Description

Technical Field

[0001] The present invention belongs to the technical field of mahjong machines, and particularly relates to an eight - port mahjong machine for upright mahjong tiles. Background Art

[0002] In the current mahjong machine market, for an eight - port mahjong machine, after the mahjong machine automatically shuffles the cards, both the single - layer thirteen starting mahjong tiles and the double - layer mahjong tiles are arranged. One needs to first push the cards and then turn the cards by hand to stand them all upright before being able to play mahjong for entertainment.

[0003] This will cause it to be very difficult for beginners to immediately stand up the starting mahjong tiles when the number of starting tiles is relatively large.

[0004] Therefore, it is necessary to design an eight - port mahjong machine for upright mahjong tiles so that when the starting mahjong tiles rise to the tabletop, they are already upright, avoiding the actions of pushing and turning the cards by hand before playing mahjong for entertainment. Since the starting mahjong tiles are already standing upright, one can immediately play mahjong for entertainment. Summary of the Invention

[0005] The purpose of the present invention is to provide an eight - port mahjong machine for upright mahjong tiles so that when the starting mahjong tiles rise to the tabletop, they are already upright, avoiding the action of turning the cards.

[0006] To achieve the above purpose, the present invention provides an eight - port mahjong machine for upright mahjong tiles, including a frame. The frame is provided with a bifurcated card track, a pushing rod, and a first wire transmission system and a second wire transmission system for driving the pushing rod to move along the length direction of the bifurcated card track. The bifurcated card track includes a main card track and an outer card track and an inner card track that bifurcate and extend from the outlet end of the main card track. The outer card track includes a straight upright track and a 90 - degree twisting track provided between the upright track and the main card track. In the cross - section perpendicular to the extending direction of the card track, starting from its starting point, the bottom wall of the 90 - degree twisting track gradually changes from horizontal to inclined and finally gradually changes to vertical, and one of its side walls gradually changes from vertical to inclined and finally gradually changes to horizontal, so that the mahjong tiles are twisted by 90 degrees and then enter the upright track.

[0007] The outlet end of the main card track is an automatic card - splitting port. The depth of the outer card track at the bifurcation position is greater than the depth of the inner card track at the bifurcation position, and automatic card splitting during the pushing process is achieved through the depth difference at the bifurcation position. The starting point of the 90 - degree twisting track is the automatic card - splitting port.

[0008] The upright track is used to accommodate 13 upright mahjong tiles. In each cross - section perpendicular to the extending direction of the card track, the bottom wall is horizontally arranged and the side walls are vertically arranged.

[0009] The first wire transmission system and the second wire transmission system are arranged directly above or directly below the bifurcated lane; the first wire transmission system is used to drive the single-layer card pushing rod to move along the entire length of the outer lane, and the second wire transmission system is used to drive the multi-layer card pushing rod to move along the entire length of the total lane and the inner lane.

[0010] Both the first wire transmission system and the second wire transmission system include a driving wheel, a driven wheel, a steel wire rope wound around both of them at the same time, an elastic pushing slider fixed to both ends of the steel wire rope, and a pushing rod arranged on the pushing slider. The steel wire rope of the first wire transmission system has a first pushing section wound and fixed to extend along the entire length of the outer lane, and the steel wire rope of the second wire transmission system has a second pushing section wound and fixed to extend along the entire length of the total lane and the inner lane. Each point on the first pushing section and the second pushing section is in the same vertical plane as the midline in the width direction of its corresponding lane, so that the pushing rods of the first wire transmission system and the second wire transmission system are kept in the center of their corresponding lanes when pushing cards.

[0011] Both the first wire transmission system and the second wire transmission system are arranged directly below the bifurcated lane; through holes extending along the length direction of the bifurcated lane are respectively formed at the midline positions in the width direction of the overall structures of the total lane, the outer lane and the inner lane, namely a total lane pushing rod groove, an outer lane pushing rod groove and an inner lane pushing rod groove, and the first pushing section and the second pushing section are attached to directly below their corresponding pushing rod grooves, so that the pushing rod can pass through the pushing rod groove and extend upward; or, both the first wire transmission system and the second wire transmission system are arranged directly above the bifurcated lane and fixedly installed at the bottom of a tabletop, and the first pushing section and the second pushing section are arranged below the tabletop, so that the single-layer card pushing rod and the multi-layer card pushing rod can be aligned downward with the midline positions in the width direction of their corresponding lane structures when pushing cards.

