Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figures 1-5 As shown, a modular sofa includes a rear support leg 1, which serves as the core support component. The inclined structure at the bottom of the rear support leg enhances stability upon landing. The first connector 101, the locking block 103, and the second connector 102 on its surface are arranged in a spatially orthogonal or reversed layout (the first connector 101 and the second connector 102 extend in opposite directions, and the locking block 103 is perpendicular to both). This layout enables multi-directional, non-interfering connection interfaces, laying the foundation for the centralized connection of multiple components.

[0019] During assembly, firstly, the two rear support legs 1 are connected to the corresponding front support legs 2 via their second connectors 102. The tilt direction of the front support legs 2 is opposite to that of the rear support legs 1, and the two together form a stable base frame with good resistance to forward and backward tipping. Next, the back support 4 is connected and fixed to the first connector 101 of the rear support legs 1 via its bottom interface.

[0020] One end of the armrest 3 is connected to the side of the back support 4 via the fourth connector 401, while the other end is connected to the hook-shaped structure at the top of the rear support leg 1 via the third connector 104. Thus, the armrest 3, the rear support leg 1, and the back support 4 form a robust triangular support structure. This triangular structure possesses excellent mechanical stability, effectively withstanding lateral forces and pressures during use, greatly enhancing the overall rigidity of the sofa structure.

[0021] The fifth connector 402 at the top of the backrest support 4 is used to connect to the top support 5, providing contour support for the upper edge of the backrest. The sixth connector 403 at the lower part of the backrest support 4 is used to connect to the rear support rod 6, which is one of the main support components at the rear of the seat cushion.

[0022] The side support rod 7 is a key component for connecting the side and front. One end is connected to the front support 8 via a seventh connector 701, and the other end is connected to the protruding rod 404 on the back support 4 via an eighth connector 702. Simultaneously, the middle or a specific part of the side support rod 7 engages with the locking block 103 on the rear support leg 1. In a preferred embodiment, the locking block 103 is a semi-circular elastic locking structure, allowing the side support rod 7 to be easily "locked in" or "pulled out," ensuring a tight connection while enabling quick assembly and disassembly without tools, perfectly demonstrating the convenience of modular design. Ultimately, the two side support rods 7, one rear support rod 6, and one front support 8 together form a complete rectangular seat frame, providing stable support for the seat cushion.

[0023] How it works: When transportation or long-term storage is required, users or logistics personnel can easily disassemble the sofa into multiple linear components by reversing the connection process described above. These components are regularly shaped and can be stacked tightly or packed side by side. Compared with traditional one-piece sofas, this significantly reduces transportation volume, logistics costs, and storage space requirements.

[0024] During use, if a component of the sofa (such as the rear support rod 6, which is subjected to constant pressure, or the back support 4, which is frequently leaned against) is accidentally damaged or worn out, the damaged component can be removed and replaced simply by disassembling the connecting parts associated with that component (such as the sixth connecting part 403). For example, when replacing the rear support rod 6, it is completely unnecessary to touch the main support structure (rear legs 1, back support 4) and other frames. This "targeted repair" method avoids the situation where local damage leads to the scrapping of the entire sofa, greatly extending the overall lifespan of the product and saving users money.

[0025] In summary, this utility model, through a series of robust and ingenious connection structures (such as triangular supports, multi-directional connectors, and elastic buckles), tightly and reliably combines various modular components into a whole, ensuring the stability and safety of the sofa during use. At the same time, this design allows the sofa to be quickly disassembled into easily transportable independent modules, or for partial component replacement, achieving cost savings and optimized space efficiency throughout its entire lifecycle from manufacturing and distribution to use.
