Description

Technical Field

[0001] This utility model relates to the field of Rubik's Cube technology, and more specifically, it relates to a Rubik's Cube with adjustable elasticity and axis spacing, and a Rubik's Cube. Background Technology

[0002] As the Rubik's Cube game has evolved, its performance has also improved. The earliest Rubik's Cubes were all non-adjustable rivet designs. Later, with the development of technology, adjustable Rubik's Cubes with a combination of screws and springs gradually appeared on the market.

[0003] There are two main ways to adjust a Rubik's Cube: directly turning the screws to adjust both the axis distance and the spring force simultaneously; and adjusting the spring force component to adjust the spring force.

[0004] However, directly turning the screws cannot adjust the spring tension without adjusting the axis distance, thus failing to meet the fine-tuning requirements of players. Furthermore, adjusting by turning the screws cannot provide specific data-driven adjustments to the cube's spring tension and axis distance.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a Rubik's Cube with an adjustable elasticity and axis spacing structure and a Rubik's Cube.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A Rubik's Cube with adjustable elasticity and axis spacing, characterized in that it includes a center cover and a center piece.

[0009] It also includes a central shaft, on which screws are fixedly connected, and the screws are movably connected to the central block.

[0010] The cavity formed by the center cover and the center block also includes a wheelbase adjustment disc, a wheelbase fixing disc, a spring, and a spring adjustment component.

[0011] Preferably, the central block is provided with elastic adjustment ratchet, fixing teeth and screw holes.

[0012] Preferably, the screw is provided with a wheelbase indicator pointer.

[0013] Preferably, the wheelbase adjustment disc is provided with a wheelbase indicator, a one-way connecting tooth, a spring indicator window, and a one-way ratchet for wheelbase adjustment.

[0014] Preferably, the wheelbase fixing plate is provided with wheelbase adjustment and alignment ratchet teeth and locking grooves.

[0015] Preferably, the elastic adjustment component is provided with an adjustment arm, a connecting tooth, an elasticity indicator, and an elasticity adjustment ratchet.

[0016] Preferably, the retaining groove is movably connected to the retaining tooth.

[0017] Preferably, the elastic adjustment ratchet is movably connected to the elastic adjustment alignment ratchet. When the adjustment arm is turned clockwise, the wheelbase adjustment disc is locked by the wheelbase adjustment one-way ratchet, allowing only the elastic adjustment component to rotate. The elastic force reading displayed on the elastic force indicator window changes accordingly.

[0018] Preferably, the wheelbase adjustment unidirectional ratchet is movably connected to the wheelbase adjustment alignment ratchet. Rotating the adjustment arm counterclockwise rotates the wheelbase adjustment dial, completing the wheelbase adjustment. The wheelbase indicator pointer changes accordingly.

[0019] Preferably, the unidirectional connecting tooth is movably connected to the connecting concave tooth. When the adjusting arm is turned counterclockwise, the connecting concave tooth drives the unidirectional connecting tooth to rotate together.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this utility model, the design of unidirectional connecting teeth and connecting concave teeth enables the joint adjustment of the wheelbase adjustment disc and the elastic adjustment component, avoiding the drawback of the wheelbase not being able to be adjusted independently in the traditional design.

[0022] 2. In this utility model, the locking effect of the wheelbase adjustment disc when the adjustment arm is turned clockwise is achieved by the movable connection between the locking groove and the fixed locking tooth and the unidirectional locking of the wheelbase adjustment unidirectional ratchet and the wheelbase adjustment alignment ratchet, thereby adjusting the elastic force independently.

[0023] 3. In this utility model, the Rubik's Cube can be adjusted by hand by setting up an adjustment arm. The design of the elastic force reading and the axis distance reading quantifies the adjustment indicators, which facilitates the control and standardization of product quality in the production process. Moreover, the elastic force can be adjusted by rotating clockwise and the axis distance can be adjusted by rotating counterclockwise, simplifying the adjustment logic. Attached Figure Description

[0034] Reference Figures 1 to 9 .

[0035] Example 1 further illustrates the Rubik's Cube elasticity and axis adjustable structure and Rubik's Cube proposed in this utility model.

[0036] like Figure 1 As shown, it includes a central cover 1 and a central block 2.

[0037] It also includes a central shaft 3, on which a screw 4 is fixedly connected, and the screw 4 is movably connected to the center block 2. A wheelbase indicator pointer 41 is provided on the screw 4.

[0038] like Figure 2As shown, the cavity formed by the center cover 1 and the center block 2 also includes a wheelbase adjustment disc 5, a wheelbase fixing disc 6, a spring 7, and a spring force adjustment component 8.

[0039] like Figure 3 As shown, the center block 2 is provided with a spring-loaded adjusting ratchet 21, a fixing tooth 22, and a screw hole 23. The center block 2 is located at the center of one side inside the cube, where the adjusting ratchet 21 and screw hole 23 are located. Both the screw hole 23 and the adjusting ratchet 21 are cylindrical structures, and they are placed coaxially. The fixing tooth 22 is located on the outer side of the cylindrical screw hole 23. The center block 2, adjusting ratchet 21, fixing tooth 22, and screw hole 23 are integrally formed during injection molding. The screw 4 is installed in the screw hole 23.

