[0031] It should be noted that, without conflict, the features in the embodiments of this utility model may be combined with each other.

[0032] Please refer to Figure 1 , the card-lifting mechanism 100 and the mahjong machine provided in the embodiments of this utility model can solve the above problems, and the following will describe them in detail.

[0033] The card-lifting mechanism 100 includes a card-lifting support 110, a driving member 120, a first rotating arm 130, a second rotating arm 140, a support block 150 and a fixed support 160; wherein, the driving member 120 is connected to the first rotating arm 130 and drives the first rotating arm 130 to rotate, the fixed support 160 is rotatably connected to the second rotating arm 140, both ends of the support block 150 are respectively connected to the first rotating arm 130 and the second rotating arm 140, and the support block 150 is used to rotate with the first rotating arm 130 and abut against the card-lifting support 110 to drive the card-lifting support 110 to perform a lifting motion.

[0034] During the working process, the driving member 120 provides power to drive the first rotating arm 130 to rotate, so that the support block 150 rotates synchronously, and then drives the card-lifting support 110 to perform a lifting motion. The fixed support 160 is used to support the second rotating arm 140. The first rotating arm 130 and the second rotating arm 140 are respectively located at both ends of the support block 150, so that the support block 150 maintains balance and avoids skewing during the process of abutting against the fixed support 160, ensuring that the card-lifting support 110 does not skew, and further avoiding the occurrence of abnormal card-lifting phenomena, preventing the cards from jamming, and improving the use experience of the mahjong machine.

[0035] It should be noted that the extending direction of the support block 150 is perpendicular to the card-lifting bracket 110. Therefore, the first swing arm 130 and the second swing arm 140 are respectively located on both sides of the card-lifting bracket 110, thereby preventing the card-lifting bracket 110 from deflecting towards both sides during operation.

[0036] In addition, the numbers of the driving member 120, the first swing arm 130, the second swing arm 140, the support block 150, and the fixing bracket 160 are all two groups, and they are respectively arranged at both ends of the card-lifting bracket 110, so that there are two support blocks 150 respectively supporting and holding the lower sides of both ends of the card-lifting bracket 110 during the card-lifting operation, further preventing the card-lifting bracket 110 from deflecting towards both ends during operation.

[0037] Reference Figure 1 , in order to avoid interference during the descending process of the card-lifting bracket 110, the first swing arm 130 and the second swing arm 140 can be arranged in parallel at intervals to form a limiting cavity 135, and the limiting cavity 135 is used to accommodate the card-lifting bracket 110.

[0038] That is, when the card-lifting bracket 110 moves downward, the bottom end of the card-lifting bracket 110 can be accommodated in the limiting cavity 135. On the one hand, interference is avoided, and on the other hand, the limiting cavity 135 can play a role in limiting and accommodating the card-lifting bracket 110. When the card-lifting bracket 110 has a tendency to deflect towards both sides, the first swing arm 130 and the second swing arm 140 forming the limiting cavity 135 can play a limiting role on the card-lifting bracket 110, and the deflection tendency of the card-lifting bracket 110 can be slowed down, so that the deflection amplitude of the tilted card-lifting bracket 110 during the upward movement (i.e., the card-lifting action) can be slowed down. Thus, in the case where maintenance cannot be carried out in time, the card-lifting mechanism 100 can continue the card-lifting operation without the deflection tendency gradually increasing due to continuous operation.

[0039] Reference Figure 1 , in order to improve the contact smoothness between the support block 150 and the card-lifting bracket 110 and reduce the movement friction, the support block 150 can be made cylindrical. Both ends of the support block 150 are rotatably matched with the first swing arm 130 and the second swing arm 140 at the same time, and the support block 150 is in rolling cooperation with the card-lifting bracket 110.

[0040] At the same time, the support block 150 can also be made spherical, thereby having smaller movement friction; however, it is preferably that the support block 150 is cylindrical to ensure that the support block 150 has a sufficient contact area with the card-lifting bracket 110 for supporting.

[0041] Reference Figure 1 and Figure 2, in order to make the card-lifting movement process of the card-lifting bracket 110 more adaptable to the rotational movement of the support block 150, a guiding surface 111 can be formed on the card-lifting bracket 110, and the support block 150 is in contact with the guiding surface 111.

[0042] Specifically, the guiding surface 111 is arc-shaped, and there are two guiding surfaces 111 corresponding to the same support block 150. When the support block 150 is at the highest point, the two guiding surfaces 111 are respectively located on both sides of the support block 150. During the movement of the support block 150 and the card-lifting bracket 110, the support block 150 can move along the guiding surface 111, stably supporting the card-lifting bracket 110 while making the lifting movement of the card-lifting bracket 110 smoother.

[0043] Reference Figure 1 and Figure 2 , in order to prevent the support block 150 from deviating from the card-lifting bracket 110 from one side, a guiding groove 112 can be formed on the card-lifting bracket 110, and the guiding surface 111 is connected to the mouth of the guiding groove 112.

