Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to a multifunctional combination cabinet. Background Technology

[0002] With the booming development of the furniture technology field, significant changes have taken place from design to production. In design, with the help of advanced technologies such as computer-aided design (CAD) and virtual reality (VR), designers can plan furniture shapes and functions more accurately. In production, technologies such as CNC machine tools and 3D printing have made complex structures and personalized customization possible, while advances in materials science have also provided furniture with more diverse choices.

[0003] Even with continuous technological advancements, some furniture still falls short in terms of space utilization. Take cabinets as an example: traditional wardrobes, bookcases, and storage cabinets, designed to meet large storage needs, are often very tall, heavy, and deep. Especially custom-made cabinets, once installed, are difficult to alter, appearing particularly out of place in small apartments, not only compressing living space but also making the room feel cramped and oppressive. Similarly, while large sideboards offer ample storage, for families with limited dining space, the remaining space after placement is insufficient for daily dining activities. These issues of excessive furniture size are gradually becoming a major obstacle to the comfort and practicality of home spaces. Utility Model Content

[0004] This application discloses a multifunctional combination cabinet that combines the cabinet body and dining table into one unit, saving residents' space. The cabinet's smaller size allows for the storage of a dining table with a larger usable space, and the supporting table legs are also stored on the dining table, occupying minimal cabinet space.

[0005] To achieve the above objectives, this application discloses a multi-functional combination cabinet, which includes:

[0006] The cabinet has a storage cavity and a storage opening communicating with the storage cavity;

[0007] The main table body has its first end rotatably connected to the storage opening of the cabinet, so that the main table body can switch between a use state and a storage state. When the main table body is in the storage state, the main table body is stored in the storage cavity. When the main table body is in the use state, the main table body extends horizontally out of the storage cavity, and the tabletop of the main table body faces upward.

[0008] A folding tabletop is rotatably connected to the main table body so that the folding tabletop can rotate between a folded state and an unfolded state. When the folding tabletop is in the folded state, it is stacked on the tabletop of the main table body. When the folding tabletop is in the unfolded state, the tabletop of the folding tabletop and the tabletop of the main table body are on the same plane.

[0009] A support component is movably connected to the main table body so that the support component can switch between a retracted state and an extended state. When the support component is in the retracted state, it is stored in the side of the main table body away from the tabletop. When the support component is in the extended state, at least a portion of the support component extends out of the main table body and corresponds to the position of the folding tabletop in the unfolded state to support the folding tabletop.

[0010] As an optional implementation, the main table body includes a main table frame and a main table panel connected to the main table frame. The main table frame is rotatably connected to the cabinet. The main table frame has a storage space. When the support component is in the retracted state, the support component is stored in the storage space, and the folding table panel is rotatably connected to the main table panel.

[0011] As an optional implementation, the support assembly is slidably connected to the main table frame, the main table frame having an opening communicating with the storage space, and the support assembly being able to extend out of the main table frame through the opening.

[0012] As an optional implementation, the folding tabletop is rotatably connected to the second end of the main table body, and the second end of the main table body is opposite to the first end of the main table body in a first direction. When the folding tabletop is in the unfolded state, the folding tabletop and the main tabletop are arranged in the first direction, and the support assembly is slidably connected to the main table frame along the first direction.

[0013] As an optional implementation, the support component includes:

[0014] A support frame, which is slidably connected to the main table frame along the first direction;

[0015] The table legs are rotatably connected to the end of the support frame away from the cabinet. When the support assembly is in the retracted state, both the support frame and the table legs are stored in the storage space. When the support assembly is in the extended state, the support frame extends at least partially out of the main table body, and the table legs are supported on the ground in a vertical direction.

[0016] As an optional implementation, the multifunctional combination cabinet further includes a rotating connection assembly, which is disposed on the support frame, and the table legs are rotatably connected to the rotating connection assembly;

[0017] The rotating connection assembly includes a fixing member, an elastic member, a positioning ball, and a rotating shaft. The first end of the fixing member is fixedly connected to the support frame, and the rotating shaft passes through the second end of the fixing member and the first end of the table leg, so that the first end of the table leg can rotate around the rotating shaft.

