The four corners of the upper surface of the base plate are provided with L-shaped first connecting members. The upper end of the first connecting member is fixed to the panel, and the lower end is fixed to the base plate. The support frame includes a support foot and a second connecting member fixedly arranged on the upper part of the support foot. The second connecting member includes two second connecting parts, and the two second connecting parts are arranged at right angles. The two second connecting parts each extend inwardly to form a load-bearing member portion. The load-bearing member portion is provided with a plurality of first through-holes. The base plate is placed on the load-bearing member portion. Bolts pass through the first through-holes to fix the base plate and the load-bearing member portion. The load-bearing member portion is also provided with a plurality of mounting holes for convenient bolting of the base plate and the first connecting member. The support foot includes a support foot body and a cover plate provided on the upper end of the support foot body. The upper end of the support foot is provided with a mounting opening.

[0003] In the prior art, the base plate is mounted on the supporting legs via load-bearing members, which only support the edge of the base plate. However, since the main body of the mahjong machine is mounted on the base plate, the base plate has a large weight, and the load-bearing members need to withstand a large pressure, which makes the load-bearing members prone to deformation. Moreover, the base plate of the mahjong machine is formed by metal stamping. Therefore, since the supporting surface of the load-bearing members is small, the probability of deformation of the base plate is high after the mahjong machine is assembled. Utility Model Content

Example

[0039] like Figure 1-11 The mahjong machine frame shown includes a base plate 1 and multiple support assemblies for supporting the base plate 1. The base plate 1 includes a first planar portion 11, a second planar portion 13 is provided at the center of the first planar portion 11 and is recessed downward. The first planar portion 11 and the second planar portion 13 are connected by a transition portion 14. The support assembly includes a support leg 2, a load-bearing member 3, and a support member 7. The load-bearing member 3 and the support member 7 are both fixed to the support leg 2, and the load-bearing member 3 is located above the support member 7.

[0040] The bottom plate 1 is fixed on the load-bearing member 3 and the support member 7 , a corner of the first plane portion 11 is fixedly connected to the load-bearing member 3 , and the second plane portion 13 is fixedly connected to the support member 7 .

[0041] With such arrangement, in the above scheme, the weight of the base plate 1 is diverted to different positions of the support leg 2 by the load-bearing member 3 and the support member 7, and the load-bearing member 3 is connected to the support part, which can further improve the stability, load-bearing upper limit and carrying capacity of the support assembly; in the above scheme, after the load-bearing member 3 is installed on the base plate 1, the load-bearing member 3 and the base plate 1 are installed on the support leg 2 together, so that when the support leg 2 and the base plate 1 are fixed, the load-bearing member 3 can be automatically locked in the installation opening 21 of the support leg 2, thereby reducing the positioning accuracy of each component, reducing the difficulty of frame assembly, and improving the efficiency of frame assembly and maintenance; in the above scheme, the load-bearing member 3 is not directly fixed on the support leg 2, which makes the structure of the support leg 2 simpler, and makes it easy to make each part of the frame separately, and to store and transport the parts.

[0042] In this embodiment, the load-bearing member 3 includes a receiving portion 32, and two first abutting portions 31 are provided above the receiving portion 32. The two first abutting portions 31 are provided at an angle, and a corner of the bottom plate 1 is inserted between the two first abutting portions 31. The edge of the bottom plate 1 abuts against the first abutting portions 31, and a corner of the first planar portion 11 is pressed against the receiving portion 32 of the load-bearing member 3. The bottom plate 1 and the receiving portion 32 are fixedly connected. Figure 9As shown, on the load-bearing member 3 , the edge of the receiving portion 32 is bent upward to form a first abutting portion 31 ; the angle between the two first abutting portions 31 is 90°.

[0043] In this embodiment, the load-bearing member 3 includes a receiving portion 32, which is provided with a downwardly protruding second abutting portion 33. The second abutting portion 33 presses against the support member 7. Furthermore, the top of the second abutting portion 33 is concave, and the first planar portion 11 of the base plate 1 is provided with a downwardly protruding first reinforcing portion 16. After the base plate 1 and the load-bearing member 3 are fixed, the first reinforcing portion 16 of the base plate 1 presses down from above against the second abutting portion 33 of the load-bearing member 3. This arrangement can enhance the strength of the base plate itself and also support the base plate from various heights.

[0044] In this embodiment, a mounting opening 21 is provided on the support leg 2, into which both the load-bearing member 3 and the base plate 1 are inserted.

Specifically, the first support portion 71 abuts against the first reinforcement portion; the end surface of the second support portion 72 matches the transition portion 14 of the base plate 1. After the support member 7 is fixed to the base plate 1, the second support portion 72 abuts against the transition portion 14 of the base plate 1. The transition portion 14 and the second support portion 72 are both arc-shaped. This arrangement can increase the support position and support area between the base plate 1 and the support member 7, further improving the load-bearing capacity of the rack.

[0046] In this embodiment, Figure 5 and Figure 8 As shown, the support member 7 is provided with a raised first connecting portion 73, which is provided with a through hole 74. After the first connecting portion 73 extends below the second planar portion 13 of the base plate 1, a bolt 6 is threadedly connected to the base plate 1 through the through hole 74. This arrangement can further increase the connection area between the support member 7 and the base plate 1 and improve the positioning accuracy of various parts after the rack is assembled.

[0047] In this embodiment, Figures 4 to 7 As shown, a second reinforcing portion 15 protruding downward is provided on the second planar portion 13 of the base plate 1 , and the first connecting portion 73 is located below the second reinforcing portion 15 and is fixedly connected by bolts 6 .
