[0032] Example 1

[0033] like Figure 1-7 As shown, this embodiment provides a sofa that is easy to assemble and disassemble, including a support frame 1, a backrest frame 5 snapped onto one side of the support frame 1, a support frame 4 fixedly connected inside the support frame 1, a seat cushion 2 on the top of the support frame 4, and a backrest cover 3 fitted onto the backrest frame 5, with the seat cushion 2 abutting against the backrest cover 3. By setting the support frame 4, during use, the support frame 4 and the support frame 1 cooperate to provide load-bearing force. Due to the special structural design of the support frame 4, the support frame 4 can increase the elasticity of the sofa, thereby improving the comfort of the sofa. By setting the backrest frame 5, during use, the structure of the backrest frame 5 can better conform to the human body structure, providing lumbar support for the user, thereby increasing the comfort of the sofa. At the same time, the backrest frame 5 and the support frame 4 cooperate to increase the cushioning effect, further improving the comfort of the sofa.

[0034] The support frame 1 is a square frame structure. Compared with traditional box-type modular sofas, choosing the support frame 1 as the support body can greatly reduce the weight of the sofa, making it easier to move and reducing costs, making it suitable for rental housing. The inner side wall of the support frame 1 has a first mating groove 6. There is a pair of first mating grooves 6, which are respectively distributed on opposite side walls along the length of the support frame 1. A second mating groove 7 is provided below the first mating groove 6. A third mating groove 8 is provided on one side of the top of the support frame 1. A fourth mating groove 9 is provided on one side of the third mating groove 8. The fourth mating groove 9 is connected to the corresponding second mating groove 7. A support foot 10 is provided at the bottom corner of the support frame 1. The support foot 10 is fixedly connected to the support frame 1. The edges and corners of the support frame 1 are provided with rounded chamfers. By setting the chamfers, the aesthetics can be increased, and the safety can also be increased to avoid injury to users from sharp parts.

[0035] The support frame 4 is a wave-shaped elastic plate. The side of the support frame 4 is adapted to the first mating groove 6. When the support frame 4 and the first mating groove 6 are installed inside the support frame 1, the highest point of the support frame 4 does not exceed the top horizontal plane of the support frame 1, while there is a large space between the lowest point of the support frame 4 and the bottom horizontal plane of the support frame 1. This space can be used to place the disassembled backrest frame 5 and backrest cover 3, which not only avoids the loss of parts after the sofa is disassembled, but also increases the storage function of the support frame 1 and facilitates the transportation of the sofa. When the seat cushion 2 is placed on the support frame 1, its edge is embedded in the inside of the support frame 1 and is interference-fitted with the support frame 1, thereby preventing the seat cushion 2 from sliding relative to the support frame 1 and increasing the comfort of the support frame 1. Due to the large thickness of the seat cushion 2, when the seat cushion 2 contacts the support frame 4, the top of the seat cushion 2 still exceeds the top horizontal plane of the support frame 1 by 3-5cm. The use of the seat cushion 2 and the support frame 4 together can further increase the softness and elasticity of the sofa, thereby ensuring that the user has a good user experience.

[0036] The support frame 4 is provided with reinforcing wings 12 on both sides. One end of the reinforcing wing 12 is fixedly connected to the support frame 4, and the other end of the reinforcing wing 12 is adapted to the second mating groove 7. The included angle between the reinforcing wing 12 and the support frame 4 is less than 90°. When the support frame 4 is installed inside the bearing frame 1, the reinforcing wing 12 engages with the bearing frame 1 in conjunction with the second mating groove 7. The support frame 4, the reinforcing wing 12 and the bearing frame 1 form a triangular structure. The reinforcing wing 12 can distribute the force on the support frame 4, thereby increasing the stability of the support frame 4, reducing the risk of deformation or even breakage of the support frame 4, and extending the service life of the support frame 4. The surface of the support frame 4 is provided with multiple sets of first lightweight grooves 11. By setting multiple sets of first lightweight grooves 11, not only can the weight of the support frame 4 be reduced, thus facilitating the movement of the sofa, but it can also save materials and reduce production costs. Furthermore, the first lightweight grooves 11, when used in conjunction with the seat cushion 2, can increase the breathability of the sofa and optimize the user experience.

[0037] The backrest frame 5 is an irregularly curved plate that conforms to the structure of the human back. During use, it can provide lumbar support for the user, thereby increasing comfort and further optimizing the user experience. The bottom of the backrest frame 5 is fixedly connected to a mating plate 14, and a riveting plate 15 is fixedly connected to one side of the mating plate 14. The riveting plate 15, the mating plate 14, and the backrest frame 5 form a Y-shaped structure. The structure of the mating plate 14 is adapted to the fourth mating groove 9, and the structure of the riveting plate 15 is adapted to the third mating groove 8. The mating plate 14 and the backrest frame 5 have the same thickness, the riveting plate 15 is thicker than the mating plate 14, and the mating plate 14 is thinner than the width of the fourth mating groove 9.

[0038] During actual installation, the mating plate 14 is embedded in the fourth mating groove 9, and there is a certain gap between it and the side wall of the fourth mating groove 9. This allows the mating plate 14 to move inside the fourth mating groove 9. The riveting plate 15 is embedded in the third mating groove 8 and is in close contact with the inner wall of the third mating groove 8. When the backrest frame 5 is subjected to pressure from the user, it will deform to a certain extent, thereby buffering the impact force when the human body leans against it, and driving the mating plate 14 to move closer to the reinforcing wing 12 inside the fourth mating groove 9. The reinforcing wing 12 abuts against the mating plate 14 and limits the mating plate 14, thereby preventing the backrest from being blocked. The backrest frame 5 is tilted excessively to ensure a cushioning effect for the user. Multiple sets of second lightweight grooves 13 are provided on the side wall of the backrest frame 5. The corners of the inner wall of the second lightweight grooves 13 are provided with arc-shaped chamfers. By providing second lightweight grooves 13 on the backrest frame 5, the weight of the backrest frame 5 can be reduced, making it easier to move the sofa. It can also save materials and reduce production costs. In addition, when used with the backrest cover 3, it can increase the breathability of the backrest and optimize the user experience. Multiple sets of reinforcing ribs 16 are provided on the backrest frame 5 to enhance the structural strength of the backrest frame 5 and extend the service life of the backrest frame 5.

[0039] Work steps

[0040] Step 1: When installing the support frame 4, first press the end of the reinforcing wing 12 to retract the end of the reinforcing wing 12 until it can be aligned with the corresponding second mating groove 7 port. Then release the reinforcing wing 12 so that the reinforcing wing 12 enters the second mating groove 7 and engages with the support frame 1. Then, insert the two sides of the support frame 4 into the corresponding first mating groove 6 and engage with the support frame 1.

[0041] Step 2: When installing the backrest frame 5, first embed the mating plate 14 into the fourth mating groove 9, and then embed the rivet plate 15 into the third mating groove 8. After the backrest frame 5 is installed, it will be sleeved on the outside of the backrest frame 5. Finally, place the seat cushion 2 on the top of the support frame 1 and press the seat cushion 2 to embed it into the support frame 1.

[0042] Step 3: When it is necessary to move the sofa and thus disassemble it, first remove the backrest cover 3 from the backrest frame 5, then lift the backrest frame 5 to separate it from the support frame 1, turn the support frame 1 upside down, place the backrest frame 5 inside the support frame 1, and at the same time place the disassembled backrest cover 3 inside the support frame 1.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
