Spigot-and-Socket Pipe Joint Anti-Slip Stopper Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spigot-and-socket conduit joints face issues with complex installation processes, risk of stopper disengagement due to external forces, and corrosion of locking members, leading to unreliable connections.
Innovation Solution
The design incorporates a spigot-and-socket conduit joint with a rubber block fixed in a stopper's fixing hole, providing anti-slip functionality and preventing disengagement, along with an inverted cone fixing column and strategically placed inclines and grooves to facilitate easy installation and resist corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stoppers are fixed using steel strips or locking members, then the stoppers can be bundled and secured, but the installation steps become complicated and the locking members are prone to corrosion
Solution Approach 1:
The patent extracts the stopper from the mounting groove and relocates it to a fixed position on the spigot outer wall. This eliminates the need for steel strips or locking members to bundle multiple stoppers, simplifying the installation process while maintaining reliable fixation through the embedded anti-slip boss structure
Solution Approach 2:
The patent introduces an anti-slip boss as an intermediary element between the stopper and the spigot outer wall. The anti-slip boss is embedded into the spigot wall, creating a robust mechanical connection that eliminates corrosion-prone locking members while ensuring reliable stopper positioning
2Reliability
If steel strips are used to lock stoppers, then stoppers can be secured, but the steel strips directly contact the external environment causing corrosion and invalidation
Solution Approach 1:
The patent removes the steel strip locking member from the system entirely. Instead, the stopper is secured through its anti-slip boss that is embedded into the spigot outer wall, eliminating the component that was susceptible to environmental corrosion
Solution Approach 2:
The patent employs composite material construction where the anti-slip boss (typically metal) is embedded into the spigot outer wall (typically concrete or composite material). This creates a durable, corrosion-resistant assembly that maintains locking function without exposing vulnerable metal components to the external environment
3Reliability
If multiple stoppers are bundled with locking members, then they can be fixed together, but the locking members loose or break due to multiple axial movements
Solution Approach 1:
The patent segments the stopper fixation function, with each stopper having its own anti-slip boss embedded independently into the spigot outer wall. This eliminates the need to bundle multiple stoppers together, allowing each stopper to function independently and preventing the propagation of failure across multiple components
Solution Approach 2:
The patent extracts the bundling function entirely by providing individual fixation for each stopper through embedded anti-slip bosses. This eliminates the steel strips or locking members that would otherwise be subjected to repeated axial movements and potential failure

Function Achieved in This Case
This configuration ensures a reliable, stable connection by preventing stopper disengagement and extending the service life of the joint through reduced exposure to corrosive environments and improved mechanical strength.
Implementation Method 1

AI summary
A spigot-and-socket conduit joint with an anchor structure is disclosed. At least one group of anti-slip bosses is provided on a stopper of the joint. A fixing hole is provided in the panel of the stopper between the projections of every group of bosses. A rubber block is fixed to the stopper through the fixing hole. After the stopper is inserted between the socket and the spigot through the stopper mounting groove in an annual wall at the end of the socket, the stopper is installed in position by rotating circumferentially along the outer wall of the spigot. The rubber block attached to the stopper is located at the right side of the inner incline of the annual wall at the end of the socket, in the meanwhile, the stopper is pressed against the outer surface of the spigot tightly by the rubber block, thus enabling to effectively prevent the stopper from displacing or rather dropping out. The spigot-and-socket conduit joint with the anchor structure according to the invention has simple structure, convenient and rapid installation, better anti-slip capability and wide application.
