Description

Technical Field

[0001] The utility model relates to the technical field of gasket testing, in particular to a gasket hardness testing device. Background Art

[0002] Gaskets are mechanical seals between two objects. There are several methods for testing their hardness, including Rockwell, Brinell, Leeb, and Shore. Different gasket materials may require different hardness testing methods, so it's important to choose the appropriate method based on your specific situation.

[0003] The existing patent application number is CN 202021978532.X, which discloses a gasket hardness testing device. By driving the tester body, the tester body performs interference detection on the gasket inside the slot, thereby obtaining data for analysis and calculation. By opening the slot and placement groove, the gasket is placed stably. However, the gasket is placed in the slot, and different slots need to be opened for gaskets of different sizes. Moreover, the device can only test the hardness of each gasket one by one, which has low detection efficiency and cannot meet the use requirements.
