Description

Technical Field

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

[0002] Most automatic mahjong machines on the existing market are provided with a pushing and lifting mechanism to complete actions such as card pushing and card lifting. To achieve such functions, the pushing and lifting mechanism needs to be provided with a push rod assembly, a card lifting assembly, and a driving assembly. Generally, the mahjong tiles are pushed to the card lifting assembly by the push rod and the card pushing piece in the push rod assembly and then the card lifting action is carried out. However, the connection between the push rod and the card pushing piece is poor, and the card pushing piece will rotate during the card pushing process, resulting in uneven upper and lower layers of the card strip and affecting the normal card lifting.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a simple card pushing structure for a mahjong machine [202023317032.4], which includes a rotating shaft, a card pushing swing arm, a card pushing rod, and a card pushing slider. The rotating shaft is rotatably arranged on the mahjong machine rack. One end of the card pushing swing arm is connected to the rotating shaft. A chute is arranged on the mahjong machine rack. A sliding block is arranged on the card pushing slider, and the sliding block is slidably arranged in the chute. The card pushing rod is arranged on the card pushing slider. A guiding groove is arranged on the card pushing slider. A guide rod is arranged at one end of the card pushing swing arm, and the guide rod is slidably arranged in the guiding groove. The rotation of the rotating shaft drives the card pushing swing arm to rotate, so that the guide rod slides in the guiding groove, thereby driving the card pushing slider to move along the chute, and the card pushing rod pushes the mahjong tiles from the mahjong machine rack into the card lifting mechanism.

[0004] The above solution solves the problem of uneven upper and lower layers of the existing card strip to a certain extent, but there are still many deficiencies in this solution, such as large occupied space, high precision requirements for parts, etc. Summary of the Invention
