Description

Technical Field

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

[0002] As a leading modern entertainment device, the mahjong machine has shined brightly in the mahjong game world with its automated and efficient features. Its working principle cleverly combines the characteristics of electromagnets and magnetism, bringing unprecedented convenience and fun to players. The sticker layer on the back of the mahjong tiles contains substances that can be attracted by magnetism, while the front does not. The tiles rotate with the inclined disc. When the tiles rise to a high position, the tiles with the back facing up are attracted by the magnetic ring on the shuffling barrel and are rotated with the magnetic ring to the conveying groove, where they are stacked into piles by the stacking and pushing motor and pushed away by the link rod. In order to reduce the volume of the mahjong machine, more and more mahjong machines with a rotating lifting mechanism instead of a lifting mechanism are emerging.

[0003] The Chinese invention patent with the publication number CN107773976A disclosed an annular card pushing device and an automatic mahjong machine on March 9, 2018, belonging to the technical field of mahjong machines, which solved the problems of large volume and complex structure of existing mahjong machines. The annular card pushing device of the present invention includes a motor, a base, a turntable, and a card pushing block. The motor is installed on the base, and an annular card pushing groove is provided on the base. The annular card pushing groove is provided with a card inlet and a card outlet. The turntable is located above the base and is driven by the motor to rotate. The turntable drives the card pushing block to perform a card pushing movement in the annular card pushing groove. The use of a rotating card pushing method reduces the card pushing space for mahjong tiles.

[0004] The patentee applied for an invention patent for a card loading mechanism of a mahjong machine on April 26, 2024, with the application number 2024105118060, which discloses an arc-shaped card loading track. The height of this track changes in the height direction, resulting in a change in the height of the mahjong tiles. However, the height of the ordinary card pushing wall remains unchanged. When pushing with the ordinary card pushing wall, it is impossible to push the mahjong tiles stacked on top of each other, and only the upper mahjong tile can be pushed, resulting in incomplete card loading. Summary of the Invention

[0005] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a card pushing mechanism and a mahjong machine, aiming to solve the technical problem that the height change of the card lifting track in the prior art leads to incomplete card pushing.

[0006] To achieve the above purpose, the utility model proposes a card pushing mechanism, which includes a rotatable card pusher and an annular track. The card pusher rotates along the annular track. The conveying groove of the annular track has a height difference, resulting in a change in the height of the object to be conveyed on the conveying groove. A lifting piece that can move up and down is provided on the card pusher.

[0007] Preferably, the annular track is provided with an inlet and an outlet; the annular track includes an inner wall, an outer wall and a bottom surface. The inner wall and the outer wall are arranged on the bottom surface. The side closer to the center of the annular track is the inner wall, and the side farther from the center of the annular track is the outer wall; the side of the bottom surface closer to the outer wall is the outside, and the end of the bottom surface closer to the inner wall is the inside. At least a section of the bottom surface is an inclined surface where the height of the outside is higher than that of the inside.

[0008] Preferably, the pusher includes a rotating wheel and a pushing piece arranged at the end of the rotating wheel, and the pushing piece moves in the conveying groove of the annular track.

[0009] Preferably, a sliding groove is arranged in the pushing piece, a lifting piece is arranged in the sliding groove, and a protrusion is arranged on the lifting piece.

[0010] Preferably, the lifting of the lifting piece is controlled by a guiding device, and one end of the guiding device far away from the lifting piece is hinged on the pusher.

[0011] Preferably, the guiding device includes a guiding plate and a connecting plate arranged below the guiding plate, and a rotating shaft is arranged on the connecting plate.

[0012] Preferably, a guiding groove is arranged on the lifting piece, and one end of the guiding plate close to the lifting piece is arranged in the guiding groove.

[0013] Preferably, a first track protrusion adapted to the change of the bottom surface is arranged on the inner side of the inner wall, so that the lifting piece can move up and down along it.

[0014] Preferably, a second track protrusion adapted to the change of the bottom surface is arranged on the outer side of the inner wall, a guiding piece connected to the second track protrusion is arranged on the lifting piece, and the lifting piece moves up and down along the second track protrusion.

[0015] To achieve the above object, the present invention provides a mahjong machine which uses the above-mentioned pushing mechanism.

[0016] Compared with the prior art, the beneficial effects of a mahjong machine and its pushing mechanism provided by the present invention are as follows:

[0017] 1. The lifting piece of the pusher can move up and down, preventing the mahjong from being pushed to the table due to the change of the position of the mahjong.

[0018] 2. Corresponding track protrusions are arranged on the inner side or the outer side of the annular inclined track. The lifting piece moves along one of the track protrusions, and the height of the lifting piece changes, so that the mahjong will not fail to be pushed during the rotation process, resulting in the mahjong not being able to be pushed to the table.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The present utility model provides a mahjong machine, which includes a card pushing mechanism. The specific card pushing mechanism is as follows:

[0036] Referring to Figures 1-3 , an embodiment of the present utility model provides a card pushing mechanism, which includes a rotatable card pusher 1 and an annular inclined plane track 2. The card pusher 1 rotates along the annular inclined plane track 2. The height difference of the conveying groove of the annular inclined plane track 2 causes the height of the object to be conveyed on the conveying groove to change. A lifting piece 3 that can move up and down is provided on the card pusher 1.

