[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This utility model combines a base plate, side plates, back plate, right-angle plate, bolts, and fixing bolts. When using the sofa body, the side plates are opened to both sides via hinges and placed horizontally. Then, the right-angle plate is rotated 270° via hinges so that one end of the right-angle plate contacts the ground. The base plate and side plates prevent the bottom of the sofa body from contacting the ground, thus avoiding damage caused by contact between the bottom of the sofa body and sharp objects on the ground. At the same time, the right-angle plate is supported at the back of the sofa body. Then, the bolts are screwed into the ground to fix the right-angle plate, thereby improving the stability of the sofa body during use and further preventing the sofa body from being blown away by the wind when used outdoors.

Then, tighten the fixing bolts to connect them to the threaded side of the side panel, thus securing the side panel to the back plate. Next, loosen the bolts from the ground and the right-angle plate. Then, rotate the right-angle plate using the hinges to overlap the side panel and the front side. After cleaning the bolt surface, screw it into the threaded hole from the front end of the right-angle plate. This allows the deflated sofa to be folded and stored in a sealed box consisting of the base plate, the right-angle plate, and the two side panels, thus preventing wear or damage when carrying the sofa.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0020] Example 1: A portable inflatable sofa, see [link to example]. Figures 1 to 4 The sofa includes a sofa body 1 and a folding and storage mechanism. The sofa body 1 consists of an inflatable seat, an inflatable backrest, and inflatable armrests, which are interconnected. An air nozzle 11 is installed at one end of the sofa body 1, and the air nozzle 11 has a deflation valve. The folding and storage mechanism includes a base plate 2 connected to the middle of the bottom end of the sofa body 1. Both ends of the base plate 2 are hinged to side plates 21. A rear plate 22 is fixedly connected to the rear end of the base plate 2. A right-angle plate 23 is hinged to one side of the top of the rear plate 22. A bolt 31 passes through the right-angle plate 23 and is threadedly connected to the right-angle plate 23. A threaded hole 3 is provided at the front end of the base plate 2, and the threaded hole 3 is adapted to and corresponds to the bolt 31.
[0021] When using the sofa body 1, first, place the base plate 2 on a flat surface. Then, unfold the side panels 21 to both sides via hinges and place them horizontally. Next, rotate the right-angle plate 23 270° via hinges so that one end of the right-angle plate 23 contacts the ground. Then, connect the air nozzle 11 to an external air pump and inflate the sofa body 1. The base plate 2 and side panels 21 prevent the bottom of the sofa body 1 from contacting the ground, thus avoiding damage from sharp objects on the ground. Simultaneously, the right-angle plate 23 supports the backrest of the sofa body 1. Finally, tighten the bolt 31 to insert it into the ground, thus securing the right-angle plate 23 and improving the comfort of the sofa body 1 during use. To ensure stability and further prevent the sofa body 1 from being blown away by the wind when used outdoors, when the sofa body 1 is not in use, the air inside the sofa body 1 is vented through the air release valve on the air nozzle 11. After the vented sofa body 1 is placed on the base plate 2, the side plate 21 is rotated to be perpendicular to the base plate 2 through the hinge. Then, the bolt 31 is loosened to remove it from the ground and the right angle plate 23. The right angle plate 23 is then rotated and overlapped on the top and front of the side plate 21 through the hinge. After cleaning the surface of the bolt 31, it is screwed into the threaded hole 3 from the front end of the right angle plate 23. This allows the vented sofa body 1 to be folded and stored in the sealed box composed of the base plate 2, the right angle plate 23, and the two side plates 21, thus preventing wear or damage to the sofa body 1 when it is carried.
[0022] For details, see Figure 4 The back panel 22 has grooves 6 on both sides of one outer end, and fixing bolts 61 pass through both grooves 6. The fixing bolts 61 are threaded to the surface of the side panel 21. When the side panel 21 is rotated to be perpendicular to the bottom panel 2, the fixing bolts 61 are screwed to make the fixing bolts 61 threaded to the side of the side panel 21, thereby limiting the side panel 21 on the back panel 22, thus preventing the side panel 21 from moving after being folded and affecting the protective effect of the sofa body 1 after deflation.
[0023] Further, see Figure 4 The right-angle plate 23 is inlaid with a first permanent magnet 4 in a rectangular frame, and a second permanent magnet 41 is inlaid at one end of the outer side of the rear plate 22. After the right-angle plate 23 is rotated, the first permanent magnet 4 and the second permanent magnet 41 correspond to each other. The surface magnetic poles of the first permanent magnet 4 and the second permanent magnet 41 are opposite. When the right-angle plate 23 is rotated 270° and one end is supported on the support surface, the first permanent magnet 4 and the second permanent magnet 41 attract each other, thereby improving the stability of the connection between the right-angle plate 23 and the rear plate 22.
[0024] It is worth noting that, see Figure 2 The bolt 31 is connected to a spike 32. The end face size of the spike 32 is the same as that of the bolt 31. The spike 32 makes it easier for personnel to rotate the bolt 31 and insert it into the ground, thus limiting the position of the right angle plate 23.
[0025] It is worth noting that, see Figure 3 A hand-held groove 5 is provided on the right-angle plate 23 in the middle of the first permanent magnet 4. A hand-held rod 51 is fixedly connected between the two sides of the inner cavity of the hand-held groove 5. The hand-held rod 51 makes it easy for people to hold the sofa and carry it after it is folded and stored. The hand-held rod 51 is placed in the hand-held groove 5, so that when the right-angle plate 23 is in contact with the ground, the hand-held rod 51 does not affect the stable contact between the right-angle plate 23 and the ground.
[0026] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
