Description

Technical Field

[0001] The utility model relates to the technical field of impact testing, in particular to a portable adjustable impact testing rod. Background Art

[0002] Impact testing is a test method used to evaluate the performance and reliability of materials, products or structures when subjected to impact loads. In impact testing, an impact body (such as a steel ball or a pendulum) is usually used to impact the object being tested at a certain speed and energy, and then the response of the object being tested is observed and analyzed, such as whether cracks, deformation or damage occur. In this way, the load-bearing capacity, toughness and strength of the object being tested under impact loads can be understood.

[0003] The pendulum impact testers or drop hammer impact testers currently available on the market for impact testing are mainly configured with a host, a computer, a printer, a control program, a fixture and supporting tools, but most of them are used in laboratories, the equipment cost is relatively high and the weight is large. Currently, there are no impact testing machines that can be used on-site on the market, and there is a lack of portable and adjustable impact testing structures that can be applied to complex and changeable on-site environments. As a result, the impact testing structures can be applied in relatively limited scenarios, have poor portability and high production costs. Therefore, those skilled in the art provide a portable adjustable impact testing rod to solve the problems raised in the above background technology. Utility Model Content

After merging the supporting legs and storing the scale rod in the storage tube, the portability of the entire test rod can be increased, avoiding the problem of limited application scenarios of the impact test structure, poor portability and high production cost due to the lack of a portable and adjustable impact test structure that can be applied to complex and changeable field environments.
