Power supply charging box

Abstract

The invention discloses a power supply charging box. The power supply charging box comprises a power supply outer shell, the two sides of the power supply outer shell are provided with flanges, a mainboard is arranged at the upper ends of the two flanges, the main board is installed on the upper end surfaces of the flanges through screws, a power supply module is arranged on the main board, and apower supply negative wire and a power supply positive wire are arranged at the input end of the power supply module; a fixed tube is arranged at the bottom of the main board, an integrated structureis arranged between the fixed tube and the power supply outer shell, the fixed tube is equal to the power supply outer shell in length, the end face is opened and the other end face is sealed, a movable cavity is formed in the middle of the fixed tube, and a circular connecting piece is arranged in the movable cavity. The power supply charging box has very good waterproof sealing performance andheat dissipation and ventilation performance, and can be effectively applied to outdoor occasions, and the power line can realize effective expansion, so that the power line is prevented from being pulled to drag the whole power supply main machine due to the good telescopic sliding performance, and therefore the power supply charging box can be applied to a complex outdoor environment.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a charging box for a power supply. Background technique [0002] Charging boxes for outdoor use require better waterproof performance. Traditionally structured charging boxes are generally equipped with heat sinks on the top or bottom. When it rains, rainwater will enter the interior through the heat sinks, resulting in a short circuit of the entire charging box. [0003] In addition, the power input line is directly connected to the main unit of the charging box. When the power input line pulled out from the outside is involved, the entire main unit will be dragged accordingly, and the power plug at one end of the power input line will also be separated from the socket. . [0004] Furthermore, the length of the power input line cannot be adjusted. Many times we don’t need a longer line, and sometimes we feel that the length of the power input line is not enough, so there will be m...
