Description

Technical Field

[0001] This invention relates to the field of rattan sofa technology, specifically to a rattan modular sofa connection structure and a rattan modular sofa. 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, rattan sofas are often of a fixed structure, woven in one piece, resulting in a beautiful appearance. While this ensures the aesthetic appeal of the rattan sofa, it also limits its expandability, making it impossible to adjust the size (single, double, or multi-seater) to suit actual needs.

[0003] In the Chinese patent announcement number CN205338302U, a rattan sectional sofa is provided, which is composed of multiple sofa units that can be used individually. Every two sofa units are connected by a connecting piece and two screws.

[0004] While the aforementioned rattan sectional sofas can be used individually or in combination, in practical applications we have found that there are still areas for improvement, such as:

[0005] When used alone, the aforementioned rattan sectional sofas lack armrests on both sides, severely impacting the user experience. However, installing armrests would make it inconvenient to disassemble and assemble the sofa.

[0006] Based on this, we propose a rattan modular sofa connection structure and a rattan modular sofa. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides a rattan modular sofa connection structure and a rattan modular sofa, which has the advantages of being aesthetically pleasing and capable of being freely combined or used individually.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a rattan modular sofa connection structure, which has the following beneficial effects:

[0025] 1. The connecting structure of this rattan modular sofa is such that the locking post in the first slot can be inserted into the first slot on the connecting rod, thus fixing one end of the connecting rod in the first slot; the locking post in the second slot can be inserted into the second slot on the connecting rod, thus fixing the other end of the connecting rod in the second slot; thus, the seat board and the armrest board can be connected through the connecting rod, which is simple in structure and stable in connection.

[0026] 2. The rattan modular sofa connection structure allows for the connection of two adjacent seat panels to be extended when the sofa needs to be expanded. It can be freely combined according to actual needs. Finally, the armrest can be connected to the side of the outermost seat panel through the connecting rod. This ensures the normal function and shape of the sofa, while also allowing for free expansion and combination of the sofa.

[0027] 3. The connecting structure of this rattan modular sofa only requires the installation of a rotating disc or other mechanism inside the seat or armrest, without altering the appearance of the rattan sofa, thus not affecting the normal rattan weaving process. Moreover, since the seat and armrest are no longer integrated into one rattan weaving, the rattan weaving process is greatly simplified, as the seat and armrest can be woven separately.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see Figures 1-8 A rattan modular sofa connection structure includes a seat board 1 and an armrest board 2 connected by a connecting rod 3. Specifically, as shown in... Figure 3 As shown, a first slot 6 and a second slot 17 for inserting the connecting rod 3 are respectively provided on the support plate 2 and the seat plate 1. The inner walls of the first slot 6 and the second slot 17 are movably and telescopically provided with locking posts 10, while the outer walls of both ends of the connecting rod 3 are respectively provided with a first slot 4 and a second slot 5 for locking the locking posts 10.

[0040] The locking pin 10 in the first slot 6 can be engaged with the first slot 4 on the connecting rod 3, thus fixing one end of the connecting rod 3 in the first slot 6; the locking pin 10 in the second slot 17 can be engaged with the second slot 5 on the connecting rod 3, thus fixing the other end of the connecting rod 3 in the second slot 17; thus, the seat plate 1 and the armrest plate 2 can be connected through the connecting rod 3, which has a simple structure and stable connection.

[0041] When the sofa needs to be extended, two adjacent seat boards 1 can be connected by connecting rod 3 to extend the length of the sofa. It can be freely combined according to actual needs. Finally, the armrest board 2 can be connected to the side of the outermost seat board 1 by connecting rod 3. This not only ensures the normal function and shape of the sofa, but also allows for free expansion and combination of the sofa, improving the usage effect.

[0042] The connection structure provided by this invention does not require any changes to the appearance of the rattan sofa, and therefore does not affect the normal rattan weaving process. Moreover, since the seat board 1 and the armrest board 2 are no longer integrated into one rattan weaving, the rattan weaving process is greatly simplified, and the seat board 1 and the armrest board 2 can be rattan woven separately.

