Hinge Structure With Clipping Strip And Limiting Slot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hinge structures are complex, leading to increased production costs and a lack of a positioning mechanism to fix the relative rotation angle between connected objects, resulting in potential damage and reduced service life due to excessive force.
Innovation Solution
A hinge structure featuring a first connecting piece with a slot and a second connecting piece with a rotating shaft, where the slot has a limiting slot and the rotating shaft has a convex clipping strip to limit the rotation angle, allowing for a simple and fixed relative rotation between the two pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional hinge structure is used, then the connection between two objects is achieved, but the structure becomes complex and production cost increases
Solution Approach 1:
The patent combines the hinge body and positioning mechanism into a single integrated structure. The positioning groove is directly formed on the hinge body, and the positioning protrusion is integrated on the connecting piece, eliminating the need for separate positioning components and reducing structural complexity while maintaining the hinge's connection and rotation functions
Solution Approach 2:
The hinge body serves multiple functions: it provides the connection between two objects, enables relative rotation, and incorporates the positioning mechanism through the integrated positioning groove. This multi-functionality reduces the number of separate components needed, simplifying the overall structure and lowering production costs
2Reliability
If a traditional hinge without positioning mechanism is used, then the structure remains simple, but the rotation angle cannot be fixed leading to potential damage
Solution Approach 1:
The positioning mechanism is merged with the hinge body structure itself. The positioning groove is formed directly on the hinge body, and the positioning protrusion is integrated on the connecting piece, creating a unified structure that provides both connection and positioning functions without adding separate complex mechanisms
Solution Approach 2:
The hinge structure performs self-positioning through the interaction between the positioning protrusion and positioning groove. When the connecting piece rotates to a specific angle, the protrusion engages with the groove to automatically limit the rotation angle, providing self-regulating protection against excessive force without requiring external control mechanisms

AI summary
The application provides a hinge structure comprising a first connecting piece provided with a slot and a second connecting piece provided with a rotating shaft. An inner wall of the slot is provided with a limiting slot and an outer surface of the rotating shaft is convex to form a clipping strip; the clipping strip is inserted into the limiting slot to limit a relative rotation angle between the first connecting piece and the second connecting piece. The present application also provides a packaging box comprising the above hinge structure. The hinge structure and the packing box are provided with a limiting slot in the slot and a clipping strip on the rotating shaft. Through the cooperation between the clipping strip and the limiting slot, the relative rotation angle between the first connecting piece and the second connecting piece is fixed and the reliability of the hinge structure is improved.
