[0001] The utility model relates to the technical field of entertainment equipment, and specifically relates to a lifting plate structure of a rotary mahjong machine. Background Art

[0002] As a relatively common entertainment equipment at present, mahjong machines are liked by people in many places to play mahjong for entertainment during their free time. However, the existing rotary mahjong machines have complex structures, and multiple structures and multiple motor controls are required for actions such as stacking cards, dealing cards, and lifting cards, resulting in high production costs, cumbersome installation methods, and reduced production efficiency. At the same time, for the lifting plate, the lifting plate is installed on the surface of the mahjong machine, and its tilting and lifting are realized by a separate motor control for the lifting action of the lifting plate. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a lifting plate structure of a rotary mahjong machine, which can reduce the use of motors and cancel the placeholder notch provided for the card-pushing head of the mahjong machine at the end of the lifting plate, so that the number of motors of the mahjong machine is reduced, and the lifting plate structure is complete and beautiful.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a lifting plate structure of a rotary mahjong machine, including a lifting plate and a fork. One end of the lifting plate is rotationally connected to the tabletop of the mahjong machine, and the other end is a free lifting end. When the lifting plate is horizontal, the upper surface of the lifting plate is flush with the tabletop of the mahjong machine. The fork includes a driving piece, a rotating cylinder, and a shifting rod. The rotating cylinder is rotatably installed in the mahjong machine. The shifting rod is installed on the side surface of the rotating cylinder and is located below the lifting plate. The driving piece is installed at the upper end of the rotating cylinder. An inclined downward chute is provided on the lower side surface of the lifting plate corresponding to the shifting rod, and the end of the shifting rod away from the rotating cylinder can be placed in the chute.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-9 , the present utility model provides a technical solution: a card-lifting plate structure of a rotary mahjong machine, including a card-lifting plate 1 and a fork. One end of the card-lifting plate 1 is rotatably connected to the tabletop of the mahjong machine, and the other end is a free lifting end. When the card-lifting plate 1 is horizontal, the upper surface of the card-lifting plate 1 is flush with the tabletop of the mahjong machine. The fork includes a driving piece, a rotating cylinder, and a pushing rod 4. The rotating cylinder is rotatably installed in the mahjong machine. The pushing rod 4 is installed on the side surface of the rotating cylinder and is located below the card-lifting plate 1. The driving piece is installed at the upper end of the rotating cylinder. An inclined downward sliding groove 5 is provided on the lower side surface of the card-lifting plate 1 corresponding to the pushing rod 4. The end of the pushing rod 4 away from the rotating cylinder can be placed in the sliding groove 5.

[0025] By pushing the driving piece, the driving piece drives the rotating cylinder to rotate, and the rotating cylinder drives the pushing rod 4 to move, so that the pushing rod 4 slides in the sliding groove 5. Since the sliding groove 5 is an inclined structure, when the pushing rod 4 slides in the sliding groove 5, the card-lifting plate 1 will descend or the pushing rod 4 will move to lift the card-lifting plate 1. By reducing the motor driving form, the complexity of the equipment structure and the cost of the equipment components are reduced.

[0026] In actual use, a protrusion 9 can be provided on the card-pushing rod, and the protrusion 9 is positioned and matched with the driving piece, so that the card-pushing rod can push the driving piece to rotate through the protrusion 9, so as to realize the rotation and reset of the rotating cylinder.

[0027] There are two levers 4, which are arranged up and down on the rotating drum and are also arranged in a V-shaped fork. Due to the compact structure inside the mahjong machine, the arrangement of one lever 4 may result in a limited height reduction of the card-raising board 1. Therefore, through the design of the upper and lower levers 4, after the upper lever 4 completes the shifting stroke, the lower lever 4 is just located at the opening of the slide groove 5 to continue to shift the card-raising board 1, so that the card-raising board 1 continues to descend to meet the low-position requirement.

[0028] In order to realize the driving and resetting functions of the driving plate, a variety of implementation methods are provided, as follows:

[0029] Example 1

[0030] like Figures 1-4 As shown, the driving plate includes a rotating plate 2, a guide plate 11 and a limiting protrusion 12. One end of the rotating plate 2 is connected to the rotating drum 10, and the guide plate 11 is arranged at the other end of the rotating plate 2, and the side surface of the rotating plate 2 is located on the lower surface of the guide plate 11. The limiting protrusion 12 is arranged on the lower surface of the guide plate 11 and is located at the end away from the rotating plate 2. The side of the limiting protrusion 12 facing the side of the rotating plate 2 is a limiting guide surface 13.

[0031] The limiting guide surface 13 of the limiting protrusion 12 facing one side of the rotating plate 2 is composed of a continuously connected arc convex surface 14 and a smooth plane 15, and the arc convex surface 14 is arranged at one end close to the side of the rotating plate 2.

