[0001] The invention relates to the field of mahjong machines, in particular to a one-machine double-card pushing device for an eight-mouth mahjong machine. Background Art

[0002] In the domestic and foreign mahjong machine markets, mahjong machines usually use one motor to push the cards to a specified number, and then another motor cooperates to raise the cards to the table. Two motors are used to complete the task of pushing the cards to the table - for entertainment and playing cards.

[0003] The problem with this design is that it requires a relatively large number of motors to make an eight-mouth mahjong machine, which increases the production cost, and the number of motors makes it impossible to further reduce the size of the eight-mouth mahjong machine. In addition, since the current mahjong machine usually uses a chain belt transmission method, the chain belt needs to be frequently tightened and adjusted during use, so its stability needs to be further improved.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0032] Combine the following Figure 1-Figure 3 The preferred embodiments of the present invention are described in detail.

[0033] Figure 1-Figure 3 The present invention shows a one-machine dual-card push device for an eight-mouth mahjong machine. Figure 1 and Figure 2 As shown, the push card motion device of the eight-mouth mahjong machine of the present invention comprises a frame 1, and the frame 1 is provided with a forked guide rail with a split card turnout point, and the forked guide rail has a common straight line overlap guide rail 11, and the arc-shaped first guide rail 12 and the second guide rail 13 that fork and extend from the outlet end of the overlap guide rail 11, and the first guide rail 12 is located at the inner side of the second guide rail 13 (that is, the first guide rail 12 is the inner card road on the right side of the figure, and the second guide rail 13 is the outer card road on the left side of the figure). Therefore, the entrance end of the overlap guide rail 11 is the entrance end of the forked guide rail, and the outlet ends of the first guide rail 12 and the second guide rail 13 are respectively two outlet ends of the forked guide rail. In the present embodiment, the shape of the first guide rail 12 on the horizontal plane is a circular arc curve of a first radius, and the shape of the second guide rail 13 on the horizontal plane is a combination of a circular arc curve of a second radius and a straight line, and the first radius is greater than the second radius. In other embodiments, the first guide rail 12 and the second guide rail 13 can also adopt other forms of arc forms. In addition, the depth of the first guide rail 12 at the bifurcation position is greater than the depth of the second guide rail 13 at the bifurcation position, so in order to make the first guide rail 12 and the second guide rail 13 equal in height at their respective exit ends, the portion of the first guide rail 12 downstream of the bifurcation position is an upward slope with a gradually decreasing depth. Thus, the mahjong tiles can slide along the bifurcation rail to achieve pushing and splitting. The material of the frame 1 is conventional plastic, for example, the material can be polyoxymethylene.

[0034] The bottom of the bifurcated guide rail is provided with two square grooves (i.e., the first square groove 14 and the second square groove 15) with tops spaced apart from each other. Spaced apart from each other here means that the first square groove 14 and the second square groove 15 have neither overlapping parts nor crossing; the square grooves here are also referred to as square groove frames hereinafter. In this embodiment, the first square groove 14 is arranged at the bottom of the overlapping guide rail 11 and the first guide rail 12, close to the right side of the track, and the second square groove 15 is arranged at the bottom of the overlapping guide rail 11 and the second guide rail 12, close to the left side of the track.

[0035] The first square groove 14 and the second square groove 15 are only open at the top, and the other three sides are closed, that is, the first square groove 14 and the second square groove 15 have space for the track of the push card rod to be described in detail below, and the size slightly looser than the push card rod diameter is fine. The first square groove 14 is accommodated with the first elastic square rod 101, and the second square groove 15 is accommodated with the second elastic square rod 201, so that the first elastic square rod 101 and the second elastic square rod 201 can slide along the extension direction of the first square groove 14 and the second square groove 15 respectively. In the present embodiment, the cross section of the first elastic square rod 101 and the second elastic square rod 201 is rectangular, and the material of the first elastic square rod 101 and the second elastic square rod 201 is oily polyoxymethylene, thereby forming an elastic square plastic rod. A bottom layer card pushing rod 104 and an upper layer card pushing rod 204 are respectively provided at the front ends of the first elastic square rod 101 and the second elastic square rod 201, and the size of the openings at the tops of the first square groove 14 and the second square groove 15 are slightly larger than the bottom layer card pushing rod 104 and the upper layer card pushing rod 204, so that the pushing rods can slide along the openings at their tops as the first elastic square rod 101 and the second elastic square rod 201 slide in the first square groove 14 and the second square groove 15.

