Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a card loading mechanism for mahjong machines. Background Art

[0002] Automatic mahjong machines have been rapidly promoted because they are convenient for consumers to use. The miniaturization and thinness of mahjong machines have always been an important development trend of mahjong machines. In order to reduce the size of mahjong machines, more and more mahjong machines have been changed from lifting mechanisms to rotating lifting mechanisms.

[0003] The Chinese invention patent with the announcement number CN107773976A disclosed a circular card pushing device of an automatic mahjong machine and an automatic mahjong machine on March 9, 2018, which belongs to the technical field of mahjong machines and solves the problems of large size and complex structure of existing mahjong machines. The circular card pushing device of the utility model includes a motor, a base, a turntable and a card pushing block. The motor is installed on the base, and a circular card pushing groove is provided on the base. The circular card pushing groove is provided with a card inlet and a card outlet. The turntable is located above the base and is driven to rotate by the motor. The turntable drives the card pushing block to push cards in the circular card pushing groove. The use of a rotating card pushing method reduces the space for pushing mahjong cards.

[0004] The Chinese invention patent with announcement number CN107519637B disclosed a mahjong machine and its card loading method on January 5, 2024. The four sets of card picking and handling systems are independently arranged and not staggered. In the card loading component, the card storage slot is curved in a large angle arc, which increases the storage quantity of mahjong tiles in the card storage slot, and greatly reduces the height and manufacturing cost of the mahjong machine host, and the user experience and comfort are better. A cover plate that can be opened upward is set, so that during the rising process of the card lifting pallet, the mahjong tiles on the edge of the card lifting pallet can lift the cover plate. After the card lifting pallet is flush with the mahjong machine table top, the cover plate returns to its position, thus avoiding a large gap between the card lifting pallet and the mahjong machine table top or the edge of the mahjong tiles colliding with the mahjong machine table top.

[0005] The mahjong tiles in the two patents are both raised along a circular track. The circular track is flat, and the push arm is a thin sheet used to push the mahjong tiles onto the table. However, during the rotation of the mahjong tiles, the two sides are always rubbing against the two inner walls of the circular track. If the friction time is too long, the inner wall will become thinner, which will easily cause the tiles to get stuck during the raising process. Summary of the invention

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a mahjong machine card loading mechanism, which aims to solve the technical problem that the cards are easily stuck on the flat annular track in the prior art.

[0007] To achieve the above-mentioned purpose, the utility model proposes a mahjong machine loading mechanism, including an arc-shaped loading track, wherein the arc-shaped loading track is provided with an inlet and an outlet; the arc-shaped loading track includes an inner side wall, an outer side wall and a bottom surface, wherein the inner side wall and the outer side wall are arranged on the bottom surface, the side close to the center position of the arc-shaped loading track is the inner side wall, and the side away from the center position of the arc-shaped loading track is the outer side wall; the side of the bottom surface close to the outer side wall is the outer side, and the end of the bottom surface close to the inner side wall is the inner side, and at least one section of the bottom surface is an inclined surface whose outer side height is higher than the inner side height.

[0008] Preferably, the bottom surface is flat at the outlet and the inlet.

[0009] Preferably, the arc-shaped card loading track is a whole arc, and the slope of the inclined surface of the bottom surface first increases and then decreases from the inlet to the outlet.

[0010] Preferably, the arc-shaped card-loading track is composed of multiple circular arcs connected tangentially, and the slope of the inclined surface of the bottom surface first increases and then decreases from the inlet to the outlet.

[0011] Preferably, the angle formed by the inclined surface and the plane is 0°~75°.

[0012] Preferably, the outer wall is provided with a first slope at the slope, and the first slope is inclined along the height direction of the outer wall toward the inner wall; the inner wall is provided with a second slope at the slope, and the second slope is inclined along the height direction of the inner wall toward the outer wall.

[0013] Preferably, the bottom surface is provided with a first convex strip, the inner side wall is provided with a second convex strip, and the outer side wall is provided with a third convex strip.

[0014] Compared with the prior art, the beneficial effects of the card loading mechanism of a mahjong machine provided by the utility model are as follows:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Many mahjong machines currently use a circular card loading method, such as the prior art cited in the background technology. However, the surface of the circular track of the circular card loading mechanism in the prior art is flat. The push rod for pushing mahjong should be as close to the side of the circular track as possible. The farther away from the center, the harder it is to push. The farther away, the far side of the mahjong will rotate first, and the mahjong has a tendency to rotate, but the width of the track is small, and the mahjong cannot be turned over, causing it to get stuck.

