Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machines, and particularly relates to an eight-mouth mahjong machine and a card-raising mode switching component thereof. Background Art

[0002] Based on the number of slots for raising the tiles, current fully automatic mahjong machines can be divided into four-slot mahjong machines and double-slot mahjong machines. As the name suggests, a four-slot mahjong machine has only one slot for raising the tiles on each side, while a double-slot mahjong machine has two slots for raising the tiles on each side.

[0003] In a four-slot mahjong machine, after the tiles are raised to the table, the player must pick up a number of tiles in sequence. In a double-slot machine, however, the tiles that are placed on the table from the slot closest to the player are the deal tiles, while the tiles that are placed on the table from the slot closest to the center of the machine are the draw tiles. This allows players to start the game directly without having to manually pick up tiles; they can simply pick up the deal tiles.

[0004] Although the eight-mouth mahjong machine's card-free feature is more popular, the four-mouth mahjong machine also has a large audience, but the current eight-mouth mahjong machine is not compatible with the four-mouth mahjong machine gameplay. Utility Model Content

[0005] The purpose of the invention of the utility model is to provide an eight-mouth mahjong machine and a card-raising mode switching component thereof. The eight-mouth mahjong machine is compatible with the playing method of a four-mouth mahjong machine, and the card-raising mode switching component can be used to switch the card-raising modes corresponding to the two playing methods.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution of the utility model is as follows:

[0007] A card-raising mode switching component for an eight-mouth mahjong machine, the card-raising mode switching component comprising:

[0008] A swing arm having a hinge point movably connected to the mahjong machine;

[0009] A driving unit is used to drive the swing arm to swing around the hinge point so that the swing arm blocks the first card raising board from descending or removes the blockage to the first card raising board, and the first card raising board is used to deliver the card dealing sequence to the table in the eight-slot machine mode.

[0010] The present invention utilizes the principle that a swing arm can change its position by swinging, and utilizes the swing arm in different positions to achieve the purpose of hindering the first card raising board from descending or removing the obstruction to the first card raising board. When the swing arm is in a position where it can hinder the descending of the first card raising board, the first card raising board cannot descend, and only the second card raising board can descend to receive the cards (each side of the eight-mouth mahjong machine is provided with a first card raising board and a second card raising board). At this time, the card raising mode of the mahjong machine is a four-mouth card raising mode; and when the swing arm changes its position to remove the obstruction to the first card raising board, the first card raising board can also descend to receive the cards. At this time, the card raising mode of the mahjong machine is an eight-mouth card raising mode. In this way, users can select the corresponding card raising mode according to their own preferences, and the mahjong machine has a wider audience.

[0011] In the brand-raising mode switching assembly of the present invention, the hinge point is at the end of the swing arm, and the drive unit is a circumferential drive structure provided at the hinge point;

[0012] Alternatively, the swing arm includes a hinge point and a long arm end and a short arm end on both sides of the hinge point, and the drive unit is a circumferential drive structure arranged at the hinge point, or the drive unit is a linear drive structure arranged at the short arm end.

[0013] In order to enable the drive unit to drive the swing arm to produce a larger swing amplitude with a smaller force, the utility model sets the drive unit to be either connected to the hinge point or to the short arm end; the required circumferential drive structure or linear drive structure can be selected at will by those skilled in the art, and the utility model has no special requirements.

[0014] However, in order to facilitate those skilled in the art to understand the present invention, the present invention provides an example, that is, the driving unit includes a lever slidably connected to the mahjong machine, one end of the lever is movably connected to the short arm end, and the other end of the lever is provided with a sensing module, which is used to sense whether the card storage channel of the mahjong machine contains the card dealing sequence sent to the first card raising board.

[0015] When the sensing module senses that a card dealing sequence is stored in the card storage channel, the lever will slide, thereby driving the swing arm to swing to a state where it contacts and blocks the first card raising plate; otherwise, the swing arm will remain in a state where it blocks the first card raising plate from descending.

[0016] At this point, the perception module also has multiple options:

[0017] First, a first elastic structure is provided at the hinge point or the connection between the lever and the swing arm, which causes the swing arm to have a tendency to move toward the bottom of the first card-raising plate. The sensing module is a probe extending into the card storage channel. In the eight-mouth machine working position, the probe is squeezed by the card-dealing sequence, causing the lever to apply a reaction force to the swing arm to offset the movement tendency.

[0018] Secondly, the sensing module includes an infrared detector or a magnetic sensor, and the shift rod is connected to the linear drive. The infrared detector or magnetic sensor and the linear drive are both connected to a control element, which is used to control the operation of the linear drive according to the output signal of the infrared detector or magnetic sensor.

