Description

Technical Field

[0001] The present invention relates to the technical field of magic cubes, and in particular to a magic cube with conveniently adjustable rotation performance. Background Art

[0002] Rubik's Cube includes odd-order Rubik's Cube and even-order Rubik's Cube. Common odd-order Rubik's Cubes include 3x3 Rubik's Cube, 5x5 Rubik's Cube, 7x7 Rubik's Cube, 9x9 Rubik's Cube and 11x1 Rubik's Cube. Among them, 3x3 Rubik's Cube is the most common, and the most common even-order Rubik's Cube is 2x2 Rubik's Cube.

[0003] Among them, the main body of the three-order Rubik's Cube is a square structure, including twenty-six small cubes and a central axis. The small cubes include six center blocks located at the center of each face of the Rubik's Cube, eight corner blocks located at the end corners of the Rubik's Cube, and twelve edge blocks located between two adjacent corner blocks. In this way, each face of the Rubik's Cube has nine small cubes. Based on the rotation characteristics of the central axis, each layer of the Rubik's Cube can rotate freely.

[0004] In order to attract more people to love Rubik's Cube, Rubik's Cube competitions are held. During the competition, contestants need to rotate quickly in order to complete the rearrangement of the Rubik's Cube in the shortest time.

[0005] To meet the requirements of fast turning in Rubik's Cube competitions, a Chinese invention patent with publication number CN110038293A discloses a Rubik's Cube with adjustable turning performance. This Rubik's Cube with adjustable turning performance uses rotating blocks and floating pieces to adjust the turning performance of the Rubik's Cube, thereby optimizing the playing experience.

[0006] The above-mentioned prior art solutions have the following drawbacks: First, although the aforementioned Rubik's Cube can adjust the wheelbase of the center block through the floating member, thereby adjusting the rotation performance of the Rubik's Cube, due to the simple structure of the three-dimensional cross axis, its various sub-axes cannot be linked together, resulting in the floating member set in the center block being unable to link together. Therefore, the wheelbase of the center block can only be adjusted by adjusting the floating members in the center block one by one, which is relatively cumbersome. Moreover, it is difficult to ensure that the wheelbases of multiple center blocks after adjustment are equal, thereby affecting the playing experience of the Rubik's Cube. Second, the rotating blocks on the corner blocks and edge blocks can only be rotated individually to adjust the single magnet on the corner block or edge block, thereby adjusting the rotation performance of the Rubik's Cube. However, only one rotating block can be adjusted at a time, which is inefficient. Typically, there are two magnets in the edge block and three magnets in the corner block. That is, to adjust the magnetic force of the edge block or corner block, at least two magnets must be adjusted. Since the magnetic force of the edge block or corner block is manually adjusted, it is difficult to adjust the magnets in the corner block and edge block to the same distance. As a result, the magnets in the corner block and edge block have different effects, which in turn affects the rotation performance of the Rubik's Cube. Summary of the Invention

[0059] Reference Figure 11 and Figure 12The corner block body 3 includes a corner block shell 31 and three corner block shell covers 32 that cover the corner block shell 31. Assembly surfaces 321 are provided on adjacent two sides of one side of the corner block shell cover 32. The assembly surface 321 is provided with an assembly groove 3211, and the other assembly surface 321 is provided with an assembly bar 3212 that matches the assembly groove 3211. The assembly bar 3212 of the corner block shell cover 32 is inserted into the assembly groove 3211 of the other corner block shell cover 32, so that the assembly surface 321 of the corner block shell cover 32 is fitted with the assembly surface 321 of the other corner block shell cover 32, thereby realizing the assembly of the two corner block shell covers 32; the assembly groove 3211 is preferably a dovetail groove to limit the assembly bar 3212 from escaping from the assembly groove 3211, so that the two corner block shell covers 32 are more fixed. On the other two adjacent sides of one side of the corner block cover 32, there are provided snap-fitting strips 322 and snap-fitting slots 323 that mate with the opening of the corner block housing 31. The snap-fitting strips 322 are located inside the snap-fitting slots 323 and are connected to the assembly surface 321. When the corner block cover 32 covers the corner block housing 31, the snap-fitting slots 323 abut against the opening of the corner block housing 31, and the snap-fitting strips 322 abut against the opening of the corner block housing 31 and snap-fit ​​with the inner wall of the corner block housing 31, thereby completing the assembly of the corner block cover 32 and the corner block housing 31. A positioning slot 324 is provided at the bottom of the snap-fitting slot 323. A positioning strip 313 is provided at the opening of the corner block housing 31 that mates with the positioning slot 324. The positioning strip 313 snaps into the positioning slot 324 to reduce deformation of the corner block housing 31 and the corner block cover 32. The corner block cover 32 is equipped with an assembly rod 325 with a latching position. An assembly cylinder 314 is provided within the corner block housing 31, which matches the assembly rod 325. The assembly rod 325 latches into the cylinder 314, preventing the assembly rod 325 from being removed from the housing 31. A corner block foot 33 is removably connected to the bottom of the corner block housing 31. This foot 33 slides into the foot assembly 43 of the edge block body 4, facilitating rotation of the Rubik's Cube. Oil grooves are provided on the surfaces of both the corner block housing 31 and the corner block foot 33. These pyramid-shaped recesses facilitate oil storage.

