DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0016] like Figure 1-3 A detachable rotating disk of a mahjong machine is shown, comprising a rotating disk body 1, a mounting hole 2 is opened in the middle of the rotating disk body 1, a plurality of patches 3 are attached to the surface of the rotating disk body 1, the rotating disk body 1 comprises an annular rotating disk ring 4 located on the outside and an upwardly bulging rotating disk inner ring 5 located on the inner side of the rotating disk ring 4, the mounting hole 2 is located at the top of the upwardly bulging rotating disk inner ring 5, the rotating disk ring 4 and the rotating disk inner ring 5 are detachable, a plurality of reinforcing ribs 6 are fixed to the bottom of the rotating disk ring 4, and the reinforcing ribs 6 extend inwardly to be attached to the bottom of the rotating disk inner ring 5;

[0017] Based on the above, the turntable body 1 is of split design, divided into a turntable ring 4 and a turntable inner ring 5. The turntable ring 4 and the turntable inner ring 5 are detachable, which is convenient for separate disassembly during maintenance.

[0018] Furthermore, the reinforcing ribs 6 at the bottom of the turntable ring 4 support the separated structure, ensuring that the separated structure has better stability and structural strength.

[0019] A plurality of first through holes 7 are evenly formed on the inner ring 5 of the turntable, and a plurality of second through holes 8 are evenly formed on the turntable ring 4. The edge of the turntable ring 4 extends upward to form a rib 9, and a gear ring 10 is installed on the outer wall of the rib 9.

[0020] On the basis of the above, the rib 9 is used to cover the mahjong during the cleaning process, so that the mahjong part located on the turntable body 1 inside the rib 9 can be turned over for cleaning. At the same time, a motor is installed inside the mahjong machine, which engages with the gear ring 10 on the outer wall of the rib 9 to drive the entire turntable body 1 to rotate inside the mahjong machine.

[0021] A plurality of inwardly recessed limiting grooves 11 are provided at the inner edge of the turntable ring 4, and a plurality of limiting protrusions 12 cooperating with the limiting grooves 11 are installed at the outer edge of the turntable inner ring 5;

[0022] The turntable ring 4 and the turntable inner ring 5 are designed to be separated. When the two are assembled together, multiple limiting protrusions 12 and limiting grooves 11 cooperate with each other to ensure the stability of the angle between the two, thereby avoiding separation and deviation of the turntable body 1 during rotation.

[0023] A support ring 13 is installed at the bottom end of the retaining edge 9, and a plurality of rotating balls 14 are embedded at the bottom of the support ring 13;

[0024] Based on the above, the support ring 13 is used to support the turntable body 1, so that a gap is separated between the turntable body 1 and the inner cavity of the mahjong machine, and the reinforcing rib 6 is located in the gap. The support ring 13 avoids the conflict between the reinforcing rib 6 and the internal structure of the mahjong machine, and a plurality of balls 14 are installed at the bottom of the support ring 13. During the rotation of the turntable body 1, the support ring 13 is supported by the rotation of the balls 14 to ensure the smoothness of its rotation.

[0025] Gaps are left between several patches 3, and limiting strips 15 are provided at the ends of the gaps. The limiting strips 15 are fixed on the surface of the turntable ring 4, and the patches 3 are pasted on the surface of the turntable body 1. The limiting strips 15 limit and fix the positions of the patches 3. The patches 3 are specifically made of velvet material with a thickness of 1-2mm. When the mahjong is flipped, the patches 3 can reduce the noise of the flipping of the mahjong, and at the same time reduce the damage to the mahjong and the surface of the turntable body 1.

[0026] A limiting column 16 is fixed on the reinforcing rib 6 at the bottom of the inner ring 5 of the turntable, and a limiting hole 17 cooperating with the limiting column 16 is opened on the inner ring 5 of the turntable;

[0027] On the basis of the above, the turntable inner ring 5 is separable from the turntable ring 4. The turntable inner ring 5 can be separated and removed by lifting it upwards. When the turntable inner ring 5 is installed on the turntable ring 4, the limiting protrusion 12 and the limiting groove 11 are aligned, and the turntable inner ring 5 is placed on a plurality of reinforcing ribs 6, so that the limiting holes 17 on the turntable inner ring 5 face the limiting columns 16 and are put on, so that a plurality of limiting columns 16 are inserted into the limiting holes 17, and the limiting grooves 11 and the limiting protrusions 12 cooperate to fix the angle between the turntable inner ring 5 and the turntable ring 4 to ensure the stability of the two after installation. The separate design structure makes it easy to disassemble the turntable body 1, and the reinforcing ribs 6, the limiting protrusions 12 and the limiting columns 16 are used to cooperate to make the various components firmly connected. The overall structure is stable and will not shake during shuffling, and the rotation process is smooth.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