[0019] Obviously, the first form of perception module does not require additional power and is more preferred.

[0020] Preferably, in the above-mentioned card-raising mode switching component, an arcuate surface is formed at one end of the probe facing the card storage channel to facilitate the card dealing sequence to pass over, and the width of the arcuate surface is not less than the width of a mahjong tile.

[0021] The curved surface not only does not hinder the progress of the dealing sequence, but its larger span enables it to contact more mahjong tiles, so that the lever receives the squeezing force from multiple mahjong tiles, making it easier to overcome the inherent movement tendency of the swing arm.

[0022] In the aforementioned card-raising mode switching assembly, the swing arm contacts the first card-raising plate directly or via a push rod mounted on the swing arm. When the swing arm is close to the first card-raising plate, the swing arm can support the first card-raising plate from below. When there is a significant height difference between the swing arm and the first card-raising plate, a push rod is mounted on the swing arm to support the first card-raising plate.

[0023] Preferably, in the above-mentioned card-raising mode switching assembly, the first card-raising board is hinged to the mahjong machine through its fixed end, and in a state of preventing the first card-raising board from descending, the swing arm or top rod is at the bottom of the free end of the first card-raising board.

[0024] Setting the swing arm or push rod at the free end of the first card raising board can, on the one hand, support the first card raising board with a relatively small force to prevent it from falling; on the other hand, it can provide a new lifting point for the first card raising board in a horizontal state, ensuring that the free end of the first card raising board will not collapse when subjected to force (from the table top).

[0025] In a mahjong machine with a 360° rotating push rod, the push rod will return to the starting point from the bottom of the lifting board after pushing the mahjong tile onto the lifting board, and the top rod under the first lifting board is on the running path of the push rod.

[0026] In order to prevent the push rod from interfering with the return of the card-raising push rod to the starting point, in the above-mentioned card-raising mode switching assembly, the push rod is hingedly connected to the swing arm. The push rod has a supporting position in which it stands upright on the swing arm and supports the first card-raising plate, and a avoiding position in which it rotates relative to the swing arm to avoid the mahjong machine actuator passing under the first card-raising plate.

[0027] A second elastic structure is provided between the push rod and the swing arm, which enables the push rod to move toward the supporting position;

[0028] The push rod is formed with a wedge surface for the execution element of the mahjong machine to pass through.

[0029] When the card-loading push rod runs to the position of the push rod, pressure will be applied to the push rod from the wedge surface, causing the push rod to move from the supporting position to the avoidance position. After the card-loading push rod passes, the push rod will automatically return to the supporting position under the action of the second elastic structure.

[0030] The utility model also provides an eight-mouth mahjong machine, which includes a frame, each side of which is movably mounted with a first card raising plate and a second card raising plate, the first card raising plate being close to the edge of the mahjong machine, and the second card raising plate being close to the center of the mahjong machine; the card raising mode switching component is used to change the card raising mode of the first card raising plate;

[0031] When the swing arm is in a state of removing the obstruction to the first card-lifting plate, the first card-lifting plate will rise and fall synchronously with the second card-lifting plate due to the linkage relationship formed between them; and when the swing arm is in a state of blocking the descent of the first card-lifting plate, as the second card-lifting plate descends, no linkage relationship will be formed between the first card-lifting plate and the second card-lifting plate, or the linkage relationship will be disconnected by the swing arm; in this way, the card-lifting mode of the first card-lifting plate can be controlled.

[0032] Compared with the prior art, the technical effects of the present invention are embodied in:

[0033] (1) The present invention utilizes the principle that the swing arm can change its position by swinging, and utilizes the swing arm in different positions to achieve the purpose of hindering the first card raising board from descending or removing the obstruction to the first card raising board. When the swing arm is in a position where it can hinder the first card raising board from descending, the first card raising board cannot descend, and only the second card raising board can descend to receive the cards (each side of the eight-mouth mahjong machine is provided with a first card raising board and a second card raising board). At this time, the card raising mode of the mahjong machine is a four-mouth card raising mode; and when the swing arm changes its position to remove the obstruction to the first card raising board, the first card raising board can also descend to receive the cards. At this time, the card raising mode of the mahjong machine is an eight-mouth card raising mode. In this way, users can choose the corresponding card raising mode according to their own preferences, and the mahjong machine has a wider audience.

[0034] (2) The utility model sets a probe on the lever that extends into the card storage channel to sense whether the card dealing sequence is stored in the card storage channel, thereby realizing the regulation of the card raising mode of the first card raising plate. Not only is the regulation accuracy high, but also no additional power is required.

