[0002] The statements in this section are merely background information relating to this disclosure, and these statements may constitute prior art. In the process of developing this utility model, the inventors discovered at least the following problems in the prior art.

[0003] Mahjong is a popular form of entertainment, frequently used in leisure activities, especially in card and board game rooms. However, due to regional differences, the rules of mahjong vary from place to place. People in Southwest China mostly prefer Sichuan mahjong. Sichuan mahjong has a unique feature: "determined suit." This means that before each round, each player must choose a suit as their "missing suit." During the game, tiles of that suit are guaranteed to be played, and the winning hand cannot contain tiles of that suit.

[0004] Currently, players usually remember the missing pieces set by each other, which sometimes leads to forgetting and is very inconvenient. Summary of the Invention

[0005] In view of the above problems, the purpose of this utility model is to solve some of the problems in the prior art, or at least alleviate these problems.

[0006] A mahjong set-piece center plate includes a center plate surface and a control mechanism; the center plate surface is provided with a dice plate and a lifting button connected to the control mechanism; the control mechanism includes a circuit control board located below the bottom surface of the center plate surface, for connecting to the mahjong machine host, and controlling the mahjong machine host after receiving a click of the lifting button; the center plate surface is also provided with four set-piece slots for placing a single mahjong tile; the four set-piece slots are located on the outer edge of the dice plate surface and are respectively used to correspond to the directions of the four players.

[0007] Furthermore, the fixed grid is equipped with a dice board button; the bottom of the dice board button is equipped with a trigger key, the trigger point of which is located at the corresponding position of the circuit control board, and the operation of the dice board can be controlled by touching the circuit control board through the trigger key.

[0025] The present invention will be further described below with reference to the accompanying drawings. The embodiments of the present invention are only used to illustrate the present invention and not to limit the present invention. Various substitutions and modifications made in accordance with ordinary technical knowledge and conventional means in the art without departing from the technical concept of the present invention should be included within the scope of the present invention.

[0026] To address the issue of players easily misremembering missing suits, the applicant improved the original center plate of the mahjong machine.

[0027] like Figure 1 As shown, a mahjong set-piece center plate includes a center plate surface 1 and a control mechanism; the center plate surface 1 is provided with a dice plate 3 and a lifting button 4 connected to the control mechanism; the control mechanism includes a circuit control board 7 located below the bottom surface of the center plate surface 1, which is used to connect to the mahjong machine host and control the mahjong machine host after receiving a click of the lifting button 4; the center plate surface 1 is also provided with four set-piece slots 2 for placing a single mahjong tile; the four set-piece slots 2 are located on the outer edge of the dice plate 3 and are respectively used to correspond to the directions of the four players.

[0028] The four designated slots (2) are open at the top and are used to hold a single mahjong tile. Since each of the four designated slots (2) corresponds to one of the four players' positions, during a game, players simply place the tile representing their missing suit into their designated slot (2), making it easy to identify each player's missing suit. Furthermore, because the designated slots (2) are designed around the perimeter of the dice plate (3), they do not obstruct the dice, making it easy for players to see the dice rolls. Being located relatively centrally within the center of the plate, they are also less affected by other players' moves, improving the smoothness of the game.

[0029] like Figure 1 As shown in Figures 2 or 4, the fixed-position grid 2 is equipped with a dice disc button 5; the bottom of the dice disc button 5 is equipped with a trigger key 12, the trigger point of which is located at the corresponding position on the circuit control board 7, such as... Figure 2 As shown, the operation of the dice disk 3 can be controlled by touching the circuit control board 7 through the trigger point of the trigger key 12, thereby realizing the dice shaking operation.

