Description

Conversion plate for bottom plate of mahjong machine

Technical Field

The utility model relates to a mah-jong machine, in particular to a conversion plate for a bottom plate of the mah-jong machine.

Background

The bottom of the automatic mahjong machine is generally provided with a mahjong machine bottom plate, so that the upper machine body can be conveniently installed on the bottom supporting structure through the bottom plate.

The applicant has a Chinese patent document with an authorization notice number of CN207253738U, an authorization notice date of 2018, 20.04.2018 and a name of 'a full-automatic mahjong machine', wherein a mahjong machine bottom plate is disclosed and named as a generation bottom plate 9, and the specific structure of the generation bottom plate 9 is shown in figure 7. Correspondingly, the corresponding full-automatic mahjong machine is named as a generation machine body.

Subsequently, the applicant successively applied chinese patents with application publication numbers CN107596680A, application publication date of 2018, 01 and 19, entitled automatic mahjong machine of slope mahjong-out type, and chinese patents with application publication numbers CN108176043A, application publication date of 2018, 06 and 19, entitled automatic mahjong machine of slope mahjong-out type. Because the two slope tile discharging type automatic mahjong machines change the tile discharging mode, the mahjong tiles are more stable in the tile shuffling process. Meanwhile, the size of the mahjong machine bottom plate is greatly reduced, so that a second generation bottom plate 10 is formed, and the specific structure of the second generation bottom plate 10 is shown in figure 8. Correspondingly, the corresponding slope mahjong-discharging type automatic mahjong machine is named as a second-generation machine body.

Since some customers want to have a larger space for playing mahjong while needing stable shuffling, the upper structure of the second generation body needs to be mounted on the first generation base plate 9. However, the first generation chassis 9 is molded and manufactured according to the upper structure of the first generation body, which is not adapted to the upper structure of the second generation body. If the production of the mahjong machine needs to be carried out, the second generation base plate 10 needs to be secondarily designed, so that the size of the second generation base plate is enlarged, the second generation base plate is matched with the upper structure of the second generation machine body, the second generation base plate can have the same operation space with the first generation base plate 9, and a mahjong table which is stable in playing and large in area is formed. However, huge capital is required for opening the mold of the mahjong machine bottom plate, and particularly, the cost for opening the mold of the mahjong machine bottom plate is correspondingly increased under the condition that the area of the mahjong machine bottom plate is large, which is not beneficial to commercial production.

Based on the current situation, the applicant invents a conversion plate on the basis of the existing first generation bottom plate 9 and second generation bottom plate 10, so that the upper structure of the second generation machine body can be installed on the first generation bottom plate 9, and the die sinking of a new mahjong machine bottom plate is avoided.
