AI Technical Summary
Existing flanges are difficult to pre-position and prevent loosening during installation, resulting in inconvenience during installation and easy loosening during use.
A powder metallurgy air conditioning compressor flange was designed, comprising a lower flange and an upper flange. The lower flange is provided with a pre-positioning structure and an anti-loosening structure. The pre-positioning structure achieves pre-positioning through a sliding connection of a rotating groove and a fixing ring. The anti-loosening structure achieves anti-loosening through a combination of mounting bolts, nuts, rings, and anti-loosening springs.
It enables convenient pre-positioning and anti-loosening of the flange, improving installation efficiency and operational stability.
