Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific drawings.

[0021] Such as Figure 1 to Figure 6 As shown: the expansion rivet includes groove 1, nail body 2, nail core body 3, nail body head 4, first hole 5, crimping line 6, fracture part 7, anti-slip groove 8, nail core head 9, The third hole 10, the workpiece A11, the workpiece B12, the clamping portion 13, the second hole 14, the cylinder 15, and the like.

[0022] Such as figure 1 , figure 2 As shown, the present invention includes a nail body 2 and a nail core positioned in the nail body 2, the nail body 2 is provided with a first hole 5 distributed axially along the nail body 2, and one end of the nail body 2 is protruded with a The nail body head 4, the outer surface of the nail body head 4 is an oblate spherical surface. The nail body head 4 of this oblate spherical surface looks better after the riveting is completed, especially the surface is relatively smooth, and there...

Abstract

The invention relates to an expansion type pull rivet, which includes a nail body and a nail core, and is characterized in that: the nail body is provided with a first hole, one end of the nail body protrudes from a nail body head, and the outer diameter of the nail body head is larger than the nail body The outer diameter of the nail body head is provided with a second hole, the second hole communicates with the first hole, the diameter of the second hole is smaller than the diameter of the first hole, and a step is formed at the junction of the second hole and the first hole The mandrel comprises a mandrel body and a mandrel head, and the mandrel head protrudes from one end of the mandrel body, and a cylinder is provided on the mandrel body corresponding to the head of the mandrel, and the body of the mandrel One end is connected with the mandrel head, and the other end of the cylinder is connected with the mandrel body through the clamping part and the fracture part; hole and a second hole in the head of the nail body. The invention solves the problem of insufficient drum shape after common rivets are riveted; it can prevent loosening and falling off after vibration, and the riveting is more firm.

Description

technical field [0001] The invention relates to a rivet, in particular to an expansion-type blind rivet used for riveting aerospace, automobiles, electric appliances, architectural decoration, machinery manufacturing and other fields requiring fastening. Background technique [0002] At present, most products in the field of fastening are fastened with ordinary rivets and screws. Due to the limitations of the structure of this product, there is insufficient strength after fastening and it is easy to loosen and fall off, thus affecting the fastening effect, and The product is single, cannot be applied mechanically, and is labor-intensive and time-consuming, thus affecting the overall quality and performance of the product. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an ingenious and reasonable structure expansion type blind rivet, which can avoid the adverse consequences of the workpie...
