Rotating Pin Lock Connection for Fast Lifting Beam Splicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting beam splicing technologies are inconvenient and inefficient, particularly for large LED displays that require frequent splicing and transportation, where the length of lifting beams needs to match the size of the boxes for secure fastening and lifting.
Innovation Solution
A pin-type connection apparatus comprising a first connecting seat, a second connecting seat, a connecting shaft, and a locking component with clamping protrusions and a locking mechanism that allows for easy alignment and secure locking of the connecting shaft between the seats, facilitating efficient splicing and assembly by manual operation.

Engineering Contradiction Analysis
1Productivity
If traditional lifting beam splicing methods are used, then the lifting beams can be connected, but the splicing process is inconvenient and inefficient
Solution Approach 1:
The lifting beam is divided into multiple sections with connecting seats that can be spliced together. Each connecting seat has a receiving hole and locking hole, allowing modular assembly. The connecting shaft with clamping protrusions enables segmented beams to be joined efficiently while maintaining overall structural integrity.
Solution Approach 2:
The locking component features a rotation shaft with clamping protrusions that automatically engage with the connecting shaft through a locking mechanism. When the rotation shaft is rotated, the clamping protrusions automatically lock into place, eliminating the need for additional fastening operations and enabling self-locking connection.
2Reliability
If the locking component is designed with multiple clamping protrusions and locking holes, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The connecting shaft serves multiple functions: it provides structural connection between lifting beam sections, guides the locking component through its receiving hole, and engages with clamping protrusions for secure locking. The rotation shaft similarly serves as both a locking mechanism and a guide for the clamping protrusions, reducing the need for separate dedicated components.
Solution Approach 2:
The locking component is nested within the connecting shaft structure. The rotation shaft passes through the receiving hole of the connecting seat, and the clamping protrusions are positioned within the connecting shaft, creating a compact nested arrangement that reduces overall complexity while maintaining reliability.
