Description

Technical Field

[0001] The utility model belongs to the field of mahjong machines and relates to a small bowl fixing structure of a mahjong machine. Background Art

[0002] In the existing mahjong machine, the small bowl 2 on the operating panel is installed on the lifting tube 1, and two fixing screws 5 at right angles to each other are screwed into the lifting tube. This fixing method causes the small bowl to be stressed on one side, which is uneven and easy to shake, and has poor stability. Summary of the invention

[0003] In order to overcome the shortcomings of unevenness and poor stability of the small bowl of the mahjong machine in the prior art, the utility model provides a small bowl fixing structure for the mahjong machine with improved stability.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A small tray bowl fixing structure for a mahjong machine comprises a lifting tube and a small tray bowl, wherein the small tray bowl is sleeved on the end of the lifting tube, and is characterized in that the lifting tube is provided with opposing holes near the top, and the line connecting the centers of the two opposing holes is located on the diameter of the inner cavity of the lifting tube, and the fixing structure also comprises a long screw rod and a fixing nut, and mounting holes for the long screw rod to pass through are provided on both sides of the bottom of the small tray bowl, and the mounting holes cooperate with the opposing holes, and the long screw rod is locked and fixedly connected by the fixing nut after passing through the mounting hole and the opposing hole.

[0006] The solution of the utility model is to design a long screw rod through which the bottom of the small supporting bowl and the lifting tube are penetrated, and the screw rod is locked and fixed with a fixing nut, so that the small supporting bowl is evenly stressed, does not shake, has a smoother surface, and improves stability.

[0007] The beneficial effects of the utility model are mainly manifested in: improving stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The utility model is a schematic diagram of the small bowl fixing structure of the existing mahjong machine.

[0009] Figure 2 It is a three-dimensional diagram of the small bowl fixing structure of the mahjong machine of the utility model.

[0010] Figure 3 It is a cross-sectional view of the small bowl fixing structure of the mahjong machine of the utility model.

[0011] Figure 4 It is a top view of the small bowl fixing structure of the mahjong machine of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] Reference Figure 2 to Figure 4 A small bowl fixing structure for a mahjong machine comprises a lifting tube 1 and a small bowl 2, wherein the small bowl 2 is sleeved on the end of the lifting tube 1, and the lifting tube 1 is provided with a facing hole near the top, and the connecting line of the centers of the two facing holes is located on the diameter of the inner cavity of the lifting tube. The fixing structure also comprises a long screw rod 3 and a fixing nut 4, and mounting holes for the long screw rod 3 to pass through are provided on both sides of the bottom of the small bowl 2, and the mounting holes cooperate with the facing holes, and the long screw rod 3 is locked and fixedly connected by the fixing nut 4 after passing through the mounting hole and the facing hole.

[0014] The solution of this embodiment is to design a long screw rod 3 to penetrate the bottom of the small bowl 2 and the lifting tube 1, and lock and fix it with a fixing nut 4; so that the small bowl 2 is evenly stressed, does not shake, has a flatter surface, and improves stability.

[0015] The contents described in the embodiments of this specification are merely enumerations of implementation forms of the utility model concept and are for illustrative purposes only. The protection scope of the utility model should not be considered to be limited to the specific forms described in this embodiment, and the protection scope of the utility model also extends to equivalent technical means that ordinary technicians in this field can think of based on the concept of the utility model.

Claims
