Technical Field

[0002] Tinplate, also known as tin-plated iron, is the common name for electroplated tin thin steel sheet, which refers to cold-rolled low-carbon thin steel sheet or strip plated with commercial pure tin on both sides. Tin mainly prevents corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one material. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility, and is therefore widely used in food packaging.

[0003] After searching, Chinese patent publication (announcement) No. CN207274202U discloses a tinplate with a pattern mark. This product includes a tinplate substrate and a coating. There is a concave-convex pattern or mark on the tinplate substrate by roller pressing between the tinplate substrate and the coating. This product is not only environmentally friendly but also low-cost and anti-counterfeiting through roller pressing; and the concave-convex pattern or mark is located between the tinplate substrate and the coating, so it will not damage the substrate and the coating, and the coating treatment is performed on the roller-pressed pattern or mark. The pattern or mark can be clear or hidden, but the pattern or mark is long-lasting and anti-counterfeiting throughout the process. The pattern or mark is clear, smooth and bright, so it is more beautiful, and the overall appearance is high-end and restrained, thereby improving the competitiveness of the product, and can meet customers' design requirements for patterns or marks, thereby meeting customers' ultimate anti-counterfeiting needs and higher quality requirements that are difficult to copy.

[0004] Although the tinplate of the above patent can add patterns, the tinplate does not have strong corrosion resistance, its surface is easily damaged, and the corroded tinplate cannot be effectively recycled. Therefore, it is necessary to design a brazable and corrosion-resistant tinplate to solve the above problems. Utility Model Content

[0027] During specific use, due to the settings of the weather-resistant layer 4, the corrosion-resistant layer 5, the waterproof layer 6, the tin plating layer 7 and the wear-resistant layer 8, both the housing 1 and the top cover 2 are made of tinplate materials and are formed by multi-layer structure composite.

The pattern layer 9 is arranged on the outermost layer of the housing 1, which can enhance the aesthetics and protection of the surface of the housing 1. The wear-resistant layer 8 is arranged in two layers, corresponding to the inside and outside of the housing 1 respectively, increasing the wear resistance of the outside and inside of the housing 1 and the top cover 2, reducing wear during long-term use and avoiding damage and leakage of the internal tin plating layer 7. The surface of the tin plating layer 7 has a high thickness of the free tin layer, has good soldering performance, and at the same time has high soldering and strong corrosion resistance, increasing the ductility of the tinplate. The waterproof layer 6 wraps the corrosion-resistant layer 5, the weather-resistant layer 4 and the reinforcing layer 3, avoiding internal rusting, improving the service performance and making it more durable. The corrosion-resistant layer 5 improves the corrosion resistance of the tinplate, prevents the tinplate from being corroded and damaged due to long-term use, and improves the service life of the tinplate. The weather-resistant layer 4 reduces the influence of the external environment on the tinplate, effectively improving the stability and toughness of the material and meeting the use requirements.

[0028] In this embodiment, the reinforcing layer 3 includes a substrate 10, and a compression-resistant plate 11 is fixedly connected to the lower surface of the substrate 10.

[0029] During specific use, due to the setting of the compression-resistant plate 11, the compression-resistant plate 11 is arranged between the substrate 10 and the reinforcing plate 12, which can improve the overall compression resistance of the tinplate, enable it to bear greater pressure, make the force more uniform, and make the structure more stable.

[0030] In this embodiment, a reinforcing plate 12 is fixedly connected to the lower surface of the compression-resistant plate 11.

[0031] During specific use, due to the setting of the reinforcing plate 12, the reinforcing plate 12 is composed of a combination of multiple groups of cross-fixed plates, which can enhance the strength of the tinplate and has high extensibility.

[0032] In this embodiment, a threaded groove 13 is opened at the top of the outer surface of the housing 1, and an external thread 14 is fixedly connected to the inner side surface of the top cover 2.

[0033] During specific use, through the arrangement of the thread groove 13 and the external thread 14, the top cover 2 is threadedly connected to the inside of the thread groove 13 on the outer surface of the shell 1 through the external thread 14.

[0036] In this embodiment, a sealing gasket 17 is fixedly connected to the middle portion of the inner top wall of the top cover 2 .

[0037] During specific use, the sealing gasket 17 is provided to increase the sealing performance of the connection between the top cover 2 and the inner side of the shell 1 , thereby reducing the influence of the external environment on the interior of the shell 1 .

[0038] In this embodiment, a reinforcing rib 18 is fixedly connected to the middle portion of the lower surface of the housing 1 .

[0039] During specific use, by setting the reinforcing ribs 18, a plurality of reinforcing ribs 18 are evenly fixed in the middle of the lower surface of the shell 1 in the form of a circular array, so that the structural strength of the bottom of the shell 1 can be strengthened.

[0040] In this embodiment, a rubber pad 19 is fixedly connected to the lower surface of the reinforcing rib 18 .

[0041] During specific use, by setting the rubber pad 19, the rubber pad 19 can enhance the friction between the shell 1 and the desktop when it is placed, making the placement more stable, and at the same time can reduce the wear of the bottom during use, further enhancing the protectiveness.

[0042] Working principle: During use, the top cover 2 is threadedly connected to the inside of the thread groove 13 on the outer surface of the housing 1 through an external thread 14. The threaded connection facilitates multiple uses. The gasket 17 enhances the sealing performance at the connection between the top cover 2 and the inner side surface of the housing 1. The anti-slip sleeve 15 and multiple anti-slip particles 16 are used in cooperation to prevent the user's hand from slipping and causing the housing 1 to fall. Multiple reinforcing ribs 18 strengthen the structural strength of the bottom of the housing 1. The rubber pad 19 makes the housing 1 more stable when placed. The compression plate 11 is arranged between the base plate 10 and the reinforcing plate 12 to improve the overall compressive performance of the tinplate, which has a relatively high extensibility. The waterproof layer 6 prevents rust from occurring inside. The anti-corrosion layer 5 improves the corrosion resistance of the tinplate. The weather-resistant layer 4 reduces the influence of the external environment on the tinplate. The tin plating layer 7 has good soldering performance and at the same time has high soldering and strong anti-corrosion performance. The wear-resistant layer 8 increases the wear resistance of the outer and inner sides of the housing 1 and the top cover 2, reducing wear during long-term use. The pattern layer 9 is arranged on the outermost layer of the housing 1, which can enhance the aesthetics and protection of the surface of the housing 1.
