When the transmission gear ring is arranged as a whole circle of transmission gear, the production cost of the transmission gear ring is higher due to the larger diameter of the transmission gear ring, however, in the application of the mahjong machine, the transmission gear ring does not do circular motion, but swings in a small range, and the whole circle of transmission gear is extremely low in utilization rate although the cost is high.
Therefore, in the present embodiment, only one section of the rack 41 for meshing with the driving gear 32 is provided to meet the requirement of driving the card lifting plate to lift.
Preferably, in the present embodiment, the four-stage rack 41 is provided, because the driving mechanism is only provided with one group, and after being mounted at a certain position on the frame, the mounting manner of the transmission gear ring is more, the requirement of position accuracy is lower, and the mounting efficiency can be improved. In addition, after the section of rack 41 is worn, the installation position of the transmission gear ring can be changed, so that the unworn rack is meshed with the driving gear, and the service life is prolonged.
In this embodiment, although only one set of driving mechanism and driving gear ring is provided, due to the four card lifting boards, the driving assembly 50 is still provided with four sets and corresponds to the four card lifting boards 20 one by one, the input end of the driving assembly is connected with the first driving post 42 in an adapting manner, and the output end of the driving assembly is connected with the driving groove 23 of the card lifting board 20 in an adapting manner.

In this embodiment, the bottom of the slider is provided with a first sliding groove 521, preferably, the first sliding groove 521 is a waist-shaped groove, and the first transmission post 42 is located in the first sliding groove 521 and can move in the longitudinal direction in the first sliding groove. Preferably, rolling structures, such as bearings, rollers, etc., may be provided on the first drive post 42 with less friction for rolling engagement.
In this embodiment, a second sliding groove 522 is further disposed on one side of the slider 52, and is adapted to be connected to the link assembly 51, and preferably, the second sliding groove 522 is a waist-shaped groove.

Preferably, the third transmission post 515 may be provided with rolling structures, such as bearings, rollers, etc., with less friction for rolling engagement.
In the mahjong machine of this embodiment, the driving gear is driven to drive the transmission gear ring to rotate by starting the motor 30 to rotate forward or reversely, the first transmission column on the transmission gear ring drives the sliding block to slide, the sliding block drives the connecting rod assembly to swing around the rotating connecting rod, and then the tile lifting plate is driven to swing around the hinge part by the cooperation of the third transmission column and the transmission groove, so that the tile lifting plate is lifted.
In summary, the foregoing description is only of the preferred embodiments of the utility model, and is not intended to limit the utility model to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
