Lock Catch Structure for Adjustable LED Screen Frame Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock catch structures for LED screen frames are limited in their ability to adjust connecting angles and do not facilitate multi-angle or angle transformation, leading to inefficiencies and resource waste, especially when frames need to be dismantled after use.
Innovation Solution
A lock catch structure comprising oppositely arranged first and second lock catch main bodies with rotational connections, inclined surfaces, and a draw-off locking member, allowing for adjustable locking angles through rotation of the main bodies and handle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing lock catch structures are used for LED screen frames, then the connection is simple and straightforward, but the connecting angle cannot be adjusted and multi-angle connection is not supported
Solution Approach 1:
The lock catch structure incorporates rotatable main bodies that can dynamically adjust their orientation. The first main body rotates relative to the first base, and the second main body rotates relative to the second base, enabling the inclined surfaces to achieve different relative angles. This dynamic adjustment capability allows the structure to adapt to various connecting angles while maintaining a relatively simple overall design.
Solution Approach 2:
The lock catch structure is divided into independent rotatable components (first main body and second main body) that can be adjusted separately. Each main body can rotate independently to achieve the desired angle, and the draw-off locking member can also be operated independently to secure the connection. This segmentation allows for angle adjustment without requiring complete structural redesign.
2Adaptability or versatility
If lock catch structures are designed for specific purposes and angles, then the locking function is optimized for that purpose, but the structure cannot be reused for other purposes causing resource waste
Solution Approach 1:
The lock catch structure is designed with universal adaptability through its rotatable main bodies and adjustable inclined surfaces. The same structure can be used for different connecting angles and potentially different applications by simply adjusting the rotation angles, eliminating the need to design and manufacture separate lock catch structures for each specific purpose or angle requirement.
Solution Approach 2:
The structure allows changing the connecting angle parameter by rotating the main bodies to different positions. This parameter adjustment capability enables a single lock catch structure to serve multiple purposes by simply changing its geometric configuration, rather than requiring different structures for different applications.
3Adaptability or versatility
If LED screen frames are connected at staggered or inclined angles, then the visual effect and installation requirements are met, but existing single-direction lock catch structures cannot accommodate these angle requirements
Solution Approach 1:
The rotatable main bodies provide dynamic angle adjustment capability, allowing the lock catch structure to accommodate various staggered or inclined angle connections required for visual effects and installation requirements. The structure can be easily reconfigured for different angles without complex procedures.
Solution Approach 2:
The draw-off locking member with handle provides easy operation for securing the connection at any adjusted angle. The user simply needs to operate the handle to engage or disengage the locking mechanism, and the structure itself maintains the adjusted angle through its rotational joints without requiring additional tools or complex procedures.

AI summary
The lock catch structure comprises a first lock catch main body and a second lock catch main body. The first lock catch main body comprises a first base and a first main body rotationally connected to the first base; The second lock catch structure comprises a second base, a second main body rotationally connected to the second base, a handle hinged at the base and a draw-off locking member pivoted with the handle through a pivot shaft; one end of the draw-off locking member is limited in the groove, and the handle rotates around the pivot shaft as the support point, so that the draw-off locking member drives the first lock catch main body to move towards the second lock catch main body until the first inclined surface is pressed against the second inclined main surface.
