Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, an embodiment of the present invention provides a nut post assembly, which includes a nut 1, a fixing stud 2, a nut post 3, a nut post head 4 and an inner cavity 5, wherein the nut 1 is screwed on the fixing stud 2, the fixing stud 2 passes through a sheet metal component, so that the nut post 3 abuts against a prefabricated mounting hole of the sheet metal component, the fixing stud 2 is fixedly connected with one end of the nut post 3, the other end of the nut post 3 is fixedly connected with the nut post head 4, when the nut 1 is rotated, the position of the nut 1 is fed along the direction of the fixing stud 2 and abuts against the sheet metal component, during the rotation of the nut 1, since the nut 1 and the fixing stud 2 form a screw pair, the positions of the nut 1 and the nut post head 4 can be close to each other, and then the nut post head 4 is drawn into the prefabricated mounting hole of the sheet metal component by the fixing stud 2, so that the periphery of the hole is plastically deformed, the deformation is squeezed around the nut stud 3, which in turn produces a locking effect. An inner cavity 5 is arranged inside the nut column head 4, and a bolt is inserted into the inner cavity 5.
According to the utility model discloses a specific embodiment, inner chamber 5 includes exocoel 51, tool withdrawal groove 52 and screw hole 53, the inside exocoel 51 that is provided with of nut column cap 4, exocoel 51 sets up in tool withdrawal groove 52 one end, and exocoel 51 offsets with the bolt, the other end of tool withdrawal groove 52 is provided with screw hole 53, and the bolt passes through screw hole 53 and nut column 3 spiro union is fixed, screw hole 53 is through tool withdrawal groove 52 and exocoel 51 intercommunication, and the aim at that sets up tool withdrawal groove 52 is convenient for tool withdrawal man-hour, can guarantee to lean on tightly with adjacent part when the assembly simultaneously. The threaded hole 53 is screwed and fixed with the bolt, thereby preventing the bolt from falling off. The outer cavity 51 abuts against the bolt, and the purpose of the outer cavity is to improve the shear stress performance of the bolt at the position of the thicker part of the bolt.
According to the utility model discloses a concrete embodiment, its characterized in that, exocoel 51 includes first fillet 511, hole 512, second fillet 513 and taper hole 514, first fillet 511 sets up and follows outside hole 512 to the bolt enters into exocoel 51, hole 512 is through second fillet 513 and taper hole 514 one end intercommunication, the taper hole 514 other end is provided with tool withdrawal groove 52. Therefore, the taper hole 514 can abut against the bolt, so that the connection strength of the nut column 3 and the bolt can be ensured, and the pressure resistance of the bolt is improved.
According to a specific embodiment of the present invention, the screw thread direction of the fixing stud 2 is opposite to the screw thread direction of the screw hole 53. This makes it possible to reverse the screwing direction of the bolt and the nut 11, and when screwing the bolt into the screw hole 53, the nut 1 screws inward, thereby achieving the purpose of preventing the nut 1 from falling off.
According to a specific embodiment of the present invention, the taper ratio of the nut post 3 is 1/15. Because the nut post 3 has the tapering, consequently can make nut post 3 can overlap in the prefabricated hole to be convenient for the fastening of nut post subassembly.
The utility model discloses use as follows:
at first, insert fixing stud 2 and establish into the panel beating prefabricated hole, later with nut 1 screw in to fixing stud 2 on, wrench movement fixing stud 2 makes nut 1 along stud 2 rebound, then makes nut 1 offset with the sheet metal component, nut post 3 enters into the panel beating prefabricated hole under fixing stud 2's drive to at panel beating prefabricated hole internal fixation.
The utility model discloses solid structure, practical convenient draws in the panel beating prefabricated hole with nut post 3 through nut 1 and the 2 screw-driven modes of fixed double-screw bolt, has solved from this among the prior art because the problem that can't impress the nut in the sheet metal component that place restriction or sheet metal component structure special and lead to.
