[0065] The present invention will be further explained below with reference to the accompanying drawings.

[0066] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. Any changes made by those skilled in the art after reading the specification of the present invention, as long as they are within the scope of the claims, will be protected by patent law.

[0067] Example 1

[0068] A type of seating that is easy to assemble and disassemble, such as Figure 1 As shown, the seating consists of a seat plate 1 and a chair frame 2. The seat plate 1 is covered with a cushion, which includes an inner layer made of polyurethane foam and an outer layer made of PU leather. Furthermore, the seat plate 1 is integrally formed with the backrest panel using steel and is designed according to an ergonomic profile to provide elastic support for the user's lower back.

[0069] like Figure 2 As shown, the chair frame 2 is assembled from a first support 21 and a second support 22. The first support 21 includes a base plate 211 and a base plate support 212 located below the base plate. The base plate support 212 has a support mounting portion 2121, which is formed by bending the lower end of the base plate support 212 away from the second support 22.

[0070] like Figures 2-4 As shown. The second bracket 22 includes a tray 221, a base plate 223, and a tray support 222 located below the tray and based on the base plate. The base plate 223 has a base plate mounting portion 2231.

[0071] like Figures 2-3 As shown. The support mounting portion 2121 is provided with a first fastener through hole 21a. The substrate 211 is provided with a second fastener through hole 21b and a third fastener through hole 21c.

[0072] like Figures 2-4 As shown. The base plate mounting part 2231 is provided with a first corresponding hole 22a that is aligned with the hole position of the first fastener through hole 21a. The support plate 221 is provided with a second corresponding hole 22b that is aligned with the hole position of the second fastener through hole 21b.

[0073] The chair frame 2 is formed by assembling the first bracket 21 and the second bracket 22 by installing fasteners in the first fastener through hole 21a and the first corresponding hole 22a, and by installing fasteners in the second fastener through hole 21b and the second corresponding hole 22b.

[0074] In this embodiment, the chair frame 2 is used to directly mount the seat plate 1. Therefore, the third fastener through hole 21c is aligned with the mounting hole of the seat plate 1 for mounting the fastener.

[0075] As shown in Figures 2-3 , the substrate support body 212 is arranged closer to the first end 211x of the substrate 211 relative to the second end 211y of the substrate 211. As shown in Figure 1 , the first fastener through hole is arranged at a first distance from the substrate support body, which is smaller than a second distance of the first corresponding hole from the support plate support body. Further, the seat further comprises a first chair leg 41 integrally connected with the first support 21 and a second chair leg 42 integrally connected with the second support 22. This arrangement facilitates the stacking of the first support 21 and the stacking of the second support 22, thereby saving space. Moreover, when the chair frame is loaded with weight, the offset mounting of the substrate support body 212 and the support plate support body 222 can provide a certain elastic support to the substrate 211, thereby relieving the hard touch feeling caused by the high rigidity chair frame in use and improving the use comfort of the product.

[0076] Further, as shown in Figure 4 , the support plate support body 222 is integrally connected with the bottom plate 223. Specifically, the support plate support body 222 integrally connected with the bottom plate 223 is formed by bending a rectangular plate upward after cutting the bottom plate 223 along the long side-short side-long side of the rectangular trajectory. The support plate 221 is welded to the support plate support body 222. Specifically, the support plate 221 welded to the support plate support body 222 is formed by welding the support plate 221 to the bent portion of the support plate support body 222 away from the bottom plate 223.

[0077] Figure 5 As shown in the figure, the first support is in a stacking state during storage and transportation. Among them, the first positioning part 213 located below the substrate is matched with the third fastener through hole 21c on the substrate of the adjacent first support below, realizing temporary locking to avoid relative displacement during storage and transportation.

[0078] Figure 6 As shown in the figure, the second support is in a stacking state during storage and transportation. Among them, the second positioning part 224 located above the bottom plate is matched with the second corresponding hole 22b of the adjacent second support (upside down) above, and the second positioning part 224 of the upside-down second support is matched with the second corresponding hole 22b of the adjacent second support (normal) below, realizing temporary locking of the matched group. At the same time, the third positioning part 225 located below the bottom plate is matched with the first corresponding hole 22a of the adjacent second support (upside down) below, and the third positioning part 225 of the upside-down second support is matched with the first corresponding hole 22a of the adjacent second support (normal) above, realizing temporary locking between groups in the matched group. Through the temporary locking within and between groups, relative displacement during storage and transportation is avoided.
