Description

Technical Field

[0001] The utility model relates to the field of Rubik's cubes, and particularly relates to a corner block and a Rubik's cube. Background Art

[0002] A Rubik's cube generally includes corner blocks, edge blocks, center blocks and a center ball shaft. In existing Rubik's cubes, magnets are usually arranged on the corner blocks, edge blocks and the center shaft respectively, so that there is magnetic adsorption between the corner blocks and the edge blocks, and between the corner blocks and the center shaft. With the magnetic positioning during the rotation process, when the Rubik's cube is about to rotate into place, it will be magnetically adsorbed, causing the Rubik's cube to directly return to its position; thus, there will be no position error between the blocks, and further, the rotation actions of the player on the Rubik's cube will be more precise. In this way, the jamming of the Rubik's cube caused by inaccurate player techniques and non-standard actions is reduced, and the deformation of the Rubik's cube is also reduced, so as to achieve the effect of a compact and smooth Rubik's cube and improve the hand feeling.

[0003] However, existing Rubik's cubes still have the following defects:

[0004] (1) When adjusting the magnetism of the existing corner blocks, only the magnetic force between the corner block and the edge block can be adjusted individually, or only the magnetic force between the corner block and the shaft can be adjusted individually. The operation is very troublesome, bringing inconvenience to users and poor user experience.

[0005] (2) The magnetic rod on the existing corner block is fixedly connected to the corner block, and the magnetic rod with different magnetic forces cannot be replaced. When different people rotate the Rubik's cube, those with greater hand strength can easily rotate it, and there is a lack of damping during the rotation process, resulting in a poor user experience. Those with smaller hand strength need to use a lot of force to rotate it, which is very energy-consuming. Summary of the Invention

Detailed implementation manners

[0052] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail an angle block and a Rubik's Cube provided by the present utility model in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present utility model and be able to implement it. However, the examples given are not intended to limit the present utility model.

[0053] Embodiment 1

[0054] Please refer to Figures 1 to 12 As shown, this embodiment provides an angle block, including a housing 100, an adjustment component 200, a magnetic component 300, a connection seat 400, and a magnetic rod 500. The adjustment component 200 is rotatably arranged inside the housing 100. The magnetic component 300 is slidably arranged on the adjustment component 200. When the adjustment component 200 rotates, it simultaneously drives the magnetic component 300 to approach or move away from the inner side wall of the housing 100. The connection seat 400 is located at the lower end of the adjustment component 200 and is movably connected to the adjustment component 200. One end of the magnetic rod 500 is detachably arranged inside the connection seat 400, and the other end extends outside the housing 100. When the adjustment component 200 rotates, it simultaneously drives the connection seat 400 to move up or down, and drives the magnetic rod 500 to move up or down relative to the housing 100.

[0055] Due to the provision of the housing 100, the adjustment component 200, the magnetic component 300, the connection seat 400, and the magnetic rod 500, through the combined use of the adjustment component 200, the magnetic component 300, the connection seat 400, and the magnetic rod 500, rotating the adjustment component 200 can not only make the magnetic component 300 approach or move away from the inner side wall of the housing 100, but also enable the magnetic rod 500 to move up and down, thereby realizing the simultaneous adjustment of the positioning magnetic force strength between the angle block and the edge block and the adjustment of the magnetic force strength between the angle block and the axis. The operation is convenient and the use effect is good. It effectively solves the problem that in the existing angle blocks, when performing magnetic adjustment, only the positioning magnetic force strength between the angle block and the edge block can be adjusted separately, or only the magnetic force strength between the angle block and the axis can be adjusted separately. At the same time, by detachably arranging the magnetic rod 500 inside the connection seat 400, the disassembly and assembly of the magnetic rod 500 are more convenient, facilitating the replacement of the magnetic rod 500 with different magnetic forces to adapt to different usage scenarios, and effectively solving the problem that the magnetic rod 500 cannot be adaptively replaced.

By setting a certain slope for the card slot 232 in the direction away from the base 210, and making the end of the clamping post 420 of the connecting seat 400 be clamped at one end of the card slot 232 away from the base 210, when the adjustment disk 230 rotates around the central shaft body 220, the clamping post 420 of the connecting seat 400 can move up and down along the slope where one end of the card slot 232 away from the base 210 is located, thereby driving the magnetic bar 500 provided on the connecting seat 400 to move up and down, thereby realizing the adjustment of the magnetic force strength between the corner block and the shaft magnet. When there are two or more slopes, each slope rises or falls in the same direction (such as the clockwise direction or the counterclockwise direction). In addition, by providing an opening at one end of the guiding groove 211 located at the edge of the base 210, when the connecting member 330 is located at the opening, the magnetic block 310 can be closer to the inner wall of the housing 100.

[0060] In a preferred embodiment, the connecting base 400 includes a connecting base body 410, a clamping post 420, a clamping ring 430 and a positioning groove 440; the clamping post 420 is arranged on one side of the connecting base body 410 close to the base 210 and is located on both sides of the through hole of the connecting base body 410; one end of the clamping ring 430 is fixed to the side of the connecting base body 410 away from the base 210, and the other end extends to the side away from the connecting base body 410; the first end of the positioning groove 440 is located in the clamping ring 430 and is fixed to the connecting base body 410 and communicates with the through hole of the connecting base body 410; the second end of the positioning groove 440 extends out of the clamping ring 430 to the side away from the connecting base body 410, and two limiting blocks 441 extend radially on the inner surface of the second end of the positioning groove 440, and a certain distance is provided between the two limiting blocks 441 to form a limiting hole 442.

At the same time, the magnetic rod 500 can be clamped in the positioning groove 440 through the limiting hole 442, which is beneficial to the disassembly and assembly of the magnetic rod 500. Specifically, by setting the clamping post 420 in a T shape, after the clamping post 420 penetrates through the base 210 and the clamping groove 232, the end of the clamping post 420 can be clamped in the groove 232A on the clamping groove 232.
