Description

Technical Field

[0001] This utility model relates to the field of dice game technology, and in particular to a dice game and mahjong machine. Background Technology

[0002] Mahjong tiles are small rectangular blocks made of bamboo, bone, or plastic, engraved with patterns or characters. It's a four-player domino game popular in Chinese cultural spheres. A mahjong machine is a machine used to play mahjong. Traditionally, players need to manually arrange and stack the tiles, which is tedious and laborious. Now, automatic mahjong machines have been invented. With just a touch of a button, the tiles are automatically stacked, allowing players to enjoy the game more quickly. The stacking mechanism is located inside the machine; the dice pan in the center of the machine needs to be raised and the tiles pushed in to stack them.

[0003] Chinese utility model patent CN203577290U discloses a mahjong machine dice tray, including a body, a dice groove, connecting pillars, and a circuit board. The body is circular with several openings on its surface, each with a button. A cylindrical dice groove is recessed at the center of the body, with grooves on its inner wall. A motor is located at the lower end of the dice groove, connected to a soft pad inside the groove. A glass cover is fixed to the top of the dice groove by a fixing ring connected to the body. Several connecting pillars are mounted on the back of the body, with bolts connecting the ends of the pillars to the circuit board. A start button is mounted on the circuit board, fitted under the button. Several support rods are provided on the back of the body, with the button resting on them. Several connecting pieces with circular holes are also provided on the back of the body. The advantages of this utility model are: easy to manufacture, novel structure, strong and stable connection, even throwing, and long service life.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: During use, the operator needs to connect the bottom of the dice pan to the electric lifting rod on the mahjong machine to move the dice pan up and down. In actual use, when the operator fully raises the dice pan, it relies entirely on the electric lifting rod for stability, resulting in poor stability. Furthermore, at this point, the electric lifting rod and the dice pan are susceptible to irreversible damage under external forces, leading to a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a dice plate and a mahjong machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dice plate, including a mahjong machine body, a communicating groove is formed on the upper surface of the mahjong machine body, an electric telescopic rod is installed inside the mahjong machine body, a dice box is installed at the upper end of the electric telescopic rod, a dice plate body is installed at the upper end of the dice box, the dice plate body is slidably connected to the communicating groove, a motor is installed on the dice box, a stabilizing plate is fixed on the side wall of the dice box, three driving grooves arranged in a circumferential array are formed through the upper surface of the stabilizing plate, a sliding groove is formed on the inner wall of each of the three driving grooves, and three stabilizing components for improving the stability of the dice plate body are installed on the stabilizing plate.

[0007] By adopting the above technical solution, when a game of mahjong ends, the staff needs to shuffle the tiles. At this time, the staff needs to activate the electric telescopic rod, which moves the dice box to its highest point, thus moving it above the connecting slot. Then, the staff only needs to push the mahjong tiles on the surface of the mahjong machine to move them into the connecting slot. During this process, three stabilizing components continuously support the dice disc body, thereby improving its stability and reducing the probability of damage to the dice disc body under external forces.

[0008] Furthermore, the stabilizing component includes a fixed block fixed to the top wall of the mahjong machine body, a sliding block slidably disposed in a sliding groove, a first rotating groove formed on the side wall of the fixed block, a second rotating groove formed on the bottom surface of the sliding block, and the stabilizing component also includes a first rotating block slidably disposed in the first rotating groove, a second rotating block slidably disposed in the second rotating groove, a rotating rod rotatably disposed on the first rotating block and the second rotating block, and a limiting device for limiting the first rotating block and the second rotating block.

[0009] Furthermore, the sliding grooves are provided in six pairs and symmetrically distributed on the inner walls of the three drive grooves.

[0010] By adopting the above technical solution, when workers need to install the stabilizing components, they need to move the dice box to its highest point under the action of the electric telescopic rod, and slide the first rotating block into the first rotating groove. This allows the first rotating block to remain stable under the action of the limiting device. Furthermore, workers need to connect the second rotating block to the second rotating groove, which also allows the second rotating block to remain stable under the action of the limiting device, thus stabilizing the rotating rod. Once all three rotating rods are installed, they cooperate to support the dice box, thereby reducing the probability of damage to the dice box when subjected to external forces.

[0011] Furthermore, the limiting device includes two fixing rods that are sequentially fixed to the inner walls of the first rotating groove and the second rotating groove. Each of the two fixing rods has a limiting groove on its side wall. The limiting device also includes two limiting rods that are slidably disposed in the two limiting grooves and two compression springs that are sequentially fixed to the side walls of the two limiting rods at one end. Each of the first rotating block and the second rotating block has a fixing groove that matches the fixing rod on its side wall. The other ends of the two compression springs are sequentially fixed to the inner walls of the two limiting grooves.

[0012] Furthermore, each of the two fixing grooves has a limiting hole on its inner wall that matches the limiting rod, and each of the two limiting holes has a connecting hole through its inner wall.

[0013] Furthermore, inclined surfaces are provided on the sidewalls of the multiple limiting rods away from the compression spring.