[0031] See also Figure 1-8The embodiment of the utility model provides a mahjong machine card loading mechanism, including an arc-shaped card loading track 1, and the arc-shaped card loading track 1 is provided with an inlet 14 and an outlet 15. The inlet 14 is connected to the stacking mechanism of mahjong, and after the mahjong is stacked, it enters the card loading mechanism from the inlet 14. The outlet 15 is connected to the card lifting mechanism, and the outlet 15 first enters an inclined plate, and then enters the table. The card stacking structure and the card lifting mechanism can be made by the structure of the existing mahjong machine. The arc-shaped card loading track 1 includes an inner side wall 11, an outer side wall 12 and a bottom surface 13, and the bottom surface 13 is provided with the inner side wall 11 and the outer side wall 12, the side close to the center position of the arc-shaped card loading track 1 is the inner side wall 11, and the side away from the center position of the arc-shaped card loading track 1 is the outer side wall 12; the side of the bottom surface 13 close to the outer side wall 12 is the outer side, and the end of the bottom surface 13 close to the inner side wall 11 is the inner side, and at least one section of the bottom surface 13 is a slope whose outer side height is higher than the inner side height.

[0032] After the mahjong enters the bottom surface 13 of the card loading mechanism, the push rod pushes the mahjong to the side close to the center of the card loading mechanism, and the two ends of the mahjong contact the inner wall 11 and the outer wall 12 respectively to be transported to the table. When the mahjong enters the inclined surface of the bottom surface 13, the far end of the mahjong is high and the near end is low, the center of gravity changes, the centrifugal force becomes smaller, and it is not easy to get stuck.

[0033] See also Figure 3 In an optional embodiment, the bottom surface 13 is flat at the exit and the entrance, which is convenient for loading and unloading cards and for cooperating with existing mechanisms. The heights of the exit 15 and the entrance 14 are equal, and the mahjong only changes in position, and the height remains unchanged.

[0034] In an optional embodiment, the bottom surface 13 is a small slope at the outlet 15 and the inlet 14. The outlet 15 and the inlet 14 are slopes with a small inclination, which facilitates the entry of mahjong.

[0035] In an optional embodiment, the arc-shaped card loading track 1 is a whole arc (not shown in the figure), and the arc has a fixed radius. The slope of the inclined surface of the bottom surface 13 increases first and then decreases from the inlet to the outlet. As long as the inlet and the outlet are both flat, the change in the height of the intermediate slope is convenient for conveying mahjong.

[0036] See also Figure 3 In an optional embodiment, the arc-shaped card-loading track 1 is a plurality of circular arcs connected tangentially, and the slope of the inclined surface of the bottom surface 13 increases first and then decreases from the inlet to the outlet. The arc-shaped card-loading track 1 shown in the figure is not a fixed and straight arc, and the center of the middle section is offset, and is closer to the left side relative to the position formed by the previous arc, so that the length of the arc-shaped card-loading track 1 is shortened, which can be more conducive to reducing the overall size of the mahjong machine.

[0037] See also Figure 4 In an optional embodiment, the angle between the inclined surface and the plane is 0° to 75°. Preferably, it is 0° to 15°. If the angle is too large, the mahjong will not be easy to control. The mahjong enters from the entrance 14, and the slope of the inclined surface gradually increases to 15°, and then decreases to 0° to the exit 15.

[0038] See also Figure 4 In an optional embodiment, the outer wall 12 is provided with a first inclined surface at the inclined surface, and the first inclined surface is inclined toward the inner wall 11 along the height direction of the outer wall 12; the inner wall 11 is provided with a second inclined surface at the inclined surface, and the second inclined surface is inclined toward the direction away from the outer wall 12 along the height direction of the inner wall 11. The mahjong is inclined along the inclined surface, and the inner wall 11 and the outer wall 12 provide corresponding moving tracks, and the distance between the two remains unchanged, just passing through the mahjong, to prevent the mahjong from deflecting.

[0039] See also Figure 5 In an optional embodiment, the bottom surface 13 is provided with a first convex strip 131, the inner wall 11 is provided with a second convex strip 111, and the outer wall 12 is provided with a third convex strip 121. By providing each convex strip, the contact area between the mahjong and each surface is reduced, the friction and wear are reduced, and the movement of the mahjong is smoother.

[0040] There are two first convex strips 131, located at the two ends of the bottom surface 13. There are also two second convex strips 111 and two third convex strips 121, the upper and lower strips contact the upper and lower mahjong stacks respectively.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