[0018] The second end of the fastener is provided with a clearance groove to avoid the first end of the support member;

[0019] The first end of the fixing member is provided with a mounting hole, which extends in a direction perpendicular to the tabletop of the main table body. The mounting hole communicates with the clearance groove. The elastic member and the positioning ball are both disposed in the mounting hole. The inner diameter of the mounting hole gradually decreases in the direction away from the support frame. The minimum inner diameter of the mounting hole is smaller than the diameter of the positioning ball. The positioning ball is located between the table leg and the elastic member, and is partially located outside the mounting hole. The first end of the table leg is provided with a limiting groove. The shape of the limiting groove is adapted to the shape of the portion of the positioning ball located outside the mounting hole. The elastic member can apply a force perpendicular to the folding table board to the positioning ball so that when the table leg rotates to the extended state, the positioning ball abuts against the limiting groove to limit the degree of freedom of the table leg in its own rotation direction.

[0020] As an optional implementation, the main table body has a fixed frame on the side away from the tabletop. When the table legs are stored in the storage space, the second end of the table legs can be engaged with the fixed frame. The second end of the table legs is the end of the table legs that contacts the ground.

[0021] As an optional implementation, the multifunctional combination cabinet further includes a first rotating bearing, a second rotating bearing, and a rotating connecting rod. The cabinet body is provided with a first mounting groove, and the main table frame is provided with a second mounting groove. The first mounting groove and the second mounting groove are positioned correspondingly. The first rotating bearing is disposed in the first mounting groove, and the second rotating bearing is disposed in the second mounting groove. The first end of the rotating connecting rod is connected to the first rotating bearing, and the second end of the rotating connecting rod is connected to the second rotating bearing.

[0022] As an optional implementation, the cabinet is provided with a snap-fit ​​connector, and the main table frame is provided with a snap-fit ​​groove. When the main table is in the stored state, the snap-fit ​​connector is located in the snap-fit ​​groove to limit the degree of freedom of the main table along its own rotation direction.

[0023] As an optional implementation, the main tabletop is provided with a first magnetic component, and the folding tabletop is provided with a second magnetic component. The first magnetic component and the second magnetic component can generate an adsorption force so that when the folding tabletop is in the folded state, the folding tabletop and the main tabletop are attracted to each other.

[0024] Compared with the prior art, the beneficial effects of this application are:

[0025] The multifunctional combination cabinet provided in this application embodiment allows the main table to switch between a usable and a folded state. When not in use, it can be stored in the cabinet's storage compartment. The folding tabletop can be stacked on the main table's surface when not in use, and unfolded to be flush with the main table's surface when in use. The support components are stored on the side of the main table away from the surface when not in use, occupying minimal space. When needed, the support components extend to support the folding tabletop. The main table and the folding tabletop together form a large dining table. This design allows the large dining tabletop to be stored in a relatively small space when not in use, effectively saving indoor space. The support components can also be stored in the storage compartment, avoiding additional space occupation, making the entire combination cabinet more compact when folded. In daily life, when there is a need for dining, the main table and the folding tabletop can be unfolded to form a complete dining table; after dining, they can be folded up, and the cabinet can be used as ordinary storage furniture, realizing the diversification of furniture functions and improving the efficiency of furniture use.

[0043] With the booming development of the furniture technology field, significant changes have taken place from design to production. In design, with the help of advanced technologies such as computer-aided design (CAD) and virtual reality (VR), designers can plan furniture shapes and functions more accurately. In production, technologies such as CNC machine tools and 3D printing have made complex structures and personalized customization possible, while advances in materials science have also provided furniture with more diverse choices.

[0044] Even with continuous technological advancements, some furniture still falls short in terms of space utilization. Take cabinets as an example: traditional wardrobes, bookcases, and storage cabinets, designed to meet large storage needs, are often very tall, heavy, and deep. Especially custom-made cabinets, once installed, are difficult to alter, appearing particularly out of place in small apartments, not only compressing living space but also making the room feel cramped and oppressive. Similarly, while large sideboards offer ample storage, for families with limited dining space, the remaining space after placement is insufficient for daily dining activities. These issues of excessive furniture size are gradually becoming a major obstacle to the comfort and practicality of home spaces.