[0037] Referring to Figure 1 and Figure 5, in an alternative embodiment, the annular inclined track 2 is provided with an inlet 24 and an outlet 25. The annular inclined track 2 includes an inner sidewall 21, an outer sidewall 22 and a bottom surface 23. The inner sidewall 21 and the outer sidewall 22 are arranged on the bottom surface 23. The side closer to the center of the annular inclined track 2 is the inner sidewall 21, and the side farther from the center of the annular inclined track 2 is the outer sidewall 22; the side of the bottom surface 23 closer to the outer sidewall 22 is the outer side, and the end of the bottom surface 23 closer to the inner sidewall 21 is the inner side. At least a section of the bottom surface 23 is an inclined surface where the outer height is higher than the inner height.

[0038] Preferably, the bottom surfaces of the inlet 24 and the outlet 25 are horizontal. The height of the outer side of the annular inclined track 2 remains unchanged from the inlet, the height of the inner side gradually and continuously becomes shorter, and then gradually becomes higher to the outlet position. The specific structure below the annular inclined track 2 is as Figure 8 shown. And the height difference reaches the maximum value at the middle position between the inlet 24 and the outlet 25. The mahjong is on the annular inclined track 2 as Figure 9 shown. During the movement of the mahjong, the end closer to the inner sidewall 21 will gradually descend, and the end closer to the outer sidewall 22 will gradually rise, and the mahjong presents an inclined shape. The position where the pusher 1 pushes the cards is relatively close to the inner sidewall 21. The height of the existing pusher 1 does not change. When the height of the mahjong becomes like the above, the pusher 1 can only push the upper mahjong, resulting in the inability to push the lower mahjong to the table. The pusher 1 of the present utility model is provided with a lifting piece 3, and the lifting piece 3 will move up and down along with the annular inclined track 2.

[0039] Refer to Figure 1 and Figure 3 , in an alternative embodiment, the pusher 1 includes a rotating wheel 11 and a pushing piece 12 arranged at the end of the rotating wheel 11. The pushing piece 12 moves in the conveying groove of the annular inclined track 2. The driving wheel 11 of the pusher 1 can be driven by a gear, which is the prior art of the existing pusher 1. The rotation of the driving wheel 11 drives the pushing piece 12 to rotate, and the pushing piece 12 pushes the mahjong to lift the cards.

[0040] Refer to Figure 2 , in an alternative embodiment, a sliding groove 121 is arranged in the pushing piece 12, and a lifting piece 3 is arranged in the sliding groove 121. The lifting piece 3 moves up and down along the sliding groove 121. A protrusion 31 is arranged on the lifting piece 3, and the protrusion 31 pushes the mahjong. In order to prevent the mahjong from getting stuck, the contact part between the protrusion 31 and the mahjong is small.

[0041] Refer to Figure 2, in an optional embodiment, the lifting piece 3 is controlled to lift by a guiding device 4, and one end of the guiding device 4 away from the lifting piece 3 is hinged to the pusher 1. The guiding device 4 is controlled by a track on the annular inclined plane track 2 and drives the lifting of the lifting piece 3. The present utility model describes the guiding structure in two ways.

[0042] The first way:

[0043] Referring to Figure 2 , 3 , 5 and 6, in an optional embodiment, the guiding device 4 includes a guiding plate 41 and a connecting plate 42 arranged below the guiding plate 41, and a rotating shaft 43 is arranged on the connecting plate 42. One end of the guiding plate 41 away from the lifting piece 3 is hinged to the rotating wheel 11. A guiding groove 32 is arranged on the lifting piece 3, and one end of the guiding plate 41 close to the lifting piece 3 is arranged in the guiding groove 32. The up and down lifting of the guiding plate 41 drives the up and down lifting of the lifting piece 3. A first track protrusion 211 adapted to the change of the bottom surface is arranged on the inner side of the inner side wall 21, so that the lifting piece 3 moves up and down along it. The inner side of the inner side wall 21 refers to the side close to the rotation center. The first track protrusion 211 is divided into two sections. The first section starts to slowly decrease from the inlet position and reaches the lowest value at the middle position between the inlet and the outlet. The second section starts to slowly rise from the lowest position of the first section and ends at the outlet position. The structure at the interface between the first section and the second section is as Figure 6 shown. The rotating shaft 43 slowly decreases along the lower part of the first section, and the lifting piece 3 also slowly descends. In the second section, the rotating shaft 43 starts to slowly rise again. As Figure 6 shown only shows the movement tracks of the two ends of the track rotating shaft 43. The first section and the second section can be grooves opened on a convex strip, and the rotating shaft 43 moves in the groove.

[0044] The second way:

[0045] Referring to Figure 4 and Figure 7 , in an optional embodiment, the guiding device 4 includes a guiding plate 41, and one end of the guiding plate 41 away from the lifting piece 3 is hinged to the rotating wheel 11. A second track protrusion 212 adapted to the change of the bottom surface is arranged on the outer side of the inner side wall 21, and a guiding piece 33 connected to the second track protrusion 212 is arranged on the lifting piece 3, and the lifting piece 3 moves up and down along the second track protrusion 212. A rotating shaft can be arranged on the guiding piece 33, a groove is arranged on the second track protrusion 212, and the rotating shaft is arranged on the groove to move, so as to make the lifting piece 3 move up and down. The second track protrusion 212 is also arranged in two sections like the first track protrusion 211, and the structures are the same.

[0046] The lifting of the lifting piece 3 is realized in two ways, so as to avoid the problem of unable to push the cards during the card pushing process.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
