Detailed implementation manners
[0033] The following further describes the present application in detail with reference to the Figures 1 - 3 accompanying drawings.
[0034] The embodiment of the present application discloses a folding sofa.
[0035] Referring to Figure 1 , a folding sofa includes a base 1, a seat cushion 2 hinged to the base 1, and an extension cushion 3 hinged to the base 1. A plurality of fixing blocks 10 are fixed on the base 1. Preferably, two fixing blocks 10 are provided, and the two fixing blocks 10 are respectively located on both sides of the base 1. The two fixing blocks 10 are fixed with a fixing rod 11 by screws. Under the action of the fixing blocks 10 and the fixing rod 11, the structure of the base 1 is more stable.
[0036] One side of the seat cushion 2 is hinged to the base 1, and a limiting member 4 is provided on the other side of the seat cushion 2.

When using the folding sofa, the side wall of the limiting block 42 abuts against the base 1, and the seat cushion 2 is stably placed on the base 1. The limiting blocks 42 reduce the wear of the paint surface of the base 1 and play a buffering role.
[0037] The extension cushion 3 includes a front cushion 31 hinged to the base 1 and a rear cushion 32 hinged to the front cushion 31. The rear cushion 32 is hinged to the side of the front cushion 31 away from the seat cushion 2. A support member 6 for supporting the rear cushion 32 away from the ground is provided on the rear cushion 32. Under the action of the rear cushion 32, the front cushion 31 is fixed relative to the ground. A flexible pull ring 9 is fixed between the front cushion 31 and the rear cushion 32, which is convenient for moving the folding sofa.
[0038] Referring to Figure 2 , a storage groove 7 is formed on the side wall of the rear cushion 32, the support member 6 is arranged in the storage groove 7, and a zipper 8 is fixed at the opening of the storage groove 7. Under the action of the pull wire, the opening of the storage groove 7 is closed, preventing the support member 6 from scattering. The support member 6 includes a bracket 61 hinged to the inner wall of the storage groove 7 and a positioning block 62 arranged on the inner wall of the bracket 61. In the embodiment of the present application, the positioning block 62 is preferably a wear-resistant block. When the bracket 61 abuts against the ground, the positioning block 62 abuts against the opening of the storage groove 7, reducing the slip of the bracket 61 and making the relative position of the rear cushion 32 on the ground stable.
[0039] The side walls of the support 61 are fixed with friction blocks 12. The friction blocks 12 are respectively fixed at both ends of the support 61 near the ground side. When unfolding the folding sofa, the support 61 is rotated out from the storage groove 7. Subsequently, the rear cushion 32 drives the support 61 to approach the ground. At this time, the friction blocks 12 are in contact with the ground. The support 61 is kept at a distance from the ground under the action of the friction blocks 12. The setting of the friction blocks 12 replaces the contact between the support 61 and the ground, playing a role in protecting the support 61 and at the same time reducing the possibility of slippage during the use of the folding mattress.

The front cushion 31 and the rear cushion 32 are located above the base 1 under the action of the positioning member 5. The positioning member 5 includes a positioning rod 51 penetrating the side wall of the rear cushion 32 and positioning blocks 52 provided at both ends of the positioning rod 51. The positioning rod 51 is fixed to the inner wall of the rear cushion 32. In the embodiment of the present application, the positioning blocks 52 are preferably made of rubber blocks. The side walls of the positioning blocks 52 abut against the base 1, reducing the wear of the paint surface of the base 1 and playing a buffering role.
[0041] The implementation principle of a folding sofa in an embodiment of the present application is as follows: When unfolding the folding sofa, the support 61 in the storage groove 7 on the side wall of the rear cushion 32 is rotated out, the rear cushion 32 is rotated, the support 61 abuts against the ground, the rear cushion 32 drives the front cushion 31 to rotate, and the side walls of the front cushion 31 and the rear cushion 32 both approach the ground under the action of the support 61. The seat cushion 2 rotates, the limiting block 42 abuts against the base 1, and the side wall of the seat cushion 2 approaches the ground. When folding the folding sofa, the seat cushion 2 rotates, the limiting block 42 moves away from the base 1, the support 61 is stored, and the storage groove 7 is closed by the zipper 8.
