[0034] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0035] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0036] Reference Figures 1 to 6 As shown, this embodiment of the utility model provides a sofa, including a connecting rod 1 and upholstered units 2. Several upholstered units 2 are arranged and stacked sequentially along the axial direction of the connecting rod 1; at least one upholstered unit 2 has an embedded shaft assembly 3, which is rotatably connected to the connecting rod 1; when the sofa is in use, the connecting rod 1 is in a vertical position. It should be noted that the upholstered unit 2, as an existing structure, can be referenced to the structure of the sofa cushion and seat panel. The interior of the upholstered unit 2 is typically filled with soft and elastic materials, such as sponge, down, or latex. The upholstered unit 2 also has an outer fabric covering the filling material, serving a protective and decorative function. Common fabrics include leather (such as top-grain cowhide, artificial leather), fabrics (such as cotton, linen, or velvet), etc. Additionally, one or more layers of thin plywood, thin wooden blocks, or wooden frames can be added inside the upholstered unit to increase its support; this supportive structural design is also a common implementation method for upholstered units in the prior art.

[0037] In this embodiment, the user can operate the upholstered units 2 according to their own needs. On the one hand, they can adjust the stacking order of the upholstered units 2 along the axial direction of the connecting rod 1; on the other hand, they can rotate the upholstered units 2 with the shaft kit 3 around the connecting rod 1. By combining these two operation methods, multiple upholstered units 2 can be combined into different configurations, thereby changing the overall shape of the sofa.

[0038] Therefore, users can freely adjust the stacking order and rotation angle of the upholstered units 2 according to their preferred posture or usage needs such as sitting, lying down, or leaning, creating a wide variety of sofa shapes. This satisfies the personalized needs of different users for sofa shapes and can adapt to different usage scenarios and spatial layouts, making it more adaptable and innovative than traditional fixed-shape sofas.

[0039] In addition, unlike existing deformable sofas that rely on complex mechanical structures or additional accessories to adjust their shape, this sofa only requires simple adjustment of the stacking order of the upholstery units 2 and rotation, making the operation convenient and quick.

[0040] Furthermore, the multiple soft-pack units 2 are independently designed, allowing them to be disassembled for transportation and storage, significantly reducing the overall volume and space occupied. This not only lowers logistics and transportation costs but also facilitates storage in warehouses and other locations, improving space utilization. Figure 7 and Figure 8 This is a schematic diagram of the transportation status.

[0041] In some practical applications, several soft-pack units 2 are of different sizes; the largest soft-pack unit 2 is located at the bottom of the connecting rod 1, the smallest soft-pack unit 2 is located at the top of the connecting rod 1, and the remaining soft-pack units 2 are sequentially fitted onto the connecting rod 1 from largest to smallest, each located between the largest and smallest soft-pack unit 2. In practical applications, at least one soft-pack unit 2 has a concave arc-shaped structure 23 on its side, which can provide good support for the user's lower back and provide comfort.

[0042] During use, users can still rotate each upholstered unit 2 with the shaft assembly 3 around the connecting rod 1 to change the local shape of the sofa. Simultaneously, because the upholstered units 2 are of different sizes and stacked in an orderly manner, users can more intuitively adjust the stacking order based on the size differences; the largest upholstered unit 2 is located at the bottom, providing a more stable support base for the entire sofa. This bottom-large, top-small structural design conforms to mechanical principles, making the sofa more stable during use and less prone to tipping or wobbling. Moreover, this design makes it easier for users to recline on the sofa and sit directly on the next larger upholstered unit 2.

[0043] In some practical applications, the connection between the soft-pack unit 2 and the connecting rod 1 has at least the following two connection methods:

[0044] The first connection method involves several upholstered units 2 rotatably connected to the connecting rod 1 via corresponding shaft fittings 3, meaning all upholstered units 2 can rotate on the connecting rod 1. In this connection method, all upholstered units 2 are rotatably connected to the connecting rod 1 via shaft fittings 3. Users can independently rotate each upholstered unit 2 according to their needs. Because each upholstered unit 2 can rotate freely, users can flexibly adjust the angles of each upholstered unit 2, thereby creating a variety of sofa design combinations. For example, adjacent upholstered units 2 can be rotated to different angles to form a wave-like shape, greatly enriching the sofa's appearance and usability.

[0045] The second connection method is based on the stacking of several soft-pack units 2 according to their size in the above embodiment: the remaining soft-pack units 2 and the largest soft-pack unit 2 are rotatably fitted onto the connecting rod 1 through corresponding shaft fittings 3, and the smallest soft-pack unit 2 is threadedly connected to the threaded end 11 at the top of the connecting rod 1 through its internally embedded internal threaded part 21. In this connection method, except for the smallest soft-pack unit 2, the remaining soft-pack units 2 and the largest soft-pack unit 2 are rotatably fitted onto the connecting rod 1 through shaft fittings 3. These rotatable soft-pack units 2 can be angled as in the first connection method. The smallest soft-pack unit 2 is threadedly connected to the threaded end 11 at the top of the connecting rod 1 through its internally embedded internal threaded part 21. This connection method allows the smallest soft-pack unit 2 to be fixed at the top of the connecting rod 1 under normal conditions, playing a role in stabilizing the overall structure and decorating the top.

[0046] Therefore, in the first connection method, all upholstered units 2 can rotate, providing a variety of endless styling possibilities. Users can change the shape of the sofa according to different occasions and home styles. The second connection method strikes a balance between overall structural stability and flexibility: the smallest upholstered unit 2 is fixed to the top via a threaded connection, providing a certain degree of stability to the sofa as a whole and preventing the sofa structure from becoming too loose when adjusting other upholstered units 2. At the same time, the other rotatable upholstered units 2 can still meet the user's needs for styling changes, achieving a good combination of stability and flexibility.

[0047] In some practical applications, based on any of the above embodiments, the connection method between the shaft assembly 3 and the corresponding sofa upholstery is structurally designed as follows: each shaft assembly 3 has a flange 31 at both ends, and each upholstery unit 2 has an insertion hole 22. The shaft assembly 3 is embedded into the insertion hole 22 on the corresponding upholstery unit 2, and the two flanges 31 are used to axially limit the upholstery unit 2 relative to the shaft assembly 3. It should be noted that this connection method is completed in the factory processing stage. When the user assembles the sofa, they only need to put the shaft assembly 3 (generally made of high-strength recycled plastic material in the factory) on the upholstery unit 2 onto the connecting rod 1.

[0048] In some practical applications, a load-bearing plate 4 is installed at the bottom of the soft-pack unit 2 at the lowest end of the connecting rod 1. This load-bearing plate 4 can also be directly mounted on the shaft assembly 3 on the soft-pack unit 2. The connecting rod 1 is inserted into the shaft assembly 3 in the lowest soft-pack unit 2 and abuts against the load-bearing plate 4. When the connecting rod 1 is inserted into the shaft assembly 3 of the lowest soft-pack unit 2 and abuts against the load-bearing plate 4, the load-bearing plate 4 serves to absorb and distribute pressure, thus ensuring the stability of the connecting rod 1 and the soft-pack unit 2.

[0049] In addition, the bottom of the soft-pack unit 2 at the lowest end of the connecting rod 1 is threaded with several feet 5 to support the entire sofa structure.

[0050] In summary, this sofa can be designed in a variety of different styles for users to choose from; for example... Figures 9 to 14 As shown, this provides some common usage methods and the usage status of the sofa.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
