Quick Clamping Hoop Assembly With Plug Connection and Sealing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick connection clamping hoops face inefficiencies in assembly and pipe connection due to bolt-based connections, sealing ring deformation, and integration with retaining rings leading to sealing failures.
Innovation Solution
The design includes semi-annular upper and lower clamping hoop bodies with plug connecting ends and a plug connecting mechanism, adjustable sealing ring grooves, and a non-integral retaining ring to facilitate quick assembly and ensure effective sealing by allowing for the sealing ring's free contraction and preventing deformation-induced sealing failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolt connections are used to connect upper and lower clamping hoop bodies, then the connection is reliable, but assembly efficiency and connection speed are reduced
Solution Approach 1:
The clamping hoop is divided into upper and lower semi-annular bodies that can be assembled separately and then connected. This segmentation allows for pre-assembly of components and faster on-site connection compared to traditional one-piece designs with multiple bolts
Solution Approach 2:
The upper and lower clamping hoop bodies are merged into a single integrated structure after assembly, eliminating the need for multiple separate connection points. The end-to-end connection merges the two halves into a complete circular clamp that maintains reliable holding force
2Ease of manufacture
If uniform groove depth is used from middle to end parts, then manufacturing is simplified, but sealing ring deformation causes protrusion and sealing failure
Solution Approach 1:
The groove depth is varied locally along the clamping hoop - deeper in the middle section and shallower at the end parts. This local variation in groove depth allows the sealing ring to deform uniformly under compression without protruding at the ends, maintaining sealing reliability while accommodating the non-uniform pressure distribution
3Strength
If retaining ring is firmly connected to sealing ring body, then structural integrity is improved, but sealing ring contraction is hindered causing corrugation and sealing failure
Solution Approach 1:
The connection between the retaining ring and sealing ring body is made flexible rather than rigid. This dynamic connection allows the sealing ring to contract and deform as needed during operation while the retaining ring maintains its structural integrity and prevents the sealing ring from collapsing or forming harmful corrugations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances assembly efficiency, improves pipe connection speed, and maintains a sealing effect by allowing the sealing ring to deform without protruding and preventing bonding with the retaining ring, ensuring full contact and preventing sealing failures.
Implementation Method 1
when the clamping hoop is sleeved on the pipe for fastening, the sealing ring is deformed under pressure
Implementation Method 2
the hook of the connecting arm is capable of being hooked on the connecting post after the connecting arm is inserted into the inserting hole
