Tensioning Lock Mechanism for LED Display Screen Box Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation mode of existing LED display screen boxes is time-consuming and laborious due to the manual plugging and unplugging of tightly connected pin headers, which reduces efficiency.
Innovation Solution
A tension lock mechanism comprising a base, rotating shaft, shim, and knob, where the shim moves away from or towards the base upon knob rotation, facilitating the connection or disconnection of the rear cover to the box frame, allowing for easier assembly and disassembly by sliding along an axial direction, with an elastomeric bead enhancing the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional welding or screw fixing methods are used to connect the LED display screen to the supporting structure, then the connection strength is sufficient, but the installation process becomes complex and time-consuming
Solution Approach 1:
The connection system is segmented into distinct functional components: the supporting structure with integrated connection holes, the LED display screen modules, and the fastening mechanism using expandable bolts or wedge anchors. This segmentation allows each component to be optimized independently and assembled through simple insertion and expansion actions rather than complex welding or screw threading operations.
Solution Approach 2:
The supporting structure is pre-designed with connection holes and embedded anchor elements positioned at optimal locations. The LED display screen modules are pre-equipped with corresponding mounting features. This preliminary preparation eliminates the need for on-site drilling, welding, or complex alignment procedures during installation, significantly reducing installation time and complexity while maintaining strong connections.
2Strength
If traditional welding or screw fixing methods are used to connect the LED display screen to the supporting structure, then the connection strength is sufficient, but the installation time increases
Solution Approach 1:
The supporting structure is pre-designed with connection holes and embedded anchor elements positioned at optimal locations. The LED display screen modules are pre-equipped with corresponding mounting features. This preliminary preparation eliminates the need for on-site drilling, welding, or complex alignment procedures during installation, significantly reducing installation time and complexity while maintaining strong connections.
Solution Approach 2:
The installation process skips the time-consuming steps of welding, threading screws, or performing complex fastening operations. Instead, the expandable bolts or wedge anchors are simply inserted into the pre-prepared holes and expanded through a quick mechanical action, rapidly achieving secure connections without the prolonged procedures required by traditional methods.
3Stability of the object's composition
If the LED display screen is designed as a fixed rigid structure, then the structural stability is good, but the adaptability to different installation environments is reduced
Solution Approach 1:
The connection system incorporates dynamic elements that allow adjustment and adaptation. The expandable bolts can be inserted and expanded to different degrees to accommodate varying hole sizes and material densities. The supporting structure can be configured with connection holes at different positions and orientations to suit various installation environments such as walls, columns, or ceilings, while the LED display screen modules remain structurally stable through their rigid frame designs.
Solution Approach 2:
The connection system is designed with universal applicability across different installation scenarios. The same basic connection mechanism (expandable bolts or wedge anchors in pre-drilled holes) can be used for installing LED display screens on various supporting structures including concrete walls, steel columns, and wooden beams. This multi-functional connection approach eliminates the need for different fastening systems for different environments while maintaining structural stability.

Function Achieved in This Case
The tension lock significantly improves the installation efficiency of LED display screen boxes by allowing faster and more convenient assembly and disassembly, reducing the time and effort required for connecting and disconnecting components.
Implementation Method 1
an elastomeric bead mounted on the knob; and a first bead slot and a second bead slot arranged on one side surface of the shim facing the knob; when the knob is rotated to make the shim move away from the base, the elastomeric bead can slide from the first bead slot to the second bead slot

AI summary
The application belongs to the technical field of LED display screen box assembly, and relates to a tension lock and LED display screen box. The tension lock comprises a base, a rotating shaft, a shim and a knob, wherein the base is provided with a sliding hole, one end of the rotating shaft is fixedly connected with the knob, the other end of the rotating shaft is inserted into the sliding hole, the shim is rotationally connected with the rotating shaft, and the distance between the shim and the knob is kept constant; Turning the knob can make the rotating shaft rotate and slide along the axial direction of the sliding hole to make the shim move away from or close to the base. The tension lock can effectively improve the installation efficiency of LED display screen box.
