Description
Technical Field
[0001] The utility model belongs to the technical field of mahjong machine equipment, and particularly relates to a lifting drive structure for a mahjong machine lifting board. Background Art
[0002] Most existing fully automatic mahjong machines use a vertically raised card mechanism, which takes up a lot of space. Therefore, to reduce this space, a tilted card mechanism was adopted. A crank rocker controls the up and down movement of the card plate. However, the crank rocker is composed of multiple connecting rods, resulting in a complex structure that cannot guarantee stable transmission during operation, easily causing friction, damage to parts, and malfunctions. Summary of the Invention
[0003] The purpose of the utility model is to solve the above problems and provide a lifting drive structure for a mahjong machine lifting plate.
[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a lifting drive structure for a mahjong machine card lifting plate, comprising a card lifting plate movably disposed within a card lifting channel on one side of an upper card rack, a card lifting plate lifting rocker arm assembly provided at the lower end of the card lifting plate, a lifting plate block provided on one side of the card lifting channel via a sliding mounting structure, a lifting drive mechanism capable of driving the lifting plate block to slide back and forth in the same direction along the card lifting channel, and the lifting plate block linked to the card lifting rocker arm assembly via a linkage structure. The lifting plate block moves via the lifting drive mechanism, and the movement of the lifting plate block drives the lifting plate lifting rocker arm assembly, thereby controlling the operation of the card lifting plate. The overall structure is simple, and operational stability is improved.
[0005] In the aforementioned mahjong machine tile-lifting plate lifting and driving structure, the tile loading rack is provided with a mounting slot located on one side of the tile-lifting channel. A tile mounting seat is provided within the mounting slot, oriented in the same direction as the tile-lifting channel. The lift plate block slides axially within the plate mounting seat via a sliding mounting structure. The plate mounting seat ensures stable operation of the lift plate block, thus safeguarding the operation of the tile-lifting plate.
[0006] In the aforementioned mahjong machine card lifting plate lifting drive structure, the sliding mounting structure includes two mutually parallel guide ribs axially disposed within the plate mounting seat. The lower side of the lifting plate slides against the upper side of the guide ribs. One side of the lifting plate has an axially extending sliding portion. A pressure plate is mounted within the plate mounting seat at the upper end of one side of the lifting plate, and one side of the pressure plate has a guide groove slidably connected to the sliding portion. The pressure plate is used to secure the lifting plate, ensuring stable operation of the lifting plate within the plate mounting seat and preventing movement and misalignment.
[0007] In the aforementioned mahjong machine lifting plate drive structure, the sliding portion is formed by an inwardly recessed edge of one side of the lifting plate block, the pressure plate does not extend beyond the lifting plate block, and a sliding limit step corresponding to the pressure plate is provided at the end of the lifting plate block on the side with the sliding portion. The lifting plate block is provided with an outwardly protruding sliding limit portion on the side away from the sliding portion, and the sliding limit portion corresponds to a limit groove on one side of the plate mounting seat. The sliding limit portion and the limit groove further provide a guiding and limiting function, thereby enhancing the stable movement of the lifting plate block.
[0008] In the above-mentioned driving structure for lifting the card board of a mahjong machine, the linkage structure is a rack and pinion linkage structure.
[0009] In the aforementioned mahjong machine tile-lifting plate drive structure, the linkage mechanism includes a linkage gear, which is mounted on a plate mounting base near the tile-lifting channel and rotated by a linkage shaft. The linkage shaft is connected to the tile-lifting plate rocker assembly. A linkage rack, extending axially along the lift plate and meshing with the linkage gear, is located on the underside of the lift plate. The use of the linkage gear and linkage rack for transmission simplifies the structure, improves stability, and reduces operational failures.
[0010] In the above-mentioned lifting drive structure of the mahjong machine card lifting plate, the lifting and sliding drive mechanism includes a lifting and sliding drive motor arranged at the lower end of the upper card rack, and the motor shaft of the lifting and sliding drive motor passes through the boss located at the upper end of the upper card rack and is connected to one end of the lifting slide block through the lifting and sliding rocker arm assembly.
[0011] In the aforementioned mahjong machine lift plate drive structure, the lift rocker arm assembly includes a lift rocker arm mounted on the motor shaft of the lift drive motor. One end of the lift rocker arm includes a lift pin, which movably extends through a transverse groove at one end of the lift plate. The lift drive motor directly controls the lift plate through the lift rocker arm, reducing the number of moving parts and resulting in improved transmission efficiency and performance.
[0012] In the above-mentioned mahjong machine card-lifting plate lifting drive structure, the card-lifting plate lifting rocker arm assembly includes a card-lifting seat arranged on the lower side of the middle part of the card-lifting plate, and one side of the card-lifting seat has an arc-shaped card-lifting groove. The linkage shaft is passed through the card-lifting channel and a card-lifting rocker arm is provided on the linkage shaft. One end of the card-lifting rocker arm is provided with a card-lifting shaft pin movably arranged in the arc-shaped card-lifting groove.
[0013] In the above-mentioned lifting drive structure of the card-lifting plate of a mahjong machine, the card-lifting channel is arranged in an inclined shape, and one end of the card-lifting plate is hingedly arranged at the end of the card-lifting channel located at a higher position.
[0014] Compared with the existing technology, the advantages of this utility model are:
[0015] 1. The device utilizes the mutual cooperation between the pressure plate and the plate mounting seat to ensure the stable movement of the lifting slide block in the plate mounting seat, thereby reducing the phenomenon of tilting and dislocation of the lifting slide block.
[0016] 2. The lifting slide block of the device is connected to the lifting plate lifting rocker arm assembly through a linkage structure to control the operation of the lifting plate. At the same time, the lifting slide block is connected to the lifting drive motor through the lifting rocker arm assembly to control the movement of the lifting slide block. The structure is simple and easy to control, which improves the performance of the lifting plate and the stability of the structure while saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

One side of the pressure plate 33 has a guide groove 34 slidably connected to the sliding portion 32. The pressure plate 33 is used to secure the lifting slide block 13, ensuring stable operation of the lifting slide block 13 within the plate mounting seat 15 and preventing movement and misalignment.
[0030] The sliding portion 32 is formed by an inward depression on one side of the lifting plate 13, and the pressure plate 33 does not extend beyond the lifting plate 13. A sliding stop step 35 corresponding to the pressure plate 33 is provided at the end of the lifting plate 13 on the side with the sliding portion 32. An outwardly protruding sliding stop 36 is provided on the side of the lifting plate 13 away from the sliding portion 32, and the sliding stop 36 corresponds to a stop groove 37 on one side of the plate mounting seat 15. The sliding stop 36 and the stop groove 37 further provide a guiding and limiting function, thereby enhancing the stable movement of the lifting plate 13.
