Clamping Hoop Plug Connection for Fast Pipe Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick connection clamping hoops for pipe connections are inefficient due to the need to rotate two bolts for assembly and connection to a pipe, leading to poor sealing and potential sealing failures.
Innovation Solution
The clamping hoop design features a plug connecting mechanism that allows for quick assembly and disassembly, with only one bolt and nut required for connection, and a sealing ring design with varying groove depths and a non-integral retaining ring to ensure proper sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two bolts are used to connect the upper and lower clamping hoop bodies, then the connection is secure, but the assembly efficiency and connection speed are reduced
Solution Approach 1:
The connection structure is segmented into a plug connecting end and a connecting end. The plug connecting end uses a rapid insertion mechanism with a single bolt, while the connecting end uses the traditional two-bolt configuration. This segmentation allows different parts of the clamping hoop to use different connection methods optimized for their specific functions.
Solution Approach 2:
A plug connecting mechanism acts as an intermediary between the upper and lower clamping hoop bodies at one end. This mechanism includes a plug connecting post and a plug connecting hole that enable rapid connection through simple insertion and single-bolt fastening, eliminating the need for two bolts while maintaining connection security.
2Ease of manufacture
If the groove depth of the sealing ring groove is uniform from the middle part to the end parts, then the manufacturing is simple, but a gap occurs at the end part causing sealing failure
Solution Approach 1:
The sealing ring groove is designed with non-uniform depth: the groove depth at the middle part is greater than the groove depth at the end parts. This local variation in groove depth ensures that the sealing ring maintains proper contact with the clamping hoop bodies throughout, preventing gaps at the end parts while still allowing for effective manufacturing through controlled depth variations.
3Device complexity
If the retaining ring is firmly connected integrally with the sealing ring body, then the structure is simple, but the sealing ring cannot contract freely causing sealing failure
Solution Approach 1:
The retaining ring is extracted from the integral connection with the sealing ring body and made into a separate, independently movable component. The retaining ring can slide along the sealing ring body without being firmly connected, allowing the sealing ring to contract freely when the clamping hoop is tightly locked. This prevents the sealing ring and retaining ring from forming corrugated unevenness and maintains sealing reliability.

AI summary
A quick connection clamping hoop, including an upper clamping hoop body and a lower clamping hoop body that are both in a semi-annular shape; where the upper clamping hoop body and the lower clamping hoop body each have one end as a plug connecting end and the other end as a connecting end; connecting ends of the upper clamping hoop body and the lower clamping hoop body each are provided with a lug, and the connecting ends of the two are connected together via a bolt passing through lugs; plug connecting ends of the two are connected together via a plug connecting mechanism disposed at the plug connecting ends of the two.
