[0023] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0024] In one embodiment of the present invention, Figures 1 to 5As shown in the figure, a spring mounting structure for a sofa is provided, including a sofa base 1 and a number of serpentine springs 11. On the front and back sides of the sofa base 1, a number of mounting grooves 2 are provided. The two ends of each serpentine spring 11 are respectively fixed in one of the mounting grooves 2. In each mounting groove 2, a buffer plate 21 and a fixing member 3 are provided. The buffer plate 21 is vertically penetrated with an activity groove 22. The fixing member 3 includes a fixing frame 31, a clamping piece 32 and a bolt 33. The bottom of the fixing frame 31 extends downward and slides with a support column 311. The bottom of the support column 311 is fixedly connected to the buffer plate 21. The fixing frame 31 is provided with a sliding groove 312. The clamping piece 32 is slidably connected in the sliding groove 312. A clamping groove is formed between the clamping piece 32 and the support column 311. The bolt 33 is slidably connected in the sliding groove 312. The screw part of the bolt 33 is threadedly connected to the buffer plate 21.

[0025] Further, a number of buffer springs 211 are provided at the bottom of the buffer plate 21. The bottom ends of the buffer springs 211 are fixedly connected to the inner bottom of the mounting groove 2. Specifically, when a user sits on the sofa, the serpentine spring 11 is elastically deformed under extrusion. In existing sofas, the elastic deformation effect is usually achieved only through the serpentine spring 11. Over time, the elastic force in the middle of the serpentine spring 11 weakens, reducing the elastic effect. By providing the buffer springs 211, when the middle of the serpentine spring 11 deforms, the buffer springs 211 are simultaneously elastically compressed under pressure, transferring and balancing the pressure received in the middle of the serpentine spring 11 to both ends, reducing the elastic deformation of the serpentine spring 11, ensuring the elastic effect of the sofa, and prolonging the service life of the serpentine spring 11.

[0026] Further, a guide rod 23 extends upward from the inner bottom of the mounting groove 2. The guide rod 23 passes upward through the buffer plate 21 and is slidably connected to the buffer plate 21. Specifically, during the elastic compression process of the buffer spring 211, by providing the guide rod 23, the up and down movement of the buffer plate 21 can be made more linear, better converting and balancing the elastic deformation of the serpentine spring 11, and further prolonging the service life of the serpentine spring 11.

[0027] Further, a fixing plate 321 is provided at the top of the clamping piece 32. The fixing plate 321 is provided with a screw hole threadedly connected to the bolt 33. Specifically, when the bolt 33 is installed, the U-shaped structure at the end of the serpentine spring 11 surrounds the edge of the activity groove 22, and one side of the U-shaped structure abuts against a support column 311. The top surface of the fixing frame 31 covers the top of the serpentine spring 11. First, the clamping piece 32 is inserted into the sliding groove 312 of the fixing frame 31 and slides towards the serpentine spring 11 until it abuts against the serpentine spring 11. The clamping piece 32 and the support column 311 cooperate to clamp the serpentine spring 11. Then the bolt 33 sequentially passes through the fixing plate 321, the sliding groove 312 and is threadedly connected to the buffer plate 21, better pressing the clamping piece 32 tightly against the side of the serpentine spring 11 to achieve a better clamping effect.

[0028] Further, an arc surface 212 is provided at the top edge of the buffer plate 21, and the arc surface 212 abuts against the serpentine spring 11. Specifically, when the serpentine spring 11 deforms, its middle usually sinks downward. At this time, both ends of the serpentine spring 11 are in close contact with the edge of the buffer plate 21. If the edge of the buffer plate 21 is a relatively sharp angular structure, it is easy to cut the serpentine spring 11, causing damage to the serpentine spring 11. At the same time, the serpentine spring 11 is also likely to damage the edge of the buffer plate 21. Therefore, by providing the arc surface 212 at the edge of the buffer plate 21, the serpentine spring 11 can be better supported by the arc surface 212 when deforming, and the structure of the arc surface 212 is more robust, avoiding damage to the buffer plate 21 by the serpentine spring 11.

[0029] Further, there are at least two sets of the fixing members 3. Specifically, the structure of the serpentine spring 11 is composed of multiple U-shaped structures connected to each other. To ensure a better installation effect, at least two sets of fixing members 3 can be provided to fix both sides of the U-shaped structure of the serpentine spring 11, achieving a better fixing effect. When there are more than three fixing members 3, each side of the U-shaped structure of the serpentine spring 11 can be fixed; the fixing members 3 can be provided within the length range of the movable groove 22 to facilitate maximizing the fixing effect on the end of the serpentine spring 11.

[0030] Further, the screw part of the bolt 33 abuts against the clamping piece 32.

[0031] Working principle: During installation, the sofa base 1 is placed upside down on the workbench, and then both ends of the serpentine spring 11 are respectively fixed in the two opposite installation grooves 2. During installation, by placing the end of the serpentine spring 11 on the buffer plate 21, at this time, the U-shaped structure at the end of the serpentine spring 11 surrounds the edge of the movable groove 22, and one side of the U-shaped structure abuts against a support column 311. The top surface of the fixing frame 31 covers the top of the serpentine spring 11. First, the clamping piece 32 is inserted into the sliding groove 312 of the fixing frame 31 and slides towards the serpentine spring 11 until it abuts against the serpentine spring 11. The clamping piece 32 and the support column 311 cooperate to clamp the serpentine spring 11. Then the bolt 33 passes through the sliding groove 312 and abuts against the clamping piece 32. The screw part at the bottom is threadedly connected to the buffer plate 21, making the clamping piece 32 closely fit with the serpentine spring 11, realizing the position fixation of the serpentine spring 11. The damaged serpentine spring 11 can be disassembled and replaced more precisely. During the maintenance process, the stable installation of other serpentine springs 11 is maintained, avoiding repeated installation of other serpentine springs 11, which is more conducive to the disassembly, installation and maintenance of the serpentine spring 11, reducing the use of wood for the sofa base 1, reducing production costs and reducing the weight of the sofa.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
