Embodiment Construction

[0013] The present invention is described below in conjunction with accompanying drawing.

[0014] see figure 2 and image 3 As shown, the present invention is a welding nut 10 , which includes a flat piece 20 and a nut piece 30 . A perforation 21 is formed on the flat member 20 , and a welding protrusion 22 is formed at the bottom thereof. The upper end of the nut member 30 has a cylindrical cap portion 31 , the lower end has a joint portion 32 , and a screw hole 34 is formed in the center thereof, and the screw hole 34 axially passes through the cap portion 31 and the joint portion 32 . A disk 33 is disposed at the connection between the cap portion 31 and the joint portion 32 , the joint portion 32 is fixed in the through hole 21 of the flat piece 20 , and the bottom of the disk 33 abuts against the top of the flat piece 20 .

[0015] The welding protrusion 22 at the bottom of the flat piece 20 of the flat welding nut 10 of the present invention is welded on a workpiece...

Abstract

The invention discloses a welding nut, which comprises a flat piece and a nut piece, wherein a perforation is formed on the flat piece, and the bottom of the flat piece is provided with a welding boss; the upper end of the nut piece is provided with a cap part, and the lower end of the nut piece is provided with a combining part; a disc is arranged on a connecting part of the cap part and the combining part; the combining part is fixed in the perforation of the flat piece; and the bottom of the disc is pressed against the top of the flat piece. The invention has the advantages that: the welding nut is firmly and reliably welded, a workpiece is difficultly damaged, and the like.

Description

technical field [0001] The invention relates to a welding nut, in particular to the structural improvement of a flat welding nut, and belongs to the technical field of fasteners. Background technique [0002] The welding nut 50 of prior art, as specification attached figure 1 As shown, its bottom is provided with some raised welding spots 51, and the welding spots 51 are melted at high temperature, so that the welding nut 50 is welded on a workpiece, so that the welding nut 50 will not be screwed with the bolt. Shake. [0003] However, if the distance between the welding spots 51 is too small, when the welding nut 50 is welded on the workpiece, the welding spots 51 will be melted to cause local high temperature of the workpiece, causing damage to the workpiece. [0004] Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a flat welding nut with a more reasonable structure to overcome the defects in the prior art.
