Description

Technical Field

[0001] This utility model relates to the field of glass testing technology, specifically a glass bending test fixture. Background Technology

[0002] During the glass manufacturing process, due to the inherent fragility of glass products, bending resistance tests are necessary after production to ensure their quality meets requirements. Traditional testing methods involve workers placing the glass on a workbench, manually bending it, pressing it down with a pressure plate, and then allowing it to remain stationary for a specified time as required by the test. However, this traditional method suffers from poor stability, easily causing the glass to wobble during the test, thus affecting the measurement results and causing errors. Furthermore, workers need to frequently apply manual pressure to the glass to bend it and perform static tests, which is not only labor-intensive but also inefficient. Therefore, providing a glass bending test fixture is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
