Detentlås

Detentlås is a type of locking mechanism commonly found in tools and mechanical devices. It utilizes a detent, which is a small pin or rod, to engage with a corresponding notch or recess. This engagement prevents unwanted movement or disengagement of parts. When a specific action or force is applied, the detent is moved out of its locked position, allowing the mechanism to operate.

The principle behind a detent lock is relatively simple. A spring-loaded detent is typically used, meaning it is held in its engaged position by a spring. To disengage it, an external force is required to overcome the spring tension. This force can be applied manually, for example, by pressing a button or lever, or it can be triggered by another part of the mechanism. Once the detent is disengaged, the parts it was securing are free to move.

Detent locks are valued for their reliability and simplicity. They are often used in applications where a secure but easily releasable lock is needed. Examples include the locking mechanisms in retractable ballpoint pens, where a click action engages and disengages the tip, or in certain types of firearms to hold components in place. They can also be found in various industrial equipment, where they ensure that adjustable parts remain in their set positions until intentionally changed. The robustness of detent locks makes them suitable for environments with vibration or impact.
