Tent Clamping Structure One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable tents have complex structures that are difficult to open and close efficiently, requiring two hands and lacking reliability in clamping mechanisms, especially when using springs for support.
Innovation Solution
A clamping and supporting structure featuring a tube piece, tube holder, handle, and locking sleeve with a spiral inclined surface and locking pins, allowing for one-handed operation by using a spring to guide the tube piece and handle for easy extension and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional snap-in device with expansion rod and clamping blocks is used, then the tent support can be clamped and supported, but the structure becomes complicated and difficult to operate with one hand
Solution Approach 1:
The patent extracts and removes the complex expansion rod and clamping block mechanisms from the conventional snap-in device. Instead, it uses a simple locking sleeve with a locking pin that can be operated with one hand, significantly simplifying the structure while maintaining the clamping and supporting function.
Solution Approach 2:
The patent inverts the conventional clamping mechanism by using a locking sleeve that rotates to engage or disengage a locking pin, rather than using expansion rods that push against clamping blocks. This inverted approach simplifies the operation to a single rotational motion that can be performed with one hand.
2Reliability
If a reset spring is used for clamping in the snap-in device, then the clamping function is provided, but the reliability is insufficient
Solution Approach 1:
The patent replaces the unreliable reset spring with a simple locking pin and locking sleeve mechanism that provides reliable clamping through mechanical engagement. The locking pin can be easily inserted and locked into place, providing dependable support without relying on spring fatigue.
3Reliability
If multiple components like tube piece, tube holder, handle, and locking sleeve are used, then the clamping and supporting function is improved, but the device complexity increases
Solution Approach 1:
The patent merges the functions of the tube piece, tube holder, handle, and locking sleeve into an integrated assembly where the locking sleeve rotates on the tube holder to control the tube piece extension. This merging reduces the number of separate operations needed while maintaining support stability.

AI summary
The utility model discloses a clamping and supporting structure of tent support, including a tube piece, a tube holder, and a handle arranged under the tube holder. The bottom of the tube piece passes through the tube holder and the handle and can extend oppositely. A locking sleeve is fixed with the tube holder and provides an inner wall of the locking sleeve is provided with a boss including a guide inclined surface is formed on a first side and ascends spirally from the bottom to the top. The tube piece is provided with a first locking pin and a second locking pin and can move opposite to the tube holder and the handle in the vertical direction and keep the trend of extending oppositely: the first locking pin is propped against the guiding inclined surface, and the second locking pin keeps the trend of propping against the stop piece.
