Technical Field

[0001] The invention belongs to the field of entertainment equipment and relates to an automatic mahjong machine, in particular to a control panel mounting assembly of an automatic mahjong machine. Background Art

[0002] The automatic mahjong machine is a modern entertainment device that integrates multiple functions such as shuffling, stacking, and sorting cards. It greatly simplifies the preparation process of the traditional mahjong game and improves the efficiency and fun of the game.

[0003] Existing mahjong machines, such as an automatic mahjong machine disclosed in the China Patent Library (application number: 202010333068.7), include legs and a chassis body. The chassis body includes a box body, a shuffling mechanism, a mid-lifting mechanism and a control disk mechanism. The box body includes a bottom plate. The shuffling mechanism includes a large disk drive assembly, a large disk, a card dial and a fixed seat. The mid-lifting mechanism includes a mid-lifting driver and a lifting rod. The lifting rod is vertically slidably connected to the fixed seat. The middle part of the large disk is arched upward, and an accommodating space is formed between the upward arch of the middle part of the large disk and the bottom plate. The fixed seat, the large disk drive assembly, and the mid-lifting driver are all located in the accommodating space. An inner gear ring is provided on the large disk. The large disk drive assembly includes a large disk driver and a reducer. The reducer includes an input gear and an output gear. The large disk driver drives the input gear to rotate, and the output gear is meshed with the inner gear ring of the large disk.

[0004] In the above-mentioned mahjong machine, the mechanism for adjusting the height of the control disk mechanism and the mechanism for axially positioning the large disk are locked separately, which increases the entire assembly steps and is not conducive to assembly. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide an automatic mahjong machine control panel installation component that is easy to assemble.

[0006] The purpose of the present invention can be achieved through the following technical solutions: an automatic mahjong machine control panel mounting assembly, including a shuffling plate, a control plate and a hollow column, a center tube is vertically slidably arranged in the column, the upper end of the center tube extends out of the column and is fixedly connected to the control plate, the shuffling plate is rotatably arranged on the column through a bearing, the bearing includes an inner ring fixedly connected to the column and an outer ring fixedly connected to the shuffling plate, a pressure cap is threadedly connected to the upper end of the column, and is characterized in that the lower end of the pressure cap directly presses against the top of the inner ring; an externally threaded tube is formed on the top of the column, and the externally threaded tube is sleeved on the outside of the center tube; a top cap for lifting the control plate is threadedly connected to the externally threaded tube, the lower end of the top cap extends into the pressure cap, and the spiral directions of the top cap and the pressure cap are opposite; a threaded hole is radially penetrated on the side wall of the pressure cap, a screw is screwed into the threaded hole, and the screw rod is tightly pressed on the top cap.

[0007] The spiral directions of the top cap and the pressure cap are opposite to each other to form mutual restraint. In this way, only one screw needs to be screwed in to limit the pressure cap and the top cap circumferentially at the same time, which effectively simplifies the assembly steps and has the advantages of simple structure and easy assembly.

[0008] In the above-mentioned automatic mahjong machine control disk mounting assembly, the rotation direction that forces the pressure cap to move downward is the same as the rotation direction of the shuffling disk, so that the pressure cap always has a tendency to move downward and press the inner ring of the bearing when the shuffling disk rotates, thereby simultaneously strengthening the strength of the circumferential locking of the pressure cap and the top cap, ensuring a more stable operation of the mahjong machine.

[0009] In the above-mentioned automatic mahjong machine control panel mounting assembly, the inner wall of the top cap at the upper port is a conical surface with a diameter gradually decreasing from top to bottom, and the outer wall of the lower end of the control panel has a section of annular surface, the axial section of the annular surface is an arc shape matching the conical surface, and the conical surface is pressed on the annular surface. The top cap and the control panel are in contact and matched through the conical surface and the arc-shaped annular surface, which can improve the matching accuracy of the top cap and the control panel, and realize stable and accurate lifting and lowering of the control panel.

[0010] In the above-mentioned automatic mahjong machine control panel mounting assembly, the outer side surface of the pressing cap is tapered, and the diameter of the outer side surface of the pressing cap gradually increases from top to bottom to increase the holding area of ​​the pressing cap and facilitate the rotation and adjustment of the pressing cap.

