Description

Technical Field

[0001] The utility model relates to the technical field of cold storage equipment, in particular to a high-speed cold storage door. Background Technique

[0002] Before the development of artificial refrigeration, humans already knew how to use natural ice and snow to maintain low temperatures in simple equipment, that is, to use natural cold sources. In China, natural ice has been used to preserve food for about 3,000 years. In the Book of Songs in the 7th century BC, there are verses about collecting, storing, and refrigerating food with natural ice. Even today, people still use natural cold sources such as ice, snow, and groundwater. Refrigeration devices cooled by natural ice or artificial ice can only reach limited low temperatures, with poor technical and hygienic conditions and difficulty in meeting various requirements. Modern refrigeration devices all use refrigerators to cool. In 1834, J. Perkins in the United States successfully trial-produced a continuously working refrigerator powered by manpower and using ether as the working fluid.

[0003] A patent with the publication number CN217357763U has proposed a high-speed cold storage door. The cold storage door is provided with a door frame, an upper slideway, a lower slideway, a moving door, a sealing device, a buffer pad, a suspension device, and a driving device. The suspension device includes an upper plate, a suspension magnet, a suspension coil, and a suspension housing. The driving device includes an upper driving magnet, a lower driving magnet, an electric rail, a driving rod, a lower fixing block, and a conductive support. The sealing device includes a sealing airbag, a ventilation pipe, and a two-way air pump. The utility model belongs to the technical field of cold storage equipment and specifically provides a cold storage door that is labor-saving to open and close and has a rapid door opening and closing speed.

[0004] Although the above cold storage door can be closed and sealed in time after being opened, it cannot well continuously preserve the cold air, has relatively poor use effects, is prone to cold air loss, and reduces the use of the cold storage door. To address the above problems, we have proposed an improved and upgraded high-speed cold storage door. Content of the Utility Model
