[0002] A triangular stool is a stool with a unique structure. According to its name, it can be interpreted as a stool with a triangular support structure. It is a folding stool different from a tripod stool. A tripod stool generally refers to a stool with three fixed supporting legs (such as the triangular tripod stool disclosed in announcement number CN2624725Y). A triangular stool generally has a folding function.

[0003] Common triangular stools are usually composed of three legs and a stool surface, thereby forming a stable triangular structure for users to squat and sit (such as the folding triangular stool disclosed in publication number CN104622070A). When folded, it usually shrinks in a cylindrical shape, which can shrink the volume to a large extent, but it will also increase its storage length (the larger the stool surface, the larger the storage length after shrinkage). At the same time, its defects in daily use are also obvious. In addition to the above-mentioned storage length, it is also easy to unfold twice when stored and carried, unless it is tied with a cable tie or held at the end of the triangular stool after storage, but it also has certain requirements on the size of the user's palm.

[0026] In this embodiment, the folding frame 1 includes a rotating shaft 3 and a supporting frame 4; wherein the rotating shaft 3 is vertically arranged, and its upper and lower ends are fixedly connected with hinges 5, the number of the supporting frames 4 is two groups, and they are symmetrically arranged about the rotating shaft 3, the supporting frame 4 is composed of a horizontally arranged upper crossbeam 6 and a lower crossbeam 7 and a vertically arranged supporting rod 8, the upper crossbeam 6 and the lower crossbeam 7 are arranged in parallel up and down, one end of the two is hingedly connected to the upper and lower ends of the rotating shaft 3 through the hinge 5, and the other end of the two is hingedly connected to the upper and lower ends of the supporting rod 8, at this time, the supporting frame 4 is symmetrical about the rotating shaft 3, and the hinge can be folded and unfolded;

[0027] In addition, in order to limit its unfolded state to achieve the effect of triangular support, in this embodiment, a folding link 9 is arranged between the support rods 8 on the two support frames 4. The number of the folding links 9 is two groups, and they are symmetrically arranged up and down, and are used for connecting and interacting the far ends of the two support frames 4; specifically, the folding link 9 is composed of a hinge plate 10 and two links 11, and one end of the two links 11 is hingedly connected through the hinge plate 10, so that the links 11 can be folded and unfolded with respect to the hinge plate 10; in the two groups of folding links 9, the ends of the links 11 at both ends of the folding links 9 located above are hingedly connected to the upper ends of the support rods 8 on the two support frames 4, and the ends of the links 11 located .... The ends of the connecting rods 11 at both ends of the folding connecting rod 9 below are hingedly connected to the lower ends of the support rods 8 on the two support frames 4; at this time, when the folding connecting rod 9 is unfolded, the folding frame 1 will be in a triangular support state and can be used as a triangular stool, and when the folding connecting rod 9 is folded and retracted, the support frames 4 are closed together, and the triangular stool is in a retracted state. When carrying it, you only need to hold the rotating shaft 3 with one hand to carry it easily. At this time, the length of the triangular stool after storage will not increase significantly, and, when holding the rotating shaft 3 for carrying, the triangular stool after storage will not be easily unfolded again, but under the action of gravity, the two support frames 4 naturally approach and close.

[0028] Example 2

[0029] Based on a portable horizontally foldable triangular stool disclosed in Example 1, tenons 12 are provided at the upper and lower ends of the rotating shaft 3, and a tenon groove 13 is provided in the middle of the hinge 5. The tenons 12 and the tenon groove 13 are matched with each other, and the hinge 5 is fixedly installed at the upper and lower ends of the rotating shaft 3 by mortise and tenon connection, so that the rotating shaft 3 and the hinge 5 have a relatively stable connection structure and reduce the difficulty of assembly and installation;

[0030] At the same time, one end of the connecting rod 11 hinged with the hinge plate 10 is provided with a hinge groove 14, and a first hinge hole 15 is opened, and both ends of the hinge plate 10 are provided with symmetrical second hinge holes 16, the first hinge hole 15 and the second hinge hole 16 are matched, and an axle pin 17 is inserted to realize the hinge connection between the connecting rod 11 and the hinge plate 10;

[0031] In addition, it is not difficult to see that, based on the content of Example 1, the folding direction of the folding link 9 can be toward the inside of the folding frame 1 or toward the outside of the folding frame 1. When it is folded toward the outside of the folding frame 1, it will undoubtedly increase the length of the triangle stool in the folded state. For this reason, in this embodiment, the two corners adjacent to the second hinge hole 16 on the hinge plate 10 are respectively an arc-shaped fillet 18 and a 90° right angle 19. The arc-shaped fillet 18 and the 90° right angle 19 are symmetrically arranged on the hinge plate 10, and the 90° right angle 19 is at the hinge. The plate 10 is located on the side facing the rotating shaft 3, while the arc-shaped fillet 18 is located on the side facing away from the rotating shaft 3 on the hinge plate 10; when the tripod is in use (the folding connecting rod 9 is unfolded), at this time, the 90° right angle 19 abuts against the inner bottom surface of the hinge groove 14, and limits the connecting rod 11 from continuing to bend toward the outside of the folding frame 1, and when the tripod is folded, the connecting rod 11 can only bend toward the inside of the folding frame 1, so that the folding connecting rod 9 is stored in the supporting frame 4, effectively ensuring that the tripod occupies very little space in the stored state for easy storage.
