It includes a grid plate, a tile-pushing bracket mounted on the grid plate, a tile-pushing assembly that moves linearly along the bracket, and a tile-pushing swing rod and a return spring acting on the tile-pushing assembly. The top of the grid plate is a stacking platform, with a tile-supporting plate at its front. The tile-pushing bracket is located at the rear of the grid plate. The swing end of the tile-pushing swing rod abuts against the tile-pushing assembly, and the tile-pushing assembly is connected to the rear end of the tile-pushing bracket via a return spring. The return spring is inclined relative to the movement path of the tile-pushing assembly. The tile-pushing assembly includes a flat-push slider and a tile-pushing plate mounted on the flat-push slider. The flat-push slider is linearly connected to the tile-pushing bracket via a guide rod. The return spring is inclined relative to the guide rod.

[0003] In the prior art, the guide rod used to limit the sliding block from extending into the card pusher bracket requires that a sufficient gap be maintained between the side panel of the mahjong machine and the card pusher, resulting in a larger overall machine size. Utility Model Content

[0004] In order to solve the problem of the large size of mahjong machines in the prior art, the purpose of this utility model is to provide a flat-push tile-loading mechanism for mahjong machines, which requires less movement space and thus makes the overall size of the machine smaller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flat-push tile-feeding mechanism for a mahjong machine, comprising a tile-feeding seat, a flat-push slider disposed on the tile-feeding seat, and a tile-pushing assembly for driving the flat-push slider to move in a straight line. The tile-pushing assembly includes a tile-pushing bracket and a tile-pushing plate mounted on the flat-push slider. A guide groove is provided on the tile-pushing bracket, and the bottom of the flat-push slider matches the guide groove, with the bottom of the flat-push slider extending into the guide groove and slidingly engaging. A tile-pushing swing rod is rotatably mounted on the tile-feeding seat and connected to the flat-push slider. When the tile-pushing swing rod rotates, it can drive the flat-push slider to move along the guide groove on the tile-pushing bracket.

[0006] Preferably, the sliding block has a connecting part that contacts the swing end of the pusher arm, the bottom of the pusher arm is hinged to the upper card holder, and a pusher cam is rotatably mounted on the upper part of the upper card holder. When the pusher cam rotates, it can push the pusher arm to swing forward. An elastic element is provided between the upper card holder and the pusher arm to drive the pusher arm to return to its original position.

[0007] Preferably, the roller is rotatably mounted on the swing end of the push bar, and a drive groove is provided on the connecting part of the flat push slider. The roller extends into the drive groove and can move up and down in the drive groove. The side of the roller can push against the inner wall of the drive groove to drive the flat push slider to move back and forth.

[0008] Preferably, the two drive slots are located on the left and right sides of the flat push slider, and the two push bar arms are located on the left and right sides of the flat push slider, respectively, with the two push bar arms connected to the two drive slots.

[0009] Preferably, the drive groove is a T-shaped groove, and the bottom of the flat push slider is provided with a T-shaped support foot, which matches the drive groove.

[0010] Preferably, a drive shaft is rotatably mounted on the upper card holder, and the bottom of the push card lever is fixedly connected to the drive shaft; the elastic element includes a torsion spring, which is sleeved on the drive shaft, with one leg of the torsion spring abutting against the upper card holder and the other leg abutting against the push card lever; a first connecting member 77 is fixed on the drive shaft, and the top of the first connecting member 77 is engaged with the push card cam drive.

[0011] Preferably, a second connector is fixed to the bottom of the push bar. The bottom of the second connector is sleeved and fixed on the transmission main shaft. An opening is provided at the front end of the second connector. The support leg on the rear side of the torsion spring extends into the opening of the second connector and presses the second connector down.

[0012] Preferably, two mounting seats are respectively fitted onto both ends of the transmission main shaft, the mounting seats and the transmission main shaft are rotatably engaged, and the mounting seats are fixedly connected to the rear end of the upper plate seat.

[0013] Preferably, the front part of the pusher bracket is a transition section, and the rear part is a positioning section. The guide groove extends through the transition section and the positioning section in the front-back direction. The stacking platform is divided into two sections. The transition section is located between the two stacking platforms. The pusher head is set at one end of the upper card holder. The pusher head pushes the mahjong tiles onto the stacking platform. The guide groove on the side of the pusher bracket and the flat pusher slider forms multiple bends at the top of the transition section. Among them, the bend on the upper part of the transition section facing the pusher head is an arc angle, and the bend on the pusher bracket facing away from the pusher head is a right angle.

