Transport Cart Connecting Structure for Stable Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable transport carts lack stability and require significant effort to operate, leading to deformation and reduced efficiency during use.
Innovation Solution
A connecting structure comprising fixing components, a connecting shaft, a connecting sleeve, pull rings, and locking portions that allow for stable connection and easy assembly/disassembly of the transport cart, enabling flexible operation and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If foldable transport carts are used for convenient storage, then storage space is reduced, but structural stability deteriorates causing deformation during use
Solution Approach 1:
The transport cart employs a dynamic folding mechanism where the connecting shaft and connecting sleeve allow the cart to transition between extended (stable for use) and contracted (compact for storage) states. The locking portion provides dynamic stabilization by locking the structure in the extended position during use, preventing deformation while maintaining foldability for storage.
2Ease of manufacture
If foldable transport carts are used for compact storage, then storage efficiency is improved, but operational reliability deteriorates due to lack of robust structure
Solution Approach 1:
The transport cart is segmented into multiple components (connecting shaft, connecting sleeve, locking portion) that can be independently positioned and locked. This segmentation allows the cart to maintain a robust, stable structure during use through proper locking, while still enabling compact folding for storage by disengaging the locking mechanism.
3Adaptability or versatility
If transport carts are frequently switched between states, then operational flexibility is improved, but operator effort increases reducing work efficiency
Solution Approach 1:
The locking portion is designed to automatically engage with the fixing component when the connecting sleeve is in the correct position, reducing the need for manual intervention. The elastic member provides self-locking functionality, allowing the cart to maintain its state without continuous operator input, thus reducing effort during frequent state transitions while preserving operational flexibility.

AI summary
Disclosed is a connecting structure, including: fixing components, a connecting shaft that is connected to the fixing components, a connecting sleeve that is sleeved on the connecting shaft, and pull rings and locking portions spaced apart from the pull rings on the connecting sleeve, where the pull rings are arranged around the connecting sleeve, and the pull rings extend along one side of the connecting sleeve away from the connecting shaft; the locking portion penetrates through the fixing component; the connecting sleeve and the connecting shaft are arranged in a relatively movable manner, so that the locking portion has a locked state of protruding from the fixing component and a contracted state of contracting inside the fixing component; and when the locking portion is in the locked state, the locking portion is connected to a to-be-connected component, so that the connecting structure is fixedly connected to the to-be-connected component.
