Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a card pushing mechanism and a mahjong machine. Background Art

[0002] Mahjong machines, a leading modern entertainment device, have made a splash in the mahjong world thanks to their automation and efficiency. Their operating principle cleverly combines the properties of electromagnets and magnetism, bringing unprecedented convenience and enjoyment to players. The back of the tiles contains a magnetically attractive material, while the front does not. The tiles rotate on a tilted disc. When the tiles reach a high point, the back-facing tiles are attracted by the magnetic rings on the shuffling drum. As the magnetic rings rotate, they are transported to a conveyor chute, where they are stacked by a stacking motor and then pushed away by a chain rod. To reduce the size of mahjong machines, the lifting mechanism has been replaced by a rotary mechanism, and more and more mahjong machines are adopting this mechanism.

[0003] Chinese invention patent publication number CN107773976A, issued on March 9, 2018, discloses a circular card-pushing device for an automatic mahjong machine and the machine itself. This invention addresses the issues of existing mahjong machines, such as the large size and complex structure. The circular card-pushing device comprises a motor, a base, a turntable, and a card-pushing block. The motor is mounted on the base, which is provided with a circular card-pushing trough with a card inlet and a card outlet. The turntable is located above the base and is driven to rotate by the motor. The turntable drives the card-pushing block to push cards within the circular card-pushing trough. The rotary card-pushing method reduces the space required to push mahjong tiles.

[0004] The patent owner applied for an invention patent for a mahjong machine loading mechanism on April 26, 2024, with application number 2024105118060, which discloses an arc-shaped loading track. The track will change in the height direction, causing the height of the mahjong to change, while the height of the ordinary pushing wall is unchanged. When pushing through the ordinary pushing wall, it is impossible to push the mahjong stacked together, and only the upper mahjong can be pushed, resulting in the inability to completely load the cards. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a card pushing mechanism and a mahjong machine, which aims to solve the technical problem in the prior art that the height change of the card raising track leads to the inability to completely push the cards.

[0006] To achieve the above-mentioned purpose, the utility model proposes a card pushing mechanism, including a rotatable card pusher and a card track shell, the card track shell is provided with an annular inclined track, and the card pusher rotates along the annular inclined track; an annular track seat with varying height is provided in the card track shell; the card pusher rises and falls along the annular track seat during the card pushing process.

[0007] Preferably, the card pusher includes a card pushing head, a connecting rod connected to the card pushing head, and a lifting rod for controlling the lifting.

[0008] Preferably, a movable shaft is provided at the bottom of the lifting rod, and a track groove is provided on the side wall of the annular track seat; the movable shaft moves along the track groove.

[0009] Preferably, the lifting rod is connected to a limiting seat, the limiting seat is provided with a limiting groove, and the lifting rod is provided with a convex piece, and the convex piece is lifted and lowered along the limiting groove.

[0010] Preferably, the track groove is spiral-shaped, and first slowly descends and then slowly rises from the corresponding position of the card inlet to the card outlet of the annular inclined track.

[0011] Preferably, the card pusher is driven to rotate by a transmission mechanism, and the transmission mechanism is controlled by a motor.

[0012] Preferably, the transmission mechanism includes a central pinion, a plurality of intermediate gears meshing around the central pinion, and an inner gear ring arranged outside the intermediate gears.

[0013] To achieve the above object, the utility model provides a mahjong machine, which uses the above-mentioned card pushing mechanism.

[0014] Compared with the prior art, the card pushing mechanism provided by the present invention has the following beneficial effects:

[0015] 1. The tile pusher can move up and down along the circular track seat, and its height changes as the center of gravity of the mahjong changes, preventing the mahjong from being unable to be pushed to the tile loading position.

[0016] 2. The center pinion drives the middle gear, and the outer side of the middle gear is meshed with an internal gear. The internal gear pushes the pusher to provide higher output torque and extend the service life of the motor.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. "Several" means one or more, unless otherwise clearly and specifically defined.

