Technical Field
[0001] This utility model relates to the field of mahjong machine technology, and in particular to a tile-lifting structure for a mahjong machine. Background Technology
[0002] Mahjong is widely enjoyed as a recreational activity and is also considered a competitive sport. Traditional mahjong machines use a lifting plate to vertically raise the mahjong tiles onto the table. The square tiles are parallel to the edges of the table after being raised, resulting in an unbalanced arrangement. Players need to manually move and angle the tiles before drawing a tile, and the tiles are prone to tipping over during this process, causing inconvenience. Furthermore, current technology uses separate motors for both the pushing and raising mechanisms, leading to a large number of motors in automatic mahjong machines, complex structures, and high costs for motors and control circuits. In addition, the numerous motors also result in a large footprint, cumbersome assembly, and low production efficiency.
[0003] Therefore, it is necessary to invent a tile-lifting structure for a mahjong machine to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a tile-lifting structure for a mahjong machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tile-lifting structure for a mahjong machine, including a track assembly;
[0006] The track assembly includes a housing, with a mahjong tile moving groove integrally formed around the top edge of the housing, and a tile raising groove integrally formed on one side of the upper surface of the housing, with one end of the tile raising groove communicating with one end of the mahjong tile moving groove, and a tile raising component installed inside the tile raising groove.
[0007] The lifting plate assembly includes a lifting plate gear fixing plate, which is fixedly disposed on the other side of the bottom of the housing. A second support plate is rotatably disposed on the top of the lifting plate gear fixing plate. The lifting plate gear is integrally formed on the top of the second support plate. Arc-shaped low groove and high groove are integrally formed on both sides of the bottom end of the second support plate, and the two ends of the low groove are respectively connected to the two ends of the high groove. A rack sliding rail is fixedly installed on the bottom end of the housing near the bottom of the lifting plate groove. A drive shaft is disposed between the second support plate and the lifting plate gear fixing plate. One end of the drive shaft extends into the groove of the rack sliding rail, and the top part of the drive shaft near the rack sliding rail is provided with serrations.
[0008] Preferably, a rocker arm gear fixing seat is fixedly installed through the inner wall of the side of the lifting slot near the rack sliding track, and a drive shaft is rotatably installed on the rocker arm gear fixing seat. A rocker arm gear is fixedly installed at one end of the drive shaft near the rack sliding track, and the rocker arm gear is meshed with the saw teeth on the drive shaft.
[0009] Preferably, a lifting rocker arm is fixedly provided at the other end of the drive shaft, and a drive shaft bearing is fixedly provided at the top end of the drive shaft near the second support plate, and the drive shaft bearing is adapted to both the low-position groove and the high-position groove.
[0010] Preferably, a tile-raising plate bracket is fixedly provided at the bottom inner wall of the tile-raising groove away from the mahjong moving groove, and a tile-raising plate shaft is fixedly installed on the tile-raising plate bracket.
[0011] Preferably, a drive tooth groove is integrally formed at the top center of the housing, and a drive motor is fixedly installed at the bottom of the housing.

A signal magnet is inlaid and installed at the top edge of the second support plate.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] This invention, through the design of the tile-lifting assembly, eliminates the need for a separate motor for the overall drive of the tile-lifting assembly. The drive motor on the track assembly drives the tile-pushing gear, which in turn rotates the tile-lifting gear. This rotation of the tile-lifting gear also rotates the support plate. Due to the low and high slots, the transmission shaft slides simultaneously, opening and closing the tile-lifting plate. During tile placement, the transmission shaft bearing is located inside the low slot, causing one side of the tile-lifting plate to descend and remain in place, allowing the mahjong tiles to smoothly enter the tile-lifting plate and the top of the table. After placement, the transmission shaft bearing slides into the high slot, causing one side of the tile-lifting plate to rise, thus completing the placement. This invention easily achieves proper mahjong tile placement without manual pushing, and the tile-lifting assembly does not require a separate motor, reducing costs, simplifying the structure, facilitating assembly, and enhancing practicality.