[0030] The dice disc button 5 can be located on the bottom inner side of the fixed suit grid 2, with its trigger button 12 located between the central plate 1 and the circuit control board 7. Players only need to press the dice disc button 5 to roll the dice. When playing a tile, since rolling the dice is not required, placing a tile with a missing suit on the dice disc button 5 will not affect the game. If the dice disc button 5 is not designed in conjunction with the fixed suit grid 2, since the fixed suit grid 2 occupies all four sides, the dice disc button 5 can only be designed in an empty position on the central plate 1. Due to the limited space on the central plate 1, the dice disc button 5 can only be placed at an angle, which not only occupies the space of the lifting button 4 but also easily leads to confusion with it, causing misoperations such as the central plate rising, significantly impacting the smoothness of the game. Therefore, through long-term practice, the applicant has found that combining the dice disc button 5 with the fixed suit grid 2 avoids the above-mentioned defects, not only making reasonable use of the central plate space but also ensuring the smoothness of the game, achieving multiple benefits.

[0031] Of course, the dice disc button 5 can also be connected to the circuit control board 7 via a wire, and the dice can be directly triggered by clicking. The dice disc button 5 using the above method does not need to be set on the bottom inside the fixed slot 2, but can be set on the inner or outer wall of the fixed slot 2, which can avoid accidental triggering of the dice shaking when mahjong tiles are placed in.

[0032] The fixed slot 2 can be set on the center plate 1 in various ways.

[0033] In Embodiment 1, the fixed-gap grid 2 is located on the top surface of the central plate 1 and connected to the central plate 1. The central plate 1 has a corresponding through hole at the dice disc button 5 of the fixed-gap grid 2, and the bottom of the dice disc button 5 passes through the through hole. At this time, the upper end of the dice disc button 5 is located inside the through hole of the fixed-gap grid 2, and the lower end passes through the through hole of the central plate 1. The trigger button 12 is located at the lower end of the fixed-gap grid 2, so that the trigger button 12 is located below the central plate 1, so that when the player clicks the dice disc button 5, the trigger button 12 contacts the circuit control board 7 to realize the dice rolling operation. Furthermore, since the dice disc button 5 is located inside the fixed-gap grid 2, even if the force is strong when playing a tile, it will be blocked by the fixed-gap grid 2, making it less likely to accidentally touch the dice disc button 5. This effectively avoids the defect of some current mahjong fixed-gap boxes, where the dice disc button 5 is accidentally touched when the mahjong tile is hit hard.

[0034] The dice disc button 5 can be made to contact the circuit control board 7 in several ways when clicked by the player. For example, in embodiment 1, the dice disc button 5 is hinged to the bottom surface of the central disc 1 via a button shaft 9. Figure 2As shown in Figure 4, a torsion spring can be installed on the button shaft 9. When the player clicks the upper end of the dice disc button 5, the trigger key 12 will rotate around the button shaft 9, thus contacting the circuit control board 7 to shake the dice. When the player releases the dice disc button 5, the torsion spring causes the trigger key 12 to return to its original position, thus disengaging from the circuit control board 7.

[0035] Of course, a return spring or similar method can also be used to control the up-and-down movement of the trigger button 12 to achieve the dice rolling. The above-mentioned implementation methods for the dice disc button 5 are all relatively common.

[0036] Since the fixed slot 2 in Embodiment 1 is located above the central disk 1, to prevent it from shifting due to impact during play, the fixed slot 2 in this application is fixedly connected to the central disk 1, or is designed as an integral part. For example, a positioning pin is provided below the fixed slot 2, which matches a corresponding pin hole on the top surface of the central disk 1, thereby achieving a detachable connection between the fixed slot 2 and the central disk 1. Compared to an integral design, the detachable connection of the fixed slot 2 makes it easier to clean the central disk. It also facilitates the replacement of the fixed slot 2.

[0037] Of course, the fixed slot 2 can also be embedded in the central disk 1 instead of being located above it. In embodiment 2, the central disk 1 has a through slot at the corresponding position of the fixed slot 2, and the fixed slot 2 is embedded in the central disk 1 through the through slot, so that the lower end of the fixed slot 2 passes through the central disk 1. When using this method, since the dice button is already located below the central disk 1, the dice button 5 is hinged to the bottom surface of the fixed slot 2 through the button shaft 9, thus realizing the dice shaking operation.

