[0034] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail with reference to the embodiments.
[0035] Example 1
[0036] The double-layer mahjong machine base plate includes a first base plate 1, which is a metal plate. In this embodiment, the first base plate 1 is formed by stamping iron plate. The first base plate 1 has a downwardly recessed mounting groove 11. A second base plate 2, also made of metal plate and formed by stamping iron plate, is installed in the mounting groove 11 for mounting mahjong machine accessories. The second base plate 2 has multiple welding holes 21, distributed in four directions with five holes in each direction. The welding holes 21 penetrate the second base plate 2. The second base plate 2 is welded to the first base plate 1 through the welding holes 21, ensuring a secure connection that prevents easy separation.
[0037] The second base plate 2 has upwardly extending side portions 22 around its four edges. The side portions 22 are bent portions and fit against the side wall of the mounting groove 11. The side portions 22 are welded to the first base plate 1 to further strengthen the connection between the second base plate 2 and the first base plate 1, ensuring that the second base plate 2 can fit tightly against the first base plate 1.
[0038] The first base plate 1 has four corners with tabletops 12 for installing accessories. The tabletops 12 are triangular in shape. The side portions 22 are lower than the tabletops 12 and are not obtrusive, which facilitates welding them to the first base plate 1.
[0039] The second base plate 2 has a plurality of stamping grooves 23. The bottom of the mounting groove 11 has a plurality of first grooves 13 that mate with the stamping grooves 23. In this embodiment, each first groove 13 corresponds to 5 stamping grooves 23. The stamping grooves 23 form a boss on the back of the second base plate 2 and contact the bottom of the first grooves 13. The first grooves 13 serve to increase the bending strength of the end face of the first base plate 1 and to mate with the stamping grooves 23, so that the boss of the second base plate 2 is hidden in the first grooves 13. The lower end face of the second base plate 2 can be tightly attached to the bottom surface of the mounting groove 11, which facilitates welding the second base plate 2 to the bottom surface of the first grooves 13.
[0040] The welding hole 21 is located at the bottom of the stamping groove 23 and extends through the second base plate 2. The stamping groove 23 forms a boss on the back of the second base plate 2 and welds it to the bottom of the first groove 13 through the welding hole 21. The stamping groove 23 facilitates the operator to quickly locate the welding hole 21, and the solder after welding is hidden inside the stamping groove 23 and will not protrude from the end face of the second base plate 2. On the other hand, the boss formed by the stamping groove 23 on the back of the second base plate 2 will improve the bending strength of the second base plate 2.
[0041] The sidewall of the stamping groove 23 is a conical surface.
[0042] The bottom of the mounting groove 11 is provided with a second groove 14 in the shape of a four-pointed star, and the four corners of the second groove 14 extend toward the four corners of the first base plate 1 respectively. The second groove 14 is recessed downward and forms a convex ridge on the back of the first base plate 1. A first groove 13 is provided between each adjacent corner of the second groove 14. The first groove 13 and the second groove 14 are connected to form a single piece, thereby making the bending strength of the first base plate 1 stronger.
[0043] Example 2
[0044] Example 2 is basically the same as Example 1, except that a corner protector 3 is fixed at the corner of the lower end face of the first base plate 1. The side of the corner protector 3 is bent and wrapped around the outer side wall of the first base plate 1. The corner protector 3 serves two purposes: firstly, to protect the corner of the first base plate 1 and increase its strength; secondly, it facilitates the fastening of other accessories to the first base plate 1.
[0045] Example 3
[0046] The mahjong machine includes a support leg 4 and a connecting frame 5, with the connecting frame 5 fixed to the upper end of the support leg 4; it also includes the double-layer mahjong machine base plate in embodiment 2, with the support leg 4 fixed to the corner guard plate 3 via the connecting frame 5.
[0047] Support columns 6 are installed at the corners of the first base plate 1. The support columns 6 are installed on the table surface 12 of the first base plate 1, and the mahjong machine panel 7 is installed on the support columns 6.
