Pivot pin device

摘要

A pivot pin device provides a protection system. In operation/rotation, the pivot pin device achieves a height/position change effect. The pivot pin device includes a first component, a fixing shaft disposed on the first component and a second component assembled with the fixing shaft. The second component is formed with a slot for assembling with the fixing shaft. The fixing shaft is assembled with a rocking arm. A first head end of the rocking arm is pivotally connected with an eccentric shaft. A second head end of the rocking arm is pivotally connected with a subsidiary shaft assembled on the second component. When the slot of the second component is rotated around the fixing shaft to an opened position, the subsidiary shaft drives the rocking arm to swing with the eccentric shaft as a fulcrum, whereby a height/position change is achieved between the first and second components.

主权项

1. A pivot pin device comprising:
a first component, a fixing shaft being disposed on the first component; and a second component formed with a slot for assembling with the fixing shaft, the slot being defined with a first position and a second position, a seat section being disposed on the fixing shaft for assembling with a rocking arm, the rocking arm having a first head end and a second head end, the first head end being pivotally connected to the seat section with an eccentric shaft, the second head end being pivotally connected with a subsidiary shaft assembled on the second component, when the second component is rotated relative to the first component, the subsidiary shaft driving the rocking arm to swing with the eccentric shaft as a fulcrum, whereby the fixing shaft is relatively moved within the slot between the first and second positions to forma height difference between the first component and the second component with respect to a supporting base face.