[0012] The driving wheel of the first wire transmission system is located at the bifurcation position of the bifurcated lane, the driving wheel of the second wire transmission system is located at the entrance end of the bifurcated lane, and the driven wheels of the first wire transmission system and the second wire transmission system are respectively located at the two exit ends of the bifurcated lane; the pushing sliders of the first wire transmission system and the second wire transmission system are arranged to be bendable at their driving wheels to rotate upward and downward, so as to drive the pushing rod to turn upward and downward at the driving wheel.

[0013] The first wire transmission system and the second wire transmission system further include a first drive motor and a second drive motor. The output shafts of the first drive motor and the second drive motor are respectively in transmission connection with the driving wheels of the first wire transmission system and the second wire transmission system; or, the first wire transmission system and the second wire transmission system further include a shared drive motor. The output shaft of the drive motor is in transmission connection with one of the first driving wheel and the second driving wheel, and the first driving wheel and the second driving wheel are in transmission connection through a third steel wire rope.

[0014] The card-pushing slider is an elastic plastic square slider, and the elastic plastic square slider is accommodated in a slider groove. When the first wire transmission system and the second wire transmission system are arranged directly below the bifurcated card track, the slider groove is arranged at the bottom of the frame. When the first wire transmission system and the second wire transmission system are both arranged directly above the bifurcated card track, the slider groove is arranged at the bottom of the table board, and the shape of the slider groove matches the curvature, slope, and angle of the bifurcated card track.

[0015] The material of the steel wire rope is a plastic-coated steel wire rope.

[0016] The eight-opening mahjong machine for upright mahjong tiles of the present invention is provided with a 90-degree twisting track on the outer card track. From its starting point, the bottom wall of the 90-degree twisting track gradually changes from horizontal to inclined and finally gradually changes to vertical, and one side side wall gradually changes from vertical to inclined and finally gradually changes to horizontal, so that the mahjong tiles are twisted by 90 degrees and then enter the upright track. Thus, when the starting mahjong tiles rise to the table top, they have already been upright, avoiding the need to push the cards by hand and turn the cards by hand before playing mahjong. Since the starting mahjong tiles have already been set up, the mahjong can be played immediately. The present invention enables the eight-opening mahjong machine to stand upright thirteen mahjong tiles, which is a first in the domestic and foreign mahjong machine markets.

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0024] First embodiment: Double - track card - pushing device of an eight - hole mahjong machine driven by a card - pushing rod at the bottom

[0025] Figure 1 It is a structural schematic diagram of the eight - hole mahjong machine for upright mahjong tiles of the present invention, showing the position of the 90 - degree twisting track 122. Among them, the starting point of the 90 - degree twisting track 122 corresponds to the flat - laying position of the mahjong tiles, and the end point 124 of the 90 - degree twisting track 122 corresponds to the upright position of the mahjong tiles. However, due to the complexity of the structure of the 90 - degree twisting track 122 itself, the three - dimensional structure of the 90 - degree twisting track 122 is not shown in detail in the figure. Instead, part of the structure of the 90 - degree twisting track 122 is cut out and represented by ellipsis, and only its position is shown by a red wavy line.

[0026] Figure 2 Schematic diagram of the twisting method of the bottom wall of the 90 - degree twisting track 122. Figure 3 As Figure 1 Front view of an eight - hole mahjong machine for upright mahjong tiles at its main card track, showing the card - pushing method with the card - pushing rod in the center of the card track.

[0027] As Figures 1 - 3 Shown, the eight - hole mahjong machine for upright mahjong tiles of the present invention includes a frame 1. The frame 1 is provided with a bifurcated card track. The bifurcated card track has a common straight main card track 11, and an arc - shaped outer card track 12 and an inner card track 13 that bifurcate and extend from the outlet end of the main card track 11. The main card track 11 is used for three layers of mahjong tiles to slide through, and the outer card track 12 and the inner card track 13 are used for a single layer of mahjong tiles and two layers of mahjong tiles to slide through respectively. Therefore, the inlet end of the main card track 11 is the inlet end of the bifurcated card track, and the outlet ends of the outer card track 12 and the inner card track 13 are the two outlet ends of the bifurcated card track.

[0028] The outer track 12 is located outside the inner track 13. That is to say, both the outer track 12 and the inner track 13 include at least one arc segment, and the arc radius of the outer track 12 is greater than that of the inner track 13.

