Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator equipment, in particular to a plastic extrusion splicing structure of a refrigerator door handle. Background Art

[0002] With the continuous improvement of living standards, people's pursuit of beauty is getting higher and higher. Refrigerators, as a necessity for modern families, are no exception. In recent years, the competition in the refrigerator industry has become increasingly fierce. How to design a refrigerator door handle that is both practical, beautiful and affordable has become a difficult point in the door design of the refrigerator industry. Most of the previous refrigerators had integral plastic door handles with a single appearance that did not meet the aesthetic needs of modern people.

[0003] The door handles of existing refrigerators, especially those with a capacity of more than 300 liters, have begun to change to aluminum alloy door handles or additional injection molded parts or decorative strips on the original handles. The overall aluminum alloy handle has a strong structure but is very expensive and has a single form; aluminum alloy is installed on the door cover as a door handle and decoration. Because the flatness of plastic parts is difficult to control, gaps are easily generated between the door cover and the aluminum alloy handle, affecting the appearance, and the cost is relatively high. Now many companies use co-extruded decorative strips to buckle on door handles as decoration, but because the decorative surface is too small to be printed or marked, the effect is not very good. If the injection molding is done by in-mold injection molding plus co-extruded buckle strips, it is difficult to achieve consistent colors due to different parts processing methods, and the cost is relatively high.

[0012] As a preferred solution of the plastic extrusion splicing structure of the refrigerator door handle described in the utility model, the number of the second screws is six, and the second screws are made of stainless steel.

[0013] Beneficial effects of the utility model:

[0014] 1. The door cover, decorative panel and decorative strip are all made of plastic co-extrusion, and then they can be spliced ​​for various screen printing or painting. The decorative splicing parts adopt the co-extrusion process, which is convenient to control the appearance color, good stability, mature plastic co-extrusion process, and low cost compared with other methods. The setting of the seam filling structure groove and the seam filling structure rib solves the gap problem between the door cover and the door handle caused by the existing integral decorative strip as a door handle. The cavity structure on the back of the decorative panel solves the warping deformation problem caused by injection molding or flat plate extrusion.

[0015] 2.
