Abstract

The utility model relates to a mahjong pushing and lifting linkage structure of a mahjong machine. The connecting rod solves the technical problems that after long-distance transmission and long-time use of an existing connecting rod, dislocation or abrasion can happen to a linkage connecting part and the like. Comprising a tile pushing frame movably arranged in a tile pushing channel and a tile lifting plate vertically movably arranged in a tile lifting groove, a linkage groove is formed in one side of the tile lifting groove, a linkage plate is movably arranged in the linkage groove, and a tile lifting plate lifting structure capable of lifting the tile lifting plate upwards when the linkage plate moves in the direction away from the tile pushing channel is arranged between the linkage plate and the linkage groove.

The silent mahjong tile pushing device has the advantages that by means of the structural design of the silent reset column and the silent inclined sliding block, when the linkage plate is reset through the linkage plate reset spring, the speed of resetting of the linkage plate can be effectively reduced through the silent reset column and the silent inclined sliding block, and therefore noise or damage caused by collision between the linkage plate and the mahjong tile pushing frame is avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machine equipment, and particularly relates to a mahjong machine card pushing and raising linkage structure. Background Art

[0002] An automatic mahjong machine is provided with a card pushing mechanism and a card lifting mechanism. The card pushing mechanism pushes the mahjong tiles onto the card lifting mechanism, which then lifts the mahjong tiles onto the table of the mahjong machine. The two mechanisms operate asynchronously, so two motors are required to drive the card pushing mechanism and the card lifting mechanism respectively. In order to reduce production costs, an oblique card loading mahjong machine with a linked card pushing and lifting mechanism has appeared on the market. The machine uses the power of one motor to transmit the card pushing and lifting actions through a connecting rod. However, due to the long transmission distance of the connecting rod and the dislocation or wear of the connecting parts after long-term use, the performance and stability of the mahjong machine are reduced. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems and provide a mahjong machine card pushing and raising linkage structure.

[0004] To achieve the above-mentioned object, the present invention adopts the following technical solutions: a mahjong machine card pushing and raising linkage structure, comprising a card pushing rack movably arranged in a card pushing channel and a card raising plate movably arranged in a card raising slot, one side of the card raising slot being connected to the card pushing channel, a linkage plate movably arranged in the linkage slot so as to be pushed by the card pushing rack and move in a direction away from the card pushing channel, a card raising plate lifting structure being arranged between the linkage plate and the linkage slot so as to lift the card raising plate upward when the linkage plate moves in a direction away from the card pushing channel, and the linkage plate being further connected to a silent elastic reset structure so as to reset the linkage plate in the direction of the card pushing channel when the card pushing rack is separated from the linkage plate. The card pushing rack and the silent elastic reset structure drive the linkage plate to move in the linkage slot, and the linkage plate is connected to the card raising plate via the card raising plate lifting structure, so that the movement of the linkage plate drives the lifting plate to rise or fall.

[0005] In the aforementioned mahjong machine's tile-pushing and tile-raising linkage structure, the linkage slot and tile-raising slot are arranged in the same direction, and one end of the linkage plate extends into or to one side of the tile-pushing channel. The design position of the linkage slot and tile-raising plate reduces the transmission distance between the linkage plate and tile-raising plate, thereby improving transmission stability.

[0006] In the above-mentioned linkage structure for pushing and raising cards of a mahjong machine, a linkage shell is provided in the linkage slot, the linkage shell has a shell side portion close to the raising plate, and the linkage shell is open at one end close to the pushing channel.

[0007] In the aforementioned mahjong machine's tile-pushing and tile-raising linkage structure, the tile-raising plate lifting mechanism includes a tile-raising seat and a tile-raising swing arm, located at the lower middle portion of the tile-raising plate. A curved tile-raising track is provided on one side of the tile-raising seat. One end of the tile-raising swing arm includes a short tile-raising shaft that slides within the track. A tile-raising plate lifting assembly is provided between the linkage housing and the tile-raising plate. The swing arm is connected to the tile-raising track of the seat via the short tile-raising shaft. When the swing arm swings, the tile-raising plate rises or falls accordingly.

[0008] In the aforementioned mahjong machine's tile-pushing and tile-raising linkage structure, the tile-raising plate lifting assembly includes a swing arm mounting seat disposed on one side of the housing and extending into the tile-raising slot. A swing arm rotating shaft is disposed within the swing arm mounting seat. One end of the swing arm rotating shaft is disposed within the tile-raising slot and connected to the end of the tile-raising swing arm. The linkage plate is linked to the swing arm rotating shaft via a rack-and-pinion linkage structure. The swing arm mounting seat secures the swing arm rotating shaft, which is connected to the tile-raising swing arm, thereby transmitting power.

