[0022] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0023] like Figures 1 to 4 As shown, the foldable conference chair 100 of the present invention has at least an unfolded state (not shown) and a folded state (not shown). The structural center of the foldable conference chair 100 in the folded state coincides with the center of gravity. The foldable conference chair 100 includes a seat 10, a first connecting rod 20, a second connecting rod 30, a connecting member 40, a clamping assembly 50, and two pairs of first chair legs 60 and second chair legs 70 arranged in a cross-pivot arrangement. The two ends of the first connecting rod 20 are respectively mounted on the two first chair legs 60, the two ends of the second connecting rod 30 are respectively mounted on the second chair legs 70, and the seat 10 is detachably arranged above the first connecting rod 20 and the second connecting rod 30. The first end of the connecting member 40 is mounted on the first connecting rod 20, and the second end of the connecting member 40 is pivotally connected to the seat 10. In this embodiment, the clamping assembly 50 is mounted on the second end of the connecting member 40, and the seat 10 is provided with a clamping portion 11 for the clamping assembly 50 to clamp. The first link 20 and the second link 30 jointly support the seat 10 when the foldable conference chair 100 is in the unfolded state. The lifted seat 10 rotates and disengages from the first link 20 and the second link 30, and the rotating seat 10 drives the first leg 60 and the second leg 70 to pivot and fold relative to each other through the connecting member 40, so that the foldable conference chair 100 switches from the unfolded state to the folded state. The clamping assembly 50 is clamped with the clamping portion 11 when the foldable conference chair 100 is in the folded state to achieve locking of the foldable conference chair 100.

[0024] When the foldable conference chair 100 is in the folded state, since the structural center of the foldable conference chair 100 coincides with the center of gravity, the folded foldable conference chair 100 can be placed upright and will not fall over. At the same time, after the snap assembly 50 is snapped with the snap part 11, the foldable conference chair 100 is locked, so that the foldable conference chair 100 is always in the folded state, so that the foldable conference chair 100 can stand stably after being folded, and the foldable conference chair 100 can be stably folded.

[0025] Of course, according to actual needs, the snap assembly 50 can be provided on the seat 10, and correspondingly, the snap portion 11 can be provided on the connecting piece 40, so as to achieve the locking of the foldable conference chair 100. In order to improve the stability and effectiveness of the locking, the foldable conference chair 100 of the present invention is provided with two groups of connecting pieces 40 and two groups of snap assemblies 50, but is not limited thereto.

[0026] like Figures 2 to 6 As shown, the snap-fit ​​assembly 50 includes an elastic member 51 and a snap-fit ​​member 52. The first end of the elastic member 51 is mounted on the connecting member 40, and the snap-fit ​​member 52 is mounted on the second end of the elastic member 51. The elastic member 51 always has a tendency to push the snap-fit ​​member 52 outward, and the snap-fit ​​member 52 is snap-fitted with the snap-fit ​​portion 11 when the foldable conference chair 100 is in a folded state. When the foldable conference chair 100 is in a non-folded state, the snap-fit ​​member 52 is pushed by the elastic member 51 and pressed against the seat 10, and the snap-fit ​​assembly 50 rotates with the rotation of the connecting member 40. Preferably, the snap-fit ​​assembly 50 also includes a mounting member 53. The connecting member 40 is provided with a movable through hole 41, the mounting member 53 is mounted at one end of the movable through hole 41, the elastic member 51 is arranged in the movable through hole 41, the first end of the elastic member 51 is mounted on the mounting member 53, the engaging member 52 is mounted at the second end of the elastic member 51, and the elastic member 51 always has a tendency to push the engaging member 52 out of the movable through hole 41. The engaging assembly 50 is stably mounted to the connecting member 40. For example, the elastic member 51 is a spring, the engaging portion 11 is a slot structure, and the engaging member 52 is a spherical structure, such as a steel ball structure, but is not limited thereto. The mounting member 53 is a pin structure, and the mounting member 53 penetrates into the movable through hole 41 and is mounted to the connecting member 40.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the second end of the connecting member 40 is rotatably mounted on the seat 10 via a pivot shaft 42. The connecting member 40 is arranged in a rod-shaped structure, but is not limited to this. The connecting member 40 includes a first assembly part 43 and a second assembly part 44, the first assembly part 43 is clamped on the first connecting rod 20, the second assembly part 44 is clamped on the first connecting rod 20, and the first assembly part 43 and the second assembly part 44 are fixedly installed. In this way, the connecting member 40 can be simply and stably installed on the first connecting rod 20. The first assembly part 43 and the second assembly part 44 are fixedly installed by screws, but are not limited to this. A strip-shaped through-hole structure 431 is opened in the middle of the first assembly part 43, and the through-hole structure 431 can reduce the weight of the first assembly part 43.

[0028] like Figures 2 to 4As shown, the bottom of the seat 10 is provided with a first slot 12 for engaging the first link 20 and a second slot 13 for engaging the second link 30. The first link 20 is engaged in the first slot 12 when the foldable conference chair 100 is in the unfolded state, and the second link 30 is engaged in the second slot 13 when the foldable conference chair 100 is in the unfolded state. In this way, when the foldable conference chair 100 is in the unfolded state, the seat 10 is engaged in the first link 20 and the second link 30, so that the seat 10 is stably supported by the first link 20 and the second link 30. It can be understood that the first slot 12 and the second slot 13 are arranged at the bottom of the seat 10 in a spaced manner. A mounting seat 14 protrudes from the bottom of the seat 10. The mounting seat 14 is provided with a pivot mounting hole 15 for the pivot shaft 42 to pass through, and the engaging portion 11 is arranged on the end surface of the mounting seat 14 and is located beside the pivot mounting hole 15.

[0029] like Figure 1 and Figure 2 As shown, in the present invention, the bottom ends of the first chair leg 60 and the second chair leg 70 are arranged barefoot. Of course, according to actual needs, pulleys can be installed at the bottom of the first chair leg 60 and the second chair leg 70 to facilitate moving the foldable conference chair 100 to a designated position. Furthermore, a rotatable chair back structure 61 is installed at the top of the first chair leg 60. The chair back structure 61 can support the back of the user, and the chair back structure 61 is rotatable, which is convenient for supporting the back of the user from different angles, making the user comfortable. A handle 71 is installed at the top of the second chair leg 70. The handle 71 can support the wrist of the user and improve the comfort of use. Preferably, the chair seat 10 and the chair back structure 61 of the present invention can adopt existing structures, such as injection molding structure, but not limited to this.

[0030] The following is an introduction to the method of using the foldable conference chair 100 of the present invention: when the conference chair needs to be folded, the seat 10 is lifted up by hand, and the seat 10 rotates upward and is separated from the support of the first connecting rod 20 and the second connecting rod 30. During this process, the rotation of the seat 10 drives the connecting member 40 to flip, thereby linking the first chair leg 60 and the second chair leg 70 to pivot and fold relative to each other, and the first connecting rod 20 and the second connecting rod 30 move closer to each other, so that the foldable conference chair 100 switches from the unfolded state to the folded state, and folding is achieved. When the foldable conference chair 100 switches to the folded state, the elastic member 51 presses the engaging member 52 into the engaging portion 11 to lock the foldable conference chair 100, so that the foldable conference chair 100 is always in the folded state, and the foldable conference chair 100 can stand stably after being folded. The process of opening the foldable conference chair 100 is opposite to the operation process of folding the foldable conference chair 100, so it will not be repeated here.

[0031] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
