Embodiment Construction

[0016] see figure 1 and Figure 1a , the structural form of the soft-hard co-extruded refrigerator inner door seal in this embodiment is: the hard part in the soft-hard co-extruded inner door seal is arranged on one side of the fixed body 2 and is in an "L" shape with the fixed body 2 Form the overhanging side 3 connected with the elastic body 4, the elastic body 4 is connected to the overhanging side 3 and extends toward the side of the tank 5, and the front arc edge is against the inner side of the tank 5, forming on the refrigerator door 1 The seal between the inner side of the inner side and the inner side of the tank bladder 5.

[0017] In a specific implementation, the fixed body 5 is a flat piece or a fastener fixedly arranged on the refrigerator door liner 1, and the specific shape is set according to the fixing structure at the corresponding position of the refrigerator door liner.

[0018] The present invention can be suitable for other occasions where the elastic...

Abstract

The invention discloses a soft-hard co-extrusion internal refrigerator door seal. The soft-hard co-extrusion internal refrigerator door seal is characterized in that the arranged hard part in the soft-hard co-extrusion internal door seal and a fixed body form an L shape on one side edge of the fixed body so as to form an overhanging edge connected with an elastic body, the elastic body is connected with the overhanging edge and extends to one side of a box container, and the front-section arc edge of the elastic body leans against the inner side of the box container, so that the seal between the inner side of a refrigerator door container and the inner side of the box container can be formed. According to the soft-hard co-extrusion internal refrigerator door seal, the length of the elastic body is shortened, the elastic strength of the elastic body is improved obviously, and the service life of the internal door seal is prolonged obviously.

Description

technical field [0001] The invention relates to a refrigerator inner door seal. Background technique [0002] The inner door seal of the refrigerator is another sealing measure between the side of the refrigerator door liner and the inner side of the box liner. The inner door seal of the refrigerator in the prior art is as follows: figure 2 and Figure 2a As shown, it is a soft and hard co-extruded component, and its hard side strip 11 is a flat plate-shaped fixing part for fixing on the side of the refrigerator door liner 1, and its soft side strip 12 is an elastic body. The elastic body is connected with one side of the hard side strip on one side, and the other side is a cantilever extending to the inside of the box liner 5, and leans against the inside of the box liner with the arc-shaped edge of the cantilever front end, forming a The seal between the inside of the liner and the inside of the tank. In this structural form, due to the long suspension of the soft side ...
