth triangular plate are respectively connected with both ends of a second bending bar; and the octagonal folding mechanism is formed by the connection. The octagonal folding mechanism is suitable for manufacturing geometrical training aids, mechanism training aids and toys, can be easily self-assembled, and has the advantages that the octagonal folding mechanism is convenient to disassemble and can be connected firmly while the folding effect is realized.

Description

technical field

[0001] The invention relates to an octagonal folding mechanism, in particular to a multi-layer foldable scaling mechanism, which realizes changes in various geometric shapes and is suitable for making geometric teaching aids, mechanism teaching aids and toys. Background technique

[0002] At present, there are single-degree-of-freedom scaling mechanisms on the market, such as magic flower balls, magic disks, etc., which can realize the overall scaling of the mechanism, but they can only be used as ornamental toys, and their structural forms are fixed and cannot be disassembled. In other detachable geometric toys, such as building blocks and jigsaw puzzles, each module can be fixed mechanically. Once the connection relationship is fixed, the whole can no longer be changed. To complete other shape changes, multiple modules need to be reconnected. Contents of the invention

[0003] The technical problem to be solved by the present invention is that the structu...