[0035] (3) The utility model supports the first card-raising board by means of a push rod erected at the end of the swing arm, and the utility model also sets the swing push rod to be at the free end of the first card-raising board. On the one hand, it can support the first card-raising board with a relatively small force to prevent it from falling; on the other hand, it can provide a new lifting point for the first card-raising board in a horizontal state, ensuring that the free end of the first card-raising board will not collapse when subjected to force (from the table top).

[0036] (4) In the present invention, the push rod is movably connected to the swing arm, so that the existence of the push rod will not affect the 360° movement of the push rod in the mahjong machine to return to the starting point. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] like Figure 1 and Figure 2 Shown, combined Figure 3 It can be seen that the card-raising mode switching component of the eight-mouth mahjong machine in this embodiment includes a swing arm 1, which includes a hinge point 11 movably connected to the base 2 or other components of the mahjong machine (such as the frame 100, the card storage device, etc., which are not limited in this embodiment) and a long arm end 12 and a short arm end 13 on both sides of the hinge point 11. The short arm end 13 is connected to the drive unit (the drive unit is a linear drive structure) to drive the swing arm 1 to swing; at this time, the drive unit (at this time, the drive unit is a circumferential drive structure) can also be connected to the hinge point 11. Obviously, the hinge point 11 can also be directly set at the end of the swing arm 1. At this time, it is better for the drive unit (also a circumferential drive structure) to be connected to the hinge point 11.

[0045] When the driving unit is working, the swing arm 1 will swing, thereby changing the position of the long arm end 12. When the long arm end 12 swings to the bottom of the first card-raising board 200, it can hinder the first card-raising board 200 from descending. When the long arm end 12 swings to the side of the first card-raising board 200, it removes the obstruction to the first card-raising board 200. In this way, the card-raising mode of the first card-raising board 200 can be changed.

[0046] This embodiment is described by taking the short arm end 13 connected to the drive unit as an example. Figure 1 As shown, the driving unit includes a lever 3, which is slidably mounted on the base 2. Two X-shaped lock buckles 4 are detachably mounted on the base 2. The lever 3 is restricted to the base 2 by the X-shaped lock buckles 4; one end of the lever 3 is movably connected to the short arm end 13, and the other end is provided with a probe 5.

[0047] The probe 5 extends into the card storage channel 500 of the mahjong machine. When a card dealing sequence with a height equivalent to that of the probe 5 is stored in the card storage channel 500, the card dealing sequence will squeeze the probe 5, thereby driving the lever 3 to slide, and then driving the swing arm 1 to swing, so that the swing arm 1 and the top rod 6 move to the side and lower part of the first card raising plate 200, and the first card raising plate 200 can drop freely.

[0048] Obviously, when there is no card dealing sequence at the same height as the probe 5 in the card storage channel 500, there are two situations: no cards have been deposited, or cards have been deposited but have been sent to the first card raising plate 200, and the probe 5 cannot sense the pressure from the card dealing sequence; at this time, in order to enable the swing arm 1 to automatically return to the center, it is necessary to set a first elastic structure (such as a torsion spring) at the connection position between the lever 3 and the swing arm 1 or at the hinge point 11 of the swing arm 1, so that the swing arm 1 has a tendency to move toward the bottom of the first card raising plate 200.

[0049] It can be seen that in this embodiment, the probe 5 is formed with a curved surface 51 at one end facing the card storage channel 500 to facilitate the card dealing sequence to pass over, and the width of the curved surface 51 is greater than the width of the lever 3, and even greater than the width of a mahjong tile; on the one hand, it prevents the lever 3 from being out of the limit, and on the other hand, the curved surface 51 not only does not hinder the progress of the card dealing sequence, but its larger span also enables it to contact more mahjong tiles, so that the lever 3 receives the squeezing force from multiple mahjong tiles, making it easier to overcome the inherent movement tendency of the swing arm 1.

[0050] In this embodiment, when the height difference between the swing arm 1 and the first card-raising plate 200 is small, the long arm end 12 can directly contact the first card-raising plate 200; and when the height difference between the swing arm 1 and the first card-raising plate 200 is large, such as Figure 1 and Figure 2 As shown, a push rod 6 can be erected at the long arm end 12 to support the first lifting plate 200.

[0051] As is known to all, in a mahjong machine in which the card-loading push rod 600 is rotatable 360°, the card-loading push rod 600 will return to the starting point from the bottom of the card-lifting plate after pushing the mahjong tiles onto the card-lifting plate, and the top rod 6 under the first card-lifting plate 200 is on the running path of the card-loading push rod 600.

