AI Technical Summary

Technical Problem

Existing technologies cannot effectively simulate the decline in airtightness of door frames due to the fatigue of sealing materials during use, and traditional static testing methods cannot meet the needs of dynamic testing.

Method used

A detection device comprising a base, support frame, sealing plate, positioning rod, airtight frame, water injection frame, contact plate, and control components was designed. The device deforms the door frame by applying stress, detects its dynamic airtightness in conjunction with the airtight frame, and controls the stress magnitude using a pressure sensor and an electric push rod.

Benefits of technology

It enables dynamic airtightness testing of door frame materials, which can more accurately assess changes in the airtightness of the door frame during use, and improve testing accuracy and reliability.
