[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] A stable gasket assembly structure includes an assembly base and a gasket body, wherein the gasket body is inserted into the assembly base. In this embodiment, as... Figure 1 As shown, the assembly base is the chair leg of the seat, which includes several leg tubes 1. In this embodiment, a five-star leg is used as an example.

[0024] like Figure 1-3 As shown, the foot tube 1 is made of metal. A mounting groove 2 is provided on the lower side of the end of each foot tube 1. A metal positioning piece 3 is provided at the middle height position in the mounting groove 2. The positioning piece 3 divides the space in the mounting groove 2 into an inner cavity and an outer cavity 4. The side wall of the positioning piece 3 is welded to the inner side wall of the mounting groove 2.

[0025] Multiple opposing slots 5 are provided in the middle of the positioning piece 3, and several abutment rods 6 are formed between the slots 5. The inner cavity and the outer cavity 4 are interconnected through the slots 5. In this embodiment, as shown... Figure 2-3 As shown, there are two slots 5, forming a support rod 6 between them. The two slots 5 are symmetrical with respect to the support rod 6. The side of the two slots 5 away from the support rod 6 is set as a straight surface, and the side of the two slots 5 closer to the support rod 6 is also set as a straight surface. The two sides of the two slots 5 are set as curved surfaces.

[0026] like Figure 4 As shown, the gasket body includes a pad 7, an insert 8, and a plug 9. The pad 7 is used to contact the ground or other supporting surface, the insert 8 is fixedly connected to the surface of the pad 7, and the plug 9 is fixedly connected to the side of the insert 8 facing away from the pad 7. In this embodiment, the gasket body is a one-piece molded structure made of plastic.

[0027] The insert 8 is used to install in the outer cavity 4 of the mounting slot 2. Two inserts 9 first extend into the outer cavity 4 and then are respectively inserted into the two slots 5, with one end finally extending into the inner cavity. The cross-section of the insert 9 is set to be flat in the middle and curved on both sides, matching the shape of the slot 5. When the insert 9 is inserted into the slot 5, the insert 9 undergoes slight deformation, forming an interference fit. One side of the insert 9 abuts against the curved surface of the slot 5, and the two ends of the side of the insert 9 abut against the abutment rod 6. The slot 5 and the abutment rod 6 simultaneously apply opposing pressure to the insert 9, thereby clamping the insert 9 and making the installation of the gasket body more secure. By setting the cross-section of the insert 9 to be curved, the structural support strength of the insert 9 can also be increased, making the insert 9 less likely to break during and after insertion. Several locking ridges 10 are integrally provided on the surfaces of the two inserts 9 that are far apart from each other, along the insertion direction of the insert 9. In this embodiment, each insert 9 has three locking ridges 10. A first inclined surface 13 is provided at the end of the insert 9. The first inclined surface 13 makes it easier to position the insert 9 and insert it into the slot 5.

[0028] When the insert 9 is inserted into the slot 5, each insert 9 simultaneously abuts against the abutment 6 and the side wall of the slot 5, with the abutment 6 positioned between two adjacent locking edges 10. At this time, the insert 8 is embedded in the mounting groove 2, and the pad 7 covers the mounting groove 2.

[0029] Several fastening strips 11 are integrally formed on the outer wall of the insert 8, and the fastening strips 11 abut against the inner wall of the mounting groove 2. By setting the fastening strips 11, the volume of the insert 8 can be reduced to a certain extent. While saving material costs, the fastening strips 11 are independent and smaller in size, and are more prone to slight deformation than a single piece of insert 8. The slight deformation of the fastening strips 11 forms an interference fit, making the installation of the insert 8 more secure. The fastening strips 11 also include a second inclined surface 12 at the end, which makes it easier for the insert 8 to be inserted into the mounting groove 2.

[0030] Several material-saving grooves are also provided on the insert 8 to save material for the gasket body and optimize costs.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
