AI Technical Summary
Technical Problem
The existing pipe joints are not sealing well enough, and the sealing effect is significantly weakened during vibration, resulting in poor shock absorption.
Method used
It adopts a dual-sealing structure, including a rubber sealing ring and an expansion sealing mechanism, as well as a damping shock absorber ring. It uses high-pressure gas and damping fluid to absorb vibration energy, achieving dual sealing and shock absorption functions.
Benefits of technology
It improves the sealing effect, reduces the impact of vibration on the seal, and enhances the overall sealing performance and shock absorption capacity of the pipe joint.

Abstract
This utility model discloses a pipe joint with a highly efficient sealing structure, including a metal joint pipe, an annular shell, an expansion sealing mechanism, a damping shock absorber ring, and a rubber sealing ring. A boss is fixed in the middle of the interior of the metal joint pipe, and a rubber sealing ring is adhered and fixed to both sides of the boss. An expansion sealing mechanism extending into the interior of each of the left and right halves of the metal joint pipe is installed. An annular shell is fixed at both ends of the metal joint pipe, and damping fluid is stored inside the annular shell. The damping shock absorber ring is adhered and fixed to the outside of the metal joint pipe with adhesive. This utility model provides a double seal, resulting in a better sealing effect and excellent shock absorption, reducing the impact of vibration on the seal.