[0043] like Figures 4-6 As shown, annular cavities 7 are formed around the first slot 6 and the second slot 17. Several movable rods 8 are movably arranged in the annular cavity 7. The locking pin 10 is fixedly installed on the movable rods 8. Thus, by controlling the movement of the movable rods 8, the extension of the locking pin 10 can be controlled.

[0044] In this embodiment, multiple locking posts 10 are provided in both the first slot 6 and the second slot 17, while the first slot 4 and the second slot 5 are both annular slots. By inserting multiple locking posts 10 into the annular slots, the connecting rod 3 can be effectively positioned.

[0045] like Figure 5 As shown, a limiting rod 9 is also inserted inside the moving rod 8. Both ends of the limiting rod 9 are fixedly installed on the inner wall of the annular cavity 7. By inserting the limiting rod 9 inside the moving rod 8, the movement of the moving rod 8 within the annular cavity 7 can be made more stable.

[0046] like Figure 6 As shown, the end of the moving rod 8 is slidably disposed in the arc-shaped groove 11. The arc-shaped groove 11 is evenly opened on the rotating disk 12. The rotating disk 12 is rotatably disposed in the disk cavity 13. The disk cavity 13 is connected to the annular cavity 7. Thus, the rotating disk 12 is driven to rotate. Through the guidance of the moving rod 8 by the arc-shaped groove 11, it can be driven to move, thereby causing the locking pin 10 to extend out and lock into the locking groove.

[0047] In this embodiment, a drive column 14 is fixedly installed at the center of the rotating disk 12 inside the support plate 2. The end of the drive column 14 extends to the outside of the support plate 2, and the rotating disk 12 can be directly driven by the drive column 14.

[0048] like Figure 2 As shown, a hook plate 16 is fixedly installed at the end of the drive column 14, and a wire ring with a buckle 15 is detachably installed on the hook plate 16. The buckle 15 is fixedly installed on the support plate 2.

[0049] When the drive column 14 rotates to the position and the locking column 10 is locked in the slot, the hook piece 16 is in a vertical position. At this time, it can be effectively positioned by the buckle 15, thereby preventing the drive column 14 from rotating.

[0050] To rotate the drive column 14, simply unlock the latch 15.

[0051] Therefore, in this embodiment, when it is necessary to connect the connecting rod 3 to the support plate 2, first insert the end of the connecting rod 3 into the first slot 6, then rotate the drive column 14 so that the hook piece 16 on the drive column 14 is in a vertical state, and finally lock the hook piece 16 by the buckle 15.

[0052] like Figure 7 and Figure 8As shown, a central shaft 21 is fixedly installed at the center of the rotating disk 12 inside the seat plate 1. The end of the central shaft 21 is rotatably disposed in the disk cavity 13. Thus, the rotation of the rotating disk 12 inside the seat plate 1 can be driven by the central shaft 21, thereby causing the locking pin 10 in the second slot 17 to extend out.

[0053] like Figure 8 A driven wheel 18 is fixedly installed on the central shaft 21. A toothed plate 19 meshes with the outer wall of the driven wheel 18. A spring is fixedly installed between the bottom of the toothed plate 19 and the inner bottom wall of the disk cavity 13. The top of the toothed plate 19 is inserted into the plate groove 20. The plate groove 20 is opened on the seat plate 1. The plate groove 20 is sealed by a plug.

[0054] Therefore, by controlling the up and down movement of the toothed plate 19, the rotation of the driven wheel 18 and the central shaft 21 can be driven, thereby controlling the rotation of the rotating disk 12 inside the base plate 1.

[0055] After the rotating disk 12 is rotated to the appropriate position (the locking pin 10 extends and is locked in the second locking groove 5), the blocking strip seals the plate groove 20 and limits the position of the toothed plate 19.

[0056] The bottom of the toothed plate 19 is supported by a spring (not shown in the figure). When the plug is removed, the toothed plate 19 will automatically move upward under the elastic force of the spring, so that the locking post 10 will also automatically unlock from the second locking groove 5.

[0057] In this invention, the connecting structure only requires a rotating disk 12 or other mechanism to be set inside the seat plate 1 or armrest plate 2. These structures can be integrated into a box, minimizing the impact on the rattan sofa and making it easy to mass-produce. When weaving rattan, it is sufficient to reserve an opening corresponding to the first slot 6 and the second slot 17.
