Description

Technical Field

[0001] This utility model relates to the field of mahjong machines, and in particular to a mahjong machine, a flat-push tile blocking mechanism, and a movable baffle installation structure. Background Technology

[0002] Mahjong is widely enjoyed by the public as a recreational activity and has also been recognized as a competitive sport. Traditional mahjong machines place the tiles parallel to the edges of the table after they are raised, and the tiles are very close to the edge, resulting in an unreasonable arrangement. Before drawing a tile, players need to manually move the tiles forward and diagonally to a suitable position. During this process, the tiles are prone to tipping over, causing inconvenience to the players.

[0003] The prior art disclosed in CN219149199U includes a mahjong machine, a flat-push tile blocking mechanism, and a movable baffle mounting structure. The flat-push tile blocking mechanism includes a tile blocking frame for blocking the mahjong tiles on the tile-supporting plate of the flat-push tile-feeding device from moving inward. The tile blocking frame is located inside the tile-supporting plate, and an outer tile blocking part extends outward from the tile blocking frame. The outer tile blocking part has an opening above the tile-bearing block of the tile-pushing device for the tile-pushing head of the tile-pushing device to slide through. It also includes a movable baffle, which is installed on the outer tile blocking part in a way that allows it to flip and swing up and down. The movable baffle is driven by the tile-pushing head or the tile-supporting plate to flip and swing up and down, and is reset by an elastic element.

[0004] In the prior art, the upper part of the card block frame and the upper part of the outer card block section are connected together, and the movable baffle is installed on the connection between the card block frame and the outer card block section. This makes the positioning accuracy requirements of the card block frame, the movable baffle, the card support plate and other components of the mahjong machine high, and makes the assembly, disassembly and tabletop of the mahjong machine prone to interference. Utility Model Content

[0005] To address the high positioning requirements in the assembly of mahjong machines in existing technologies, the present invention aims to provide a mahjong machine, a flat-push blocking mechanism, and a movable baffle installation structure. The flat-push blocking mechanism is a separate unit installed on the tabletop, thereby reducing the assembly difficulty of the mahjong machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a movable baffle installation structure for a mahjong machine, wherein the movable baffle is hinged to the bottom of the tabletop; the pusher head can drive the movable baffle to rotate and swing up and down to an avoidance state; an elastic element is provided between the movable baffle and the tabletop, and the elastic element can drive the movable baffle to return to the flat-push blocking state; in the flat-push blocking state, the movable baffle is limited and fixed by the tabletop, and the movable baffle can restrict the movement of mahjong tiles from the movable baffle to the pusher head.

[0007] Preferably, the movable baffle is hinged to the mounting base, which is fixedly installed on the bottom of the desktop panel.

[0008] Preferably, in the flat-push blocking state, the movable blocking plate is fixed in place by the mounting seat.

[0009] Preferably, the movable baffle has a protruding limit part. When the movable baffle is in the flat-push baffle state, the torsion spring drives the limit on the movable baffle to press against the outer wall of the mounting base.

[0010] Preferably, the elastic element includes a torsion spring, the movable baffle is mounted on the mounting base via a hinge shaft, the torsion spring is sleeved on the hinge shaft, one leg of the torsion spring abuts against the mounting base, and the other leg of the torsion spring abuts against the movable baffle; the torsion spring gives the movable baffle a tendency to maintain the flat-push baffle state.

[0011] Preferably, the bottom of the mounting base is provided with an opening, and the top of the movable baffle has a protruding hinge portion. The hinge portion extends into the opening of the mounting base and is rotatably mounted on the mounting base via a hinge shaft. The end of the hinge shaft is connected to two opposing inner walls inside the opening, and the two opposing inner walls on the opening abut against the side of the hinge portion.

[0012] Preferably, the hinge has a notch, the inner wall of the mounting base opening has a mounting groove, the torsion spring is located in the notch of the hinge, one leg of the torsion spring extends into the mounting groove in the mounting base opening, and the other leg of the torsion spring abuts against the movable baffle.

[0013] Preferably, the two torsion springs are arranged symmetrically.

[0014] A flat-push tile-blocking mechanism for a mahjong machine includes the aforementioned movable baffle mounting structure for a mahjong machine; it also includes a tile-blocking frame for preventing mahjong tiles on a tile-supporting plate of a flat-push tile-loading device from moving inward, the tile-blocking frame being located inside the tile-supporting plate; it further includes a first tile-blocking frame and a second tile-blocking frame, both of which are fixed to the bottom of the tabletop, the second tile-blocking frame and the first tile-blocking frame cooperating to form a channel for the tile-pushing head of the tile-pushing device to slide through; a movable baffle is disposed between the second tile-blocking frame and the first tile-blocking frame, the first tile-blocking frame being located between the movable baffle and the tile-blocking frame.

[0015] A mahjong machine includes the aforementioned flat-push tile-blocking mechanism for a mahjong machine.

