[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1, please refer to Figures 1-2 A folding sofa includes several sofa blocks 1, one of which is fixedly connected to a backrest 2; it also includes a folded state and an unfolded state. In the folded state, the sofa blocks 1 are stacked to form a sofa for users to sit on, and in the unfolded state, the sofa blocks 1 are laid flat to form a flat surface for users to play on, providing ample space for family gatherings, children's play and other activities, and meeting diverse usage needs.

[0020] Furthermore, the sofa block 1 connected to the backrest 2 is located at the top layer in the folded state and at the front or rear end in the unfolded state; an armrest 201 is fixedly connected to the backrest 2, and the armrest 201 is also connected to the sofa block 1 connected to the backrest 2. In the folded state, the backrest 2 is used for the user's back to lean against, while the armrest 201 is used for the user's arms to rest.

[0021] Example 2 further optimizes the folding sofa provided in Example 1, specifically, as follows: Figure 2 As shown, the sofa block 1 is fan-shaped, and several sofa blocks 1 form a semi-circle when unfolded. This design allows only two of these products to be spliced ​​together to form a circular movable plane. The fan-shaped structure makes a single product form a regular semi-circle when unfolded, which is not only more visually beautiful and harmonious, but also allows two products to be spliced ​​together to form a complete circle, which can meet the layout needs of different spaces such as living rooms and bedrooms.

[0022] Example 3 further optimizes the folding sofa provided in Example 1. Specifically, the shape of sofa block 1 is a fan shape of one-sixth of a circle, and the number of sofa blocks 1 is three, that is, three sofa blocks 1 can be spliced ​​together to form a semi-circle.

[0023] Example 4 further optimizes the folding sofa provided in Example 1. Specifically, the shape of sofa block 1 is a quarter-circle fan shape, and the number of sofa blocks 1 is two.

[0024] Example 5 further optimizes the folding sofa provided in Examples 1-4, specifically, as follows: Figures 3-7 As shown, a connector is provided between two adjacent sofa blocks 1. The connector includes two connecting grooves 3, which are respectively formed on the two adjacent sofa blocks 1. A connecting shaft 301 is fixedly connected to each of the two connecting grooves 3. A connecting plate 302 is sleeved between the two connecting shafts 301. The connecting grooves 3, connecting shafts 301, and connecting plate 302 cooperate to connect the two adjacent sofa blocks 1 together, allowing the two adjacent sofa blocks 1 to rotate and switch their overall shape. Specifically, when it is necessary to... Figure 3 State switch to Figure 4 In the current state, simply lift the backrest 2 upwards, and then rotate and unfold the several sofa blocks 1 in sequence. When it is necessary to... Figure 4 State switch to Figure 3 In this state, lift the backrest 2 upwards, and then rotate and stack several sofa blocks 1 together in sequence.

[0025] Example 6 further optimizes the folding sofa provided in Example 3, specifically, as follows: Figures 8-11 As shown, each of the three sofa blocks 1 has two threaded holes 402, the middle sofa block 1 has threaded grooves 4 on both sides, the other two sofa blocks 1 have countersunk holes, and two bolts 401 are provided between the three sofa blocks 1.

[0026] Example 7 further optimizes the folding sofa provided in Example 6, specifically, as follows: Figure 8 As shown, in the unfolded state, bolt 401 passes through countersunk hole and is threadedly connected to threaded groove 4. The three flat sofa blocks 1 can be fixed together through the two threaded grooves 4 to maintain stability.

[0027] Example 8 further optimizes the folding sofa provided in Example 6, specifically, as follows: Figure 9 As shown, in the folded state, the bolt 401 is threadedly connected to the threaded hole 402, and the three stacked sofa blocks 1 can be fixed together through the two threaded grooves 4 to maintain stability.

[0028] When it is necessary to Figure 8 State switch to Figure 9 In the current state, unscrew bolt 401, then remove several sofa blocks 1 one by one and assemble them together. Pass bolt 401 through the countersunk hole and thread it into the threaded groove 4. When it is necessary to... Figure 9 State switch to Figure 8In the current state, unscrew bolt 401, then stack several sofa blocks 1 together, and screw bolt 401 into threaded hole 402 to fix the three stacked sofa blocks 1 together.
