Description

Technical Field

[0001] This invention relates to the technical field of mahjong machines, and particularly to a folding base for a mahjong machine and a mahjong machine. Background Technology

[0002] Automatic mahjong machines typically consist of a main unit, a column, and a base, with the main unit supported on the base by the column. In existing technology, the main unit and column are usually fixedly connected, keeping the main unit in a horizontal position. Because the main unit cannot be adjusted relative to the base, automatic mahjong machines suffer from the following drawbacks during transportation, handling, and storage: they are large in size, occupy a lot of space, have high packaging costs, and are difficult to pass through narrow passages or fit into the trunk of a regular vehicle, causing considerable inconvenience for users.

[0003] To address the aforementioned issues, existing technologies have proposed a foldable automatic mahjong machine structure, replacing the fixed connection between the main unit and the upright with a hinged connection. This hinged structure allows the main unit to flip relative to the upright to a horizontal position during use and to flip to a vertical or tilted position when not in use, thus switching the entire machine from an unfolded to a folded form. This reduces packaging volume and storage space, improving the convenience of transportation and storage.

[0004] However, there is still room for improvement in the existing foldable mahjong machines, so it is necessary to make the base foldable to further reduce the space. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a folding base for a mahjong machine and a mahjong machine, which aims to solve the technical problem that mahjong machines are too large and difficult to transport in the prior art.

[0006] To achieve the above objectives, in a first aspect, the present invention proposes a folding base for a mahjong machine, comprising: a base, the base including a fixed seat and a flipping seat, wherein a flipping mechanism is provided between the flipping seat and the fixed seat; during the folding process, the side of the flipping seat away from the fixed seat slowly approaches the fixed seat, and the side of the flipping seat close to the fixed seat slowly rises, so that the flipping seat is tilted or perpendicular to the fixed seat. A column, which is mounted on a fixed base; The main unit is rotatably mounted on the column.

[0007] Preferably, a linkage mechanism is provided between the main unit and the base, so that when the main unit is flipped and folded, the flipping base is driven to flip and fold through the linkage mechanism.

[0008] Preferably, the linkage mechanism includes a first linkage assembly symmetrically arranged on the host, a first rotating shaft arranged between the two first linkage assemblies, a second linkage assembly arranged on the first rotating shaft, and a second rotating shaft arranged on the fixed base; the first rotating shaft is rotatably arranged on the column, and the second rotating shaft is rotatably arranged on the fixed base.

[0009] Preferably, the first linkage assembly includes a first straight rod and a second straight rod, one end of the first straight rod is rotatably disposed at the end of the second straight rod, and the other end of the second straight rod is fixed on the first rotating shaft.

[0010] Preferably, the second linkage assembly includes an L-shaped rod, a third straight rod, and a transmission mechanism; one end of the L-shaped rod is fixed on the first rotating shaft, and the other end is rotatably disposed on one end of the third straight rod, the other end of the third straight rod is disposed on the transmission mechanism, and the transmission mechanism is connected to the second rotating shaft.

[0011] Preferably, the transmission mechanism includes a fourth straight rod rotatably connected to the third straight rod, and the other end of the fourth straight rod is fixed on the second rotating shaft; Alternatively, the transmission mechanism may include a sector gear rotatably connected to the third straight rod, the sector gear meshing with a first gear, and the first gear being fixed on a second rotating shaft.

[0012] Preferably, the flipping mechanism includes a flipping rod, a linkage rack, and a second gear; one end of the flipping rod is rotatably connected to the flipping seat, and the other end is rotatably connected to the fixed seat; the linkage rack meshes with the second gear and moves in the length direction of the linkage rack; one end of the linkage rack is rotatably mounted on the flipping seat; and a hollow guide rod is provided at the bottom of the fixed seat to guide the linkage gear.

[0013] Preferably, the flipping mechanism includes a fourth straight rod, a fifth straight rod rotatably mounted on the fourth straight rod, a sixth straight rod rotatably mounted on the fourth straight rod, a seventh straight rod rotatably mounted on the sixth straight rod, and an eighth straight rod rotatably connected between the fifth straight rod and the seventh straight rod. The fourth straight rod is fixed on the flipping seat, one end of the fifth straight rod is rotatably mounted on the fixed seat, and one end of the seventh straight rod is rotatably mounted on the fixed seat.

[0014] Preferably, the flipping mechanism further includes a cover plate, one end of which is rotatably mounted on the fourth straight rod, and the other end is mounted on the track of the seventh straight rod.

[0015] To achieve the above objectives, in a second aspect, the present invention proposes a mahjong machine that uses the aforementioned folding base.