[0029] In the present invention, the overall total track 11 and the inner track 13 do not undergo any rollover or torsion. That is to say, in each cross-section perpendicular to the extending direction of the track, the bottom wall is horizontally arranged and the side wall is vertically arranged for both the total track 11 and the inner track 13.

[0030] The outer track 12 includes a straight upright track 123 and a 90-degree torsion track 122 provided between the upright track 123 and the total track 11. The upright track 123 is used to accommodate 13 upright starting mahjong tiles. In each cross-section perpendicular to the extending direction of the track, the bottom wall of the upright track 123 is horizontally arranged and the side wall is vertically arranged.

[0031] A schematic diagram of the torsion mode of the bottom wall of the 90-degree torsion track 122 is as Figure 2 shown. As Figure 2 shown, in the cross-section perpendicular to the extending direction of the track, starting from its starting point, the bottom wall of the 90-degree torsion track 122 gradually changes from horizontal to inclined and finally gradually changes to vertical (i.e., becomes the side wall), and one of its side walls gradually changes from vertical to inclined and finally gradually changes to horizontal (i.e., becomes the bottom wall), so that the mahjong tiles are torsionally rotated by 90 degrees and then enter the upright track. The other side wall gradually shortens and finally disappears. Therefore, an arc-shaped slope is formed at the gradual change position of the bottom wall and the side wall in the 90-degree torsion track 122.

[0032] The exit end of the total track 11 is a bifurcation position (i.e., the automatic tile-sorting port 14). The depth of the outer track 12 at the bifurcation position is greater than the depth of the inner track 13 at the bifurcation position. Automatic tile sorting during the tile-pushing process is achieved through the depth difference at the bifurcation position, that is, the mahjong tiles with small depth and small depth are sorted onto different tracks; among them, the upper two layers of the three layers of mahjong tiles automatically enter the inner track 13, and the lower layer of mahjong tiles automatically enters the outer track 12, thus entering the 90-degree torsion track 122, so that the mahjong tiles are flipped by 90 degrees and enter the upright track 123 in an upright manner. In this embodiment, the starting point of the 90-degree torsion track 122 is the automatic tile-sorting port 14. In other embodiments, the starting point of the 90-degree torsion track 122 can be located downstream of the automatic tile-sorting port 14.

[0033] Therefore, in order to make the heights of the outer tile lane 12 and the inner tile lane 13 equal at their respective exit ends, the part of the outer tile lane 12 downstream of the bifurcation position is an upward slope with a gradually decreasing depth. Both the outer tile lane 12 and the inner tile lane 13 finally extend upward to the tabletop. Thus, the mahjong tiles can slide along the bifurcated tile lanes to achieve tile pushing and tile splitting. The inner tile lane 13 is a double-layer tile lane for two layers of mahjong tiles to slide; the outer tile lane 12 is a single-layer tile lane for one layer of mahjong tiles to slide.

[0034] Each tile lane of the bifurcated tile lane (i.e., the total tile lane 11, the outer tile lane 12, and the inner tile lane 13) is composed of a bottom wall 101 and side walls 102.

[0035] As Figure 3 shown, for the total tile lane 11 and the inner tile lane 13, through holes (i.e., penetrating the bottom wall 101) are respectively provided at the midline positions in the width direction of their overall structures (i.e., the midline positions in the width direction of the bottom wall 101), and the total tile lane pusher slots 111 and the inner tile lane pusher slots 131 extending along the length direction of the bifurcated tile lane are provided.

[0036] For the 90-degree turning track 122 and the upright track 123 of the outer tile lane 12, through holes are respectively provided at the midline positions in the width direction of their overall structures (i.e., the bottom midline position in the overall width direction of the 90-degree turning track 122 and the midline position in the width direction of the bottom wall 101 of the upright track 123), and the outer tile lane pusher slots 121 extending along the length direction of the bifurcated tile lane are provided.

[0037] The total tile lane pusher slot 111 bifurcates at the bifurcation position to communicate with the outer tile lane pusher slot 121 and the inner tile lane pusher slot 131 simultaneously. Thus, the total tile lane pusher slot 111 and the outer tile lane pusher slot 121 together form the tile pushing slot for single-layer mahjong, the total tile lane pusher slot 111 and the inner tile lane pusher slot 131 together form the tile pushing slot for double-layer mahjong, and the overlapping part between the two tile pushing slots, the first tile pushing slot and the second tile pushing slot, is the total tile lane pusher slot 111.