[0014] Preferably, the card pusher is located between two stacking platforms, and the end of the stacking platform near the card pusher is provided with an avoidance gap, allowing the card pusher lever to freely move in and out of the avoidance gap from back to front.

[0015] The beneficial effects of the technical solution of this utility model are as follows: the guide groove defines the straight direction of the pusher component, and the movement stroke of the pusher bracket is restricted within the guide groove of the flat pusher slider, thereby eliminating the gap between the flat pusher slider and the side panel of the mahjong machine used to avoid the pusher bracket, thus reducing the overall size of the machine and making the mahjong machine smaller. With the same table size, larger mahjong tiles can be played; and the above-mentioned flat pusher mechanism requires fewer components, making the structure of the mahjong machine simpler.

Therefore, they should not be construed as limitations on this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

Example

[0036] like Figures 1 to 8 The illustrated mahjong machine's flat-push tile-loading mechanism includes a tile-loading base 1, a flat-push slider 3 mounted on the base 1, and a tile-pushing assembly that moves along the flat-push slider 3 in a linear direction. The top of the base 1 is a stacking platform 11, with a liftable tile-supporting plate 6 on the front side of the platform 11. The flat-push slider 3 is located at the rear of the base 1. The stacking mechanism in the mahjong machine stacks the mahjong tiles into piles and pushes them onto the stacking platform 11. The flat-push slider 3 pushes the stacked mahjong tiles onto the tile-supporting plate 6, which then lifts the tiles onto the mahjong table surface.

[0037] In this embodiment, as Figures 4 to 8 As shown, the card pusher assembly includes a card pusher bracket 2 and a card pusher plate 5 mounted on a flat pusher slider 3. The card pusher bracket 2 is provided with a guide groove 23, and the bottom of the flat pusher slider 3 matches the guide groove 23. The bottom of the flat pusher slider 3 extends into the guide groove 23 and slides in cooperation. The card pusher lever 4 is rotatably mounted on the upper card holder 1. The card pusher lever 4 is connected to the flat pusher slider 3. When the card pusher lever 4 rotates, it can drive the flat pusher slider 3 to move along the guide groove 23 on the card pusher bracket 2.

[0038] With this configuration, the guide groove defines the straight direction of the pusher assembly, and the travel of the pusher bracket is restricted within the guide groove of the flat pusher slider. This eliminates the gap between the flat pusher slider and the side panel of the mahjong machine used to avoid the pusher bracket, thereby reducing the overall size of the machine and making the mahjong machine smaller. With the same table size, larger mahjong tiles can be played. Furthermore, the pusher assembly requires fewer components, making the structure of the mahjong machine simpler.

[0039] In this embodiment, as Figure 4 and Figure 5As shown, the swing end of the pusher arm 4 abuts against the flat slider 3. Specifically, the flat slider 3 has a connecting part that contacts the swing end of the pusher arm 4. The bottom of the pusher arm 4 is hinged to the upper card holder 1. The upper part of the upper card holder 1 is rotatably mounted with a pusher cam 75. When the pusher cam 75 rotates, it can push the pusher arm 4 to swing forward. An elastic element 44 is provided between the upper card holder 1 and the pusher arm 4 to drive the pusher arm 4 to return to its original position.

[0040] Further preferred, such as Figures 4 to 6 As shown, the roller shaft is rotatably mounted on the swing end of the pusher arm 4. A drive groove 32 is provided on the connecting part of the flat pusher slider 3. The roller shaft extends into the drive groove 32 and can move up and down within the drive groove 32. The side of the roller shaft can push against the inner wall of the drive groove 32 to drive the flat pusher slider 3 to move back and forth. With this configuration, the roller shaft rolls against the pusher bracket 2, reducing friction and noise when the pusher arm 4 pushes the pusher bracket 2. There is no need to install other structures to restrict the roller shaft on the pusher bracket, thus simplifying the structure of the pusher assembly.

[0041] In a further preferred embodiment, the two drive slots 32 are respectively located on the left and right sides of the flat sliding block 3, and the two card-pushing swing arms 4 are respectively located on the left and right sides of the flat sliding block 3, with the two card-pushing swing arms 4 connected to the two drive slots 32 respectively. This arrangement enables the card-pushing bracket to move more smoothly.

[0042] More preferably, the drive groove 23 is a T-shaped groove, and the bottom of the flat push slider 3 is provided with a T-shaped support 31, which matches the drive groove 23.

