[0008] As a preferred solution of the above-mentioned foldable support frame, a buckle is provided on the folding plate.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The utility model provides a foldable support frame, in which a support plate is rotatably mounted on a base and supported by a gas spring, so that the support plate can be positioned and locked at any angle, thereby realizing arbitrary adjustment of the support angle of the support plate; at the same time, the left and right sides of the support plate are respectively rotatably connected with folding plates, and the folding plates can be unfolded or folded according to needs. When in use, the folding plates can be unfolded and flush with the support plates, thereby increasing the supporting area and having a wider range of applications; when not in use, the folding plates can be folded up, do not take up space, and are light and flexible to use.

[0014] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0015] See also Figure 1 and Figure 2 The present embodiment discloses a foldable support frame, including a base 1, the front end of the base 1 is rotatably connected to a support plate 3 through two hinges 2, the top end of the support plate 3 is a free end, the bottom end of the support plate 3 is rotatably connected to the base 1 and can be flipped forward and backward, and the rear side of the support plate 3 is supported by a gas spring 4 installed on the base 1. In this embodiment, the rear side of the support plate 3 is supported by two left and right gas springs 4, and the upper and lower ends of each gas spring 4 are hingedly installed on the support plate 3 and the base 1 respectively. Providing two gas springs 4 can achieve more stable support for the support plate 3.

[0016] The left and right sides of the support plate 3 are rotatably connected with folding plates 5, respectively. The folding plates 5 can be flipped left and right relative to the support plate 3. The support plate 3 is provided with a limit plate 6 for limiting the lower limit position of the flipping of the folding plate 5. When the folding plate 5 flips to contact the limit plate 6, the folding plate 5 is flush with the support plate 3. One end of the folding plate 5 connected to the support plate 3 is a connecting end. The connecting end of the folding plate 5 is provided with two first connecting lugs 7. The end of the support plate 3 is provided with an avoidance groove at the position corresponding to the two first connecting lugs 7 of the folding plate 5. The avoidance groove of the support plate 3 is provided with two second connecting lugs 8. The two first connecting lugs 7 of the folding plate 5 and the two second connecting lugs 8 of the support plate 3 are respectively hinged by rotating joints 9. The rotating joint 9 is a U-shaped frame, and the first connecting lug 7 and the second connecting lug 8 are respectively embedded in the two ends of the U-shaped frame, and the first hinge axis passes through the U-shaped frame and the first connecting lug 7 at the same time, and the second hinge axis passes through the U-shaped frame and the second connecting lug 8 at the same time, so as to realize the hinge connection between the folding plate 5 and the support plate 3.

[0017] A buckle 10 is provided on the folding plate 5 to fix the folding plate 5 in a folded state.
