Description

Magic cube

Technical Field

The utility model relates to the technical field of educational toys, in particular to a magic cube.

Background

The central block of the cube requires an inward force to secure the faces of the cube. Traditional magic cubes use screws and springs to provide inward force to the center block. After that, there are different fixing and positioning modes for providing elastic force, such as no screws, and fixing the magic cube by using a part with a fixed point and a certain length of middle shaft combined with the fixed part. Such as no longer using springs, using magnets, the repulsive force of which is used to provide the inward force. The prior combination mode has larger friction with the fixed position of the middle block and the middle shaft when the magic cube rotates. The magic cube has larger rotating resistance under the stress condition and poor operation hand feeling.

In view of this, the present utility model has been made.

Referring to fig. 1 to 3, an embodiment of the present application provides a magic cube, including: the device comprises an axle center assembly 1, an accelerating piece 3, a plurality of center shafts 2 and a plurality of blocks 4. Each center shaft 2 is connected to the center shaft assembly 1, a cap 21 is arranged at one end, away from the center shaft assembly 1, of each center shaft 2, each block 4 is arranged on the circumferential side of the center shaft assembly 1, at least part of blocks 4 are rotatably connected to the corresponding center shaft 2, the accelerating member 3 comprises a main body member 31 and a plurality of rolling bodies, the main body member 31 is sleeved between the block 4 on the center shaft 2 and the cap 21 of the center shaft 2, each rolling body is movably arranged on the main body member 31, each rolling body is sequentially arranged along the circumferential direction of the center shaft 2, and the rolling bodies are respectively in direct or indirect contact with the cap 21 and the block 4.

The body member 31 may be annular, rolling elements may be disposed on the body member 31, and the mating relationship of the rolling elements and the body member 31 may be similar to the mating relationship of a cage and balls in a conventional bearing.

According to the magic cube provided by the embodiment of the application, the rolling bodies are arranged between the cap body 21 and the block body 4, so that the rotation resistance of the block body 4 relative to the center shaft 2 is reduced, the magic cube rotates more smoothly, and the hand feeling is better.

In some possible embodiments, the accelerator 3 comprises a first rotating ring 33, said first rotating ring 33 being sheathed on said central shaft 2, and said first rotating ring 33 being located between the rolling bodies and the cap 21. The rolling bodies directly contact the first rotating ring 33. The first rotating ring 33 can be in direct contact with the cap body 21, and the rolling bodies are in direct contact with the first rotating ring 33, so that sliding friction is converted into rolling friction, and friction resistance is greatly reduced.

In some possible embodiments, the acceleration member 3 includes a second rotating ring 34, the second rotating ring 34 is sleeved on the bottom bracket 2, the second rotating ring 34 is located between the rolling body and the block 4, and the second rotating ring 34 directly or indirectly contacts the block 4, and the rolling body directly contacts the second rotating ring 34.

Taking indirect contact between the block 4 and the second rotating ring 34 as an example, the magic cube comprises a spring 5, the spring 5 is sleeved on the central shaft 2, and two ends of the spring 5 respectively prop against the block 4 and the second rotating ring 34. I.e. the second rotating ring 34 and the block 4 are indirectly in contact by means of the spring 5. The spring 5 directly abuts against the second rotating ring 34.

The annular surfaces of the opposite sides of the first rotating ring 33 and the second rotating ring 34 are flat surfaces, and the spring 5 abuts against the flat surface of the second rotating ring 34. The spring 5 is not easily caught on the second rotating ring 34, and even if the spring 5 is caught on the second rotating ring 34, since the first rotating ring 33 and the second rotating ring 34 are rotatably fitted, the frictional resistance is not excessively large, and the spring 5 is not severely deformed.

Because the spring 5 abuts against the second rotating ring 34, the second rotating ring 34 is kept against the rolling bodies, the rolling bodies abut against the first rotating ring 33, and the first rotating ring 33 abuts against the cap 21.

In some possible embodiments, the first rotating ring 33 and the second rotating ring 34 are both rotatably engaged with the bottom bracket 2 and the first rotating ring 33 and the second rotating ring 34 are both slidable relative to the bottom bracket 2 along the length of the bottom bracket 2.

In this embodiment, the inner diameters of the first rotating ring 33, the second rotating ring 34 and the main body member 31 are slightly larger than the central shaft 2, so that the first rotating ring 33, the second rotating ring 34 and the main body member 31 are conveniently and smoothly sleeved on the central shaft 2, and the assembly difficulty is reduced.

In some possible embodiments, the block 4 connected to the bottom bracket 2 is provided with a groove 41, the bottom wall of the groove 41 is provided with a through hole for the bottom bracket 2 to pass through, and the accelerator 3 is at least partially embedded in the groove 41.

The provision of the groove 41 facilitates the accommodation of the second rotating ring 34, the main body member 31 and at least part of the first rotating ring 33 of the accelerator member 3 within the groove 41, providing a mounting space for the accelerator member 3. An inner supporting step can be arranged on the inner wall of the through hole, and one end of the spring 5 can be propped against the inner supporting step. The spring 5 may also directly abut against the bottom wall of the recess 41.

In the prior art, a gap is formed between the block 4 and the screw, the block 4 does not move vertically, and the block 4 is also displaced laterally, i.e. moves in the cross section of the screw. The application can control the lateral movement and deflection amplitude of the block 4 by arranging the groove 41 and adding the accelerating piece 3.

Illustratively, the outer diameter of the accelerating member 3 is matched with the inner diameter of the groove 41, the inner diameter of the accelerating member 3 is smaller than the inner diameter of the through hole, the outer diameter of the accelerating member 3 may be understood as the outer diameters of the main body member 31, the first rotating ring 33 and the second rotating ring 34, and the inner diameter of the accelerating member 3 may be understood as the inner diameters of the main body member 31, the first rotating ring 33 and the second rotating ring 34. Because the accelerating piece 3 has small inner diameter, the accelerating piece can be limited by the middle shaft 2, and the transverse movement and deflection amplitude of the block 4 are reduced.

In some possible embodiments, the acceleration member 3 is a planar bearing. The upper ring of the planar bearing of the accelerator 3 is the first rotating ring 33 above and the lower ring is the second rotating ring 34. The body member 31 may be a cage of a planar bearing, and the rolling bodies may be balls provided on the cage.

In some possible embodiments, the cube is a positive-order cube or a shaped cube.

For example, when the cube is a positive cube, the cube may be first order second order third order … … nine and eleven orders. When the cube is a positive-order cube, the block 4 of the cube connected to the central shaft 2 can be understood as the center block of the cube.

When the magic cube is a special-shaped magic cube, the magic cube can be any one of a mirror surface magic cube, a three-order five-magic cube and a pyramid magic cube.
