Problems solved by technology

[0009] But, because this rivet nut is connected with the chuck by mutually detachable nut body, and between the nut body and the chuck is only connected with the chuck through the card body of the elastic jaw at the bottom of the nut body, in the process of screwing in the bolt, The deformation of the claws will easily cause the card body to fall off from the chuck, resulting in the situation that the nut body cannot be fixed

Abstract

The invention provides a riveting nut which is provided with a nut body. The inner wall of the nut body is provided with an internal screw thread; the riveting nut also comprises a connecting part; a first end of the connecting part is fixed on the nut body; the connecting part is of a spiral shape; the connecting part extends along the axial direction of the nut body; the riveting nut is also provided with a fixing part; the fixing part comprises a fixing plate and a positioning ring positioned on one end face of the fixing plate; a second end of the connecting part is fixed on the positioning ring; and the fixing part is provided with a through hole running through the fixing plate and the positioning ring. The riveting nut provided by the invention can be conveniently arranged on a board which is inconvenient to place a common nut, is firmly connected with a bolt and is difficult to fall off.

Description

technical field [0001] The invention relates to the field of assembly tools, in particular to a riveting nut. Background technique [0002] The equipment used in people's life and production process is usually composed of multiple parts, and the fixed connection between multiple parts is usually realized by using fixed workpieces. In addition, when people realize the connection between two objects, they often need to use fixed workpieces. For example, people need to install locks on the door, usually offer threaded holes on the door, and set the through hole for the bolt to pass on the lock, use the bolt to pass through the through hole and then screw into the threaded hole, so there is a gap between the lock and the door. The fixed connection is realized by bolts. [0003] In addition to using threaded connections, common fixed connection methods include riveting, gluing, welding, etc. People choose the appropriate connection method according to the needs of actual use. ...
