AI Technical Summary
Existing flange bolts are inadequate in terms of anti-loosening and anti-corrosion performance. Straight teeth are prone to cracking, flanges are prone to deformation, and the screwing end is prone to corrosion, making disassembly difficult.
A screw structure was designed, including a flange end, a screw-on end, a threaded post, and a screw-on groove. The flange end is equipped with a serrated protective strip and a rubber gasket. The screw-on end is connected to a protective cover and a threaded mounting ring. An auxiliary clamping groove is used for stable disassembly. The serrated protective strip is designed with an inclination to disperse stress. The rubber gasket absorbs vibration energy. The protective cover isolates corrosive media.
It achieves stable fastening in vibration and corrosive environments, prevents tooth root cracking and tool slippage, extends service life, and is suitable for electronic equipment and medical devices that are sensitive to preload.