[0038] The double-tile-lane tile pushing device of the eight-tile mahjong machine includes a first wire transmission system and a second wire transmission system for driving the tile pushing rod to move along the length direction of the bifurcated tile lane. Among them, the first wire transmission system and the second wire transmission system are arranged directly above or directly below the bifurcated tile lane. The first wire transmission system is used to drive the single-layer tile pushing slider 104 to move along the entire length of the outer tile lane 12, and further drive the single-layer tile pushing rod 105 to move along the entire length of the outer tile lane 12. The second wire transmission system is used to drive the multi-layer tile pushing slider 204 to move along the entire lengths of the total tile lane 11 and the inner tile lane 13, and further drive the multi-layer tile pushing rod 205 to move along the entire lengths of the total tile lane 11 and the inner tile lane 13.

[0039] In this embodiment, the first steel wire transmission system and the second steel wire transmission system are both disposed directly below the bifurcation card lane. Thus, the steel wire transmission systems are arranged in the bottom space position of the rack 1, which can effectively reduce the twisting friction force, avoid the motor from being stuck due to the twisting friction force of the steel wire rope at the turning of the track, and can avoid basically no interference with the rest of the mahjong machine.

[0040] As Figure 4 and Figure 5 shown, the first steel wire transmission system mainly includes: a first driving wheel 101, a first driven wheel 102, a first steel wire rope 103 wound around both of them at the same time, a single-layer card pushing slider 104 with an elastic structure fixed to both ends of the first steel wire rope 103, and a single-layer card pushing rod 105 disposed on the single-layer card pushing slider 104; similarly, the second steel wire transmission system mainly includes: a second driving wheel 201, a second driven wheel 202, a second steel wire rope 203 wound around both of them at the same time, a multi-layer card pushing slider 204 with an elastic structure fixed to both ends of the second steel wire rope 203, and a multi-layer card pushing rod 205 disposed on the multi-layer card pushing slider 204. That is to say, both the first steel wire transmission system and the second steel wire transmission system include a driving wheel, a driven wheel, a steel wire rope wound around both of them at the same time, a pushing slider fixed to both ends of the steel wire rope, and a pushing rod disposed on the pushing slider.

[0041] Among them, the first steel wire rope 103 of the first steel wire transmission system has a first pushing section wound and fixed to extend along the entire length of the outer card lane 12, and the second steel wire rope 203 of the second steel wire transmission system has a second pushing section wound and fixed to extend along the entire length of the total card lane 11 and the inner card lane 13. Each point on the first pushing section and the second pushing section is in the same vertical plane as the midline in the overall structural width direction of its corresponding card lane, so that the pushing rods of the first steel wire transmission system and the second steel wire transmission system remain in the center of their corresponding card lanes when pushing cards.

[0042] In this embodiment, since the first steel wire transmission system and the second steel wire transmission system are both disposed directly below the bifurcation card lane, therefore, through holes extending along the length direction of the bifurcation card lane are respectively opened at the midline positions in the overall structural width direction of the bottom walls 101 of the total card lane, the outer card lane and the inner card lane, namely, a total card lane pushing rod groove, an outer card lane pushing rod groove and an inner card lane pushing rod groove. The first steel wire rope 103 of the first steel wire transmission system and the second steel wire rope 203 of the second steel wire transmission system are both wound into two layers, and the first pushing section of the first steel wire rope 103 and the second pushing section of the second steel wire rope 203 are both attached directly below their corresponding pushing rod grooves, so that the single-layer card pushing rod 105 and the multi-layer card pushing rod 205 can pass through the pushing rod grooves and extend upward. Therefore, the winding and installation method of the steel wire ropes in the entire transmission system is simple and convenient, and there will be no twisting friction force caused by bending.

[0043] Both the single - deck pushing slider 104 and the multi - deck pushing slider 204 are elastic structures. Thus, the single - deck pushing slider 104 and the multi - deck pushing slider 204 can bend at the first driving wheel 101 and the second driving wheel 201 to rotate upward and downward, so as to drive the single - deck pushing rod 105 and the multi - deck pushing rod 205 to flip upward and downward at the corresponding driving wheels. In this embodiment, since the first wire transmission system and the second wire transmission system are arranged directly below the bifurcated card lane, the slider grooves are arranged at the bottom of the frame. For example, the multi - deck pushing slider 204 is accommodated in its corresponding slider groove 206, and the slider groove 206 is installed at the bottom of the frame.

