Furthermore, in terms of maintenance, if damaged by bumps or knocks, the only option is often to replace the entire machine. These drawbacks limit the usage scenarios and convenience of existing cubic mahjong machines, failing to meet people's growing demands for portability and affordability. Therefore, developing a new type of mahjong machine that can solve these problems has become an urgent priority. Utility Model Content
[0004] In view of this, the present invention provides a detachable and retractable blind box mahjong machine to solve the technical problem that existing mahjong machines are large in size and inconvenient to store.
[0005] An embodiment of this utility model provides a detachable, retractable blind box mahjong machine, comprising: Four separate modules, which can be detachably connected to form a rectangular blind box mahjong machine; Each of the aforementioned modular components also includes an arc-shaped receiving portion and two table legs. The four receiving portions of the four modular components together form a mahjong tile receiving space extending towards the lower part of the modular component. The two adjacent table legs of the two modular components are joined together to form one table leg of the blind box mahjong machine. The eight table legs of the four modular components are joined together to form four rectangularly distributed table legs to support the blind box mahjong machine. A panel, which is detachably connected to the four separate modules, covers the upper part of the mahjong tile receiving space, so that the mahjong tiles in the mahjong tile receiving space are covered and hidden.
[0006] Furthermore, the four separate modules are divided diagonally along the rectangular blind box mahjong machine, or cross-shaped along the midpoints of the four sides of the rectangular blind box mahjong machine.
[0007] Furthermore, adjacent modular units are detachably connected by a snap-fit structure, which includes a male snap-fit and a female snap-fit. Each modular unit is divided to form two splicing surfaces, with the male snap-fit and the female snap-fit located on the two splicing surfaces respectively.

[0024] Please refer to Figure 1 and Figure 2 The present invention provides a detachable storage blind box mahjong machine with an equal division structure, which is easy to disassemble and store, convenient to assemble and effectively reduces maintenance costs, while not affecting the normal use of mahjong tiles.
[0025] The blind box mahjong machine consists of four separate modules 1 and a panel 2. These four separate modules 1 can be detached and connected, and finally assembled to form a complete rectangular blind box mahjong machine.
[0026] In terms of the division method, multiple schemes can be adopted: it can be divided diagonally along the rectangle of the blind box mahjong machine, or it can be divided into four equal parts along the midpoints of the four sides of the rectangle of the blind box mahjong machine.
[0027] Both of these division methods ensure that each separate module 1 fits precisely when assembled, and facilitate subsequent disassembly and storage.
[0028] Please see Figure 1 and Figure 3 In this embodiment, each modular unit 1 includes an arc-shaped receiving portion 4 and two table legs 8, and the receiving portion 4 and the table legs 8 are integrally transitioned by an extended edge 5.
[0029] When the four compartments 4 of the four separate modules 1 are closed together, they form a mahjong tile storage space that extends towards the lower part of the separate modules 1, which is used to store mahjong tiles.
[0030] The two adjacent table legs 8 of the two separate modules 1 are combined to form one table leg of the blind box mahjong machine. The eight table legs 8 of the four separate modules 1 are combined to form four rectangular table legs, thus stably supporting the entire blind box mahjong machine.
[0031] The extended edge 5 is designed so that when two adjacent sub-modules 1 are spliced together, the extended edges 5 of the two sub-modules come into contact with each other, which plays a certain role in positioning and transition, making the splicing smoother and tighter.
[0032] It should be noted that, in a specific embodiment, please refer to... Figure 3 and Figure 4 Both the receiving part 4 and the table leg part 8 are provided with positioning structures 10. Each positioning structure 10 includes a platform 6 and a locking block 7. The locking block 7 is perpendicular to the platform 6 to form an inverted T-shaped platform.
[0033] One end of the platform 6 is connected to a split module 1. A rectangular gap is reserved between the locking block 7 and the split module 1. A notch 9 is provided on the extension edge 5 of each split module 1. The notch 9 and the gap formed between the locking block 7 and the split module 1 have the same width.
[0034] When splicing two adjacent sub-modules 1, the extension edge 5 of one can be embedded from top to bottom into the gap between the locking block 7 of the other sub-module 1 and the sub-module 1, thereby achieving pre-positioning of the two adjacent sub-modules 1, making the splicing process more convenient and accurate, and avoiding inaccurate splicing situations such as misalignment.
[0035] Example 1: Please refer to Figure 3 and Figure 4 Adjacent modular units 1 are detachably connected via a snap-fit structure.
[0036] Specifically, each split module 1 is divided into two splicing surfaces, with male and female buckles located on the two splicing surfaces respectively. The male buckle includes a protrusion 11 and a locking block 12, and the female buckle includes a groove 13 and a slot 14. The protrusion 11 and the groove 13 are inserted into each other, and the locking block 12 and the slot 14 are fastened together.
[0037] When assembling, align the male and female snaps of the two adjacent split modules 1, apply appropriate pressure to insert the protrusion 11 into the groove 13, and at the same time, the locking block 12 and the locking groove 14 are engaged, thereby achieving a stable connection between the two split modules 1.
[0038] This snap-fit design makes the connection operation simple and easy, and the overall structure is stable and reliable after connection. It can withstand various stresses during normal use of the mahjong machine, ensuring that the normal function of the mahjong machine is not affected. When it is necessary to disassemble and store, just apply appropriate external force to overcome the snap-fit force, and the split module 1 can be easily disassembled.
[0039] Example 2: Adjacent modular modules 1 are connected using a pin-locking method. Specifically, connection holes are pre-set on the extension edges 5 of modular modules 1 used for splicing. When two modular modules 1 need to be spliced together, the connection holes on the extension edges 5 of the adjacent modules are aligned, and then the pins are inserted into the connection holes. Through the locking function of the pins, the adjacent modular modules 1 are stably connected together, realizing the combination and splicing of the modules.
