Rotating Sleeve Locking Mechanism for Power Cord Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting and fixing structures for power cords and electrical appliances, such as buckles and screws, are inconvenient and time-consuming for disassembly and assembly.
Innovation Solution
A connecting-fixing structure featuring a connection end with a locking member and a rotating sleeve, where the locking member rotates to engage or disengage with a locking fitting portion on the power cord, allowing for easy assembly and disassembly by rotating the sleeve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If buckles or screws and fixtures are used to fix power cords, then the power cords can be detachably fixed, but the operation is inconvenient and time-consuming for disassembly and assembly
Solution Approach 1:
The locking member is designed to rotate between locked and unlocked positions, transforming the static fixing structure into a dynamic one. The rotating sleeve enables the locking member to pivot, allowing the locking portion to engage or disengage from the locking fitting portion through rotational motion, making disassembly and assembly convenient while maintaining reliable fixing
2Reliability
If buckles or screws and fixtures are used to fix power cords, then the power cords can be detachably fixed, but it is time-consuming to disassemble and assemble the power cords
Solution Approach 1:
The rotating sleeve and locking member create a dynamic fixing mechanism that can be quickly activated or deactivated. Users can disassemble or assemble the power cord by simply rotating the sleeve, which pivots the locking member into or out of the locked position, dramatically reducing the time required compared to traditional buckles or screws
Solution Approach 2:
The fixing structure is segmented into distinct functional components: the rotating sleeve for operation, the locking member for engagement, and the locking portions for connection. This segmentation allows each component to perform its specific function efficiently, enabling rapid disassembly and assembly while maintaining secure fixing

AI summary
A connecting-fixing structure, used for detachably connecting a main body of an electrical appliance with a power cord, includes a connection end, a locking member, and a rotating sleeve. The locking member includes a supporting shaft and a locking portion which rotates by the supporting shaft as a fulcrum. A locking fitting portion is disposed on the tail end of the power cord and adapted to the locking portion. Furthermore, a rotating sleeve is rotatably sleeved on the connection end, an inner wall of the rotating sleeve has a driving part, and the rotating sleeve rotates to drive the driving part to further drive the locking portion to rotate, thereby locking the locking portion or unlocking the locking portion from the locking fitting portion. The power cord can be disassembled and assembled only by rotating the rotating sleeve, and the operation is convenient, and the structure is simple.
