DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] Embodiment 1:

[0027] Combination Figure 1 , Figure 2 and Figure 3As shown, the transmission lifting mechanism of the mahjong machine of this embodiment includes a bottom plate 1, a column 2 is arranged on the bottom plate 1, a rotating disk 3 is sleeved on the column 2, a support block 4 is arranged on the top of the column 2, and a lifting device 5 and an adjustment mechanism 6 are arranged on the column 2; the lifting device 5 is used to lift the support block 4 vertically on the top of the column 2; the adjustment mechanism 6 is used to adjust the distance between the support block 4 and the top of the column 2. Specifically, the bottom plate 1 is the basic part of the entire lifting mechanism, which is responsible for carrying the column 2 and all components related thereto. The column 2 is the main supporting structure of the lifting mechanism, which is fixed on the bottom plate 1 and extends upward to support the rotating disk 3 and the support block 4. The support block 4 is located at the top of the column 2 and is used to carry the table top or other components of the mahjong machine. The support block 4 should have sufficient flatness and load-bearing capacity to ensure the stability and flatness of the mahjong machine table. In addition, the support block 4 should also cooperate with the lifting device 5 and the adjustment mechanism 6 to achieve the functions of vertical lifting and spacing adjustment. The lifting device 5 is a key component for realizing the vertical lifting of the support block 4 on the top of the column 2. It can realize the lifting function by driving methods such as motors, cylinders, and screws. The lifting device 5 should have precise control capabilities and a smooth lifting speed to ensure the stability and safety of the mahjong machine during the lifting process. The adjustment mechanism 6 is used to adjust the spacing between the support block 4 and the top of the column 2. This can be achieved by adjusting the stroke of the lifting device 5, using gaskets or adjusting screws. The adjustment mechanism 6 should be flexible and accurate to meet the changes in the height of the table top of different mahjong machines or the needs of players. In addition, in order to ensure the safety and reliability of the lifting mechanism, limit switches or sensors are set in the lifting device 5 and the adjustment mechanism 6 to prevent excessive lifting or accidental collision during the lifting process.

[0028] Combination Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the lifting device 5 includes a motor base 51 mounted on the bottom plate 1, a rotating motor 52 is mounted on the motor base 51, a rocker arm 53 is fixedly connected to the output end of the rotating motor 52, a swing arm 54 is arranged above the bearing of the rocker arm 53, a stopper 55 is arranged above the bearing of the swing arm 54, a lifting tube 56 is arranged on the top of the stopper 55, and the top of the lifting tube 56 is fixedly connected to the support block 4. Specifically, the design of the lifting device 5 provides power and control for the transmission lifting mechanism of the mahjong machine, ensuring the vertical lifting function of the support block 4. The motor base 51 is mounted on the bottom plate 1 as a support and fixing base for the rotating motor 52. The rotating motion of the rotating motor 52 is converted into the vertical lifting motion of the support block 4 through the transmission mechanism. The rocker arm 53 is fixedly connected to the output end of the rotating motor 52, and the bearing of the swing arm 54 is located above the rocker arm 53. Its design allows the swing arm 54 to generate corresponding swings when the rocker arm 53 rotates. The swing amplitude and frequency of the swing arm 54 need to match the lifting operation to ensure the smoothness and accuracy of the lifting process. The stopper 55 is located above the bearing of the swing arm 54, and its function is to limit the swing amplitude of the swing arm 54 and prevent it from swinging too much, which may cause damage to the lifting tube 56 or instability in the lifting operation. The top of the lifting tube 56 is fixedly connected to the support block 4, and is a key component connecting the lifting device 5 and the support block 4. When the rotary motor 52 is working, the lifting tube 56 generates a vertical lifting motion through the interaction of the rocker arm 53, the swing arm 54 and the stopper 55, thereby driving the lifting of the support block 4.

[0029] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a lifting groove 21 is provided inside the column 2, and protrusions 551 are provided on both sides of the stopper 55, and the protrusions 551 can move up and down in the lifting groove 21. Specifically, in the transmission lifting mechanism of the mahjong machine, the stability and accuracy of the lifting device 5 are enhanced by providing the lifting groove 21 inside the column 2 and providing the protrusions 551 on both sides of the stopper 55. The lifting groove 21 is provided inside the column 2, and its shape and size match the protrusions 551. The lifting groove 21 provides a fixed track, so that the protrusions 551 can move up and down therein, thereby guiding the stopper 55, and the lifting tube 56 and the support block 4 connected thereto to perform vertical lifting movement. The protrusions 551 are provided on both sides of the stopper 55, and are designed to work in conjunction with the lifting groove 21. The shape and size of the protrusions 551 need to accurately match the lifting groove 21 to ensure smooth movement during the lifting process without jamming or offset. When the rotary motor 52 is started, the stopper 55 drives the protrusion 551 to move up and down in the lifting slot 21 through the interaction between the rocker arm 53 and the swing arm 54 .