[0038] While the above solution makes the mahjong table appear flatter, the missing suit mahjong tiles are placed in the missing suit compartment 2, which is embedded in the central panel 1. When there are many mahjong tiles on the table, they can easily obscure the tiles in compartment 2, making it difficult for players to identify and affecting the flow of the game. Therefore, the upper surface of compartment 2 is higher than the top surface of the central panel 1. This slightly elevated compartment 2 can block other mahjong tiles from obscuring the missing suit tiles, allowing players to better identify the missing suit and ensuring a smoother game.

[0039] In addition, the height of the fixed gap 2 can be adjusted to be smaller than the height of the mahjong tile, so that part of the fixed gap mahjong tile is exposed on the table surface. It will not be blocked by other mahjong tiles, and the restriction of the fixed gap 2 can also prevent the fixed gap mahjong tile from shifting due to the impact of other mahjong tiles.

[0040] In Example 2, the fixed slot 2 can be fixedly connected to the through groove of the central plate 1 by means of welding, bonding or other methods, or the upper end of the fixed slot 2 can be wider than the through groove, so that it overlaps inside it.

[0041] Because the central disk is small, after adding the fixed slot 2, the usable space is very limited. Therefore, the display screen 6, used to display shuffling data, can only be placed at the edge near the central disk surface 1, resulting in the circuit control board 7 not being able to connect properly to the bottom of the display screen 6. Therefore... Figure 1 As shown in Figure 2, the central panel 1 is further provided with a display screen 6; the display screen 6 is located on the side of the fixed slot 2; the circuit control board 7 is provided with an extension plate 8 extending below the display screen 6, so as to connect the display screen 6 and the circuit control board 7 through the extension plate 8. By adding the extension plate 8 to the circuit control board 7, the circuit control board 7 extends to the bottom of the display screen 6 and connects with it, without affecting the normal operation of other components.

[0042] In Embodiment 1, the four fixed slots 2 can be individually fixed to the central panel 1. However, if a player plays a card with great force, the connection between a single fixed slot 2 and the central panel 1, such as the positioning pin, may be damaged or even broken, causing it to detach from the central panel 1. Therefore, it is preferable that the four fixed slots 2 are integrated and connected together, such as... Figure 1 As shown. When a single fixed slot 2 is subjected to a strong impact, the impact force can be transferred to the other three fixed slots 2, and the impact force is shared by the four fixed slots 2, which can effectively reduce the risk of damage to the fixed slot 2 and extend its service life.

[0043] Because the dice button 5 is located on the inner bottom surface of the fixed-piece square, and a fixed-piece mahjong tile is placed on top of it, there is still a possibility of accidentally activating the dice button 5 when placing the mahjong tile or when the tile is forcefully struck by another mahjong tile, leading to an unintended dice roll. To avoid this problem, after the dice button 5 is reset without being activated, its upper surface is lower than the inner bottom surface of the fixed-piece square 2, thus completely preventing the occurrence of such unintended operations.

[0044] To better protect the internal components of the central disk, especially the circuit control board 7, such as... Figure 3 As shown, the mahjong set-piece center plate also includes an outer cover 10 and a connecting block 11; the outer cover 10 covers the back of the center plate surface 1; one end of the connecting block 11 is connected to the support member on the back of the dice plate 3, and the other end is connected to the lifting mechanism of the mahjong machine host, thereby driving the center plate surface 1 to move up and down, realizing the shuffling function of the mahjong machine.

[0045] A mahjong machine includes a mahjong machine tabletop, a central plate located at the center of the mahjong machine tabletop, a mahjong machine main unit, and a base supporting the main unit; the central plate is the mahjong tile set center plate described above.

[0046] The aforementioned structures, such as the circuit control board 7 of the control mechanism, or the main unit of the mahjong machine, the lifting mechanism, the dice plate 3, the display screen 6, etc., are all common existing structures of mahjong machines and are not within the scope of protection of this application. This application mainly solves the problem of fixed suits by setting fixed suits 2 on the central plate 1 and making it better cooperate with components such as the dice plate button 5 and the display screen 6. It also makes the arrangement of the central plate more compact, which not only makes it less likely to be accidentally touched, but also allows players to better identify the missing suits and ensures the smoothness of the game, which is very popular among players.

[0047] Unless otherwise specified, fixed connections can be riveting, welding, bolting, etc., while movable connections can be hinged, etc.
