Please refer to FIG. 1 to FIG. 3 together, which are structural schematic diagrams of the electric mahjong table-up linkage assembly of the first embodiment of the present creation, with the electric mahjong table shell hidden; the electric mahjong table-up linkage assembly Schematic diagram of the structure of the electric mahjong table; and a schematic diagram of the structure of another angle of the card-raising linkage assembly of the electric mahjong table. As shown in the figure, the card-raising linkage assembly of the electric mahjong table of the present creation includes an electric mahjong table shell 1 , a card-up track 20 , a card-up seat 2 and a support 3 . The card loading track 20 is arranged in the electric mahjong table casing 1 . The upper card seat 2 is installed at the upper card track 20 , and one end of the upper card seat 2 is rotatably connected with the electric mahjong table shell 1 . The support 3 is arranged below the upper card seat 2 . In this embodiment, the support 3 is provided at the lower middle position of the upper card seat 2 . The electric mahjong table housing 1 is also provided with a driving mechanism, and the driving mechanism includes a lifting rocker arm 7 , and the lifting rocker arm 7 is connected with the support 3 . In this way, this creation can drive the lifting swing arm 7 to swing by the driving mechanism, and the lifting swing arm 7 can drive the upper card seat 2 to rotate through the support 3, because the upper card seat 2 is not directly connected with the driving parts that can cause vibration such as the driving motor, Therefore, in the process of raising the mahjong tiles, it is not easy to shake; and, compared with the structure that directly lifts up, the space occupied by this structure is small.

Furthermore, the lifting rocker arm 7 of the present creation is provided with a rotating drum 70 that can be rotated in the electric mahjong table shell 1 . The rotating drum 70 is provided with a driving tooth 15 , and the driving mechanism also includes a The rack 10 is driven. In this way, the present invention can convert the linear motion into the rotation of the lifting and swinging arm 70 through the driving tooth 15 and the driving rack 10, which takes up less space than directly through the gear transmission.

As mentioned above, the driving rack 10 includes an upper tooth surface 11 and a lower tooth surface 12 . The driving teeth 15 are engaged with the lower tooth surface 12 , and the upper tooth surface 11 is engaged with a limit gear 13 . The limit gear 13 is rotatably connected to a limit gear fixing frame 14, and the limit gear fixing frame 14 is fixed on the electric mahjong table shell body 1. In this way, the present invention can ensure that the position of the meshing line does not change due to the change of the relative position of the lower tooth surface 12 and the driving tooth 15 by the limit gear 13 in the process of meshing and rotating with the upper tooth surface 11, so that the meshing line is always It is a fixed line tangent to the base circle and perpendicular to the upper tooth surface. At the same time, it can support the driving rack 10 downward to offset the force generated when the driving rack 10 meshes with the lower tooth surface 12 and rotates.

In addition, the driving mechanism of the present invention also includes a driving cam 5 . The drive cam 5 is used to drive the drive rack 10 . In this way, the present invention can control the action sequence of the driving rack 10 by designing the outline of the driving cam 5, thereby ensuring the stable lifting and lowering of the upper deck 2, avoiding the emergency stop, and the situation that the mahjong tiles are toppled and dropped due to the emergency stop.

In addition, the support 3 of the present invention is provided with a curved guide wheel 4, the track of the curved guide wheel 4 is a smooth curve, and one end of the lifting swing arm 7 is installed with a roller 16 located in the curved guide wheel 4. In this way, in the present invention, when the lifting swing arm 7 swings, the roller 16 can move in the curved guide groove 4, and simultaneously drives the support 3 to move up and down.

Furthermore, the roller 16 is rotatably connected to the lift swing arm 7 . In this way, in the present invention, when the roller 16 moves in the curved guide groove 4, since it can rotate, it only receives rolling friction instead of sliding friction, so that the upper deck 2 can be raised and lowered more smoothly, and it is not easy to get stuck.

In addition, the driving mechanism of the present invention also includes a driving arm 6 . The driving rack 10 is arranged on one end of the driving arm 6. The driving arm 6 and the driving rack 10 can only move linearly in one direction under the limiting action of the electric mahjong table shell 1. The other end of the driving arm 6 A driving roller 9 is rotatably connected to the upper side, a track groove 8 is provided on the outer side of the driving cam 5 , and the driving roller 9 is located in the track groove 8 . In this way, the present invention uses the track groove 8 to push and drive the driving roller 9, and the driving roller 9 can reduce the friction generated during transmission, thereby making the transmission smoother and less likely to be stuck.

During the working process of the card-raising linkage assembly, the driving cam 5 keeps the rotating state, and drives the driving arm 6 according to the change of the contour line of the driving cam 5. Drive the support 3, because one end of the upper card seat 2 is connected and assembled on the electric mahjong table shell 1, the other end will swing up and down between an angle or level under the traction of the support 3; when the upper card seat 2 is lowered to a suitable angle When in position, the drive arm 6 stops moving, and other components of the electric mahjong table push the mahjong tiles onto the upper deck seat 2, and then drive the cam 5 to control the drive arm 6 to advance, so that the lifting arm 7 lifts the upper deck seat 2 and returns to its original position. Make the mahjong tiles on the upper deck 2 rise to the table smoothly. The words "up", "down", "clockwise" and "counterclockwise" described here are all used in Figure 1. The positional relationship is for reference.

This new model is really novel, progressive and available for industrial use. It should meet the patent application requirements stipulated by the Patent Law of our country. It is no doubt that a new model patent application can be filed in accordance with the law. prayer.