[0045] Currently, dining tables and sideboards are sold separately, requiring customers to purchase them individually. This increases the budget, and separate dining tables and sideboards take up a significant amount of dining space, making them unsuitable for small apartments. Some two-in-one combination cabinets have one tabletop stored within the cabinet, which takes up considerable space and is inconvenient to store; when both tabletops are folded and stored, the legs require additional cabinet space.

[0046] Based on this, this application discloses a multifunctional combination cabinet that can combine the cabinet body and the dining table into one, saving residents' space. The smaller space of the cabinet can accommodate the dining table with a larger usable space, and the supporting table legs are also stored on the dining table, occupying little storage space in the cabinet.

[0047] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0048] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the multifunctional combination cabinet 100 disclosed in the embodiments of this application (with the main table body 2 in a folded-back state); Figure 2 This is a schematic diagram showing the main table body 2 in use, the folding tabletop 3 in unfolded state, and the support component 4 in extended state, as disclosed in this application embodiment. This application embodiment discloses a multi-functional combination cabinet 100, which includes a cabinet body 1, a main table body 2, a folding tabletop 3, and a support component 4. The cabinet body 1 has a storage cavity 1a and a storage opening 1b communicating with the storage cavity 1a. The first end of the main table body 2 is rotatably connected to the storage opening 1b of the cabinet body 1, allowing the main table body 2 to switch between a use state and a storage state. When the main table body 2 is in the storage state, it is stored within the storage cavity 1a. When the main table body 2 is in the use state, it extends horizontally out of the storage cavity 1a, with the tabletop facing upwards. The folding tabletop 3 is rotatably connected to the main table body 2, allowing the folding tabletop to... 3. It can rotate between a folded state and an unfolded state. When the folded table 3 is in the folded state, it is stacked on the tabletop of the main table 2. When the folded table 3 is in the unfolded state, the tabletop of the folded table 3 and the tabletop of the main table 2 are on the same plane. The support component 4 is movably connected to the main table 2 so that the support component 4 can switch between a retracted state and an extended state. When the support component 4 is in the retracted state, it is stored in the side of the main table 2 away from the tabletop. When the support component 4 is in the extended state, at least a part of the support component 4 extends out of the main table 2 and corresponds to the position of the folded table 3 in the unfolded state to support the folded table 3.

[0049] When the user is not dining, the folding tabletop 3 is folded, the support component 4 is retracted, and stored behind the main table body 2. Then, the main table body 2 is rotated to the storage state so that the main table body 2, the folding tabletop 3, and the support component 4 are stored together in the storage cavity 1a. When the user is dining, the main table body 2 is rotated to the horizontally extended use state, and the support component 4 is extended. Then, the folding tabletop 3 is rotated to the unfolded state. The cabinet 1 can support the main table body 2, and the support component 4 can support the folding tabletop 3. The tabletop of the main table body 2 and the tabletop of the folding tabletop 3 together form the dining table.

[0050] In this way, the main table 2 can be switched between a usable and a stored state. When not in use, it can be stored in the storage cavity 1a of the cabinet 1. The folding tabletop 3 can be stacked on the tabletop of the main table 2 when not in use, and unfolded to be on the same plane as the tabletop of the main table 2 when in use. The support component 4 is stored on the side of the main table 2 away from the tabletop when not in use, occupying little space. When needed, the support component 4 extends to support the folding tabletop 3. The main table 2 and the folding tabletop 3 together form a large dining table. This design allows the large dining tabletop to be stored in a relatively small space when not in use, effectively saving indoor space. The support component 4 can also be stored in the storage cavity 1a, avoiding additional space occupation, making the entire combination cabinet more compact when stored. In daily life, when there is a need for dining, the main table 2 and the folding tabletop 3 can be unfolded to form a complete dining table; after the meal, they can be stored away, and the cabinet 1 can be used as ordinary storage furniture, realizing the diversification of furniture functions and improving the efficiency of furniture use.

[0051] As an optional implementation method, combined with Figure 1 and Figure 2 The main table body 2 includes a main table frame 21 and a main table board 22 connected to the main table frame 21. The main table frame 21 is rotatably connected to the cabinet 1. The main table frame 21 and the main table board 22 form a storage space 21a. When the support component 4 is in the retracted state, the support component 4 is stored in the storage space 21a. The folding table board 3 is rotatably connected to the main table board 22.

