[0026] Rubber hardness, which is equivalent to the diaphragm hardness mentioned above, refers to the indentation depth formed by pressing a needle of specified shape into the material being tested under specified conditions, and then converting the indentation depth into a hardness value. This value reflects the ability of rubber material to resist external force pressing into its surface, and is an important indicator of the degree of rubber hardness. Rubber hardness measurement is one of the important means to evaluate the performance of rubber materials. Rubber hardness testing has a wide range of applications in the production, quality control and research and development process of rubber products. By testing the hardness of rubber, its physical properties and service life can be evaluated, providing important reference for product design and production. In addition, rubber hardness testing can also be used to compare the performance differences of different rubber materials, providing scientific basis for material selection and application. The main rubber hardness testing methods currently include Shore hardness testing and International Rubber Hardness (IRHD) testing. Among them, Shore hardness testing is to press a steel needle with a certain shape vertically into the surface of the test sample under the action of test force. When the pressure foot surface completely matches the test sample surface, the tip of the pressure needle has a certain length of protrusion relative to the pressure foot plane (i.e. the depth of the pressure needle into the measured object), and the length value is used to represent the size of Shore hardness.

[0027] The accompanying drawings are referred to in Figs. 1-3 The embodiments are provided to further illustrate the portable diaphragm spare part hardness measuring device provided in the present application.
