[0023] See also Figure 1 A multi-layer co-extruded refrigerator air duct plate comprises an air duct cover plate 1 and a decorative plate 2. The decorative plate 2 is a multi-layer co-extruded plate. A positioning column 3 is installed on the front of the air duct cover plate 1. A positioning hole 4 that matches and corresponds to the positioning column 3 is opened on the back of the decorative plate 2. The decorative plate 2 is mounted on the front of the air duct cover plate 1 through the positioning hole 4.

[0024] Specifically, the decorative plate 2 is formed by double-layer co-extrusion by an extruder, and specifically includes an ABS layer 21 and a PMMA layer 22. The ABS layer 21 is installed on the front of the air duct cover plate 1, and the PMMA layer 22 is arranged on the front of the ABS layer 21.

[0025] The ABS layer 21 is used as the base layer to improve the overall strength and toughness, and the PMMA layer 22 is used as the surface layer for light transmission. The glass-like design replaces glass, which is beneficial to improving the aesthetics and reducing the production cost;

[0026] Furthermore, a protective layer 23 is provided on the front surface of the PMMA layer 22. The protective layer 23 is a PE or EPE transparent protective film, which can protect the front surface of the PMMA layer 22 and prevent scratches.

[0027] Specifically, a buckle 5 is installed at one end of the positioning column 3 away from the air duct cover plate 1, and the positioning column 3 is assembled with the positioning hole 4 through the buckle 5;

[0028] Furthermore, the positioning column 3 is cylindrical, and the number of the buckles 5 is multiple and arranged along the circumference of the outer wall of the positioning column 3. Through the arrangement of the multiple buckles 5, the positioning column 3 can be engaged with the decorative panel 2 at multiple points;

[0029] Furthermore, a small hole for accommodating the buckle 5 is provided on the outer wall of the positioning column 3. The buckle 5 is installed in the small hole through an elastic member and can be retracted inward and outward.

[0030] Furthermore, the end of the clip 5 located outside the small hole is hemispherical. When the decorative panel 2 is installed close to the air duct cover 1, the front end of the positioning column 3 will be inserted into the positioning hole 4. The hemispherical design of the outer end of the clip 5 allows the clip 5 to move into the small hole and compress the elastic member in the small hole. When the outer end of the clip 5 is completely moved into the small hole, the positioning column 3 continues to be inserted into the positioning hole 4. When the positioning column 3 is completely plugged and assembled with the positioning hole 4, the clip 5 moves to the relative position of the limit groove. The outer end of the clip 5 extends outward under the elastic action of the elastic member and is engaged with the limit groove, thereby completing the installation of the decorative panel 2. When disassembling, the decorative panel 2 only needs to be pushed outward with force to disengage the positioning column 3 from the positioning hole 4.

[0031] In summary, the multi-layer co-extruded refrigerator air duct plate proposed in the utility model forms a decorative plate 2 through double-layer co-extrusion of an ABS layer 21 and a PMMA layer 22. The high strength, high toughness and high corrosion resistance of the ABS layer 21 can be used to improve the overall strength and resistance of the decorative plate 2. Combined with the high transparency and easy processing characteristics of the PMMA layer 22, it is convenient for subsequent processing and can also play the role of imitating glass and improving the aesthetics. The positioning hole 4 on the back of the decorative plate 2 is clamped with the positioning column 3 on the front of the air duct cover plate 1 to achieve quick assembly of the decorative plate 2. Compared with gluing, the installation is more secure and not easy to fall off. In addition, the decorative plate 2 is lighter in weight. Compared with metal or glass materials, it can reduce production costs and is beneficial to the production efficiency of the enterprise.