[0011] In the above automatic mahjong machine control panel mounting assembly, a circle of strip grooves evenly distributed along the circumference of the pressing cap is provided on the outer side of the pressing cap, and the length of the strip grooves extends along the inclined direction of the outer side of the pressing cap. The provision of the strip grooves can increase the roughness of the outer side of the pressing cap, making it easier to adjust the pressing cap.

[0012] In the above-mentioned automatic mahjong machine control panel mounting assembly, a guide sleeve matching the center tube is fixed in the column, and the guide sleeve is sleeved on the outside of the center tube; a long strip-shaped rocker arm contact portion is horizontally formed on one side of the lower end of the center tube, and two first guide portions and two second guide portions, both in the shape of long strips, are vertically formed on the inner wall of the column, and the two first guide portions and the two second guide portions are arranged side by side along the length direction of the rocker arm contact portion; a guide block is horizontally formed on the other side of the lower end of the center tube, and the two first guide portions are respectively pressed against the two sides of the guide block; the second guide portion is between the first guide portion and the rocker arm contact portion, and the two second guide portions are respectively pressed against the side walls at both ends of the rocker arm contact portion.

[0013] With the cooperation of the guide sleeve, the first guide part and the second guide part, a stable and reliable up and down sliding cooperation is formed between the central tube and the column, thereby improving the stability and accuracy of the lifting and lowering of the control panel.

[0014] The first guide part and the second guide part are directly formed on the inner wall of the column to contact the central tube, so that the cooperation between the central tube and the column completely depends on its own structure, which has the advantages of simple structure, stable operation, etc.

[0015] At the same time, two first guide parts and two second guide parts are provided to form a plurality of support limit points between the central tube and the column, thereby slowing down the wear rate of each support position and greatly improving the working stability and service life of the guide structure.

[0016] In the above-mentioned automatic mahjong machine control panel installation assembly, the above-mentioned first guide part and the second guide part are both rod-shaped structures. On the premise of ensuring that the column and the center tube form a stable fit, the contact area between the column and the center tube can be reduced, further improving the life and working stability of the guide structure.

[0017] In the above-mentioned automatic mahjong machine control panel mounting assembly, the cross-sections of the first guide portion and the second guide portion are both arc-shaped, which can ensure the strength of the first guide portion and the second guide portion and make the contact area between the column and the center tube smaller.

[0018] In the above-mentioned automatic mahjong machine control panel mounting assembly, the column is an injection-molded integral part, which is not only convenient for processing but also can greatly reduce the cost.

[0019] In the above-mentioned automatic mahjong machine control panel mounting assembly, a circle of arc-shaped convex strips is formed on the outer wall of the upper end of the top cap, the arc-shaped convex strips extend up and down, and the circle of arc-shaped convex strips are evenly spaced along the circumference of the top cap. The provision of the arc-shaped convex strips can increase the surface roughness of the upper end of the top cap, which is conducive to the rotation of the top cap to adjust the height of the control panel.

[0020] Compared with the prior art, the automatic mahjong machine control panel installation assembly has the following advantages: 1. The spiral directions of the top cap and the pressure cap are opposite to each other to form mutual restraint. In this way, only one screw needs to be screwed in to limit the pressure cap and the top cap circumferentially at the same time, which effectively simplifies the assembly steps and has the advantages of simple structure and easy assembly.

[0021] 2. The rotation direction of the pressing cap that forces it to move downward is the same as the rotation direction of the shuffling disk, so that the pressing cap always has a tendency to move downward and press the inner ring of the bearing when the shuffling disk rotates, thereby simultaneously strengthening the strength of the circumferential locking of the pressing cap and the top cap to ensure a more stable operation of the mahjong machine.

[0022] 3. The first guide part and the second guide part are directly formed on the inner wall of the column to contact the center tube, so that the cooperation between the center tube and the column completely depends on its own structure, which has the advantages of simple structure and stable operation. At the same time, two first guide parts and two second guide parts are set to form multiple support limit points between the center tube and the column, thereby delaying the wear speed of each support position and greatly improving the working stability and life of the guide structure.

