Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a blind hole pressure riveting nut column using step positioning. Background Art

[0002] A blind hole self-riveting nut column is a device used to fix nuts on thin plates or surfaces that cannot be accessed from the other side. It usually consists of a self-riveting nut and a nut column. The nut column is fixed to the surface of the workpiece by self-riveting, thereby providing a reliable threaded connection point. For example, CN219388397U disclosed on the Chinese patent website is a blind hole self-riveting nut column using step positioning. It includes a retaining ring, a concave ring and a stud. The front end of the stud is provided with a step with a diameter smaller than the stud. The step is tubular and connected to the stud. A threaded portion is provided on the inner wall together for threading screws. A deformation cavity is formed in the stud and at the end of the threaded portion. Its function is to accommodate the concave ring and the stud when the pressure riveting is performed. A small amount of inward deformation occurs locally near the concave ring to avoid direct distortion of the threaded portion due to pressure riveting; a step protruding from the front end of the stud is provided as a positioning mechanism for screw-on parts such as hollow tube screw-on handrails, which plays a radial positioning role for the screw-on part during the screwing process, and plays a radial supporting role for the screw-on part after screwing, sharing the burden of the screws and thus improving the service life of the screw-on structure. However, the thickness of the plate inserted into this type of blind hole pressure riveted nut column is fixed, which is not suitable for plates of different thicknesses and has weak applicability. Therefore, a blind hole pressure riveted nut column using step positioning is proposed. Utility Model Content
