Abstract

The invention discloses a composite detachable step riveting nut which comprises a riveting tube body. A nut rim body extending outwards is arranged at the head end of the riveting tube body. A large step hole is formed in the riveting tube body, and a threaded hole is formed in the bottom of the large step hole. The riveting tube body is sleeved with a liner lantern ring which is freely detached selectively according to the sizes of pre-drilled holes of riveted workpieces. An excellent riveting effect between the composite detachable step riveting nut and the riveted workpieces with different thicknesses and pre-drilled holes is achieved; the composite detachable step riveting nut has more superior mechanical strength compared with common riveting nuts; and the composite detachable step riveting nut can be used as a general riveting nut only by detaching the detachable liner lantern ring. The riveting nut can be applicable to a wider thickness range of the riveted workpieces, and cost is reduced for customers.

Description

technical field [0001] The invention relates to a riveting nut, in particular to a composite detachable stepped riveting nut. Background technique [0002] At present, rivet nuts have been widely used in the riveting of metal and non-metal plane and non-planar structural parts. Compared with general riveted fasteners, the other structure can be disassembled freely after the rivet nut is riveted, combining the functions of the rivet and the nut, which is convenient for maintenance and renewal. Therefore, it has been widely used in the electronics industry, shipbuilding industry, automobile, motor vehicle manufacturing, and aviation fields. [0003] However, when the existing riveting nuts are used for riveting a plurality of riveting workpieces with different pre-holes, the riveting conditions often lead to poor riveting. Contents of the invention [0004] The purpose of the present invention is to provide a composite detachable step riveting nut, which can make the rivet...
