Description

[Technical Field]

[0001] This utility model mainly relates to a sofa structure. [Background Technology] Currently, most sofas on the market use fixed backrest designs or limited position adjustments through simple plug-in methods, which fail to meet users' needs for flexible adjustment of backrest angle and position. Therefore, we propose a sofa backrest connection solution that balances flexibility, adaptability, and structural stability. [Utility Model Content] To solve at least one of the above problems, this utility model proposes a new structural solution. The sofa structure adopts the following technical solution: A sofa structure includes a sofa, a connecting plate, and a backrest. The sofa has a slot for insertion, and the rear end of the slot is an open channel. The connecting plate is an integral structure, comprising a first plate, a second plate, and a third plate. The second plate is horizontally positioned, and the first and third plates are respectively located on both sides of the second plate. The first plate is perpendicular to the second plate, and the third plate is perpendicular to the second plate. The first panel is inserted into the backrest, and the third panel is connected to the insertion slot to assemble the backrest and sofa into a whole through the connecting plate; the second panel extends horizontally from the open channel.

[0002] Preferably, the insertion slot is provided along the length of the sofa, so that the backrest can change its position on the sofa through the connecting plate.

[0003] Preferably, the connection between the first plate and the third plate and the second plate is provided with an arc, so that the connecting plate has elasticity.

[0004] Preferably, the backrest has a slot, with the bottom of the slot open for the insertion of the first plate.

[0005] Preferably, the backrest is provided with a plurality of connecting plates, and the backrest is connected to the insertion slots through each connecting plate.

[0006] The beneficial effects of this utility model compared with the prior art are: This utility model employs an integrated connecting plate design, utilizing the first and third plates tightly fitted into the backrest and the interlocking groove respectively, combined with the horizontally extending structure of the second plate, to achieve flexible adjustment and stable connection of the backrest in multiple positions on the sofa. The connecting plate features an arc at the plate joint, giving it elastic deformation capability, which not only facilitates smooth rotation of the backrest over sofa curves but also enhances the fatigue resistance and lifespan of the connection area. Furthermore, the thickness matching design of the interlocking seam and the interlocking groove ensures tight assembly and smoother backrest movement. The overall structure is simple and reliable, improving the sofa's applicability and comfort. It boasts advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance.

Detailed Implementation Methods

[0007] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0008] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0009] The preferred embodiment provided by this utility model is as follows: Figures 1-3As shown, a sofa structure includes a sofa 1, a connecting plate 2, and a backrest 3. The sofa 1 has a connecting groove 11, the rear end of which is an open channel 12. The connecting groove 11 is arranged along the length of the sofa 1, allowing the backrest 3 to change its position on the sofa 1 via the connecting plate 2. The backrest 3 is equipped with several connecting plates 2, which connect to the connecting groove 11. The connecting plates 2 are divided into several sections that allow the backrest 3 to smoothly rotate over the curves of the sofa 1.

[0010] The connecting plate 2 is an integral structure. The connecting plate 2 includes a first plate 21, a second plate 22 and a third plate 23. The second plate 22 is horizontally arranged. The first plate 21 and the third plate 23 are respectively arranged on both sides of the second plate 22. The first plate 21 is perpendicular to the second plate 22 from the top, and the third plate 23 is perpendicular to the second plate 22 from the bottom. The first plate 21 is inserted into the backrest 3, and the third plate 23 is connected to the insertion slot 11 to assemble the backrest 3 and the sofa 1 into a whole through the connecting plate 2; the second plate 22 extends horizontally from the open channel 12. The connection between the first plate 21 and the third plate 23 and the second plate 22 is curved to make the connecting plate 2 elastic.

[0011] The backrest 3 has a slot 31 inside, with the bottom of the slot 31 open to allow the first plate 21 to be inserted. The thickness of the first plate 21 is slightly greater than the thickness of the slot 31 so that the first plate 21 is tightly fitted into the slot 31. The thickness of the third plate 23 is slightly less than the thickness of the insertion groove 11 so that the third plate 23 can move along the insertion groove 11.

[0012] In the description of this specification, references to terms such as "an embodiment," "preferred," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. Illustrative expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
