Description

Relay sealing structure capable of preventing oil leakage Technical Field The utility model relates to the technical field of relay sealing structures, in particular to an oil leakage preventing relay sealing structure. Background Before the relay performs dynamic oil pressure acceleration action test ‌ or ‌ oil flow sensitivity detection, the opening on the relay shell is plugged through the sealing structure, so that the leakage of transformer oil filled in the relay can be avoided, and the accuracy of relay detection is ensured. At present, in the use process of the existing sealing structure, the sealing structure is inconvenient to assemble on the opening of the relay shell, and the connecting and fixing effect of the sealing structure at the opening is poor, so that in order to improve the technical progress of industry, the sealing function of the opening of the relay shell is better realized, the core technical competitiveness is improved, and the application provides a new implementation scheme which is different from the sealing structure in the prior art. Disclosure of utility model The utility model aims to solve the problems that the sealing structure is inconvenient to assemble on an opening of a relay shell and the sealing structure is poor in connecting and fixing effect at the opening in the use process of the traditional sealing structure, and provides an oil leakage-proof relay sealing structure. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a relay seal structure of leak protection oil, includes seal assembly, seal assembly is including the screw head, the one end fixedly connected with threaded rod of screw head, and the outer wall threaded connection of threaded rod has coupling nut, and coupling nut's one end fixedly connected with first spacing ring, the joint has first sealing washer in the first spacing ring, the one end fixedly connected with second spacing ring of screw head, the joint has second sealing washer in the second spacing ring. Further, the outer wall of the threaded rod is sleeved with a supporting ring, and the supporting ring is located in the first sealing gasket and the second sealing gasket. Further, the supporting ring is a rubber ring and is positioned between the screw head and the connecting nut. Further, the outer wall thread of threaded rod is connected with fastening nut, and fastening nut and coupling nut contact. Further, a groove is formed in one side of the second limiting ring, and a magnet ring is clamped in the groove. Further, one side of the magnet ring is adsorbed with a protective cover, and the protective cover is covered on the outer side of the screw head. Further, the protective cover is an iron cover. The beneficial effects of the utility model are as follows: 1. The screw head and the support ring are inserted into the opening of the relay shell, the connecting nut is screwed down again, so that the first limiting ring and the first sealing gasket are closely attached to the inner surface of the relay shell, the sealing structure is fixedly installed in the opening of the relay shell, the operation is simple, the fastening nut is screwed down to fasten, and the connecting and fixing effect of the sealing structure at the opening is improved. 2. And the first sealing gasket and the second sealing gasket form internal and external double seals, so that the sealing performance of the sealing structure is improved. 3. The protecting cover is adsorbed on the magnet ring, so that the protecting cover is covered at one end of the screw head, the impact of external force on the screw head is prevented, and the loosening of the sealing structure is further prevented.
