Balanced type electric and manual universal mahjong machine foldable base

Abstract

The invention discloses a balance type electric and manual universal mahjong machine foldable base. The foldable base comprises a bottom plate, a stand column, a top plate and a transmission mechanism, the transmission mechanism is arranged in an inner cavity of the stand column and used for driving the top plate to rotate and driving the stand column to laterally move, the stand column is in sliding fit with the bottom plate, the bottom plate comprises a bottom frame, a cross beam fixed in an inner cavity of the bottom frame and two guide rails, and the top plate comprises a face plate and a first connecting block. According to the balance type electric and manual universal mahjong machine foldable base, balance of the gravity center of a mahjong table is achieved through overturning of amahjong table and translation of the stand column. Compared with traditional mahjong machines which cannot be folded, the mahjong machine has the advantages that the face plate can be folded, the purpose of reducing space is achieved, and storage is more convenient; and compared with existing foldable mahjong machines, the mahjong machine of the invention has the advantages that the gravity center is close to the center of the bottom plate after the face plate is folded, the balance is better, the electric mode and the manual mode can be switched mutually, the structure is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of automatic mahjong machine equipment, in particular to a foldable base of a balanced electric manual universal mahjong machine. Background technique [0002] After decades of development, the fully automatic mahjong machine has become one of the entertainment tools of the family society. Because the mahjong machine generally has a large desktop and is not easy to store, foldable mahjong machines have gradually appeared on the market. The table top of the mahjong machine is folded with the column supporting the mahjong machine, so as to reduce the space occupied by the table top of the mahjong machine and improve the utilization rate of space. [0003] Most of the foldable bases of the mahjong machine that exist in the prior art can only complete the function of erecting the desktop of the mahjong machine by arranging structures on the mahjong machine base, but such erection can reduce the size of the mahjo...

AI Technical Summary

Problems solved by technology

[0003] Most of the foldable bases of the mahjong machine that exist in the prior art can only complete the function of erecting the desktop of the mahjong machine by arranging structures on the mahjong machine base, but such erection can reduce the size of the mahjong machine desktop. The area of ​​the mahjong machine is limited, and the space utilization rate cannot be really improved. After the tabletop is erected, the positions of the base and the column used to support the tabletop remain unchanged, which causes the center of gravity of the mahjong machine to shift from the center line to the rotation direction of the tabletop. On the other hand, since the base of the traditional mahjong machine is usually small, the offset of the center of gravity of the mahjong machine will directly affect the stability of the desktop after it is erected, making the mahjong machine very easy to fall to one side of the direction of the center of gravity.

[0004] At the same time, the foldable base of the existing folding mahjong machine also has the following problems: the production cost is high due to the complex structure, but the realized function is poor, and the installation and maintenance are relatively troublesome; the pure electric or pure manual type is inconvenient in actual use. When the motor fails, the pure electric type often hangs the desktop in mid-air state and cannot be lifted and maintained, and the pure manual type cannot achieve balance and stability when in use; it is difficult to refit each other with pure electric type or pure manual type, so the usable range is not enough. widely
