DETAILED DESCRIPTION

[0022] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0023] For example, Figures 1-3As shown, a combination structure of mesh fabric and seat frame includes a seat frame 1 and a mesh fabric component 2 disposed on the inner side of the seat frame 1. The seat frame 1 has a mesh fabric mounting groove 11 on the outer side of the seat frame 1. The opening 12 of the mesh fabric mounting groove 11 is provided with a plurality of anti-slip limiting parts 3 on the side near the inner side of the seat frame 1. An installation gap 4 is formed between one end of the anti-slip limiting part 3 and the other side of the opening 12 of the mesh fabric mounting groove 11. The outer edge of the mesh fabric component 2 is provided with a mesh fabric fixing part 5 that can be inserted into the mesh fabric mounting groove 11 through the installation gap 4, and the mesh fabric fixing part 5 is abutted against the inner side of the anti-slip limiting part 3. The mesh fastener 5 can accurately position the mesh component 2, ensuring that the mesh component 2 will not shift during installation. It can quickly and evenly fix the mesh component 2 to the seat frame 1, thus saving installation time. In addition, the mesh fastener 5 has strong tensile strength and can withstand various tensile and tension forces on the mesh component 2 during use, preventing the mesh component 2 from falling off the seat frame 1, thereby extending the service life of the mesh component 2 and the seat.

[0024] like Figure 1 As shown, the seat frame 1 has a ring-shaped frame structure, and has a ring-shaped frame top surface 13 on the outer side of the upper end of the seat frame 1.

[0025] like Figure 2 As shown, the mesh installation groove 11 is annular and vertically arranged on the inner side of the top surface 13 of the frame.

[0026] The frame top surface 13 has an outer transition surface 14 on one side of the opening 12 of the mesh mounting groove 11, and an inner transition surface 15 on the other side of the opening 12 of the mesh mounting groove 11. The width of the outer transition surface 14 is greater than the width of the inner transition surface 15. During installation, the mesh component 2 conceals the inner transition surface 15 and works in conjunction with the outer transition surface 15 to make the surface of the seat frame 1 look cleaner and more aesthetically pleasing, avoiding the clutter that might result from exposed edges of the mesh component 2. Simultaneously, the inner transition surface 15 serves as a guide during installation.

[0027] Combination Figure 2 and Figure 3 As shown, the outer edge of the mesh fabric component 2 is fixedly connected to the mesh fabric fixing component 5. After passing through the installation gap 4, the mesh fabric component 2 covers the transition surface 15 inside the frame and extends inward toward the seat frame 1. The installation gap 4 is used for installing the mesh fabric component 2 and the mesh fabric fixing component 5 into the mesh fabric mounting groove 11.

[0028] Among them, the anti-detachment limiting part 3 is arranged sequentially on the side of the opening 12 of the mesh installation groove 11 near the inner transition surface 15 of the frame and extends towards the outer transition surface 14 of the frame, and the outer side of the anti-detachment limiting part 3 is flush with the inner transition surface 15 of the frame.

[0029] Specifically, the mesh fixing member 5 is annular and formed by connecting the mesh fixing strips 51 end to end, the thickness of the mesh fixing strips 51 is not less than the width of the installation gap 4.

[0030] Further, the mesh fixing strips 51 are rectangular in cross section, the circumferential outer edge of the mesh member 2 extends from one side of the mesh fixing strips 51 to the other side, and the mesh member 2 and the mesh fixing strips 51 are connected by sewing. The mesh fixing strips 51 are made of hard plastic material, the mesh fixing strips 51 are inserted into the mesh mounting groove 11, and the upper end of the mesh fixing strips 51 abuts against the anti-disengagement limiting portion 3.

[0031] As shown in Figure 1 The frame top surface 13 has front and rear side portions 16 and left and right side portions 17, the left and right side portions 17 are higher than the front and rear side portions 16, and the front and rear side portions 16 and the left and right side portions 17 are connected by a curved surface.

[0032] The seat frame 1 has a chair frame base 18 recessed inwardly in the circumferential direction, the frame top surface 13 has a plurality of inclined portions 19 extending downwardly and inclined toward the seat frame 1 in the circumferential direction, and the frame outer transition surface 14 has an arc-shaped transition portion 20 at the circumferential outer edge.

[0033] The principle of the embodiment is that:

[0034] The mesh fixing member 5 is installed on the circumferential outer side of the mesh member 2, the edge of the mesh member 2 wraps the mesh fixing member 5 and is fixed by sewing, the mesh fixing member 5 is arranged in the mesh mounting groove 11 through the installation gap 4, and the upper end of the mesh fixing member 5 abuts against the anti-disengagement limiting portion 3, so that the mesh fixing member 5 cannot disengage from the mesh mounting groove 11. Therefore, the cooperation of the mesh fixing member 5 and the anti-disengagement limiting portion 3 can ensure that the mesh member 2 is tightly combined with the seat frame 1, can withstand long-term use and repeated pressure, and is not prone to loosening, disengagement or tearing, thereby prolonging the service life of the seat.

[0035] The specific embodiments described herein are merely illustrative of the spirit 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 them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
