Referring to fig. 1, an embodiment of the present utility model provides a mahjong machine, which uses an improved rotary lifting device, and changes the original simple lifting mode into a rotary lifting mode.

Referring to fig. 1 and 3, in an alternative embodiment, an improved rotary lift device includes a rotary body 1, a lift mechanism 2 disposed within the rotary body 1, and a card receiving plate 5 disposed below the rotary body 1. The card path 11 which is communicated in the vertical direction is further arranged in the rotary body 1, and the lifting mechanism 2 moves up and down on the card path 11. The lifting mechanism 2 is controlled by a driving mechanism 3, the driving mechanism 3 comprises a first gear 31 and a second gear 32 meshed with the first gear 31, and the second gear 32 drives the card receiving plate 5 to rotate so that the highest position of the card receiving plate is in a changing state.

Referring to fig. 2, in an alternative embodiment, the driving mechanism 3 further includes a third gear 33 meshed with the second gear 32, the third gear 33 is disposed below the second gear 32, and a motor is connected to the third gear 33. The three gears have the same size, so that the rotation angle can be conveniently controlled. The third gear 33 is also provided for placing the motor, and the first gear 31 is positioned without sufficient space.

Referring to fig. 2, in an alternative embodiment, the lifting mechanism 2 includes a lifting plate 22 driven by the driving mechanism 3, and a rocker arm 21 is disposed on the lifting plate 22, and the rocker arm 21 is disposed on the first gear 31.

Referring to fig. 2, in an alternative embodiment, a track groove 221 is formed on a side of the lifting plate 22 near the swing arm 21, and a slider 211 moving on the track groove 221 is formed on the swing arm 21. The slider 211 may be a bearing with a small friction.

Referring to fig. 1 and 5, in an alternative embodiment, a non-return mechanism 4 is provided on a side of the rotating body 1 adjacent to the first gear 31.

Referring to fig. 5, in an alternative embodiment, the backstop mechanism 4 includes two sets of clamping blocks 41 symmetrically disposed on the rotating body 1 and a backstop plate 42 rotatably disposed.

Referring to fig. 5, in an alternative embodiment, the non-return plate 42 is symmetrically provided with arc-shaped protrusions 421, the clamping blocks 41 are L-shaped, and each group of clamping blocks 41 is symmetrical left and right. When the rocker arm 21 rotates to one side, the check plate 42 on one side in the rotation direction is abutted against the clamping block 41 to prevent the rotation body 1 from rotating in the opposite direction of the rotation of the rocker arm 21.

Referring to fig. 1 and 2, in an alternative embodiment, a mounting plate 6 is further included for mounting the non-return plate 42, the first gear 31 and the second gear 32.

The specific working process comprises the following steps:

initially, the mahjong machine is in the state of fig. 1. At this time, the lifting plate 22 is at the highest position, and the mahjong is just conveyed to the tabletop for the person playing the mahjong to use. At the same time, the mahjong pieces in the mahjong table are shuffled and then enter the tile path shown in fig. 3, are stacked on the tile receiving plate 5 one by one, and the face of the mahjong with flowers faces upwards, which is different from the prior art that the flowers cannot be seen after being stacked. The first rocker arm 21 at this time is vertically upward, in the 12-point direction, as shown in fig. 2. At this time, the card receiving plate 5 is positioned at the highest position to facilitate card stacking. The side surface of the card receiving plate 5 is oval, and the highest position of the card receiving plate 5 can also rotate in the rotation process of the second gear 32, so that the card stacking is convenient. Although the width of the tile receiving board 5 is smaller than the width of the tile path 11, the width of the mahjong is not quite different from the width of the tile path 11, so that the mahjong cannot fall out.

When the next mahjong is completed, the motor of the driving mechanism is rotated clockwise (from the point of view of fig. 2, the following clockwise and counterclockwise directions) to move the slider 211 to the right side of the track groove 221, and the swing arm 21 is approximately in the direction of 1 point, so that the lifting plate 22 is lowered. At the same time, the card receiving plate 5 is driven by the second gear 32 to slowly descend, and the rotating body 1 is less stressed and cannot rotate when the card receiving plate is in the direction from 12 o 'clock to one o' clock. The check plate 42 abuts against the block 41 on the upper right side to prevent the rotary body 1 from rotating counterclockwise.

The motor of the driving mechanism 3 continuously rotates clockwise to drive the rotary body 1 to turn over 180 degrees, the mahjong pieces turn over 180 degrees, and the mahjong pieces face downwards. In order to prevent mahjong tiles from leaking from the bottom of the tile channel 11, an arc-shaped baffle plate is arranged around the rotary body 1, and the mahjong tiles slowly rotate and rise along the arc-shaped baffle plate. The rocker arm 21 now assumes a substantially seven-point orientation.

The first rocker arm 21 rotates counterclockwise, moving from the seven o 'clock direction to the six o' clock direction, and the lifter plate 2 descends. The first rocker arm 21 continues to rotate anticlockwise to drive the lifting plate 2 to lift, and the first rocker arm 211 is vertically upwards in the direction of 12 o' clock rotation of the first rocker arm 21, namely to the middle position of the track groove 221, so that the mahjong pieces are moved above the table top. The mahjong table begins to be pre-shuffled again. In order to prevent the rotation of the rotary body 1 therein, the upper right side clamping block 41 is abutted by the check plate 42, and in order to keep the upper right side clamping block 41 and the check plate 42 clamped with each other, a magnet is added to the clamping block 41 which can move to the upper right side, or a torsion spring is used. The 4 clamping blocks 41 are selected, so that the motor can conveniently rotate in different directions at the later stage, a new clamping block is not required to be selected, and the motor is installed in advance.

The steps are reciprocated, so that the mahjong machine is operated.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, or alternatives falling within the spirit and principles of the utility model.
