Description

Technical Field

[0001] The utility model relates to a corner turning mechanism of a metal cabinet door, which is a cabinet door corner turning mechanism. Background Art

[0002] The right-angle turning mechanism of the door frame in the existing metal cabinet door is generally an L-shaped mechanism, which occupies a large space and has high requirements for cabinet space. Among them, some existing energy storage cabinets are heavy in weight, which can easily cause deformation of the door panels and cabinets during the manufacturing and hoisting process, resulting in waterproof failure. Therefore, some similar products use the method of adding locking points in the horizontal position of the door panel to improve its protection. At the same time, the existing L-shaped right-angle turning mechanism has fewer parts and occupies a lot of space, so this structure is generally rarely used. There are some multi-locking point cabinet door devices or mechanisms, such as the authorization announcement number CN219993429U disclosed in the Chinese patent literature, the authorization announcement date 2023.11.10, and the utility model name "connecting rod transmission mechanism linkage module"; another example is the authorization announcement number CN2448899Y disclosed in the Chinese patent literature, the authorization announcement date 2001.09.19, and the utility model name "a multi-locking point device installed on the door"; but the above products and similar products are difficult to use in the hoisting process of the energy storage cabinet, where the cabinet door corner mechanism has fewer parts, occupies a lot of space, and is difficult to lock with multiple lock points.
