DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0027] like Figures 1 to 3 As shown, an embodiment of the utility model provides a card flipping mechanism, including a mounting frame 210 for mounting on a connecting plate 100 of a mahjong machine, and a magnet assembly 220 for magnetically flipping cards; the mounting frame 210 is provided with a first mounting groove 2111 and a second mounting groove 212; the magnet assembly 220 includes a first magnet 221 clamped in the first mounting groove 2111 and a second magnet 222 clamped in the second mounting groove 212.

[0028] It can be understood that the card flipping mechanism is installed on the connecting plate 100 of the mahjong machine through the mounting frame 210, and the shuffling turntable of the mahjong machine (not shown) is located above the card flipping mechanism, so that the mahjong tiles in the shuffling turntable can be flipped by the magnetism of the magnet assembly 220 so that the mahjong tiles face down, thereby facilitating the stacking of mahjong tiles. The side of the first magnet 221 facing away from the connecting plate 100 has the same polarity as the side of the second magnet 222 facing away from the connecting plate 100, so there is a repulsive force between the first magnet 221 and the second magnet 222. The first magnet 221 is clamped in the first mounting groove 2111 and is magnetically adsorbed on the connecting plate 100, so that the first magnet 221 can be fixed in the first mounting groove 2111 to prevent the first magnet 221 from being displaced under the repulsive force of the second magnet 222. The second magnet 222 is clamped in the second mounting groove 212 and is magnetically adsorbed on the connecting plate 100, so that the second magnet 222 can be fixed in the second mounting groove 212 to prevent the second magnet 222 from being displaced under the repulsive force of the first magnet 221. The shape of the first magnet 221 can be set according to actual conditions, as long as the mahjong tiles in the mahjong machine can be turned over by magnetism. The shape of the first mounting groove 2111 corresponds to the first magnet 221, so that the first magnet 221 can be clamped in the first mounting groove 2111. The shape of the second magnet 222 can be set according to actual conditions, as long as the mahjong tiles in the mahjong machine can be turned over by magnetism. The shape of the second mounting groove 212 corresponds to the second magnet 222, so that the second magnet 222 can be clamped in the second mounting groove 212. In one embodiment, the first magnet 221 and the second magnet 222 are both rectangular, so as to correspond to the shape of the mahjong tiles, so as to facilitate the turning of the mahjong tiles.

[0029] In the card flipping mechanism of the present invention, a mounting frame 210 is arranged on the connecting plate 100 of the mahjong machine, and a first mounting groove 2111 for clamping the first magnet 221 and a second mounting groove 212 for clamping the second magnet 222 are arranged on the mounting frame 210, thereby avoiding relative displacement between the first magnet 221 and the second magnet 222 due to the repulsive force. At the same time, the effective area of ​​the magnetic field through the magnetic card flipping is increased by the first magnet 221 and the second magnet 222, thereby improving the card flipping efficiency of the mahjong machine.

[0030] like Figure 1As shown, in one embodiment, the centroids of the first magnet 221 and the second magnet 222 are located on an arc with the same preset radius. It can be understood that the first magnet 221 and the second magnet 222 are used to drive the mahjong tiles in the shuffle turntable to flip, and the shuffle turntable rotates along its rotation axis, and the centroids of the first magnet 221 and the second magnet 222 are located on an arc with the same preset radius, so that the mahjong tiles on the shuffle turntable can pass through the approximately same magnetic field position of the first magnet 221 and the second magnet 222, so that they are more evenly affected by the magnetic field force. In one embodiment, the preset radius is the distance from the mahjong tiles on the shuffle turntable to the rotation axis of the shuffle turntable, so that the mahjong tiles on the shuffle turntable all pass through the center of the magnetic field of the first magnet 221 and the second magnet 222, thereby improving the efficiency of flipping the tiles.

[0031] like Figure 2 As shown, in one embodiment, the first mounting groove 2111 is connected to the second mounting groove 212. It can be understood that the first mounting groove 2111 is connected to the second mounting groove 212, so that the magnetic field of the first magnet 221 installed in the first mounting groove 2111 can be connected to the magnetic field of the second magnet 222 installed in the second mounting groove 212, thereby avoiding the magnetic field gap while increasing the effective area of ​​the magnetic field, and avoiding the dead angle when the mahjong tiles are flipped. The side wall of the first mounting groove 2111 away from the second mounting groove 212 and the side wall of the second mounting groove 212 away from the first mounting groove 2111 can be parallel to each other or not parallel to each other, as long as the first magnet 221 installed in the first mounting groove 2111 and the second magnet 222 installed in the second mounting groove 212 can be abutted against each other without relative displacement.

[0032] like Figure 3 As shown, in one embodiment, the second magnet 222 is provided with an avoidance cut angle for avoiding the first magnet 221. It can be understood that the centroids of the first magnet 221 and the second magnet 222 are located on the same arc of a preset radius, and the first mounting groove 2111 and the second mounting groove 212 are connected to each other, then the side wall of the first mounting groove 2111 away from the second mounting groove 212 and the side wall of the second mounting groove 212 away from the first mounting groove 2111 may not be parallel to each other, and therefore, there is an overlapping portion between the first magnet 221 and the second magnet 222. In this embodiment, the avoidance cut angle for avoiding the first magnet 221 is provided on the second magnet 222, so that the interference between the first magnet 221 and the second magnet 222 can be avoided on the basis of making the centroids of the first magnet 221 and the second magnet 222 located on the same arc of a preset radius.

