[0020] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features, and effects of the present utility model as follows.

[0021] Embodiment 1:

[0022] A folding frame provided in this embodiment, as Figure 1 , Figure 4As shown in the figure, it includes a flexible working surface 1, a working surface support 2 and a support leg frame 3. The support leg frame 3 includes a first mounting seat 4 and at least three legs 5. The legs 5 are hinged to the first mounting seat 4. The working surface support 2 includes a second mounting seat 6 and at least three support legs 7. One end of the support leg 7 is hinged to the second mounting seat 6, and the other end of the support leg 7 is detachably connected to the flexible working surface 1. The first mounting seat 4 is connected to the second mounting seat 6; in the state where the support leg 7 and the legs 5 are folded in place, the free ends of the support leg 7 and the legs 5 face the same direction; in the state where the flexible working surface 1 is fully unfolded, the angle between the support leg 7 and the second mounting seat 6 is less than 180°, and the opening direction of the angle between the support leg 7 and the second mounting seat 6 is opposite to the opening direction of the angle between the legs 5 and the first mounting seat 4; it also includes a limiting structure, and the limiting structure is used to block the support leg 7 from folding inward in the state where the flexible working surface 1 is fully unfolded. In this embodiment, four support legs 7 are provided and four legs 5 are provided. The folding frame can be used as a table or a chair. The flexible working surface 1 is made of PVC mesh fabric, and the first mounting seat 4 and the second mounting seat 6 are made of nylon material.

[0023] The flexible working surface 1 is designed to be detachable, which is convenient to remove the flexible working surface 1 during folding, facilitating the folding of the working surface support 2 and the support leg frame 3. It can also keep the flexible working surface 1 away from the ground, reducing pollution and making it easier to clean the flexible working surface 1; compared with the support leg 7 folding inward at the upper part and the legs 5 folding inward at the lower part, the outer ends of the support leg 7 and the legs 5 face the same direction after folding, that is, both the support leg 7 and the legs 5 fold inward at the upper part or both fold inward at the lower part, shortening the overall length after folding and being more conducive to storage and carrying; in the unfolded state, the outward opening of the support leg 7 is restricted by the flexible working surface 1, and the inward folding of the support leg 7 is restricted by the limiting structure, ensuring the reliable opening of the support leg 7 and thus ensuring the reliable use of the flexible working surface 1; when folding is needed, only by disassembling the flexible working surface 1 can the restriction on the movement of one side of the support leg 7 be released.

[0024] To ensure the reliable connection between the first mounting seat 4 and the second mounting seat 6, the first mounting seat 4 and the second mounting seat 6 are connected through a guide member 8. One end of the guide member 8 is connected to the first mounting seat 4, and the other end of the guide member 8 is slidably connected to the second mounting seat 6. The second mounting seat 6 is located below the first mounting seat 4. The support leg 7 and the legs 5 are cross-hinged, enabling the support leg 7 and the legs 5 to form a linkage, making the unfolding and folding more convenient. At the same time, the rotation of the support leg 7 will drive the second mounting seat 6 to slide along the guide member 8.

[0025] In this embodiment, the guide member 8 is a square tube, and square holes adapted to the square tube are formed on both the first mounting seat 4 and the second mounting seat 6, so that the first mounting seat 4 and the second mounting seat 6 cannot rotate relative to each other. Of course, the guide member 8 can also be a round tube or a tube of other shapes, as long as holes of a matching shape are formed on the first mounting seat 4 and the second mounting seat 6, the guiding function can be achieved.

[0026] To make the installation of the support leg 7 more reliable, as Figure 3 shown, the second mounting seat 6 is provided with an outwardly extending mounting plate 9, and the support leg 7 is hinged to the mounting plate 9; a first limiting surface 10 is provided beside the mounting plate 9, and in the state where the support leg 5 is folded in place, the support leg 5 is in contact with the first limiting surface 10. In this embodiment, the mounting plates 9 are arranged on both sides of the support leg 7 to provide better support for the support leg 7. The design of the mounting plate 9 facilitates the installation of the support leg 7; the first limiting surface 10 is used for limiting when the support leg 5 is folded in place.

[0027] To facilitate the installation of the flexible working surface 1, as Figure 5 shown, the edge of the flexible working surface 1 is provided with a mounting sleeve 11, and in the state where the flexible working surface 1 is fully unfolded, one end of the support leg 7 is located inside the mounting sleeve 11. The design of the mounting sleeve 11 makes the disassembly and assembly of the support leg 7 and the flexible working surface 1 simple and convenient.

[0028] For convenient storage, the top surface of the first mounting seat 4 is a flat surface, which can be placed in contact with a wall surface or the like; a groove 12 is provided on the first mounting seat 4, and the groove 12 can facilitate the grasping of the first mounting seat 4.

[0029] To reduce the folding volume, the support leg 5 is telescopic; the support leg 5 includes a first support rod 13 and a second support rod 14. One end of the first support rod 13 is connected to the first mounting seat 4, and the other end of the first support rod 13 is slidably sleeved on the second support rod 14; the first support rod 13 and the second support rod 14 are limited by a ball structure, and the ball structure for fixing is a prior art, such as the unfolding and fixing of the umbrella rod in a folding umbrella, which will not be elaborated herein. In this embodiment, both the first support rod 13 and the second support rod 14 are tubes.

[0030] To make the support more stable, a support foot pad 15 is provided at the bottom of the second support rod 14; an outwardly extending support flat plate 16 is provided on the support foot pad 15, and in the state where the support leg 5 is unfolded in place, the support flat plate 16 is in contact with the ground. In this embodiment, the support foot pad 15 is made of PU material, which is soft and wear-resistant, can cope with different environments, and can be used in scenarios such as grasslands, beaches, and forests. The design of the support flat plate 16 increases the contact area with the ground, making the placement of the folding rack more stable.

[0031] In order to reduce the folding volume, the supporting leg 7 is telescopic; the supporting leg 7 includes a first support rod 17 and a second support rod 18. One end of the first support rod 17 is connected to the second mounting seat 6, and the other end of the first support rod 17 is slidably sleeved on the second support rod 18; the first support rod 17 and the second support rod 18 are limited in position by a ball structure. The ball structure for fixing is prior art, such as the unfolding and fixing of the umbrella rod in a folding umbrella, which will not be elaborated herein. Both the first support rod 17 and the second support rod 18 are pipe materials.

[0032] For the reliable limiting structure, such as Figure 2 As shown, the limiting structure includes a second limiting member 19. In the state where the supporting leg 7 is fully extended, the second mounting seat 6 or the supporting leg 7 is in contact with the second limiting member 19. In this embodiment, the second limiting member 19 is located below the guiding member 8, and the second limiting member 19 extends beyond the circumference of the guiding member 8. In the state where the supporting leg 7 is fully extended, the second mounting seat 6 contacts the second limiting member 19, and the second limiting member 19 blocks the second mounting seat 6 from moving downward continuously. Of course, the second limiting member 19 can also be located on the mounting plate 9 to block the supporting leg 7 from rotating upward continuously.
