TECHNICAL FIELD

[0001] The utility model relates to rubber aging test technical field, concretely relates to a rubber ozone aging test device. BACKGROUND

[0002] Rubber is an important material widely used in industry, transportation, construction and many other fields, and its products often face the threat of ozone in actual use environment. Ozone has strong oxidizing property and can chemically react with rubber molecules, leading to aging phenomena such as surface cracking, hardening and loss of elasticity of rubber. In order to effectively evaluate the ozone aging resistance of rubber materials, a rubber ozone aging test device has become an indispensable tool in research and development, production and quality control.

[0003] The traditional rubber ozone aging test device has many shortcomings. In terms of sample clamping, most of them can only be used for rubber samples of specific shape and size, and have poor universality. When faced with diversified rubber product samples, the clamps need to be frequently replaced or adjusted, which is tedious and time-consuming. Moreover, the traditional clamps are inconvenient to disassemble and assemble in the test box, and the operator often needs to perform complex disassembly and assembly operations when taking and placing the samples, which greatly affects the work efficiency. In addition, the traditional test device can usually only provide relatively single test conditions, such as the sample being in a static fixed position or a simple unidirectional stretching state, and it is difficult to simulate the multi-angle ozone erosion and dynamic force change experienced by rubber products in actual complex use scenarios, which makes the test results deviate greatly from the actual application.
