Abstract
Description
Technical Field
[0001] This utility model relates to a novel double-sealed quick connector. Background Technology
[0002] Current quick-connect couplings suffer from the following drawbacks: complex overall structure and poor sealing, leading to certain shortcomings in their use. This invention proposes an improvement solution to address these problems. The applicant proposes an improved, novel double-sealed quick-connect coupling to meet the demands of the current market. Utility Model Content
[0003] This invention provides a straight-through quick-connect connector that can solve the above-mentioned technical problems.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A novel double-seal quick connector, characterized in that it comprises a body and a connector clamp body that are threadedly connected to each other, and a first sealing ring is installed between the body and the connector clamp body; A second sealing ring is installed in the inner cavity of the connector card near the port; A liner is installed inside the body; A sleeve and a third sealing ring are installed between the liner and the connector body. The third sealing ring is snapped into a groove formed on the inner wall of the connector body.
[0005] Compared with the prior art, the beneficial effects achieved by this utility model are: This invention features a compact and low-cost overall structure, achieving quick-connection while maintaining excellent sealing. The invention utilizes a second and third sealing ring to provide a double seal when the connecting pipe is snapped together, improving the sealing performance of the quick-connect and resolving the problem of poor sealing in existing quick-connect couplings.
