DETAILED DESCRIPTION

[0033] The specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0034] This embodiment provides a glass door, such as Figures 1-8 As shown, it includes a glass component 1, a door frame assembly 2 and an outer edging structure 3, the outer edging structure 3 is installed outside the door frame assembly 2, the outer edging structure 3 includes an outer plastic layer 31 and an inner plastic layer 32, the outer plastic layer 31 and the inner plastic layer 32 are made of different types of plastics, and the outer edging structure 3 is fixedly connected to the door frame assembly 2 through a fixing structure on the inner plastic layer 32.

[0035] The outer edging structure 3 includes two plastic layers, an inner layer and an outer layer, each made of different types of plastic. These two plastic materials provide a more flexible selection of plastics, allowing the outer edging structure 3 to meet decorative requirements at a lower cost. For example, when selecting the outer plastic layer 31, one can fully consider its weather resistance, wear resistance, aging resistance, and color, while the inner plastic layer 32 can fully consider its cost, thereby fully achieving a long-lasting decorative effect of the outer edging structure 3 at a lower cost. The inner plastic layer 32 can be made of a material that easily scratches, which can reduce the processing accuracy requirements of the inner plastic layer 32, making it easier for the fixed structure to adapt to the door frame assembly 2. It also helps to reduce the assembly gap between the inner plastic layer and the door frame assembly 2, thereby improving assembly stability. The outer plastic layer 31 can achieve a rich color selection at a lower cost, avoid the painting process, and reduce environmental pollution during product production.

[0036] In this embodiment, the outer plastic layer 31 is ASA plastic, and the inner plastic layer 32 is PVC plastic. The outer plastic layer 31 and the inner plastic layer 32 are fixed together by co-extrusion. The production cost of ASA plastic is relatively high, which may increase the cost of the final product. ASA plastic is a ternary polymer composed of acrylonitrile (acrylonitile), styrene (styrene), and acrylic rubber (acrylate), and is an impact-modified resin. ASA plastic not only resists degradation, aging, and fading caused by ultraviolet radiation, possessing excellent UV resistance, but also provides strong protection against decomposition or discoloration caused by high temperatures during atmospheric oxidation processing, thereby greatly improving the material's aging and weather resistance. Furthermore, ASA plastic reduces the processing costs of secondary processes such as painting and electroplating, making the product cost-effective and environmentally friendly. PVC plastic, on the other hand, is a widely used plastic material with relatively low production costs. Therefore, by co-extruding PVC and ASA plastics, the overall material cost can be reduced to a certain extent. PVC plastic has excellent plasticity and can be formed into various shapes through methods such as thermal processing and injection molding, making it easy to process into fixed structures.

[0037] The outer edge covering structure of the embodiment is double-layer plastic. In other alternative embodiments, the outer edge covering structure can be three-layer or more than three-layer plastic. In other alternative embodiments, the outer plastic layer 31 can also be PMMA plastic (polymethyl methacrylate).

[0038] As shown in Figure 4 , 6 , the fixing structure includes a first bending part 321 at the rear end edge of the inner plastic layer 32, the first bending part 321 has a first clamping part 323 extending inwardly, and the outer plastic layer 31 covers the outer side of the first bending part 321. The outer plastic layer 31 extends to the outer surface of the first clamping part 323.

[0039] In other alternative embodiments, the outer plastic layer 31 can also partially cover the outer surface of the first clamping part 323.

[0040] In other alternative embodiments, the end of the first bending part 321 has a first rounded corner, the outer plastic layer 31 extends to the first rounded corner, and the length of the outer plastic layer 31 extending to the inner side of the first bending part 321 at the position of the first rounded corner is less than or equal to the thickness of the first bending part 321. The outer plastic layer 31 extends to the first rounded corner, and after the assembly of the outer edge covering structure 3, the outer plastic layer 31 can prevent the inner plastic layer 32 from being exposed while reducing the material of the outer plastic layer 31.

[0041] As shown in Figure 7 , the front end edge of the inner plastic layer 32 has a second bending part 322, the end of the second bending part 322 is a tapered end part 324 with gradually decreasing thickness, and the outer plastic layer 31 covers the outer side of the second bending part 322 and the outer side of the tapered end part 324. The outer side of the tapered end part 324 is arc-shaped, and the inner side of the tapered end part 324 is planar. The second bending part 322 has a larger planar surface on the inner side to press the glass piece 1, and the sharper end part can reduce or avoid the exposure of the inner plastic layer 32 on the inner side. In other alternative embodiments, the outer plastic layer 31 can also partially cover the outer side of the tapered end part 324.

[0042] As shown in Figure 7 , the thickness of the outer plastic layer 31 is less than the thickness of the inner plastic layer 32. This can reduce the cost and facilitate the plasticity of the inner plastic layer 32, making it easier to form rounded corners and bends in the outer edge covering structure 3. When the thickness of the outer edge covering structure 3 is 1.5 mm, the thickness of the outer plastic layer 31 can be 0.3-0.5 mm, preferably 0.4 mm.

[0043] As shown in Figure 2As shown, the outer edge structure 3 includes a U-shaped edge 33 wrapped around the two sides and top of the door frame assembly 2, and a bottom edge 34 wrapped around the bottom of the door frame assembly 2, both of which are formed by co-extrusion of an outer plastic layer 31 and an inner plastic layer 32. The two corners of the U-shaped edge 33 are rounded to avoid the appearance of a connecting gap on the three edges, thereby improving the aesthetic appearance.

[0044] In other alternative embodiments, the outer edge structure 3 includes two L-shaped edges wrapped around the two sides and top of the door frame assembly 2. The two L-shaped edges form a U-shaped edge 33.

The larger front glass 11 can increase the coverage of the glass piece 1, the elastic rib 213 can improve the sealing of the glass piece 1 and the door frame assembly 2, and play a buffering role during installation of the glass piece 1. The elastic rib 213 integrally formed on the second support platform 212 is beneficial to improving the assembly efficiency. The glass piece 1 of the present embodiment is a hollow glass assembly, and in other alternative embodiments, the glass piece 1 can also be a single-layer glass.

[0047] Further, the outer ring of the spacer assembly 12 is sealed by glue to form a sealed cavity between the front glass 11 and the back glass 13, and the sealed cavity is provided with a LOGO lamp disc assembly, which is placed on the back glass 13 and fixed.

[0048] The spacer assembly 12 includes multiple sections of hollow spacers, the hollow spacers are filled with molecular sieves, and the multiple sections of hollow spacers are spliced by plastic pins to form the spacer assembly 12. In other alternative embodiments, the spacer assembly 12 is connected as a whole by being pasted on the glass by a super spacer warm edge strip.
