[0050] This embodiment relates to a magnetic four - order Rubik's Cube, as Figures 1-3 shown, a magnetic four - order Rubik's Cube includes corner blocks 1, edge blocks 2, center blocks 3 and an axis assembly 4; the corner blocks 1 and the edge blocks 2 are arranged adjacent to each other; the surfaces of the corner blocks 1 and the edge blocks 2 are arranged in an arc - shaped concave shape, such as Figure 2 the area A shown. In this way, this design makes the holding feeling better, enables the finger pads to contact the surfaces of the corner blocks 1 and the edge blocks 2 of the Rubik's Cube more closely, and is not easy to slip. It allows players not to worry about the problem of slipping during the process of rotating and restoring the Rubik's Cube, so as to perform at a better level.

[0051] Furthermore, as Figures 3-4 shown, a first anti - sticking groove 11 is provided on the outer wall of each corner block 1; a second anti - sticking groove 21 is provided on the outer wall of each edge block 2; optionally, the first anti - sticking groove 11 and the second anti - sticking groove 21 are in a turtle - back pattern, which can better store the Rubik's Cube lubricant in the anti - sticking grooves, prevent adhesion between the various components of the Rubik's Cube, and reduce the resistance of rotational friction to the lowest level, enabling the Rubik's Cube to quickly enter the best state.

[0052] Furthermore, a plurality of first magnet blocks 12 and a plurality of first magnetic force bins 13 are provided on the inner wall of each corner block 1, and the first magnet blocks 12 are installed in the first magnetic force bins 13; on the inner wall of the edge block 2 adjacent to the corner block 1, a second magnet block 22 and a second magnetic force bin 23 are provided, and the second magnet block 22 is installed in the second magnetic force bin 23; the first magnet blocks 12 and the second magnet blocks 22 are arranged such that opposite poles attract each other. In this way, when the Rubik's Cube rotates, it can quickly return to its position.

[0053] The first magnetic bin 13 and the second magnetic bin 23 are made of transparent materials, thus forming a visible magnetic bin, which is convenient for players to observe and adjust.

[0054] Specifically, as Figures 6-8 shown, second adjustable magnetic blocks 24, second fixed magnetic blocks 25 and second adjustable magnetic bins 26 are respectively installed on the inner walls of two adjacent edge blocks 2, and the second adjustable magnetic blocks 24 and / or the second fixed magnetic blocks 25 are installed in the second adjustable magnetic bins 26.

[0055] Specifically, as Figures 6-8 shown, the second adjustable magnetic blocks 24 on one adjacent edge block 2 and the second adjustable magnetic blocks 24 on the other adjacent edge block 2 form attraction between opposite poles. That is, the first magnet block 12 at the corresponding position is at the N pole, while the second magnet block 22 is at the S pole, or vice versa.

[0056] Specifically, as Figure 9 shown, an adjusting column 27 with a cavity is arranged in the second adjustable magnetic bin 26. The inner wall of the second adjustable magnetic bin 26 is provided with internal threads, the adjusting column is provided with external threads, and the adjusting column is installed in the second adjustable magnetic bin 26 by means of threaded connection. The second adjustable magnetic block 24 is arranged in the cavity of the adjusting column. The second adjustable magnetic bin 26 is made of transparent material, which is also convenient for players to observe and adjust.

[0057] It should be noted that the end face of the adjusting column 27 is provided with a fastening groove, which is an internal hexagonal shape or an internal plum blossom shape, so as to facilitate the use of a magnetic adjusting tool (such as a screwdriver or other screw drivers) to adjust the position of the adjusting column. Specifically, by loosening or tightening the adjusting column to change the relative position between the adjusting column 27 and the second adjustable magnetic bin 26, when the position of the adjusting column 27 changes, the second adjustable magnetic block 24 installed in its inner cavity changes synchronously; in this way, the distance between the second adjustable magnetic blocks 24 on two adjacent edge blocks 2 can be adjusted to change the magnetic force, so as to meet the requirements of more players for the magnetic force of the fourth-order Rubik's Cube. In this way, an adjustable visible magnet design is formed.

[0058] Specifically, as Figures 10-13 shown, it further includes a support frame 5, and the support frame 5 is connected to the axis assembly 4. Specifically, a screw rod is arranged on the support frame 5, and the axis assembly 4 is provided with an internal threaded column, and the screw rod and the internal threaded column are connected by means of threaded connection to make the structure stable.

[0060] A first-layer central piece 51 and a second-layer central piece 52, where the first-layer central piece 51 is used to support the inner edge support block 28, and the second-layer central piece 52 is used to support the edge block 2 and the corner block 1. In this way, a double central layer is formed. When rotating, each layer is controlled by an independent central piece and will not interfere with each other, thus achieving the effects of stable structure, not easily deformed and not easily loosened.

[0061] Specifically, as Figures 10-13 shown, the support frame 5 further includes a waist-binding piece 53, and the waist-binding piece 53 is located

[0062] between the second-layer central piece 52 and the inner edge support block 28. The waist-binding piece 53 is provided with a notch 531. Correspondingly, the inner edge support block 28 is provided with a convex bone 281, and the convex bone 281 is embedded in the notch 531. In this way, when rotating the Rubik's Cube, the inner edge support block 28 and the waist-binding piece 53 always maintain an inserted state, so as to achieve the effects of stability and not easily deformed.

[0063] Specifically, as Figures 12-13 shown, each corner block 1 is provided with a first clamping foot 14, the upper end surface of the first clamping foot 14 is provided with a clamping groove, and each inner edge support block 28 is provided with a second clamping foot, and the second clamping foot is clamped in the clamping groove. With such a setting, the Rubik's Cube rotates more smoothly.

[0064] Specifically, as Figure 14 shown, the axis assembly 4 includes a central axis and a plurality of core magnets 42. Preferably, the number of core magnets 42 is 8, and they form opposite-pole attraction with the magnets on the first clamping feet 14 of the corner blocks 1, so that the Rubik's Cube can easily return to its position under the action of magnetic force before it has rotated back in place.

[0065] Specifically, the number of corner blocks 1 is 8, the number of edge blocks 2 is 24, and the number of first magnet blocks 12 and first magnetic force bins 13 are both 3.