[0044] The guiding groove 112 is U-shaped, and the U opening is inclined downward. When the support block 150 moves to the leftmost or rightmost side, it will contact the bottom of the guiding groove 112, and the side walls of the guiding groove 112 can also play a guiding and limiting role for the support block 150, so that the support block 150 can contact the guiding surface 111 before and after contacting the guiding groove 112, thereby ensuring the smoothness of the cooperation between the support block 150 and the card-lifting bracket 110, and better converting the rotational movement of the support block 150 into the lifting movement of the card-lifting bracket 110.

[0045] Reference Figure 1 and Figure 2 , the card-lifting mechanism 100 further includes a card-lifting plate 170, and the card-lifting plate 170 is connected to the card-lifting bracket 110.

[0046] During the card-lifting operation process, the card-lifting plate 170 is closer to the card body. The width and extension length of the card-lifting plate 170 are both greater than those of the card-lifting bracket 110, and the card-lifting plate 170 is detachably connected to the card-lifting bracket 110, which not only facilitates maintenance but also reduces the overall size and helps to reduce the weight of the mahjong machine.

[0047] Reference Figure 1 and Figure 2 , in order to further ensure the relative structural stability among the card-lifting bracket 110, the card-lifting plate 170, and the fixed bracket 160, the card-lifting mechanism 100 can further include a support seat 180. The support seat 180 is connected to the fixed bracket, and the card-lifting plate 170 is movably connected to the support seat 180.

[0048] Specifically, the support base 180 is provided with a guiding hole 181, and the card-lifting mechanism 100 further includes a guiding rod 190. One end of the guiding rod 190 is connected to the card-lifting plate 170, and the other end of the guiding rod 190 is received in the guiding hole 181. The extending direction of the guiding hole 181, the extending direction of the guiding rod 190, and the moving direction of the card-lifting plate 170 are the same.

[0049] During the card-lifting movement, when the card-lifting plate 170 rises with the card-lifting bracket 110, the guiding rod 190 extends out of the guiding hole 181; when the card-lifting plate 170 descends with the card-lifting bracket 110, the guiding rod 190 retracts into the guiding hole 181. Through the guiding structure of the guiding rod 190 and the guiding hole 181, the card-lifting movement of the card-lifting bracket 110 and the card-lifting plate 170 can be further guided to prevent the two from easily deflecting.

[0050] In addition, the card-lifting bracket 110, the card-lifting plate 170, the guiding rod 190, the support base 180, the fixed bracket 160, the second swing arm 140, the support block 150, and the first swing arm 130 can jointly form a closed-loop structure, making the system strength and stiffness of the overall card-lifting mechanism 100 better, and further ensuring the sustainable operation of the card-lifting movement.

[0051] An embodiment of the present invention further provides a mahjong machine, including a table body and the card-lifting mechanism 100. The driving member 120 and the fixed bracket 160 are both arranged on the table body. Specifically, the table body has four sides, and corresponding card-lifting mechanisms 100 can be respectively arranged on the four sides, and the driving members 120 in the four card-lifting mechanisms 100 can communicate to operate synchronously, thereby ensuring the synchronous card-lifting operation on the mahjong machine.

[0052] The mahjong machine includes a card-lifting mechanism 100, which has all the functions of the card-lifting mechanism 100.

[0053] In summary, the card-lifting mechanism 100 and the mahjong machine provided by the embodiments of the present invention at least have the following advantages:

[0054] (1) The first swing arm 130 and the second swing arm 140 are respectively located at both ends of the support block 150, so that the support block 150 maintains balance and avoids deflection during the process of abutting against the fixed bracket 160, ensuring that the card-lifting bracket 110 does not deflect towards both sides, thereby avoiding the occurrence of abnormal card-lifting phenomena, preventing card jamming, and improving the use experience of the mahjong machine.

[0055] (2) By respectively arranging support blocks 150 at the lower ends on both sides of the card-lifting bracket 110, the card-lifting bracket 110 can be further prevented from deflecting towards both ends during the working process.

[0056] (3) By forming a limiting cavity 135 between the first swing arm 130 and the second swing arm 140, on the one hand, interference is avoided, and on the other hand, the limiting cavity 135 can play a role in limiting and accommodating the card-lifting bracket 110. When the card-lifting bracket 110 has a tendency to deflect towards both sides, the first swing arm 130 and the second swing arm 140 forming the limiting cavity 135 can play a limiting role on the card-lifting bracket 110, and can slow down the deflection tendency of the card-lifting bracket 110, so that the deflection amplitude of the inclined card-lifting bracket 110 during the ascending movement (i.e., the card-lifting action) can be slowed down. Furthermore, in the case where maintenance cannot be carried out in time, the card-lifting mechanism 100 can continue to perform the card-lifting operation, and the deflection tendency will not gradually increase due to continuous operation.

[0057] (4) By making the support block 150 cylindrical, both ends of the support block 150 are rotationally matched with the first swing arm 130 and the second swing arm 140 at the same time, and the support block 150 is in rolling fit with the card-lifting bracket 110, which can improve the contact smoothness between the support block 150 and the card-lifting bracket 110 and reduce the movement friction.

[0058] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
