Description

Technical Field

[0001] The utility model relates to the field of bracket installation structures, in particular to a bracket mechanism of a low-voltage switch cabinet. Background Art

[0002] Low-voltage switchgear is used for power transmission, distribution and energy conversion. When installing switch devices, brackets are required. Traditional brackets have a simple structure, consisting of a single metal bracket and a mounting plate mounted on the metal bracket, which is fixed inside the low-voltage switchgear using nuts. The metal bracket is fixed in position inside the low-voltage switchgear and cannot be adjusted. It is easy for some switch devices to be large, resulting in the occupation of adjacent metal bracket installation areas. If you want to adjust them, you need to remove the metal bracket, which is troublesome and inconvenient. At the same time, in order to ensure the stability of the fixation, traditional metal brackets and mounting plates are generally installed with threaded fastening. However, since many switch devices are generally installed inside the low-voltage switchgear, a large number of mounting plates are required. The threaded fastening method is not convenient for installation and wastes time. Utility Model Content
