It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0018] Example 1: like Figures 1 to 2 As shown, this utility model discloses a portable pot-drop impact tester, comprising: The triangular top plate 1 has a central opening; Support column 2, consisting of three columns, is circumferentially mounted to the lower edge of the triangular top plate 1 by bolts; The directional sleeve 3 is bolted to the upper end of the triangular top plate 1 and is coaxial with the through hole; The guide post 4 is inserted through the through hole into the middle of the triangular top plate 1, and one end of it is provided with a threaded mounting hole, and the other end is provided with a threaded protrusion. The impact pot 5 is located below the triangular top plate 1 and includes a pot body 51 and a top cover 52 threadedly connected to the inner edge of the pot body 51. A counterweight cavity for filling counterweight filler is formed between the pot body 51 and the top cover 52. A threaded through hole is opened in the middle of the top cover 52. The diameter of the contact surface between the lower end of the pot body 51 and the surface of the microcrystalline glass is 120mm±10mm to simulate the situation of a wok falling in daily use. The lifting handle 6 is located above the triangular top plate 1, and its lower end is provided with a threaded protrusion 2; The lower end of the guide post 4 is threadedly connected to the threaded through hole of the top cover 52 through a threaded protrusion 1, and the upper end of the guide post 4 passes through the upper end of the directional sleeve 3 and is threadedly connected to the threaded protrusion 2 of the lifting handle 6 through a threaded mounting hole.

[0019] By adopting the above technical solutions, the tester adopts a modular design, which can be quickly disassembled and assembled. It has a small overall size, making it easy to transport, store and conduct on-site testing. The pot body and top cover of the impact cooker form a counterweight cavity, and the total impact weight can be adjusted by filling different weights of counterweight filler to adapt to the impact resistance test standards of different specifications of microcrystalline glass panels. The directional sleeve is coaxial with the through hole of the triangular top plate, and the guide post passes through the through hole and is threadedly connected to the impact pot and the lifting handle to form a precise vertical guide structure, ensuring that the impact pot moves in a straight line during its fall and that the impact position is accurate. Threaded connections and bolt fastening methods can be assembled and disassembled without complicated tools, reducing assembly difficulty; The lifting handle allows operators to quickly lift the impact pot, simplifying the testing process and improving testing efficiency; Three support columns are evenly distributed around the lower end of the triangular top plate, forming a stable triangular support structure. This can effectively disperse impact loads, prevent the equipment from shaking or tipping over during testing, and ensure operational safety and testing stability. Specifically, the core component of this impact tester is the impact pot. The pot body can be made of copper or aluminum, preferably aluminum. The lower outer edge of the pot body has a rounded transition. The rounded transition design can effectively prevent the lower edge of the pot body from scratching the microcrystalline surface during the lifting and falling process, while ensuring the uniformity of force when the pot body contacts the microcrystalline surface. The radius of the rounded corner is at least 5mm. The weight of the lifting handle is about 0.7kg, the unloaded weight of the impact pot is about 0.5kg, and the counterweight cavity is filled with sand or other granules. By adjusting the amount of granules, the total mass of the impact pot can be precisely 1.80kg±0.01kg. The shock pot can be lifted by pulling the handle and guide column, and its maximum lifting height can reach 180mm. The above-mentioned parameters, including the selection of pot material, fillet radius, contact diameter, total mass tolerance, and maximum lifting height, are all compatible with the technical requirements for impact testing in the product standard. This impact testing device can visualize the impact testing method specified in the product standard, greatly improving the convenience of impact testing operations and the accuracy of test results.

[0020] Example 2: This embodiment provides a portable pot-drop impact tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0021] Furthermore, the lifting handle 6 is spherical, the threaded protrusion 2 is integrally formed with the lifting handle 6, and the threaded protrusion 1 is integrally formed with the guide post 4.

