[0036] In this embodiment, when assembling the improved upholstered sofa's solid wood frame, please refer to... Figure 1 , Figure 5 and Figure 6 As shown, the operator first connects the two side rails 3 to the back plate 6 using the constraint mechanism 7, and then please refer to... Figure 1 and Figure 2 As shown, the connection and fixation between the base plate 1, the two side panels 3 and the back panel 6 are completed by the connecting mechanism 4, so that the base plate 1, the support legs 2, the two side panels 3 and the back panel 6 form a complete solid wood frame for the upholstered sofa. Then, according to the existing assembly of the upholstered cushions and the solid wood frame of the upholstered sofa, the cushions are fixed on the solid wood frame of the upholstered sofa, and the assembly of the upholstered sofa is completed.

[0037] When disassembling the improved solid wood frame of the upholstered sofa, the operator first disconnects the side panel 3 from the base plate 1 through the connecting mechanism 4, then moves the two side panels 3 upwards, and can directly remove the two side panels 3 and the back plate 6 from the base plate 1. Finally, the side panels are pulled away from the back plate 6 to disconnect the connection between the side panels and the back plate 6, and the disassembly of the solid wood frame of the upholstered sofa is completed. The disassembly and assembly of the device is simple.

[0038] After the improved solid wood frame of the upholstered sofa is disassembled, the operator places the upholstered sofa cushions between several support legs 2 and the base plate 1. Then, the connection between the two side panels 3 and the back panel 6 is completed through the constraint mechanism 7. Next, the side panels 3 are inserted between the support legs 2. Finally, the connection between the support legs 2 and the side panels 3 is completed through the cooperation of the connecting mechanism 4 and the connector 5. At this time, the base plate 1, support legs 2, two side panels 3 and back panel 6 form a structure similar to a storage box for storing the upholstered sofa cushions. The cushions can be packaged and shipped together with the solid wood frame. The rectangular structure facilitates the packaging of the upholstered sofa and greatly reduces the space occupied during shipping, thus improving the transportation efficiency of the upholstered sofa.

[0039] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the base plate 1 includes an outer frame 11 and several horizontal bars 12. The several horizontal bars 12 are fixedly installed at equal intervals inside the outer frame 11, and the upper and lower sides of each horizontal bar 12 are coplanar with the upper and lower sides of the outer frame 11, respectively.

[0040] In this embodiment, please Figure 1 and Figure 2 As shown, the base plate 1, which consists of an outer frame 11 and several crossbars 12, effectively reduces the overall weight of the base plate 1 while maintaining its supporting strength, and allows the soft pad placed on the base plate 1 to have full contact with the outside air.

[0041] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, the connecting mechanism 4 includes several studs 41, which are disposed opposite to the corresponding side blocks 3. The bottom end of the stud 41 passes through the bottom side plate wall and the outer frame 11 of the corresponding side block 3 and is threaded with a nut 42. The top side of the stud 41 is coplanar with the inner bottom wall of the corresponding side block 3.

[0042] In this embodiment, please refer to Figure 2 and Figure 3 As shown, after the side guard 3 is placed on the base plate 1, the operator locks the position between the side guard 3 and the base plate 1 by the cooperation of the stud 41 and the nut 42, making the assembly operation between the side guard 3 and the base plate 1 relatively convenient.

[0043] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a sleeve 43 is fixedly installed inside the side block 3 at the position corresponding to the nut 42, and the sleeve 43 is threaded onto the outer periphery of the corresponding stud 41.

[0044] A sleeve 44 is fixedly installed inside the plate wall of the outer frame 11, and the sleeve 44 is threaded onto the outer periphery of the corresponding stud 41.

[0045] In this embodiment, please refer to Figure 2 and Figure 3 As shown, when assembling the side guard 3 and the base plate 1, the operator uses a hex wrench to turn the stud 41 so that the stud 41 passes through the inner hole of the first sleeve 43 and the second sleeve 44. Then, the nut 42 is screwed on the bottom end of the stud 41 to complete the assembly of the side guard 3 and the base plate 1. The operation is relatively convenient. Moreover, the first sleeve 43 and the second sleeve 44 can enhance the strength of the side guard 3 and the base plate 1 in some parts, so that the connection structure between the side guard 3 and the base plate 1 can withstand greater force.

[0046] It should be noted that the internal threads of sleeve 43 and sleeve 44 are in the same direction, while the internal thread of nut 42 is opposite to that of sleeve 43. This forms a self-locking structure after the side stop 3 and the base plate 1 are assembled, making the assembly of the side stop 3 and the base plate 1 more stable.

[0047] In a further preferred embodiment of this utility model, such as Figures 1-4 As shown, the connector 5 includes two mounting holes 51, which are opened on the corresponding support leg 2. An internally threaded tube 52 is fixedly installed in the mounting hole 51, and the end of the internally threaded tube 52 near the opening of the corresponding mounting hole 51 is coplanar with the side wall of the corresponding support leg 2.

[0048] In this embodiment, please refer to Figures 1-4 As shown, after the side block 3 is inserted between the two support legs 2, the stud 41 is turned so that it passes through the sleeve 43. Then the stud 41 is screwed into the threaded tube, which completes the connection and fixation between the side block 3 and the support legs 2. The operation is relatively simple.

[0049] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the constraint mechanism 7 includes several square tubes 71, which are divided into two groups and fixedly installed in the two side blocks 3 at equal intervals. Several support rods 72 are fixedly installed through the back plate 6 at equal intervals, and both ends of each support rod 72 are arc-shaped. The two ends of the support rod 72 are inserted into the corresponding square tube 71 and contact the inner wall of the corresponding square tube 71.

[0050] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, when assembling the side panels 3 and the back plate 6, the operator inserts the two ends of the support rod 72 into the corresponding square tubes 71 on the two side panels 3 respectively. At this time, due to the fit between the outer wall of the end of the support rod 72 and the inner wall of the square tube 71, a frictional force is generated between the side panel 3 and the back plate 6 to temporarily limit and fix the side panel 3 and the back plate 6. In addition, the arc surface setting at both ends of the support rod 72 reduces the area at both ends of the support rod 72, making it easier to insert the two ends of the support rod 72 into the square tube 71.

[0051] After the connection and fixation between the side guard 3 and the base plate 1 are completed, the back plate 6 can be supported by multiple positions of the back plate 6 due to the mutual contact between the support rod 72, the back plate 6 and the square tube 71, so as to enhance the stability of the connection between the back plate 6 and the floor.

[0052] After the connection and fixation between the side plate and the support leg 2 are completed, the support rod 72, the back plate 6 and the square tube 71 can be constrained and fixed between the two side blocks 3 due to the mutual contact between them. This allows the back plate 6 to block the openings in the space between the four support legs 2, the two side blocks 3 and the base plate 1.

[0053] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a number of limiting rods 73 are fixedly installed at equal intervals on the bottom side of the back plate 6. A limiting groove 74 is opened on the top side of the outer frame 11 at the position corresponding to the limiting rod 73. The bottom end of the limiting rod 73 is arc-shaped and inserted into the corresponding limiting groove 74.

[0054] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, during the process of placing the back panel 6 and the side panel 3 on the top side of the base plate 1, the limiting rod 73 is simultaneously inserted into the limiting groove 74. After the solid wood frame of the upholstered sofa is assembled, the mutual contact between the limiting rod 73 and the inner wall of the limiting groove 74 can enhance the connection strength between the back panel 6 and the base plate 1.

[0055] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
