AI Technical Summary
The existing folding chair has a sliding groove design at the connection between the chair legs and the seat cushion that affects the stress performance, and the seat cushion and the chair legs lack linkage, making the operation cumbersome.
The stool uses two first support legs and two second support legs connected by connecting rods. The stool board and the support legs are linked by a linkage to ensure linkage during folding. The unfolding of the support legs is restricted by protruding ribs and connecting ribs to enhance stability.
It achieves the integrity and linkage of the support legs, simplifies operation, and improves the stability and ease of use of the chair.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0018] Example
[0019] like Figs. 1-2 As shown, the folding chair described in this embodiment includes two first support legs 1, two second support legs 2, and a seat board 3. The support legs are preferably made of metal pipes, such as iron pipes. The two first support legs 1 are rotatably connected to the two second support legs 2. The seat board 3 is located on the inner side of the first support legs 1 and the second support legs 2. The two second support legs 2 are fixedly connected to a first connecting rod 21. The fixed connection method includes welding, and also includes bending a whole metal pipe to form the first connecting rod 21 and the two first support legs 1. The two sides of the seat board 3 near the rear end are rotatably connected to the two first support legs 1. The position of the seat board 3 near the front end is rotatably connected to one end of a connecting rod 22, and the other end of the connecting rod 22 is rotatably connected to the first connecting rod 21. When the folding chair is in use, the second support legs 2 support the seat board. In this embodiment, when the chair is folded, the seat board 3 is flipped up, and the second support legs 2 and the first support leg 1 are moved together by the seat board 3. When in use, the connecting rod 22 has a limiting effect on the expansion of the second support legs 2 and the first support leg 1.
[0020] As a preferred embodiment, the two first supporting legs 1 are provided with a second connecting rod 23, the two ends of the second connecting rod 23 are fixedly connected with the two first supporting legs 1 respectively. The fixed connection mode of the second connecting rod 23 can be the same as the connection mode of the first connecting rod 21.
[0021] As a preferred embodiment, the two second supporting legs 2 are provided with a third connecting rod 24, the two ends of the third connecting rod 24 are fixedly connected with the two second supporting legs 2 respectively. The fixed connection mode of the third connecting rod 24 can be the same as the connection mode of the first connecting rod 21.
[0022] As a preferred embodiment, the stool plate 3 comprises a stool surface 31 and a metal supporting frame 32 arranged below the stool surface 31. The stool surface 31 is preferably made of plastic material, and the metal supporting frame 32 enhances the stress performance of the stool surface 31.
[0023] As a preferred embodiment, the metal supporting frame 32 is in a U shape.
[0024] As a preferred embodiment, the outer periphery of the stool surface 31 is provided with a downwardly extending surrounding edge 33, and a rotating shaft 34 is arranged through the first supporting leg 1, the metal supporting frame 32 and the surrounding edge 33 to rotatably connect the stool plate 3 with the first supporting leg 1.
[0025] As a preferred embodiment, a plurality of reinforcing ribs 35 are arranged between the front end of the protruding rib 34 and the surrounding edge 33 and extend in the front-rear direction, and the reinforcing ribs 35 are connected by connecting ribs 36.
[0026] As a preferred embodiment, in the use state, the second supporting leg 2 or the first connecting rod 21 abuts against the stool plate 3. After the second supporting leg 2 or the first connecting rod 21 abuts against the stool plate 3, the expansion movement of the first supporting leg 1 and the second supporting leg 2 is limited, so that the chair is stable and reliable.
[0027] As a preferred embodiment, in the use state, the second supporting leg 2 or the first connecting rod 21 is further expanded by being hindered by the protruding rib 34 or the connecting rib 36. After the second supporting leg 2 or the first connecting rod 21 abuts against the protruding rib 34 or the connecting rib 36, the expansion movement of the first supporting leg 1 and the second supporting leg 2 is limited, so that the chair is stable and reliable.
[0028] In the embodiment, the rear end is close to the hip in the general sitting position, the front end is close to the leg, and the left-right direction is the direction of the user's left and right hands. The use state is the normal expansion state of the seat.
[0029] The above described in the specification is only an example of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace, as long as it does not deviate from the content of the specification of the present application or beyond the scope defined by the claims, it shall belong to the protection scope of the present application.
