Description
Technical Field
[0001] The utility model relates to the field of mahjong machines, in particular to a card pushing and raising device. Background Art
[0002] The card pushing and lifting device pushes the mahjong tiles in the annular card storage slot onto the card lifting board, and the card lifting board then lifts the mahjong tiles onto the tabletop of the mahjong machine. Therefore, this structure is the main structure of the rotor-type mahjong machine. Currently, the older technology on the market is that the card lifting board is driven by a motor to rise and fall, and another motor is used to drive when pushing the cards. This structure is costly and bloated.
[0003] In order to overcome the defects of the above-mentioned technology, there is also a structure on the market that uses a motor to simultaneously control the movement of the card lifting plate and the card pushing rod, such as the announcement number CN 110237527 A card storing and lifting device according to claim 1, which uses a power motor to simultaneously drive a card loading mechanism and a card lifting mechanism, the card loading mechanism includes a turntable and a power motor driving the turntable to rotate, the card lifting mechanism includes a card lifting plate and a transmission mechanism driving the card lifting plate to rise and fall, the turntable is provided with a door opening annular slide groove located in the inner circle and a door closing annular slide groove located in the outer circle, a first bridging slide groove is provided between the head end of the door opening annular slide groove and the head end of the door closing annular slide groove, a second bridging slide groove is provided between the tail end of the door opening annular slide groove and the tail end of the door closing annular slide groove, and also includes a slider connected to the transmission mechanism and a spring for applying force to the slider, the slider passes through the first bridging slide groove or the second bridging slide groove and enters and stays in the door opening annular slide groove or the door closing annular slide groove when the turntable rotates forward and backward and under the force of the spring, thereby driving the transmission mechanism to drive the card lifting plate to maintain the door opening state or the door closing state.
[0004] Although the above patent discloses that the turntable is driven to rotate by a power motor, the turntable drives the card-lifting mechanism to rise and fall through the transmission mechanism, and the lifting of the card-lifting mechanism is achieved by the forward and reverse rotation of the power motor. The forward rotation of the power motor drives the turntable to rotate, and the card-lifting plate slides in the door-opening annular slide groove through the transmission mechanism, and the card-lifting plate descends to the card-lifting track, and the turntable drives the card head to push all the mahjong cards onto the card-lifting plate; the reverse rotation of the power motor drives the turntable to reverse, and the card-lifting plate slides in the door-closing annular slide groove through the transmission mechanism, and the card-lifting plate rises to the mahjong machine table, and at this time the card-pushing head also moves in the opposite direction to the original position. On the one hand, this structure increases the control of the motor, and the control program is complicated; on the other hand, the forward and reverse rotation of the turntable drives the first bearing to move too long.

[0043] The following is combined with Figure 1-6 The utility model is further described in detail with examples.
[0044] Example 1
[0045] The card pushing and raising device comprises a card storage rack 10, a turntable assembly installed on the card storage rack 10, a motor 11 installed on the card storage rack 10 and driving the turntable assembly to rotate, a card raising plate 12 hinged on the card storage rack 10, and a connecting rod assembly installed on the card storage rack 10 and driving the card raising plate 12 to rise and fall. The card storage rack 10 is used to store mahjong cards, and the motor 11 drives the turntable assembly to rotate, thereby realizing the lifting and falling of the card raising plate 12 and pushing the mahjong cards onto the card raising plate 12. The turntable assembly includes an inner turntable 13, an outer turntable 14 and a gear ring 15. The gear ring 15 is fastened to the outer turntable 14 by screws and the inner turntable 13 is axially limited on the outer turntable 14. The inner turntable 13 is limited between the gear ring 15 and the outer turntable 14. The inner turntable 13 can rotate relatively on the outer turntable 14. A pusher rod 21 that rotates synchronously with the ring gear 15 is installed on the ring gear 15. The pusher rod 21 is used to push the mahjong cards and push them onto the card raising plate 12. In this embodiment, the pusher rod 21 is integrally formed on the gear ring 15;
[0046] The output shaft of the motor 11 is provided with a driving gear 16 which can drive the gear ring 15 and the inner turntable 13. When the card raising plate 12 raises the cards and the card pushing rod 21 pushes the cards, the motor 11 only moves in one direction, the driving gear 16 rotates and drives the outer turntable 14 and the inner turntable 13 to rotate. The motor 11 in the device can raise the cards on the card raising plate 12 and push the cards on the card pushing rod by moving in one direction, so that the program for controlling the motor 11 does not need to be too complicated.
[0047] A circular track 131 is provided on the end surface of the inner turntable 13, and the connecting rod assembly moves along the track 131 and drives the card lifting plate 12 to rise and fall. After the connecting rod assembly moves one circle along the track 131, the card lifting plate 12 and the card pushing rod 21 can be reset. The stroke for lifting the card lifting plate 12 to the table top and the card pushing rod 21 to move to the starting position is short, thereby improving the stability of the device movement.