A tile-lifting component 2 is installed inside the tile-lifting groove 104. A tile-lifting plate bracket 106 is fixedly installed at the bottom inner wall of the tile-lifting groove 104 away from the mahjong moving groove 102. A tile-lifting plate shaft 107 is fixedly installed on the tile-lifting plate bracket 106. A drive gear groove 105 is integrally formed in the middle of the top of the housing 101. A drive motor 103 is fixedly installed at the bottom of the housing 101, and the drive motor 103 drives the tile-pushing gear inside the drive gear groove 105.
[0028] The card-lifting assembly 2 includes a card-lifting gear fixing plate 201, which is fixedly disposed on the other side of the bottom of the housing 101. A second support plate 202 is rotatably disposed on the top of the card-lifting gear fixing plate 201. A card-lifting gear 213 is integrally formed on the top of the second support plate 202. The card-lifting gear 213 meshes with the card-pushing gear, and the number of gears of the card-lifting gear 213 and the card-pushing gear are the same. Arc-shaped low groove 215 and high groove 216 are integrally formed on both sides of the bottom end of the second support plate 202, and the two ends of the low groove 215 are respectively connected to the two ends of the high groove 216.
[0029] A rack and pinion sliding rail 203 is fixedly installed at the bottom of the housing 101 near the bottom of the lifting slot 104. A drive shaft 204 is provided between the second support plate 202 and the lifting gear fixing plate 201. One end of the drive shaft 204 extends into the slot of the rack and pinion sliding rail 203, and the top of the drive shaft 204 near the end of the rack and pinion sliding rail 203 is provided with serrations. A rocker arm gear fixing seat 206 is fixedly installed through the inner wall of the lifting slot 104 near the rack and pinion sliding rail 203, and the drive shaft 204 is rotatably mounted on the rocker arm gear fixing seat 206. The end of the drive shaft 204 near the rack and pinion sliding rail 203 is fixedly installed through the rack and pinion sliding rail 203. A rocker arm gear 210 is fixedly installed, and the rocker arm gear 210 meshes with the sawtooth on the drive shaft 204. When the lifting plate 211 is horizontal, one end of the rocker arm gear 210 meshes with the sawtooth on the drive shaft 204. The other end of the drive shaft 204 is fixedly equipped with a lifting rocker arm 205. A drive shaft bearing 212 is fixedly installed at the top end of the drive shaft 204 near the second support plate 202. The drive shaft bearing 212 is compatible with both the low-position groove 215 and the high-position groove 216. The low-position groove 215 is a concentric circle centered on the axis of rotation of the support plate 202, while section a of the high-position groove 216 is a concentric circle, and sections c and d of the high-position groove 216 are arc-shaped (e.g., Figure 8As shown, a, b, c, and d represent the various positions of the low slot 215 and the high slot 216. A signal magnet 214 is embedded and installed on the top edge of the second support plate 202. The signal magnet 214 is used to align with the Hall element on the track assembly 1 after the support plate 202 rotates one revolution. The Hall element sends a signal to stop the drive motor 103, stop the tile lifting assembly 2, keep the tile lifting plate 211 horizontal, and allow the mahjong to be used normally.
