[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0031] One type of mahjong machine in this embodiment, such as Figure 1 As shown, the system includes a tabletop 20 and a dice rotating device 10 disposed at the center of the tabletop 20. The structure of the dice rotating device 10 is as follows: Figure 2 , Figure 3 As shown, it includes a dice cavity for holding dice, a cover 15 made of transparent material disposed on the top of the dice cavity 11, and a rotating disk 12 disposed on the bottom of the dice cavity. A drive motor 14 is disposed below the rotating disk 12 for driving the rotating disk 12 to rotate.
[0032] As an improvement in this embodiment, the upper surface of the rotating disk 12 is made of a rigid material, such as plastic, eliminating the need for the felt layer commonly used in the prior art. In the absence of a felt layer, to increase the friction between the rotating disk and the dice, this embodiment provides a damping structure on the upper surface of the rotating disk 12. When the rotating disk rotates, the damping structure drives the dice to move randomly.
[0033] The damping structure in this embodiment includes, but is not limited to, the following: a groove provided on the upper surface of the rotating disk 12; or, as... Figure 4 As shown, a slot 121 penetrates the rotating disk; or, as... Figure 5 As shown, a protrusion 122 is provided on the upper surface of the rotating disk; or, an uneven structure is provided on the upper surface of the rotating disk.
[0034] As preferred, the upper surface of the rotating disc 12 is provided with at least two damping structures in the circumferential direction. As shown in FIG. 1, the first embodiment of the present application has three damping structures in the circumferential direction. Figure 4 As shown in FIG. 1, the damping structure includes three grooves 121 arranged in the circumferential direction. The advantage of the grooves is that the debris generated by friction can leak out of the grooves. Figure 5 As shown in FIG. 1, the damping structure includes three protrusions 122 arranged in the circumferential direction. It should be noted that the above different damping structures can be combined when the number of damping structures is at least two.
[0035] In the present embodiment, during the rotation of the rotating disc 12, the dice move towards the inner wall of the dice cavity 11 under the action of centrifugal force. In order to increase the randomness of the irregular movement of the dice, a blocking structure 13 protruding from the surface of the inner wall of the dice cavity 11 can be provided. When the dice collide with the blocking structure 13 during movement, the trajectory of the dice will change. The specific shape of the blocking structure 13 is not limited in the present embodiment.
[0036] As preferred, at least two blocking structures can be arranged in the circumferential direction on the inner wall of the dice cavity 11, further improving the randomness of the irregular movement of the dice.
[0037] As preferred, as shown in FIG. 1, Figure 2 Figure 3 As shown in FIG. 1, the dice cavity includes a first tapered section A, a transition section B, and a second tapered section C from bottom to top, wherein the taper of the transition section B is smaller than the taper of the first tapered section A and the second tapered section C.
[0038] As preferred, the height of the second tapered section C is greater than the sum of the height of the transition section B and the height of the first tapered section A, and the height of the first tapered section A is greater than the height of the transition section B. After such arrangement, the dice easily roll over during movement through the taper changes of the first tapered section A, the transition section B, and the second tapered section C, thereby increasing the randomness of the movement of the dice.
[0039] As preferred, in the present embodiment, the blocking structure 13 is arranged on the first tapered section A and the transition section B. In this way, the dice have a greater chance of contacting the blocking structure 13 during movement. Of course, the blocking structure 13 can also be arranged only on the first tapered section A or the transition section B.
[0040] In summary, the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
