Abstract

The invention discloses a hinge. The hinge comprises a hinge base, a square steel rotating shaft and hinge pins. The hinge base comprises a bent plate. The bent plate is provided with a first verticalplate and a second vertical plate, and the first vertical plate and the second vertical plate form a bending corner. The first vertical plate is provided with a containing opening used for containingthe square steel rotating shaft, and the upper end and the lower end of the first vertical plate are provided with lugs. Any lug forms an installation hole used for installing the corresponding hingepin in the vertical direction. The square steel rotating shaft comprises a rotating shaft body, and the upper end and the lower end of the rotating shaft body are provided with hinge shaft holes. After the hinge shaft hole located in the upper end aligns to the installation hole located in the upper end and the hinge shaft hole located in the lower end aligns to the installation hole located in the lower end, the square steel rotating shaft can be installed to the lugs through the hinge pins, so that the square steel rotating shaft can rotate relative to the lugs. The invention further discloses a power distribution box body comprising the hinge. According to the hinge, welding is not needed, the bearing load of the square steel rotating shaft is high, machining is easy, installation is convenient, the hinge is not affected by the material thickness, spraying or other factors, and the cost is low.

Description

Technical field [0001] The invention relates to the technical field of power distribution boxes, in particular to a power distribution box and its hinge. Background technique [0002] As we all know, hinges, also known as hinges, are mechanical devices used to connect two solid bodies and allow relative rotation between them. The hinge may be composed of movable components or of foldable material. [0003] Regarding the hinges used for distribution boxes and power distribution cabinets in the prior art, they are usually formed by die-casting of zinc alloy, which has high cost, brittle material and easy to break. The installation method is to open a notch on the door panel, and use a pin to be stuck at the folding edge of the door panel. If there is an error in the thickness of the plate or uneven spraying, it will be inconvenient to install and easily damage the sprayed layer. Summary of the invention [0004] The purpose of the present invention is to provide a power distributio...
