Description

Technical Field

[0001] The utility model belongs to the technical field of glass product testing, and in particular relates to a glass product strength testing instrument. Background Art

[0002] Strength testing of glass products can ensure that glass products meet the quality requirements of relevant standards and regulations, and ensure that the products will not be accidentally damaged or broken during use. Strength testing can evaluate the durability and stability of glass products when subjected to external pressure or impact, thereby improving the safety and reliability of products. Strength test results can provide a reference for product design and production, helping manufacturers optimize product structure and material selection to improve product strength and durability. In short, strength testing can help manufacturers and consumers understand the quality and performance characteristics of glass products, ensure product safety and reliability, and improve product competitiveness and market recognition.

[0003] During the strength test of glass products, impact testers are required to conduct impact resistance tests. Impact testers can simulate the behavior of glass products when they are subjected to external impact or blow, so as to evaluate the impact resistance of glass materials. This is crucial for judging the safety of glass products when subjected to unexpected impacts, such as safety glass doors and windows, car windshields, etc. Impact testers can help evaluate the fracture characteristics of glass materials when subjected to impact, including fragmentation mode, fracture morphology and damage area. This helps manufacturers understand the failure mechanism of glass products under different impact conditions, thereby improving product design and manufacturing processes. Quality control of glass products through impact testing machines can ensure that the strength and safety of the products meet the specified standards and requirements, and ensure the reliability and durability of the products. Therefore, impact testing machines play an important role in the strength testing process of glass products, helping manufacturers evaluate the performance and quality of their products. The problems with the above technology are: in the process of impact testing glass products through impact testing machines, it is necessary to place the glass products in the inner cavity of the test box and achieve the effect of impact testing the glass products through the cooperation of the impact device and the falling ball. However, because the top of the test box needs to be adapted and connected with the impact device and the falling ball, it is impossible to achieve the effect of protecting the glass products on all sides. After being impacted, the glass products will produce certain glass fragments, and the glass fragments cannot be protected during the splashing process, which will cause certain safety hazards to the users.
