Description

Technical Field

[0001] The utility model belongs to the field of toys, and particularly relates to a square magnetic magic cube. Background Art

[0002] At present, magnetic Rubik's Cube toys have magnets on their edges, which are spliced ​​into various shapes through mutual adsorption for children to play with. Most of the current magnetic Rubik's Cube toys are square, triangular and polygonal plate-shaped, which are formed into three-dimensional shapes by splicing the plates. The plate structure designed for the current magnetic Rubik's Cube toys can only be connected horizontally and vertically during the splicing process. The three-dimensional model formed is single in form, cannot be well enriched and diversified, and cannot fully tap children's imagination. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a square magnetic Rubik's Cube, which forms a square structure on the outer shell by covering two sets of cover plates, and provides magnets for adsorption in the fitting grooves at the connection between the cover plates and the outer shell, so as to form a magnetic Rubik's Cube with a strong three-dimensional sense, which is easy to assemble and can enrich children's play combinations.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A square magnetic magic cube includes an outer shell, a plurality of magnets and two sets of cover plates. The outer shell is provided with an assembly cavity running through the upper and lower ends. The two sets of cover plates are detachably connected to the openings at the upper and lower ends of the outer shell. The connection between the outer shell and the cover plates is provided with a plurality of interlocking grooves for placing the magnets. The interlocking grooves are formed by two sets of interlocking half grooves abutting against each other and enclosing each other. The two sets of interlocking half grooves are respectively arranged on the outer shell and the cover plates.

[0006] The cam is provided with a plurality of grooves, each of which is provided with a plurality of grooves, and the plurality of grooves are connected to each other by a plurality of threaded holes, and the plurality of grooves are connected to each other by a plurality of threaded holes.

[0007] The square magnetic Rubik's Cube adopts this structure. In order to be able to be assembled into a square magnetic Rubik's Cube, the outer shell is used as the basis, and openings are opened at its upper and lower ends, and a closed square structure is formed by the embedded cover. In order to achieve the effect of magnetic adsorption, an interlocking groove for placing the magnet is provided at the connection between the outer shell and the cover. The interlocking groove is composed of two groups of interlocking half-grooves, and the two groups of interlocking half-grooves are respectively provided on the outer shell and the cover. Therefore, during assembly, the magnet is first placed into the interlocking half-grooves on the outer shell, and then the cover is installed. The two groups of interlocking half-grooves correspond to form a complete interlocking groove, thereby confining the magnet in the interlocking groove. Therefore, under the two groups of cover plates, the interlocking grooves are distributed at the four corners. After assembly is completed, the six faces of the square magnetic Rubik's Cube all have magnetic adsorption capabilities.

[0008] In order to embed the cover plate into the assembly cavity for fixation, male posts are provided on the cover plate, and female grooves are provided in the assembly cavity. Therefore, during the embedding process, the male posts are inserted into the female grooves to fix the cover plate. In order to strengthen the connection force between the male posts and the cover plate, transverse reinforcing ribs are provided at the connection, which not only strengthens the connection strength between the male posts and the cover plate, but also plays a more stable outward support role during the embedding of the transverse reinforcing ribs into the assembly cavity. In order to achieve a tighter connection between the shell and the cover plate, four groups of male posts are provided, and two groups of female grooves are provided in opposite directions, with the purpose of facilitating alignment and assembly. In the assembly process, if four groups of female grooves are provided to correspond to the four groups of male posts, it is very likely that two or three of them will be aligned during the assembly process, but the other female grooves will be difficult to align, making it difficult to complete the assembly. External force is required to pry the cover plate to achieve simultaneous alignment of the four groups, causing assembly difficulties. Therefore, two groups of female grooves are provided to solve the assembly problem well. Only one female groove needs to be aligned for assembly, and then the other female groove can be aligned by rotation. Direct embedding can successfully assemble, thereby improving assembly efficiency.

[0009] Since the shell is a square structure, only two female grooves are used to cooperate with the embedding and fixation of the male column, which is likely to cause misalignment in the other two positions where no male column is embedded, resulting in the cover plate at the connection being convex and causing scratches. Therefore, two sets of oppositely distributed embedding grooves are set in the assembly cavity, and the embedding groove openings face the assembly cavity. The other two sets of male columns move downward along the bottom of the embedding grooves during the embedding process of the assembly cavity. This embedding assembly method is different from the column-to-hole insertion, which requires complete and precise insertion. It only requires adjacent positions. During the gradual embedding process, the male column will gradually align and align with the embedding groove. Therefore, the outer wall of the shell will be corrected in the process of the embedding groove being embedded by the male column, thereby avoiding misalignment. In order to strengthen the structural stability of the shell and prevent deformation, a cross reinforcement rib is provided in the assembly cavity, each end of which is respectively connected to the two sets of female grooves and the two sets of embedding grooves, thereby achieving structural reinforcement and fixation inside the shell, and avoiding distortion of the shell under external force.

[0010] Furthermore, the shell and the cover plate are both provided with through holes communicating with the engaging grooves; and the outer side wall of the shell is provided with an attaching groove.

[0011] Compared with the existing technology, the advantages of the present invention are: by splitting the square Rubik's Cube into an outer shell and two sets of cover plates, the magnets are distributed on the four corners of the assembly of the outer shell and the cover plate, so that the six sides of the square Rubik's Cube all have magnetic adsorption effect, and simple assembly is achieved through two sets of interlocking half grooves. The cooperation of the set male column and the female groove can realize the fastening of the cover plate on the outer shell. For efficient assembly, two sets of corresponding female grooves are provided to engage with the male column. The other two sides are guided between the outer shell and the cover plate by embedded grooves, and the stability of the structure is maintained by the setting of cross reinforcement ribs.

