Tube Quick-Release Assembly with Bidirectional Engaging Buckle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tube connectors for quick connection and disconnection of pipelines lack directional functionality and are prone to displacement due to fluid pressure changes, leading to increased complexity and production costs in manufacturing.
Innovation Solution
A tube quick-release assembly featuring an inner plug with a second annular boss and an engaging buckle with hooks that securely engage with the outer socket, allowing for bidirectional quick connection and disconnection without the need for complex mold structures or additional raised legs, reducing manufacturing costs and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sleeve is provided with protruding legs having hooks and the outer socket is provided with engaging holes and guide grooves, then the connection between sleeve and outer socket is achieved, but the manufacturing complexity and production costs increase
Solution Approach 1:
The patent combines the engaging buckle and sleeve into a single integrated component. The engaging buckle is formed as one piece with the sleeve, eliminating the need for separate engaging mechanisms. This merging reduces mold complexity and production costs while maintaining the connection function between the inner plug and outer socket.
2Reliability
If the outer socket is provided with two suspended arms that are reduced inward, then the inner plug is restricted from displacing, but the manufacturing complexity and production costs increase
Solution Approach 1:
The patent integrates the restricting function previously performed by separate suspended arms into the engaging buckle component. The engaging buckle, when engaged with the outer socket, inherently restricts the inner plug from displacing due to fluid pressure changes. This integration eliminates the need for additional suspended arms and reduces manufacturing complexity.
3Productivity
If the inner plug is movably inserted in the stepped inner hole with sealing connection, then the quick connection and disconnection is achieved, but the displacement under fluid pressure affects service life
Solution Approach 1:
The engaging buckle is pre-configured with hooks that engage with the outer socket to prevent displacement before fluid pressure changes occur. This preliminary anti-action ensures the inner plug remains stable under fluid pressure, extending service life while maintaining quick connection efficiency.

AI summary
A tube quick-release assembly includes an outer socket and an inner plug. The inner plug is movably inserted in the outer socket. An upper portion of the outer socket is formed with two opposing engaging openings. An engaging buckle is fitted on the inner plug. The engaging buckle is provided with two opposing engaging legs having hooks and flaring outward. The hooks of the engaging buckle radially engage with the two engaging openings of the outer socket to realize a quick connection of tubes. The two hooks of the engaging buckle can be pressed inward to realize a quick disconnection of tubes.
