Transformer ware body axial closing device

The utility model relates to the technical field of transformers, especially, relate to a transformer ware body axial closing device. The device is including pressing nail piston, spring pipe, shieldcover and fitting pin, press " protruding " shape structure of nail piston for placing upside down, press nail piston stub end lower extreme bilateral symmetry to be equipped with pinhole I, press thediameter and spring internal diameter of pipe phase -match of the little head end of nail piston, press nail piston and spring outside of tubes to be equipped with the shield cover, shield cover upper end I relative position of both sides and pinhole is equipped with pinhole II. This transformer ware body axial closing device reasonable in design, the convenience of device operation put and improved to the shield cover can reduction office, press nail piston and spring pipe and can guarantee that pressurized coil and insulating part packing force when shrink or vibration can not take place great change to reduce the n
