Description

Technical Field

[0001] This invention relates to the field of rattan sofa technology, specifically to a rattan modular sofa support frame structure and its preparation method. Background Technology

[0002] Rattan sofas are loved for their elegant colors, beautiful shapes, and lightweight structure. They symbolize closeness to nature, simplicity yet luxury, and are a symbol of leisurely living. Currently, the main support frame (seat panel) of rattan sofas is often a fixed structure, dividing the seating area into fixed-size sections. While this structure is simple, easy to manufacture, and ensures the aesthetic appeal of the rattan sofa, it also results in poor adjustability. It's impossible to adjust the size of the seating area according to actual needs. For example, dividing a three-seater sofa into three fixed-size areas will inevitably be unsuitable for people of different body types. On the other hand, if the entire seat panel is integrated, privacy is compromised, making it unsuitable for public places. Therefore, many people choose sofas with separate seating areas when purchasing them.

[0003] Based on this, we propose a rattan-woven modular sofa support frame structure and its preparation method. Summary of the Invention

[0040] Example 1:

[0041] Please see Figures 1-3 A rattan modular sofa support frame structure includes a seat frame 1, on which an inner groove 2 is formed, such as... Figure 1 As shown, several control cabinets 3 are arranged longitudinally and fixedly installed on the inner side wall of the base frame 1. Several partition rods 9 are slidably arranged at the top opening of the inner groove 2. The partition rods 9 are connected to the control cabinets 3 through a connecting mechanism. A driving mechanism is provided inside the control cabinets 3. The driving mechanism can drive the connecting mechanism and the partition rods 9 to move left and right.

[0042] In this embodiment, the control cabinets 3 are at different heights, while multiple partition rods 9 are located on the same horizontal plane, and each control cabinet 3 controls one partition rod 9.

[0043] like Figure 3 As shown, the drive mechanism includes a lead screw 4 and a lead screw 6. The control cabinet 3 has a drive cavity inside, and the lead screw 4 is rotatably disposed in the drive cavity. One end of the lead screw 4 is rotatably disposed on the inner wall of the drive cavity, and the other end extends to the outside of the control cabinet 3 and has a groove 5 at the end. The lead screw 4 is threadedly connected to the outer wall of the lead screw 6. In this embodiment, the connection mechanism includes a connecting rod 8 and a support plate 7. The partition rod 9 is connected to the support plate 7 through the connecting rod 8, and the support plate 7 is fixedly installed on the lead screw 6.

[0044] By controlling the rotation of the lead screw 4, the threaded nut 6 on its outer wall can move left and right. The left and right movement of the threaded nut 6 can drive the partition rod 9 to move left and right through the support plate 7 and the connecting rod 8.

[0045] Because the control cabinet 3 has a stepped height difference, the connecting rods 8 can be set to different lengths to ensure that all the partition rods 9 are on the same horizontal plane.

[0046] In this embodiment, a first slider 10 is fixedly installed at one end of the separator rod 9, and the first slider 10 is slidably disposed in the first groove 11. A second slider 12 is fixedly installed at the other end of the separator rod 9, and the second slider 12 is slidably disposed in the second groove 13. The first groove 11 and the second groove 13 are respectively opened on the inner walls of the inner groove 2 on both sides. By setting the first slider 10 and the second slider 12, the left and right movement of the separator rod 9 can be made more stable and smooth.

[0047] In this embodiment, the seat frame 1 is divided into sections by multiple dividing rods 9. Each dividing rod 9 can be driven by a lead screw 4 to adjust its position, thereby allowing the size of each seating area to be freely adjusted according to usage needs, so as to meet the usage needs of different people and greatly improve the functionality and practicality of the rattan sofa.

[0048] Example 2:

[0049] Please see Figures 4-7 Based on Embodiment 1, in this embodiment, the outer wall of the separator rod 9 is wrapped with an annular airbag 14, and the annular airbag 14 and the separator rod 9 are connected by a connecting groove 15.

