[0030] Reference Figure 1-10, an embodiment of the present invention provides an optimized mahjong machine stacking mechanism, including a slider assembly stacking box 1, a card receiving seat 2 and a swing arm 4; the slider assembly stacking box 1 includes a stacking box cover 11, and a slide rail frame 5, a slider 6 and a driving turntable 7 are provided in the slider assembly stacking box 1; the card receiving seat 2 is provided with a connecting rib 21, a slide groove 22, a card pulling magnet groove 23 and a slide groove 24; the swing arm 4 is provided with a first bearing slide seat 41, a second bearing slide seat 42 and a third bearing slide seat 43; the stacking box cover 11 is covered on the slider assembly stacking box 1, the slide rail frame 5 is installed on the side wall of the slider assembly stacking box 1, and the slider 6 is slidably installed on the slide rail frame 5, The driving turntable 7 is installed between the slider 6 and the stacking box cover 11, the two connecting ribs 21 are located at the lower end of the card holder 2, the sliding groove 22 is located between the two connecting ribs 21, the card pulling magnet groove 23 is located at the center position of the upper surface of the card holder 2, the sliding groove 24 is located at the lower end of the side wall of the card holder 2, the first bearing slide 41 and the third bearing slide 43 are located at the two ends of the rocker 4, the second bearing slide 42 is located in the middle position of the rocker 4 and the first bearing slide 41 and the second bearing slide 42 are located on the same side of the rocker 4, the card holder 2 is an injection molded part, and the connecting rib 21 slides in the card holder slide shaft seat 3.
[0031] The cam 7 is mounted on the side wall of the slider assembly stacking box 1, and the driving turntable 7 is mounted in the slider assembly stacking box 1. The three bearing slides on the rocker arm 4 are respectively mounted on the card holder 2, the driving turntable 7 and the stacking box cover 11. The rotation of the driving turntable 7 drives the movement of the rocker arm 4, thereby driving the card holder 2 to rise and fall. The injection molding design of the card holder 2 has changed the industry's use of two φ6mm iron shafts for pre-embedding. After optimization, the two shafts are directly injection molded to fix the position of the connecting rib 21 to ensure the reliability of up and down sliding, saving the cost of iron shafts (turning, rounding, chrome plating, knurling) and the pre-embedding labor of injection molding. The card holder 2 has no iron shaft, which can make the position of the card pulling magnet more reasonable, and the card holder 2 is more stable and neat when playing cards.
[0032] In one embodiment, two slide rail mounting openings 14, limiting ribs 16 and stacking box screw holes 15 are provided on the rear side wall of the slider assembly stacking box 1. The two slide rail mounting openings 14 are close to one side of the card holder 2, and the limiting ribs 16 are located in front of the slide rail mounting openings 14. A card holder slide shaft seat 3 is provided on the side wall of the slider assembly stacking box 1, and an intermediate groove 31 is provided in the middle of the card holder slide shaft seat 3. The slide rail frame 5 includes a slide rail frame slide rail 51, a clamping foot 52, a slide rail frame screw hole 53 and an oil guide groove 54.

[0033] It can be understood that when installing, first insert the slider slot 61 into the slide rail 51 of the slide rail frame, then press the assembled slide rail frame 5 into the slide rail frame installation port 14 of the slider assembly stacking box 1, and then push it forward. The slide rail frame screw hole 53 and the stacking box screw hole 15 are aligned and fixed with an M4 self-tapping screw to ensure that the operation noise is low, the wear rate is low, the service life is long, and the horizontal push action is more stable and reliable. The setting of the middle groove 31 ensures the up and down sliding space of the connecting rib 21. The front end of the slide rail frame 5 has an upward protrusion. The card foot 52 is inserted into the slide rail frame mounting opening 14 and pushed forward to be combined with the slider assembly stacking box 1, and an M4 self-tapping screw is added to fix it. The two limiting ribs 16 in front of the slide rail frame mounting opening 14 can prevent the sliding position change caused by the injection deformation and shrinkage of the front end part of the slide rail frame 5, thereby ensuring that the slide rail 51 of the slide rail frame here is still in a parallel state, ensuring the stable and reliable sliding and pushing of the slider 6. When the slide rail frame 5 and the slider 6 are combined, grease can be retained in the oil guide groove 54, which helps the slider 6 to slide smoothly in the slide rail frame 5.

[0035] Understandably, the card-type capacitor installation position 12 does not require screws to fix, and can be compatible with motor capacitors of the same model and specifications but different appearances from various manufacturers on the market. The rocker arm 4 is integrated and is injection molded in one step using high-strength wear-resistant plastic. It can effectively solve the many problems of the original sheet metal parts fixed with screws and the iron sleeve installed with big-head screws, such as running noise, wear of the iron sleeve and the round wheel, slider, sheet metal deformation, screw loosening, and the gaps between various parts are difficult to fix. The stacking action is affected by the changes in the gaps at the three points of the rocker arm 4 and many other problems. The integrated rocker arm 4 has low running noise, is wear-resistant at three points, saves assembly labor, reduces material costs, reduces debugging standards, and significantly increases stability and reliability.
[0036] An embodiment of the present invention further provides a mahjong machine, which includes the optimized mahjong machine stacking mechanism.
[0037] In the mahjong machine of the present invention, the card holder 2 is designed by injection molding, which changes the industry's practice of pre-embedding two φ6mm iron shafts. After optimization, the two shafts are directly injection molded to connect the ribs 21 to fix their positions to ensure the reliability of sliding up and down, saving the cost of the iron shafts (turning, rounding, chrome plating, knurling) and the pre-embedding labor of injection molding. The card holder 2 has no iron shaft, which can make the position of the card pulling magnet more reasonable. The card holder 2 is more stable and neat when playing cards. The sliding gap of the slider assembly is small, the operating noise is small, the wear rate is low, the service life is long, the horizontal push action is more stable and reliable, and the card-type capacitor installation position 12 does not need to be Fixed with screws, it is compatible with motor capacitors of the same model and specifications but different shapes from various manufacturers on the market.

It can effectively solve many problems of the original sheet metal parts fixed with screws and iron sleeves installed with big-head screws, such as running noise, wear of the iron sleeve and round wheel, slider, sheet metal deformation, screw loosening, and difficulty in fixing the gaps between various parts. The stacking action is affected by the changes in the gaps between the three points of the pendulum arm 4 and many other problems. The integrated pendulum arm 4 has low running noise, is wear-resistant at three points, saves assembly labor, reduces material costs, lowers debugging standards, and significantly increases stability and reliability.
