[0001] The utility model relates to the technical field of zipper production testing, in particular to a zipper use endurance testing device. Background Art

[0002] The zipper endurance refers to the degree to which the zipper can withstand long-term, high-frequency opening and closing operations. By conducting an endurance test on a zipper, the durability and life of the zipper can be evaluated to ensure that it can work normally and has a long reliability in actual use; usually, the zipper endurance test will simulate the situation of users frequently opening and closing the zipper in daily life or work, repeatedly pull the zipper through mechanical equipment, record the number of times or time the zipper is used, and observe whether the zipper is damaged, deformed or failed.

[0003] The existing zipper endurance testing device tests the zipper's endurance performance by repeatedly pulling the zipper through mechanical equipment during the test. The existing zipper will complete the test within a specified time for production efficiency. However, the zipper will experience different seasonal changes during use, and will undergo different changes under different ambient temperatures. As a result, the existing testing device cannot complete the test after different changes in different environments within the specified test time, thereby reducing the accuracy of the zipper test. To this end, we propose a zipper endurance testing device. Utility Model Content