[0032] When the card-pushing rod is pushing the mahjong tiles into the slot, the moving position of the card-pushing rod is between the side lengths of the rotating plate 2; when the card-pushing is completed and the mahjong tiles in the slot need to be pushed onto the card-lifting plate 1, the card-pushing rod first rotates counterclockwise, and the protrusion 9 on the card-pushing rod touches the limiting guide surface 13 of the limiting protrusion 12, so that the protrusion 9 slides between the limiting guide surface 13, and the limiting protrusion 12 drives the guide plate 11 and the rotating plate 2 to rotate counterclockwise. When the protrusion 9 is separated from the limiting protrusion 12, or the protrusion 9 and the limiting protrusion 12 have moved a preset sliding distance, the card-pushing rod rotates clockwise. The card pushing rod rotates so that the protrusion 9 on the card pushing rod is located on the back side of the rotating plate 2, and then the card pushing rod continues to rotate clockwise to drive the rotating plate 2 to rotate counterclockwise, so that the rotating plate 2 drives the rotating drum 10 to rotate, and the card lifting plate 1 is lowered and docked with the card slot; then the card pushing rod rotates counterclockwise to push the mahjong tiles in the card slot onto the card lifting plate 1, and after completing the card pushing, it continues to rotate counterclockwise, and the protrusion 9 on the card pushing rod contacts the positive side of the rotating plate 2, and pushes the rotating plate 2 to rotate clockwise, so that the rotating plate 2 drives the rotating drum 10 to rotate, and the card lifting plate 1 is lifted, completing the action of lifting the mahjong tiles to the mahjong table.

[0033] Example 2

[0034] like Figures 5-8As shown, the driving plate includes a rotating plate 2 and a return spring 3. One end of the rotating plate 2 is connected to the rotating drum, and the other end of the rotating plate 2 is provided with a return spring 3. One end of the return spring 3 is arranged toward the outside and extends out of the side of the rotating plate 2 for a distance.

[0035] When the pusher is in the action of pushing the mahjong tiles into the slot, the moving position of the pusher is between the side lengths of the rotating plate 2. When the pushing of tiles is completed and the tiles in the slot need to be pushed onto the lifting plate 1, the pusher first rotates counterclockwise, so that the projection 9 on the pusher touches the return spring sheet 3, causing the return spring sheet 3 to rotate clockwise until it disengages from the projection 9. At this time, the return spring sheet 3 loses the resistance of the projection 9 and immediately rotates counterclockwise back to its original position. At this time, the projection 9 is located on the back side of the return spring sheet 3, and the pusher rotates clockwise accordingly, driving the projection 9 to push the return spring sheet 3. The back side of the spring sheet 3 then drives the rotating plate 2 to rotate counterclockwise, and drives the lifting plate 1 to descend through the lever 4. When the lifting plate is lowered into place, the pushing rod immediately rotates counterclockwise to push the mahjong tiles in the card slot onto the lifting plate 1, and after completing the pushing of the tiles, it continues to rotate counterclockwise, and makes the protrusion 9 on the pushing rod contact the positive side of the rotating plate 2, and pushes the rotating plate 2 to rotate clockwise, so that the rotating plate 2 drives the rotating drum 10 to rotate, realizes the lifting of the lifting plate 1, completes the action of raising the mahjong tiles to the mahjong table, and the pushing rod stops accordingly, and its stopping position is set to make the protrusion 9 located in front of the return spring sheet 3 at the end of the rotating plate 2.

[0036] Example 3

[0037] In order to limit the rotation angle of the card lifting plate and the rotating drum and avoid collision damage of related structures caused by excessive rotation, a positioning plate 8 is provided on the lower side of the card lifting plate 1 corresponding to the end of the slide groove 5, and the upper lever 4 cooperates with the positioning plate 8. When the card lifting plate 1 is raised and is in a horizontal state, the upper lever 4 is located at the positioning plate 8. Through the resistance of the upper lever 4 to the positioning plate 8, the card lifting plate 1 can be kept in a horizontal state continuously, and the rotating plate 2 is prevented from moving due to the resistance of the pushing end of the pushing mechanism.

[0038] A limit stopper 6 is arranged at the position of the lever 4 corresponding to the lower side of the rotating drum in the mahjong machine. After the card raising board 1 returns to its original position, the lever 4 at this position can abut against the limit stopper 6.

[0039] A through slot 7 is provided in the mahjong machine at a position corresponding to the lever 4 on the upper side of the rotating drum, and the lever 4 at this position passes through the through slot 7 and cooperates with the slide slot 5.

[0040] In order to prevent the rotating drum or rotating plate 2 from rotating excessively, the limit stopper 6 is provided so that after the card raising is completed, the lower lever 4 reaches the limit position to prevent excessive rotation.

[0041] To increase the up-and-down lifting stroke of the card-lifting plate 1, by setting the length of the through slot 7, the upper lifting rod 4 can move within the length direction of the through slot 7, and the through slot 7 also has the function of structural stability. When the card-lifting plate 1 is in a horizontal state, its through slot 7 can also apply a stable force to the upper lifting rod 4 to ensure the structural stability between the upper lifting rod 4 and the positioning plate 8.

The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
