For easy storage and space saving, mahjong machines are usually equipped with a folding mechanism, allowing them to be unfolded when in use and folded away when not in use, reducing their footprint and facilitating transport and storage.

[0003] For example, Chinese Patent Publication No. CN217287152U discloses an automatic folding base and a mahjong machine. This utility model provides an automatic folding base and a mahjong machine. This utility model proposes an automatic folding base and a mahjong machine, including a base, a column mounted on the base, a U-shaped seat mounted on the column, and a panel mounted on the U-shaped seat; an automatic lifting rod is provided inside the column, and the automatic lifting rod is rotatably connected to the panel; the panel and the U-shaped seat are connected by a flip piece, and an arc-shaped track is provided on the flip piece, along which the panel flips.

[0004] Although the above-mentioned device realizes the folding function of the mahjong machine, in actual use, the panel will rotate and fold rapidly when the mahjong machine is folded, which is prone to impact. This not only easily damages the panel of the mahjong machine, but also easily causes the mahjong machine to tip over, resulting in damage to the mahjong machine and causing unnecessary losses. Utility Model Content

[0023] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0024] Example

[0025] Reference Figures 1 to 6 A mahjong machine folding structure with anti-tipping function includes a support component 1, a folding component 2 is provided on the upper surface of the support component 1, and two sets of folding components 2 are symmetrically arranged, with a mahjong machine panel 3 provided between the two sets of folding components 2.

[0026] The support assembly 1 includes a base 11, a frame seat 12 is rotatably connected to one side of the base 11, and casters 13 are provided on both the lower end of the base 11 and one side of the frame seat 12. There are two sets of casters 13 on one side of the frame seat 12 and four sets of casters 13 at the bottom of the base 11. The casters 13 facilitate the movement of the device.

[0027] The folding assembly 2 includes a support housing 21 fixedly connected to the upper end of the base 11. A U-shaped rotating plate 22 is connected to one side of the mahjong machine panel 3 by bolt thread. One corner of the support housing 21 is located inside the U-shaped rotating plate 22. A rotating shaft 23 is rotatably connected between one corner of the support housing 21 and the lower end of the U-shaped rotating plate 22. The support housing 21 and the U-shaped rotating plate 22 are rotatably connected by the rotating shaft 23.

[0028] A connecting shaft 24 is rotatably connected through both sides of the U-shaped rotating plate 22, and the connecting shaft 24 is positioned above the rotating shaft 23. A transmission bar 25 is rotatably connected to one end of the connecting shaft 24 extending out of the U-shaped rotating plate 22. One end of the transmission bar 25 is rotatably connected to one side of the frame seat 12. When the mahjong machine panel 3 rotates, causing the U-shaped rotating plate 22 to rotate, the frame seat 12 can also rotate through the transmission of the transmission bar 25.

[0029] The upper end of the support housing 21 is provided with a mounting groove 211, and a damping rod 27 is rotatably connected to the inner wall of the mounting groove 211. The upper end of the damping rod 27 is rotatably connected to the connecting shaft 24. A limit component 26 is provided inside the U-shaped rotating plate 22.

[0030] A torsion spring 29 is fixedly connected between one side of the mounting groove 211 and the inner wall of the U-shaped rotating plate 22, and the torsion spring 29 is wound around the outside of the rotating shaft 23.

[0031] The limiting component 26 includes an L-shaped fixing plate 261 fixedly connected to the inner side of the U-shaped rotating plate 22 and a rubber pad 262 fixedly connected to the inner side of the L-shaped fixing plate 261. The distance between the lower surface of the L-shaped fixing plate 261 and the lower surface of the U-shaped rotating plate 22 is the same as the length of the supporting housing 21. When the U-shaped rotating plate 22 rotates counterclockwise by 90 degrees, the L-shaped fixing plate 261 will contact one side of the supporting housing 21.

[0032] A triangular sleeve 28 is rotatably connected to one side of the support housing 21. The triangular sleeve 28 is used to fix the L-shaped fixing plate 261.

[0033] In this invention, when the mahjong machine panel 3 needs to be unfolded, an external force is applied to rotate the mahjong machine panel 3 counterclockwise by 90 degrees, so that the upper end of the support housing 21 is embedded inside the U-shaped rotating plate 22. At this time, the L-shaped fixing plate 261 contacts one side of the support housing 21. Then, the triangular sleeve 28 is rotated so that the triangular sleeve 28 is fitted onto the L-shaped fixing plate 261. At this time, the rubber pad 262 will be squeezed and deformed by the triangular sleeve 28, which can increase the friction between the triangular sleeve 28 and the rubber pad 262, reduce the possibility of the triangular sleeve 28 falling off, and the triangular sleeve 28 can be used to... The L-shaped fixing plate 261 is fixed in position, and the position of the mahjong machine panel 3 is fixed at this time. During the rotation of the mahjong machine panel 3, the frame base 12 will rotate to be horizontal with the base 11 through the push of the transmission bar 25. After the mahjong machine panel 3 is rotated to the horizontal, the overall center of gravity of the folding component 2 and the mahjong machine panel 3 will shift towards the frame base 12. At this time, the folding component 2 and the mahjong machine panel 3 are supported by the base 11 and the frame base 12 together, and the center of gravity is more inclined to the center of the base 11 and the frame base 12, which can improve stability and prevent the base 11 from tipping over.

[0034] When the folded mahjong machine panel 3 needs to be unfolded, an external force is applied to rotate the triangular sleeve 28, causing the triangular sleeve 28 to no longer fix the L-shaped fixing plate 261. Then, an external force is applied to rotate the mahjong machine panel 3 clockwise by 90 degrees, causing the mahjong machine panel 3 to be folded. During this process, the frame base 12 is pulled and folded by 90 degrees. After the mahjong machine panel 3 is folded, the overall center of gravity of the folding component 2 and the mahjong machine panel 3 will shift away from the frame base 12. At this time, the folding component 2 and the mahjong machine panel 3 are supported by the base 11, and the center of gravity is closer to the center of the base 11, which can improve stability and prevent tipping. This further improves the anti-tipping performance. During the rotation of the mahjong machine panel 3, the torsion spring 29 can convert some mechanical energy into elastic potential energy, reducing sudden impacts or vibrations. The damping rod 27 can dissipate energy, allowing the torsion spring 29 to stabilize quickly, which can further improve the anti-tipping effect of the device and reduce the possibility of damage to the mahjong machine panel 3.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
