[0002] Chairs are essential furniture for daily home and office use. Currently, common chairs include wooden chairs and plastic chairs. Nowadays, chairs are increasingly focused on ergonomics, but wooden chairs are more difficult to achieve this function. Therefore, ergonomic chairs are more often made of plastic. For the sake of beauty and lightness, the thickness of plastic chairs has also begun to decrease, but this has also affected the difficulty and strength of the bracket installation. On the one hand, the bracket is prone to cracking at the installation position during installation, and on the other hand, the bracket is prone to deformation during installation, resulting in white marks on the seat due to deformation.

[0003] Therefore, the installation between the plastic seat and the bracket also needs to be improved. Utility Model Content

[0008] As a further improvement of the present invention, the reinforcing ribs of the first connecting structure and the second connecting structure corresponding to the center position of the seat are spaced apart at larger intervals or have shorter lengths.

[0009] As a further improvement of the present invention, the connecting piece also includes a cover body, which is provided with a connecting groove at a position corresponding to the reinforcing rib, the connecting groove cooperates with the reinforcing rib for the reinforcing rib to be embedded, and the cover body covers the first connecting structure or the second connecting structure.

[0010] As a further improvement of the present invention, the cover body is provided with a protrusion at a gap between two adjacent reinforcing ribs, and when the cover body is connected to the reinforcing ribs, the protrusion is inserted into the gap.

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0024] Reference Figure 1-8 As shown,

[0025] A seat and a seat node connection structure, including a connection member 2 arranged on a seat 1, the connection member 2 is connected in conjunction with a bracket; the connection member 2 includes a first connection structure 21 corresponding to a hip position and a second connection structure 22 corresponding to a leg position, the first connection structure 21 and the second connection structure 22 both include a connection column 3 for cooperating with a bolt connection and a plurality of reinforcing ribs 4 connected to the connection column 3, the reinforcing ribs 4 are distributed circumferentially along the connection column 3 and connected to the bottom surface of the seat 1, and the reinforcing ribs 4 of the first connection structure 21 are connected to each other corresponding to the other end of the connection column 3.

[0026] A threaded hole can be set on the connecting column 3 to cooperate with the bracket and bolts for connection. The cooperation of the reinforcing rib 4 can improve the radial strength of the connecting column 3. On the one hand, it can maintain a relatively stable thread fit between the connecting column 3 and the bolt, and on the other hand, it can alleviate the expansion and cracking of the connecting column 3. In addition, the reinforcing rib 4 can also make the connecting column 3 difficult to tilt, so that the connecting column 3 and the seat maintain a relatively fixed position, which can also alleviate the problem of white marks caused by deformation of the plastic material. The first connecting structure 21 and the second connecting structure 22 correspond to the hip position and the leg position respectively, so that the support is more comprehensive. At this time, the position in the middle of the seat has a better deformation effect, which can make the user sit more comfortably. At the same time, it also maintains the strength of the connection, making it difficult to deform and alleviating the white mark problem.

[0027] Reference Figure 1 , 2 As shown in , 3, the number of the first connection structure 21 and the number of the second connection structure 22 are both two.

[0028] In a further configuration, the first connection structure 21 further includes a connection enclosure 5 , and the other ends of the reinforcing ribs 4 of the first connection structure 21 corresponding to the connection columns 3 are connected to the enclosure 5 ; the enclosure 5 at least surrounds a portion of the reinforcing ribs 4 .

[0029] Firstly, the enclosure 5 can strengthen the seat 1 , and at the same time connect a plurality of reinforcing ribs 4 together, which can make the strength of these reinforcing ribs 4 higher.

[0030] In a preferred solution, the enclosure 5 is arc-shaped, and the adjacent reinforcing ribs 4 and the enclosure 5 surround and form a groove 6 .

[0031] The arc-shaped enclosure 5 can be adapted to the circumferential arrangement of the reinforcing ribs 4, and the formed groove 6 has a good reinforcing effect while also having the effects of saving materials and being lightweight.

[0032] In fact, the enclosure 5, the reinforcement ribs 4, and the seat 1 can all be integrally formed and made of plastic material, so the structure has better strength based on being made of plastic material.

[0033] In a further optimized example, the first connection structure 21 and the second connection structure 22 are spaced apart from each other at the center of the seat 1 or the length of the reinforcement ribs 4 is shorter.

[0034] Since the center of the seat 1 is subjected to greater force, it is prone to deformation. The distribution of the reinforcing ribs 4 based on this solution can avoid the situation where the spacing between the reinforcing ribs 4 corresponding to the center of the seat 1 is too small or the strength is too high, resulting in white marks when the center of the seat 1 is deformed, and the deformation can have a transitional effect.

[0035] Reference Figure 5 , 6 As shown in , the reinforcing ribs 4 corresponding to the buttocks are distributed at larger intervals, while the reinforcing ribs 4 corresponding to the legs are shorter.

[0036] In addition, in order to increase the aesthetics, the connector 2 also includes a cover body 7, which is provided with a connecting groove 71 at the position corresponding to the reinforcing rib 4. The connecting groove 71 cooperates with the reinforcing rib 4 for the reinforcing rib 4 to be embedded, and the cover body 7 covers the first connecting structure 21 or the second connecting structure 22.

[0037] The cover body 7 can cover the reinforcing ribs 4 to achieve a better aesthetic effect, while also reducing problems such as dust accumulation and facilitating cleaning.

[0038] In addition, the cover body 7 can provide a buffering effect while having a certain strength. Figure 7 , 8 As shown in , it is trumpet-shaped. The connection groove 71 of the cover body 7 can be a through-hole structure or a blind hole structure, which can allow the reinforcing rib 4 to be embedded and connected. Based on this connection, the cover body 7 can be circumferentially fixed and have better stability.

[0039] In addition, as an example of optimizing the cover body 7, a protrusion 72 is provided on the cover body 7 at a gap between two adjacent reinforcing ribs 4, and when the cover body 7 is connected to the reinforcing rib 4, the protrusion 72 is inserted into the gap.

[0040] The position of the protrusion 72 is matched with the interval between the reinforcing ribs 4. When the size is appropriate, the protrusion 72 can abut against the adjacent reinforcing ribs 4. When the strength of the cover body 7 is appropriate, the strength of the reinforcing ribs 4 can be strengthened, so that the reinforcing ribs 4 can be supported laterally. Of course, it can also play a more positioning role, so that the cover body 7 and the reinforcing ribs 4 are convenient to install.

[0041] In addition, in an optional example, the other end of the reinforcing rib 4 corresponding to the connecting column 3 is inclinedly transitioned from one side of the bracket to the surface of the bottom of the seat 1.

[0042] Reference Figure 5 , 6 As shown in , the inclined transition can make it more adaptable to the trumpet-shaped cover 7, with better aesthetics, and at the same time have a better deformation transition, allowing the deformation at the center of the seat 1 to better transition to the position of the connecting member 2.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
