LED Screen Edge Locking Structure for Anti-Loosening Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing edge locking structures for LED display screens are prone to loosening, resulting in a poor locking effect due to single-stage driving, which compromises the stability and alignment of adjacent display modules.
Innovation Solution
An edge locking apparatus with a multi-stage linkage mechanism involving a lock seat, lock cylinder, rotating piece, first driving piece, and second driving piece, where the lock cylinder includes a cylinder body part, lock pin, and rotating parts, allowing for synchronized rotation and movement between retracting, inserting, and locking positions, ensuring secure alignment of adjacent LED frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-stage driving piece is used to drive the lock cylinder, then the device complexity is reduced, but the reliability of the locking structure deteriorates due to loosening
Solution Approach 1:
The single-stage driving piece is segmented into two independent driving pieces: a first driving piece that drives the lock cylinder to move between retracting and inserting positions, and a second driving piece that drives the lock cylinder to rotate from the inserting position to the locking position. This segmentation eliminates the loosening problem by separating the linear motion and rotational motion functions, thereby improving reliability while maintaining acceptable device complexity.
2Reliability
If a multi-stage linkage mechanism is introduced to improve locking stability, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking process is segmented into two distinct stages with two separate driving pieces, where each driving piece is responsible for a specific motion stage. This segmentation improves reliability by ensuring each stage is independently controlled, reducing the risk of loosening, while the complexity increase is managed through functional specialization rather than overall system complexity.
Solution Approach 2:
The lock cylinder is designed with dynamic capabilities to perform both linear movement (between retracting and inserting positions) and rotational movement (from inserting position to locking position). This dynamic design allows a single component to handle multiple motion types, improving reliability without requiring additional components for each motion stage, thus balancing reliability improvement with controlled complexity.

AI summary
The invention provides an edge locking apparatus of a Light Emitting Diode (LED) display screen and the LED display screen. The edge locking apparatus of the LED display screen includes an edge locking structure (10). The edge locking structure (10) includes a lock seat (11), a lock cylinder (12), a rotating piece (13), a first driving piece (13) and a second driving piece (14). The lock cylinder (12) is movably arranged in the lock seat (11), and the lock cylinder (12) includes a cylinder body part (121), and a lock pin (122), a first rotating part (123), an avoiding part (124) and a second rotating part (125) which are sequentially arranged on the cylinder body part (121) at intervals. The cylinder body part (121) is provided with a retracting position enabling the lock pin (122) to retract into the lock seat (11), an inserting position enabling the lock pin to extend out of the lock seat and a locking position enabling the lock pin to rotate by a preset angle relative to the inserting position. The rotating piece (13) is rotatably arranged on the lock seat and the rotating piece (13) and the first rotating part (14) are able to rotate synchronously. The first driving piece (14) is movably arranged on the cylinder body part. The second driving piece (15) is rotatably arranged on the lock seat and the second driving piece and the second rotating part are able to rotate synchronously. The technical solution of the invention effectively solves the problem in the related art that the edge locking structure is prone to loosening, so that the locking effect is poor.