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figures 1 to 3 As shown, the control panel installation assembly of the automatic mahjong machine includes a shuffling plate 1, a control plate 2 and a hollow column 3.

[0031] in, A central tube 4 is vertically slidably disposed in the column 3 , and an upper end of the central tube 4 extends out of the column 3 and is fixedly connected to the control panel 2 .

[0032] like Figure 2 and Figure 3 As shown, the shuffle plate 1 is rotatably arranged on the column 3 through the bearing 5, and the bearing 5 is a ball bearing 5, and the bearing 5 includes an inner ring 5a fixedly connected to the column 3 and an outer ring fixedly connected to the shuffle plate 1. Specifically, a ring-shaped bearing 5 seat 1a is formed at the inner wall of the top of the shuffle plate 1, and the bearing 5 seat 1a is coaxially arranged with the shuffle plate 1. The axial cross-section of the bearing 5 seat 1a is L-shaped, and the outer ring of the bearing 5 is located in the bearing 5 seat 1a and pressed on the bottom wall of the bearing 5 seat 1a to facilitate the installation of the bearing 5. Further explanation, a circle of triangular reinforcing ribs is formed between the outer wall of the bearing 5 seat 1a and the inner wall of the shuffle plate 1 to strengthen the strength of the bearing 5 seat 1a itself and ensure that the shuffle plate 1 rotates more stably. In the actual product, the inner ring 5a and the outer ring of the bearing 5 are respectively fixed to the column 3 and the bearing 5 seat 1a by interference fit.

[0033] like Figure 2 and Figure 3 As shown, a pressure cap 6 is screwed on the upper end of the column 3, and the lower end of the pressure cap 6 directly presses against the top of the inner ring 5a. The pressure cap 6 cooperates with the bearing 5 seat 1a to stabilize the bearing 5 in the axial direction. An external threaded tube 3a is formed on the top of the column 3. The external threaded tube 3a and the column 3 are coaxially arranged, and the external threaded tube 3a is sleeved outside the center tube 4. A top cap 7 for lifting the control panel 2 is threadedly connected to the external threaded tube 3a, and the lower end of the top cap 7 extends into the pressure cap 6, and the spiral directions of the top cap 7 and the pressure cap 6 are opposite. A threaded hole is radially penetrated on the side wall of the pressure cap 6, and a screw 8 is screwed into the threaded hole, and the rod of the screw 8 is tightly pressed on the top cap 7.

[0034] The spiral directions of the top cap 7 and the pressure cap 6 are opposite to each other to form mutual restraint. In this way, only one screw 8 needs to be screwed in to circumferentially limit the pressure cap 6 and the top cap 7 at the same time, which effectively simplifies the assembly steps and has the advantages of simple structure and easy assembly.

[0035] It is further explained that the rotation direction forcing the pressure cap 6 to move downward is the same as the rotation direction of the shuffling disk 1, so that the pressure cap 6 always has a tendency to move downward to tighten the inner ring 5a of the bearing 5 when the shuffling disk 1 rotates, thereby simultaneously strengthening the strength of the circumferential locking of the pressure cap 6 and the top cap 7 to ensure a more stable operation of the mahjong machine.

[0036] In this embodiment, like Figure 3 and Figure 4 As shown, the top cap 7 and the control panel 2 cooperate in the following manner: the inner wall of the top cap 7 at the upper port is a conical surface 7a whose diameter gradually decreases from top to bottom, and the outer wall of the lower end of the control panel 2 has a section of annular surface 2a, the axial section of the annular surface 2a is an arc shape matching the conical surface 7a, and the conical surface 7a is pressed on the annular surface 2a. The top cap 7 and the control panel 2 are in contact and cooperation through the conical surface 7a and the arc-shaped annular surface 2a, which can improve the cooperation accuracy of the top cap 7 and the control panel 2, and realize the stable and accurate lifting and lowering of the control panel 2.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, the matching mode of the column 3 and the center tube 4 is as follows: a guide sleeve 9 matching the center tube 4 is fixed inside the column 3, and the guide sleeve 9 is sleeved outside the center tube 4. A long strip-shaped rocker arm contact portion 4a is horizontally formed on one side of the lower end of the center tube 4, and two first guide portions 3b and two second guide portions 3c, both of which are long strips, are vertically formed on the inner wall of the column 3, wherein the two first guide portions 3b are arranged side by side along the length direction of the rocker arm contact portion 4a; the two second guide portions 3c are also arranged side by side along the length direction of the rocker arm contact portion 4a. A guide block 4b is horizontally formed on the other side of the lower end of the center tube 4, and the two first guide portions 3b are respectively pressed on both sides of the guide block 4b. The second guide portion 3c is between the first guide portion 3b and the rocker arm contact portion 4a, and the two second guide portions 3c are respectively pressed on the side walls at both ends of the rocker arm contact portion 4a.

