Camera Quick Locking Chuck for Fast Release Plate Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera clamp holders require repeated screwing of knobs for locking, resulting in cumbersome operation and slow movement of movable chucks, leading to low efficiency in locking and unlocking.
Innovation Solution
A quick locking device with a triggering member that shifts a driving body to move the movable chuck away from or close to a fixed chuck for clamping, using a locking head to secure the chuck in place, allowing for rapid locking and unlocking by rotating the triggering member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If knob push-type locking is used, then the structure is simple and reliable, but repeated screwing is required resulting in cumbersome operation and low efficiency
Solution Approach 1:
The patent transforms the static knob-screwing mechanism into a dynamic lever-based system. The lever can be quickly rotated to switch between locked and unlocked states without repeated screwing motions. This dynamic mechanism allows the clamp holder to rapidly transition between states, significantly reducing locking time while maintaining reliability.
Solution Approach 2:
The patent replaces the traditional screw-threaded mechanical connection with a lever-based mechanical advantage system. Instead of relying on repeated rotational screwing of knobs, the lever uses rotational motion to directly drive the movable chuck, eliminating the need for multiple screwing cycles and thereby reducing operational complexity and time.
2Speed
If movable chucks are driven by screwing knobs, then the locking mechanism is reliable, but the movable chucks move slowly resulting in low efficiency
Solution Approach 1:
The lever mechanism introduces dynamic motion to drive the movable chuck. When the lever is rotated, it creates a rapid back-and-forth motion that quickly moves the movable chuck between locked and unlocked positions. This dynamic drive significantly increases the speed of chuck movement compared to the slow, incremental motion produced by screwing knobs.
Solution Approach 2:
The patent segments the locking mechanism into distinct functional components: the lever as the driving element, the driving body as the transmission element, and the movable chuck as the executing element. This segmentation allows each component to be optimized for its specific function, with the lever providing rapid motion and the driving body efficiently transmitting this motion to the chuck, thereby improving overall movement speed and locking efficiency.
3Reliability
If repeated screwing of knobs is required, then the locking is stable, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent substitutes the complex repeated screwing operation with a simple lever rotation mechanism. The lever, when rotated, directly engages the driving body to move the movable chuck into the locked position. This single rotational action replaces multiple screwing cycles, reducing operational complexity while maintaining locking stability through the secure engagement of the movable chuck with the fixed chuck.
Solution Approach 2:
The lever mechanism incorporates a self-locking feature where the position of the lever itself provides the locking action. When rotated to the locked position, the lever's geometry ensures that the movable chuck is firmly engaged with the fixed chuck. The system serves itself by using the lever's own motion and position to achieve both the locking action and the stability, eliminating the need for additional securing steps or complex operations.

AI summary
The present disclosure relates to the technical field of auxiliary photography equipment, and specifically to a quick locking device and a photography kit. The quick locking device comprises a base, a housing, a fixed chuck, a movable chuck, a driving body, a triggering member, and a locking head. The triggering member shifts the driving body to drive the movable chuck to get away from the fixed chuck when rotating, and then a camera quick release plate can be installed into a dovetail groove formed by the two chucks. After the installation is completed, the triggering member is automatically reset, and when rotating to be reset, the triggering member shifts the driving body to drive the movable chuck to quickly get close to the fixed chuck to clamp the camera quick release plate.
