DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

(11) Referring to FIGS. 1 to 9, a folding stool comprises two boards 10 and a folding frame 20. The folding frame 20 comprises a left frame 22 and a right frame 24. The left frame 22 and the right frame 24 are respectively disposed on a periphery of a bottom surface of a corresponding one of the two boards 10. Inner sides of front ends of the left frame 22 and the right frame 24 are provided with front hinge pieces 26 that are hinged to each other. That is, the left frame 22 and the right frame 24 are respectively provided with a front hinge piece 26, and the two front hinge pieces 26 are hinged together. Inner sides of rear ends of the left frame 22 and the right frame 24 are provided with rear hinge pieces 28 that are hinged to each other. That is, the left frame 22 and the right frame 24 are respectively provided with a rear hinge piece 28, and the two rear hinge pieces 28 are hinged together. In this way, the left frame 22 and the right frame 24 can be folded or unfolded relative to each other. In the present embodiment, the inner side refers to a side where the left frame 22 and the right frame 24 are close to each other (i.e., the inner side of the left frame 22 faces the right frame 24 and the inner side of the right frame 24 faces the left frame 22), and an outer side refers to a side where the left frame 22 and the right frame are away from each other (i.e., the outer side of the left frame 22 faces away from the right frame 24 and the outer side of the right frame 24 faces away from the left frame 22). The left frame 22 and the right frame 24 are also provided with support legs disposed below the outer sides of the left frame 22 and the right frame 24. The support legs are conventional and will not be described.

(12) The folding frame 20 further comprises two middle support legs 21 symmetrically disposed. Tops of the two middle support legs 21 are hinged with the front hinge pieces 26 and the rear hinge pieces 28 respectively. The middle support legs 21 are each provided with a sliding sleeve 212. That is, both middle support legs 21 are provided with a sliding sleeve 212. Each of the sliding sleeves 212 is respectively connected to the left frame 22 and the right frame 24 by a link rod 214. That is, each of the sliding sleeves 212 is connected to two link rods 214, and the two link rods 214 are respectively disposed corresponding to the left frame 22 and the right frame 24. Connection points at two ends of each of the link rods 214 are rotating hinge points. That is, one end of each of the link rods 214 is hinged with the sliding sleeve 212, and the other end of each of the link rods 214 is hinged with the left frame 22 or the right frame 24.

(13) When folded, the left frame 22 and the right frame 24 are centered on rotation points of the front hinge pieces 26 and the rear hinge pieces 28 and are concurrently brought close to the two middle support legs 21 until they are stacked together. Each of the sliding sleeves 212 slides from an upper part of a corresponding one of the two middle support legs 21 to a lower part of the corresponding one of the two middle support legs 21.

(14) In some embodiments, the rotation points of the two middle support legs 21, rotation points of the two front hinge pieces 26, and rotation points of the two rear hinge pieces 28 are collinear.

(15) In some embodiments, the two middle support legs 21 are respectively disposed on inner sides of the front hinge piece 26 and the rear hinge piece 28. That is, in a direction facing toward a center of the folding frame 20. Each of the link rods 214 is hinged to the inner side of the left frame 22 or the right frame 24.

(16) In some embodiments, a fixing rod 50 is connected between the two middle support legs 21 so that the two middle support legs 21 can form an integral unit.

(17) The left frame 22 and the right frame 24 are rectangular frames. The left frame 22 is provided with a crisscross reinforcing frame 221, and the right frame 24 is provided with a crisscross reinforcing frame 241. The crisscross reinforcing frames 221, 241 improve a carrying capacity of the two boards 10.

(18) In some embodiments, a lock and an elastic member are provided at a position of the front hinge pieces 26 or the rear hinge pieces 28. One end of the lock is hinged to one of the front hinge pieces 26 or one of the rear hinge pieces 28, and another end of the lock is driven by the elastic member to abut another one of the front hinge pieces or another one of the rear hinge pieces to prevent the front hinge pieces 26 and the rear hinge pieces 28 from accidentally rotating.

(19) Each of the boards 10 comprises an upper plastic blister board 11 and a lower plastic blister board 12 bonded together. A top surface of the lower plastic blister board 12 is provided with a protruding platform to support the upper plastic blister board 11.

(20) It can be understood that the structure of this embodiment can be applied to a folding table. That is, the folding table has the same structure as that of the folding stool of this embodiment.

(21) It will be apparent to those skilled in the art that various modifications and variation can be made in the present disclosure without departing from the spirit or scope of the disclosure. Thus, it is intended that the present disclosure cover the modifications and variations of this disclosure provided they come within the scope of the appended claims and their equivalents.