[0036] The first square groove 14 extends along the extension direction of the overlapping guide rail 11 and the first guide rail 12, and the first square groove 14 extends from the entrance end of the overlapping guide rail 11 to the exit end of the first guide rail 12, so that the two ends of the first elastic square rod 101 extend horizontally from the entrance end of the overlapping guide rail 11 and the exit end of the first guide rail 12 respectively, thereby enabling the bottom card pushing rod 104 to push the mahjong cards to slide along the guide rails to the exit end of the first guide rail 12 starting from the entrance end of the overlapping guide rail 11.

[0037] The second square groove 15 extends along the extension direction of the overlapping guide rail 11 and the second guide rail 13, and the second square groove 15 extends from the upstream of the bifurcation position of the bifurcated guide rail to the exit end of the second guide rail 13, and the second square groove 15 is provided with a bottom channel (not shown) extending downward and finally penetrating the frame 1 at its starting position (i.e., upstream of the bifurcation position) to form a downward channel for one end of the second elastic square rod 201 to extend downward, and the other end of the second elastic square rod 201 to extend horizontally from the exit end of the second guide rail 13, thereby enabling the upper card pushing rod 204 of the mahjong tiles below the frame 1 to be flipped upward from the bottom channel at the starting position of the second square groove 15, and push the mahjong tiles to slide along the guide rail to the exit end of the second guide rail 13.

[0038] In this embodiment, the bottom layer card push pin rod 104 and the upper layer card push pin rod 204 are respectively arranged in the middle of the surface of the first elastic square rod 101 and the second elastic square rod 201, the height of the bottom layer card push pin rod 104 is lower than the thickness of a mahjong tile, the height of the upper layer card push pin rod 204 is between the thickness of two and three mahjong tiles, and the bottom layer card push pin rod 104 and the upper layer card push pin rod 204 are respectively injection molded into one piece with the first elastic square rod 101 and the second elastic square rod 201. Thus, the bottom layer card push pin rod 104 and the upper layer card push pin rod 204 are configured to push three layers of mahjong tiles on the overlapping guide rail 11 and push two layers of mahjong tiles on the second guide rail 13.

[0039] like Figure 1 and Figure 2 As shown, the card pushing motion device of the eight-mouth mahjong machine also includes a drive motor 2 fixedly mounted on the frame 1 through a flange, and the drive motor 2 has an output shaft 21. A motor gear 102 is sleeved on the output shaft 21, so that the output shaft 21 is transmission-connected with the motor gear 102. Preferably, the output shaft 21 of the drive motor 2 is transmission-connected with the motor gear 102 in an interference fit manner to prevent the instability of the transmission. The drive motor 2 is configured to rotate in both positive and negative directions.

[0040] like Figure 2 As shown, in this embodiment, the bottom surface of the first elastic square rod 101 is provided with first holes 1031 evenly arranged along the entire length direction of the first elastic square rod 101, and the output shaft 21 is located directly below the entrance end of the bifurcated guide rail of the frame 1 (i.e., the entrance end of the overlapping guide rail 11), so that the output shaft 21 is directly opposite to the surface where the first hole 1031 is located. The motor gear 102 is located at the entrance end of the bifurcated guide rail of the frame 1, and it meshes with the first hole 1031 on the bottom surface of the first elastic square rod 101, so that the motor gear 102 can drive the first elastic square rod 101 to move forward or backward (i.e., along a direction perpendicular to Figure 2 In addition, the frame 1 is provided with a corresponding window at a position corresponding to the motor gear 102, so that the bottom surface of the first elastic square rod 101 is exposed relative to the first square groove 14, so that the motor gear 102 and the first elastic square rod 101 can mesh with each other. In this embodiment, the motor gear 102 is a pointed gear (i.e., a cylindrical gear with a cone-shaped tooth shape, and the cone tip is radially outward), so that the motor gear 102 and the first elastic square rod 101 can mesh with each other. The pointed gear is also referred to as a bevel gear hereinafter. In the present invention, the bevel gear is not a circular bevel gear commonly referred to in the prior art.

[0041] However, in other embodiments, the first elastic square rod 101 is provided with first flat teeth instead of first holes, and the motor gear 102 is a conventional cylindrical gear with flat teeth, so that the motor gear 102 and the first flat teeth can mesh with each other.

[0042] In addition, in other embodiments, the first hole 1031 can also be set on the top surface or side surface of the first elastic square rod 101, and the output shaft 21 is opposite to the surface where the first hole 1031 is located, so that the motor gear 102 and the first hole 1031 of the first elastic square rod 101 can engage with each other.

