Description

Technical Field

[0001] The invention relates to the field of mahjong machines, and in particular to a card pushing device and a mahjong machine thereof. Background Art

[0002] After more than 20 years of development, the technology of automatic mahjong machines is becoming more and more mature. The improvement of mahjong machines is getting smaller and smaller. For traditional non-roller coaster mahjong machines, the structure of the card pushing and lifting device is basically the same as the technical solution disclosed in patent application No. 201811294157.4. When pushing cards, the card driving motor 2-1 starts and drives the driving gear 2-2 to rotate, the driving gear 2-2 rotates and drives the output gears on both sides to rotate, the output gear drives the cam to rotate, and the card pushing rocker arm 5-3 moves relatively along the ascending surface or descending surface on the cam 5-2 through the bearing 5-3-1, so that the card pushing rocker arm 5-3 swings back and forth, and the card pushing rocker arm 5-3 pushes the card pushing plate 6 to move back and forth and pushes the mahjong machine cards to the lifting plate 4. The card pushing and lifting device of this structure is complex in structure and has high processing cost. The pushing distance of the push plate is determined by the trajectory of the ascending surface or descending surface on the cam 5-2. When the cam is assembled in the device, the pushing distance of the push plate is inconvenient to adjust, which makes the use range of the push-up device relatively limited and cannot push different types of mahjong tiles. Summary of the invention

[0003] The present invention aims to provide a card pushing and lifting device and a mahjong machine thereof in view of the shortcomings of the prior art card pushing and lifting device, such as complex structure, high manufacturing cost and difficulty in adjustment.

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0005] A card lifting device comprises a card receiving seat, one side of which is equipped with a motor and a card pushing plate, and the other side of which is equipped with a rocker arm for lifting the card lifting plate assembly to a tabletop, the output shaft of the motor passes through the card receiving seat and is connected to the rocker arm; it also comprises a card pushing bracket and a spring, the lower end of the card pushing bracket is hinged on the card receiving seat, one end of the card pushing bracket is fixed on the card pushing plate, and the other end of the card pushing bracket passes around the bottom of the card receiving seat and is connected to the other side of the card receiving seat through a spring, the card pushing bracket on the same side of the rocker arm is set as a driving part, the driving part is provided with a protruding block protruding upwards, the end face of the protruding block is an arc-shaped track surface, a pressure rod is installed on the rocker arm, when the card pushing plate pushes a card, the rocker arm rotates and drives the pressure rod to move to the driving part, the pressure rod presses the driving part down along the arc-shaped track surface, and the other end of the card pushing bracket tilts upwards and pushes the card pushing plate to move.

[0006] The card pushing and lifting device realizes the movement of the card pushing plate through the principle of a seesaw, eliminates the driven gear and cam structure in the traditional card pushing plate, simplifies the structure of the card pushing and lifting device, and reduces the manufacturing cost. The card pushing bracket of the device is a seesaw, and the card pushing bracket is hinged on the card bearing seat. One end of the card pushing bracket is fixed on the card pushing plate, and the other end is installed under the rocker arm through a spring. When working, the rocker arm drives the card lifting plate assembly to descend, and at the same time, the pressure rod on it will press down the driving part, and the card pushing bracket at the end of the card pushing plate will be pressed up, thereby pushing the card pushing plate. When the pressure rod is pressed down, it moves along the arc track surface of the protrusion, ensuring the linear push of the card pushing plate, so that the mahjong cards can be smoothly pushed to the card lifting plate assembly.

[0007] Preferably, the card pushing bracket on the same side as the card pushing plate is set as the card pushing part, and the card pushing part is fixedly connected to the driving part through a connecting part, and the connecting part is hinged on the card receiving seat through a pin shaft.

[0009] Preferably, the card pushing part is a card pushing rod, and card pushing rods are fixed at both ends of the connecting part, and a connecting rod is fixed between the two card pushing rods.