[0044] The first driving wheel 101 is located at the bifurcation position of the bifurcated card lane, the second driving wheel 201 is located at the entrance end of the bifurcated card lane, and the first driven wheel 102 and the second driven wheel 202 are respectively located at the two exit ends of the bifurcated card lane (i.e., the exit ends of the outer card lane 12 and the inner card lane 13), whereby the single - deck pushing rod 105 and the multi - deck pushing rod 205 can both achieve transmission between the entrance end and the exit end of the bifurcated card lane.

[0045] In this embodiment, the first wire transmission system and the second wire transmission system further include a first driving motor and a second driving motor fixedly installed on the frame 1 through flanges. Both the first driving motor and the second driving motor have output shafts extending in the horizontal direction perpendicular to the total card lane 11, and the output shafts of the first driving motor and the second driving motor are respectively in transmission connection with the first driving wheel 101 and the second driving wheel 201.

[0046] It should be noted that the starting times of the first driving motor and the second driving motor are inconsistent. The first driving motor is set to start rotating forward when the second driving motor drives the pushing rod of the second wire transmission system to reach the bifurcation position of the bifurcated card lane, so as to drive the pushing rod of the first wire transmission system to flip upward at the driving wheel and move along the outer card lane pushing rod groove 121. In addition, the first driving motor and the second driving motor are set to reverse when driving the pushing rods of the first and second wire transmission systems to reach the exit of the bifurcated card lane, so that the pushing rods return below the driving wheels.

[0047] In other embodiments, the first wire transmission system and the second wire transmission system can share the same driving motor.

[0048] The materials of the first steel wire rope 103 and the second steel wire rope 203 are plastic - coated steel wire ropes formed by wrapping a layer of plastic outside stainless steel wires, so they are firm and durable and not easily damaged. Preferably, the first steel wire rope 103 and the second steel wire rope 203 are wound around the driving wheels and the driven wheels for multiple turns to increase the friction force.

[0049] The single-layer card pushing rod 105 is used to push a single mahjong card at the bottom of the three-layer mahjong cards. The multi-layer card pushing rod 205 is used to push all three-layer mahjong cards in the main card track 11 and push the top two-layer mahjong cards in the inner card track 13. The single-layer card pushing rod 105 and the multi-layer card pushing rod 205 are respectively injection-molded into one body with the single-layer card pushing slider 104 and the multi-layer card pushing slider 204 (i.e., the pushing sliders of the first and second wire transmission systems).

[0050] Before the card pushing and card splitting operations, the single-layer card pushing slider 104 and the multi-layer card pushing slider 204 are respectively hidden under the first steel wire rope 103 and the second steel wire rope 203. When the card pushing instruction is obtained, the second drive motor first drives the second driving wheel 201 to rotate, and then drives the second steel wire rope 203 to rotate, so that the multi-layer card pushing rod 205 is transmitted to the second card pushing section of the second steel wire rope 203, and then the card pushing and card splitting actions of the mahjong cards are completed. When the second drive motor drives the multi-layer card pushing rod 205 (i.e., the card pushing rod of the second wire transmission system) to reach the bifurcation position of the bifurcation card track, the card splitting is realized at this time. Another transmission system is needed to push the mahjong cards at the bottom layer. Therefore, the first drive motor starts to drive the first driving wheel 101 to rotate, and then drives the first steel wire rope 103 to rotate, so as to drive the single-layer card pushing rod 105 to turn upwards to the upper layer of the first steel wire rope 103 and move along the outer card track push rod groove. Thus, the card pushing and card splitting actions of the mahjong cards are further completed.

[0051] The single-layer card pushing rod 105 and the multi-layer card pushing rod 205 are set to be able to be transmitted to the outlet end of the bifurcation card track simultaneously through the transmission of the first steel wire rope 103 and the second steel wire rope 203, so that the card pushing actions of the single-layer card pushing rod 105 and the multi-layer card pushing rod 205 are synchronous. In addition, in order to ensure the synchronous rotation of the single-layer card pushing rod 105 and the multi-layer card pushing rod 205, the radius of the first driving wheel 101 needs to be smaller than that of the second driving wheel 201.

