DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 7 The seat cushion 4 is fixedly mounted on the first connecting plate 3 and the seat frame 1, and a connecting assembly is provided between the first connecting plate 3 and the base frame 1, and a back cushion 5 is provided on the base frame 1, and a second connecting plate 6 is fixedly mounted on the back cushion 5. An L-shaped connecting rod 7 is symmetrically fixedly mounted on the side of the second connecting plate 6 away from the back cushion 5. Slots are symmetrically opened at the upper end of the base frame 1, and one end of the two connecting rods 7 is vertically inserted into the two slots respectively. A plurality of positioning holes 13 penetrating the rectangular groove 2 are opened on the side of the base frame 1, and a plurality of connecting holes 14 are opened on the side of the first connecting plate 3, which are respectively connected to the plurality of positioning holes 13. The connecting assembly includes a plurality of positioning rods 8 and a strip rod 9 fixedly mounted on one end of the plurality of positioning rods 8. The plurality of positioning rods 8 respectively pass through the plurality of positioning holes 13 and are inserted into the plurality of connecting holes 14. Both ends of the strip rod 9 are provided with a locking assembly for locking the strip rod 9.

[0026] The base frame 1, seat cushion 4 and back cushion 5 of the sofa are designed in a modular manner. The first connecting plate 3 on the seat cushion 4 is inserted into the rectangular groove 2 opened on the base frame 1. The multiple positioning rods 8 on the strip rod 9 are respectively passed through the multiple positioning holes 13 and then inserted into the multiple connecting holes 14. The first connecting plate 3 is connected to the base frame 1 through the multiple positioning rods 8, thereby completing the installation of the seat cushion 4. Then, the two connecting rods 7 on the second connecting plate 6 are placed above the two slots opened in the base frame 1, and the connecting rods 7 are moved downward and inserted into the two slots, thereby installing the second connecting plate 6 on the base frame 1 and completing the installation of the back cushion 5. It adopts a simple connection structure and is easy to disassemble and install, thereby reducing the space occupied during transportation and reducing transportation costs. At the same time, when the sofa is damaged, the damaged parts can be disassembled and repaired, reducing the maintenance cost of the sofa.

[0027] A mounting groove is provided at one end of the strip rod 9, and the locking assembly includes a limit block 11 slidably installed in the mounting groove through a telescopic spring 10 and a clamping block 12 fixedly installed on the base frame 1. A limit hole is provided on the clamping block 12, and one end of the limit block 11 is inserted into the limit hole.

[0028] When the multiple positioning rods 8 are fully inserted into the positioning holes 13 and the connecting holes 14, one end of the limit block 11 is inserted into the limit hole opened by the clamping block 12. Under the action of the elastic force of the telescopic spring 10, the limit block 11 tends to move toward the clamping block 12, thereby locking the strip rod 9 on the base frame 1, preventing the base frame 1 and the first connecting plate 3 from loosening during use of the sofa.

[0029] The base frame 1 is symmetrically provided with connecting holes 15, and the base frame 1 is provided with a splicing assembly for connecting two base frames 1, the splicing assembly includes a U-shaped connecting frame 16 and a U-shaped clamping block 17, both ends of the connecting frame 16 are provided with a groove, the two ends of the clamping block 17 are respectively inserted into the two grooves, and the two ends of the connecting frame 16 are respectively inserted into the two connecting holes 15 opened in the two adjacent base frames 1.

[0030] When multiple sofas need to be spliced ​​together, multiple base frames 1 are neatly placed together, and then the two ends of the connecting frame 16 are respectively inserted into the connecting holes 15 opened in the two adjacent base frames 1 to connect the two base frames 1 together. Then, the clamping block 17 is clamped into the groove opened at one end of the connecting frame 16 to prevent the connecting frame 16 from moving out of the two connecting holes 15. After multiple sofas are spliced ​​together, the overall length of the sofa can be changed to accommodate more people. The sofas can be spliced ​​according to actual usage conditions, effectively improving the practicality of the sofas.

[0031] The width of the seat cushion 4 is greater than the width of the base frame 1, and the width of the back cushion 5 is the same as the width of the seat cushion 4. When the two base frames 1 are spliced ​​together, the two seat cushions 4 can be tightly fitted together, the gap between the two seat cushions 4 can be reduced, and the comfort of using the sofa can be ensured.

[0032] In the present invention, the base frame 1, seat cushion 4 and back cushion 5 of the sofa are modularly designed, the first connecting plate 3 on the seat cushion 4 is inserted into the rectangular groove 2 opened on the base frame 1, the multiple positioning rods 8 on the strip rod 9 are respectively passed through the multiple positioning holes 13, and then inserted into the multiple connecting holes 14, the first connecting plate 3 is connected to the base frame 1 through the multiple positioning rods 8, thereby completing the installation of the seat cushion 4, and then the two connecting rods 7 on the second connecting plate 6 are placed above the two slots opened in the base frame 1, the connecting rods 7 are moved downward and inserted into the two slots, thereby installing the second connecting plate 6 on the base frame 1, completing the installation of the back cushion 5, adopting a simple connection structure, easy to disassemble and install, thereby reducing the space occupied during transportation and reducing transportation costs. At the same time, when the sofa is damaged, the damaged parts can be disassembled and repaired, reducing the maintenance cost of the sofa.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