[0010] The two card pushing rods push the card pushing board at the same time, so that the forces on both ends of the card pushing board are even, and the card pushing board will not tilt to push the mahjong tiles, thereby ensuring that the card pushing board can push all mahjong tiles at the same time.

[0011] Preferably, a first notch is provided at the lower end of the card receiving seat for the card pushing bracket to pass through, and the connecting part is installed in the first notch, and its two ends are hinged on the first notch wall.

[0012] The first notch facilitates installation of the card pusher bracket so that the card pusher does not protrude from the lower end surface of the card holder. Otherwise, people need to process installation grooves or holes on the bottom plate where the card holder is placed.

[0013] Preferably, both ends of the connecting portion are fixed with connecting blocks, which are hinged to the first notch wall through a pin shaft. The connecting blocks facilitate the hinge connection of the card pusher bracket to the card holder, which is convenient for installation.

[0014] Preferably, a connecting seat protruding horizontally outward is installed on the card receiving seat on the same side as the card pushing plate, and a limit block for limiting the resetting of the card pushing plate is installed on the connecting seat, and the limit block is fixedly connected to the connecting seat by bolts.

[0015] The connection seat is used to install the limit block. After the push card board is reset, the limit block can limit its position to ensure the pushing distance of the push card board. The limit block is fixed to the connection seat by bolts. The distance of the limit block on the connection seat is adjustable, so that the position of the push card board on the upper end face of the card holder can be adjusted, so that the push card board can push various types of mahjong tiles.

[0016] Preferably, both ends of the driving part are connected to the card holder through springs, grooves are provided on both sides of the protrusion on the driving part, and the grooves and the protrusions are connected by an arc transition. When the card pushing plate pushes the card, the pressure rod moves into the groove.

[0017] The spring can make the card pushing bracket reset in time. When the pressure rod moves to the driving part, the grooves on both sides of the protrusion can provide a buffering effect to the pressure rod, thereby ensuring the stability of pushing and resetting the card pushing plate.

[0018] Preferably, it also includes a lifting board assembly for lifting mahjong tiles to the table top, the lifting board assembly includes a lifting board and a guide plate, the guide plate is vertically fixed on the lower end surface of the lifting board, a track groove and a second notch are provided at the lower end of the guide plate, the second notch is connected to the track groove, the track groove is an elongated track groove, the track groove runs through the front and rear side surfaces of the guide plate, the inner wall of the upper end surface of the track groove is horizontally arranged, a push rod is installed on the outer end surface of the rocker arm, the push rod extends into the track groove through the second notch, the push rod moves in the track groove and drives the guide plate to rise and fall, and the guide plate is pressed on the inner end portion of the push rod.

[0019] The card lifting board assembly is used to receive the mahjong tiles pushed by the card pushing board and lift the mahjong tiles onto the table. The rocker arm rotates and drives the push rod to rotate, and the push rod moves in the track groove and drives the card lifting board assembly to rise and fall.

[0020] Preferably, a mahjong card conveying device is also included, which includes a conveying frame, on which a support block is fixed. When the card lifting plate is lifted onto the table, the outer end of the push rod is supported on the support block.

[0021] When the card lifting board assembly lifts the mahjong tiles onto the table, the push rod rotates to the highest point. At this time, the card lifting board assembly presses the gravity of the mahjong tiles on the inner end of the push rod, and the support block can support the outer end of the push rod to prevent the push rod from being deformed by pressure.

[0022] A mahjong machine also includes a card pushing device.

[0023] The present invention has significant technical effects due to the adoption of the above technical solution:

[0024] The card pushing and lifting device realizes the movement of the card pushing plate through the principle of a seesaw, eliminates the driven gear and cam structure in the traditional card pushing plate, simplifies the structure of the card pushing and lifting device, and reduces the manufacturing cost. The card pushing bracket of the device is a seesaw, and the card pushing bracket is hinged on the card bearing seat. One end of the card pushing bracket is fixed on the card pushing plate, and the other end is installed under the rocker arm through a spring.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 The present invention is further described in detail with examples.

