Outdoor cabinet and top cover thereof

The invention relates to an outdoor cabinet and a top cover thereof. The outdoor cabinet comprises a cabinet and a top cover. The cabinet comprises a cabinet body and a cabinet door. One in the cabinet body and the cabinet door is provided with a water guiding trough which extends to two sides of the cabinet. The water guiding trough exists in a clearance between the cabinet body and the cabinet door. According to the outdoor cabinet, in the actual use process, the water guiding trough is blocked in the clearance between the cabinet body and the cabinet door.
