[0009] Preferably, the handrail frame has an internal mounting groove, and one end of the pull rod is movably mounted inside the mounting groove.

[0010] Preferably, a handle is installed at the bottom of the pull rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a rotating shaft is used to drive the connecting piece to rotate, connecting the backrest and the seat cushion. A limiting rod then passes through the connecting piece and one of the limiting holes to facilitate positioning, making it easier to fold the backrest and move the conference chair assembly. The support plate has multiple limiting holes. When the connecting piece rotates to the appropriate position, the limiting rod passes through the limiting holes to provide a limiting effect, facilitating the adjustment of the backrest angle.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a lifting and folding integrated conference chair structure, including a conference chair assembly 1, a flipping assembly 2 and an installation and removal assembly 3. The conference chair assembly 1 includes a seat cushion 101, a hydraulic lifting column 102 connected to the bottom of the seat cushion 101, a support frame 103 installed at the bottom of the hydraulic lifting column 102, and casters 104 installed at the bottom of the support frame 103. The flipping assembly 2 includes a backrest 201, a connector 202 connected to the bottom of the backrest 201, a support plate 204 symmetrically installed on one side of the seat cushion 101, a rotating shaft 203 passing through the inside of the support plate 204, the connector 202 being connected to the rotating shaft 203, a plurality of limiting holes 205 being opened on the support plate 204, a limiting rod 206 passing through the inside of one of the limiting holes 205, the limiting rod 206 passing through the inside of the connector 202, a rotating shaft 207 being installed on the side of the backrest 201, and a handle 208 being installed on the rotating shaft 207.

[0023] In this embodiment, the rotating shaft 203 drives the connecting member 202 to rotate, connecting the backrest 201 to the seat cushion 101. A limiting rod 206 then passes through the connecting member 202 and one of the limiting holes 205, facilitating positioning and making it easier to fold the backrest 201. The support plate 204 has multiple limiting holes 205. When the connecting member 202 rotates to a suitable position, the limiting rod 206 passes through the limiting holes 205, providing a limiting effect and facilitating the adjustment of the backrest 201's angle. Furthermore, by controlling the hydraulic lifting column 102 for lifting and lowering, the seat cushion 101 can be lifted and lowered, achieving integrated lifting and folding of the conference chair assembly 1. This improves the flexibility and practicality of the conference chair assembly 1, while also facilitating its folding and movement.

[0024] Example 2: As Figures 1-5 As shown, the mounting and disassembly assembly 3 includes an armrest frame 301, and symmetrically installed insertion slots 302 on the bottom of the seat cushion 101. One end of the armrest frame 301 is slidably installed inside the insertion slot 302. A fixing frame 303 is installed at the bottom of the insertion slot 302. A pull rod 304 passes through the inside of the fixing frame 303. A spring 305 is provided on the outside of the pull rod 304. One end of the spring 305 is connected to the side of the fixing frame 303. An installation slot is opened inside the armrest frame 301. One end of the pull rod 304 is movably installed inside the installation slot. A handle 306 is installed at the bottom of the pull rod 304.

[0025] In this embodiment, when movement is required, the hydraulic lifting column 102 is retracted, thereby lowering the seat cushion 101. Then, the backrest 201 is folded down. By pulling down the handle 306, the pull rod 304 is moved downward, causing the spring 305 to be compressed. This causes the pull rod 304 to release its restraint on the armrest frame 301. The armrest frame 301 is then moved out of the insertion slot 302. The armrest frame 301 is then flipped so that the armrest is facing downward. The armrest frame 301 is then slid back into the insertion slot 302. After moving to the appropriate position, the handle 306 is released. The elasticity of the spring 305 causes the pull rod 304 to restrain the armrest frame 301, which facilitates the handling and movement of the conference chair assembly 1, thereby improving the ease of operation and preventing the loss of parts due to disassembly.

[0026] The working principle of this embodiment is as follows: In use, the rotating shaft 203 first drives the connecting piece 202 to rotate, connecting the backrest 201 to the seat cushion 101. Then, a limiting rod 206 passes through the connecting piece 202 and one of the limiting holes 205, facilitating positioning and making it easier to fold the backrest 201. The support plate 204 has multiple limiting holes 205. When the connecting piece 202 rotates to the appropriate position, the limiting rod 206 passes through the limiting holes 205, providing a limiting effect and facilitating adjustment of the backrest 201's angle. Furthermore, by controlling the hydraulic lifting column 102 for lifting and lowering, the seat cushion 101 can be lifted and lowered, facilitating the lifting and folding of the conference chair assembly 1. The integrated design allows for easy movement of the conference chair assembly 1. When movement is required, the hydraulic lifting column 102 retracts, causing the seat cushion 101 to descend. Subsequently, the backrest 201 is folded down. Pulling down the handle 306 moves the lever 304 downward, compressing the spring 305 and releasing the lever 304 from its restraint on the armrest frame 301. The armrest frame 301 is then moved out of the insertion slot 302, and then flipped over to lower the armrests. The armrest frame 301 is then slid back into the insertion slot 302. After moving to the appropriate position, the handle 306 is released, and the elasticity of the spring 305 allows the lever 304 to restrain the armrest frame 301. This facilitates the handling and movement of the conference chair assembly 1 and prevents the loss of parts due to disassembly.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
