Description

Technical Field

[0001] The utility model relates to the technical field of sights, in particular to a sight impact test bench. Background Art

[0002] Rifles may be subject to various shocks and vibrations during use, such as accidental collisions during transportation, storage, or actual use. Therefore, shock testing can assess whether a riflescope can maintain normal functionality under these conditions, thereby ensuring its reliability in harsh environments. Shock testing simulates the impact scenarios a riflescope may encounter in actual use, helping to identify potential design flaws or material issues. These tests can optimize the design and improve material strength, thereby extending the service life of the riflescope.

[0003] In the prior art, when impact testing a scope, the test is mainly carried out through the vibration generated by intermittent impact. However, the vibration amplitude is generated at the impact position, causing the vibration amplitude to move left and right at the impact position, which can only produce a single vibration amplitude and cannot achieve the purpose of diversified vibration amplitude testing. Therefore, we propose a scope impact test bench to solve the above problem. Utility Model Content