[0040] This pin-locking connection method offers high connection strength and stability, effectively preventing displacement or loosening of the split module 1 during use, ensuring the reliability and stability of the overall structure of the mahjong machine during normal operation. Simultaneously, the pins are relatively easy to install and remove, facilitating quick disassembly of the split module 1 when maintenance, cleaning, or storage of the mahjong machine is required, thus improving ease of use and management.
[0041] Furthermore, to enhance the stability of the pin-locking connection, an anti-slip structure or locking device can be installed on the pin to further prevent it from loosening under external force, ensuring a tight and reliable connection between the separate modules 1. Simultaneously, the shape and size of the pin and connecting hole can be optimized according to actual needs to accommodate separate modules 1 of different sizes and shapes, improving their versatility and applicability, thereby better meeting the diverse design and usage requirements of mahjong machines.
[0042] Example 3: In this example, a groove is made on the surface of the extended edge 5, and then a strong magnetic block is fixed in the groove. In this way, the four separate modules 1 can be magnetically attracted and assembled with each other using the strong magnetic blocks on adjacent extended edges 5 to form a complete blind box mahjong machine body.
[0043] The application of magnetic connection makes the splicing process between the separate modules 1 simple and quick. Adjacent modules simply need to be brought close together, and they automatically adhere and assemble using magnetic force, eliminating the need for complex connection operations and auxiliary tools, thus greatly improving assembly efficiency. Furthermore, the magnetic connection offers excellent detachability; when the mahjong machine needs to be disassembled for storage, transport, or module replacement, the separate modules 1 can be easily separated, which is convenient and quick without damaging the modules themselves.
[0044] To ensure the firmness and stability of the magnetic assemblies, the selected strong magnetic blocks should have sufficient magnetic force to overcome various forces generated during normal use of the mahjong machine, such as the impact force and vibration of the mahjong tiles, and prevent the separate module 1 from accidentally separating during use, thus affecting the normal use of the mahjong machine.
[0045] Meanwhile, the design of the extended edge 5 can be optimized, such as by increasing the number of magnetic blocks or adjusting their layout, to further enhance the uniform distribution of magnetic attraction and overall connection strength. Furthermore, considering the aesthetics of the plastic extended edge 5, the grooves and strong magnetic blocks can be designed to be hidden, ensuring the magnetic attraction function without affecting the overall appearance and design style of the blind box mahjong machine, thus improving the product's visual appeal and market competitiveness.
[0046] Please see Figure 5 and Figure 6In order to stack and store the four separate modules 1 after disassembly, the outer perimeter of each separate module 1 is enclosed by the extended edge 5 to form a stacking space.
[0047] When storing, the four separate modules 1 can be embedded into adjacent stacking spaces in the vertical direction for stacking and storage. This stacking method is commonly seen in the way plastic stools are stacked in daily life.
[0048] Additionally, it should be noted that in this embodiment, the split module 1 can be a plastic part with a certain degree of deformation elasticity. In this way, split modules 1 of the same size and specifications can be embedded and stacked through their own deformation, and at the same time, under their own elastic force, adjacent split modules 1 can be fixed.
[0049] This stacking and storage method greatly saves storage space, making the blind box mahjong machine easier to store when not in use. It is especially suitable for scenarios where home space is limited and frequent storage or carrying is required, thus improving its practicality and portability.
[0050] In order to connect panel 2 to the assembled blind box mahjong machine, each split module 1 has a raised edge 3 on its upper part. After the four split modules 1 are assembled, the four raised edges 3 enclose a rectangular frame.
[0051] Panel 2 is snapped into the rectangular frame, so that panel 2 can be detachably connected to the upper part of the mahjong tile holding space formed by the four separate modules 1, thereby concealing the mahjong tiles in the mahjong tile holding space, increasing the fun and mystery of the mahjong machine before use. A circular tile-taking opening runs through the middle of panel 2, and a covering cloth 17 is set at the tile-taking opening.
[0052] The specific covering cloth 17 is made of elastic fabric, which can effectively cover the mahjong tiles below the panel 2, so that the user cannot directly see the arrangement of the mahjong tiles before taking them.
[0053] Furthermore, each protrusion edge 3 is provided with a protruding strip 15 on the side facing the receiving part 4. The outer periphery of the panel 2 is engaged with the four protruding strips 15. This engagement structure further enhances the stability of the panel 2 installation, ensuring that the panel 2 will not easily loosen or fall off during use, while also facilitating quick disassembly of the panel 2 when it is necessary to view or organize the mahjong tiles.
[0054] Additionally, each modular unit 1 has a recessed groove 16 on its surface for placing mahjong tiles. The depth of the groove 16 corresponds to the height of the mahjong tiles. The depth of the groove 16 can be one-third of the height of the mahjong tiles to prevent them from tipping over.
[0055] When the assembled blind box mahjong machine is in use, the mahjong tiles can be neatly placed in these receiving slots 16, ensuring that the mahjong tiles are placed stably and will not shake or tip over, providing users with a good user experience and facilitating mahjong games and other entertainment activities.
[0056] The blind box mahjong machine is formed by assembling four separate modules 1 to create a non-powered mahjong table for entertainment. The four compartments 4 surround the mahjong tiles to form a space for holding the tiles. Users can pour the matching bagged mahjong tiles into the compartment and hide the tiles using the panel 2. At this time, users can experience a way of drawing tiles similar to blind boxes.
[0057] In this document, the directional terms such as front, back, top, and bottom are defined based on the location of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on the method of use and placement; the use of directional terms should not limit the scope of protection claimed in this application.
[0058] Where there is no conflict, the above embodiments and features described herein can be combined with each other.
[0059] 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.
