Technical Field
[0001] The utility model belongs to the technical field of mahjong machine equipment, and particularly relates to an intermittent motion mechanism for raising tiles in a mahjong machine. Background Art
[0002] There are many types of automatic mahjong machines with sloped tile loading on the market. One of them is an arc-shaped mahjong machine with sloped tile loading. It controls the lifting and lowering of the tile lifting plate through a tile lifting motor connected to multiple drive rods, thereby solving the problem of occupying a large space caused by the previous vertical lifting mechanism. However, due to the control through multiple drive rods, the transmission distance is long, and after long-term use, the connection will wear and dislocation will occur, thereby affecting the normal lifting and lowering of the tile lifting plate. Summary of the Invention
[0003] The purpose of the utility model is to solve the above problems and provide an intermittent motion mechanism for raising tiles in a mahjong machine.
[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a mahjong machine intermittent motion mechanism for raising cards, comprising a card raising slot disposed on one side of a card storage track frame, a card raising plate movably disposed in the card raising slot via a card raising plate lifting structure, a movable slot disposed in the same direction as the card raising slot on one side of the card raising slot, a movable frame movably disposed in the movable slot, one end of the movable frame being linked to the card raising plate lifting structure via a reciprocating gear rack linkage structure, and the other end of the movable frame being connected to an incomplete gear transmission structure for raising cards disposed on the card storage track frame and capable of driving the movable frame to reciprocate along the movable slot. The incomplete gear transmission structure for raising cards drives the movable frame in motion, and the movable frame is connected to the card raising plate via the card raising plate lifting structure, thereby realizing the lifting and lowering motion of the card raising plate.
[0005] In the above-mentioned intermittent motion mechanism for advancing tiles in a mahjong machine, the tile advancing slot is inclined and one end of the tile advancing slot is higher than the other end, and one end of the tile advancing plate is hingedly arranged at the higher end of the tile advancing slot.
[0006] In the aforementioned intermittent mechanism for raising tiles in a mahjong machine, the lifting structure for the tile-raising plate includes a tile-raising seat disposed on the lower middle portion of the tile-raising plate. A tile-raising plate lifting track is provided on one side of the tile-raising seat, and a tile-raising rocker arm is movably mounted within the track. The rocker arm is movably connected to the tile-raising seat of the tile-raising plate to control the raising and lowering of the tile-raising plate.
[0007] In the aforementioned intermittent mechanism for advancing tiles in a mahjong machine, the upper end of the tile storage track frame has a mounting boss, and a movable frame mounting seat is mounted within the movable groove. The movable frame is curved, with one end slidingly disposed within the movable frame mounting seat and the other end slidingly inserted through the mounting boss. The movable frame is slidably connected to the movable frame mounting seat and the tile storage track frame via a sliding guide structure. The movable frame is located at one end of the mounting boss for connection to the driver, while the movable frame is located at one end of the movable frame mounting seat for connection to the tile advancement plate.
[0008] In the aforementioned intermittent card-elevating mechanism for a mahjong machine, the sliding guide structure includes guide grooves disposed at both ends of the movable frame and extending axially along the movable frame. The movable frame mounting seat and the card storage track frame are each provided with guide posts extending through the guide grooves on one side of the mounting boss, and the guide posts and guide grooves are slidably connected. A guide rib abutting against the lower side of one end of the movable frame is further provided within the movable frame mounting seat. A limiting step is provided on one side of the movable frame mounting seat, and a limiting portion cooperating with the limiting step is provided on the outer side of one end of the movable frame. The guide posts and guide ribs can improve the stability of the movable frame's movement and prevent movement deviation.
[0009] In the aforementioned intermittent card-elevating mechanism for a mahjong machine, the reciprocating rack-and-pinion linkage structure includes a linkage rack disposed below one end of a movable frame within a movable frame mounting seat and extending axially along the movable frame. A linkage gear is mounted within the movable frame mounting seat via a gear shaft at its lower end. The linkage rack and the linkage gear mesh with each other. The gear shaft extends beyond the movable frame mounting seat into the card-elevating slot and is connected to a card-elevating rocker arm. The linkage rack meshes with the linkage gear, causing the card-elevating rocker arm to swing as the movable frame moves.
[0010] In the aforementioned intermittent card-elevating mechanism for a mahjong machine, the card-elevating incomplete gear transmission structure includes a rotating portion rotatably mounted within a mounting boss. The rotating portion has two integral sector-shaped incomplete gears circumferentially disposed on its outer circumference. A transmission gear rotatably mounted within the mounting boss, capable of meshing with either of the two sector-shaped incomplete gears, is connected to one end of a movable frame via a reciprocating transmission assembly. Engaging the transmission gear with one of the sector-shaped incomplete gears causes the movable frame to move forward, while engaging the other sector-shaped incomplete gear causes the movable frame to move backward. Furthermore, an incomplete card-pushing gear connected to a card-pushing device is disposed above the rotating portion, enabling the card-pushing device to achieve intermittent motion.
[0011] In the aforementioned intermittent motion mechanism for advancing tiles in a mahjong machine, the reciprocating transmission assembly includes a rotating seat disposed coaxially with and below the transmission gear. A pin is eccentrically disposed at the lower end of the rotating seat. The movable frame, located near the mounting boss, has a slide extending along its width, within which the pin slides. This simple structure connects the slide via the pin. When the rotating seat rotates, driven by the transmission gear, it causes the movable frame to begin moving.
[0012] In the aforementioned intermittent motion mechanism for advancing tiles in a mahjong machine, the rotating portion is connected to a worm gear transmission assembly disposed at the lower end of a tile storage track frame, and the worm gear transmission assembly is connected to a drive motor. The worm gear transmission assembly comprises a worm wheel and a worm member. The worm member is connected to the drive motor via a drive shaft, and the worm wheel is connected to the transmission portion via a connecting shaft. The worm wheel and worm member mesh with each other.
[0013] In the aforementioned intermittent mechanism for raising tiles in a mahjong machine, one side of the movable frame mounting base has a connecting base extending into the tile raising slot. The connecting base is connected to a connecting base located in the tile raising slot via mounting bolts. The connecting base and the connecting base are assembled vertically to form a gear shaft mounting base through which the gear shaft passes. This ensures the stability of the gear shaft within the movable frame mounting base.
[0014] Compared with the existing technology, the advantages of this utility model are:
[0015] 1. The device controls the axial intermittent movement of the movable frame by installing two sector-shaped incomplete gears on the rotating part. The movable frame uses a reciprocating gear rack linkage structure and a lifting plate lifting structure to realize the rising or falling action of the lifting plate. It has a simple structure, is easy to operate, and improves the operating stability of the lifting plate.
[0016] 2. The device uses a reciprocating transmission assembly to connect the rotating part and the movable frame, shortening the transmission distance. At the same time, the sliding guide structure ensures the stable movement of the movable frame, thereby reducing the overall parts and extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS
