Description

Technical Field

[0001] The utility model relates to the technical field of magic cubes, and in particular discloses a magnetic positioning magic cube with adjustable magnetic force. Background Art

[0002] The traditional Rubik's Cube is a 6-sided cube made of flexible hard plastic. The core is an axis and consists of 26 blocks. The 26 blocks include 6 inner center blocks, which are fixed and have only one side with color. 8 corner blocks can rotate. 12 edge blocks can also rotate. When the toy is sold, the blocks are arranged so that each side of the cube has the same color. When one side of the large cube rotates horizontally, the single color of its adjacent sides is destroyed, and the cube that forms a new pattern will rotate and change again, forming each side with blocks of different colors. The way to play is to restore the scrambled cube to a single color on all six sides as quickly as possible by rotating it.

[0003] In the Rubik's Cube competition, a more complex Rubik's Cube is usually used as a competition prop. During the competition, the contestants need to rotate it quickly in order to complete the reordering of the Rubik's Cube in the shortest time. The traditional Rubik's Cube relies on the player's precise rotation when rotating, and the Rubik's Cube needs to be rotated 90 degrees each time, so that the Rubik's Cube is not easy to get stuck. The Rubik's Cube with magnetic positioning blocks will have magnetic attraction to allow the Rubik's Cube to be magnetically adsorbed at 90 degrees, and the positioning is more accurate.

[0004] Some existing magnetic Rubik's Cubes have magnetic structures that are positioned on the top surface. Most of them are positioned through a positioning magnet in the middle of the corner block and the edge block. The magnetic force of the positioning magnets is relatively strong. The starting resistance of the Rubik's Cube from static to rotating is relatively large, which is not conducive to quickly restoring the Rubik's Cube, and it is difficult to change the size of the magnetic force of the block, thereby making it difficult to adjust the magnetic force of the layer where the block is located.