The track 131 includes a descending track section 1311, a card pulling track section 1312 and an ascending track section 1313 connected in sequence. When the roller 20 moves in the descending track section 1311, the connecting rod assembly drives the end of the card raising plate 12 to descend to the card storage slot 101; the card pulling track section 1312 is on the same circumference, and when the roller 20 moves in the card pulling track section 1312, the end of the card raising plate 12 is connected to the card storage slot 101, and the mahjong tiles can be pushed onto the card raising plate 12 when the card pushing rod 21 pushes the tiles; when the roller 20 moves in the ascending track section 1313, the connecting rod assembly drives the end of the card raising plate 12 to rise to a horizontal position, and the card raising plate 12 lifts the mahjong tiles onto the mahjong machine table. The track 131 is a special-shaped track, and an annular track 131 can realize the lifting and lowering of the card raising plate 12 and the pushing of the card pushing rod 21.
[0050] The track 131 also includes a reset track section 1314 disposed between the descending track section 1311 and the ascending track section 1313. When the roller 20 moves from one end of the reset track section 1314 to the other end, the connecting rod assembly does not drive the lifting plate 12 to move.

The outer turntable 14 rotates synchronously with the inner turntable 13. The top block 22 moves to the position of the first inner convex portion 135 and abuts against the first inner convex portion 135, so that the inner turntable 13 and the outer turntable 14 form a relative movement. At this time, the driving gear 16 is meshed with the first tooth portion 152 of the ring gear 15, and the driving gear 16 is disengaged from the second tooth portion 134 of the inner turntable 13 and enters the second toothless portion 133.
[0053] The upper end surface of the inner turntable 13 is provided with a limit groove 136 with an arc shape and the number is at least one. In this embodiment, the number of the limit grooves 136 is two and they are evenly distributed on the inner turntable 13. The inner end surface of the outer turntable 14 is integrally formed with a limit block 141 that can slide relatively on the limit groove 136. The outer turntable 14 drives the inner turntable 13 to rotate synchronously through the limit block 141 that contacts the end wall of the limit groove 136.

The limiting block 141 also moves relatively to abut against the end wall of the limiting groove 136, and the outer turntable 14 drives the inner turntable 13 to rotate synchronously. At the same time, the top block 22 passes over the first inner convex portion 135 through the first outer convex portion 142 and falls into the limiting groove 136. When the top block 22 moves on the first inner convex portion 135 and the first outer convex portion 142, the outer turntable 14 rotates synchronously with the inner turntable 13.
[0056] The inner turntable 13 is provided with a second inner convex portion 137 for compressing the top block 22. The second inner convex portion 137 and the first inner convex portion 135 are on the same circumference. One end of the second inner convex portion 137 is provided with a second inclined surface 1371 for guiding the top block 22 to escape from the second outer convex portion 143.