[0050] When the ring-shaped airbag 14 is inflated, it can not only cushion the divider bar 9 and improve the comfort of the seat area, but also support the rattan and keep it taut, thus avoiding the problem of the rattan becoming loose and affecting the appearance of the rattan sofa after a long period of use.

[0051] In this embodiment, the seat frame 1 can be hollow, and the seating area can be divided by the divider rod 9, which reduces the use of materials and lowers the cost. At the same time, the divider rod 9 also ensures the support of the rattan, effectively supporting the user's body.

[0052] like Figure 4 and Figure 5 As shown, the second slider 12 has a telescopic groove 16, and a locking post 17 is movably telescopically installed in the telescopic groove 16. The outer wall of the locking post 17 forms a conical slope 19, and the inner wall of the telescopic groove 16 forms a conical groove 18 coupled with the conical slope 19. The locking post 17 is connected to the positioning plate 21 by a spring 20. The positioning plate 21 is fixedly installed in the partition rod 9 by a fixing rod 22. The end of the locking post 17 is movably locked between two adjacent positioning posts 23. The positioning posts 23 are evenly fixedly installed on the inner side wall of the second slide groove 13.

[0053] In the normal state (when the end of the locking post 17 is locked between two adjacent positioning posts 23), the locking post 17 is lifted by the spring 20, and the conical slope 19 is tightly attached to the conical groove 18, sealing the telescopic groove 16. At this time, the gas in the separator rod 9 cannot be discharged.

[0054] When the drive separator 9 moves, the end of the locking post 17 will disengage from the two adjacent positioning posts 23 and be lifted up by the positioning posts 23. While the locking post 17 is lifted up and compresses the spring 20, the conical slope 19 will also disengage from the conical groove 18. After the two disengage, the air in the separator 9 can be discharged through the gap between them, achieving the effect of venting.

[0055] Therefore, when the separator rod 9 is in a stable state, the gas inside it will not be released, which can support the annular airbag 14 and thus support the rattan; when the separator rod 9 moves, the locking post 17 will be pushed in the initial stage of the movement to quickly release the air inside the separator rod 9 and achieve the effect of venting.

[0056] By releasing air from the separator rod 9 and the annular airbag 14, the support for the rattan can be released, thus facilitating the movement and adjustment of the separator rod 9.

[0057] In this embodiment, after the separator rod 9 is adjusted to a suitable position, it can be inflated. The specific inflation structure is as follows:

[0058] The control cabinet 3 also has an air chamber 24 inside, and a piston 25 is movably installed in the air chamber 24. A push rod 26 is fixedly installed on the piston 25. The end of the push rod 26 extends to the outside of the control cabinet 3 and is fixedly connected to a handle 27. The air chamber 24 is connected to the partition rod 9 through an air supply pipe 28. A one-way air outlet valve is installed on the air supply pipe 28. The air chamber 24 is also connected to an air inlet pipe, and a one-way air inlet valve is installed on the air inlet pipe.

[0059] By pulling the push rod 26 and piston 25 with the handle 27, external air will enter the air chamber 24. Conversely, by pushing the piston 25, air will enter the separator rod 9 through the air supply pipe 28, achieving the effect of inflation, so as to make the annular airbag 14 inflate again.

[0060] Example 3:

[0061] Please see Figures 1-7 This embodiment provides a method for preparing a rattan-woven modular sofa support frame structure, specifically including the following steps:

[0062] S1. Install the control cabinet 3 in the inner groove 2 from bottom to top in descending order of the length of the connecting rod 8, and make the first slider 10 and the second slider 12 at both ends of the separator 9 respectively stuck in the first slide groove 11 and the second slide groove 13.

[0063] S2. Weave rattan around the seat frame 1;

[0064] S3. Inflate the annular airbag 14 with air to make it inflate and support the rattan.