[0016] The beneficial effects of the technical solution of this utility model are as follows: the movable baffle is directly installed on the tabletop, which makes the installation structure of the movable baffle simpler. Furthermore, due to the elimination of the structure between the baffle frame and the tabletop, the movable baffle can be made taller, which can accommodate larger mahjong tiles.

Example

[0032] like Figures 1 to 7The diagram shows a movable baffle mounting structure for a mahjong machine. The movable baffle 802 is hinged to the bottom of the tabletop 10. The pusher head can drive the movable baffle 802 to rotate and swing up and down to an avoidance state. An elastic element is provided between the movable baffle 802 and the tabletop 10, which can drive the movable baffle 802 to return to the flat-push blocking state. In the flat-push blocking state, the movable baffle 802 is in a vertical state and is fixed in place by the tabletop 10. The movable baffle 802 can restrict the movement of mahjong tiles from the movable baffle 802 to the pusher head.

[0033] With this configuration, the active baffle 802 of this application is independently installed on the tabletop 10, which makes the assembly of the mahjong machine more flexible and reduces the positioning requirements of each component of the mahjong machine.

[0034] In this embodiment, as Figures 1 to 3 As shown, the movable baffle 802 is hinged to the mounting base 805, and the mounting base 805 is fixedly installed on the bottom of the desktop panel 10.

[0035] In this embodiment, as Figure 4 As shown, when the movable baffle 802 is in the flat-push baffle state, it is fixed in place by the mounting base 805. Specifically, the movable baffle 802 has a protruding limiting part 8023. When the movable baffle 802 is in the flat-push baffle state, the elastic element drives the limiting part on the movable baffle 802 to abut against the outer wall of the mounting base 805, thereby limiting the angle between the movable baffle 802 and the mounting base 805.

[0036] In this embodiment, as Figure 4 and Figure 5 As shown, the bottom of the mounting base 805 has an opening 8052, and the top of the movable baffle 802 has a protruding hinge portion 8021. The hinge portion 8021 extends into the opening 8052 of the mounting base 805 and is rotatably mounted on the mounting base 805 via a hinge shaft 806. The end of the hinge shaft 806 is connected to two opposing inner walls on the opening 8052, and the two opposing inner walls on the opening 8052 abut against the side of the hinge portion 8021. A limiting portion 8023 is provided on the hinge portion 8021. This configuration restricts the axial movement of the movable baffle 802 along the hinge shaft 806, ensuring the stability of the movable baffle 802.

[0037] In this embodiment, as Figure 4 and Figure 5As shown, a notch 8022 is provided on the hinge portion 8021, and a mounting groove 8052 is provided on the inner wall of the opening 8052 of the mounting base 805; the elastic element includes a torsion spring 807, which is sleeved on the hinge shaft 806. The torsion spring 807 is located in the notch 8022 of the hinge portion 8021, one leg of the torsion spring 807 extends into the mounting groove 8052 in the opening 8052 of the mounting base 805, and the other leg of the torsion spring 807 abuts against the movable baffle 802. Furthermore, the two torsion springs 807 are symmetrically arranged. Example

[0038] A push-pull tile-blocking mechanism for a mahjong machine includes the aforementioned movable baffle mounting structure for a mahjong machine, and a tile-blocking frame 8 for preventing mahjong tiles on a tile-supporting plate of a push-pull tile-feeding device from moving inward. The tile-blocking frame 8 is located inside the tile-supporting plate. It also includes a first tile-blocking frame 801 and a second tile-blocking frame 803, both fixed to the bottom of a tabletop 10. The second tile-blocking frame 803 and the first tile-blocking frame 801 cooperate to form a channel for the push-pull head of the tile-pushing device to slide through. A movable baffle 802 is disposed between the second tile-blocking frame 803 and the first tile-blocking frame 801, with the first tile-blocking frame 801 located between the movable baffle 802 and the tile-blocking frame 8. The movable baffle, the first tile-blocking frame, and the second tile-blocking frame are fitted with a clearance. This arrangement allows the first tile-blocking frame, the second tile-blocking frame, and the tile-blocking frame to be separately configured, thus facilitating the assembly of the mahjong machine. In other embodiments, the first tile-blocking frame and the tile-blocking frame are integrally formed.

[0039] In this embodiment, as Figure 6 and Figure 7 As shown, the second tile holder 803 is located outside the movable baffle 802. A slidable baffle plate 804 is installed on the second tile holder 803. One end of the baffle plate 804 can extend from the first tile holder and abut against the movable baffle 802. This arrangement allows for the matching of mahjong tiles of different sizes via the baffle plate 804 and the movable baffle 802. Furthermore, the second tile holder 803 is provided with a sliding groove 8031, and the baffle plate 804 is provided with an oblong hole. A locking member is threadedly connected to the second tile holder 803. One end of the locking member extends into the oblong hole and abuts against the inner wall of the oblong hole 8041.

