Description

Technical Field

[0001] The utility model relates to the technical field of magic cube toys, in particular to a ball-axis positioning magic cube stabilizing structure with a low-friction suspension design. Background Art

[0002] The Rubik's Cube is an educational toy invented in the 1970s. It has a rich variety of transformation combinations and challenges, and is widely used in toys and competitions. However, the traditional Rubik's Cube structure has some problems. The internal axis structure is relatively simple, only connecting and supporting the six center blocks, while the remaining corner blocks and edge blocks are limited by baffles. The Rubik's Cube is prone to jamming and turning corners during rapid rotation, and even the corner blocks may directly fall out of the Rubik's Cube. Moreover, the Rubik's Cube cannot be directly positioned. After rotation, the user needs to judge the rotation angle of the Rubik's Cube based on vision or touch. If it is not rotated into place, the next rotation can easily be hindered, which to a certain extent reduces the user experience and operating efficiency. Utility Model Content

[0003] The purpose of the present invention is to address the defects and shortcomings of the prior art and to provide a rationally designed low-friction suspension design of the ball-axis positioning Rubik's Cube stabilization structure, which can solve the above-mentioned defects.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: it includes a spherical axis, and a plurality of center blocks, corner blocks and edge blocks forming a cubic outer structure are arranged on the outside of the axis. The inner shapes of the plurality of center blocks, corner blocks and edge blocks are combined into a spherical cavity. Several center shafts are installed on the axis through a rotating positioning assembly. The center shafts are respectively connected to each center block. An arc-shaped baffle 2 is provided on the inner side of each edge block. Several first magnetic blocks are provided on the axis, and an arc-shaped baffle 1 and a connecting rod are respectively provided on the inner side of each corner block. The top end of the connecting rod is connected to a second magnetic block opposite to the first magnetic block.

[0005] Preferably, the rotary positioning assembly includes a rotating seat installed on the axis, a rotating bearing is provided on the inner side of the rotating seat, and the central shaft is rotatably installed in the rotating seat through the rotating bearing. Several movable grooves are evenly opened along the circumference of the inner side of the rotating seat, each movable groove is provided with a steel ball, and a spring is provided on the back side of the steel ball. Grooves matching the shape of the steel balls are respectively opened on the outer side of the central shaft corresponding to the steel balls, and the steel balls are respectively clamped in the grooves.

[0006] Preferably, the first magnetic block and the second magnetic block have opposite polarities, and a gap is left between them.

[0007] Preferably, the number of the movable slots is an integer multiple of four.

[0008] Preferably, the outer sides of the corner blocks, edge blocks and center blocks are all provided with concave gripping grooves.

[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 structure is designed with the first and second magnetic blocks. The magnetic force makes the corner blocks of the Rubik's Cube automatically sucked inward and clamped, which enhances the stability of the Rubik's Cube and reduces the problem of the Rubik's Cube jamming. At the same time, the magnetic blocks do not directly contact each other, but leave a gap, so there is no friction during rotation, thereby reducing the rotational resistance. At the same time, when the Rubik's Cube is rotated into place, the magnetic blocks can attract each other to achieve fast and accurate positioning.

[0012] 2. This structural design uses a rotating positioning assembly to reduce the resistance during rotation by rotating the bearing, and uses a spring to clamp the steel ball into the groove, so that the center block can be quickly positioned, and then the rotating surface of the Rubik's Cube can be quickly positioned, improving the positioning efficiency and accuracy of the Rubik's Cube. During the rotation of the Rubik's Cube, the user can confirm whether it has been rotated into place based on the feedback of the Rubik's Cube's feel without the need for secondary confirmation.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See Figure 1-Figure 3 As shown, it includes a spherical axis 1, and the Rubik's Cube is a three-order Rubik's Cube. Six center blocks 4, eight corner blocks 5 and twelve edge blocks 6 that constitute the outer structure of the cube are arranged on the outside of the axis 1. The inner shapes of the center blocks 4, corner blocks 5 and edge blocks 6 are combined into a spherical cavity. Several center shafts 2 are installed on the axis 1 through a rotating positioning component. The center shafts 2 are respectively connected to each center block 4. An arc-shaped baffle 2 11 is provided on the inside of each edge block 6. Several first magnetic blocks 3 are provided on the axis 1. An arc-shaped baffle 1 8 and a connecting rod 9 are respectively provided on the inside of each corner block 5. The top of the connecting rod 9 is connected to a second magnetic block 10 opposite to the first magnetic block 3. The first magnetic block 3 and the second magnetic block 10 have opposite polarities, and a gap is left between them.

[0022] See Figure 1-Figure 5 As shown, the rotation positioning assembly includes a rotating base 12 installed on the axis 1, and a rotating bearing 13 is provided on the inner side of the rotating base 12. The central shaft 2 is rotatably installed in the rotating base 12 through the rotating bearing 13. Four movable grooves 14 are evenly opened along the circumference of the inner side of the rotating base 12, and each movable groove 14 is provided with a steel ball 16. The rear side of the steel ball 16 is provided with a spring 15. The outer side of the central shaft 2 is respectively provided with grooves matching the shape of the steel ball 16 at the corresponding positions of the steel ball 16, and the steel balls 16 are respectively clamped in the grooves.

[0023] As an optimization solution of the present invention, the smoothness of the rotation of the center shaft 2 and the center block 4 can be further enhanced by rotating the bearing 13, and the spring 15 is provided to push the steel ball 16 into the groove of the center shaft 2, so that the angle of the center shaft 2 can be limited. When rotating, the center shaft 2 can push the steel ball 16 back into the movable groove 14 until the center shaft 2 rotates to 90°, and the steel ball 16 is stuck in the groove again, so that the user can judge whether the Rubik's Cube is rotated into place according to the feel.

[0024] See Figure 1-Figure 2 As shown, the outer surfaces of the corner blocks 5, edge blocks 6 and center block 4 are all provided with concave gripping grooves 7.

[0025] As an optimization solution of the present invention, a gripping groove 7 is provided so that the user can better grip the Rubik's Cube when rotating it to prevent it from slipping.

[0026] The use process of this utility model:

[0027] First, assemble the Rubik's Cube and use it. Under normal conditions, the first magnetic block 3 and the second magnetic block 10 will attract each other, thereby pulling the corner block 5 inward, that is, when it is rotated into place, the magnets automatically attract and position the Rubik's Cube, and the stability and positioning sense will be greatly enhanced. Moreover, since there is a gap between the two magnetic blocks, the magnetic blocks will not cause friction due to rotation. At the same time, the rotation positioning component can automatically get stuck and give feedback to the user every 90° rotation during the rotation of the Rubik's Cube, so that the center block 4, corner block 5 and edge block 6 on the entire rotating surface can maintain the correct angle. When rotating the Rubik's Cube, the user can quickly operate according to the feel without having to judge whether the Rubik's Cube is rotated into place. In design and production, the number of steel balls 16 can also be multiplied according to the user's preferences and needs, so that the Rubik's Cube can be positioned and feedback when rotated to 45°, 22.5° and other angles.