[0038] With the cooperation of the guide sleeve 9, the first guide portion 3b and the second guide portion 3c, a stable and reliable up-and-down sliding cooperation is formed between the central tube 4 and the column 3, thereby improving the lifting stability and accuracy of the control panel 2.

[0039] The first guide part 3b and the second guide part 3c are directly formed on the inner wall of the column 3 to contact the central tube 4, so that the cooperation between the central tube 4 and the column 3 completely depends on its own structure, which has the advantages of simple structure and stable operation. At the same time, two first guide parts 3b and two second guide parts 3c are provided to form multiple support limit points between the central tube 4 and the column 3, thereby delaying the wear speed of each support position and greatly improving the working stability and life of the guide structure.

[0040] Further explanation: both the first guide portion 3b and the second guide portion 3c are rod-shaped structures, which can reduce the contact area between the column 3 and the center tube 4 while ensuring a stable fit between the column 3 and the center tube 4, further improving the life and working stability of the guide structure. Preferably, the cross-sections of the first guide portion 3b and the second guide portion 3c are both arc-shaped, which can ensure the strength of the first guide portion 3b and the second guide portion 3c and make the contact area between the column 3 and the center tube 4 smaller.

[0041] In this embodiment, The column 3 is an injection-molded integral part, which is not only convenient for processing but also can greatly reduce the cost.

[0042] The central tube 4 is an integrated structure.

[0043] like Figure 5 As shown, the structure of the guide block 4b is as follows: the guide block 4b has a weight-reducing opening 4b1 which is vertically penetrated to reduce the overall weight of the center tube 4. Further explanation, the guide block 4b includes two horizontally arranged plates 4b2, and the two plates 4b2 are arranged side by side along the length direction of the rocker arm contact portion 4a, one end of the two plates 4b2 extends to the center tube 4, and the other ends of the two plates 4b2 are connected by a connecting rod. The center tube 4, the connecting rod and the two plates 4b2 form the above-mentioned weight-reducing opening 4b1, and the opposite sides of the two plates 4b2 are in contact with the two first guide portions 3b respectively. The above-mentioned design can effectively expand the area of ​​the weight-reducing opening 4b1 and further reduce the weight of the center tube 4. In the actual product, the guide block 4b is in the shape of a long strip, and the length extension direction of the guide block 4b and the rocker arm contact portion 4a is perpendicular.

[0044] like Figure 4As shown, the outer side of the pressing cap 6 is tapered, and the diameter of the outer side of the pressing cap 6 gradually increases from top to bottom to increase the gripping area of ​​the pressing cap 6 and facilitate the rotation and adjustment of the pressing cap 6. Further explanation, a circle of strip grooves 6a uniformly distributed along the circumference of the pressing cap 6 is provided on the outer side of the pressing cap 6, and the length of the strip grooves 6a extends along the inclined direction of the outer side of the pressing cap 6. The provision of the strip grooves 6a can increase the roughness of the outer side of the pressing cap 6, making it easier to adjust the pressing cap 6.

[0045] A circle of arc-shaped convex strips 7b is formed on the outer wall of the upper end of the top cap 7, and the arc-shaped convex strips 7b extend up and down, and the circle of arc-shaped convex strips 7b are evenly spaced along the circumference of the top cap 7. The arrangement of the arc-shaped convex strips 7b can increase the surface roughness of the upper end of the top cap 7, which is conducive to the rotation of the top cap 7 to adjust the height of the control disk 2.

[0046] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