[0032] Example 1

[0033] A card pushing device includes a card holder 10, which is placed on the bottom plate of a mahjong machine. A motor 11 and a card pushing plate 12 are installed on one side of the card holder 10, and a rocker arm 22 for lifting a card lifting plate assembly 18 to a tabletop is installed on the other side of the card holder 10. The output shaft of the motor 11 passes through the card holder 10 and is connected to the rocker arm 22, and the motor 11 can drive the rocker arm 22 to rotate. The card pushing device also includes a card pushing bracket 13 and a spring 14, the lower end of the card pushing bracket 13 is hinged on the card holder 10, one end of the card pushing bracket 13 is fixed on the card pushing plate 12 by bolts, and the other end thereof passes under the card holder 10 and is connected to the other side of the card holder 10 by the spring 14. The card pushing bracket 13 on the same side as the rocker arm 22 is set as the driving part 131. The driving part 131 is provided with a protruding block 1311 protruding upwards. The end face of the protruding block 1311 is an arc-shaped track surface 1312. The inner end face of the rocker arm 22 is installed with a pressing rod 15. When the card pushing plate 12 pushes cards, the rocker arm 22 rotates and drives the pressing rod 15 to move to the driving part 131. The pressing rod 15 presses the driving part 131 along the arc-shaped track surface, and the other end of the card pushing bracket 13 tilts upward and pushes the card pushing plate 12 to move. When the pressing rod 15 moves to the highest point of the arc-shaped track surface 1312, it means that the card pushing plate 12 has been pushed to the limit position. At this time, the pressing rod 15 extends the arc-shaped track surface 1312 to move, and the card pushing plate 12 will be linearly reset to the original position. The card pushing bracket 13 of the device is a seesaw, which is hinged on the card bearing seat 10, one end of the card pushing bracket 13 is fixed on the card pushing plate 12, and the other end is installed under the rocker arm 22 through the spring 14. When working, the rocker arm 22 drives the card lifting plate assembly 18 to descend, and at the same time, the pressure rod 15 on it will press down the driving part 131, and the card pushing bracket 13 at the end of the card pushing plate 12 will be pressed up, thereby pushing the card pushing plate 12. When the pressure rod 15 is pressed down, it moves along the arc track surface 1312 of the protrusion 1311, ensuring that the card pushing plate 12 linearly pushes the mahjong tiles, so that the mahjong tiles can be smoothly pushed to the card lifting plate assembly 18.

[0034] The card pushing bracket 13 on the same side as the card pushing plate 12 is set as the card pushing part 132, and the card pushing part 132 is fixedly connected to the driving part 131 through the connecting part 133. In this embodiment, the card pushing bracket 13 is an integrated bracket, the connecting part 133 is a connecting plate, and the driving part 131 is a connecting plate bent toward the upper end surface of the card receiving seat 10 to form a bent plate. The lower end of the card receiving seat 10 is provided with a first notch 101 for the card pushing bracket 13 to pass through, the first notch 101 runs through the front and rear end surfaces of the card receiving seat 10, and the first notch 101 is a door frame-shaped notch, and the connecting part 133 is installed in the first notch 101, and its two ends are hinged on the wall of the first notch 101. Connecting blocks are fixed at both ends of the connecting part 133, and the connecting blocks are hinged on the wall of the first notch 101 through a pin shaft. The card pushing part 132 is a card pushing rod, and the two ends of the connecting part 133 are fixed with card pushing rods. A connecting rod 134 is fixed between the two card pushing rods. The connecting rod 134 can increase the stability of the ends of the card pushing rods, so that the two card pushing rods push the card pushing plate 12 at the same time. The two card pushing rods, the connecting rod 134 and the connecting part 133 form a circle, and the motor 11 is surrounded in this circle. The middle part of the card pushing rod is an arc rod, and the middle part is arched away from the card receiving seat 10. Since the card pushing bracket 13 is a seesaw structure principle, the moving track of the end of the card pushing rod is an arc, and the arched card pushing rod can ensure that the card pushing plate 12 does not separate from the mahjong tiles when pushing cards.

