Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, and in particular to a box-type portable mahjong machine. Background Technology

[0002] Currently, most mahjong machines on the market are fully automatic square mahjong machines, including a table shell, supporting legs, and a control system built into the table shell. The top of the table shell has a tabletop for playing mahjong, and there is an operation panel in the center of the tabletop. The operation panel has control buttons for switching, shuffling, and arranging tiles. The control system is electrically connected to the operation panel and controls the automatic shuffling, arranging, and raising the mahjong tiles to the tabletop.

[0003] For example, Chinese utility model patent (CN222752538U) discloses a box-type portable mahjong machine, which describes: "It includes a box body and a box cover, the box cover and the box body are connected in an openable manner, the outer surface of the box cover constitutes a mahjong game table, and a through hole is opened in the middle of the box cover; the main unit is installed in the box body, and when the box cover and the box body are closed, the inner surface of the box cover is in contact with the top of the main unit, and the card-dispensing port, card-returning port and operation panel of the main unit are exposed from the through hole on the outer surface of the box cover."

[0004] While the aforementioned patents improve the portability of the mahjong machine main unit, the main unit does not include a foldable support leg structure, which means that four additional support leg parts need to be carried when carrying the main unit and temporarily assembled during use. Therefore, this application proposes a box-type portable mahjong machine. Utility Model Content

[0025] As described in the background art, although the above-mentioned patent improves the portability of the mahjong machine host, the host does not include a foldable support leg structure, which means that four additional support leg parts need to be carried when carrying the host and temporarily assembled when in use.

[0026] To solve this technical problem, this utility model provides a box-type portable mahjong machine;

[0027] The device includes a frame shell 1, with a main body 4 fixed inside the frame shell 1. A storage box 8 is provided at the lower end of the frame shell 1. The upper end of the storage box 8 is attached to the bottom end of the main body 4. Two first bearing seats 6 are fixed at the bottom end of the main body 4 and inside the storage box 8. A bearing support plate 7 is rotatably connected to the outer side of each first bearing seat 6. Guide posts 9 are fixed on both sides of the inner side of the storage box 8. Two second bearing seats 10 are slidably connected between the two guide posts 9. The lower ends of the two bearing support plates 7 are rotatably connected to the two second bearing seats 10 respectively. A bidirectional screw 11 is rotatably connected to the center inside the storage box 8. The two second bearing seats 10 are located on the outer sides of both ends of the bidirectional screw 11 and are threadedly connected to the bidirectional screw 11. A limit component is provided between one end of the bidirectional screw 11 and the storage box 8.

[0028] The box-type portable mahjong machine provided by this utility model, through the overall structural design, allows the rotating bidirectional screw 11 to drive the two second shaft seats 10 to move closer to each other through the guide post 9, thereby driving the two supporting plates 7 to stand up and support the main body 4. While improving the portability of the main body 4, there is no need to carry additional support leg parts, thus eliminating the need for temporary assembly which is time-consuming and laborious. In addition, the limiting component is used to limit and fix the bidirectional screw 11 before and after rotation.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1:

[0032] Please refer to Figure 1-4 A box-type portable mahjong machine includes a frame shell 1, a main body 4 fixed inside the frame shell 1, and a protective top cover 2 for the upper end of the main body 4. Four buckling mechanisms 3 are arranged in an array between the outer side of the protective top cover 2 and the frame shell 1.

[0033] In order to support the main body 4 without the need for additional support legs, a storage box 8 is provided at the lower end of the frame shell 1. The upper end of the storage box 8 is attached to the bottom end of the main body 4. Two first bearing seats 6 are fixed at the bottom end of the main body 4 and inside the storage box 8. Guide posts 9 are fixed on both sides of the inner side of the storage box 8. Two second bearing seats 10 are slidably connected between the two guide posts 9. A bearing support plate 7 is rotatably connected to the outer side of each first bearing seat 6. The lower ends of the two bearing support plates 7 are rotatably connected to the two second bearing seats 10 respectively.

[0034] In order to drive the two second shaft seats 10 to move away from or towards each other through the sliding guidance of the guide post 9, thereby controlling the flipping and standing up or flipping and folding of the two supporting plates 7, so as to facilitate the flexible unfolding or folding of the main body 4, a bidirectional screw 11 is rotatably connected at the center of the storage box 8. The two second shaft seats 10 are located on the outer side of the two ends of the bidirectional screw 11 and are threadedly connected to the bidirectional screw 11. In order to limit and fix the bidirectional screw 11 before and after rotation, thereby locking the position of the two second shaft seats 10, a limit component is provided between one end of the bidirectional screw 11 and the storage box 8.