[0030] Combination Figure 3 , Figure 4 and Figure 6As shown, the adjusting mechanism 6 includes an adjusting nut 61 installed at the top of the column and threadedly connected thereto, the top of the adjusting nut 61 conflicts with the bottom of the support block 4, and the distance between the support block 4 and the top of the column 2 can be adjusted by twisting the adjusting nut 61. Specifically, in the transmission lifting mechanism of the mahjong machine, the design of the adjusting mechanism 6 allows the user to accurately adjust the distance between the support block 4 and the top of the column 2 by threaded connection, thereby ensuring the stability and adaptability of the mahjong machine during use. The adjusting nut 61 is installed at the top of the column 2 and threadedly connected to the top of the column 2. This connection method allows the adjusting nut 61 to move up and down on the column 2, thereby adjusting the distance between the support block 4 and the top of the column 2. By rotating the adjusting nut 61, the user can easily change its position relative to the top of the column 2. The top of the adjusting nut 61 conflicts with the bottom of the support block 4.

[0031] A magnetron plate 511 is provided on the motor base 51, and a first Hall sensor 512 and a second Hall sensor 513 are provided at both ends of the magnetron plate 511, respectively, and a signal magnet 531 is provided on the rocker arm 53. Specifically, in the transmission lifting mechanism of the mahjong machine, by providing the magnetron plate 511 and the corresponding Hall sensor on the motor base 51, combined with the signal magnet 531 on the rocker arm 53, a precise position detection and feedback mechanism is realized. The magnetron plate 511 is installed on the motor base 51 for interacting with the signal magnet 531 on the rocker arm 53. The first Hall sensor 512 is located at one end of the magnetron plate 511, and when the signal magnet 531 passes by, it can sense the change in the magnetic field and generate a corresponding electrical signal. This signal can be used to detect the initial position or a specific position of the rocker arm 53. The second Hall sensor 513 is located at the other end of the magnetron plate 511, and is similar to the first Hall sensor 512, and is also used to detect the passage of the signal magnet 531, but is usually used to detect another position of the rocker arm 53, such as the end point or the middle position of the lifting. By reading the output signal of the Hall sensor, the control system can accurately know the current position of the support block 4 and perform corresponding lifting or stopping operations accordingly. This helps to improve the accuracy and reliability of the lifting mechanism of the mahjong machine and also enhances the user experience.

[0032] The first Hall sensor 512 senses the signal magnet 531, the rotating motor 52 stops rotating, the lifting tube 56 and the support block 4 rise to their proper positions, and the second Hall sensor 513 senses the signal magnet 531, the rotating motor 52 stops rotating, and the lifting tube 56 and the support block 4 fall to their proper positions. When the user or the control system issues an ascending command, the rotating motor 52 starts rotating, driving the rocker arm 53 to rotate. As the rocker arm 53 rotates, the signal magnet 531 also moves with it. When the signal magnet 531 moves to the position of the first Hall sensor 512 on the magnetron plate 511, the first Hall sensor 512 senses the change in the magnetic field and outputs an electrical signal. After receiving the electrical signal from the first Hall sensor 512, the control system determines that the lifting tube 56 and the support block 4 have risen to their proper positions, and thus controls the rotating motor 52 to stop rotating. When the user or the control system issues a descending command, the rotating motor 52 starts rotating again, but this time in the reverse direction, to drive the rocker arm 53 to rotate in the reverse direction. As the rocker arm 53 rotates in the reverse direction, the signal magnet 531 moves again. When the signal magnet 531 moves to the position of the second Hall sensor 513 on the magnetron plate 511, an electrical signal is output. After receiving the electrical signal from the second Hall sensor 513, the control system determines that the lifting tube 56 and the support block 4 have been lowered to the position, and then controls the rotating motor 52 to stop rotating. Through the cooperation of the Hall sensor and the signal magnet, the position of the lifting tube 56 and the support block 4 can be accurately detected, thereby achieving precise control.

[0033] Embodiment 2:

[0034] Compared with Example 1, Figure 1 to Figure 4 As shown, in this embodiment, a main bearing 9 is provided between the rotating disk 3 and the column 2. Specifically, in the transmission lifting mechanism of the mahjong machine, the main bearing 9 is provided between the rotating disk 3 and the column 2 to ensure that the rotating disk 3 can rotate steadily and smoothly. The main bearing 9 provides stable support for the rotating disk 3 and determines its rotation center relative to the column 2.

[0035] A servo motor 7 is provided on the bottom plate 1, and a transmission gear 8 is connected to the output end of the servo motor 7, and the transmission gear 8 is gear-driven with the rotating disk 3. Specifically, in the transmission lifting mechanism of the mahjong machine, by arranging the servo motor 7 on the bottom plate 1, and connecting the output end of the servo motor 7 with the transmission gear 8, and allowing the transmission gear 8 to perform gear transmission with the rotating disk 3, the servo motor 7 can respond quickly and accurately according to the control signal. In the transmission lifting mechanism of the mahjong machine, the servo motor 7 is used to drive the rotation of the rotating disk 3. The transmission gear 8 is used to transmit the rotational motion of the servo motor 7 to the rotating disk 3, and to amplify or reduce the torque and speed of the rotation. Through gear transmission, the torque output by the servo motor 7 can be amplified, so that the rotating disk 3 can withstand a larger load. Both the servo motor 7 and the gear transmission have high reliability and stability, which can ensure the long-term stable operation of the mahjong machine.

[0036] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
