Description

Technical Field

[0001] This utility model relates to the field of door and window manufacturing technology, specifically to a strength testing device for aluminum alloy doors and windows. Background Technology

[0002] With the booming development of the construction industry, aluminum alloy doors and windows have been widely used in various construction projects due to their numerous advantages, such as light weight, high strength, aesthetic appeal, durability, and excellent sealing performance. The strength performance of aluminum alloy doors and windows directly affects their safety and reliability in actual use; therefore, accurate and standardized strength testing of aluminum alloy doors and windows is particularly important.

[0003] In the existing field of aluminum alloy door and window strength testing technology, numerous testing devices are dedicated to accurately measuring key strength indicators such as the maximum external force and deformation that doors and windows can withstand, in order to accurately assess whether their quality meets relevant standards and actual usage requirements. Common testing devices typically consist of a loading system, fixing fixtures, and a corresponding data acquisition system. They complete the testing work by applying different forms of external force (such as tension and compression) to the doors and windows and recording the changes in various parameters of the doors and windows during the stress process.

[0004] However, most existing testing devices have a significant drawback: during strength testing, a large external force is applied to aluminum alloy doors and windows, especially when testing large or high-strength ones. This can cause the doors and windows to crack under the intense pressure or tension, resulting in a large number of flying fragments. These fragments often have high speed and sharp edges, posing a serious risk of personal injury to operators at the testing site. They can also damage other equipment or property, making them inconvenient to use and causing considerable inconvenience. Therefore, based on the above findings, a strength testing device for aluminum alloy doors and windows is proposed to address this issue. Utility Model Content
