Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a highly smooth and stable magic cube structure. Background Art

[0002] Since its invention by Hungarian architecture professor Rubik in 1974, the Rubik's Cube has quickly become a popular educational toy. As more and more Rubik's Cube racing enthusiasts and collectors pay more and more attention to the Rubik's Cube, the structural requirements of the Rubik's Cube are also gradually increasing, especially in terms of the smoothness and stability of rotation. The Rubik's Cubes currently on the market mainly enhance the smoothness of the Rubik's Cube by adding bearings, but maintenance such as oiling is required to ensure the smoothness of the bearings; and because only the center block in the Rubik's Cube is connected to the axis, the corner blocks and edge blocks are fixed with baffles. During long-term use, due to wear and force, the gaps between the corner blocks, edge blocks and center blocks will gradually increase, causing the Rubik's Cube to become loose as a whole, and then the Rubik's Cube will jam when rotating, affecting its use. Utility Model Content

[0003] The purpose of the present invention is to provide a rationally designed, highly smooth and stable Rubik's Cube structure to address the defects and shortcomings of the prior art, which can solve the above-mentioned defects.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: it includes an axis and a plurality of center blocks, edge blocks and corner blocks arranged on the outside of the axis, the center block is connected to the axis through a magnetic rotating structure, the inner sides of the edge blocks and corner blocks are respectively provided with arc-shaped baffles, the surfaces of the edge blocks opposite to the corner blocks and the center blocks and the surfaces of the center blocks opposite to the edge blocks are respectively provided with arc-shaped slide grooves, and the slide groove combination on the surfaces of the edge blocks and the center blocks located on the same plane in the Rubik's Cube is circular, and the three surfaces opposite to the corner blocks and the edge blocks are respectively installed with magnetic block 1 and several ball bearings, and the ball bearings are all arranged in the slide grooves, and the surfaces on both sides of the edge blocks opposite to the corner blocks are respectively provided with magnetic block 2 opposite to magnetic block 1.

[0005] Preferably, the magnetic rotating structure includes a movable magnetic block clamped in the central block, an "8"-shaped movable cavity is opened on the inner side of the movable magnetic block, a hole connected to the movable cavity is opened at the bottom of the movable magnetic block, a fixed column is provided in the hole, two ellipsoidal fixed magnetic blocks are installed on the fixed column, the two fixed magnetic blocks are respectively located in the two ellipsoidal parts of the movable cavity, the magnetic poles of the fixed magnetic block and the movable magnetic block are the same, and the outer dimensions of the fixed column and the fixed magnetic block are smaller than the inner dimensions of the movable cavity and the hole, a groove for connection is opened at the lower end of the fixed column, and the axis and the groove below the fixed column are connected by a connecting rod.

[0006] Preferably, the center block includes a square shell with an open top, an upper cover is connected to the shell through a bayonet, and a slot matching the shape of the movable magnetic block is provided at the bottom of the upper cover, and the movable magnetic block is arranged in the slot of the upper cover.

[0007] Preferably, the magnetic poles of the magnetic block 1 and the magnetic block 2 are opposite, and the outer surfaces of the magnetic block 1 and the magnetic block 2 are respectively lower than the outer surfaces of the corner block and the edge block.

[0008] Preferably, the surfaces of the chutes are provided with a wear-resistant coating.

[0009] Preferably, the Rubik's Cube is a three-order Rubik's Cube.

[0010] After adopting the above structure, the beneficial effects of the utility model are:

[0011] 1. This Rubik's Cube structure is equipped with a magnetic rotating structure. The fixed magnetic blocks are limited from multiple angles. The angles of the fixed columns and connecting rods relative to the movable magnetic blocks are restricted, and they will not shake left and right at will. The center block can be quickly installed through the upper cover, and the movable magnetic block is stuck in the center block. The installation is simple and convenient. When the center block rotates, the movable magnetic block rotates outside the fixed magnetic block. The fixed magnetic block and the movable magnetic block do not contact and no friction is generated. Therefore, when the Rubik's Cube is rotated, that is, when the center block rotates, it can rotate smoothly, which is smoother than the traditional Rubik's Cube's hinge structure.

[0012] 2. When the Rubik's Cube structure passes through the edge blocks and the center block during movement, the balls can roll in the chute without generating hard friction and the rotation is smooth. After rotating 90°, magnetic blocks 1 and 2 can attract each other under the action of magnetic force, which not only positions the Rubik's Cube without the need for manual judgment of the rotation angle, but also, under the action of magnetic force, the corner blocks are sucked tightly toward the edge blocks, keeping the balls in fit with the chute, which can lock the overall structure of the Rubik's Cube and maintain the overall stability of the Rubik's Cube. The Rubik's Cube will not become loose, thereby preventing the Rubik's Cube from getting stuck due to the increase of gaps due to long-term use and the subsequent change of shape.

