Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass, in particular to a glass fragment state testing fixture. Background Art

[0002] Tempered glass is a safety glass, and its safety is very important. The overall stress distribution of tempered glass needs to be tested with fragments to obtain the results. The purpose of the test is to evaluate the possibility of injury caused by fragments when the tempered glass is broken. Therefore, in the production of tempered glass or in the performance test of tempered glass by the testing agency, the fragment test is one of the important tests. By checking the number, size and shape of fragments within the specified size, it is determined whether the product meets the standard. For example, according to national standards, after 3mm thick tempered glass is broken, the number of fragments in the specified area (any 50x50mm) should be no less than 30, and 4-12mm thick tempered glass should be no less than 40. A small amount of long strip fragments are allowed, and the length does not exceed 75mm.

[0003] At present, the existing fixtures for fixing glass samples are relatively complicated and not easy to operate, and the observation and reading of test data are all done manually. Since the shapes of broken glass fragments are irregular and there are a large number of them, if the fragments are observed, identified and read manually, not only is the workload heavy, but it is also easy to get tired after a long time. It is also easy to be affected by many factors such as personality, emotions and vision, which leads to errors and affects the accuracy of the test results. Utility Model Content
