Description

Technical Field

[0001] The invention belongs to the technical field of mahjong tiles for automatic mahjong machines, and particularly relates to low-noise mahjong tiles which can effectively reduce noise in the process of shuffling and arranging tiles, have low resistance to stacking tiles, and do not affect the feel of players touching the tiles. Background Art

[0002] The existing fully automatic mahjong machines are all equipped with two sets of mahjong tiles, namely: one set of mahjong tiles is used for the game on the table; the other set of mahjong tiles is shuffled in order by the shuffling mechanism inside the mahjong machine, and then stacked by the stacking mechanism, and finally enters the lifting mechanism for standby. At present, the mahjong tiles used in automatic mahjong machines are all die-casted with melamine (tripolycyanamide) materials, and the magnets used for automatic flipping of mahjong tiles are pressed in them, and then polished at the corners. Although melamine mahjong tiles have high strength and hardness, smooth feel and good wear resistance, due to the hardness of melamine, the mahjong tiles will generate a lot of noise when they are shuffled, stirred, sorted and stacked in the mahjong machine, affecting the normal communication of players during the game; especially at night, the loud shuffling sound is very disturbing, and the noise pollution is serious.

[0003] In addition, some existing silent mahjong tiles are all in a simple structure of fully surrounded by soft materials. Although the purpose of noise reduction is achieved, players generally complain that the hand feeling of touching the tiles is not good, which seriously affects the game experience. Moreover, such fully surrounded soft mahjong tiles often fail to stack properly during stacking in a fully automatic mahjong machine due to the large resistance between the two layers of mahjong tiles. Therefore, it has not been widely used. Therefore, it is necessary to improve the mahjong tiles used in the prior art automatic mahjong machine. Summary of the invention

[0004] The present invention aims at the above problems and provides a low-noise mahjong tile which can effectively reduce the noise in the process of shuffling and arranging cards, has small resistance to stacking cards, and does not affect the player's feeling of touching the cards.

DETAILED DESCRIPTION

[0024] according to Figures 1 to 11 The specific structure of the present invention is described in detail. The low-noise mahjong tiles include a soft tile body 1, which is composed of a tile body 9 made of a soft material such as latex or polyurethane. A through cavity 10 is provided in the middle of the tile body 9, which runs through the back and back of the tile assembly 3 and the tile face assembly 2. The outer periphery of the through cavity opening on the side of the back 5 of the soft tile body 1 facing the back 3 of the tile assembly 3 is provided with an annular back 5 card clamping groove 12; the outer periphery of the through cavity opening on the side of the soft tile body 1 facing the tile face 13 of the tile face assembly 2 is provided with an annular tile face clamping convex edge 11.

[0025] At the openings on both sides of the through cavity 10 of the soft card body 1, a card back assembly 3 and a card face assembly 2 are respectively arranged. The card back assembly 3 includes a card body back 5 made of hard materials such as melamine or PC plastic, and a card back connection plug block 6 for plugging into the through cavity 10 of the soft card body 1 is arranged on the front side of the card body back 5; and a card face connection slot 7 with an opening facing the card face assembly 2 and for plugging into the card face connection plug block 14 is arranged on the card back connection plug block 6 of the card back assembly 3. The card back 5 of the card back assembly 3, which faces the periphery of the side of the soft card body 1, is provided with an annular card back clamping convex edge 8 for matching and connecting with the card back clamping groove 12 of the soft card body 1. Therefore, the card back clamping convex edge 8 of the card back assembly 3 and the card back clamping groove 12 of the soft card body 1 are used to improve the connection positioning accuracy between the card back assembly 3 and the soft card body 1, and increase the firmness of the connection.

