Description

Technical Field

[0001] This utility model discloses a fastening type of mahjong tile, belonging to the technical field of chess and card game supplies. Background Technology

[0002] Mahjong is a four-player tile game originating in China and popular in Chinese cultural spheres. It typically consists of small rectangular tiles made of bamboo, bone, or plastic, engraved with patterns or characters. Mahjong has a complex and diverse set of rules; the basic gameplay is simple and easy to learn, yet the variations are numerous, and the combinations vary from person to person, making it one of the most captivating forms of gambling in Chinese history.

[0003] Traditional mahjong tile manufacturing typically involves two methods: one where the tile is formed as a single piece, and the other where it is made in two parts: the face and the back. Existing mahjong tiles, where the face and back are made separately, are usually created by creating a groove on the face and a protrusion on the back to fit into the groove, then securing them with adhesive. However, because this is merely a simple grooving and gluing process, when the mahjong tile is subjected to a significant impact, such as being dropped, cracks easily form between the two parts, eventually causing them to separate at the glued joint, resulting in poor fastening. Therefore, to address this problem, this invention proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to provide a fastening type of mahjong tile to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a fastening type mahjong tile, including a tile face and a tile bottom, wherein a groove is provided at the bottom of the tile face, and a protrusion is provided at the top of the tile bottom to cooperate with the groove; a trapezoidal stabilizing protrusion is provided in the groove, the trapezoidal stabilizing protrusion is evenly arranged around the side wall of the groove, and a strip-shaped stabilizing reinforcing protrusion is provided in the groove, the strip-shaped stabilizing reinforcing protrusion being provided on both sides of the trapezoidal stabilizing protrusion.

[0006] Preferably, the strip-shaped stabilizing and reinforcing protrusion is configured as a semi-circular columnar protrusion, and each corner of the groove is provided with a chamfer.

[0007] Preferably, the groove is provided with an installation slot, the installation slot is provided with a counterweight, and the opening edge of the installation slot is provided with a positioning protrusion.

[0008] Preferably, the bottom of the card face is provided with a stabilizing and reinforcing floating edge, and the bottom of the card is provided with a stabilizing and reinforcing groove that cooperates with the stabilizing and reinforcing floating edge.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] By setting trapezoidal stabilizing protrusions and strip-shaped stabilizing and reinforcing protrusions in the grooves of the mahjong tiles, the contact area between the grooves and the protrusions is increased, thereby increasing static friction and improving the stabilizing effect. It also disperses the internal stress of the mahjong tiles when they are subjected to force, thus avoiding cracking caused by excessive stress concentration and achieving a firming effect.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] A type of secure mahjong tile, such as Figure 1 , Figure 2 , Figure 3 As shown, the mahjong tile includes a face tile 1 and a base tile 2. The bottom of the face tile 1 has a groove 3, and the top of the base tile 2 has a protrusion 4 that matches the groove 3. The base tile 2 can be directly injection molded after the face tile 1 is placed into the mold, so that the base tile 2 is directly formed on the bottom of the face tile 1, thereby achieving a better fastening effect. The groove 3 can be set as a rectangular groove with the same length and width ratio as the face tile 1, and each corner of the groove 3 is provided with a chamfer. The chamfer can reduce the stress concentration generated at the corner of the groove 3, thus reducing the probability of the mahjong tile breaking after being impacted.

[0017] The groove 3 is also provided with trapezoidal stabilizing protrusions 5. The trapezoidal stabilizing protrusions 5 are evenly arranged around the side wall of the groove 3, specifically four, distributed at the center of the four sides of the groove 3. The trapezoidal stabilizing protrusions 5 can increase the contact area between the groove 3 and the protrusion 4, thereby increasing the static friction and making the connection between the groove 3 and the protrusion 4 more stable. Moreover, the inward protrusion of the trapezoid can change and disperse the direction of force transmission between the groove 3 and the protrusion 4 when the mahjong tile is subjected to force to a certain extent, thereby reducing the probability of breakage caused by force concentration.

[0018] The groove 3 is provided with strip-shaped stabilizing and reinforcing protrusions 6. The strip-shaped stabilizing and reinforcing protrusions 6 are set as semi-circular columnar protrusions and are distributed on both sides of the trapezoidal stabilizing protrusions 5. The strip-shaped stabilizing and reinforcing protrusions 6 can further increase the friction area between the groove 3 and the protrusion 4, thereby further increasing the stability. In addition, its semi-circular columnar setting can also disperse the direction of force transmission and change the stress at the edge of the tile face 1 in the groove 3, thereby further reducing the probability of the mahjong tile breaking at the connection between the tile face 1 and the tile bottom 2.

[0019] The groove 3 is provided with an installation groove 7, and the installation groove 7 is provided with a counterweight 8. The opening edge of the installation groove 7 is provided with a positioning protrusion 9. The counterweight 8 can increase the weight of the mahjong tile, thereby improving the feel of the mahjong tile when playing. The bottom of the tile face 1 is provided with a stabilizing and reinforcing floating edge 10, and the tile base 2 is provided with a stabilizing and reinforcing groove that cooperates with the stabilizing and reinforcing floating edge 10. The stabilizing and reinforcing floating edge 10 and the stabilizing and reinforcing groove make the tile face 1 and the tile base 2 fit together, thereby further enhancing the fastening effect of the mahjong tile. When the connection between the tile face 1 and the tile base 2 is hit by a relatively sharp object, it is not easy to break directly.

[0020] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
