Background

At present, the performances and functions of many products are seriously homogenized, and products of different brands and models can only show the differentiation of the products by means of different appearance designs.

At present, in order to assist the completion of the above-mentioned differential design, to improve the aesthetic feeling and technological sense of the appearance of the product, often install metal decoration on the plastic shell of the product itself, so, from the visual perspective, the whole product has metal feel, and from cost and production degree of difficulty also have to reach fine balance. The metal decorating part is generally thinner, the metal layer is only 1mm or a few mm, no matter the metal layer is limited by aesthetic requirements or actual thickness, screw holes are usually not formed in the metal layer, so that the metal decorating part and a plastic part are fixedly installed through glue or glue-adhered nuts, and then the nuts are adhered to the decorating part through connection between the nuts and a screw rod, as shown in fig. 1, the nuts are adhered to the decorating part through dehydration, and then the nuts are connected with the screw rod, and the two modes have the same defect that the stability of a connecting structure mainly depends on the glue, and the glue is influenced by various factors such as a gluing process, a gluing temperature, a gluing time length, the performance of the glue, and the like, so that the metal decorating part is relatively complex in assembly, has a certain possibility of falling off, influences the quality stability of products, and risks of customer complaints and compensation occur due to the falling of the metal decorating part.

In summary, it is desirable to provide a thin-walled metal trim with nuts that has good stability in the connection structure, which has practical application value and use requirements in the art.
