Description

Technical Field

[0001] The utility model relates to the technical field of rubber material testing devices, in particular to a rubber sealing fatigue testing platform with high safety. Background Art

[0002] Rubber seals are a type of rubber product widely used in sealing technology. They are a type of polymer compound with extremely high elasticity. In a wide temperature range, a small stress in different media will produce a large deformation. This deformation can provide contact pressure, compensate for leakage gaps, and achieve the purpose of sealing. At present, fatigue test benches on the market mainly use continuous flexing to perform fatigue tests on rubber seals, that is, the performance of rubber seals is indicated by testing the number of times the rubber seals are subjected to repeated flexing. Since rubber seals are subjected to repeated flexing during the test, the rubber seals may detach from the test bench due to long-term repeated stress, and in order to adapt to rubber seals of different sizes, it may be necessary to replace fatigue test benches of different models to complete the test. Therefore, it is necessary to propose a rubber seal fatigue test bench to solve the above problems.

[0003] In order to solve the above technical problems, a Chinese utility model patent with authorization announcement number CN216978332U discloses a rubber seal fatigue test bench, which drives the flexion plates on both sides to move toward or away from each other through the rotation of the threaded adjustment shaft, so that the distance between the flexion plates is adapted to the size of the rubber seal to be tested, and then rotates the threaded limit shaft, so that the threaded limit shafts on the front and rear sides move toward each other and respectively clamp the left and right side walls of the rubber seal, thereby completing the limit fixation of the rubber seal to prevent the rubber seal from falling off during the test;

[0004] Although the technical solution provided by the utility model solves the problem that the seal may be detached from the test bench during use of the existing rubber seal testing device, after a long period of testing, the rubber seal may become disconnected due to reaching the upper limit of the number of tests. Since the rubber seal is in a stretched state when it becomes disconnected, the rubber seal will pop out quickly at the moment of disconnection, which may cause harm to nearby personnel, making it unsafe to use. Utility Model Content

[0005] The utility model aims to provide a rubber seal fatigue test bench with high safety to solve the problems raised in the above background technology.

[0008] Beneficial effects:

[0009] The utility model is provided with two clamping parts which can be moved closer to or farther away from each other. When the rubber seal needs to be tested, the rubber seal can be clamped by placing the rubber seal between the clamping parts. When the rubber seal breaks, it will not fly away, thus avoiding harm to nearby workers and making it safer to use.
