Description

Core-pulling riveting nut Technical Field The utility model relates to the technical field of nuts, in particular to a loose core riveting nut. Background The press-riveting nut is also called a rivet nut and is a self-fastening nut which is applied to a thin plate or a metal plate, the end part of the conventional press-riveting nut, which is easy to press deflection and inclined guide pillar nut, is difficult to be attached to a plate when in riveting installation, the center line of threads is not perpendicular to the surface of the plate, and the press-riveting nut is easy to pop up to hurt people in the installation process. Through retrieval, in the application book with the patent publication number of CN104100624A, a loose core riveting nut assembly and a riveting method are disclosed, the loose core riveting nut assembly comprises a riveting nut and a riveting core rod, the riveting nut is connected with the riveting core rod through a thread pair, one end of the riveting nut is a thick-wall round nut, the other end of the riveting nut is a thin-wall riveting ring, a group of anti-slip ribs are arranged on the connecting end face of the thick-wall round nut and the thin-wall riveting ring, a passing groove is arranged on the connecting corner of the thick-wall round nut and the thin-wall riveting ring, a square boss spiral arm is arranged at one end of the riveting core rod, welding is not needed, riveting pressure is controllable, and slipping phenomenon is prevented; However, due to the arrangement of the riveting nut and the riveting core rod, when the riveting nut is installed, the installation firmness is low, the using effect is poor, and meanwhile, due to the arrangement of the riveting nut, external rainwater easily flows into the lower part from the riveting nut, so that the waterproof sealing performance is low, and the practicability is low. Therefore, we propose a blind rivet nut. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a loose core riveting nut, which solves the problems of poor use effect and low waterproof sealing performance of the existing device. The core pulling riveting nut comprises a mounting plate and a rivet pulling gun, wherein a mounting hole is formed in the top surface of the mounting plate; The installation hole is internally provided with a riveting cylinder with the specification matched, the top surface of the riveting cylinder is fixedly provided with a fixing head with the specification matched, the top surface of the fixing head is provided with a deformation cavity penetrating into the riveting cylinder, the bottom of the deformation cavity is provided with an internal thread groove with the specification matched, the outer wall of the riveting barrel is provided with a deformed tooth socket positioned on the bottom surface of the fixed head, a core pulling rod with specification matching is assembled in the deformed cavity, and the outer wall of the core pulling rod is provided with threads matched with the internal thread specification; The bottom surface of the fixed head is provided with an annular groove, a rubber sealing ring with the specification matched with the groove is arranged in the groove, the top surface of the fixed head is provided with a rubber sealing sleeve with the specification matched with the groove, and the bottom surface of the riveting barrel is fixedly provided with a fixed cover with the specification matched with the groove.