[0033] like Figure 1 As shown, in one embodiment, the card flipping mechanism further includes a first rotating wheel 230 and a second rotating wheel 240 for placing a shuffle wheel; a first bracket 213 for mounting the first rotating wheel 230 is provided on the side of the first mounting slot 2111 away from the second mounting slot 212 of the mounting frame 210; a second bracket 214 for mounting the second rotating wheel 240 is provided on the side of the second mounting slot 212 away from the first mounting slot 2111 of the mounting frame 210. It can be understood that the shuffle wheel is placed on the first rotating wheel 230 and the second rotating wheel 240, so that it can rotate more smoothly relative to the card flipping mechanism. The connection method of the first rotating wheel 230 and the first bracket 213 includes but is not limited to one or more of the methods such as snap connection, screw connection or pin connection, as long as the first rotating wheel 230 can be rotated on the first bracket 213. The connection method of the second rotating wheel 240 and the second bracket 214 includes but is not limited to one or more of the methods such as snap connection, screw connection or pin connection, as long as the second rotating wheel 240 can be rotated on the second bracket 214.

[0034] In one embodiment, the extension line of the rotation axis of the first rotating wheel 230 intersects with the rotation axis of the shuffle turntable. It can be understood that the shuffle turntable rotates along its rotation axis, and the extension line of the rotation axis of the first rotating wheel 230 intersects with the rotation axis of the shuffle turntable, then the rotation direction of the first rotating wheel 230 is the same as the tangent direction of the rotation of the shuffle turntable, thereby avoiding the sliding between the first rotating wheel 230 and the shuffle turntable, and reducing the friction between the first rotating wheel 230 and the shuffle turntable.

[0035] In one embodiment, the extension line of the rotation axis of the second rotating wheel 240 intersects with the rotation axis of the shuffle turntable. It can be understood that when the extension line of the rotation axis of the second rotating wheel 240 intersects with the rotation axis of the shuffle turntable, the rotation direction of the second rotating wheel 240 is the same as the tangent direction of the rotation of the shuffle turntable, thereby avoiding the sliding between the second rotating wheel 240 and the shuffle turntable and reducing the friction between the second rotating wheel 240 and the shuffle turntable.

[0036] In one embodiment, the side wall of the first mounting slot 2111 away from the second mounting slot 212 is parallel to the rotation axis of the first rotating wheel 230. It can be understood that the mahjong tiles on the shuffle wheel rotate with the shuffle wheel, and the side wall of the first mounting slot 2111 away from the second mounting slot 212 is parallel to the rotation axis of the first rotating wheel 230, so that the mahjong tiles are subjected to a more uniform magnetic field force when passing through the magnetic field generated by the first magnet 221 installed in the first mounting slot 2111, thereby improving the efficiency of flipping the tiles.

[0037] In one embodiment, the side wall of the second mounting slot 212 away from the first mounting slot 2111 is parallel to the rotation axis of the second rotating wheel 240. It can be understood that the mahjong tiles on the shuffle wheel rotate with the shuffle wheel, and the side wall of the second mounting slot 212 away from the first mounting slot 2111 is parallel to the rotation axis of the second rotating wheel 240, so that the mahjong tiles are subjected to a more uniform magnetic field force when passing through the magnetic field generated by the second magnet 222 installed in the second mounting slot 212, thereby improving the efficiency of flipping the tiles.

[0038] like Figure 2 As shown, in one embodiment, the mounting frame 210 is provided with a structural hole 216. It is understandable that the shape of the structural hole 216 can be set according to actual conditions, as long as the material usage can be saved on the basis of ensuring the structural strength of the mounting frame 210.

[0039] like Figure 3 As shown, in one embodiment, a through hole 223 for avoiding the installation bolts of the electric box is provided on the second magnet 222. It can be understood that an electric box is provided on the side of the connection plate 100 of the mahjong machine away from the flipping mechanism, and the electric box needs to be screwed to the connection plate 100 by the electric box installation bolts, and the second magnet 222 blocks the position of the electric box installation bolts. Therefore, a through hole 223 for avoiding the installation bolts of the electric box is provided on the second magnet 222, thereby avoiding the influence on the installation of the electric box.

[0040] like Figure 1 As shown, in one embodiment, the card flipping mechanism further includes a connecting member 250; a connecting hole 215 is provided on the mounting frame 210; the connecting member 250 enables the mounting frame 210 to be mounted on the connecting plate 100 of the mahjong machine through the connecting hole 215. It can be understood that the connecting member 250 can be a bolt, and the connecting hole 215 can be a screw hole corresponding to the bolt, and the bolt is installed in the screw hole to enable the mounting frame 210 to be mounted on the connecting plate 100 of the mahjong machine.

[0041] like Figure 1 As shown, an embodiment of the utility model further provides a mahjong machine, and the mahjong machine includes the card turning mechanism.

[0042] In the mahjong machine of the utility model, a mounting frame 210 is arranged on the connecting plate 100 of the mahjong machine, and a first mounting groove 2111 for clamping the first magnet 221 and a second mounting groove 212 for clamping the second magnet 222 are arranged on the mounting frame 210, so that relative displacement between the first magnet 221 and the second magnet 222 due to the repulsive force is avoided, and at the same time, the effective area of ​​the magnetic field through the magnetic flipping is increased by the first magnet 221 and the second magnet 222, thereby improving the flipping efficiency of the mahjong machine.

[0043] The above are only embodiments of the card flipping mechanism and mahjong machine of the present invention, and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
