Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator vertical beams, in particular to a refrigerator vertical beam sealing structure. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. The box contains a compressor, an ice maker, a cabinet or box for freezing, and a storage box with a refrigeration device. For a large double-door refrigerator, a vertical beam is required in the middle of the double doors to seal the double doors. The traditional refrigerator vertical beams and double doors are sealed with sealing strips, and the sealing effect is poor. The sealing strips are easy to loosen after being squeezed for a long time, resulting in the refrigerator door not closing tightly, and the cold air inside leaks, increasing electricity consumption.

[0003] After searching, a refrigerator vertical beam sealing structure disclosed in the prior art (application number: CN202223293179.3) records in the text that "a placement slot is provided on one side of the refrigerator body, a refrigeration door panel and a freezer door panel are provided on one side of the refrigerator body, and a side sealing assembly is provided between the refrigerator body and the refrigeration door panel and the freezer door panel. Two convex mounting grooves are provided on one side of the refrigerator vertical beam, and convex sealing gaskets are installed on the inner walls of the two convex mounting grooves. A convex slot is provided on one side of the convex sealing gasket, and a connecting sealing rubber is installed on one side of the refrigeration door panel.

A double-layer sealing assembly is provided on one side of the refrigerator vertical beam."; The sealing structure of the refrigerator vertical beam is provided The arrangement can provide a good support and sealing effect for the refrigerated door panels on both sides during the closing process. After the refrigerated door panels are closed, the connecting sealing rubber will be driven to move, and the sealing end head at the front end of the connecting sealing rubber can be stuck in the convex groove. The sealing end head is elastic, and its end portion contacts and squeezes the inner wall of the convex groove. At this time, the sealing fitting surface on the rear side of the sealing end head can be connected with the convex groove, thereby ensuring the sealing of the refrigerated door panels after closing. However, the convex sealing gasket and the connecting sealing rubber of the sealing structure are prone to corresponding wear due to friction after long-term use, and corresponding structural deformation will also occur, which will then reduce the sealing effect between the convex sealing gasket and the connecting sealing rubber, thereby reducing the sealing stability of the vertical beam sealing structure.
