Description

Technical Field

[0001] The utility model relates to the field of metal material test research, in particular to a high-temperature durable sample connector. Background Art

[0002] The high-temperature tensile property of metal is one of the important indicators to measure the mechanical properties of materials, and the high-temperature endurance strength test is a material mechanical property test that tests the maximum stress that does not cause fracture within a specified duration when the material is subjected to a constant load at a certain temperature. The high-temperature endurance strength provides an important basis for the design and material selection of high-temperature components.

[0003] The existing high-temperature and durable specimen connectors, the connection between the stainless steel pull rod and the upper and lower joints are all in the form of threaded connection, that is, a threaded hole is made in the center of the upper and lower joints, and the stainless steel pull rod is directly tightened to achieve the connection. When connecting the specimen, the connection between the upper and lower joints will be very slippery, which is not convenient for connecting the stainless steel pull rod with the upper and lower joints. When connecting the upper joint to the testing machine, the connection between the lower joint and the connector body will cause looseness, which will lead to unstable connection between the specimen and the testing machine and inaccurate experimental data.

[0004] Therefore, it is necessary to provide a new high temperature durable sample connector to solve the above technical problems. Utility Model Content
