Compression Sleeve Tube Joint for Faster Metal-Plastic Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting metal and plastic tubes are cumbersome and time-consuming, requiring multiple steps and complex installation processes, making construction inconvenient.
Innovation Solution
A connecting joint design featuring a first compression sleeve on a second tube connecting section with an annular groove, allowing for a simplified connection by inserting a metal tube into a first tube connecting section, welding, and then using a compression tool to deform the sleeve for a fixed connection with a plastic tube, which is inserted into an annular cross-section hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plastic part is removed and reinstalled after welding the metal tube to the connecting joint, then the metal tube and plastic tube can be connected, but the installation process becomes cumbersome and time-consuming
Solution Approach 1:
The compression sleeve is pre-installed on the connecting joint before welding, and the plastic tube can be directly inserted into the compression sleeve without removing any parts. This preliminary arrangement of components eliminates the need for disassembly and reassembly operations, thereby improving installation efficiency and convenience
2Device complexity
If multiple connection steps are required (remove plastic part, weld metal tube, reinstall plastic part), then secure connection is achieved, but the connection process becomes complex
Solution Approach 1:
The connection structure is segmented into distinct functional components: a connecting joint for metal tube welding, a compression sleeve for plastic tube fixation, and an integrated design that allows independent operation of each component. This segmentation enables simultaneous presence of both components without interference, reducing process complexity while maintaining connection reliability through specialized functions of each segment
Solution Approach 2:
The compression sleeve acts as an intermediary component that mediates between the connecting joint and the plastic tube. It provides a dedicated interface for plastic tube insertion and compression, eliminating the need to remove the plastic part from the connecting joint. This intermediary structure simplifies the connection process while ensuring secure fixation of the plastic tube

AI summary
The present disclosure relates to a connecting joint, including a connecting tube and a first compression sleeve. The connecting tube includes a first tube connecting section for connecting a first tube and a second tube connecting section for connecting a second tube. The first tube connecting section and the second tube connecting section are communicated and an annular connecting plate is arranged therebetween. The first compression sleeve is sleeved on the second tube connecting section. A first insertion hole with an annular cross-section for the second tube to be inserted into is formed between an inner wall of the first compression sleeve and an outer wall of the second tube connecting section. A first annular groove is formed in an outer surface of one end of the second tube connecting section close to the annular connecting plate. An end portion of one end of the first compression sleeve close to the annular connecting plate is bent toward the second tube connecting section and inserted into the first annular groove. The connecting joint provided by the present disclosure can simplify the connection of the connecting joint and the plastic tube and save installation time and is convenient to install.