[0052] In addition, the first steel wire transmission system and the second steel wire transmission system also include a plurality of guide wheels fixedly installed at the bottom of the frame 1, and the guide wheels are respectively arranged on both sides of the first steel wire rope 103 and the second steel wire rope 203, so that the first steel wire rope 103 and the second steel wire rope 203 are confined between the guide wheels on both sides, ensuring that the overall shapes of the first steel wire rope 103 and the second steel wire rope 203 are both arc-shaped, and the shape of the first steel wire rope 103 on the horizontal plane is as close to the shape of the outer card road as possible, and the shape of the second steel wire rope 203 on the horizontal plane is as close to the shape of the total card road and the inner card road on the horizontal plane as possible, so that the first steel wire rope 103 and the second steel wire rope 203 are respectively transmitted along the curved card road at the bottom of the branched card road of the frame 1 to avoid jamming caused by twisting friction. Preferably, the guide wheels are respectively arranged at the tangent points of the circular arc curve and the straight line of the first steel wire rope 103 and the second steel wire rope 203 and the midpoint of the circular arc curve, so that the shapes of the first steel wire rope 103 and the second steel wire rope 203 on the horizontal plane can fit the shapes of the corresponding card pushing slots on the horizontal plane as closely as possible when a small number of guide wheels are required.

[0053] In this embodiment, the first driven wheel 102, the second driven wheel 202 and the guide wheel are all fixedly mounted on the bottom of the frame 1. The first driven wheel 102, the second driven wheel 202 and the guide wheel are respectively matched with a bearing with a small clearance, and the bearing is fixedly mounted on the bottom of the frame 1 through a pin, so that the first driven wheel 102, the second driven wheel 202 and the guide wheel are fixedly mounted on the frame 1, ensuring that the driven wheel and the guide wheel rotate flexibly, smoothly and without "stuck points" during transmission.

[0054] Since the downstream part of the outer card path 12 at the bifurcation position is an upward slope with a gradually decreasing depth, in order to ensure that the first steel wire rope 103 of the first steel wire transmission system can be transmitted upward along the slope, two clamping wheels are provided at the starting end of the slope of the outer card path 12, for clamping the upper first steel wire rope 103 downward at this position, and the gap between the two clamping wheels must be larger than the width of the single-layer card pushing rod 105 to avoid interference between the single-layer card pushing rod 105 and the two clamping wheels during transmission.

[0055] In this embodiment, the working principle of the eight - port mahjong machine with upright mahjong tiles is as follows: Three layers of mahjong tiles are on the main card track. The driving motor rotates forward to drive the fine steel wire rope, which in turn drives the pushing rod on the card - pushing slider to move along the length direction of the card track until the cards are pushed to the position of the automatic card - distributing port 14. At this time, the upper two layers of mahjong tiles automatically enter the inner card track under the push of the pushing rod and finally move forward and rise to the tabletop; the lower layer of mahjong tiles automatically enters the outer card track and thus enters the 90 - degree turning track of the outer card track. After the mahjong tiles are flipped 90 degrees through the 90 - degree turning track, they enter the upright track 123 in an upright manner. Thus, under the push of the pushing rod, thirteen upright starting mahjong tiles move forward to the tabletop to realize the entertainment of playing cards without manual card - flipping.

[0056] Second Embodiment: Double - track Card - Pushing Device of the Eight - Port Mahjong Machine

[0057] The double - track card - pushing device of the eight - port mahjong machine according to the second embodiment of the present invention has a frame 1 and a structure of the bifurcated card track that is basically the same as that of the double - track card - pushing device of the first embodiment of the present invention as shown Figure 1 The difference is only that the main - track push - rod groove 111, the outer - track push - rod groove 121, and the inner - track push - rod groove 131 can be retained or omitted as the case may be.

[0058] In addition, in this embodiment, both the first steel - wire transmission system and the second steel - wire transmission system are arranged directly above the bifurcated card track and fixedly installed at the bottom of a tabletop. Thus, the steel - wire transmission system is arranged on the top of the frame rather than inside the frame, which can effectively reduce the torsional friction force, avoid the motor from being stuck due to the torsional friction force of the steel wire rope at the track turning, and can avoid basically no interference with the rest of the mahjong machine.