[0014] By adopting the above technical solution, when the worker connects the first rotating block to the first rotating groove, the fixed rod connects to the fixed groove, allowing the limiting rod to move completely into the limiting groove under the action of the inclined surface. Subsequently, when the fixed rod presses against the inner wall of the fixed groove, the limiting rod aligns with the limiting hole, causing the limiting rod to automatically reset under the action of the compression spring. This allows one end of the limiting rod to connect with the limiting hole, thus blocking the fixed rod and connecting the first rotating block to the first rotating groove. Furthermore, when the first rotating block is damaged and needs replacement, the worker uses a round rod-shaped tool and slides it into the connecting hole to press the tool against the upper surface of the limiting rod, separating the limiting rod from the limiting hole. This reduces the difficulty of maintenance for the rotating rod and other devices.

[0015] Furthermore, a first stop block for blocking the first rotating block is fixed on the side wall of the fixed block, and a second stop block for blocking the second rotating block is provided on the side wall of the sliding block.

[0016] By adopting the above technical solution, when the worker connects the first rotating block to the first rotating groove, the first stop block blocks the first rotating block, thereby increasing the difficulty of aligning the fixing rod with the fixing groove at this time, and thus reducing the difficulty of the worker installing the first rotating block.

[0017] This application also discloses a mahjong machine, including the aforementioned dice pan, wherein the upper surface of the main body of the mahjong machine is provided with four receiving slots, and each of the four receiving slots is provided with a protective sleeve.

[0018] By adopting the above technical solution, the protective cover reduces the probability of staff feeling pain when touching the edge of the mahjong machine, thereby improving the staff's user experience.

[0019] In summary, this utility model has the following beneficial effects: 1. In this application, when a game of mahjong ends, the staff needs to shuffle the tiles. At this time, the staff needs to activate the electric telescopic rod, which moves the dice box to its highest point, thus moving it above the connecting slot. Then, the staff only needs to push the mahjong tiles on the surface of the mahjong machine to move them into the connecting slot. During this process, three stabilizing components continuously support the dice disc body, thereby improving the stability of the dice disc body and reducing the probability of damage to the dice disc body under external forces. 2. In this application, when the worker needs to install the stabilizing components, the worker needs to move the dice box to its highest point under the action of the electric telescopic rod, and slide the first rotating block into the first rotating groove, so that the first rotating block can be kept stable under the action of the limiting device. Furthermore, the worker needs to connect the second rotating block to the second rotating groove, so that the second rotating block can be kept stable under the action of the limiting device, thereby keeping the rotating rod stable. After all three rotating rods are installed, the three rotating rods cooperate with each other and support the dice box, thereby reducing the probability of damage to the dice box when subjected to external forces. 3. In this application, when the worker connects the first rotating block to the first rotating groove, the fixed rod connects to the fixed groove, thereby allowing the limiting rod to move completely into the limiting groove under the action of the inclined surface. Subsequently, when the fixed rod presses against the inner wall of the fixed groove, the limiting rod aligns with the limiting hole, causing the limiting rod to automatically reset under the action of the compression spring, thereby connecting one end of the limiting rod to the limiting hole, thus blocking the fixed rod and connecting the first rotating block to the first rotating groove. Furthermore, when the first rotating block is damaged and needs to be replaced, the worker needs to use a round rod-shaped tool and slide it into the connecting hole to press the tool against the upper surface of the limiting rod, thereby separating the limiting rod from the limiting hole, thus reducing the difficulty for the worker to repair the rotating rod and other devices.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] like Figure 1-6 As shown in the illustration, this application discloses a dice tray, including a mahjong machine body 1, an electric telescopic rod 2, a dice box 21, a dice tray body 3, a motor 31, a stabilizing plate 4, a stabilizing component 5, a first stop block 81, a second stop block 82, and a protective sleeve 9. A connecting groove 11 is formed on the upper surface of the mahjong machine body 1, and the electric telescopic rod 2 is installed inside the mahjong machine body 1. The dice box 21 is installed at the upper end of the electric telescopic rod 2 and is used to hold the dice. The dice tray body 3 is installed at the upper end of the dice box 21, and the dice tray body 3 is slidably connected to the connecting groove 11. The motor 31 is installed on the dice box 21. When the operator needs to throw the dice, the operator only needs to turn on the motor 31, which will cause the motor 31 to strike the dice box 21, thereby changing the number of points on the dice inside the dice box 21. The stabilizing plate 4 is a circular plate structure and is fixed to the side wall of the dice box 21.