[0022] By adopting the above technical solution, the spherical lifting handle fits the curvature of the hand, the force is more evenly distributed, the operator can easily lift the impact pot, reduce the operation intensity of long-term testing, and improve the user experience. The lifting handle and the threaded protrusion are integrally molded, reducing the number of detachable connecting parts and avoiding the risk of the handle loosening or falling off during use. This enhances the structural stability of the equipment and ensures the safety of the impact testing process.

[0023] The threaded protrusion is integrally formed with the guide post, resulting in high structural strength and effectively preventing breakage or loosening at the connection between the threaded protrusion and the guide post.

[0024] Example 3: This embodiment provides a portable pot-drop impact tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] Furthermore, a circular boss 53 is integrally formed on the upper center of the top cover 52, and a threaded through hole is opened on the upper center of the circular boss.

[0026] By adopting the above technical solution, the circular boss increases the wall thickness of the connection between the top cover and the guide column, improves the load-bearing capacity and impact resistance of the threaded connection, avoids deformation and breakage at the connection due to concentrated force when the impact pot falls, and extends the service life of the equipment.

[0027] Example 4: This embodiment provides a portable pot-drop impact tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0028] Furthermore, it also includes: The limiting ring 7 is located between the triangular top plate 1 and the impact pot 5, and is sleeved on the guide post 4; Among them, the limiting ring 7 is threaded with a fastening bolt on the radially outer side.

[0029] By adopting the above technical solution, adjusting the position of the limiting ring on the guide column and tightening the fastening bolts, the maximum lifting height of the impact pot can be precisely controlled, thereby accurately adjusting the impact drop distance and realizing the quantitative adjustment of different impact forces to meet the impact resistance test requirements of different microcrystalline glass panels.

[0030] Example 5: This embodiment provides a portable pot-drop impact tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] Furthermore, the directional sleeve 3 includes a disc base, a cylindrical outer liner integrally formed on the upper end of the disc base, and a cylindrical inner liner that passes through the disc base and is nested within the cylindrical outer liner; The disc base and the support column are both connected to the triangular top plate 1 by internal hex bolts, and two symmetrically arranged arc-shaped notches are opened at the upper end of the cylindrical outer liner.

[0032] By adopting the above technical solution, the inner and outer cylinders are nested to form a double guiding constraint. The cylindrical outer liner ensures structural stability with its integral molding rigidity. The cylindrical inner liner can be made of wear-resistant and low friction coefficient materials such as wear-resistant alloys, so that the guide column slides more smoothly with the inner wall of the liner during the lifting and falling process, effectively avoiding jamming caused by the material characteristics of a single cylinder. The cylindrical liner is a detachable and replaceable structure. When the guide post slides for a long time and the liner wears, it is not necessary to replace the entire directional sleeve. The arc-shaped notch facilitates the pushing of the inner liner out of the outer liner, making it easy to replace the inner liner; The disc base increases the contact area between the directional sleeve and the triangular top plate, dispersing the impact force during the test and preventing the directional sleeve from loosening or shifting due to excessive local force. The internal hex bolts provide reliable connections and strong vibration resistance, effectively preventing component loosening during impact testing and ensuring the stability of the testing process.

[0033] Example 6: This embodiment provides a portable pot-drop impact tester, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0034] Furthermore, the upper edge of the inner edge of the pot body 51 is provided with an internal thread, and the outer radial side of the top cover 52 is provided with an external thread that matches the internal thread.

[0035] By adopting the above technical solution, the pot body and the top cover are connected by internal and external threads. No additional clips or fasteners are required for disassembly and assembly. The top cover can be quickly opened to fill, replace or remove the counterweight filler in the counterweight cavity, realizing rapid adjustment of impact weight and improving the efficiency of test parameter adjustment. Secondly, the threaded connection effectively prevents the counterweight filler from falling out of the gap during the test, ensuring that the actual weight of the impactor is consistent with the set weight and avoiding deviations in test results due to filler loss.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
