Description

Technical Field

[0001] This invention belongs to the field of cylindrical cabinet technology, and particularly relates to a cylindrical cabinet and its installation method. Background Technology

[0002] A cylindrical freezer is a device used for refrigerating or freezing items. Traditional freezers are mostly square, with rectangular cross-sections for their components, making the correspondence between components relatively easy to determine. However, cylindrical freezers are cylindrical or conical, with circular cross-sections for their components. Relying solely on shape correspondence makes precise positioning of components impossible, undoubtedly increasing the manufacturing difficulty, reducing production efficiency, and lowering assembly quality. While current technologies often use protrusions and grooves between components requiring high connection precision to facilitate assembly, this improves the overall structure and, given the large number of components, further complicates assembly efficiency. Therefore, current cylindrical freezer technology suffers from low production efficiency, and the assembly quality of its components needs improvement. Summary of the Invention