[0024] The upper surface of the stabilizing plate 4 has three drive grooves 41 arranged in a circular array. Each of the three drive grooves 41 has a sliding groove 42 on its inner wall. Three stabilizing components 5 are installed sequentially on the stabilizing plate 4 to improve the stability of the dice pan body 3. The stabilizing components 5 include a fixed block 51, a sliding block 52, a first rotating block 53, a second rotating block 54, a rotating rod 55, and a limiting device 6. The fixed block 51 is a rectangular block structure and is fixed to the inner top wall of the mahjong machine body. The sliding block 52 is a rectangular block structure and is slidably disposed within the sliding groove 42. The side wall of the fixed block 51 has a first rotating groove 521, and the bottom surface of the sliding block 52 has a second rotating groove 522. The first rotating block 53 is a rectangular block structure and is slidably disposed within the first rotating groove 521. The second rotating block 54 is a rectangular block structure and is slidably disposed within the second rotating groove 522. The rotating rod 55 is a rod-shaped structure. The rotating rod 55 is rotatably mounted on the first rotating block 53 and the second rotating block 54. The sliding groove 42 has six grooves and is symmetrically distributed in pairs on the inner wall of the three driving grooves 41.

[0025] When the worker needs to install the stabilizing component 5, the worker needs to move the dice box 21 to its highest point under the action of the electric telescopic rod 2, and slide the first rotating block 53 into the first rotating groove 521, so that the first rotating block 53 can be kept stable under the action of the limiting device 6. Further, the worker needs to connect the second rotating block 54 into the second rotating groove 522, so that the second rotating block 54 can be kept stable under the action of the limiting device 6, thereby keeping the rotating rod 55 stable. After all three rotating rods 55 are installed, the three rotating rods 55 cooperate with each other and support the dice box 21, thereby reducing the probability of damage to the dice box 21 when subjected to external forces.

[0026] The limiting device 6 is used to limit the movement of the first rotating block 53 and the second rotating block 54. The limiting device 6 includes a fixed rod 61, a limiting rod 62, and a compression spring 63. The fixed rod 61 is a rectangular rod-shaped structure, and two fixed rods 61 are provided and are fixed sequentially on the inner walls of the first rotating groove 521 and the second rotating groove 522. Limiting grooves 611 are provided on the side walls of both fixed rods 61. The limiting rod 62 is a rectangular rod-shaped structure, and two limiting rods 62 are provided and are slidably disposed in the two limiting grooves 611 respectively. Inclined surfaces are provided on the side walls of the multiple limiting rods 62 away from the compression springs 63. Two compression springs 63 are provided, and one end of the two compression springs 63 is fixed sequentially on the side walls of the two limiting rods 62. Fixed grooves 64 that match the fixed rods 61 are provided on the side walls of both the first rotating block 53 and the second rotating block 54. The other ends of the two compression springs 63 are fixed sequentially on the inner walls of the two limiting grooves 611. The inner walls of the two fixing grooves 64 are provided with limiting holes 7 that match the limiting rods 62, and the inner walls of the two limiting holes 7 are provided with connecting holes 8.

[0027] When the operator connects the first rotating block 53 to the first rotating groove 521, the fixing rod 61 connects to the fixing groove 64, causing the limiting rod 62 to move completely into the limiting groove 611 under the action of the inclined surface. Subsequently, when the fixing rod 61 presses against the inner wall of the fixing groove 64, the limiting rod 62 aligns with the limiting hole 7, causing the limiting rod 62 to automatically reset under the action of the compression spring 63. This causes one end of the limiting rod 62 to connect with the limiting hole 7, thus blocking the fixing rod 61 and connecting the first rotating block 53 to the first rotating groove 521. Furthermore, when the first rotating block 53 is damaged and needs to be replaced, the operator needs to use a round rod-shaped tool and slide it into the connecting hole 8. This allows the tool to press against the upper surface of the limiting rod 62, separating the limiting rod 62 from the limiting hole 7, thereby reducing the difficulty of maintenance for the rotating rod 55 and other devices.

[0028] The first stop block 81 is a block-shaped structure, fixed to the side wall of the fixed block 51, and is used to block the first rotating block 53. The second stop block 82 is a block-shaped structure, located on the side wall of the sliding block 52, and is used to block the second rotating block 54. When the operator connects the first rotating block 53 to the first rotating groove 521, the first stop block 81 blocks the first rotating block 53, thereby increasing the difficulty of aligning the fixed rod 61 with the fixed groove 64, and thus reducing the difficulty of the operator installing the first rotating block 53.

[0029] This embodiment also discloses a mahjong machine, including the aforementioned detachable storage mechanism.

[0030] The upper surface of the mahjong machine body 1 has four receiving slots 83. The protective cover 9 is made of silicone and has four covers arranged sequentially in the four receiving slots 83. The protective cover 9 reduces the probability of workers feeling pain when touching the edge of the mahjong machine body 1, thereby improving the user experience.

[0031] The operating principle of the dice tray and mahjong machine in this embodiment is as follows: When a game of mahjong ends, the staff needs to shuffle the tiles. At this time, the staff needs to activate the electric telescopic rod 2, which moves the dice box 21 to its highest point under the action of the electric telescopic rod 2, thereby moving the dice box 21 above the connecting groove 11. At this time, the staff only needs to push the mahjong tiles on the surface of the mahjong machine body 1 to move the mahjong tiles into the connecting groove 11. During this process, the three stabilizing components 5 continuously support the dice tray body 3, thereby improving the stability of the dice tray body 3 and reducing the probability of damage to the dice tray body 3 under the action of external forces.

[0032] 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.
