Abstract
The utility model discloses a novel transformer body elastic pressing device. The novel transformer body elastic pressing device comprises a pressing nail, a pressing cover, an outer shell and an elastic gasket, the pressing nail is arranged on a support through a loosening nut, the elastic gasket is arranged in the outer shell, the pressing cover is arranged on the elastic gasket, and the bottom of the pressing nail is abutted on the pressing cover. The pressing cover is of a concave shape with an upper edge, the inner diameter of the concave portion in the center of the pressing cover is matched with the pressing nail, the outer diameter of the concave portion is matched with the inner diameter of the outer shell, and the outer diameter of the upper edge is larger than the inner diameter of the outer shell. A through hole is formed in the center of the bottom of the concave portion, a locating hole is formed outside the pressing cover, and a communicated T-shaped through hole is formed in the lower portion of the pressing nail along the axial line and the diameter. The T-shaped through hole and the through hole in the bottom of the pressing cover form an air channel, a locating cavity is arranged on a side portion of the outer shell, and locating pins can be arranged in the locating cavity and the locating hole when the pressing cover contacts the outer shell. An oil hole is formed in the bottom of the outer shell. A pressing stroke limiting component is arranged in the novel transformer body elastic pressing device, pressing force can be controlled well, and a pressing state can be kept, and therefore installation is convenient, and dead oil areas and suffocation can not happen.
