Description

Technical Field

[0001] The utility model relates to the technical field of bolt-type quick-release brackets for switch cabinets, in particular to a novel bolt-type quick-release bracket for low-voltage switch cabinets. Background Art

[0002] With the development of domestic power distribution technology, there are many kinds of existing steel profiles, the most typical of which are C profiles and 8MF profiles. Profiles of this structure are widely used. The advantages are simple structure, flexible combination, easy installation, and the cost is much lower than aluminum profiles of the same specifications.

[0003] Since the above two commonly used profiles have their own advantages and disadvantages, for example, due to the simple assembly structure of C profile, its rigidity and strength after assembly are poor, and the load capacity after being assembled into a switch cabinet is limited. Especially after being used in a large number of primary distribution equipment, its stability and cabinet strength cannot meet the requirements of high strength and dynamic stability of the switch cabinet during the operation of the distribution cabinet. The strength of 8MF profile is better than that of C profile, but after 8MF profile is made of hot-rolled steel plate, it still needs to undergo welding, grinding, pickling, phosphating, spraying and other processes. The manufacturing process is complicated and not environmentally friendly. At the same time, there is a certain resistance during rapid disassembly. Utility Model Content
