Description

Technical Field

[0001] The utility model relates to the technical field of rubber fatigue resistance detection, in particular to a rubber fatigue resistance tester. Background Art

[0002] Rubber fatigue testing is mainly used to test the physical properties of raw materials, finished products, and semi-finished products. It is used to test the tensile strength, compression strength, and bending strength of rubber, and obtain test results and test data such as elongation, elongation, stress, and strain. Therefore, a fatigue tester is required.

[0003] After searching, the Chinese patent with publication number CN215445956U discloses a multi-station rubber layer fatigue resistance testing equipment, including an equipment box, a pneumatic rod is plugged into the interior of the equipment box, and an air pump and a motor seat, a rotating motor, and an infrared sensor are plugged into one side of the pneumatic rod. The utility model has a reasonable structure. The pneumatic rod can lift the support plate when the rubber layer needs to be tested and place it. When the rubber layer is not in use, the support plate can be lowered to facilitate the movement of the entire equipment, avoiding the problem of inconvenience in placement and movement caused by the equipment being too large. The support plate can be quickly lowered immediately when a human body approaches during equipment operation, avoiding the problem of damage to the rubber layer during testing, which may cause damage to the rubber layer and cause harm to the human body. The handle can quickly move the entire equipment to the position where it needs to be placed. The bolt can adjust the position of the engaging plate to clamp the rubber layer.

[0004] Although the above solution can detect rubber, it still has some shortcomings during use. For example, it is difficult to perform tensile strength and bending tests on rubber at the same time during use, so the detection speed is slow.

[0005] To this end, we propose a rubber fatigue tester to solve the above problems. Utility Model Content
