Description

Technical Field

[0001] The utility model belongs to a mahjong machine, and relates to a leveling structure for a pushing and lifting component of a mahjong machine. Background Art

[0002] For the existing mahjong machines, the main methods for leveling the card-lifting plate and the mahjong machine panel are to pad some open gaskets under the card-lifting plate or some non-drying adhesive films under the panel to adjust the flatness of the two. For the leveling method of padding some open gaskets under the card-lifting plate, the screws need to be loosened and tightened repeatedly during the leveling process; for the leveling method of padding some non-drying adhesive films under the panel, the panel and the card-lifting strip need to be taken out repeatedly during the leveling process. The technical defects of the existing leveling methods are: the process is cumbersome and the operation is time-consuming. Summary of the Invention

[0003] In order to overcome the deficiencies of the cumbersome process and time-consuming operation of the existing leveling method for the pushing and lifting component of a mahjong machine, the utility model provides a leveling structure for the pushing and lifting component of a mahjong machine with simplified operation and more convenient and rapid adjustment.

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

[0005] A leveling structure for a pushing and lifting component of a mahjong machine, comprising a pushing and lifting component connected to the card-lifting plate of the mahjong machine. The pushing and lifting component includes a pushing and lifting bottom foot, and the pushing and lifting bottom foot is connected to the bottom plate of the mahjong machine. It is characterized in that the leveling structure further includes an internal and external thread adjusting nut, a locknut and a fixing screw. The locknut is fixed on the bottom surface of the bottom plate of the mahjong machine. The internal and external thread adjusting nut passes through the mounting hole on the bottom plate of the mahjong machine. The external nut of the internal and external thread adjusting nut is threadedly connected with the locknut. The top platform of the internal and external thread adjusting nut abuts against the bottom surface of the pushing and lifting bottom foot. The fixing screw passes through the mounting hole of the pushing and lifting bottom foot and is threadedly connected with the internal thread of the internal and external thread adjusting nut.

[0006] Further, there are at least two sets of the internal and external thread adjusting nut, the locknut and the fixing screw, which are respectively arranged on the side of the pushing and lifting bottom foot. The number of the leveling components is set according to the situation. Each set of leveling components can be adjusted independently or simultaneously.

[0007] Furthermore, a connecting hole is provided in the middle of the pushing and lifting bottom foot, and a threaded hole is provided in the middle of the bottom plate of the mahjong machine. The pre-tightening bolt passes through the connecting hole and is fixed in the threaded hole. In this solution, the pre-tightening bolt adopts the existing technology and contains a spring, which can provide a pre-tightening force to elastically fix the pushing and lifting component.

[0008] Furthermore, a screwdriver through hole is opened on the mahjong machine panel or the card-lifting plate, and the screwdriver through hole is located directly above the fixing screw.

[0009] The beneficial effects of the present utility model are mainly manifested in: simplifying the operation and making the adjustment more convenient and rapid. Description of the Drawings

Detailed Embodiment

[0016] The present utility model will be further described below in conjunction with the drawings.

[0017] Referring to Figure 1 , a leveling structure of the lifting assembly of a mahjong machine, comprising a lifting assembly 3 connected to the card lifting plate of the mahjong machine, the lifting assembly 3 comprising a lifting bottom foot 31, the lifting bottom foot 31 being connected to the bottom plate 4 of the mahjong machine, the leveling structure further comprising an internal and external thread adjusting nut 5, a locknut 6 and a fixing screw 7, the locknut 6 being fixed to the bottom surface of the bottom plate 4 of the mahjong machine, the internal and external thread adjusting nut 5 passing through the mounting hole on the bottom plate 4 of the mahjong machine, the external nut of the internal and external thread adjusting nut 4 being threadedly connected to the locknut 6, the top platform of the internal and external thread adjusting nut 5 abutting against the bottom surface of the lifting bottom foot 31, and the fixing screw 7 passing through the mounting hole of the lifting bottom foot 31 and being threadedly connected to the internal thread of the internal and external thread adjusting nut 5.

[0018] Further, there are at least two sets of the internal and external thread adjusting nut 5, the locknut 6 and the fixing screw 7, which are respectively arranged on the side of the lifting bottom foot 31. The quantity of the leveling components is set according to the situation, and each set of leveling components can be adjusted independently or simultaneously.
