Description

Technical Field

[0001] This utility model relates to the technical field of mahjong machines, and in particular to a tile pushing and lifting linkage mechanism for a mahjong machine. Background Technology

[0002] The process of a rotating tile-lifting mahjong machine raising the mahjong tiles to the table involves first stacking the tiles vertically in pairs within the tile slots, then pushing them onto the table via a pusher rod. While the pusher rod is pushing the tiles, the lifting plate is tilted to facilitate the tiles' entry onto the table. After the tiles reach the table, the lifting plate rotates to maintain alignment with the table surface. However, currently, the lifting plate and the pusher rod are controlled by separate motors, and having too many motors increases the complexity of control.

[0003] Chinese invention patent CN111450519A, published on April 28, 2020, discloses an integrated linkage tile-lifting mechanism for a mahjong machine. The mechanism includes a tile-pushing component, a tile-lifting component, and a driving component. The tile-pushing component includes a tile-pushing groove and a tile-pushing assembly. The tile-lifting component includes a tile-lifting plate and a tile-lifting assembly. The annular tile-pushing groove includes a tile inlet and a tile outlet. The tile-lifting plate, with one end connected to the tile outlet, extends to the tabletop. The driving component includes a gear system and a driving element. The gear system includes a driving gear, a driven gear system, and an incomplete gear with a notch. Both the driven gear system and the incomplete gear mesh with the driving gear. When the notch of the incomplete gear, which drives the tile-pushing assembly, meshes with the driving gear, the tile-lifting assembly, driven by the driven gear system, pushes the tile-lifting plate to move until it is flush with the tabletop. This patent achieves the switching between different states of the tile-pushing and tile-lifting rods through the incomplete gear. However, over time, the gears may not mesh properly, leading to interference, abnormal noise, or even jamming.

[0004] Therefore, it is necessary to propose a method that does not use incomplete gears to switch between the different states of the push lever and the lift lever. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0028] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0029] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The rotating tile-feeding mechanism of a mahjong machine consists of identical mechanisms located at each of the four corners. The rotating pusher lever pushes the mahjong tiles from the storage channel along the lifting plate onto the tabletop, where the lifting plate then rises until it is flush with the table surface. Example 1:

[0032] See Figures 1-8This utility model embodiment provides a tile-pushing and tile-lifting linkage mechanism for a mahjong machine, including a tile-lifting plate 1, a tile path 2, and a tile-pushing rod 3. The tile-pushing rod 3 rotates to push the mahjong tiles along the tile path 2 onto the tile-lifting plate 1. The end of the tile-lifting plate 1 closest to the tile path 2 can rotate along the side of the tile-lifting plate 1 away from the tile path 2. A track 31 is provided at the bottom of the tile-pushing rod 3, and a gear ring 32 is provided on the tile-pushing rod 3. The gear ring 32 meshes with a driven gear 4. The driven gear 4 moves along the track 31, and a linkage rod 5 is connected to the driven gear 4. The track 31 includes a translation track 311. The movement of the driven gear 4 within the translation track 311 drives the linkage rod 5 to translate, causing the tile-lifting plate 1 to rotate. The tile pushing and lifting are achieved through the forward and reverse rotation of the tile-pushing rod 3. Sometimes, due to space limitations, the base of the mahjong machine does not allow the tile-pushing rod 3 to rotate 360 ​​degrees, but forward and reverse rotation eliminates the need for 360 degrees.

[0033] The tile path includes an entry point and an exit point. The entry point is where the mahjong tile enters the path (a), and the exit point is where the mahjong tile moves from the path to the tile-raising board (c). From position (a) to position (c), the push rod 3 rotates counter-clockwise; when returning from position (c) to position (a), it rotates clockwise.

[0034] It also includes a drive gear 6 mounted on the lane 2, which is driven by a motor and meshes with a driven gear 4. The entire process is controlled by a single motor capable of forward and reverse rotation.

[0035] The card pusher 3 includes a disc 31 and a card pusher head 32 disposed on the outer side of the disc 31. The center of the disc 31 is rotatably disposed on the card track 2. The disc 31 is rotatably disposed on the base, and the card pusher head 32 rotates along the card track 2.

[0036] The track 31 comprises an inner track 313, an outer track 314, and a translation track 311 forming a ring. Both ends of the inner track 313 and the outer track 314 are connected via the translation track 311. The toothed ring 32 is an outer toothed ring distributed along the track 31. The height of the card-lifting plate can be switched on the translation track 311, and there is a delay when moving at position CD, meaning the motor rotates, but the card-pushing lever 3 does not rotate.

[0037] The sign track 2 is mounted on the sign track housing 7. The driving gear 6 is a gear ring with an internal gear. A fixing block 61 is provided inside the driving gear 6, and a driven gear 4 is provided on the fixing block 61. The gear ring rotates together with the motor, and the fixing block 61 rotates together with the gear ring. The driven gear 4 is located at a non-central position on the gear ring. The sign track housing 7 is provided with a through groove 71, and the driving gear 6 is provided in the through groove 71. The driven gear and the gear ring mesh with each other, and can drive the driven gear 4 to rotate during the rotation of the gear ring, without interference in various states. Example 2:

[0038] The linkage used in Example 1 has the following specific structure:

[0039] The linkage 5 includes a V-shaped rod 51, a rocker arm 42, and a lifting track seat 43. One end of the V-shaped rod 51 is connected to the driven gear 4, and the other end is disposed in the through groove 71 and connected to the rocker arm 42. The rocker arm 42 is connected to the lifting track seat 43, and the lifting track seat 43 is connected to the lifting plate 1. The driven gear 4 is provided with a groove 41, and the V-shaped rod 51 is provided with a slot 511. The groove 41 and the slot 511 cooperate to engage the driven gear 4 and the V-shaped rod 51.

[0040] Specifically, the V-shaped rod 51 appears V-shaped when viewed from the top and bottom views, but to conform to reality, the two sides are not necessarily at the same height. A rocker arm 42 is provided on one side of the V-shaped rod 51. One end of the V-shaped rod 51 is engaged with the driven gear 4, and the other end is connected to a rocker arm. The V-shaped rod 51 is confined to the base and can only move horizontally, driving the rocker arm 42 to rotate during this movement. The lifting track seat 43 is connected to the lifting plate 1, and the lifting track seat is roughly diagonally oriented. A pivot is provided on the side of the lifting plate 1 away from the plate path, and the side closer to the plate path can rotate along the other end. The rocker arm's movement on the lifting track seat causes the lifting plate 1 to rotate.

[0041] Specific work process (in) Figure 1 (as the direction of rotation determination for push lever 3)

[0042] The push lever 3 can switch between clockwise and counterclockwise rotation.

[0043] by Figure 6 For example, the pusher lever 3 can switch between three positions: a, b, and c.

[0044] At position b, during the stacking phase, the mahjong tiles are stacked one above the other inside the tile path.

[0045] At this time, driven gear 4 is in position B, and the lifting plate is in its highest position.

[0046] The transition from position b to position a is the card-pushing preparation stage. At this time, the driven gear 4 moves from position B to position A, and the card-raising plate descends from the highest position to the lowest position, allowing the mahjong tiles to be moved onto the card-raising plate.

[0047] The movement from position b to position c is the preparation stage for pushing the tiles. During this time, the driven gear moves from position A to position D, first passing through position C. In this situation, when the tile pusher 3 is between positions A and C, it rotates along with the motor. When the movement is between positions C and D, the motor rotates while the tile pusher 3 does not rotate, and the tile lifting plate rotates from its lowest point to rise onto the table, thus lifting the mahjong tiles.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
