Description

Technical Field

[0001] The utility model relates to a mahjong tile which can be used in an automatic mahjong machine. Background Art

[0002] Mahjong is a tabletop game originated from China. It is an entertainment activity that combines strategy, memory, calculation and probability. It has become a way for people to relax, entertain and interact socially. It is widely popular in Chinese communities around the world. Most of the mahjong tiles on the market are pressed from melamine. There will be a lot of dust in the production process. The internal filling is solid, and the production cost is high. The produced mahjong is hard and brittle. The collision and friction between mahjong tiles during shuffling will make a lot of noise, especially at night. It is very disturbing. When mahjong tiles fall to the ground, they not only make a loud noise but also break easily. In addition, mahjong tiles made of melamine are easy to crack when used in the north.

[0003] In addition, the cover plate and main shell of mahjong tiles are generally made of two pieces, a joint seam will be formed on the outer surface after jointing. The uneven joint seam will affect the feel, so grinding, polishing and other processes are required during the processing, which is complicated and difficult to process. Utility Model Content

[0031] (Example 1)

[0032] See Figure 1-4 The mahjong tiles that can be used for the automatic mahjong machine of this embodiment include a cover plate 1, a partition plate 2, a magnet, a counterweight and a main shell 3. The main shell 3 is a cavity 3-1 with an opening on one side. The cover plate 1 matches the opening surface of the cavity 3-1. The opening edge of the cavity 3-1 extends toward the cover plate 1 and is at least flush with the cover plate 1, that is, the cover plate 1 is embedded in the opening of the cavity 3-1. The side of the cover plate 1 facing away from the cavity 3-1 is provided with mahjong tile suits. The partition plate 2, the magnet and the counterweight are all arranged in the cavity 3-1; the partition plate 2 is located at the opening end of the cavity 3-1, and the magnet is in close contact with the cover plate 1.

[0033] Specifically, the cover plate 1, the partition plate 2 and the main shell 3 are made of plastic injection molding, and materials such as polypropylene, ABS, PC, etc. can be selected. There is no dust pollution in the production process, the formed mahjong tiles have low noise when used, and will not crack when used in northern regions.

[0034] The main housing 3 is in the shape of a rectangular parallelepiped, and has a cavity 3-1 with one side open. A circle of steps 3-2 is arranged along the inner wall at the opening, and the cover plate 1 is embedded in the opening of the cavity 3-1 and matched with the step 3-2. Since the cover plate 1 is embedded in the main housing 3, no joint seam is formed on the outer surface of the main housing 3, which has a better hand feel and reduces the production and processing procedures.

[0035] The side of the cover plate 1 facing away from the cavity 3-1 is provided with mahjong tiles, which can be printed and drawn by UV printing technology. A layer of varnish is wrapped on the surface of the tiles, which increases the brightness and artistic effect of the tiles and protects the surface of the tiles. The tiles have good wear resistance, high hardness, and are not prone to scratches, which prolongs the overall life of the tiles.

[0036] Because the mahjong tiles of this embodiment are used in an automatic mahjong machine, the card suction wheel absorbs the mahjong tiles during the shuffling process, and then transfers the mahjong tiles to the card coding area, with the side of the coded tiles facing downward. Therefore, the magnet needs to be set on the side of the main shell cavity 3-1 close to the cover plate 1 to ensure that the card suction wheel absorbs the mahjong tiles on the side with the color, that is, the side of the cover plate 1. For this reason, a partition plate 2 is provided in this embodiment. The partition plate 2 is provided with a groove 2-2 with an opening facing the cover plate 1, and the magnet is embedded in the groove 2-2. A plurality of supporting parts 3-3 are provided in the cavity 3-1 of the main shell 1, and the supporting parts 3-3 cooperate with the partition plate 2; the partition plate 2 is provided with a through hole 2-1, and the cover plate 1 is provided with a fixing rod 1-1 on the side facing the cavity 3-1, and the fixing rod 1-1 cooperates with the through hole 2-1. After assembly, the partition plate 2 and the magnet are both tightly attached to the cover plate 1.

[0037] The rest of the main housing cavity 3-1 is filled with weights to balance the feel of the mahjong tiles. The weights are preferably made of low-priced materials to save costs, and the weights must not interfere with the magnetic field of the magnets and affect the shuffling function. In this embodiment, the weights are made of quartz sand, which is hard, wear-resistant and has stable chemical properties.

[0038] During assembly, first fill the counterweight into the main shell cavity 3-1, then embed the partition plate 2 into the opening of the main shell cavity 3-1, so that the partition plate 2 is placed on the support portion 3-3, then embed the magnet into the groove 2-2 of the partition plate 2, and finally embed the cover plate 1 into the opening of the cavity 3-1 of the main shell 3. After assembly, the partition plate 2 is tightly attached to the cover plate 1, and the magnet is tightly attached to the cover plate 1. In addition, the partition plate 2 and the cover plate 1 can also be formed in one piece, as long as the magnet is finally attached to the cover plate 1 to ensure a good adsorption effect when shuffling. Finally, spray protective paint on the outer surface of the mahjong tiles to form a protective layer. The protective layer can cover the edge formed after the cover plate 1 is embedded in the main shell 3, so that the appearance and feel of the mahjong tiles are better, and the sense of unity is stronger.

[0039] (Example 2)

[0040] This embodiment is not shown in the figure. The surface of the main housing 3 opposite to the cover plate 1 is called the bottom surface. The mahjong tiles are arranged on the outer side of the bottom surface. In order to make the card suction wheel absorb the mahjong tiles better during the shuffling process, the magnet is arranged on the side close to the bottom surface in the main housing 3. The cover plate 1 is provided with a plurality of limit rods facing the bottom surface to press the magnet against the bottom surface. At the same time, a plurality of support parts 3-3 are arranged in the cavity 3-1 of the main housing 1 to limit the circumferential position of the magnet, so as to facilitate the fixing of the magnet. The remaining empty part in the cavity 3-1 of the main housing 1 is filled with a counterweight.

[0041] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
