AI Technical Summary

Technical Problem

Traditional rubber seals have a limited range of deformation, making them unable to adapt to fluctuations in the size of the sealing surface. Furthermore, they undergo irreversible deformation after long-term use, resulting in a shortened service life and wasted resources.

Method used

The design employs a split sealing ring structure, utilizing the interlocking fit between the side block and the side groove, as well as the interlocking structure between the elastic material protrusion and the channel. Combined with the high strength characteristics of the anti-deformation steel wire, the adjustable deformation of the sealing ring is achieved. The outer circumference size of the sealing ring is adjusted by inserting the protrusion into different channels, and the anti-deformation steel wire is embedded in the component to suppress irreversible deformation.

Benefits of technology

This allows the sealing ring to flexibly adapt to changes in the sealing surface size, extending its service life and reducing resource waste and maintenance costs.

Abstract

The application relates to a sealing ring structure, belonging to the technical field of sealing rings, which comprises a sealing ring main body, the sealing ring main body comprising a first component and a second component, two side blocks being fixedly connected to one side of the first component close to the second component, a side groove being arranged in the second component and cooperatively matched with the side blocks, and the side groove being clamped with the corresponding side block. The sealing ring main body is connected through the clamping cooperation of the side blocks and the side groove by virtue of the split design of the first component and the second component, meanwhile, the relative position of the two components can be flexibly adjusted according to the actual size deviation of the sealing surface by the clamping structure of the convex block and the channel made of elastic material, and after the sealing ring main body is deformed after long-time use, the outer peripheral size of the sealing ring main body is changed by inserting the convex block into different channels, thereby solving the problems that the deformation range of the traditional integrally-formed sealing ring main body is limited and the sealing ring main body cannot adapt to the size fluctuation of the sealing surface.
