Multielement material co-extrusion refrigerator door seal

Abstract

The invention discloses a multielement material co-extrusion refrigerator door seal which is characterized by comprising a major structure, a cross beam, a fastener, an inner-side small wing edge anda step air bag. The major structure is located on the upper side of the cross beam; the fastener is located on the lower side of the cross beam; the inner-side small wing edge is located on the rightside of the cross beam; the step air bag is located on the right side of the major structure; the major structure, the cross beam, the fastener, the inner-side small wing edge and the step air bag areconnected into a whole; and the major structure is provided with a compensation air bag, a connecting air bag, a magnetic stripe hole cavity and an outer-side small wing edge. According to the multielement material co-extrusion refrigerator door seal provided by the invention, the hardness of various parts of the door seal can be different by adopting multielement material co-extrusion accordingto different parts, contacting a refrigerator, of the door seal, so that the door seal is good in overall stability and resistant to rubbing and pulling, various parts, contacting the refrigerator, ofthe door seal can be tightly laminated with the refrigerator, and the overall sealing performance of the refrigerator is ensured.

Description

technical field [0001] The invention relates to the field of door seal structures, in particular to a multi-component material co-extruded refrigerator door seal. Background technique [0002] Refrigerators are very common electrical appliances in life. The interior of the refrigerator can maintain a constant low temperature, so that the food or other items stored in the refrigerator can be kept at a constant low temperature to avoid deterioration and corruption. The basic requirement for the use of refrigerators is thermal insulation performance, and the door seal is an important part to ensure the thermal insulation performance of refrigerators. The refrigerator door seal is in contact with the refrigerator door and the refrigerator box at the same time during use. The inner side of the refrigerator door seal is in the low-temperature environment inside the refrigerator for a long time, and the outer side of the refrigerator door seal is in the normal room temperature outs...

AI Technical Summary

Problems solved by technology

In the actual production and use of the refrigerator, when the door seal with a hardness within the range of 70±5A is located on the refrigerator door, the rigidity of the door seal is too small, which makes the door seal less stable, and it is not resistant to rubbing and pulling when the refrigerator door is opened. When the refrigerator door is closed, gaps and twists are easy to appear; when the door seal with a hardness within the range of 70±5A is located inside the refrigerator, the door seal is too rigid and does not have low-temperature flexibility, so that the door seal fits well with the refrigerator body Low, poor sealing, resulting in the leakage of low temperature inside the refrigerator, loss of insulation performance of the refrigerator
