Description

Technical Field

[0001] This utility model belongs to the field of sofa technology, and relates to a multifunctional sofa, particularly a sofa that is easy to assemble and has variable armrests. Background Technology

[0002] Sofas are a common piece of furniture in homes and offices, primarily used to provide comfortable seating and relaxation. They typically consist of a frame, seat, backrest, armrests, and cushions. Widely used in living rooms, bedrooms, offices, and other places, sofas are not only indispensable furniture in daily life but also play an important role in beautifying spaces, adding comfort, and facilitating social interaction.

[0003] Sofas typically use a one-piece structure, which makes transportation and moving inconvenient. When used in a home, especially when the sofa is large, it often gets stuck in the doorway and requires multiple people to adjust it before it can be moved in. This is time-consuming, labor-intensive, inconvenient to move, and also makes the sofa more susceptible to damage. For manufacturers, after assembly, long-distance transportation takes up a lot of space and the amount transported at one time is small, which cannot meet the needs of manufacturers to ship in large quantities. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a sofa that is easy to assemble and has variable armrests. The technical problem this utility model aims to solve is: how to make the sofa easy to disassemble, assemble, and move.

[0005] The purpose of this utility model can be achieved through the following technical solution: a sofa that is easy to assemble and has variable armrests, including a base, two back rods fixed on the upper side of the base, the back rods being connected to a back frame through a first plug-in assembly, and armrests fixed on the upper left side of the base, the armrests being connected to an armrest assembly through a second plug-in assembly.

[0006] The working principle of this utility model is as follows: the seat cushion is fixed to the base by the backrest and armrest, the back frame is connected to the backrest by the first plug-in assembly, the backrest cushion is placed on the back frame, and the armrest assembly is connected to the armrest by the second plug-in assembly. This device is easy to assemble, easy to transport and store, and highly practical.

[0007] The base includes a first base frame and a second base frame, which are connected by a connecting component.

[0008] With the above structure, the base can be disassembled and assembled.

[0009] The connecting assembly includes two connecting plates, which are located on the upper and lower sides of the connection between the first base frame and the second base frame, respectively, and are fixed together by bolts.

[0010] The above structure is simple, easy to install, low in cost, and convenient for later maintenance.

[0011] The first plug-in assembly includes a first plug-in rod, which is fixed to the upper end of the back rod. The first plug-in rod is provided with a first elastic protrusion, and the lower end of the back frame is provided with a first plug-in groove. The first plug-in groove is provided with a first positioning groove that cooperates with the first elastic protrusion.

[0012] With the above structure, when installing the back frame, align the first insertion slot with the first insertion rod so that the first insertion rod is inserted into the first insertion slot. At the same time, use the cooperation between the first elastic protrusion and the first positioning slot to position it. When disassembling, simply pull it upwards.

[0013] The handrail assembly includes a connecting frame and a handrail frame. A connecting block is fixed to the upper end of the connecting frame, and a rotating seat is fixed to the handrail frame. The rotating seat is rotatably connected to the connecting block, and a handrail plate is fixed to the handrail frame by bolts.

[0014] The above structure allows the armrest to be laid flat and used as a tabletop, or it can be erected to save space.

[0015] The second plug-in assembly includes a second plug-in rod, which is fixed to the upper end of the handrail. The second plug-in rod is provided with a second elastic protrusion, and the lower end of the connecting frame is provided with a second plug-in groove. The second plug-in groove is provided with a second positioning groove that cooperates with the second elastic protrusion.

[0016] With the above structure, when installing the handrail frame, align the second insertion slot with the second insertion rod so that the second insertion rod is inserted into the second insertion slot. At the same time, use the cooperation between the second elastic protrusion and the second positioning slot to position it. When disassembling, simply pull it upwards with force.

[0017] Compared with existing technologies, this easy-to-assemble sofa with adjustable armrests has the following advantages: 1. During installation, the first and second base frames are first connected by connecting components. The seat cushion is fixed to the base frame by the backrest and armrest. Then, the back frame is connected to the backrest by the first plug-in component. The backrest cushion is then placed on the back frame. Finally, the armrest assembly is connected to the armrest by the second plug-in component. This device is easy to assemble, convenient to transport and store, and highly practical.

[0018] 2. When installing the back frame, align the first insertion slot with the first insertion rod so that the first insertion rod is inserted into the first insertion slot. At the same time, use the cooperation between the first elastic protrusion and the first positioning slot to position it. When disassembling, simply pull it upwards.

[0019] 3. This sofa can be used with the armrests laid flat as a table, or with the armrests erected to save space, or with the armrests set at a 45° angle for reclining and support.

[0020] 4. When installing the handrail frame, align the second connector slot with the second connector rod so that the second connector rod is inserted into the second connector slot. At the same time, use the cooperation between the second elastic protrusion and the second positioning slot to position it. When disassembling, simply pull it upwards. Attached Figure Description

[0037] With the above structure, when installing the handrail frame 8, the second insertion slot is aligned with the second insertion rod 10, so that the second insertion rod 10 is inserted into the second insertion slot. At the same time, the second elastic protrusion 12 is used to position it by cooperating with the second positioning slot. When disassembling, it can be pulled upwards with force.

[0038] The working principle of this utility model is as follows: During installation, the two connecting plates 15 are located on the upper and lower sides of the connection between the first base frame 2 and the second base frame 1, respectively. The first base frame 2 and the second base frame 1 are connected by bolts. The seat cushion is fixed to the base frame by the backrest 3 and the armrest 5. Then, the first insertion slot is aligned with the first insertion rod 9, so that the first insertion rod 9 is inserted into the first insertion slot. At the same time, the first elastic protrusion 11 is positioned by cooperating with the first positioning groove, thereby connecting the back frame 4 with the backrest 3. The backrest cushion is placed on the back frame 4. The second insertion slot is aligned with the second insertion rod 10, so that the second insertion rod 10 is inserted into the second insertion slot. At the same time, the second elastic protrusion 12 is positioned by cooperating with the second positioning groove, thereby connecting the armrest assembly with the armrest 5. This device is easy to assemble, easy to transport and store, and highly practical. It is not only easy to move into the home, but also reduces space during factory transportation, making it convenient for bulk shipment.
