Pipe Joint Structure With Auxiliary Retaining Ring And Lock Nut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe joint structures exhibit a weaker fixation force, leading to separation of the brass pipe from the joint under pull force, resulting in scratches and leakage issues during re-jointing.
Innovation Solution
A pipe joint structure incorporating a joint body, O-ring seal piece, auxiliary retaining ring, lock nut, and connecting base, where the lock nut is tightly locked to push the auxiliary retaining ring and spring plates forward, utilizing metal claws to securely embed the brass pipe, preventing separation and scratches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If break gear teeth of the snap ring are used to embed the brass pipe, then the pipe joint structure is simple, but the fixation force is weak
Solution Approach 1:
The invention divides the fixing function into multiple components: the connecting base with spring plates provides initial embedding, the auxiliary retaining ring with inclined plane provides additional constraint, and the lock nut with stepped blocking portion provides final locking. This segmentation allows each component to contribute to fixation force while maintaining overall structural simplicity.
Solution Approach 2:
The spring plates are designed to be elastic and deformable, allowing them to dynamically adapt to the brass pipe during installation and provide continuous fixation force. The auxiliary retaining ring can also deform elastically to engage with the lock nut, creating a dynamic locking mechanism that enhances fixation strength.
2Reliability
If break gear teeth slightly embed the brass pipe, then the structure is simple, but the pipe separates under pull force causing scratches
Solution Approach 1:
The spring plates are pre-configured with undercuts that engage with the brass pipe before any pull force is applied. The auxiliary retaining ring is positioned in advance to provide additional constraint. This preliminary action ensures the pipe is securely held before any separation force acts on it, preventing scratches during normal operation.
Solution Approach 2:
The lock nut with stepped blocking portion provides a preliminary locking action that cushions against pull forces before they can cause separation. The auxiliary retaining ring with its inclined plane also provides advance constraint, creating a buffer that prevents the pipe from being pulled out and scratched during installation or use.
3Ease of operation
If the brass pipe is loosely connected, then installation is easy, but leakage occurs during re-jointing
Solution Approach 1:
The O-ring seal piece is positioned at a specific location within the joint body to provide localized sealing where it is most needed. The spring plates and auxiliary retaining ring provide localized mechanical constraint at the connection point, ensuring both ease of installation and reliable sealing by concentrating fixing and sealing functions at critical locations.
