Description

Changeable magnetic positioning structure magic cube with adjustable central shaft positioning magnetic force

Technical Field

The invention relates to the technical field of magic cubes, in particular to a magic cube with a changeable magnetic positioning structure and an adjustable central shaft positioning magnetic force.

Background

The traditional magic cube is a 6-face cube made of hard plastic with elasticity. The core is a shaft and consists of 26 squares. The 26 squares comprise 6 inner central blocks which are fixed and only one side of which is provided with color. The corner block has 8 rotatable. The prism blocks 12 can also rotate. The blocks are arranged so that each face of the cube has the same color when the toy is sold. When one face of the big cube is in translational rotation, the single color of the adjacent faces is destroyed to form a cube with a new pattern, and then the cube is changed to form a cube with each face composed of squares with different colors. The playing method is to restore the disordered cube to six faces in a single color as soon as possible by rotating.

Since the advent of the magic cube, the magic cube is popular and easy to understand and has high universal flexibility due to the strong intelligence-developing function for human beings, and the magic cube must be played by players with concentrated mind, continuous thinking and impatience, so that the magic cube becomes a toy for developing special intelligence and a toy for checking the intelligence level and maturity of the players, thereby attracting a batch of players.

In the magic cube competition, a more complex magic cube is usually adopted as a competition prop, and in the competition process, contestants need to rotate quickly to complete the reordering of the magic cube in the shortest time. Traditional magic cube relies on the accurate rotation of player when rotating, need make the magic cube rotate at every turn and all be 90 degrees, and the magic cube just is difficult to the card dead like this, and has the magic cube of magnetic force location square, has magnetic attraction and lets the magic cube be adsorbed by magnetic force at 90 degrees bodies, fixes a position more accurately.

However, the existing magnetic magic cube has the following defects:

(1) some of current have magnetic force magic cube, magic cube product magnetism structure of inhaling all is the top surface location, and the majority is respectively a location magnet through the middle of hornblock and arris piece, and location magnet magnetic force is all bigger, and the starting resistance that the magic cube got up from static to the rotation is bigger, is unfavorable for restoring the magic cube fast.

(2) Some existing magnetic magic cubes are provided with magnetic positioning devices, the magnetic positioning devices are usually magnets, one of the magnetic positioning devices is that the whole magic cube needs to be disassembled, and the magnets are adhered to the inner walls of the cubes through chemical substances such as glue, so that the glue is not environment-friendly, poor in assembly precision, not easy to replace the magnets, and difficult to change the magnetic force of the cubes, and therefore the magnetic force of the layers where the cubes are located is difficult to adjust.

(3) The existing magic cube center block in the market mostly adopts the elasticity of spring to compress tightly angle piece and arris piece, relies on adjusting the power size that comes the pivoted of elasticity, and the spring is with the center block contact, so frictional resistance is great, is unfavorable for improving pivoted speed. Some of current have magnetic force magic cube, adopt the mode of iron axle to adjust the elasticity dynamics, convenient and accurate not enough in the operation.

(4) Some of the existing magnetic magic cubes have a magnetic force magic cube, do not have a multistage exchange structure capable of shifting after magnetic exchange, and cannot effectively carry out full compatibility on multistage magnetic force.

(5) Some existing magic cubes with magnetic force are not convenient and inaccurate to adjust because no obvious reference exists for adjusting the magnetic force and the wheelbase of the magic cube in the market.