[0043] like Figure 3 As shown, the bottom surfaces of the first elastic square rod 101 and the second elastic square rod 201 are respectively provided with second holes 1032 and third holes 2032 evenly arranged along the entire length direction of each, and the third hole 2032 is located at the splitting point of the bifurcated guide rail. The first elastic square rod 101 and the second elastic square rod 201 are respectively meshed with the driving bevel gear 105 and the driven bevel gear 205 through the second hole 1032 and the third hole 2032; the driving bevel gear 105 and the driven bevel gear 205 are coaxially fixedly connected through a transmission shaft 4, so that the rotation of the driving bevel gear 105 can directly drive the driven bevel gear 205 to rotate synchronously. In some embodiments, the second hole 1032 may just coincide with the first hole 1031.

[0044] Thus, the first elastic square rod 101 that is driven by the motor to actively move along the length direction drives the active pointed gear 105 to rotate, and then the active pointed gear 105 drives the driven pointed gear 205 to rotate, and finally the driven pointed gear 205 drives the second elastic square rod 201 to move along the length direction of the second elastic square rod 201.

[0045] Among them, the wheel diameter of the active pointed gear 105 is smaller than the wheel diameter of the driven pointed gear 205, so that the distance that the driven pointed gear 205 drives the second elastic square rod 201 to move is greater than the distance that the active pointed gear 105 moves with the first elastic square rod 101, thereby meeting the demand for a longer moving distance required by the outer card track.

[0046] See also Figure 1 and Figure 3 The driving pointed gear 105 and the driven pointed gear 205 are both arranged on the overlapping guide rail 11, preferably at a dividing switch point at the exit position of the overlapping guide rail 11.

[0047] In addition, the frame 1 is provided with corresponding windows at positions corresponding to the driving pointed gear 105 and the driven pointed gear 205, so that the first elastic square rod 101 is exposed relative to the first square groove 14, and the second elastic square rod 201 is exposed relative to the second square groove 15, so that the driving pointed gear 105 and the first elastic square rod 101, and the driven pointed gear 205 and the second elastic square rod 201 can mesh with each other.

[0048] In this embodiment, the transmission shaft 4 is fixed to the frame 1 through a bearing, so that the transmission shaft 4 can rotate relative to the frame 1. In other embodiments, the transmission shaft 4 can also be fixed at other positions.

[0049] It should be noted that the driving pointed gear 105 and the driven pointed gear 205 are pointed gears, that is, cylindrical gears with cone-shaped teeth, and the cone tips are radially outward.

[0050] Therefore, the present invention implements the following principles and working procedures through the above structure.

[0051] Mechanical mechanism principle:

[0052] Material: Elastic square plastic rod (Note: There is a push rod in front of the square plastic rod, referred to as square plastic rod) with holes or flat teeth on all four sides. Under the rotation of the motor gear, it is pushed into the plastic square slot frame closed on three sides. There is space for the push rod track facing upward, which is slightly looser than the diameter of the push rod. There should be a moderate gap between the square plastic rod and the square slot frame. The square plastic rod can move forward and backward arbitrarily in the sloped and curved square slot frame. The motor is pushed forward when it is forward, and it is reversed when it is reversed to the original point (swimming in and out like a snake).

[0053] Two-tooth synchronous linkage bridge transmission:

[0054] Procedure (I)

[0055] When the square plastic cards are pushed to the third layer of 12 tons with 36 cards, the main force is still the right inner card track. The hole of the square plastic rod in the square slot frame drives the bevel gear under a window to rotate, and at the same time drives the bevel gear under the outer card track to rotate, and at the same time drives the hole of the square plastic rod in the window under the outer card track to rotate to advance or reverse the transmission (the outer card track is slightly longer than the inner card track by a few centimeters, adjusted by the difference in wheel diameter).

[0056] Procedure (II)

[0057] Three layers of 12 cards are pushed to the dividing point. The bottom layer of 12 cards, totaling 12 cards, automatically enters the outer left card track. The upper two layers of 12 cards, totaling 24 cards, automatically enter the inner right card track. At the same time, double cards are pushed to the table on the slope - entertainment card playing (a full set of 144 cards for four people on four sides).

[0058] The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The above embodiment of the present invention can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the description of the present invention fall within the scope of protection of the claims of the present invention. The contents not described in detail in the present invention are all conventional technical contents.
