[0006] To implement the above technical solution, pressure is applied to the U-shaped rod, and the stool surface is changed from a vertical to a horizontal position. The first leg is flipped along the hinge. At the same time, the second leg is flipped until the limit plate collides with the side wall of the second leg. At this time, a stable triangular structure is formed between the first leg, the second leg, the U-shaped rod, and the stool surface. Finally, the four rods are threaded into the four connecting holes respectively, which can increase the height of the stool surface. The operation is convenient, thereby achieving the purpose of improving practicality.

DETAILED DESCRIPTION

[0025] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0026] A quick-detachable folding stool structure includes a stool surface 1, a first leg 11, a second leg 12, a U-shaped rod 13, a first connecting rod 14, and a second connecting rod 15. The stool surface 1 has a circular cross-section. A circular guard plate 10 is fixedly connected to the edge of the stool surface 1 and is coaxial with the stool surface 1.

[0027] The upper end of the first leg 11 is hinged to the stool surface 1 via a pin, and the other end of the first leg 11 extends away from the stool surface 1. The two ends of the U-shaped rod 13 are hinged to the stool surface 1. The two ends of the first connecting rod 14 are respectively fixedly connected to the two first legs 11. The two ends of the second connecting rod 15 are respectively fixedly connected to the two second legs 12.

[0028] The upper end of the second leg 12 is hinged to the side wall of the U-shaped rod 13. The outer wall of the U-shaped rod 13 is fixedly connected to a limit plate 16. The limit plate 16 is used to contact the side wall of the second leg 12. The middle of the first leg 11 and the middle of the second leg 12 are hinged. The two second legs 12 are located between the two first legs 11.

[0029] A connecting hole is provided at one end of the first leg 11 away from the stool surface 1 and at one end of the second leg 12 away from the U-shaped rod 13. The connecting holes are threadedly connected with support rods 2. There are four support rods 2.

[0030] The support rod 2 includes an extension section 21 and a fixed section 22, both of which are cylindrical. A cavity 31 is provided on the extension section 21. The cross-section of the cavity 31 is circular and the cavity 31 is coaxial with the extension section 21. A fixing block 32 is fixedly connected to the outer wall of the fixed section 22, and the two fixing blocks 32 are evenly distributed along the axis of the fixed section 22. A fixing groove 33 with a square cross-section is provided on the inner wall of the cavity 31. A rubber block 34 is fixedly connected to the inner wall of the fixing groove 33, and a trapezoidal groove 35 is provided on the rubber block 34. The fixing block 32 is embedded in the trapezoidal groove 35, and the fixed section 22 is fixed to the cavity 31. The fixed section 22 is used for threaded connection with the connecting hole.

[0031] A sliding hole 4 is formed in the side wall of the extension section 21 and communicates with the cavity 31. A limit post 41 is slidably connected to the sliding hole 4. A support rod 42 is fixedly connected to the inner wall of the extension section 21 and arranged radially along the extension section 21. A spring 43 is fixedly connected between the support rod 42 and the limit post 41. The end of the limit post 41 is hemispherical. The spring 43 is arranged in a V-shape overall.

[0032] A positioning base 5 is fixedly connected to the stool surface 1. The positioning base 5 has four positioning slots 51 defined therein, into which the support rods 2 fit. The four positioning slots 51 are arranged along the length of the positioning base 5. A limiting slot 52 is defined on the inner wall of the positioning slot 51. The limiting slot 52 is U-shaped and has a semicircular cross-section. The end of the limiting post 41 fits into the limiting slot 52.

[0033] The extension section 21 is inserted into the positioning groove 51, the limiting column 41 contacts the inner wall of the positioning groove 51 and is pressed into the sliding hole 4. When the limiting groove 52 corresponds to the limiting column 41, the elastic force of the spring piece 43 causes the end of the limiting column 41 to be embedded in the limiting groove 52, so that the extension section 21 is positioned on the positioning seat 5.

[0034] One end of the extension section 21 away from the fixed section 22 is fixedly connected to a rubber pad 6 .

[0035] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