[0035] Specifically, a handle 12 is fixed to one end of the bidirectional screw 11 and located on the outside of the storage box 8. The limiting component includes a first spur gear 13. The first spur gear 13 is fixed to the outside of the end of the bidirectional screw 11 near the handle 12. A gear groove 14 is opened inside the storage box 8 and located outside the first spur gear 13. A second spur gear 15 is slidably connected to the inside of the gear groove 14. One end of the second spur gear 15 is meshed with the first spur gear 13. A first spring 16 is fixed to the other end of the second spur gear 15. The first spring 16 is located inside the gear groove 14. The end of the first spring 16 away from the second spur gear 15 is fixed to the storage box 8.

[0036] A portable handle 5 is fixed to one end of the outer shell 1, and the portable handle 5 is located at the upper end of the handle 12.

[0037] Example 2:

[0038] The portable mahjong machine in Example 1 has been further optimized, specifically, as follows: Figure 5-6As shown, when the two second shaft seats 10 are driven to approach each other and cause the two bearing plates 7 to flip and stand up, thereby supporting the main body 4, in order to further assist the bearing plates 7 in improving their bearing performance and thus ensure stable support for the main body 4, outer supports 17 are fixed at the four corners of the outer side of the frame shell 1. Each outer support 17 has a support shaft 18 fixed at its lower end. The outer side of the support shaft 18 is rotatably connected to the auxiliary support leg 19 and the mounting base 20, respectively. The outer side of the auxiliary support leg 19 is in contact with the frame shell 1 and the storage box 8, respectively.

[0039] When the main body 4 is separated from the storage box 8, and then the four auxiliary legs 19 are flipped and unfolded around the support shaft 18, in order to lock the four auxiliary legs 19, a positioning slide rod 21 is slidably connected to the end of the mounting base 20 away from the support shaft 18. One end of the positioning slide rod 21 passes through the outer support 17 and is slidably connected to the outer shell 1 and the auxiliary legs 19 respectively. The positioning slide rod 21 is slidably connected to the outer support 17. A second spring 22 is sleeved on the outer side of the other end of the positioning slide rod 21. The two ends of the second spring 22 are fixed to the positioning slide rod 21 and the mounting base 20 respectively.

[0040] The usage process of the box-type portable mahjong machine provided by this utility model is as follows: (e.g.) Figure 1 As shown, when the main body 4 needs to be used, first open the four latching mechanisms 3 and then remove the protective top cover 2 from the top of the main body 4. Then press the second flat gear 15 so that it slides into the gear groove 14 and squeezes the first spring 16, so that the meshing of the second flat gear 15 and the first flat gear 13 is released, thereby making it easier to grip the handle 12 and rotate the bidirectional screw 11. The bidirectional screw 11 is connected to the two second shaft seats 10 by threads, which drives the two second shaft seats 10 to move closer to each other through the sliding guidance of the guide post 9. With the rotational connection of the bearing plate 7 with the second shaft seat 10 and the first shaft seat 6, the two bearing plates 7 are rotated and stood up to support the main body 4.

[0041] After the two support plates 7 have been flipped over and the teeth of the second flat gear 15 are aligned with those of the first flat gear 13, the second flat gear 15 is released and the elasticity of the first spring 16 is used to push the second flat gear 15 back to its original position, so that the second flat gear 15 re-meshes with the first flat gear 13, thereby limiting the rotation of the bidirectional screw 11 and fixing the two support plates 7.

[0042] Simultaneously, after the two supporting plates 7 are flipped upright, the four auxiliary legs 19 lose their support and, using their own weight, cause the four auxiliary legs 19 to flip vertically around the support shaft 18, as shown. Figure 2 As shown;

[0043] At this time, pull the positioning slide rod 21 to make it slide out from the frame shell 1 and the outer support 17, so as to facilitate the 180-degree flip of the mounting base 20. Then release the positioning slide rod 21, and use the elasticity of the second spring 22 to push the positioning slide rod 21 back into the auxiliary support leg 19 to lock the auxiliary support leg 19. With the auxiliary support of the four auxiliary support legs 19, the overall load-bearing capacity is further improved, thereby ensuring stable support for the main body 4.
