A Rubik's Cube with an integrally formed axis and pre-assembled elastic components

Abstract

The invention discloses a magic cube with an integrally-formed central spindle and a preassembled elastic component. The magic cube comprises the central spindle, a connecting rod, a central block and a spring; one end of the connecting rod and the central spindle are integrally formed, and the end, integrally formed with the central spindle of the connecting rod is provided with an extending part and an inserting connecting part; the other end of the connecting rod is provided with a penetrating connecting part; a nut and a spring sleeve are arranged in the central block, the nut is connected to the end, far away from the central spindle, of the penetrating connecting part, the spring sleeve is located on the side, close to the central spindle of the nut, and the end, close to the central spindle, of the spring sleeve is provided with an abutting connecting part; the nut is provided with a first limiting part, the spring sleeve is provided with a second limiting part, and the second limiting part is used for being matched with the first limiting part to limit the spring sleeve from moving towards the direction of being close to the central spindle; the spring is clamped between the nut and the spring sleeve. According to the magic cube, by improving the central spindle precision and the coaxiality of the central spindle with the central block, the frictional force and the elastic force of all the faces of the magic cube are more uniform; in addition, friction between the spring and the nut and the spring sleeve is reduced in the rotating process.

Description

technical field [0001] The invention relates to the technical field of Rubik's Cube, in particular to a Rubik's Cube with an integrally formed axis and pre-assembled elastic components. Background technique [0002] The existing Rubik's Cube is composed of multiple unit blocks and multi-dimensional connecting shafts. Taking the traditional third-order Rubik's Cube as an example, its main body is a cube structure, including 26 small squares and a three-dimensional connecting shaft. The small squares include six A central block located at the center of each face of the Rubik's Cube, eight corner blocks located at the end corners of the Rubik's Cube, and twelve edge blocks respectively located between adjacent two corner blocks, so that each face of the Rubik's Cube is nine Each layer of the Rubik's Cube can rotate freely based on the rotation characteristics of the three-dimensional shaft. When assembling the Rubik's Cube, connect the six central blocks to the ends of the thr...

Problems solved by technology

However, when the spring is arranged in the center block, the end of the spring close to the shaft core is generally abutted against the inner wall of the center block, so the center block generally has a tendency to move towards the direction of the shaft core under the action of the elastic stress of the spring. The trend makes it often necessary to push the center block when installing other corner blocks between the center block and the shaft core, so that other blocks can be installed normally, which is inconvenient to assemble and affects the assembly speed of the Rubik's Cube; and during the rotation of the Rubik's Cube, the spring will Friction with the nut, or with the center block, it is necessary to place a spacer between them to reduce the friction, but even so, it is impossible to avoid the metal friction sound produced by the spring end and the spacer, and the spring will be in contact with the assembled Rubik's Cube when it is turned. Other parts rotate and rub against each other, making a sound of spring friction, which affects the durability of the spring

[0004] In addition, in the existing structure, the center blocks corresponding to different faces on the shaft core need to be connected by a connecting rod, and the connecting rods on different faces need to be installed through different processes, which is difficult to assemble, and each side of the shaft core It is difficult for the central block on the corresponding connecting rod to have a consistent coaxiality with the shaft core, which will also greatly affect the rotation characteristics of the Rubik's Cube