[0060] The corner block housing 31 houses three magnetic components and a linkage mechanism 6 for simultaneously adjusting the three magnetic components. This linkage mechanism 6 comprises a fixed sleeve 61, a linkage gear 62, three drive gears 63, three adjustment covers 64, and three adjustment cylinders 65, with the magnetic components mounted within the adjustment cylinders 65. The bottom of the fixed sleeve 61 inserts into the corner block foot 33 to prevent it from disengaging from the corner block housing 31. The three-piece corner block housing cover 32 forms a cylinder, into which the top of the fixed sleeve 61 extends, further securing the fixed sleeve 61 within the corner block body 3. The linkage gear 62 and the drive gear 63 are both mounted on the fixed shaft sleeve 61. The linkage gear 62 and the drive gear 63 mesh, so that the three drive gears 63 and the linkage gear 62 are linked. The adjustment cover 64 is linked and sleeved on the drive gear 63. The outer wall of the drive gear 63 is provided with a clamping block 632. The adjustment cover 64 is provided with a clamping groove 641 that matches the clamping block 632. The clamping block 632 is clamped into the clamping groove 641, realizing the linkage between the adjustment cover 64 and the drive gear 63. Two threaded grooves 631 are provided in the drive gear 63. The outer wall of the adjustment cylinder 65 is provided with an adjustment rod 651 that matches the threaded grooves 631. The adjustment cylinder 65 extends into the drive gear 63 so that the adjustment rod 651 is clamped into the threaded groove 631, making the reciprocating motion of the adjustment cylinder 65 in the drive gear 63 more stable. A limit block 611 is provided at the end of the fixed sleeve 61. The cross section of the limit block 611 is set in the shape of a regular hexagon. Of course, the cross section of the limit block 611 can also be set in other polygonal shapes. The opening of the adjusting cylinder 65 is matched with the limit block 611. The adjusting cylinder 65 is sleeved on the limit block 611 to limit the rotation of the adjusting cylinder 65, so that the driving gear 63 drives the adjusting cylinder 65 to move back and forth in the driving gear 63. An adjustment hole 311 is defined in the sidewall of the corner block housing 31. An adjustment cover 64 is positioned within the adjustment hole 311. A drive slot 642 is defined at the end of the adjustment cover 64. The drive slot 642 is positioned within the adjustment hole 311, facilitating rotation of the adjustment cover 64 using a tool through the drive slot 642. The adjustment cover 64 rotates synchronously with the drive gear 63. The drive gear 63 drives the other drive gears 63 to rotate via the interlocking gear 62. Furthermore, since the adjustment cylinder 65 cannot rotate, the drive gear 63 drives the adjustment cylinder 65 to reciprocate within the drive gear 63, thereby simultaneously adjusting the three magnetic components within the adjustment cylinder 65 and, consequently, the magnetic components within the corner block body 3. The adjustment cylinder 65 is positioned within the adjustment cover 64 and within the adjustment hole 311, allowing the magnetic components within the adjustment cylinder 65 to more easily function. The outer wall of the corner block shell 31 is provided with several groups of second scales 312 for indicating the size of the magnetic force. The second scales 312 are arranged around the adjustment hole 311. The end of the adjustment cover 64 is provided with a second mark 643 facing the second scale 312 to facilitate the adjustment of the magnetic force exerted by the magnetic parts in the corner block body 3 according to the second scale 312.

[0061] In addition, refer to Figure 13 The linkage mechanism 6 within the corner block body 3 has another configuration. Since this linkage mechanism 6 is largely identical to the linkage mechanism 6 described above, the repeated parts will not be elaborated on. This linkage mechanism 6 differs from the linkage mechanism 6 described above in that: the drive gear 63 and the second scale 312, wherein the drive gear 63 is an incomplete gear, such as a gear with only half the number of teeth; the two sets of second scales 312 are correspondingly arranged on the outer wall of the corner block housing 31, and the two sets of second scales 312 are arranged on both sides of the adjustment hole 311. Since the drive gear 63 of this linkage mechanism 6 is incomplete, the rotation range of the drive gear 63 is theoretically reduced, thereby reducing the rotation range of the adjustment cover 64 and the adjustment cylinder 65; theoretically, the two linkage mechanisms 6 have the same effect on adjusting the magnetic member, and thus the same effect on adjusting the adjustment cylinder 65.

[0062] When the Rubik's Cube makes a tolerant movement or pulls the center block body 2, the center block shell 21 moves toward the center direction away from the center axis structure 1, and the oil storage part 251 and the pressing plate 252 follow the center block shell 21 to move toward the center direction away from the center axis structure 1, so that the oil storage part 251 and the pressing plate 252 are pressed toward the buckle block 2418 of the supporting top block 2412 at the same time, thereby squeezing the oil storage part 251, so that the oil in the oil storage part 251 is squeezed out from the pressure membrane flap 2513 of the oil outlet pipe 2511. The oil flows between the clamping foot assembly 43 and the corner block clamping foot 33, between the center block shell 21 and the edge block shell 41, and between the edge block shell 41 and the corner block shell 31. On the one hand, the Rubik's Cube between the clamping foot assembly 43 and the corner block clamping foot 33, between the center block shell 21 and the edge block shell 41, and between the edge block shell 41 and the corner block shell 31 is reduced, and the resistance to turning the Rubik's Cube is reduced, thereby optimizing the experience of playing the Rubik's Cube; on the other hand, the oil is stored in the oil tank to maintain the lubrication state between the clamping foot assembly 43 and the corner block clamping foot 33, between the center block shell 21 and the edge block shell 41, and between the edge block shell 41 and the corner block shell 31 for a long time, thereby maintaining better Rubik's Cube rotation performance for a long time.