[0059] In this embodiment, the first steel - wire transmission system also includes: a first driving wheel, a first driven wheel, a first steel wire rope wound around both of them at the same time, a single - layer - card card - pushing slider with an elastic structure fixed to both ends of the first steel wire rope, and a single - layer - card pushing rod arranged on the single - layer - card card - pushing slider; similarly, the second steel - wire transmission system mainly includes: a second driving wheel, a second driven wheel, a second steel wire rope wound around both of them at the same time, an elastic multi - layer - card card - pushing slider fixed to both ends of the second steel wire rope, and a multi - layer - card pushing rod arranged on the multi - layer - card card - pushing slider. That is to say, both the first steel - wire transmission system and the second steel - wire transmission system include a driving wheel, a driven wheel, a steel wire rope wound around both of them at the same time, a card - pushing slider fixed to both ends of the steel wire rope, and a pushing rod arranged on the card - pushing slider.

[0060] The first wire rope of the first wire transmission system has a first card-pushing section that is wound and fixed to extend along the entire length of the outer card lane, and the second wire rope of the second wire transmission system has a second card-pushing section that is wound and fixed to extend along the entire length of the total card lane and the inner card lane. Each point on the first card-pushing section and the second card-pushing section is in the same vertical plane as the midline in the width direction of its corresponding card lane, so that the card-pushing rods of the first wire transmission system and the second wire transmission system remain in the center of their corresponding card lanes when pushing the cards.

[0061] The difference from the first embodiment of the present invention is that in this embodiment, since both the first wire transmission system and the second wire transmission system are provided directly above the bifurcated card lane, therefore, it is not necessarily required to open a through card lane groove extending along the length direction of the bifurcated card lane at the midline position in the width direction of the bottom walls of the total card lane, the outer card lane, and the inner card lane, which depends on the situation. In this embodiment, since the height of the inner card lane is higher than that of the outer card lane and the total card lane, only the midline position in the width direction of the bottom wall of the inner card lane is respectively provided with a through inner card lane push rod groove extending along the length direction of the bifurcated card lane for the push rod of the second wire transmission system to pass through, so as to avoid the bottom wall of the inner card lane blocking the push rod of the second wire transmission system.

[0062] In addition, the winding forms of the first wire rope of the first wire transmission system and the second wire rope of the second wire transmission system are arbitrary. In this embodiment, the first wire rope and the second wire rope are wound on the same horizontal plane. The first card-pushing section of the first wire rope and the second card-pushing section of the second wire rope are both attached to the lower side of the mahjong table panel, so that the single-layer card push rod and the multi-layer card push rod can be aligned downward with the midline position in the width direction of their corresponding overall structure when pushing the cards. Therefore, the winding and installation methods of the wire ropes in the entire transmission system are simple and convenient, and there will be no torsional friction due to bending.

[0063] Both the single - layer card pushing slider and the multi - layer card pushing slider are elastic structures. Thus, the single - layer card pushing slider and the multi - layer card pushing slider can bend at the first driving wheel and the second driving wheel to rotate upward and downward, so as to drive the single - layer card pushing rod and the multi - layer card pushing rod to flip upward and downward at the corresponding driving wheels. Preferably, the single - layer card pushing slider and the multi - layer card pushing slider are elastic plastic square sliders, and the elastic plastic square sliders are placed in a slider groove, thereby ensuring that the movement track of the pushing slider is exactly the same as the shape of the card track. In this embodiment, since the first wire transmission system and the second wire transmission system are arranged directly above the bifurcated card track, the slider groove is arranged at the bottom of the table board, which is an inverted slider groove, and the shape of the slider groove coincides with the curvature, slope, and angle of the bifurcated card track. Thus, the single - layer card pushing rod and the multi - layer card pushing rod can maintain a relatively small spacing distance from their corresponding card tracks, and further ensure that all mahjong cards can be pushed.

[0064] The first driving wheel is located at the bifurcation position of the bifurcated card track, the second driving wheel is located at the entrance end of the bifurcated card track, and the first driven wheel and the second driven wheel are respectively located at the two exit ends of the bifurcated card track (i.e., the exit ends of the outer card track and the inner card track), so that the single - layer card pushing rod and the multi - layer card pushing rod can both achieve transmission between the entrance end and the exit end of the bifurcated card track.

[0065] In this embodiment, the first wire transmission system and the second wire transmission system further include the same driving motor fixedly installed on the frame through a flange. The driving motor has an output shaft extending in the horizontal direction perpendicular to the total card track. The output shaft of the driving motor is in transmission connection with one of the first driving wheel and the second driving wheel, and the first driving wheel and the second driving wheel are in transmission connection through a third steel wire rope, so as to realize the simultaneous transmission of the first wire transmission system and the second wire transmission system.