[0030] A lifting plate 211 is provided at the opening of the lifting slot 104, and the lifting plate 211 is adapted to the lifting slot 104. One end of the lifting plate 211 is rotatably connected to the lifting plate shaft 107. A support block 207 is fixedly provided at the middle of the bottom end of the lifting plate 211. A side groove 208 is integrally formed on the side of the support block 207 near the lifting rocker arm 205. The side groove 208 is inclined. A rocker arm bearing 209 adapted to the side groove 208 is fixedly installed at the top of the side of the lifting rocker arm 205 near the support block 207. With the setting of the lifting assembly 2, the overall drive of the lifting assembly 2 does not require a separate motor. Only the drive motor 103 on the track assembly 1 drives the pushing gear, which drives the lifting gear 213 to rotate. The rotation of the lifting gear 213 will also drive the lifting gear 213 to rotate. When the movable support plate 202 rotates, the low slot 215 and the high slot 216 simultaneously drive the drive shaft 204 to slide. When the drive shaft 204 slides, it can drive the lifting plate 211 to open or close. When placing the mahjong tile, the drive shaft bearing 212 is located inside the low slot 215, causing one side of the lifting plate 211 to descend and remain in place, allowing the mahjong tile to smoothly enter the lifting plate 211 and the top of the table. After the tile is placed, the drive shaft bearing 212 slides into the high slot 216, and one side of the lifting plate 211 rises, thus completing the tile placement. This utility model can easily achieve reasonable mahjong tile placement without manual pushing of the mahjong tile placement. Furthermore, the lifting component 2 does not require a separate motor, reducing costs while simplifying the structure, facilitating assembly, and making it highly practical.
[0031] Working principle of this utility model:
[0032] During the shuffling process of the mahjong machine, all four sides have completed the shuffling. When the required number of mahjong tiles are pushed into the mahjong moving slot 102, all motors stop, the mahjong tiles are stored in the mahjong moving slot 102, and the mahjong machine enters the waiting state for tile lifting. The signal magnet 214 on the support plate 202 is aligned with the Hall element on the housing 101.
[0033] After the tile-raising command is issued, the drive motor 103 rotates, driving the tile-pushing gear to rotate. The tile-pushing gear rotates counterclockwise, driving the tile-raising gear 213 and the support plate 202 to rotate. At the same time, the tile-pushing gear drives the tile-pushing arm to push the mahjong tiles into the tile-raising groove 104. The transmission shaft bearing 212 at the right end of the transmission shaft 204 leaves section a and enters section b of the raising gear. The transmission shaft bearing 212 drives the transmission shaft 204 to move closer to the support plate 202. The rocker arm gear 210 rotates clockwise, the tile-raising rocker arm 205 rotates clockwise, and the tile-raising plate 211 rotates clockwise around the tile-raising plate shaft 107. The right end of the tile-raising plate 211 descends. When the tile-raising gear 213 rotates to the right end of the transmission shaft bearing 212 at the right end of section b, the right end of the tile-raising plate 211 descends into place.
[0034] Immediately afterwards, the lifting gear 213 continues to rotate, and the transmission shaft bearing 212 at the right end of the transmission shaft 204 enters the d section of the low position groove 215. The transmission shaft bearing 212 remains stationary, the lifting plate 211 remains stationary in the low position, and the mahjong tile continues to slide towards the table.
[0035] The lifting gear 213 continues to rotate. When the transmission shaft bearing 212 moves from section d to section c, all the mahjong tiles are on the table and at the top of the lifting plate 211. Then, the transmission shaft bearing 212 drives the transmission shaft 204 to move away from the support plate 202. The rocker arm gear 210 reverses, the lifting rocker arm 205 reverses, the lifting plate 211 reverses around the lifting plate shaft 107, the right end of the lifting plate 211 rises, and the mahjong tiles on the lifting plate 211 rise with the lifting plate 211.
[0036] The lifting gear 213 continues to rotate, and the transmission shaft bearing 212 moves from section c to section a. At this time, the lifting plate 211 rises to a horizontal position, and all the mahjong tiles are placed. The lifting gear 213 continues to rotate, and the transmission shaft bearing 212 rotates to the end of section a. The lifting plate 211 remains horizontal. At this time, the signal magnet 214 on the support plate 202 aligns with the Hall element on the housing 101. The Hall element sends a signal to stop the drive motor 103, thereby stopping the entire lifting assembly 2 and keeping the lifting plate 211 horizontal. The lifting is complete, and the next lifting command is issued to begin the next round of pushing and lifting tile cycle.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