[0013] 3. Compared with the bearing-type Rubik's Cube, this Rubik's Cube structure does not require oiling and maintenance operations because the fixed magnetic block and the movable magnetic block are separated. It can remain stable for long-term use without frequent maintenance and servicing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See Figures 1-4 As shown, the Rubik's Cube is a three-order Rubik's Cube, which includes an axis 1 and multiple center blocks 2, edge blocks 3 and corner blocks 4 arranged on the outside of the axis 1. The center block 2 is connected to the axis 1 through a magnetic rotating structure. The inner sides of the edge blocks 3 and the corner blocks 4 are respectively provided with arc-shaped baffles 9. The surfaces of the edge blocks 3 opposite to the corner blocks 4 and the center blocks 2 and the surfaces of the center blocks 2 opposite to the edge blocks 3 are respectively provided with arc-shaped slide grooves 6, and the slide grooves 6 on the surfaces of the edge blocks 3 and the center blocks 2 located on the same plane in the Rubik's Cube are combined in a circular shape. The three surfaces of the corner blocks 4 opposite to the edge blocks 3 are respectively installed with magnet blocks 1 7 and several balls 5, and the balls 5 are all arranged in the slide grooves 6. The surfaces on both sides of the edge blocks 3 opposite to the corner blocks 4 are respectively provided with magnet blocks 2 8 opposite to magnet block 1 7. The magnetic poles of magnet block 1 7 and magnet block 2 8 are opposite, and the outer surfaces of magnet block 1 7 and magnet block 2 8 are respectively lower than the outer surfaces of the corner blocks 4 and the edge blocks 3.

[0023] See Figure 1-Figure 5As shown, the magnetic rotating structure includes a movable magnetic block 203 clamped in the central block 2, an "8"-shaped movable cavity 204 is opened inside the movable magnetic block 203, a hole communicating with the movable cavity 204 is opened at the bottom of the movable magnetic block 203, a fixed column 205 is provided in the hole, two ellipsoidal fixed magnetic blocks 206 are installed on the fixed column 205, the two fixed magnetic blocks 206 are respectively located in the two ellipsoidal parts of the movable cavity 204, the magnetic poles of the fixed magnetic blocks 206 and the movable magnetic block 203 are the same, and the outer dimensions of the fixed column 205 and the fixed magnetic blocks 206 are smaller than the inner dimensions of the movable cavity 204 and the hole, a connecting groove is opened at the lower end of the fixed column 205, and the axis 1 and the groove below the fixed column 205 are connected by a connecting rod 10;

[0024] The center block 2 includes a square shell 201 with an open top. A top cover 202 is connected to the shell 201 through a bayonet. A slot matching the shape of the movable magnetic block 203 is provided at the bottom of the top cover 202, and the movable magnetic block 203 is arranged in the slot of the top cover 202.

[0025] As an optimization solution of the present invention, the movable cavity 204 in the movable magnetic block 203 allows the fixed magnetic block 206 to be restricted to the center of each circular portion in the movable cavity 204 under the action of magnetic force, and Figure 5 In the state shown, the two fixed magnets 206 are respectively limited from multiple angles, and the vertical angles of the fixed column 205 and the connecting rod 10 relative to the movable magnet 203 are limited, and they will not shake left and right at will.

Align the center block 2 and press it down so that the connecting rod 10 is inserted into the fixed column 205, and the installation of the center block 2 is completed. After the installation is completed, the Rubik's Cube can be used. When rotating the Rubik's Cube, on the one hand, since the movable magnetic block 203 and the fixed magnetic block 206 are separated, no additional friction and resistance will be generated at the shaft during rotation, and the Rubik's Cube can be rotated easily and conveniently. On the other hand, the corner block 4 passes through the edge block during movement. 3 and the center block 2, the ball 5 can roll in the slide 6 without generating hard friction, and the rotation is smooth. After rotating 90 degrees, the magnetic block 1 7 and the magnetic block 2 8 can attract each other under the action of magnetic force, which not only positions the Rubik's Cube without the need for manual judgment of the rotation angle, but also, under the action of magnetic force, the corner block 4 is sucked tightly to the edge block 3, keeping the ball 5 in contact with the slide 6, while the overall structure of the Rubik's Cube can be tightened inwards, maintaining the overall stability of the Rubik's Cube, and preventing the Rubik's Cube from becoming loose, thereby preventing the Rubik's Cube from getting stuck due to the increase of gaps due to long-term use and the change of shape.
