Description

Technical Field

[0002] In the prior art, the pendulum impact tester is an important device for testing the impact resistance of materials. Since the high-speed movement and impact of the pendulum during the test may cause material fragments to splash, the safety of this device during use is extremely important. Usually, in order to protect the operator and the surrounding environment, the pendulum impact tester is equipped with a protective device, mainly including a protective plate to block possible fragments and reduce noise.

[0003] However, in the existing technology, these protective devices, especially the side and front protective plates, have some limitations. Although these protective plates can provide basic protection in design, they are insufficient in flexibility and adjustment, making it inconvenient to adjust the position and angle of the protective plates when testing samples of different sizes or shapes. Due to the fixedness and difficulty in adjustment of the protective plates, operators need to spend extra time to adapt to the position of the protective plates during the test preparation stage, or when performing specific test configurations, all risk areas may not be fully covered, thus affecting the convenience and safety of use.
