Problems solved by technology

[0003] When carrying out riveting connection, it is first necessary to drill holes on the riveted parts. After the riveted parts are drilled, flashes and small raised parts are often easily formed around the nail hole. In addition, the caps of the rivet heads currently used for riveting Most of them are flat along the bottom surface. In this case, the riveting connection will be under-riveted or the surrounding of the rivet head and the riveted part will not be closely attached, which will affect the riveting strength and reduce the riveting quality.
If this kind of defect is to be eliminated, the riveted part must be drilled and then trimmed. Therefore, not only the operation process is increased, but also the work efficiency is reduced.

Abstract

The invention discloses an umbrella-shaped rivet. In rivet connection, after a riveted part is drilled, flash or small protrusion parts can happen to a rivet hole opening during rivet connection, andthe problems of influencing riveting strength, lowering riveting quality and the like exist. The umbrella-shaped rivet is mainly characterized in that the rivet is composed of a riveting body and a rivet rod, and the head of one end of the riveting body is of an umbrella-shaped structure. The umbrella-shaped rivet is simple in structure, convenient to use, sturdy and durable, and capable of beingwidely applied to the fastening fields of construction decoration, machine manufacturing and the like.

Description

technical field [0001] The invention relates to a rivet, in particular to an umbrella rivet. Background technique [0002] In the connection of steel structural parts, the method of riveting connection is also often used. [0003] When carrying out riveting connection, it is first necessary to drill holes on the riveted parts. After the riveted parts are drilled, flashes and small raised parts are often easily formed around the nail hole. In addition, the caps of the rivet heads currently used for riveting Most of them are flat along the bottom surface. In this case, the riveting connection will be under-riveted or the surrounding of the rivet head and the riveted piece will not be closely attached, which will affect the riveting strength and reduce the riveting quality. If this defect is to be eliminated, trimming must be carried out after the riveted part is drilled, so that not only increases the operation process, but also reduces the work efficiency. Contents of the ...