[0040] When the card-pushing device pushes the cards, the pushing head can move horizontally through the channel and push the movable baffle 802 to swing and retreat; when the card-push device pushes the cards, the pushing head exits the channel, and the movable baffle 802 is reset under the action of the torsion spring 807. At this time, the movable baffle 802, the card-blocking frame 8, the second card-blocking frame 803 and the first card-blocking frame 801 are flush. The movable baffle 802, the card-blocking frame 8, the second card-blocking frame 803 and the first card-blocking frame 801 block the mahjong tiles on the card-supporting plate from the inside of the card-supporting plate to move inward, realizing the card-push blocking function, thereby ensuring that the mahjong tile wall of the card-push-up is neat and uniform.

[0041] The tabletop 10 has four second card outlets 11. The card blocking frame 8 is located inside the four second card outlets. The card support plate can lift the arranged mahjong tiles from bottom to top and pass them through the second card outlets to send the mahjong tiles to the top of the tabletop 10. Example

Four sets of card picking and transporting systems are arranged around the shuffling tray. The card picking and transporting system includes a card feeding device for picking up mahjong tiles one by one from the shuffling tray and sending them out, a card pushing device for sending multiple stacks of mahjong tiles at once onto the mahjong machine table, and a card pushing device for pushing the mahjong tiles sent out by the card feeding device into the card pushing device.

[0043] The card-feeding device includes a card-feeding housing, within which is a card-feeding channel for transferring mahjong tiles. A conveyor belt driven by a card-feeding motor is installed within the card-feeding channel. A card-suction wheel is located at the card-feeding channel's inlet, and a card-pushing device is located outside the first card-exit of the card-feeding channel. Adjacent card-feeding devices are connected by connecting walls. The four card-feeding devices in the four-set card-picking and transport system are connected end-to-end by four connecting walls to form a shuffling frame (shuffling tank, containing the shuffling space). This shuffling frame surrounds the large shuffling tray. The card-feeding inlets of the card-feeding devices are located on the inner wall of this shuffling frame, and the first card-exit of the card-feeding devices is located on the outer wall of this shuffling frame. Four card-feeding motors are mounted on the outer wall of the shuffling frame.

[0045] A typical tile-pushing device includes a tile-pushing housing, a tile-pushing motor mounted on the housing, a tile-pushing transmission mechanism (existing technology) inside the housing, a tile-bearing block and a tile-pushing head outside the housing. The tile-pushing motor drives the tile-bearing block to move up and down through the transmission mechanism to stack the mahjong tiles, and the tile-pushing motor drives the tile-pushing head to move horizontally through the transmission mechanism to push the stacked mahjong tiles off the tile-bearing block.

[0046] The flat-push tile-loading device includes a tile-receiving plate for receiving and arranging multiple stacks of mahjong tiles, a tile-supporting plate for delivering multiple stacks of mahjong tiles onto the table at once, and a tile-pushing plate for pushing the multiple stacks of mahjong tiles on the tile-receiving plate onto the tile-supporting plate. The tile-receiving plate is set on the tile-loading housing, the tile-supporting plate is located inside the tile-receiving plate, and the tile-pushing plate is located outside the tile-receiving plate and pushes the tiles from the outside to the inside. A tile-storage channel for storing and arranging multiple stacks of mahjong tiles is formed on the tile-receiving plate. One end of the tile-receiving plate extending along the length direction is the tile inlet of the tile-storage channel. A tile-receiving block of the tile-pushing device is set outside the tile inlet. The other end of the tile-receiving plate extending along the length direction is provided with a side baffle. The front and rear obstructions of the tile-storage channel are a front baffle and a tile-pushing plate, respectively. The front baffle is fixedly connected to the tile-supporting plate or integrally formed. The card-feeding housing is equipped with a card-feeding transmission mechanism. A horizontal card-feeding motor drives the card-pushing plate to move horizontally and the card-supporting plate to rise and fall through the card-feeding transmission mechanism. The mahjong machine tabletop 10 has four card-feeding openings. Four card-supporting plates in the four sets of card-picking and transporting systems cooperate with the four card-feeding openings respectively. When the card-supporting plates are raised, they fill the card-feeding openings and become flush with the mahjong machine tabletop 10. The card-feeding transmission mechanism includes a card-supporting plate transmission mechanism for driving the card-supporting plate to rise and fall and a card-pushing plate transmission mechanism for driving the card-pushing plate to move horizontally (existing technology). For the specific structure of the horizontal card-feeding device, please refer to patent documents with publication numbers CN109381855, CN109794059, and CN112023390.

[0047] To prevent mahjong tiles from being pushed out of the support plate and falling into the shuffling tray or getting stuck during the flat-push process, a blocking frame 8 is preferably provided on the inner side of the square support plate. The blocking frame 8 has a blocking part near the inner edge of the support plate, which prevents the mahjong tiles on the support plate from moving further inward.
