AI Technical Summary

Technical Problem

Existing multi-layer filter box fixing devices are difficult to disperse stress under complex working conditions such as high pressure and vibration, resulting in loose fixing parts and displacement of the filter box. In addition, traditional rigid limiting methods cannot buffer the impact force of the equipment, posing safety hazards.

Method used

It adopts a combined structure including a fixing frame, connecting plate, nut, screw, slider, support plate, spring and limiting plate. It achieves stable fixation of multi-layer box through elastic limiting and expansion components, disperses stress by utilizing the elastic deformation and restoring force of spring, and achieves quick connection and expansion by combining with the snap-fit ​​structure.

Benefits of technology

It improves the stability and flexibility of multi-layer filter boxes under complex working conditions, prevents equipment displacement and media leakage, and enhances the applicability and ease of installation of the fixed device.
