Quick-Plug Sealing Cover Structure for Corrosion-Free Fluid Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The internal connection structure of sealing covers with quick-plug interfaces is complex, leading to multiple sealing points and potential air leakage, and metal materials within these interfaces corrode when exposed to corrosive fluids, causing damage and leakage over time.
Innovation Solution
A sealing cover with a quick-plug interface design that uses a flexible annular sealing member and a plastic fixing sleeve, both clipped to the inner wall of a through hole, eliminating metal contact with fluids and incorporating a reverse buckle structure for assembly, reducing the number of internal accessories and minimizing air leakage points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal materials are used in quick-plug connectors, then connection strength and durability are improved, but corrosion occurs when exposed to corrosive fluids, causing damage and leakage
Solution Approach 1:
The patent introduces a plastic shell as an intermediary protective layer between the metal quick-plug connector and the corrosive fluid. The metal connector remains enclosed within the plastic shell, which acts as a barrier preventing direct contact between the metal and corrosive substances. This mediator approach preserves the connection strength of metal while eliminating corrosion damage.
Solution Approach 2:
The patent employs a composite structure combining metal and plastic materials. The quick-plug connector consists of a metal core component enclosed within a plastic shell, creating a composite assembly that leverages the strength of metal and the corrosion resistance of plastic. This composite material approach resolves the contradiction by integrating materials with complementary properties.
2Reliability
If complex internal connection structure with many sealing points is used, then sealing performance is improved, but the number of sealing points increases the hidden danger of air leakage
Solution Approach 1:
The patent merges multiple sealing functions into a single integrated sealing ring component. Instead of having separate sealing elements at multiple discrete points, the design uses one continuous sealing ring that provides sealing across the entire interface between the cap and the quick-plug connector. This consolidation maintains sealing performance while reducing the number of potential leakage points.
Solution Approach 2:
The patent employs a flexible sealing ring made of elastomeric material that can deform to conform to the mating surfaces. This flexible membrane approach creates an effective seal through elastic deformation rather than relying on multiple rigid sealing points, thereby improving sealing performance while simplifying the overall structure.

AI summary
A sealing cover with quick-plug interface, comprising: cover body, above which a through hole is arranged, and in which a communication hole is arranged, and said through hole is connected with said communication hole; an annular sealing member and an annular fixing sleeve are arranged in said through hole, and said sealing member is arranged at the bottom of said through hole, and said fixing sleeve is arranged above said sealing member; said sealing member and said fixing sleeve are both clipped to an inner wall of the through hole, and said sealing member is made of a flexible material. There is no metal material in contact with the fluid inside the sealing cover with quick-plug interface, so there is no hidden danger of corrosion in long-term use, and the defect that the metal material is not resistant to corrosive fluids is avoided.