[0052] In order to prevent the push rod 6 from interfering with the card-lifting push rod 600 returning to the starting point, the push rod 6 is arranged to be hinged to the swing arm 1 (such as using a hinge) in this embodiment. The push rod 6 has a supporting position that is upright on the swing arm 1 and supports the first card-lifting plate 200, and a avoiding position that rotates relative to the swing arm 1 to avoid the card-lifting push rod 600; and a second elastic structure (such as a torsion spring) is provided between the push rod 6 and the swing arm 1 to enable the push rod 6 to have a tendency to move toward the supporting position.

[0053] When the card-loading push rod 600 moves to the position of the push rod 6, it will apply pressure to the push rod 6 from the wedge surface, causing the push rod 6 to move from the supporting position to the avoiding position. After the card-loading push rod 600 passes, the push rod 6 will automatically return to the supporting position under the action of the second elastic structure. Obviously, when the card-loading push rod 600 returns to the starting point along the original path after completing the card-loading action, the push rod 6 can be fixed to the swing arm 1.

[0054] When the card-loading push rod 600 moves to the position of the push rod, it will apply pressure to the push rod 6 from the wedge surface 61, causing the push rod 6 to move from the supporting position to the avoiding position. After the card-loading push rod 600 passes, the push rod 6 will automatically return to the supporting position under the action of the second elastic structure. Obviously, when the card-loading push rod 600 returns to the starting point along the original path after completing the card-loading action, the push rod 6 can be fixed to the swing arm 1.

[0055] It is foreseeable that after the card dealing sequence is sent to the first card raising board 200, the swing arm 1 and the push rod 6 will remain below the first card raising board 200, that is, the normal state of the swing arm 1 and the push rod 6 is to support the first card raising board 200 and prevent the first card raising board 200 from descending. Therefore, in this embodiment, the force application position of the push rod 6 or the swing arm 1 is set to the free end of the first card raising board 200. On the one hand, it is conducive to supporting the first card raising board 200 with minimal force, and on the other hand, it can provide a new lifting point for the first card raising board 200 in a horizontal state, ensuring that the free end of the first card raising board 200 will not collapse when subjected to force (from the table).

[0056] Example 2

[0057] like Figure 3 As shown, this embodiment is an eight-mouth mahjong machine, which includes a frame 100. Each side of the frame 100 is movably mounted with a first card raising plate 200 and a second card raising plate 300. The first card raising plate 200 is close to the edge of the mahjong machine, and the second card raising plate 300 is close to the center of the mahjong machine.

[0058] In this embodiment, only one card-raising drive assembly 400 is provided to drive all the first card-raising plates 200 and the second card-raising plates 300 in the mahjong machine. The card-raising drive assembly 400 directly drives each second card-raising plate 300, and the first card-raising plates 200 of each party are linked to the corresponding second card-raising plates 300 through the linkage assembly 7;

[0059] The solution of using a card-raising drive assembly 400 to simultaneously drive the second card-raising plates 300 located on the four sides of the mahjong machine has been previously described in the patent documents of the patentee and will not be described in detail in this embodiment. The focus will be on the linkage assembly 7.

[0060] like Figure 4 and Figure 5 As shown, the linkage assembly 7 includes a magnetic member 71 disposed at the bottom of the first card-lifting plate 200 and a metal member 72 disposed at the bottom of the second card-lifting plate 300. The metal member 72 is attracted by the magnetic member 71, causing the first card-lifting plate 200 and the second card-lifting plate 300 to be connected, forming a linkage relationship. Obviously, swapping the metal member 72 and the magnetic member 71, or replacing the metal member 72 with another magnetic member 71, can achieve the same effect.

[0061] Obviously, the linkage relationship generated by the linkage component 7 between the first card raising plate 200 and the second card raising plate 300 is not very strong. When the second card raising plate 300 descends and the first card raising plate 200 is prevented from descending, the linkage relationship between the two is disconnected.

[0062] The working principle of the eight-mouth mahjong machine in this embodiment is as follows:

[0063] When the card-delivering sequence at the same height as that at which the probe 5 is located is stored in the card-delivering passage 500, the push rod 6 remains in its normal position, and the first card-delivering plate 200 cannot be lowered, and only the second card-delivering plate 300 can be lowered to receive the cards. At this time, the card-delivering mode of the mahjong machine is the four-mouth card-delivering mode. When the card-delivering sequence at the same height as that at which the probe 5 is located is stored in the card-delivering passage 500, the card-delivering sequence will squeeze the probe 5, causing the lever 3 to slide, thereby causing the swing arm 1 to swing, causing the push rod 6 to move to the side and lower part of the first card-delivering plate 200, thereby removing the obstruction to the first card-delivering plate 200. At this time, the first card-delivering plate 200, connected to the linkage assembly 7, descends together with the second card-delivering plate 300 to receive the cards. At this time, the card-delivering mode of the mahjong machine is the eight-mouth card-delivering mode.
