Abstract

The auxiliary hole sealing structure comprises a sealing plug fixedly installed in an auxiliary hole, the sealing plug comprises a first part located in the auxiliary hole and a second part located outside the auxiliary hole and abutting against the end face of an opening of the auxiliary hole, and a sealing ring groove is formed in the end, close to the second part, of the auxiliary hole. An elastic sealing piece is arranged in the sealing ring groove, and when the sealing plug and the auxiliary hole are assembled, the first part, the second part and the sealing ring groove extrude the sealing piece, so that the sealing piece deforms and fills a space defined by the first part, the second part and the sealing ring groove; through the arrangement, the inner side of the sealing piece is tightly attached to the outer wall of the first part, the outer side of the sealing piece is tightly attached to the inner wall face of the sealing ring groove, a sealing structure located above the auxiliary hole and between the first part and the sealing ring groove is formed, the sealing effect can be improved, the whole sealing piece is located between the sealing plug and the sealing ring groove, and the sealing effect is improved. And oxidation caused by contact with the outside is effectively prevented.
