[0017] Please refer to the attached Figure 1 - attached Figure 3, an embodiment provided by the present utility model: a foldable support frame, including a support plate 1, a plurality of mounting seat components 2 are installed on the lower surface of the support plate 1. The mounting seat component 2 includes a base plate 21, and the base plate 21 is fixedly connected to the lower surface of the support plate 1. Both ends of the base plate 21 are fixedly connected with a first bending plate 24, and the first bending plate 24 is fixedly connected to the lower surface of the support plate 1. A second bending plate 25 is fixedly connected to the first bending plate 24. A guiding surface 27 is provided on the second bending plate 25, and a limiting surface 28 is provided on one side of the guiding surface 27. A support component 3 is hinged on the mounting seat component 2. The support component 3 includes an elastic part 31, a connecting part 32, a support rod 33 and a connecting shaft 34. Both ends of the elastic part 31 are fixedly connected with a connecting part 32. The other end of the connecting part 32 is fixedly connected with a support rod 33. The other end of the support rod 33 is fixedly connected with a connecting shaft 34, and the connecting shaft 34 is hinged on the first bending plate 24. The support plate 1 is an article placement platform and is supported by the support component 3. The base plate 21, the first bending plate 24 and the second bending plate 25 are of an integral structure. The support rod 33 is limited by the gap between the base plate 21, the first bending plate 24 and the second bending plate 25. The elastic part 31, the connecting part 32, the support rod 33 and the connecting shaft 34 are of an integral structure. The elastic part 31 is used to provide a reset elastic force for the support rod 33, and the connecting shaft 34 is used to realize the hinge connection between the support component 3 and the mounting seat component 2; an installation hole 26 is provided on the first bending plate 24, and the connecting shaft 34 is hinged in the installation hole 26. The installation hole 26 is used to install the connecting shaft 34; a through groove 22 is provided on the base plate 21, a limiting plate 23 is fixedly connected in the through groove 22, and the two support rods 33 are respectively arranged on both sides of the limiting plate 23. The limiting plate 23 is used to limit the distance between the support rods 33; an anti-slip sleeve 4 is fixedly connected to the elastic part 31, and the anti-slip sleeve 4 is fixedly connected to the support rod 33. The anti-slip sleeve 4 is used to improve the anti-slip property of the device; a plurality of handles 11 are fixedly connected to the upper surface of the support plate 1. The handles 11 are used to facilitate the transfer of the device and also used to limit the articles placed on the support plate 1; a plurality of through holes 12 are evenly distributed on the support plate 1. The through holes 12 are used to reduce the weight of the support plate 1 and save materials.

[0018] Working principle: When using the present utility model, the support assembly 3 is toggled so that the support assembly 3 deflects to the vertical state on the mounting base assembly 2. During this process, the connecting shaft 34 rotates within the mounting hole 26, and the support rod 33 slides from the limiting surface 28 to the guiding surface 27 and then disengages from the guiding surface 27. Under the elastic action of the elastic part 31, the connecting part 32 drives the support rod 33 to enter the gap between the second bending plate 25 and the substrate 21, where it is blocked and limited. At this time, the support rod 33 is in the vertical state to support the support plate 1. When it is necessary to fold the support assembly 3, a force can be applied to make the two support rods 33 approach each other so that they disengage from the gap between the second bending plate 25 and the substrate 21, and the elastic part 31 bends and deforms. At this time, it can slide along the guiding surface 27 to the limiting surface 28. Under the elastic action of the elastic part 31, the support rod 33 applies pressure on the limiting surface 28 so that it can maintain this folded state. During this process, the limiting plate 23 limits the support rod 33 to prevent the connecting shaft 34 from disengaging from the mounting hole 26 when the support rod 33 is in the vertical state, thereby improving safety. Among them, the handle 11 is used to facilitate the transfer of the device and also to limit the items placed on the support plate 1. The through hole 12 is used to reduce the weight of the support plate 1 and save materials. The through groove 22 is used to accommodate the limiting plate 23. The anti-slip sleeve 4 is used to increase the frictional resistance to prevent the device from sliding. The substrate 21, the limiting plate 23, the first bending plate 24, and the second bending plate 25 are of an integral structure. The elastic part 31, the connecting part 32, the support rod 33, and the connecting shaft 34 are of an integral structure.