[0009] In the above-mentioned mahjong machine card pushing and raising linkage structure, the gear rack linkage structure includes a linkage rack arranged at the lower end of the linkage plate and extending axially along the linkage plate, the swing arm shaft is away from one end of the card raising swing arm and penetrates into the linkage shell and is provided with a linkage gear, and the linkage rack and the linkage gear are meshed.

[0010] In the above-mentioned mahjong machine card pushing and raising linkage structure, the silent elastic reset structure includes a silent reset component arranged between the card pushing frame and the linkage plate and an elastic reset component arranged between the linkage shell and the linkage plate.

[0011] In the aforementioned mahjong machine card pushing and raising linkage structure, the silent reset assembly includes a silent reset post disposed on the linkage plate's end near the card pushing frame and away from the raising plate. The push frame has a silent, angled slider on its side, and the slider has a straight portion on its side away from the push frame, which abuts against the silent reset post. The abutment of the silent reset post and the silent, angled slider slows the reset of the linkage plate, thereby reducing the impact force of the reset and preventing noise or damage to components.

[0012] In the aforementioned linkage structure for pushing and raising cards in a mahjong machine, the elastic reset assembly includes a plurality of guide slots extending axially along a linkage plate, a plurality of guide posts disposed within a linkage housing corresponding one to each of the guide slots, the guide posts being inserted into the guide slots and slidably connected thereto, the linkage plate slidably engaging with guide ribs within the linkage housing and / or the side of the housing, and a linkage plate reset spring disposed between one of the guide posts and the end of the linkage plate away from the card pusher. The linkage plate is reset by the reset spring, and the guide posts and guide slots prevent the linkage plate from misaligning during movement.

[0013] In the above-mentioned mahjong machine card pushing and raising linkage structure, the side of the shell near one end of the card pushing channel is provided with a shell fixing part located in the card raising slot, and the card raising slot is provided with a shell connecting column corresponding to the shell fixing part, and one end of the card raising plate is hinged to the end of the card raising slot away from the shell connecting column.

[0014] Compared with the existing technology, the advantages of this utility model are:

[0015] 1. The device utilizes the structural design of silent reset column and silent oblique slider. When the linkage plate is reset by the linkage plate reset spring, the silent reset column and silent oblique slider can effectively reduce the speed of the linkage plate when it is reset, thereby avoiding the linkage plate and the card pusher frame from colliding and causing noise or damage.

[0016] 2. The device pushes the linkage plate through the card pushing rack, and the linkage plate controls the lifting function of the card lifting plate through the card lifting plate lifting structure. The structural design of the channel linkage plate and the short-distance transmission improve the stability of the card lifting. BRIEF DESCRIPTION OF THE DRAWINGS

One side of the card lifting slot 2 is provided with a linkage slot 3 connected to the card pushing channel 1. A linkage plate 31 is movably provided in the linkage slot 3, which can move toward a direction away from the card pushing channel 1 under the push of the card pushing rack 11 when the card pushing rack 11 moves in the card pushing channel 1. A lifting plate lifting structure 4 is provided between the linkage plate 31 and the linkage slot 3, which can lift the card lifting plate 21 upward when the linkage plate 31 moves toward the direction away from the card pushing channel 1, and the linkage plate 31 is also connected to a silent elastic reset structure 5 which can reset the linkage plate 31 toward the card pushing channel 1 when the card pushing rack 11 is separated from the linkage plate 31. The card pushing rack 11 and the silent elastic reset structure 5 drive the linkage plate 31 to move in the linkage slot 3. At the same time, the linkage plate 31 is connected to the lifting plate 21 through the lifting plate lifting structure 4. The movement of the linkage plate 31 drives the lifting plate 21 to rise or fall.

[0026] like Figure 3 As shown, the linkage slot 3 and the card-raising slot 2 are arranged in the same direction, and one end of the linkage plate 31 extends into the card-pushing channel 1 or is located on one side of the card-pushing channel 1. The design position of the linkage slot 3 and the card-raising plate 2 can reduce the transmission distance between the linkage plate 31 and the card-raising plate 21, thereby improving the transmission stability.

[0027] like Figure 4 As shown, a linkage housing 32 is provided in the linkage slot 3 , and the linkage housing 32 has a housing side portion 33 on the side close to the card raising plate 21 , and the linkage housing 32 is open at one end close to the card pushing channel 1 .