[0052] The main table frame 21 incorporates a storage space 21a to house the support component 4. When the support component 4 is retracted, it can be hidden within this space, making full use of the interior space of the main table body 2. This design prevents the support component 4 from occupying extra space, making the entire multi-functional combination cabinet 100 more compact when retracted. For example, in a small living room, limited space does not allow for excessive furniture volume. Storing the support component 4 within the main table frame 21 prevents its protrusion from affecting the overall layout and living space of the room.

[0053] The main table frame 21 and the main tabletop 22 each serve different functions. The main table frame 21 is primarily responsible for the rotatable connection with the cabinet 1 and the storage of the support component 4, while the main tabletop 22 provides the actual tabletop for use. This functional independence allows each component to be optimized for its specific function during design and manufacturing, improving product performance and quality. Although the main table frame 21 and the main tabletop 22 are functionally independent, they cooperate to form the complete function of the main table body 2. The main table frame 21 provides stable support and a rotatable foundation for the main tabletop 22, enabling the main table body 2 to smoothly switch between its use and storage states. Simultaneously, the connection between the main tabletop 22 and the folding tabletop 3 also relies on the structural support of the main table frame 21, ensuring the normal operation of the entire dining table.

[0054] In some embodiments, combined with Figure 1 and Figure 2 The support component 4 is slidably connected to the main table frame 21, which has an opening communicating with the storage space 21a, and the support component 4 can extend out of the main table frame 21 through the opening.

[0055] The support component 4 is slidably connected to the main table frame 21, making it easy to switch between the folded and extended states. Users can simply push or pull the support component 4 to allow it to slide smoothly within the main table frame 21, without complicated installation or disassembly steps, thus improving the convenience of using the furniture. Moreover, this sliding connection design allows for one-handed operation in many situations. For example, when the dining table needs to be quickly unfolded, the user can use one hand to slide the support component 4 out of the main table frame 21, while the other hand can simultaneously perform other auxiliary operations, such as tidying the tabletop or rotating the folding tabletop 3, greatly saving time and effort.

[0056] The opening on the main table frame 21 connects to the storage space 21a, ensuring that the support component 4 can accurately extend and retract from the storage space 21a. When stored, the support component 4 can be completely retracted into the main table frame 21, without occupying extra space due to positional displacement. When extended, it can also accurately reach the position supporting the folding tabletop 3 along a fixed path, ensuring that the entire multi-functional combination cabinet 100 can efficiently utilize space in different states.

[0057] Optionally, combined Figures 1 to 3 , Figure 3This is a schematic diagram of the folding table 3 disclosed in this application during the folding process. The folding table 3 is rotatably connected to the second end of the main table body 2. The second end of the main table body 2 is opposite to the first end of the main table body 2 in the first direction X. When the folding table 3 is in the unfolded state, the folding table 3 and the main table 22 are arranged in the first direction X. The support component 4 is slidably connected to the main table frame 21 along the first direction X. In use, the support component 4 is pulled out to support the folding table 3 and the main table 22.

[0058] In restaurants with limited space, if the space is relatively spacious in one direction, this method of expanding the table in one direction can better adapt to the spatial layout and avoid the space becoming crowded due to the table being expanded arbitrarily in multiple directions, thus making more efficient use of the limited space.

[0059] When the folding tabletop 3 needs to be unfolded, simply slide the support component 4 out along the first direction X to accurately reach the position supporting the folding tabletop 3. The operation is simple and direct, improving the convenience and efficiency of using the dining table. Users can simultaneously operate the unfolding of the folding tabletop 3 and the extension of the support component 4, further enhancing the ease of operation.

[0060] The support component 4 is positioned corresponding to the folding tabletop 3 and is arranged in the same direction, enabling the support component 4 to provide stable and uniform support for the folding tabletop 3. When people place items or engage in activities such as dining on the folding tabletop 3, the support component 4 can effectively distribute the pressure, preventing the tabletop from deforming or being damaged due to excessive local stress, thus improving the overall stability and durability of the dining table.

