Description

Technical Field

[0001] The utility model belongs to the technical field of toys, and particularly relates to a square magnetic building block component. Background Art

[0002] Building blocks are deeply loved by people as a kind of toy with educational value and creativity. In recent years, in addition to traditional concave-convex building blocks, magnetic building blocks that can be magnetically assembled have become increasingly popular. They get rid of the limitations of traditional concave-convex assembled building blocks and have the advantages of flexible and diverse assembling methods, which is more conducive to developing children's imagination and creativity. For example, the Chinese utility model patent with the authorization announcement number CN214075054U discloses a new type of magnetic cube building block, which is composed of a cube frame, an upper square cover, and two types of magnets. The cube frame is provided with a cavity for placing magnets, and after the magnets are installed, regularly arranged magnetic poles are presented on the building block surface. However, this magnetic cube building block still has the following deficiencies:

[0003] First, since the magnetic poles of the magnets on each face of the building block are fixed, if the magnetic blocks on two opposite faces of two building blocks to be spliced have the same magnetic poles, there will be a problem that they repel each other and cannot be adsorbed to each other, resulting in inability to splice.

[0004] Second, even if the magnetic poles of two opposite faces of two building blocks are opposite to form an attraction, after the attraction, the two building block blocks 10 are also prone to relative rotation, and the rotation direction is perpendicular to the magnetic attraction direction. The rotation (rubbing) direction is as shown by the Figure 1 arc arrow, which affects the regularity of the entire spliced body. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies and provide a square magnetic building block component, any face of which can be attached and adsorbed to any face of other square magnetic building block components, and the building block components are not prone to rotation after adsorption.

[0006] Its purpose can be achieved according to the following solution: A square magnetic building block component, including a building block housing in the shape of a cube, which is assembled by a lower housing and an upper cover sheet. The lower housing includes a lower shell sheet integrally injection-molded and four side shell sheets on the front, back, left, and right sides; a support body is provided inside the building block housing; in the center of the support body is a central column body. Four upper cavities are connected to the upper part of the central column body. The horizontal projection shapes of the four upper cavities and the central column body form a cross. The cavity opening of each upper cavity faces upward; four lower cavities are connected to the lower part of the central column body. The shapes of the four lower cavities are symmetrically arranged with the four upper cavities up and down. The cavity opening of each lower cavity faces downward. The horizontal projection shapes of the four lower cavities and the central column body form a cross; the upper cavities and the lower cavities are collectively referred to as cavities; an inner end wall is formed at one end of each cavity close to the central column body; when the support body is placed into the lower housing and the upper cover sheet is closed, the cavity openings of the four upper cavities are covered by the upper cover sheet, the cavity openings of the four lower cavities are covered by the lower shell sheet, and one end of each cavity far from the central column body is covered by the corresponding side shell sheet. Each cavity forms a chamber that is closed on all six sides, namely up, down, left, right, front, and back; a magnet block is loosely fitted and stored in each chamber, and the size of the magnet block is such that it can freely flip inside the corresponding chamber.

[0007] The horizontal projection shape of the central column body is a square.

[0008] The utility model has the following advantages and effects:

[0009] First, when the square magnetic building block components of the utility model are spliced, since the magnet blocks are loosely fitted in the chambers and can freely flip in the chambers, during the splicing process, as long as any two faces of any two building blocks approach each other, regardless of the magnetic pole directions before approaching, the corresponding two magnet blocks will rotate relative to each other adaptively after approaching, so that the S pole of one magnet block rotates to align with the N pole of the other magnet block, enabling the two magnet blocks to be tightly attracted to each other. Therefore, any two faces of any two building blocks can be attached by magnetic force, and there is no possibility of mutual repulsion. The attachment method can be arbitrary, and the attached faces are not restricted or affected by the magnetism of the magnet blocks.

[0010] Second, the square magnetic building block component has six faces. No matter which face of the first square magnetic building block component is spliced with which face of the second square magnetic building block component, at least two groups or four groups of magnet blocks will form an attraction. In this way, due to the principle that two points determine a straight line, there will be no relative rotation (twisting) between the two square magnetic building block components.

[0024] Figure 3 and Figure 2 and Figure 9 and Figure 7 and Figure 8 and Figure 11 A square magnetic building block component as shown, comprising a building block housing in the shape of a cube, the building block housing being formed by splicing a lower housing and an upper cover sheet 1, the lower housing 2 including a lower shell sheet 21 integrally injection-molded and four side shell sheets 22 on the front, back, left and right sides; a support body 3 is provided inside the building block housing.

[0025] Figure 4 and Figure 3 andFigure 7 , Figure 6 As shown in Figure 6 , the center of the bracket body 3 is a central column 33, and the horizontal projection of the central column 33 is square in shape; four upper cavities 31 are connected to the upper part of the central column 33, and the horizontal projection shapes of the four upper cavities 31 and the central column 33 form a cross, as Figure 6 shown. The cavity opening of each upper cavity 31 faces upward; four lower cavities 32 are connected to the lower part of the central column 33, and the shapes of the four lower cavities 32 are symmetrically related to the four upper cavities 31 up and down. The cavity opening of each lower cavity 32 faces downward, and the horizontal projection shapes of the four lower cavities 32 and the central column 33 form a cross; the upper cavities 31 and the lower cavities 32 are collectively referred to as cavities; an inner end wall 30 is formed at one end of each cavity close to the central column 33.

[0026] Figure 11 , Figure 10 , Figure 9 , Figure 12 , Figure 8 shown. When the bracket body 3 is placed into the lower housing 2 and the upper cover plate 1 is closed, the cavity openings of the four upper cavities 31 are covered by the upper cover plate 1, the cavity openings of the four lower cavities 32 are shielded by the lower housing piece 21, and one end of each cavity away from the central column is shielded by the corresponding side housing piece 22. Each cavity forms a chamber that is closed on all six sides, top, bottom, left, right, front, and back; a magnet block 5 is loosely fitted and stored in each chamber, and the size of the magnet block 5 is such that it can freely rotate in the corresponding chamber.

[0027] When the square magnetic building block components of the above embodiment are spliced, since the magnet block 5 is loosely accommodated in the chamber and can freely rotate in the chamber, during the splicing process, as long as any two faces of any two building blocks approach each other, regardless of the magnetic pole direction of the magnet block 5 before approaching, the corresponding two magnet blocks 5 will rotate relative to each other adaptively after approaching, so that the S pole of one magnet block rotates to align with the N pole of the other magnet block, so that the two magnet blocks 5 can be tightly attracted to each other, as Figure 13 shown.

[0028] Among the six faces of the square magnetic building block components of the above embodiment, each of the upper and lower faces corresponds to four magnet blocks 5. The upper and lower faces are collectively referred to as the main faces, and each of the remaining four side faces corresponds to two magnet blocks 5. Therefore, when two square magnetic building block components are spliced, if the main faces of the two square magnetic building block components are abutted against each other, four groups of magnet blocks 5 will form an attraction; if one side face of one square magnetic building block component is abutted against the side face of the other square magnetic building block component, two groups of magnet blocks 5 will form an attraction, as Figure 13As shown; if the side surface of one square magnetic building block member abuts against the main surface of another square magnetic building block member, there are also two sets of magnet blocks 5 forming an attraction.
