LED Display Screen Lock with Rotating Core and Sliding Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional locks used for LED display screens are cumbersome and difficult to operate, especially when the screens need to be lifted and assembled, as they require significant effort to clamp blocks into grooves at various angles.
Innovation Solution
An LED display screen lock is designed with a handle, a lock seat featuring a base, a through hole, and a slidable pin, and a lock core that rotates within the handle and through hole. The lock core has a locking hole for the pin, and an unlocking portion on the handle's circumference abuts the pin to drive it out of the locking hole, allowing for easy locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locks are used to clamp blocks into grooves, then the LED display screen can be locked securely, but it requires significant effort and is difficult to operate, especially when lifted at various angles
Solution Approach 1:
The patent replaces the traditional mechanical block-clamping-groove system with a rotational lock core mechanism. The lock core rotates within the through hole, and the pin slides along the groove to engage or disengage from the locking hole, converting the clamping action into a rotational and sliding motion that is easier to operate
Solution Approach 2:
The lock mechanism transitions from a static clamped state to a dynamic rotational and sliding state. The pin can slide along the groove and the lock core can rotate, allowing the operator to easily switch between locked and unlocked states without applying significant clamping force
2Reliability
If traditional locks are used for LED display screen assembly, then the screen can be secured, but it takes a lot of efforts and time to clamp the block into the groove
Solution Approach 1:
The dynamic rotational and sliding motion of the lock core and pin allows for rapid engagement and disengagement. The operator can quickly rotate the handle to slide the pin into or out of the locking hole, significantly reducing the time required for locking and unlocking operations during assembly
Solution Approach 2:
The replacement of the force-intensive block clamping mechanism with the rotational lock core system eliminates the need for significant manual effort, enabling faster operation and improving overall assembly productivity
3Reliability
If traditional locks are used, then the screen can be locked, but the structure is complex and requires multiple components like blocks and grooves
Solution Approach 1:
The patent merges the block and groove components into a single integrated lock seat structure. The through hole and groove are formed directly in the lock seat, eliminating the need for separate block and groove components and simplifying the overall structure while maintaining the locking function
Solution Approach 2:
The lock seat serves multiple functions: it provides the through hole for the lock core, contains the groove for pin movement, and integrates the locking and guiding functions that were previously distributed across multiple components, reducing structural complexity

AI summary
An LED display screen lock includes a handle, a lock seat and a lock core. The lock seat includes a base, a through hole and a pin slidably disposed on the base. The lock core is rotatably disposed on the handle and received in the through hole. A locking hole is formed on the lock core and the pin is inserted in the locking hole. An unlocking portion is disposed on a circumference of the handle. The unlocking portion is abutted against the pin, in order to drive the pin to exit the locking hole.