[0061] Optionally, the folding tabletop 3 is rotatably connected to the main tabletop 22 via a hinge. The hinge structure is simple and can provide stable support and connection for the folding tabletop 3.

[0062] In some embodiments, combined with Figures 3 to 5 , Figure 4 This is a schematic diagram of the folding table 3 in a folded state as disclosed in an embodiment of this application; Figure 5 This is a schematic diagram of the table leg 42 in the rotation process disclosed in this application embodiment. The support component 4 includes a support frame 41 and a table leg 42. The support frame 41 is slidably connected to the main table frame 21 along the first direction X. The table leg 42 is rotatably connected to the end of the support frame 41 away from the cabinet 1. When the support component 4 is in the retracted state, both the support frame 41 and the table leg 42 are stored in the storage space 21a. When the support component 4 is in the extended state, the support frame 41 extends at least partially out of the main table body 2, and the table leg 42 is supported on the ground in the vertical direction.

[0063] The support frame 41 is slidably connected to the main table frame 21 along the first direction X, making the extension and retraction of the support component 4 simpler and more convenient. Users only need to gently push or pull the support frame 41 to make it slide smoothly within the main table frame 21, thus switching the state of the support component 4. Moreover, this sliding connection method has good guidance during operation, reducing the possibility of operational errors.

[0064] The table leg 42 is rotatably connected to the end of the support frame 41 away from the cabinet 1. When the support assembly 4 is in the extended state, the table leg 42 supports the ground vertically. This structural design provides stable support for the unfolded folding tabletop 3. Moreover, the support frame 41 can abut against the two opposite edges of the folding tabletop 3 perpendicular to the first direction X, evenly distributing the pressure on the folding tabletop 3. The vertically supporting table leg 42 can effectively support the support frame 41. The support frame 41 and the table leg 42 simultaneously support the folding tabletop 3, improving the safety and stability of the modular cabinet.

[0065] Furthermore, the support assembly 4 is divided into two parts: the support frame 41 and the table legs 42, which facilitates individual replacement when parts are damaged or require maintenance. If the table legs 42 are worn or damaged, users can easily remove them from the support frame 41 for replacement without having to replace the entire support assembly 4, thus reducing maintenance costs and difficulty.

[0066] In some embodiments, combined with Figure 9 , Figure 9 This is a schematic diagram of the guide rail and sliding member 411 disclosed in the embodiment of this application. The main table frame 21 is provided with a guide groove 24. When the main table board 22 is in the use state of extending in the horizontal direction, the guide groove 24 extends in the first direction X. The support frame 41 is provided with a sliding member 411. The sliding member 411 can slide in the guide groove 24 so that the support frame 41 moves closer to or away from the cabinet 1 in the first direction X.

[0067] The cooperation between the guide rail and the slider 411 allows the support assembly 4 to slide smoothly within the main table frame 21. The guide rail provides a precise movement trajectory for the slider 411, reducing friction and jamming during the sliding process. When switching the support frame 41 from the retracted state to the extended state, or vice versa, the user can easily complete the operation by simply pushing or pulling it with a little force.

[0068] As an optional implementation method, combined with Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the rotating connection assembly 5 disclosed in the embodiments of this application; Figure 7This is an exploded view of the rotating connection assembly 5 disclosed in an embodiment of this application. The multi-functional combination cabinet 100 also includes the rotating connection assembly 5, which is disposed on the support frame 41, and the table legs 42 are rotatably connected to the rotating connection assembly 5.

[0069] The rotating connection assembly 5 includes a fixing member 51, an elastic member 52, a positioning ball 53, and a rotating shaft 54. The first end of the fixing member 51 is fixedly connected to the support frame 41. The rotating shaft 54 ​​passes through the second end of the fixing member 51 and the first end of the table leg 42, so that the first end of the table leg 42 can rotate around the rotating shaft 54. The second end of the fixing member 51 is provided with a clearance groove 51a to avoid the first end of the support member. The rotating shaft 54 ​​passes through the clearance groove 51a to connect the fixing member 51 and the table leg 42 together.

