Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to a bottom plate flip-out type power distribution cabinet. Background Art

[0002] When assembling a distribution cabinet, a mounting plate is often set on the rear wall, and the mounting plate is used to install components such as tracks and terminal posts, so as to facilitate fixing electrical components to the mounting plate through the tracks; when the distribution cabinet is first assembled, a small distribution cabinet generally directly assembles electrical components on the mounting plate, and then uniformly installs the mounting plate into the distribution cabinet, while for some large distribution cabinets, if the electrical components are assembled on the mounting plate first, the mounting plate will be too heavy to be transferred into the distribution cabinet, so it is necessary to first fix the mounting plate in the distribution cabinet, and then install the electrical components on the mounting plate; and the installation position of the mounting plate in the distribution cabinet is often parallel to the rear wall of the distribution cabinet. When wiring the electrical components, the wiring ports located on the upper and lower sides of the electrical components are difficult to be observed due to the angle, especially in the later maintenance / replacement of the electrical components, the phenomenon of the line of sight being blocked due to the influence of wiring is more obvious. Utility Model Content

[0005] In the above structure, the mounting plate is fixed by a connecting rod mechanism so that the lower end of the mounting plate can be flipped up and swung as needed, or the upper end of the mounting plate can be flipped down and swung as needed. After the swing, the mounting plate is at an angle relative to the rear wall of the cabinet, so that the wiring ports on the upper and lower sides of the electrical components on the mounting plate are turned outward, which is convenient for wiring.