[0043] In this embodiment, as Figure 2 and Figure 5 As shown, a transmission main shaft 43 is rotatably mounted on the upper card holder 1. The bottom of the push card lever 4 is fixedly connected to the transmission main shaft 43. The elastic element 44 includes a torsion spring, which is sleeved on the transmission main shaft 43. One leg of the torsion spring abuts against the upper card holder 1, and the other leg of the torsion spring abuts against the push card lever 4. A first connecting member 77 is fixed on the transmission main shaft 43, and the top of the first connecting member 77 is in transmission cooperation with the push card cam 75.

[0044] When the card is placed, the card-pushing lever 4 pushes the card-pushing assembly forward, causing the torsion spring to deform. After the card is placed, the restoring force of the torsion spring can drive the card-pushing assembly to return to its original position. At the same time as the card-pushing bracket 2 moves backward, the front baffle of the connecting part on the card-pushing bracket 2 drives the card-pushing lever 4 to return to its original position.

[0045] In this embodiment, as Figure 5As shown, a second connector 41 is fixed at the bottom of the push bar 4. The bottom of the second connector 41 is sleeved and fixed on the transmission main shaft 43. An opening 42 is provided at the front end of the second connector 41. The support leg on the rear side of the torsion spring extends into the opening 42 of the second connector 41 and presses the second connector 41 down.

[0046] In this embodiment, as Figure 2 and Figure 5 As shown, two mounting seats 45 are respectively sleeved on both ends of the transmission main shaft 43. The mounting seats 45 and the transmission main shaft 43 are rotatably engaged, and the mounting seats 45 are fixedly connected to the rear end of the upper plate seat 1.

[0047] In this embodiment, as Figure 7 and Figure 8 As shown, the front part of the pusher bracket 2 is a transition section 22, and the rear part is a positioning section 21. The guide groove 23 extends in the front-to-back direction, penetrating the transition section 22 and the positioning section 21. The stacking platform 11 is divided into two sections, with the transition section 22 located between the two stacking platforms 11. The pusher head is set at one end of the upper tile holder 1, pushing the mahjong tiles onto the stacking platform 11. The guide groove on the side of the pusher bracket 2 and the flat pusher slider forms multiple bends at the top of the transition section. Among them, the bend on the transition section 22 facing the pusher head is a rounded angle, and the bend on the pusher bracket 2 facing away from the pusher head is a right angle. This design allows the mahjong tiles to pass smoothly through the flat pusher slider, ensuring the stable operation of the mahjong machine.

[0048] Further preferred, such as Figure 8 As shown, the stacking platform 11 has an obstacle clearance 12 at one end near the card pusher bracket 2, and the card pusher lever 4 can freely move in and out of the obstacle clearance 12 from back to front.

[0049] In order to achieve the card-pushing action, in this embodiment, as follows: Figures 1 to 5 As shown, a card-raising motor 7 is installed on the card-raising base 1. The card-raising motor 7 is connected to four gears that mesh sequentially on the card-raising base 1. Among the four gears, the card-raising motor 7 is connected to one gear, and the card-raising cam 75 is connected to another gear through the transmission shaft 74. The card-pushing cam 75 pushes the card-pushing swing arm 4 to swing forward.

[0050] More preferably, the four gears are a first gear 71, a second gear 76, and two third gears 72. The first gear 71, the second gear 76, and the third gears 72 are all rotatably mounted on the front side of the upper plate holder. The first gear 71 and the second gear 76 mesh with each other. The first gear 71 and the second gear 76 are positioned between the two third gears 72. One third gear 72 meshes with the first gear 71, and the other third gear 72 meshes with the second gear 76.

[0051] The card-mounting motor 7, card-mounting cam 75, and transmission main shaft 43 are located on the rear side of the card-mounting base 1. The card-mounting motor 7 is connected to the first gear 71, the card-mounting cam 75 is connected to the second gear 76, and the front ends of the two third gears 72 are fixed with lifting cranks 73. A support frame 61 is provided under the card-mounting plate 6. The bottom cam curve 62 of the support frame 61 is engaged with the lifting crank 73. The third gear 72 can drive the card-mounting plate 6 to move up and down through the lifting crank 73.

[0052] In this embodiment, a guide sleeve 63 is fixed to the front end of the upper card holder 11, and a guide rod 64 is fixed to the bottom of the card support plate 6. The guide rod 64 is inserted into the guide sleeve 63 and slides in cooperation with it.
