Product Description
Hex Socket Base Ball Plunger
●Product Overview
The spring-less hex socket base ball plunger is an innovative positioning component that operates on a mechanical adjustment principle. It completely eliminates the failure-prone spring mechanism found in traditional ball plungers, replacing it with a precision hex-driven screw-cam (or wedge) mechanism that directly controls ball protrusion.
This design enables infinitely variable and precisely adjustable positioning force while providing a mechanically self-locking holding capability. By turning a hex key, users can lock the ball at any position within its travel range, fundamentally solving the pressure decay issues associated with spring fatigue. This makes it particularly suitable for applications demanding long-term stability and extreme reliability.
●Key Features
Precise Positioning:
The most common function. It ensures two components (e.g., covers, doors, jigs, index plates) align accurately at pre-defined points during closure or movement. The ball engages with a corresponding detent (recessed hole) on the mating part, providing secure and repeatable physical registration.
Limiting & Locking:
Prevents unintended sliding or movement of components. It is often used in drawers, linear slides, and adjustable brackets to provide a defined holding force, preventing accidental disengagement.
Tactile & Audible Feedback:
As the ball snaps into or out of a detent, it produces a clear "click" sensation and sound. This provides unambiguous operational confirmation to the user, significantly enhancing the human-machine interface and overall user experience of a device. Common in joysticks, knobs, and folding mechanisms.
Torque Limitation & Overload Protection:
In drive or linkage mechanisms, the spring force of the plunger can be set to a specific "slip" threshold. If the torque or force exceeds this set value, the ball will disengage from the detent, thereby protecting more sensitive components from damage.
