Camera Strap Buckle Locking Structure for Quick Release Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera strap buckles, such as plug-in and metal ring structures, lack sufficient strength and are cumbersome to use, particularly when subjected to the shaking and pulling forces of outdoor photography.
Innovation Solution
A strap buckle design featuring a hanging buckle body with a locking cavity, a buckle member, and a stop pin that allows for quick connection and disassembly, utilizing a spherical buckle member body and a rotatable or slidable stop pin to secure the buckle member within the locking cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plug-in buckle structure is used, then the strap buckle is easy to use, but the connection strength is insufficient
Solution Approach 1:
The buckle is divided into separate components: a buckle body with a locking cavity, a buckle member with a connecting member, and a stop pin. This segmentation allows for both easy assembly/disassembly and strong connection when locked.
Solution Approach 2:
The stop pin is pre-positioned within the locking cavity to automatically engage with the buckle member upon insertion through the connecting groove, ensuring immediate securing without requiring additional locking steps.
2Strength
If a metal ring structure is used, then the connection strength is improved, but the ease of use deteriorates
Solution Approach 1:
The stop pin is designed to be movable within the locking cavity, allowing it to dynamically adjust its position to engage or disengage from the buckle member, enabling both strong connection and easy release.
Solution Approach 2:
The stop pin acts as an intermediary element between the buckle body and buckle member, mediating the connection by engaging with the buckle member's protruding structure to provide secure locking while allowing controlled disengagement.
3Ease of operation
If a spherical buckle member is used, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The buckle member is designed with a spherical body that can rotate freely, allowing users to easily orient and position it during connection and disassembly operations, simplifying the user interaction despite the added structural elements.

AI summary
A strap buckle and an operation method therefor. The strap buckle includes a hang buckle main body, a fastener and a stop pin, wherein the hang buckle main body is configured to connect to a strap; the fastener is configured to connect to any position; the buckle main body is connected to the fastener, so as to be used for connecting the strap to any position; a locking cavity is arranged in the hang buckle main body, and the hang buckle main body is provided with a buckling slot; at least part of a structure of the fastener enters the locking cavity by means of the buckling slot; and the stop pin is movably arranged on the hang buckle main body, and the stop pin is configured to prevent the part of structure that enters the locking cavity from being separated from the interior of the locking cavity.
