Embodiment Construction

[0036] The present invention will be further described in conjunction with accompanying drawings.

[0037] An octagonal folding mechanism, which includes: a square sheet 16, first to fourth triangular sheets 2, 8, 13, 19, first to fourth bending rods 5, 10, 11, 17, through the first The first to sixth short adapters 1, 3, 7, 14, 15, 21, the first to fourth intermediate adapters 4, 6, 12, 20, and the first and second long adapters 9, 18 are connected into eight sides shape folding mechanism.

[0038] With the square sheet 16 as the base layer, the holes at the four right angles of the square sheet 16 are numbered clockwise from the first to the fourth; the upper end of the fourth transfer joint 20 passes through the holes at the right angles of the fourth triangular sheet 19, the first The lower end of four transfer joints 20 passes through the hole at the first right angle of the square sheet 16, the fourth triangular sheet 19 and the square sheet 16 are connected, the fourth...

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...
