Description

Technical Field

[0001] This utility model relates to the field of Rubik's Cube technology, specifically to a hollow five-sided Rubik's Cube structure. Background Technology

[0002] The hollow Rubik's Cube, as its name suggests, has its center piece removed, making its structure more unique compared to traditional Rubik's Cubes. The hollow 5x5 Rubik's Cube is a 5x5 cube with its center piece removed. Existing hollow 5x5 cube structures use interlocking tracks, which results in stuttering and uneven rotation, leading to a poor user experience. Furthermore, its poor fault tolerance and gaps in the track fit make it loose and prone to falling apart, hindering the improvement of the cube's rotation speed. Utility Model Content

[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a hollow five-cube structure to achieve a compact overall structure, smoother and more stable rotation, and fault tolerance.

[0004] This utility model provides a hollow five-dimensional cube structure, including a first shaft and a second shaft, which are plugged into and fixed to form a hollow shaft. The hollow shaft includes multiple faces and multiple corners. The hollow five-dimensional cube structure also includes multiple hollow core blocks, pressure blocks, spring components, and fixing blocks. Each face of the hollow shaft is provided with a cylindrical groove, and the hollow core block is rotatably installed in the cylindrical groove. Each corner of the hollow shaft is provided with a positioning post, and the pressure block is installed in the positioning post and can move up and down relative to the positioning post. The hollow core block includes an upper first inner cylindrical surface and a lower cylindrical boss. The pressure block is locked on the cylindrical boss, and the fixing block is fixed on the first inner cylindrical surface and can rotate under the drive of the hollow core block.

[0005] This invention relates to a hollow 5-piece cube. The hollow shaft includes 12 faces and 12 corners, corresponding to 12 hollow core blocks and 12 pressure blocks. Therefore, this invention has 12 cylindrical grooves on the 12 faces of the hollow shaft for fixing the cylindrical bosses of the hollow core blocks, allowing the hollow core blocks to rotate within the grooves. The 12 corners of the hollow shaft are provided with 12 cylindrical screw holes for fixing the 12 pressure blocks and limiting their orientation. The first shaft and the second shaft are fixed by interlocking.

[0006] This invention utilizes a detachable hollow shaft composed of a first shaft and a second shaft as the center positioning of the product, resulting in higher overall stability.

[0007] Furthermore, the pressure block is provided with a spring chamber, and the spring is installed in the spring chamber by means of a screw and locked at each corner of the hollow shaft.

[0008] This invention utilizes an elastically fixed pressure block, forming a hollow core block elastic system composed of a hollow shaft and 12 spring-loaded pressure blocks. The pressure blocks are locked to the 12 corners of the hollow shaft using springs and screws. Each pressure block has three blades that press against the cylindrical protrusions of adjacent hollow core blocks, giving the hollow core blocks an inward elastic force and improving the user experience during rotation.

[0009] Furthermore, the hollow shaft body is provided with multiple positioning grooves on the outer periphery of the positioning post for fixing the pressure block. The positioning grooves are concave, and the bottom of the pressure block is provided with a positioning protrusion that matches the positioning groove, so that when the pressure block is inserted into the positioning post, the positioning protrusion engages with the positioning groove, preventing the pressure block from rotating relative to the hollow shaft body.

[0010] Furthermore, the pressure block is provided with multiple first oil guide holes.

[0011] Furthermore, the first and second shafts are provided with multiple buckles on their sides for fixing the hollow block. First, the first and second shafts are fixed to each other by plugging and unplugging. Then, by setting multiple buckles, the hollow block can be fixed on the hollow shaft.

[0012] Furthermore, the fixing block includes multiple corner blocks and multiple edge blocks; the edge blocks are provided with a second inner cylindrical surface and a first outer cylindrical surface; the corner blocks are provided with a second outer cylindrical surface; the first inner cylindrical surface presses against the second inner cylindrical surface; the second inner cylindrical surface presses against the second outer cylindrical surface, so that the edge blocks and corner blocks can rotate and move within the first inner cylindrical surface and the second inner cylindrical surface, respectively.

[0013] Furthermore, the prism block includes a prism block foot and two prism block pieces; the two sets of prism block pieces are fastened to the groove by male and female nails, and a first slot is provided at the bottom; the top two ends of the prism block foot are provided with insert pieces, and the other side is provided with a second oil guide hole; the two sets of prism block pieces are fixedly connected by the insert post and the insert hole; and are respectively connected to the insert piece through the first slot; the second inner cylindrical surface and the first outer cylindrical surface are provided on the upper edge of the prism block foot.

[0014] Furthermore, the corner block includes corner block feet and three sets of corner block pieces; the corner block feet are provided with three sets of protrusions, and the corner block pieces are provided with a second slot that matches the protrusions.

[0015] Furthermore, the edge block is provided with a first magnet groove; the corner block is provided with a second magnet groove; magnets are fixed on the first magnet groove and the second magnet groove respectively; and the corner block is also provided with a plurality of triangular oil storage grooves.

[0016] There are 20 corner blocks and 30 edge blocks. The first inner cylindrical surface of the 12 hollow blocks, shaped like hats, can press down on the edge block feet of the first outer cylindrical surface of the edge blocks, thus fixing the 30 edge blocks. The edge blocks can rotate and move. Similarly, the side wings of the 30 edge blocks are provided with a second inner cylindrical surface and a first outer cylindrical surface. The second inner cylindrical surface presses down on the corner block feet of the second outer cylindrical surface of the corner blocks, thus limiting and fixing the 20 corner blocks, while allowing the corner blocks to rotate and move on the second inner cylindrical surface.

[0017] The corner block consists of three corner pieces, one corner block retainer, and three magnets. Each corner piece has a second slot, and the corner block retainer has a protrusion that engages with the second slot for secure fastening. Each corner piece has a magnet groove for securing the magnet, which is then glued in place. The inner wall of the corner block body has a triangular anti-stick oil reservoir. The edge block consists of two edge pieces, one edge block retainer, and two magnets. The two edge pieces are secured with male and female pins, and the edge block retainer has a tab that engages with the first slots of the two edge pieces for secure fastening. The edge pieces have magnet grooves for securing the magnet with glue. The edge block retainer has an oil guide hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The hollow five-piece Rubik's Cube of this invention has a compact overall feel, smoother and more stable rotation performance, is less prone to jamming, and has higher fault tolerance. The more compact track spacing makes it more stable. At the same time, the multi-layer embedded installation method helps to improve the rotation speed of the Rubik's Cube and improve the user experience. Attached Figure Description

Combined with... Figure 3 As shown, each surface of the hollow shaft 10 is provided with a cylindrical groove 102, which, combined with Figure 4 As shown, the hollow block 3 is rotatably installed in the cylindrical groove 102; each corner of the hollow shaft 10 is provided with a positioning post 103, and the pressure block 4 is installed in the positioning post 103 and can move up and down relative to the positioning post 103.

[0038] Combination Figures 6-7 As shown, the hollow block 3 includes an upper first inner cylindrical surface 31 and a lower cylindrical boss 32; combined with Figure 4 As shown, the pressure block 4 is locked onto the cylindrical boss 32. Therefore, the hollow shaft 10 has twelve cylindrical grooves 102 on its twelve faces, used to fix the cylindrical boss 32 of the hollow core block 3, and allowing the hollow core block 3 to rotate within the cylindrical grooves 102.