[0026] The card face assembly 2 includes a card body face 13 made of hard materials such as melamine or PC plastic, and the front side of the card body face 13 is engraved with mahjong tile graphics; the back side of the card body face 13 is provided with a card face connection plug-in block 14 for plugging into the card face connection slot 7 of the card back assembly 3. The card body face 13 of the card face assembly 2, which faces the side of the soft card body 1, is provided with an annular card face clamping groove 16 for matching and connecting with the card face clamping convex edge 11 of the soft card body 1. Furthermore, through the matching clamping of the card face clamping groove 16 of the card face assembly 2 and the card face clamping convex edge 11 of the soft card body 1, the positioning accuracy and firmness of the connection between the card face assembly 2 and the soft card body 1 are effectively improved. At the same time, a magnet receiving groove 15 with an opening toward the back face assembly 3 is provided on the card face assembly 2; a face magnet 4 made of a neodymium iron boron material for automatically turning over the mahjong tiles is fixedly provided in the magnet receiving groove 15 on one side close to the card body face 13. In addition, the space on the side where the face magnet 4 is not arranged in the magnet receiving groove 15 can be filled with a lightweight filler; thereby effectively preventing the face magnet 4 from moving, ensuring that the center of gravity of the mahjong tiles is biased toward the side of the card body face 13, so as to facilitate the automatic turning over of the low-noise mahjong tiles during the stacking process of the automatic mahjong machine stacking mechanism.

[0027] The card back connecting plug block 6 of the card back assembly 3 extends from the back of the soft card body 1 into the through cavity 10; the card face connecting plug block 14 of the card face assembly 2 extends into the through cavity 10 via the face of the soft card body 1, and is plugged into the card face connecting slot 7 of the card back connecting plug block 6 extending into the through cavity 10 of the soft card body 1 from the other side. At the same time, the card body face 13 of the whole block structure on the card face assembly 2 is located outside the through cavity opening of the soft card body 1 face; the card body back 5 on the card back assembly 3 is located in the through cavity opening of the back of the soft card body 1, and the outer surface of the card body back 5 is flush with the outer wall of the back of the soft card body 1. Therefore, the card face assembly 2 and the card back assembly 3 arranged on both sides of the soft card body 1 are plugged into each other in the through cavity 10, so that the three are combined into a whole. The soft card body 1 of low-noise mahjong tiles is used to effectively reduce the noise during shuffling and sorting, and the card body surface 13 of the card face assembly 2 is exposed outside the soft card body 1 to ensure the player's hand feeling when touching the cards.

[0028] In order to increase the reliability of the mahjong tile combination connection, the inner walls of the through cavity 10 of the soft card body 1 are all designed as inclined surfaces, and the inclined inner wall of the through cavity 10 of the soft card body 1 has an inclination angle α from the side of the card back assembly 3 to the side of the card face assembly 2 between 1 degree and 3 degrees, preferably 1.5 degrees; so as to further improve the connection tightness between the soft card body 1 and the hard card face assembly 2 and the card back assembly 3 on both sides. According to the specific connection and use needs, the outer wall of the card back connection plug 6 of the card back assembly 3, the inner wall of the card face connection slot 7, and the outer wall of the card face connection plug 14 of the card face assembly 2, and the inner wall of the magnet receiving groove 15 can all adopt the structure of inclined surfaces.

[0029] In the process of random shuffling of the low-noise mahjong tiles by the shuffling mechanism inside the existing fully automatic mahjong machine, except for the card body face 13 exposed outside the soft card body 1, the rest of the mahjong tiles are wrapped by the soft card body 1, and the hard card body face 13 of two mahjong tiles are difficult to collide due to the mutual repulsion between the face magnets 4 respectively arranged inside them; therefore, the noise in the shuffling and card arrangement process of the automatic mahjong machine is effectively reduced. At the same time, the whole block structure of the card body face 13 exposed outside the soft card body 1 ensures the feel of the player when touching the cards. It can be understood that after removing the face magnets 4 in the card face assembly 2 of the low-noise mahjong tiles, it can also be used as a common manually stacked mahjong tiles.
