[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] As a glass testing device, the glass bending strength testing equipment is designed to simulate the bending stress that glass may encounter in actual applications in order to accurately assess the bending strength of the glass. Using this testing equipment, we can conduct strength tests on various types of glass products, covering automotive windows, architectural glass, and glass sheets for various industrial applications. The testing equipment is usually installed using a base 1. A raised I-beam 101 and a pre-embedded hook 103 are set at the bottom of the base 1. When installing this device, a pre-embedded pit needs to be dug in the ground, the length and width of which are adapted to the base 1. Then, the raised I-beam 101 and the pre-embedded hook 103 are placed in the pre-embedded pit, and concrete is poured and allowed to solidify, thus obtaining a relatively stable base 1.

[0029] Example:

[0030] Reference Figures 1-4A glass bending strength testing machine includes a rectangular hollow frame 13 on the outer edge of a base 1. Protective structures are provided on all four sides of the frame 13 to prevent glass fragments from flying and injuring operators during testing. The hollow frame 13 enhances the overall structural strength of the device and provides necessary protection for the internal testing mechanism. Furthermore, openings are provided on the side walls of the frame 13 for placing glass into its cavity. A discharge channel 1 is formed between the long side of the base 1 and the frame 13. 4. The discharge channel 14 is located below the base 1. A glass collection box 15 is detachably connected inside the discharge channel 14. The glass collection box 15 is designed to facilitate the collection of glass fragments generated during the testing process, ensuring a clean and safe working environment. After the test is completed, the operator can easily remove the glass collection box 15 from the discharge channel 14 and clean out the fragments. A pressing mechanism is also provided at the top center of the frame 13, and a guide rail 10 is provided along the length of the base 1. Two sets of symmetrical movable seats 8 are slidably connected to the guide rail 10, allowing manual adjustment of the movable seats 8. The moving base 8 is positioned appropriately. Each set of moving bases 8 is equipped with support rollers 9. A pressing mechanism is positioned between two sets of support rollers 9, with its output end facing the plane of the support rollers 9. The moving base 8 can slide smoothly along the guide rail 10, thereby adjusting the distance between the two sets of support rollers 9 to accommodate testing requirements for glass samples of different sizes and specifications. The support rollers 9 are used to support the glass samples. During testing, the glass sample is placed on the support rollers 9 through the opening on the frame 13. The pressing mechanism applies pressure to simulate bending force, thereby evaluating the bending strength of the glass. The pressure is directed so that the output end of the pressing mechanism faces the plane of the support roller 9, ensuring that the applied pressure can be accurately applied to the glass sample, thereby improving the accuracy and reliability of the test. A guiding mechanism is also provided on the base 1, which is located above the guide rail 10. The top surface of the guiding mechanism has guide surfaces on both sides that are inclined towards the inlet of the discharge channel 14. The guide surfaces allow the glass sample to slide along a preset path before entering the test area, so that after the test, the glass sample can more easily slide from the base 1 to the discharge channel 14, which is convenient for subsequent collection and cleaning.

[0031] It should be explained that the above-mentioned pressing mechanism mainly includes a connecting seat 6, a pressure roller 7 is provided at the bottom of the connecting seat 6, and a telescopic component 3 is provided on the base 1. The telescopic component 3 can be an electric telescopic rod or a cylinder. A pressure sensor 4 is provided at the output end of the telescopic component 3. A mounting plate 5 is fixedly connected to the bottom of the pressure sensor 4. The connecting seat 6 is fixedly connected to the bottom of the mounting plate 5, and two sets of connecting seats 6 are symmetrically arranged. The long side axis of the connecting seat 6 is perpendicular to the long side axis of the base 1. By setting two sets of connecting seats 6, the pressure roller 7 can press on both sides of the glass centerline at the same time. During this process, the pressure sensor 4 intervenes, which can monitor and record the pressure value applied to the glass sample in real time, providing a reliable basis for subsequent data analysis and evaluation. The force applied by the pressure roller 7 is distributed to prevent stress concentration and improve the accuracy of glass strength testing.

[0032] In the above scheme, protective structures are set on all four sides of the frame 13 to block glass fragments and prevent them from flying during the test and injuring the operators. The design of the hollow frame 13 can enhance the overall structural strength of the device and provide necessary protection for the internal testing mechanism. By allowing the two sets of symmetrical moving seats 8 to slide smoothly along the guide rail 10, the distance between the two sets of support rollers 9 can be adjusted to meet the testing needs of glass samples of different sizes and specifications. The support rollers 9 are used to support the glass sample, and the two sets of pressure rollers 7 can press on both sides of the glass centerline. During this process, the pressure sensor 4 intervenes to monitor and record the pressure value applied to the glass sample in real time, providing a reliable basis for subsequent data analysis and evaluation. The force applied to the pressure rollers 7 is distributed to prevent stress concentration and improve the accuracy of glass strength testing.

[0033] The aforementioned protective structure includes a protective plate 16. Three sets of connecting rods are fixedly connected to the long side of the frame 13, forming a separate window between the connecting rods and the frame 13. The protective plate 16 is fixedly connected to the window. A discharge door 17 is hinged to the short side of the frame 13. The protective plate 16 is made of high-strength steel plate or high-strength tempered glass, which can effectively prevent glass fragments from flying. The discharge door 17 is designed to facilitate scraping or pushing the glass sample after the test. At the same time, the discharge door 17 is also equipped with a safety lock to prevent accidental opening during the test, further improving the safety of the operator. In addition, the stable connection between the connecting rods and the frame 13 ensures the stability and reliability of the protective structure, providing strong safety protection for the entire testing process.

[0034] To facilitate the protection of the guide rail 10, the aforementioned guiding mechanism includes a steel cover 11 slidably connected to the base 1. The top edges of the steel cover 11 intersect to form a pointed tip, which is positioned below the centerline of the long side of the pressure roller 7. The side edges of the steel cover 11 are coupled with the top surface to form a guiding surface. A partition is provided on the centerline of the base 1. Five sets of steel covers 11 are arranged from large to small between the partition and the movable seat 8. Each set of steel covers 11 is mutually adapted and positioned outside the guide rail 10. These steel covers 11 not only effectively protect the guide rail 10 from damage during testing, but also provide a pointed tip formed by the intersection of the top edges. The guide surface guides the glass sample to move along a predetermined path during the bending test. The partition further enhances the structural strength of the base 1. The steel covers 11 arranged from large to small can accommodate or extend the smaller steel covers 11 to form a complete guide surface. A limit cover 12 is slidably connected to the base 1. The limit cover 12 abuts against the outer wall of the moving seat 8 and is used to limit the moving seat 8 after it has moved. An inclined plate 102 is fixedly connected to the base 1. A support plate 2 is provided on the top of the inclined plate 102. The telescopic member 3 is fixedly connected to the support plate 2.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