The transverse reinforcing rib 31 is embedded in the assembly groove and abuts against the female groove 42.

[0024] Furthermore, the housing 1 and the cover plate 3 are both provided with a through hole 13 communicating with the fitting groove 12 ; and an attachment groove 14 is provided on the outer side wall of the housing 1 .

[0025] Description of the working method of this utility model:

[0026] The square magnetic Rubik's Cube adopts this structure. In order to be able to be assembled into a square magnetic Rubik's Cube, the shell 1 is used as the basis, and openings are opened at its upper and lower ends, and a closed square structure is formed by the embedded cover 3. In order to achieve the effect of magnetic adsorption, an interlocking groove 12 for placing the magnet 2 is provided at the connection between the shell 1 and the cover 3. The interlocking groove 12 is composed of two groups of interlocking half grooves 121. The two groups of interlocking half grooves 121 are respectively provided on the shell 1 and the cover 3. Therefore, during assembly, the magnet 2 is first placed into the interlocking half groove 121 on the shell 1, and then the cover 3 is installed. The two groups of interlocking half grooves 121 are correspondingly enclosed to form a complete interlocking groove 12, thereby restricting the magnet 2 in the interlocking groove 12. Therefore, under the two groups of cover plates 3, the interlocking grooves 12 are distributed at the four corners. After assembly is completed, the six faces of the square magnetic Rubik's Cube all have magnetic adsorption capabilities.

[0027] In order to embed the cover plate 3 into the assembly cavity 11 for fixation, a male column 41 is provided on the cover plate 3, and a female groove 42 is provided in the assembly cavity 11. Therefore, during the embedding process, the male column 41 is inserted into the female groove 42 to fix the cover plate 3. In order to strengthen the connection force between the male column 41 and the cover plate 3, a transverse reinforcing rib 31 is provided at the connection, which not only strengthens the connection strength between the male column 41 and the cover plate 3, but also plays a more stable outward stretching role during the embedding of the transverse reinforcing rib 31 into the assembly cavity 11. In order to strengthen the connection between the shell 1 and the cover plate 3, four groups of male columns 41 are provided, and the female groove 42 is provided. Two groups distributed in opposite directions are provided for the purpose of facilitating alignment and assembly. In the assembly process, if four groups of female grooves 42 are provided to correspond to four groups of male posts 41, it is very likely that two or three will be aligned during the assembly process, but the other female grooves 42 will be difficult to align, making it difficult to complete the assembly. External force is required to pry the cover plate 3 to achieve simultaneous alignment of the four groups, causing assembly difficulties. Therefore, two groups of female grooves 42 are provided to solve the assembly problem well. After aligning one female groove 42 for assembly, the other female groove 42 can be aligned by rotating it. Direct insertion can successfully assemble the group, thereby improving assembly efficiency.

[0028] Since the housing 1 is a square structure, only two female grooves 42 are used to fit the male posts 41 for embedding and fixing, which may cause the other two positions where no male posts 41 are embedded to be misaligned, causing the cover plate 3 at the connection to be convex and causing scratches. Therefore, two sets of oppositely distributed embedding grooves 43 are set in the assembly cavity 11, and the embedding grooves 43 open toward the assembly cavity 11. The other two sets of male posts 41 move downward along the bottom of the embedding grooves 43 during the process of embedding the assembly cavity 11. This embedding assembly method is different from the column-to-hole method which requires complete and precise insertion. The positions need to be adjacent. During the gradual embedding process, the male post 41 will gradually align and align with the embedding groove 43. Therefore, the outer wall of the shell 1 will be corrected in the process of the male post 41 being embedded in the embedding groove 43, thereby avoiding misalignment. In order to strengthen the structural stability of the shell 1 and prevent deformation, a cross reinforcement rib 44 is provided in the assembly cavity 11, each end of which is respectively connected to the two groups of female grooves 42 and the two groups of embedding grooves 43, thereby realizing structural reinforcement and fixation inside the shell 1 to avoid distortion of the shell 1 under the action of external force.

[0029] Due to negligence in assembly, the magnet 2 may not be fully installed and the cover 3 is assembled. The lack of one magnet 2 will affect the three sides of the magnetic cube. Although there are still three magnets 2 on each of these three sides, the adsorption force is far from enough. It is difficult to detect whether the magnet 2 is missing when the magnetic force is slightly missing in the subsequent quality inspection. Disassembling the cover 3 to check is equivalent to rework and reassembly, which is extremely inefficient. Therefore, a through hole 13 connecting the interlocking groove 12 is provided on the shell 1 and the cover 3, so that after the assembly is completed, it can be checked from the outside to know whether there is a magnet 2 inside, which improves the yield rate and reduces the workload of quality inspection.

[0030] The square magnetic magic cube is a toy for children to play with. An attachment groove 14 for stickers to be attached is provided on the outer wall of the toy. Patterns can be attached as needed to enrich the play form of the toy.

[0031] The beneficial effect of the present invention is that the square Rubik's Cube is assembled by splitting it into an outer shell 1 and two groups of cover plates 3, and the magnets 2 are distributed on the four corners of the assembly of the outer shell 1 and the cover plate 3, so that the six sides of the square Rubik's Cube all have magnetic adsorption effect, and simple assembly is achieved through two groups of interlocking half grooves 121. The cooperation of the set male column 41 and the female groove 42 can realize the fastening of the cover plate 3 on the outer shell 1. For efficient assembly, two groups of corresponding female grooves 42 are provided to interlock with the male column 41. The other two sides are guided between the outer shell 1 and the cover plate 3 by the embedded grooves 43, and the stability of the structure is maintained by the setting of cross reinforcement ribs 44.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
