Foldable Shooting Bracket Locking Structure Against Handle Shake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting brackets with auxiliary handles tend to rotate or shake when folded, compromising the stability and shooting effect due to relative rotation between the auxiliary handle and the main body.
Innovation Solution
A shooting bracket design featuring a connection device with a gear and connection rack system that locks the auxiliary handle in place when folded, preventing relative rotation and ensuring stability by meshing limiting parts, along with a snap-fit structure for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the auxiliary handle is folded on the bracket body for compact storage, then the portability is improved, but the auxiliary handle and bracket body are prone to rotation or shaking causing instability
Solution Approach 1:
The patent changes the state of the connection between auxiliary handle and bracket body from movable to fixed by engaging limiting parts. When folded, the connection transitions from a rotational degree of freedom to a locked position, changing the mechanical parameter of joint stiffness to eliminate shaking while maintaining compact folded size.
Solution Approach 2:
The patent introduces limiting parts (gear and connection rack) as intermediary elements between the auxiliary handle and bracket body. These intermediaries engage to prevent relative rotation when folded, acting as a mediator that maintains stability without preventing the folding action itself.
2Adaptability or versatility
If the auxiliary handle is made rotatable for flexible positioning during shooting, then the adaptability is improved, but the auxiliary handle becomes unstable when folded
Solution Approach 1:
The patent makes the connection dynamic by allowing it to switch between two states: locked (when folded) and rotatable (when unfolded). The limiting parts are designed to engage automatically when folded, providing stability, while allowing rotation when unfolded for flexible positioning during shooting operations.
Solution Approach 2:
The patent applies preliminary anti-action by pre-positioning the limiting parts to automatically engage and prevent rotation when the auxiliary handle is folded. This preemptive locking mechanism counteracts the potential instability before it can occur during storage or transport.
3Stability of the object's composition
If a locking mechanism is added to prevent rotation when folded, then the stability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the locking function with the existing rotational connection structure. The limiting parts (gear and connection rack) are integrated into the joint between auxiliary handle and bracket body, combining the positioning and locking functions into a single integrated mechanism rather than adding a separate locking device.
Solution Approach 2:
The locking mechanism is designed to be self-activating based on the folded state. When the auxiliary handle is folded, the limiting parts automatically engage through the meshing of gear and connection rack without requiring external actuation, making the system self-servicing and minimizing additional complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively locks the auxiliary handle in a stable position, preventing rotation or shaking, thereby enhancing the use stability and shooting effect of the equipment by maintaining a stable connection device state.
Implementation Method 1
a gear is provided on the top of the bracket body to form the first limiting part; a connection rack that matches the gear is provided at a position of the auxiliary handle near the hinged end to form the second limiting part; when the auxiliary handle is in a folded state, the auxiliary handle is locked on the bracket body through the mutual meshing between the connection rack and the gear

AI summary
The present application belongs to the technical field of shooting auxiliary equipment and relates to a shooting bracket, which includes a bracket body, a connection device, a clamping device and an auxiliary handle with a hinged end. The connection device is mounted on the bracket body. One of the bracket body and the auxiliary handle is provided with a first limiting part, and the other is provided with a second limiting part matched the first limiting part. When the auxiliary handle is in the folded state, through meshing the first limiting part and the second limiting part, relative rotation between the auxiliary handle and the bracket body is prevented. The shooting bracket is provided with a first limiting part and a second limiting part that is meshed with each other to limit rotation of the clamping device connected to the connection device.