[0035] A connecting seat 16 protruding horizontally outward is installed on the card holding seat 10 on the same side as the card pushing plate 12. The connecting seat can be integrally formed on the card holding seat 10. In other embodiments, the connecting seat 16 can also be bolted to the card holding seat 10. A limit block 17 for limiting the resetting of the card pushing plate 12 is installed on the connecting seat 16. The upper end of the limit block 17 extends vertically upward to the rear of the card pushing plate 12, and the lower end of the limit block 17 is fixedly connected to the connecting seat 16 by bolts.

[0036] Both ends of the driving part 131 are connected to the card holder 10 through the spring 14, so as to ensure that the two ends of the driving part 131 are evenly stressed. When the card pushing plate 12 pushes the mahjong tiles onto the card raising plate assembly 18, the spring 14 can reset the card pushing plate 12 in time. Both sides of the protrusion 1311 on the driving part 131 are provided with grooves 1313, and the connection between the grooves 1313 and the protrusion 1311 is connected by an arc transition. When the card pushing plate 12 pushes the tiles, the pressure rod 15 moves into the grooves 1313. When the pressure rod 15 moves onto the driving part 131, the grooves 1313 on both sides of the protrusion 1311 can provide a buffering effect to the pressure rod 15, so as to ensure the stability of the card pushing and resetting of the card pushing plate 12.

[0037] Example 2

[0038] The features of the second embodiment are basically the same as those of the first embodiment, except that the card-lifting device further includes a card-lifting plate assembly 18 for lifting the mahjong cards to the table. The card-lifting plate assembly 18 includes a card-lifting plate 181, a guide plate 182 and a lifting shaft 183. The guide plate 182 is vertically fixed on the lower end surface of the card-lifting plate 181. The lifting shaft 183 is arranged on both sides of the guide plate 182 and is vertically fixedly connected to the card-lifting plate 181. Two guide seats 102 are fixed on the end surface of the card-receiving seat 10 on the same side as the rocker arm 22. The guide seats 102 are arranged at both ends of the card-receiving seat 10. The lifting shaft 183 is lifted and lowered on the guide seats 102, thereby ensuring the stability of the lifting of the card-lifting plate 181. A track groove 1821 and a second notch 1822 are arranged at the lower end of the guide plate 182. The second notch 1822 is connected to the track groove 1821, and the second notch 1822 passes through the front and rear end surfaces of the guide plate 182. The track groove 1821 is a long strip track groove, which passes through the front and rear sides of the guide plate 182. The inner wall of the upper end surface 18211 of the track groove 1821 is horizontally arranged. The outer end surface of the rocker arm 22 is installed with a push rod 19. When the card lifting plate assembly 18 is installed on the card receiving seat 10, the push rod 19 extends into the track groove 1821 through the second notch 1822. The push rod 19 moves in the track groove 1821 and drives the guide plate 182 to rise and fall. The guide plate 182 is pressed on the inner end of the push rod 19. When the card pushing plate 12 pushes cards, the push rod 19 on the rocker arm 22 moves in the second notch 1822, but does not move out of the second notch 1822. At this time, the push rod 19 does not contact the upper end surface 18211 of the track groove 1821.

[0039] The card lifting device also includes a mahjong card conveying device, which includes a conveying frame 20, on which a support block 21 is fixed. When the card lifting board 181 is lifted onto the table, the outer end of the push rod 19 is supported on the support block 21, and the upper end of the support block 21 is an arc-shaped surface, which facilitates the push rod 19 to move onto the support block 21. When the card lifting board assembly 18 lifts the mahjong cards onto the table, the push rod 19 rotates to the highest point. At this time, the card lifting board assembly 18 presses the gravity of the mahjong cards on the inner end of the push rod 19, and the support block 21 can support the outer end of the push rod 19, thereby preventing the push rod 19 from being compressed and deformed.
