[0003] However, due to the existing single buckle soundproof rubber block products, which use ordinary square holes, rectangular or round holes, they will rotate under the impact of electrophoresis, and the position deviation will cause the seal to fail. The existing buckle is installed on the sheet metal along the installation There is a gap in the direction fit, which will cause shaking in this direction, which is not conducive to the fixing of the product. The existing design cannot be fool-proof when the sheet metal features are not obvious.

Embodiment 1
[0021] like Figure 1-3 As shown, a mounting buckle suitable for expansion rubber products with special-shaped mounting holes, including sheet metal 1 and buckle 2,
[0022] There is a special-shaped hole 3 on the sheet metal 1, the special-shaped hole 3 has a convex structure, and the buckle 2 is snapped into the special-shaped hole 3;
[0023] The buckle includes a mounting base 201, a buckle spring 202, an upper limit 203 and a lower limit 204. The buckle spring 202 is installed on the side wall of the mounting base 201, and the upper limit 203 and the lower limit 204 are respectively installed on the mounting base. the side walls and bottom of 201;
[0024] The buckle elastic piece 202 is combined with the local elastic limit of the left port of the special-shaped hole 3 , and the upper limit 203 and the lower limit 204 are combined with the right port of the special-shaped hole 3 rigidly.
[0025] Use the convex special-shaped hole 3 to prevent the possibility of rotati...

The invention provides an installation buckle of an expansion rubber product and suitable for a special-shaped installation hole, and relates to the field of automobiles. The installation buckle comprises a metal plate and a buckle. According to the installation buckle, a convex special-shaped hole is used, the possibility of rotation is avoided structurally, axial symmetry modeling is carried outalong a dotted line, expansion rubber blocks on the left side and the right side (an automobile is provided with a left side bypass metal plate and a right side bypass metal plate, and the left sideand the right side are symmetrical along a ZX plane) can be universal (i.e. the expansion rubber blocks can be assembled on the left side and the right side mutually), asymmetric modeling is carried out along a solid line, fool-proofing can be realized, and the expansion rubber blocks can only be installed in a specific direction and cannot be installed in the reverse directions; the matching in the installation direction is a design concept with gaps, local elastic limiting is used, and the local elastic limiting and the rigid limiting are combined, so that the installation matching is tightand shaking is avoided.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a mounting buckle for expansion rubber products suitable for special-shaped mounting holes. Background technique [0002] The expansion glue is installed in the bypass cavity of the body-in-white in the welding workshop, and undergoes electrophoresis baking in the painting workshop to produce a chemical change: foaming, and after foaming, the cavity section and the installation hole are sealed, thereby blocking the sheet metal bypass cavity The medium air transmission path, and absorb vibration and air noise, to achieve the function of sound insulation and noise reduction. [0003] However, due to the existing single buckle soundproof rubber block products, which use ordinary square holes, rectangular or round holes, they will rotate under the impact of electrophoresis, and the position deviation will cause the seal to fail. The existing buckle is installed on the sheet metal along the...