[0070] The first end of the fastener 51 is provided with a mounting hole 51b, which extends along the direction perpendicular to the tabletop of the main table body 2. The mounting hole 51b communicates with the clearance groove 51a. The elastic element 52 and the positioning ball 53 are both disposed in the mounting hole 51b. The inner diameter of the mounting hole 51b gradually decreases along the direction away from the support frame 41. The minimum inner diameter of the mounting hole 51b is smaller than the diameter of the positioning ball 53, so that the positioning ball 53 is partially located in the positioning hole while ensuring that it is always located in the mounting hole 51b and will not fall out. The positioning ball 53 is located between the table leg 42 and the elastic element 52. The first end of the table leg 42 is provided with a limiting groove 42a. The shape of the limiting groove 42a is adapted to the shape of the part of the positioning ball 53 outside the mounting hole 51b, so that the positioning ball 53 can fit tightly against the groove wall of the limiting groove 42a.

[0071] The elastic element 52 can apply a force perpendicular to the folding tabletop 3 to the positioning ball 53 so that when the table leg 42 rotates to the extended state, the positioning ball 53 abuts against the limiting groove 42a to limit the degree of freedom of the table leg 42 in its own rotation direction.

[0072] The first end of the table leg 42 includes a smooth curved surface. When the table leg 42 is in the retracted state, the positioning ball 53 abuts against the smooth curved surface of the table leg 42 under the force of the elastic element 52. During the process of the table leg 42 rotating from the retracted state to the extended state, the positioning ball 53 slides relative to the smooth curved surface of the table leg 42 until the limiting groove 42a of the table leg 42 rotates to the position corresponding to the positioning ball 53. At this point, the positioning ball 53 tightly abuts against the limiting groove 42a of the table leg 42. Under the force applied by the elastic element 52 to the positioning ball 53 perpendicular to the folding tabletop 3, the table leg 42 maintains a vertical support state without the action of other external forces, effectively limiting the rotational freedom of the table leg 42 during use. When the user uses the combination cabinet as a dining table, even if heavy objects are placed on it or it is subjected to external impact, the table leg 42 will not easily wobble or shift, providing stable and reliable support for the folding tabletop 3 and ensuring safety during use.

[0073] The table leg 42 rotates around the rotating shaft 54. This connection method makes the operation of the support component 4 smoother when switching between the retracted and extended states. The user only needs to lift or press down the table leg 42 to overcome the resistance of the elastic element 52 and achieve rotation. During the rotation, the cooperation between the positioning ball 53 and the limiting groove 42a can provide clear positioning feedback, making it easy for the user to quickly judge whether the table leg 42 is in place. The whole operation process is easy and efficient.

[0074] The cooperation between the elastic element 52, the positioning ball 53, and the limiting groove 42a not only achieves the positioning of the table leg 42, but also buffers the impact of external forces to a certain extent. When the table leg 42 is subjected to an accidental collision, the elastic element 52 can absorb part of the impact force, reduce damage to components such as the rotating shaft 54 ​​and the fixing element 51, extend the service life of the rotating connection assembly 5 and even the entire support assembly 4, and improve the durability and reliability of the multi-functional combination cabinet 100.

[0075] In some embodiments, combined with Figure 1 The main table body 2 has a fixed frame 6 on the side away from the tabletop. The fixed frame 6 is elastic. When the table leg 42 is stored in the storage space 21a, the second end of the table leg 42 can be locked into the fixed frame 6. The second end of the table leg 42 is the end of the table leg 42 that is in contact with the ground.

[0076] The fixing frame 6 provides accurate positioning and reliable fixation for the table leg 42 when it is in the retracted state. When the table leg 42 is engaged with the fixing frame 6, it ensures that the table leg 42 maintains a stable position within the storage space 21a, preventing it from moving arbitrarily due to shaking or collisions. This avoids noise caused by the table leg 42 wobbling within the storage space 21a or damage caused by friction or collisions with other components. The storage and retrieval of the table leg 42 are more convenient and quicker. When retracting the support component 4 back into the main table body 2, the user simply aligns the table leg 42 with the engaging position of the fixing frame 6 to easily complete the storage. When needed, the table leg 42 can be easily removed from the fixing frame 6, and the support component 4 can be adjusted to the extended position, improving user convenience and efficiency.