[0040] like Figure 2 and Figure 4 As shown, the wheelbase adjustment disc 5 is provided with a wheelbase indicator 51, a one-way connecting tooth 52, a spring indicator window 53, and a one-way wheelbase adjustment ratchet 54.

[0041] like Figure 2 As shown, the wheelbase indicator 51 is located on the outer side of the wheelbase adjustment disc 5, and as... Figure 4 As shown, the one-way connecting tooth 52 is fixed on the side away from the wheelbase indicator 51, and the wheelbase adjustment one-way ratchet 54 is fixedly installed on this side. The one-way connecting tooth 52 is arranged in a ring array with the axis of the wheelbase adjustment one-way ratchet 54. The elastic indicator window 53 is opened on the side wall of the wheelbase adjustment disk 5. In this embodiment, the wheelbase adjustment disk 5, the wheelbase indicator 51, the one-way connecting tooth 52, and the wheelbase adjustment one-way ratchet 54 are integrally formed during injection molding.

[0042] The wheelbase fixing disc 6 is provided with a wheelbase adjustment and alignment ratchet 61, and has a locking groove 62. For example... Figure 5 As shown, the wheelbase fixing plate 6 has a cylindrical structure. The side wall of the wheelbase fixing plate 6 is provided with an axially arranged tooth fixing groove 62. The wheelbase fixing plate 6 is fixedly installed with a wheelbase adjustment and alignment ratchet 61 at one end near the wheelbase adjustment plate 5. The wheelbase adjustment and alignment ratchet 61 and the wheelbase fixing plate 6 are integrally formed during injection molding.

[0043] like Figure 6 As shown, the locking tooth fixing groove 62 is movably connected to the fixing tooth 22, and the locking tooth fixing groove 62 can only move up and down under the fixing of the fixing tooth 22.

[0044] like Figure 7As shown, the wheelbase adjustment unidirectional ratchet 54 is movably connected to the wheelbase adjustment alignment ratchet 61. Since the wheelbase fixing disk 6 is movably connected to the fixing tooth 22 through the tooth fixing groove 62, and the wheelbase adjustment disk 5 is movably connected to the wheelbase adjustment alignment ratchet 61 through the wheelbase adjustment unidirectional ratchet 54, the wheelbase adjustment disk 5 can only rotate counterclockwise in one direction.

[0045] The elastic adjustment component 8 is provided with an adjustment arm 81, a connecting tooth 82, an elastic force indicator 83, and an elastic force adjustment ratchet 84. The specific configuration is as follows: Figure 2 and Figure 8 As shown, the elastic adjustment component 8 is a "T"-shaped cylindrical structure. Two symmetrically arranged adjustment arms 81 are fixedly installed at the top edge of the cylindrical structure. A connecting groove 82 is provided on the top of the inner side wall of the cylindrical structure. The elastic force indicator 83 is located at the top of the elastic adjustment component 8, and the elastic adjustment ratchet 84 is located at the bottom of the cylindrical structure. In this embodiment, the elastic adjustment component 8, adjustment arms 81, connecting groove 82, elastic force indicator 83, and elastic adjustment ratchet 84 are integrally formed during injection molding.

[0046] like Figure 8 As shown, the one-way connecting tooth 52 is movably connected to the connecting concave tooth 82. When the adjusting arm 81 is turned counterclockwise, it drives the elastic adjusting member 8 to rotate, which in turn drives the one-way connecting tooth 52 to rotate together through the connecting concave tooth 82. The wheelbase adjusting disk 5 and the elastic adjusting member rotate together by the same angle. Through the action of the wheelbase adjusting one-way ratchet 51 and the wheelbase adjusting alignment ratchet 61, the wheelbase fixing member and the elastic adjusting disk descend one ratchet increment together. This allows the wheelbase to be changed without changing the spring force.

[0047] like Figure 9 As shown, the spring adjustment ratchet 84 is movably connected to the spring adjustment alignment ratchet 21. When the adjustment arm is turned clockwise, the adjustment arm drives the spring adjustment component to rotate. The wheelbase fixing disk 5 is locked to the fixing tooth 22 through the locking groove 62, thereby locking the wheelbase adjustment disk 5 through the wheelbase adjustment one-way ratchet 51. When the adjustment arm 81 is turned clockwise, only the spring adjustment component can rotate. The change in the spring force indicated by the spring force display window 53 allows for independent adjustment of the spring force without changing the wheelbase.

[0048] It should be noted that the Rubik's Cube debugging structure of this application can be used for different types of Rubik's Cubes, including but not limited to 3x3, 2x2, 4x4, and 5x5 Rubik's Cubes.

[0049] Example 2

[0050] The following technical features are added based on Embodiment 1:

[0051] The elastic adjustment disc is equipped with a pull ring, which facilitates adjustment by pulling the ring to drive the adjustment arm (not shown). The spring is replaced by two mutually repelling magnetic rings, which replace the spring to form a repulsive force (not shown). This Rubik's Cube can be a 3x3, 2x2, 4x4, 5x5, or other Rubik's Cubes with a center piece and a central axis structure.

[0052] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
