TECHNICAL FIELD
[0001] The utility model relates to cold storage door technical field, concretely relates to a cold storage door with high -efficient sealing structure. BACKGROUND
[0002] The cold storage door is a door specially designed for refrigeration and freezing environment, mainly used in cold storage, refrigerated vehicle, refrigerated room, refrigerator and other places to ensure the stability of internal temperature and efficient use of energy. The design of the cold storage door not only needs to consider the sealing property, low-temperature resistance, but also needs to ensure the safety, convenience and durability during use. In large food cold storage, the cold storage door is used to ensure the storage temperature of food and prolong the shelf life of food. Especially in the frozen food storage area, the performance of the cold storage door is particularly critical. Some medicines and vaccines need to be stored in a low-temperature environment. The cold storage door can ensure the stability of temperature control and is a key component of medical cold chain transportation and storage. In refrigerated vehicles and cold chain logistics warehouses, the cold storage door ensures the refrigeration and freezing conditions of goods and ensures the freshness of goods during transportation. In some industrial production, specific raw materials or finished products need to be stored in cold storage. The heat insulation performance and sealing performance of the cold storage door are very important.
[0003] When storing food and medicine, the sealing effect of the general cold storage door is poor. After being opened and closed for many times, a large gap is easily formed between the cold storage door and the door frame, causing the cold air in the cold storage to overflow. It is difficult for the cold storage to effectively maintain a stable and appropriate low-temperature state. The shelf life of the stored food and medicine is easily shortened due to temperature fluctuations, resulting in food spoilage or loss of drug efficacy. At the same time, the overflow of cold air also easily increases energy consumption, causing resource waste. When the general cold storage door is used, frost phenomenon is easily formed between the cold storage door and the door frame, making it difficult to open the cold storage door. To solve the above problems, a cold storage door with high sealing efficiency is proposed. UTILITY MODEL CONTENTS
