Anti-bending power distribution box with waterproof top cover

Abstract

The invention discloses an anti-bending power distribution box with a waterproof top cover. A box body is set to be of a hollow cylindrical structure, and the top cover is set to be an inclined top plane, wherein the height of the inclined top plane gradually decreases from the back to the front. Two side edges of the inclined top plane are provided with vertically downward bent edges, and a position parallel to the bent edges is provided with an arc-shaped projection. An end part of the arc-shaped projection is provided with a rainproof groove cover, and the projection perpendicular to the root of the rainproof groove cover is provided with heat-dissipation holes. The inner wall of the top cover is provided with a supporting plate which is used for fixing a power distribution box plate. A side surface of the supporting plate is provided with a connecting rod, and the connecting rod is provided with a rotating wheel. The rotating wheel is controlled by a motor to rotate. Two end parts of the rotating wheel are respectively connected with an arched vibration-resistant steel ring, and the arched vibration-resistant steel ring is clamped with an opening of the box body. The box is simple in structure, is good in waterproof performance, is high in installation stability, reduces the cost, is strong in anti-bending capability, and is strong in vibration resistance.

Description

Technical field [0001] The invention belongs to the technical field of power distribution box equipment, and in particular relates to an anti-bending power distribution box with a waterproof top cover. Background technique [0002] The distribution box is to assemble the switchgear, measuring instrument, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements to form a low-voltage power distribution device. During normal operation, the circuit can be turned on or off by means of a manual or automatic switch. Power distribution boxes, power distribution cabinets, power distribution boards, power distribution panels, etc., are complete sets of equipment for centralized installation of switches, meters and other equipment. At present, the common outdoor distribution box is placed directly outdoors and its rear wall is not close to the wall. Therefore, when designing this type ...

Problems solved by technology

However, the surrounding edges of the top cover designed with this structure generally protrude from the periphery of the vertical box of the distribution box in a large size, do not have bending resistance, and the service life is relatively short, and the contact surface between the top cover and the distribution box body is small , when the contact surface becomes smaller, the solution slides out of the surface of the distribution box board under the adjustment of excessive wind force or rainstorm, which is easy to damage and poses a safety hazard to the wiring inside the distribution box