[0066] In this embodiment, the first wire transmission system and the second wire transmission system are completely simultaneously driven. Therefore, through the position setting of the pushing rod on the wire rope, when the pushing rod of the second wire transmission system reaches the bifurcation position of the bifurcated card track, the pushing rod of the wire transmission system flips downward at its corresponding driving wheel and moves along the outer card track.

[0067] The materials of the first steel wire rope and the second steel wire rope are plastic - coated steel wire ropes formed by wrapping a layer of plastic outside stainless steel wires, so they are firm and durable and not easily damaged. Preferably, the first steel wire rope and the second steel wire rope are wound around the driving wheels and the driven wheels for multiple turns to increase the friction force.

[0068] The single-layer card pushing rod is used to push a single mahjong card at the bottom of the three-layer mahjong cards. The multi-layer card pushing rod is used to push all three-layer mahjong cards in the main card track and push the top two-layer mahjong cards in the inner card track. The single-layer card pushing rod and the multi-layer card pushing rod are respectively injection-molded into one body with the single-layer card pushing slider and the multi-layer card pushing slider (i.e., the pushing sliders of the first and second wire transmission systems). Before the card pushing and card splitting operations, the single-layer card pushing slider and the multi-layer card pushing slider are respectively hidden in the non-card pushing sections of the first steel wire rope and the second steel wire rope. When the card pushing instruction is obtained, the second driving motor first drives the second driving wheel to rotate, and then drives the second steel wire rope to rotate, so that the multi-layer card pushing rod is transmitted to the second card pushing section of the second steel wire rope, and then the card pushing and card splitting actions of the mahjong cards are completed. When the second driving motor drives the multi-layer card pushing rod (i.e., the pushing rod of the second wire transmission system) to reach the bifurcation position of the bifurcation card track, the card splitting is realized at this time. Another transmission system is required to push the mahjong cards at the bottom layer. Therefore, the first driving motor is started to drive the first driving wheel to rotate, and then drive the first steel wire rope to rotate, so as to drive the single-layer card pushing rod to turn downward to the first card pushing section of the first steel wire rope and move along the outer card track. Thus, the card pushing and card splitting actions of the mahjong cards are completed.

[0069] The single-layer card pushing rod and the multi-layer card pushing rod are arranged to be able to be simultaneously transmitted to the outlet end of the bifurcation card track through the transmission of the first steel wire rope and the second steel wire rope, so that the card pushing actions of the single-layer card pushing rod and the multi-layer card pushing rod are synchronous.

[0070] In this embodiment, the working principle of the eight-opening mahjong machine for upright mahjong cards is as follows:

[0071] The three-layer mahjong cards are on the main card track. The driving motor rotates forward to drive the fine steel wire rope, and then drives the pushing rod on the pushing slider to move along the length direction of the card track until it is pushed to the position of the automatic card splitting port. At this time, the upper two-layer mahjong cards automatically enter the inner card track under the push of the pushing rod and finally move forward and rise to the tabletop; the lower one-layer mahjong cards automatically enter the outer card track and thus enter the 90-degree turning track of the outer card track. After the mahjong cards are turned 90 degrees through the 90-degree turning track, they enter the upright track 123 in an upright manner. Thus, under the push of the pushing rod, thirteen upright starting mahjong cards move forward to the tabletop to realize the entertainment of playing cards without manual card turning.

[0072] The eight-opening mahjong machine with upright mahjong tiles of the present invention is provided with a 90-degree twisting track in the outer tile track. From its starting point, the bottom wall of the 90-degree twisting track gradually changes from horizontal to inclined and finally gradually changes to vertical, and one side wall gradually changes from vertical to inclined and finally gradually changes to horizontal, so that the mahjong tiles are twisted by 90 degrees and then enter the upright track. As a result, when the starting mahjong tiles rise to the tabletop, they have already been erected, avoiding the need to push or flip the tiles by hand before playing for entertainment. Since the starting mahjong tiles have been erected, one can immediately start playing for entertainment. The present invention enables the eight-opening mahjong machine to erect thirteen mahjong tiles, which is a first in the mahjong machine market at home and abroad.

[0073] The above are only the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various changes can be made to the above embodiments of the present invention. That is, all simple, equivalent changes and modifications made in accordance with the claims and the content of the specification of the present invention application fall within the scope of protection of the claims of the present invention patent. Those not described in detail in the present invention are all conventional technical contents.
