[0002] Puzzles are a type of manual educational toy. Puzzles come in various forms, including single-sided puzzles, double-sided puzzles, and 3D puzzles. Existing puzzle... Figure 1 Traditional puzzles typically involve piecing together fragments to form a complete shape. However, these puzzles are difficult for infants and toddlers to assemble and lack appeal and fun, failing to effectively engage them. Therefore, we propose an infinite puzzle using regular polyhedra. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an infinite puzzle of regular polyhedra to solve the technical problem that current puzzles lack appeal and fun in the process of assembling, and cannot effectively attract infants and young children.

[0006] Preferably, one protrusion on the outer periphery of the rectangular main body of the corner unit is integrally formed, and the other protrusion is rotatably connected.

[0007] Preferably, the iridescent color layer includes a color coating layer, which is applied to the surface of the rectangular body, and a photochromic coating layer is applied to the surface of the color coating layer.

[0008] Preferably, the bending connection structure includes a groove starting on the rectangular body and the recessed cavity, a connecting piece is installed between the rectangular body and the recessed cavity, and an elastic rope connects the rectangular body and the recessed cavity.

[0009] Preferably, the connecting piece consists of two adhesive layers and an intermediate soft layer. The two adhesive layers are respectively fixed to the rectangular body and the bottom of the recessed cavity, and the intermediate soft layer is located between the two adhesive layers and connected to each other.

[0010] Preferably, the elastic rope is in a non-stressed state when the protrusion is at a 45° angle to the rectangular body, and a vertical limiting stop is provided at the bottom of one of the adhesive layers.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes photochromic materials that change color under light of different intensities or wavelengths. When used with ordinary paint, it produces different appearances in illuminated and unilluminated areas, or in areas with different light intensities. Combined with different colors, different dazzling colors can be formed after each assembly, enhancing its fun and appeal. At the same time, the vertically bendable design of the corner unit allows for the assembly of different regular polyhedra, offering a high degree of freedom and further enhancing its fun and appeal. This solves the problem of puzzles lacking appeal and fun during assembly, failing to attract infants and young children effectively.

[0013] 2. This utility model also uses the design of the slot and the cooperation of the limiting stop, and the rotatable and bendable connection of the connecting piece, combined with the elastic design of the elastic rope, so that when the protrusion is bent at 90°, an elastic tension will be generated. Combined with the coordination of the tension direction, the protrusion can be tightened to keep it in a vertical state, which further solves the problem of poor stability of regular polyhedra when they are assembled.

[0022] like Figures 1 to 5 As shown, this utility model relates to an infinite puzzle of a regular polyhedron, including a straight-patch unit 1 and a corner unit 2. Both the straight-patch unit 1 and the corner unit 2 are composed of a rectangular body 101, recessed cavities 102, and protrusions 103. There are two protrusions 103 and two recessed cavities 102, symmetrically distributed on both sides. The rectangular body 101 is a flat rectangular structure. The recessed cavities 102 are located on the corresponding two sides of the rectangular body 101. The protrusions 103 and the recessed cavities 102 can fit together. A dazzling color layer 3 is provided on the surface of the straight-patch unit 1 and the corner unit 2. Color layer 3 includes color coating 301, which is applied to the surface of rectangular main body 101. The color coating 301 on each unit is designed with a different color. The surface of color coating 301 is coated with photochromic coating 302. By using different colored coatings and photochromic coating 302 in combination, the different colored coatings can be arbitrarily spliced ​​together to form a dazzling color effect. The splicing can be done at will, and different color splicing can have different dazzling color effects, which can improve fun and attractiveness and make it easier to attract infants and young children.

[0023] To achieve three-dimensional splicing, one protrusion 103 on the outer periphery of the rectangular main body 101 of the corner unit 2 is integrally formed, while the other protrusion 103 is rotatably connected. A bent connecting structure 4 is provided between the recessed cavities 102 on one side of the corner unit 2. The bent connecting structure 4 includes a groove 401 starting on the rectangular main body 101 and the recessed cavity 102. A connecting piece 42 is installed between the rectangular main body 101 and the recessed cavity 102. An elastic rope 403 connects the rectangular main body 101 and the recessed cavity 102. The connecting piece 42 consists of two... The structure consists of an adhesive layer 421 and an intermediate soft layer 422. The two adhesive layers 421 are fixed to the bottom of the rectangular body 101 and the recessed cavity 102, respectively. The intermediate soft layer 422 is located between the two adhesive layers 421 and is connected to each other. When the protrusion 103 is at a 45° angle to the rectangular body 101, the elastic rope 403 is in a non-stressed state. A vertical limit stop 404 is provided at the bottom of one of the adhesive layers 421. The design of the limit stop 404 can limit the rotatable protrusion 103 so that it can only rotate 90° in one direction.

[0024] Working principle: When splicing three-dimensional multifaceted parts, corner unit 2 is used at the corner position, and the protrusion 103 is bent. When the bent protrusion 103 is twisted to 90° and contacts the limit stop 404, the elastic rope 403 is stretched. Due to the change in the direction of the tension, the elastic rope 403 will tighten the protrusion 103 in the vertical state, making the three-dimensional multifaceted state more stable, further improving its fun and attractiveness, and providing high splicing freedom.

[0025] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
