Abstract
Description
Technical Field
[0001] This utility model relates to the field of mahjong tables, and more particularly to the base plate of a mahjong machine and the mahjong machine thereof. Background Technology
[0002] The base plate is an important component of a mahjong table. As the base, most of the accessories are installed on it, so the strength requirement of the base plate is quite important. The common practice is to weld multiple reinforcing ribs to the lower end of the base plate, or to stamp some grooves on the base plate to increase strength, such as the mahjong machine and its metal base plate with announcement number CN205759619U. However, the strength of a single base plate is still somewhat insufficient. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a mahjong machine base plate and a mahjong machine thereof.
[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:
[0005] The base plate of the mahjong machine includes a base plate with a downwardly recessed mounting groove on the upper surface of the base plate and a downwardly recessed first groove at the bottom of the mounting groove. The first groove is an annular groove, and a support plate is installed at the port of the first groove. The support plate is an annular support plate.
[0006] Preferably, the port of the first groove is provided with a stepped surface, and the edge of the support plate is placed on the stepped surface.
[0007] Preferably, the step surface has an upwardly arched boss, and the upper surface of the boss has a downwardly recessed second groove.
[0008] Preferably, the upper surface of the boss is flush with the upper surface of the support plate.
[0009] Preferably, the bottom of the mounting groove is provided with a number of inclined grooves, the bottom surface of which is an inclined surface, and all inclined grooves are connected to the first groove.
[0010] Preferably, all the inclined slots extend to one point and converge at one end.
[0011] Preferably, the vertical depth of the inclined groove is greater the closer it is to the end of the first groove.
[0012] Preferably, the support plate has a plurality of protrusions, each of which is adapted to a corresponding inclined groove, and the protrusions cover the port of the inclined groove.
[0013] Preferably, the support plate is provided with a plurality of clearance holes for avoidance.
[0014] Mahjong machine, including the base plate of the mahjong machine.
[0015] This utility model, by adopting the above technical solution, has significant technical effects:
[0016] The first groove of the base plate is designed in a ring shape, creating a ring-shaped protrusion on the back of the base plate, which increases the bending strength of the base plate. At the same time, a support plate is also installed on the first groove, further enhancing the bending strength of the base plate.
[0017] The base plate is also stamped with a number of inclined grooves and second grooves, which further increases the overall bending strength of the base plate. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.
[0026] Example 1
[0027] The mahjong machine base plate includes a metal base plate 1. In this embodiment, the base plate 1 is an iron plate. The upper surface of the base plate 1 has a downwardly recessed mounting groove 11, which is stamped and formed. The bottom of the mounting groove 11 has a downwardly recessed first groove 12, which is also stamped and formed. The first groove 12 is an annular groove, which improves the bending strength of the middle section of the base plate 1. A support plate 2 is installed at the end of the first groove 12. The support plate 2 is used to install some accessories of the mahjong machine, such as the large plate, which is mounted on the support plate 2 via roller seats. The support plate 2 is an annular support plate, welded to the base plate 1. In other embodiments, the support plate 2 can be fastened to the base plate 1 with bolts.
[0028] The first groove 12 has a stepped surface 13 at its port, which serves as a support and the edge of the support plate 2 is placed on the stepped surface 13.
[0029] The stepped surface 13 is provided with an upwardly arched boss 14. The upper end face of the boss 14 is provided with a downwardly recessed second groove 15. The second groove 15 is used to enhance the strength of the base plate 1. The boss 14 is formed by upward stamping. Although the boss 14 is used to install mahjong machine accessories, its design with the stepped surface 13 further increases the strength of the base plate 1.
[0030] The upper surface of the boss 14 is flush with the upper surface of the support plate 2, which facilitates the installation of mahjong machine accessories.
[0031] The bottom of the mounting groove 11 is provided with a number of inclined grooves 16. In this embodiment, there are 8 inclined grooves 16. The inclined grooves 16 are used to increase the strength of the base plate 1. The bottom surface of the inclined grooves 16 is an inclined surface. All inclined grooves 16 are connected to the first groove 12.
[0032] All the inclined grooves 16 extend to one point and converge at one end. Inclined grooves 16 are arranged in all directions of the base plate 1. The inclined grooves 16 cooperate with the first groove 12, which greatly improves the strength of the base plate 1.
[0033] The closer to the end of the first groove 12, the deeper the vertical depth of the inclined groove 16 becomes. The inclined groove 16 forms a ridge on the back of the base plate 1, which increases the thickness of the base plate 1. The design of the gradually deepening inclined groove 1 makes the base plate 1 not appear too thick when viewed from the side.
[0034] The support plate 2 is provided with a plurality of avoidance holes 22 for avoidance. In this embodiment, there are 8 avoidance holes 22. The avoidance holes 22 are circular and pass through the through holes of the support plate 2. The avoidance holes 22 are used to avoid the rollers of the large disc.
[0035] Example 2
[0036] Example 2 is basically the same as Example 1, except that the support plate 2 is provided with a number of protrusions 21. In this example, there are 8 protrusions 21, and each protrusion 21 is adapted to the corresponding inclined groove 16. The protrusion 21 covers the port of the inclined groove 16.
[0037] Example 3
[0038] A mahjong machine, including the mahjong machine base plate in embodiment 1 or 2.
