Description

Technical Field

[0001] The utility model relates to the field of Shore hardness testers, in particular to a Shore hardness tester bracket. Background Art

[0002] Shore durometers are widely used to measure the hardness of rubber and plastics. In shipbuilding, Shore durometers are often used to measure the hardness of non-metallic materials such as rubber and plastics. The Shore durometer's operating principle is as follows: An indenter is pressed vertically into the specimen surface under the action of a test force. When the indenter foot and the specimen surface are in perfect contact, the indenter tip protrudes a certain distance relative to the indenter foot plane. This protrusion indicates the Shore hardness.

[0003] Currently, when using a Shore hardness tester, the indenter is directly pressed into the sample surface by holding the Shore hardness tester. However, the indenter needs to be pressed vertically into the sample surface to ensure the accuracy of the test data. When holding the Shore hardness tester, the indenter and the sample surface are easily deviated, affecting the accuracy of the test data. Utility Model Content

[0004] The utility model aims to provide a Shore hardness tester bracket to solve the problem that when the Shore hardness tester is directly held for testing, the indenter and the sample surface are easily deflected, thereby affecting the accuracy of the test data.

[0010] Furthermore, a second slide rail is installed on the bottom surface of the fixed plate, and a second slider matching the second slide rail is installed on the top surface of the movable plate.
