AI Technical Summary
Existing rubber sealing rings are one-piece structures, which means that when some parts are damaged, the entire ring needs to be replaced, which is wasteful of costs and has insufficient sealing performance.
The design adopts a splicing method, which improves the compressive strength and sealing performance by setting a first frame, a second frame, a frame ball, a reinforcing hoop, an extension ball, and an extension part, and facilitates installation and fixing.
It improves the service life and sealing performance of the sealing ring, reduces replacement costs, and enhances the stability and convenience of the connection.
