Description

Technical Field

[0001] The utility model relates to the technical field of a microcomputer-controlled electronic ring stiffness testing machine, and more specifically, to a microcomputer-controlled electronic ring stiffness testing machine. Background Art

[0002] In the prior art, microcomputer-controlled electronic ring stiffness testers are widely used to measure the ring stiffness, i.e., the ability to resist deformation, of pipes made of various materials. However, existing testers face certain challenges when faced with test pipes of different models and diameters. First, because the diameters of test pipes can vary greatly, existing test equipment often has difficulty effectively adapting to these different sizes. This lack of dimensional adaptability limits the versatility and flexibility of the tester, resulting in the inability to perform ring stiffness tests on certain pipes, or requiring additional components and adjustments to test pipes of specific diameters.

[0003] In addition, the problem of fixing the lateral plates is also a technical difficulty. During the test, the lateral plates are used to fix or stabilize the experimental tubes to ensure the accuracy of the test. However, in the prior art, the fixing mechanisms of these lateral plates are often not flexible or easy to use, making the adjustment and fixing of the lateral plates complicated and time-consuming. Especially when replacing experimental tubes of different diameters, adjusting the lateral plates to adapt to the new tube diameter size often requires the use of tools and more manual operations, which not only increases the complexity of the operation, but may also affect the efficiency and process of the entire test.
