[0022] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 7 The utility model provides a technical solution: a buckle fixing mechanism for facilitating the disassembly and assembly of a waist support cushion, comprising a connecting piece 1, an elastic clamp 2 is integrally formed on the surface of the connecting piece 1, after the elastic clamp 2 penetrates the waist support cushion 3 and the ergonomic backrest 4, one end of the elastic clamp 2 blocks one side of the ergonomic backrest 4, and the waist support cushion 3 is clamped on the other side of the ergonomic backrest 4 by the connecting piece 1 and one end of the elastic clamp 2; the elastic clamp 2 is a flag-shaped plate structure, and the elastic clamp 2 There are two elastic clamps 2, which are symmetrically distributed about the center of the connecting piece 1; a limiting hole 9 is provided on the surface of the ergonomic backrest 4, and the limiting hole 9 is a "convex"-shaped round mouth, and the large-diameter slot of the limiting hole 9 is away from the lumbar cushion 3, and a perforation is provided on the surface of the lumbar cushion 3, and the perforation and the limiting hole 9 correspond one to one, and the aperture of the perforation is smaller than the plate diameter of the connecting piece 1. After the elastic clamp 2 passes through the limiting hole 9, one end of the elastic clamp 2 is blocked in the large-diameter slot of the slot of the limiting hole 9.

[0024] A pick-out groove 5 is provided at one end of the elastic clamp 2 away from the connecting piece 1, and the pick-out groove 5 is an oblong groove. A side groove 6 is provided on the surface of the elastic clamp 2, and the long side length of the side groove 6 is equal to the long side length of the elastic clamp 2, and the side grooves 6 on the surfaces of the two elastic clamps 2 are opposite; a rubber gasket 7 is fixed on the surface of the connecting piece 1, and the rubber gasket 7 is an "I"-shaped plate structure. After the elastic clamp 2 passes through the lumbar support cushion 3 and the ergonomic backrest 4, the rubber gasket 7 is clamped between the connecting piece 1 and the lumbar support cushion 3; a rubber connecting piece 8 is integrally formed on the surface of the rubber gasket 7, and the rubber connecting piece 8 is perpendicular to the rubber gasket 7, and the rubber connecting piece 8 corresponds to the side groove 6 one by one, and the rubber connecting piece 8 is fixed in the corresponding side groove 6, and the thickness of the rubber connecting piece 8 is equal to the depth of the side groove 6.

[0025] The reason why the extraction groove 5 is provided at the end of the elastic clamp 2 is to facilitate the removal of the elastic clamp 2. When the elastic clamp 2 passes through the limiting hole 9 to fix the waist cushion 3 on the ergonomic backrest 4, when the waist cushion 3 needs to be removed for replacement or cleaning, two fingers are respectively inserted into the extraction grooves 5 at the ends of the two elastic clamps 2, and the two fingers are closed. At this time, the two elastic clamps 2 are stretched to produce elastic deformation until the bent part of the end of the elastic clamp 2 is directly in front of the limiting hole 9, that is, the elastic clamp 2 is pulled out from the limiting hole 9, the elastic clamp 2 is pushed into the limiting hole 9, and then the connecting piece 1 is pulled out to remove the elastic clamp 2 from the surface of the waist cushion 3 and the ergonomic backrest 4. At this time, the waist cushion 3 is no longer fixed on the ergonomic backrest 4.

[0026] The reason for installing the rubber gasket 7 on the surface of the connecting piece 1 is that when the elastic clamp 2 passes through the limiting hole 9, one end of the elastic clamp 2 is clamped in one end of the limiting hole 9, and the connecting piece 1 and the lumbar cushion 3 clamp the rubber gasket 7 to produce elastic deformation. After the rubber gasket 7 rebounds, one end of the elastic clamp 2 is tightly pressed against the surface of the limiting hole 9, thereby effectively preventing the elastic clamp 2 from loosening and falling off in the limiting hole 9.

[0027] The rubber connecting piece 8 is integrally formed on the surface of the rubber gasket 7 and is embedded and fixed in the side groove 6. In this way, the rubber connecting piece 8 forms a coating connection structure between the elastic clamp 2 and the connecting piece 1, which effectively prevents the elastic clamp 2 from bending and breaking on the connecting piece 1.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