[0016] Compared with the prior art, the beneficial effects of the folding base for a mahjong machine and the mahjong machine provided by this invention are as follows: When folding, the main unit flips, causing the side of the base's flipping seat closest to the fixed seat to move upwards, while the side of the flipping seat furthest from the fixed seat moves towards the flipping seat, thus achieving the flipping effect. After flipping, the overall space is smaller. At the same time, the center of gravity changes little during the flipping process, making it less likely to tip over.

[0034] participate Figure 1 and Figure 2 A mahjong machine using a folding base includes: a base 1, comprising a fixed seat 11 and a flipping seat 12, with a flipping mechanism 13 between the flipping seat 12 and the fixed seat 11; during folding, the side of the flipping seat 12 away from the fixed seat 11 slowly approaches the fixed seat 11, and the side of the flipping seat 12 close to the fixed seat 11 slowly rises, causing the flipping seat 12 to be tilted or perpendicular to the fixed seat 11; a column 2, mounted on the fixed seat 11; and a main unit 3, rotatably mounted on the column 2. The main unit 3 is the main part of the mahjong machine, containing a shuffling chamber and a mahjong table surface. For ease of understanding, this invention only illustrates the structure connecting the main unit and the column.

[0035] The technical solution of this invention mainly adopts a manual folding method, in which the base is flipped and folded by manually rotating the main unit 3. The linkage between the two is achieved through a linkage structure, which will be described in detail below.

[0036] See Figure 1 , Figure 2 , Figure 5 and Figure 8 A linkage mechanism 4 is provided between the main unit 3 and the base 1. When the main unit 3 is flipped and folded, the linkage mechanism 4 drives the flipping seat 12 to flip and fold. The linkage mechanism 4 includes a first connecting rod assembly 41 symmetrically arranged on the main unit 3, a first rotating shaft 42 arranged between the two first connecting rod assemblies 41, a second connecting rod assembly 43 arranged on the first rotating shaft 42, and a second rotating shaft 44 arranged on the fixed base 11. The first rotating shaft 42 is rotatably arranged on the column 2, and the second rotating shaft 44 is rotatably arranged on the fixed base 11. The first connecting rod assembly 41 includes a first straight rod 411 and a second straight rod 412. One end of the first straight rod 411 is rotatably arranged on the end of the second straight rod 412, and the other end is rotatably arranged on the main unit 3. The other end of the second straight rod 412 is fixed on the first rotating shaft 42. The second linkage assembly 43 includes an L-shaped rod 431, a third straight rod 432, and a transmission mechanism 433. One end of the L-shaped rod 431 is fixed on the first rotating shaft 42, and the other end is rotatably disposed on one end of the third straight rod 432. The other end of the third straight rod 432 is disposed on the transmission mechanism 433, and the transmission mechanism 433 is connected to the second rotating shaft 44.

[0037] Specifically, one side of the main unit 3 is rotatably connected to the column 2. When the main unit 3 is not folded, it can be used normally for playing cards, such as... Figure 1 The main body 3 has a horizontal plate. When the main unit 3 is folded, it is in a vertical position. The rotation positions of the main unit 3 and the column 2 are both located on the right side of the column and the main unit, and the main unit 3 rotates clockwise when folding. The rotation positions of the first straight rod 411 and the main unit 3 are located in the middle of the main unit, making it easier to flip and less likely to interfere. Figures 1-2 When the main unit is pressed, the rotation of the entire main unit 3 causes the first straight rod 411 to rotate, which in turn causes the second straight rod 412 to rotate. The second straight rod 412 then causes the first rotating shaft 42 to rotate clockwise, which in turn causes the L-shaped rod 431 to rotate. The rotation of the L-shaped rod 431 then causes the third straight rod 432 to rise. The third straight rod 432, through the transmission mechanism 433, drives the second rotating shaft 44 to rotate.

[0038] In an optional embodiment, see [link to relevant documentation] Figure 6The transmission mechanism 433 includes a fourth straight rod 4331 rotatably connected to the third straight rod 432, with the other end of the fourth straight rod 4331 fixed to the second rotating shaft 44. When the third straight rod 432 is raised, the fourth straight rod 4331 rotates clockwise, causing the second rotating shaft 44 to rotate as well. This rotation of the second rotating shaft drives the flipping mechanism 13, thus achieving the folding of the base. The flipping mechanism 13 will be described in detail below.

