Rotary Central Lock Structure for Stable Foldable Tent Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing foldable tent locking mechanisms, particularly those using a button-type unlocking structure, are complex, affecting the overall appearance and exhibit poor unlocking stability.
Innovation Solution
A rotary unlocking central lock device is designed for foldable tents, featuring a lock rod latch mechanism with a latch plate and lock rod engaging groove, where the rotary base's rotation allows for locking and unlocking, and position-limiting pillars and arc-shaped grooves ensure secure alignment without external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a button-type unlocking structure is adopted for the locking mechanism, then the locking function can be achieved, but the structure becomes complicated and the appearance is affected
Solution Approach 1:
The patent extracts and eliminates the button component from the locking mechanism. Instead of using a button-type unlocking structure with additional components, the invention employs a direct rotary base rotation mechanism that achieves locking and unlocking through the rotational movement itself, removing unnecessary elements and simplifying the overall structure.
Solution Approach 2:
The patent inverts the conventional button-press unlocking approach by using a rotary motion mechanism. Instead of pressing a button to trigger unlocking, the user rotates the rotary base to directly engage or disengage the lock rod with the latch mechanism, fundamentally changing the interaction mode from linear pressing to rotational movement.
2Reliability
If additional components like pressing buttons are required, then the locking mechanism can operate, but the manufacturing cost increases
Solution Approach 1:
The patent merges the unlocking function directly into the rotary base structure itself. The rotary base integrates the locking mechanism control, eliminating the need for separate button components, springs, and associated assembly steps. This consolidation reduces the number of parts, simplifies manufacturing, and lowers production costs while maintaining reliable locking functionality.

AI summary
A rotary unlocking central lock device is adapted for a foldable tent. The rotary unlocking central lock device includes a top plate base, a lock rod, a lower plate base, and a rotary base. The rotary base is rotatably fit with the lower plate base. A lock rod latch mechanism is disposed between the rotary base and the lower plate base. A top portion of the lock rod is fixed with the top plate base. A bottom portion of the lock rod penetrates through the lower plate base to fit with the lock rod latch mechanism. Locking and unlocking of the lock rod and the lock rod latch mechanism can be realized by rotation of the rotary base.