[0077] In some possible implementations, combined Figure 8 , Figure 8 The exploded view of the first rotating bearing 11, the rotating connecting rod 7, and the second rotating bearing 23 disclosed in the embodiments of this application shows that the multifunctional combination cabinet 100 also includes the first rotating bearing 11, the second rotating bearing 23, and the rotating connecting rod 7. The cabinet body 1 is provided with a first mounting groove, and the main table frame 21 is provided with a second mounting groove 21b. The first mounting groove and the second mounting groove 21b are in corresponding positions. The first rotating bearing 11 is disposed in the first mounting groove, and the second rotating bearing 23 is disposed in the second mounting groove 21b. The first end of the rotating connecting rod 7 is connected to the first rotating bearing 11, and the second end of the rotating connecting rod 7 is connected to the second rotating bearing 23.

[0078] The main table frame 21 can rotate smoothly around the connecting axis between the rotating connecting rod 7 and the rotating bearing. This design provides stable support and a smooth rotation mechanism for the main table 2 when switching between the use state and the storage state, ensuring that the main table 2 will not wobble or jam during rotation, thus improving the convenience and comfort of the user.

[0079] Each component can be processed and assembled separately before being assembled as a whole, improving production efficiency and product quality consistency. In later maintenance or repairs, if problems arise with the rotating connection structure, individual components can be easily replaced or repaired, reducing maintenance costs and complexity.

[0080] Optionally, cabinet 1 is equipped with a snap-fit ​​connector (not shown in the figure), and the main table frame 21 is equipped with a snap-fit ​​groove (not shown in the figure). When the main table 2 is in the storage state, the snap-fit ​​connector is located in the snap-fit ​​groove to limit the degree of freedom of the main table 2 in its own rotation direction. This can precisely limit the position of the main table 2, ensuring that the main table 2 is fixed in the storage cavity and will not shake or rotate at will. This helps protect the main table 2 and other items inside cabinet 1 from damage caused by shaking. It also makes the combination cabinet more neat in appearance and enhances the stability of the entire combination cabinet in the storage state. Even if the combination cabinet is subjected to external impact or slight vibration, the main table 2 can remain in the correct storage position and will not accidentally rotate out of the storage cavity 1a, thereby improving the reliability and durability of the combination cabinet.

[0081] Optionally, the locking component includes a locking ball and a spring. The cabinet 1 is provided with a mounting groove for placing the spring and the locking ball. The inner diameter of the mounting groove gradually decreases from the bottom of the groove to the opening of the groove, and the diameter of the opening of the mounting groove is smaller than the diameter of the locking ball, so that the locking ball is partially exposed in the opening of the mounting groove under the action of the spring. When the main table 2 is rotated to the storage state, the locking ball abuts against the groove wall of the locking groove to restrict the degree of freedom of the main table 2 in its own rotation direction. The structure is simple and the positioning effect is good.

[0082] As an optional implementation method, combined with Figure 2 and Figure 3 The main table 22 is provided with a first magnetic element 8, and the folding table 3 is provided with a second magnetic element 9. The first magnetic element 8 and the second magnetic element 9 can generate an adsorption force so that when the folding table 3 is in the folded state, the folding table 3 and the main table 22 are attracted to each other.

[0083] When the folding tabletop 3 is in the folded state, the attraction between the first magnetic component 8 and the second magnetic component 9 allows the folding tabletop 3 to be firmly attached to the main tabletop 22, effectively preventing the folding tabletop 3 from accidentally unfolding due to shaking or collision during storage, thus ensuring the stability and reliability of the stored state. Compared with other rigid fixing methods, such as clips, this adsorption fixing method causes less damage to the tabletop surface, better protects the surface integrity and aesthetics of the main tabletop 22 and the folding tabletop 3, and extends the lifespan of the tabletop.

[0084] When the tabletop 3 needs to be unfolded or folded, it can be easily operated by overcoming a small magnetic force, without complicated unlocking or fixing steps, making it more convenient and efficient to use and improving the user experience.

[0085] Optionally, the magnetic component is embedded in the tabletop, with its surface flush with the tabletop. The folding tabletop 3 can be neatly attached to the main tabletop 22, making the cabinet more regular and concise in appearance, without any extra parts or gaps, enhancing the overall aesthetics and harmony, and better meeting the modern home's pursuit of a minimalist style.