[0028] like Figure 5As shown, the lifting plate lifting structure 4 includes a lifting seat 41 and a lifting swing arm 42 arranged at the lower end of the middle part of the lifting plate 21. A curved lifting track 43 is provided on one side of the lifting seat 41. One end of the lifting swing arm 42 has a lifting short shaft 44 that slides within the lifting track 43. A lifting plate lifting assembly 45 is provided between the linkage housing 32 and the lifting plate 21. The lifting swing arm 42 is connected to the lifting track 43 of the lifting seat 41 via the lifting short shaft 44. When the lifting swing arm 42 swings, the lifting plate 21 begins to rise or fall following the swing.

[0029] The card-lifting plate lifting assembly 45 includes a swing arm mounting base 46 disposed on one side of the housing side 33 and extending into the card-lifting slot 2. A swing arm rotating shaft 47 is disposed within the swing arm mounting base 46. One end of the swing arm rotating shaft 47 is disposed within the card-lifting slot 2 and connected to the end of the card-lifting swing arm 42. The linkage plate 31 is linked to the swing arm rotating shaft 47 via a gear rack linkage structure 6. The swing arm mounting base 46 is used to fix the swing arm rotating shaft 47. The swing arm rotating shaft 47 is connected to the card-lifting swing arm 42, and the swing arm rotating shaft 47 plays the role of transmitting power.

[0030] Specifically, the rack-and-pinion linkage structure 6 includes a linkage rack 61 disposed at the lower end of the linkage plate 31 and extending axially along the linkage plate 31. The end of the swing arm shaft 47, which is away from the lifting swing arm 42, penetrates into the linkage housing 32 and is provided with a linkage gear 62. The linkage rack 61 and the linkage gear 62 are meshed. This simple structure is conducive to operational stability.

[0031] Combine Figure 1 、 Figure 2 and Figure 6 As shown, the silent elastic reset structure 5 includes a silent reset component 51 arranged between the card pushing frame 11 and the linkage plate 31 and an elastic reset component 52 arranged between the linkage housing 32 and the linkage plate 31 .

[0032] The silent reset assembly 51 includes a silent reset post 53 disposed on one end of the linkage plate 31 close to the card pusher 11 and away from the card lifting plate 21. A silent inclined slider 54 is provided on one side of the card pusher 11. The silent inclined slider 54 has a straight portion 55 on the side away from the card pusher 11, and the straight portion 55 abuts against the silent reset post 53. The abutment between the silent reset post 53 and the silent inclined slider 54 can slow the reset of the linkage plate 31, thereby reducing the reset impact force of the linkage plate 31 and avoiding noise or damage to parts.

[0033] Specifically, the elastic reset assembly 52 includes a plurality of guide grooves 56 extending axially along the linkage plate 31, a plurality of guide posts 57 corresponding one to one with the guide grooves 56 are provided in the linkage housing 32, the guide posts 57 are inserted into the guide grooves 56 and the two are slidably connected, the linkage plate 31 and the guide ribs 58 and / or the housing side 33 in the linkage housing 32 are slidably engaged, and a linkage plate reset spring 59 is provided between one of the guide posts 57 and the end of the linkage plate 31 away from the card pusher 11. The linkage plate 31 is reset by the linkage plate reset spring 59, and the guide posts 57 and the guide grooves 56 can prevent the linkage plate 31 from being misaligned when moving.

[0034] Combine Figure 3 and Figure 4 As shown, a shell fixing portion 34 located in the card raising slot 2 is provided at one end of the shell side 33 close to the card pushing channel 1, and a shell connecting column 35 corresponding to the shell fixing portion 34 is provided in the card raising slot 2, and one end of the card raising plate 21 is hinged to the end of the card raising slot 2 away from the shell connecting column 35.

[0035] The principle of this embodiment is:

[0036] When the card pushing rack 11 abuts against the linkage plate 31, the linkage plate 31 begins to move in the direction away from the card pushing channel 1, and the movable plate reset spring 59 begins to tighten. When the linkage plate 31 loses its abutment against the card pushing rack 11, the silent reset column 53 begins to abut against the silent inclined slider 54, and the movable plate reset spring 59 resets, and the linkage plate 31 begins to move toward the card pushing channel 1. The linkage rack 61 on the linkage plate 31 is connected to the linkage gear 62 on the swing arm shaft 47. At the same time, the swing arm rotation 47 is connected to the card lifting seat 41 of the card lifting plate 21 through the card lifting swing arm 42. When the linkage plate 31 starts to move, the card lifting swing arm 42 swings, thereby driving the card lifting plate 21 to rise or fall.