[0039] In another alternative embodiment, see [link to relevant documentation] Figure 8 and Figure 10 The transmission mechanism 433 includes a sector gear 4332 rotatably connected to the third straight rod 432. The sector gear 432 meshes with a first gear 4333, which is fixed on the second rotating shaft 44.

[0040] Specifically, the sector gear 432 is rotatably mounted inside the column. When the third straight rod 432 rises, it drives the sector gear to rotate counterclockwise (from...). Figure 10 (See). The rotation of the sector gear drives the first gear 4333 to rotate counterclockwise, and the first gear 4333 and the second shaft rotate together. The rotation of the second shaft drives the flipping mechanism 13, thereby realizing the folding of the base. The flipping mechanism 13 will be described in detail below.

[0041] There are various structures for the flipping mechanism. This invention will specifically illustrate the flipping structure through two embodiments.

[0042] In an optional embodiment, see [link to relevant documentation] Figure 8 , Figure 9 and Figure 11 The flipping mechanism 13 includes a flipping rod 131, a linkage rack 132, and a second gear 133. One end of the flipping rod 131 is rotatably connected to the flipping seat 12, and the other end is rotatably connected to the fixed seat 11. The linkage rack 132 meshes with the second gear 133 and moves along the length of the linkage rack 132. One end of the linkage rack 132 is rotatably mounted on the flipping seat 12. A hollow guide rod 134 is provided at the bottom of the fixed seat 11 to guide the linkage gear 132.

[0043] Specifically, when folded, the bottom is as follows: Figure 8 As shown. During folding, the second pivot 44 rotates. Second gears 133 are located at both ends of the second pivot 44 and rotate together with it. The second gears 133 drive the linkage rack 132 to move longitudinally, slowly moving it into the hollow guide rod 134. The flipping rod 131 connects the fixed base and the flipping base. After folding, the flipping rod 131... Figure 11As shown. The mounting base has a groove to prevent interference when the flipping rod 131 rotates. The mounting base also has a stepped groove, which, when the flipping base is not folded, perfectly covers the stepped groove to form a complete square shape, preventing the groove from being visible and unsightly.

[0044] In an optional embodiment, see [link to relevant documentation] Figure 2 , Figure 3 , Figure 4 , Figure 7 The flipping mechanism 13 includes a fourth straight rod 135, a fifth straight rod 136 rotatably mounted on the fourth straight rod 135, a sixth straight rod 137 rotatably mounted on the fourth straight rod 135, a seventh straight rod 138 rotatably mounted on the sixth straight rod 137, and an eighth straight rod 139 rotatably connected between the fifth straight rod 136 and the seventh straight rod 138; the fourth straight rod 135 is fixed on the flipping base 12, one end of the fifth straight rod 136 is rotatably mounted on the fixed base 11, and one end of the seventh straight rod 138 is rotatably mounted on the fixed base 11.

[0045] Specifically, during folding, the seventh straight rod 138 is driven by the second pivot to rotate clockwise, while the fourth straight rod 135 remains fixed on the flipping seat. Through the action of various connecting rods, the seventh straight rod 138 drives the fourth straight rod 135 to rotate from horizontal to vertical.

[0046] The flipping mechanism 13 also includes a cover plate 5. One end of the cover plate 5 is rotatably mounted on the fourth straight rod 135, and the other end is mounted on the track 1381 of the seventh straight rod 138. The surface of the cover plate 5 is stepped.

[0047] Specifically, to facilitate the rotation of the seventh straight rod 138, a clearance groove is provided on the fixed base, and a concealing plate 5 is provided for aesthetic purposes. When not folded, the concealing plate perfectly fills the clearance groove. The fixed base also has a stepped groove, which is perfectly covered by the flip base when not folded, forming a complete square shape and preventing the groove from being visible, which would be unsightly. The surface of the concealing plate 5 is stepped, and when not folded, the flip base perfectly covers the low step of the concealing plate 5. The linkage between the concealing plate and the seventh straight rod 138 improves the overall integrity.

[0048] The flipping mechanism 13 also includes a leg storage mechanism 6; the leg storage mechanism 6 includes a leg 61 rotatably mounted on the flipping seat 12, an extension rod 62 extending from the leg 61, and a ninth straight rod 63 rotatably mounted on the extension rod 61, one end of the ninth straight rod 63 being rotatably mounted on the fifth straight rod 136.

[0049] Specifically, when folded, the legs protrude from the base. After flipping, to prevent the legs from protruding and to improve aesthetics, the rotation of the ninth straight rod 63 simultaneously drives the rotation of the fifth straight rod 136, causing the legs 61 to rotate and retract into the base, preventing them from protruding.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