[0032] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] The present invention provides a mahjong machine including a card pushing mechanism. The specific card pushing mechanism is as follows:

[0034] See Figure 1 An embodiment of the utility model provides a card pushing mechanism, including a rotatable card pusher 1 and a card track shell 2, wherein the card track shell 2 is provided with an annular inclined track 3, and the card pusher 1 rotates along the annular inclined track 3; an annular track seat 4 with varying height is provided in the card track shell 2; during the card pushing process, the card pusher 1 rises and falls along the annular track seat 4.

[0035] The annular inclined track 3 is provided with an inlet and an outlet. The annular inclined track 3 includes an inner sidewall, an outer sidewall, and a bottom surface. The bottom surface is provided with an inner sidewall and an outer sidewall. The side closer to the center of the annular inclined track 3 is the inner sidewall, and the side farther from the center of the annular inclined track 3 is the outer sidewall. The side of the bottom surface closer to the outer sidewall is the outer side, and the end of the bottom surface closer to the inner sidewall is the inner side. At least one section of the bottom surface is an inclined surface with an outer side height higher than the inner side height.

[0036] Preferably, the bottom surfaces of the inlet and outlet are horizontal. The height of the outer side of the annular inclined track 3 is constant from the inlet, and the height of the inner side gradually decreases, and then gradually increases to the outlet position. The specific structure below the annular inclined track 3 is as follows: Figure 8 As shown. And the height difference reaches the maximum at the middle position between the inlet and the outlet. Figure 9 As shown. During the movement of the mahjong, the end close to the inner wall will slowly drop, and the end close to the outer wall will slowly rise, and the mahjong will appear tilted. The position of the card pusher 1 pushing the cards is relatively close to the inner wall. The height of the existing card pusher 1 does not change. When the height of the mahjong becomes as described above, the card pusher 1 can only push the mahjong placed on top, resulting in the mahjong below being unable to be pushed to the table. The card pusher 1 of the utility model is provided with a card pusher 1 whose height can change, and the card pusher 1 can move up and down along the annular inclined track 2.

[0037] See Figure 7 In an optional embodiment, the card pusher 1 includes a card pushing head 11, a connecting rod 12 connected to the card pushing head 11, and a lifting rod 13 for controlling lifting. The card pushing head 11 moves in the annular inclined track 3 to push cards.

[0038] See Figure 6 and Figure 7 In an optional embodiment, a movable shaft 14 is provided at the bottom of the lifting rod 13, and a track groove 41 is provided on the sidewall of the annular track seat 4; the movable shaft 14 moves along the track groove 41. The movable shaft 14 can be a bearing and rolls during movement in the track groove 41, reducing friction and extending service life.

[0039] See Figure 2 、 Figure 3 and Figure 7 In an optional embodiment, the lifting rod 13 is connected to a limit seat 5, which is provided with a limit slot 51. The lifting rod 13 is provided with a protrusion 131, which is raised and lowered along the limit slot 51. The cooperation between the limit slot 51 and the protrusion 131 makes the lifting rod 13 more stable and along a fixed track.

[0040] See Figure 5 and Figure 6 In an optional embodiment, the track groove 41 is spiral, initially descending and then ascending from the corresponding position of the annular inclined track 3 between the card inlet and the card outlet. The spiral shape of the track groove 41 matches the trajectory of the annular inclined track 3. When the card inlet and card outlet are in the same position, the pusher 11 is at its highest position. When moving from the card inlet to the card outlet, the pusher 11 first descends and then ascends, ensuring that a tile is always pushed.

[0041] See Figure 4 In an optional embodiment, the card pusher 1 is driven to rotate by a transmission mechanism 6, and the transmission mechanism 6 is controlled by a motor. The transmission mechanism 6 includes a central pinion 61, a plurality of middle gears 62 meshing around the central pinion 61, and an internal gear 63 arranged on the outside of the middle gear 62. There are preferably three middle gears, and the middle gears 62 are evenly distributed around the central pinion 61. The motor drives the central pinion 61 to rotate, and the central pinion 61 drives the middle gear 62 to rotate, and the middle gear 62 drives the internal gear 63, and the internal gear 63 drives the card head 11. During the lifting process of the lifting rod 13, it will rise and fall along the track groove 41, thereby realizing the height change during the card pushing process.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
