Anti-loose Socket Pull-out Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-loose sockets fail to securely lock a plug in place under general external forces, requiring specific mechanisms to be opened for the plug to be pulled out, which complicates usage.
Innovation Solution
An anti-loose socket with a pull-out locking mechanism featuring a beveled sleeve and cylinder system, where the cylinder moves along the beveled surface due to a spring and friction force, securely locking the plug until the mechanism is actuated to release it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plug is inserted into a conventional socket, then the plug can be easily removed, but the socket cannot securely lock the plug against external forces
Solution Approach 1:
The socket employs a dynamic locking mechanism where the cylinder can move between locked and unlocked positions. The bevelled sleeve with conical surface allows the cylinder to be pushed by spring force into a locked position against the plug, or retracted when actuated by the operating lever, enabling the plug to be securely held or easily removed as needed
Solution Approach 2:
The spring-loaded cylinder automatically engages with the plug upon insertion, locking it in place without requiring user intervention. The mechanism self-activates through the spring force pushing the cylinder against the plug, providing automatic security while maintaining ease of removal through the operating lever
2Reliability
If a locking mechanism is added to secure the plug, then the plug security is improved, but the device structure becomes more complex
Solution Approach 1:
The operating lever combines multiple functions: it actuates the locking mechanism by moving the floating block and cylinder, simultaneously provides a user interface for operation, and integrates with the spring-loaded system. This merging of functions reduces the need for separate components and simplifies the overall structure
Solution Approach 2:
The bevelled sleeve with conical surface serves multiple purposes: it guides the cylinder during movement, provides a mechanical advantage for the spring force to lock the cylinder in place, and allows easy release when pressure is applied. This multi-functional design element reduces the need for additional guiding mechanisms or release structures
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
The mechanism effectively secures the plug against general external forces, preventing easy removal until intentionally unlocked, ensuring secure and convenient operation.
Implementation Method 1
a spring (10) on the supporting rod (9) is connected to the connecting rod (6) on one end, and is connected to the boss (2) on the other end
Implementation Method 2
the cylinder is mounted on a floating block movable up and down, and can move up and down along the inside conical surface of the bevelled sleeve by the floating block

AI summary
The present invention relates to an anti-loose socket and a pull-out locking mechanism thereof, wherein inside the anti-loose socket, there are a pull-out locking mechanism composed of a bevelled sleeve (15) and two cylinders (16) arranged in a symmetrical manner at two sides within the bevelled sleeve; an inside longitudinal section of the bevelled sleeve has a cone angle in an umbrella shape, the middle portion of the bevelled sleeve allows a plug pin (61) to pass through; the cylinder is mounted on a floating block (14) movable up and down, and can move up and down along the inside conical surface of the bevelled sleeve by the floating block. When the plug (6) is pulled out upwards, the cylingder moves upwards due to the action of a friction force and a elastic force, however due to the limiting action of the bevel surface, the cylingders stick to the two bevel surfures more and more tightly, so as to form a self-locking, such that the plug cannnot be pulled out or cannnot be easily pulled out; when the cylinders drop down, the plug can be conveniently pulled out.
