Nut buckle

Abstract

The invention belongs to the field of automobile connecting pieces, specially relating to a nut buckle. The nut buckle provided by the invention comprises a cap, and a bolt portion, wherein an end surface on a side of the cap vertically extends outwards to form the bolt portion; profile of the bolt portion is like a tapered structure with a thin top and a thick root; elastic fins are arranged along a circumference of the bolt portion; an elastic movable gap is arranged between the elastic fin and an outer wall of the bolt portion; a side of the elastic fin is fixedly connected with the bolt portion; a length direction of a combined line of the elastic fin and the bolt portion extends along the length direction of the bolt portion; and a gap for containing a metal plate is reserved between the side of the elastic fin located at the root of the bolt portion and the end surface of the cap on the side. Elastic compression deformation between the elastic fin and the metal plate exists all the time, and is not direct rigid interference compression deformation in the conventional sense, therefore, the rigid scratch loss phenomenon between the bolt portion and the metal plate can be avoided obviously, finally, convenience for mounting is ensured while the rigid extrusion scratch phenomenon between the bolt portion and the metal plate can be avoided effectively; structure is simple; and service life is long.

Description

technical field [0001] The invention belongs to the field of automobile connectors, and in particular relates to a nut buckle. Background technique [0002] To fix two sheet metals with close distances on the car body, the usual method is to directly use ordinary nuts and screws to achieve the two fixings. The resulting poor installation appearance has brought many troubles to the manufacturer. In view of this, the applicant's application for an invention patent with the patent name "A Kind of Embedded Closed Nut" (Application No.: 201020574253.7) filed on October 22, 2010 disclosed the following technical content: figure 1 As shown, it is composed of a cap 1 and a trapezoidal post 2. The cap 1 and the trapezoidal post 2 are integrated, and a groove 3 is respectively arranged on the opposite sides of the connection between the two. The cap 1 and the trapezoidal The center of the post 2 is an oblong blind hole, and a rectangular blind hole is respectively arranged on opposi...

Problems solved by technology

When the above-mentioned application was used by the applicant for a long time, it was found that it guaranteed its quick assembly and beautiful appearance; In essence, it is an interference press-fit assembly, which often causes scratches and wear on the surface of the trapezoidal post due to the hard extrusion and sliding of the two, which ultimately affects its service life and installation stability.
