Embodiment Construction
[0014] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0015] An outlet box for high-voltage electrical appliances, connected to the wall of the high-voltage electrical appliance, including an outlet box cover 1, a wing nut 3, a pressure ring 4, a stud 5, a hinge, and a box wall 7. The box wall is an integral cylindrical structure 2, The upper edge of the cylindrical structure is bent outward 8, and the outlet box cover is set on the bent edge. The hinge is composed of a fixed leaf and a rotating leaf that match each other. The rotating leaf is a rotating shaft structure, and the fixed leaf is a hollow cylindrical structure. The fixed leaf is arranged outside the cylindrical structure, the rotating leaf is arranged on the outlet box cover, and the rotating shaft of the rotating leaf is inserted into the hollow cylinder of the fixed leaf; the cylindrical structure opposite to the fixed leaf is provide...

The invention relates to an outlet box for a high-voltage electric appliance, and belongs to the technical field of high-voltage electric appliances. According to the technical scheme, the outlet box comprises an outlet box cover (1), a butterfly nut (3), a pressing ring (4), a stud (5), a hinge and a box wall (7). The box wall is wholly of a barrel-shaped structure (2). The upper edge of the barrel-shaped structure is outward to form a flange (8). The outlet box cover is arranged on the flange. The hinge is composed of a fixed hinge body (6) and a rotating hinge body, wherein the fixed hinge body and the rotating hinge body are matched. The outlet box cover is tightened to the flange of the upper edge of the barrel-shaped structure through the butterfly nut. The pressing ring is transversely arranged in the middle of the barrel-shaped structure, a connecting hole is formed in the pressing ring, and a bolt penetrates through the connecting hole to make a terminal board and the box wall of the high-voltage electric appliance fixed together. An outlet pipe (10) is arranged on the side face of the barrel-shaped structure. The outlet pipe and the box wall are of an integrated structure. The outlet box has the advantages that materials are saved, time and labor are saved in the machining and assembling process, and the outlet box cover is effectively prevented from being lost.
