[0002] Rubber is an elastic polymer that can be obtained from the sap of some plants or artificially produced. Both have a wide range of applications and products, such as tires, gaskets, etc., making it an important economic crop.

[0003] At present, rubber pads are often used on the bottom of tables and equipment in daily life to play a role in wear resistance and noise reduction. However, after the rubber pads are produced, their dynamic wear resistance in actual use cannot be known. At present, manufacturers will manually bend them for dynamic wear resistance quality inspection before leaving the factory, but the manual inspection standards are not up to standard and cannot be unified. For this reason, we propose a dynamic fatigue resistant rubber pad test device to solve the above problems. Utility Model Content
