A damper pivot, also known as a pivot shaft, is an essential component used to connect product parts that must withstand both bending moments and torsional forces during operation. Damper pivots can achieve free rotation and positioning within a specific angle range, providing excellent damping characteristics. For example, when we open a laptop computer, the screen does not sway or drop, but rather remains stably positioned at the desired angle through the friction force within the pivot mechanism - this is the damping effect of the pivot.
The self-locking function is achieved by adding protrusions to the pivot shaft. When the pivot rotates past these protrusions, it produces a "click" sound, which is the self-locking function in action. For instance, when a laptop screen rotates to a specific angle, the computer will automatically close, demonstrating the self-locking function of laptop pivots. When designing the spacing of pivot self-locking points, it is recommended to set them at 90° intervals. If the intervals are too close together, the function will be difficult to perceive during rotation.
The limiting function is used to restrict the rotational angle of the pivot. For example, a one-piece damper pivot can typically rotate freely through 360°. However, if a customized requirement specifies only a 90° rotation range, a limiting mechanism must be added at the 90° position to precisely control the pivot's rotational range within 90° or less.
