AI Technical Summary
Technical Problem
In the prior art, threaded connections are prone to loosening under long-term vibration, impact or temperature changes, which affects the connection strength between the nut and the stud.
Method used
Design a planar connection fastening nut. The axial end face of the nut body is flat and has multiple concave holes. Combined with a conical disc and adhesive, the concave holes form a negative pressure adsorption and increase the contact area, thereby achieving multi-point anchoring and adhesive bonding.
Benefits of technology
It enhances the fit strength between the nut and the mounting surface, improves the fastening stability of flat products, prevents loosening, ensures uniform force distribution, and provides high fixing reliability.

Abstract
This utility model discloses a planar connection fastening nut and a planar fastening structure. It includes a nut body and an internal threaded hole. At least one axial end face of the nut body is a plane, with multiple recessed holes distributed on the plane. The planar fastening structure includes a bolt that mates with the nut body and a mounting surface that fits against the plane. The mating connection between the nut body and the bolt ensures a tight fit and fixation between the plane and the mounting surface. The plane and the mounting surface are bonded together with an adhesive material that shrinks in volume after curing. The advantages are: the end face of the nut body is designed as a plane with recessed holes; after the adhesive is applied and cured, a negative pressure adsorption effect is formed within the recessed holes, significantly enhancing the bonding strength between the nut and the mounting surface and preventing loosening.
