Technical Field

[0001] This utility model belongs to the field of refrigerated vehicle technology, specifically relating to a sealing mechanism for refrigerated vehicles. Background Technology

[0002] With the development of the cold chain logistics industry, customers have higher and higher requirements for delivery speed. Therefore, they also have higher requirements for the ease of operation of refrigerated vehicles. Sliding doors are becoming increasingly popular with customers because they are easy to use and facilitate forklift operations, which can effectively improve loading and unloading efficiency.

[0003] However, existing refrigerated trucks often lack a secondary sealing structure, which can easily reduce the sealing between the side door and the side door panel of the refrigerated truck. This can lead to a decrease in the sealing and heat preservation performance of the refrigerated truck, causing inconvenience during use. Therefore, there is an urgent need for a sealing mechanism for refrigerated trucks to solve the above problems. Utility Model Content
