Description

Mahjong machine and folding mechanism thereof

Technical Field

The utility model belongs to the technical field of mahjong machine manufacturing, and particularly relates to a mahjong machine and a folding mechanism thereof.

Background

In order to facilitate transportation and save storage space when the mahjong machine is not in use, a tabletop main body provided with a mahjong machine core is usually hinged to the top end of the upright post, and the tabletop main body is folded along the hinge position during transportation or storage, so that the bottom of the tabletop main body is attached to one side of the upright post, and the purposes of convenience and space saving during transportation and storage are achieved. In the prior art disclosed in patent documents with publication numbers CN 105435448B, CN204798817U, CN211298857U, CN217285108U and TWM448195U, in these structures, the bottom of the table top main body and one side of the top end of the upright post are hinged through a fixed rotating shaft, which requires that half the width of the table top of the mahjong machine is smaller than the height of the upright post to realize turnover folding.

However, in the prior art, because of space requirements such as tile placement and the like in the mahjong playing process, the tabletop of the mahjong machine is large in size, and often half width of the tabletop is larger than the height of the upright post, so that overturning and folding cannot be realized. In order to solve the problem, if the height of the upright post is increased, the whole height of the table top of the mahjong machine is increased, and the comfort of use is affected; if the stand column is controlled to lift by the independent driving motor, the manufacturing cost is too high. In addition, because the tabletop main body of the mahjong machine is heavy, the gravity center of the whole mahjong machine deflects towards the folding side in the overturning process and in the folding state, the stability is poor, the mahjong machine is very easy to topple towards the folding side of the tabletop main body, and the mahjong machine is usually placed against a wall.
