AI Technical Summary

Technical Problem

Traditional screws may generate magnetic interference in a strong magnetic field environment, affecting equipment operation and imaging quality. At the same time, they are prone to loosening under external force, resulting in unstable installation and increasing maintenance difficulty.

Method used

A stainless steel screw with a non-magnetic hexagonal head and non-magnetic bolt was designed. Combining a limiting rod, a hollow cylinder, and a spring structure, the screw is stably fixed by the interlocking cooperation of the limiting rod and the hollow cylinder, and is easy to disassemble by the design of the lifting plate and the pulling plate.

Benefits of technology

Preventing screws from loosening in strong magnetic field environments ensures installation stability and easy disassembly, reduces maintenance difficulty, and improves the operational reliability of the equipment.
