Description

Anti-deformation precision positioning screw

Technical Field

The utility model relates to the technical field of screws, in particular to an anti-deformation precise positioning screw.

Background

The screw is a fastener commonly used in daily life and industry, is generally used for connecting two objects, is especially applied to some wood products, is an indispensable fastener in production and life, is large to aircraft carriers, airplanes and high-speed rails, is small to household appliances, and has no figure without screw; screws rely on friction between threads for tightening purposes, which is easily affected by external factors such as vibration, shock, etc.

Under some severe working conditions, some devices must be kept safe, stable and uninterrupted, the components of the device must have sufficient strength and stability, and as screws for connecting the components of each device, not only a certain deformation resistance but also a certain positioning and anti-falling ability are needed to meet the working requirements, therefore, we propose an anti-deformation precision positioning screw.
