Abstract

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.

First claim

What is claimed is:

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.

2. The pivot pin device as claimed in claim 1 , wherein the first component is a board body structure, the first component having an extension section protruding from the first component, a fixing hole being formed on the extension section for fixing a head end of the fixing shaft, the second component being a board body structure, the second component having an extension section protruding from the second component, the slot being formed on the extension section of the second component, the seat section including two stopper walls and a cavity positioned between the two stopper walls, the seat section being locally formed with a connection section for connecting the two stopper walls, the rocking arm being disposed in the cavity between the two stopper walls.

3. The pivot pin device as claimed in claim 2 , wherein the stopper walls are disc-shaped, the stopper walls having a width larger than a diameter of the fixing shaft, the two stopper walls being respectively formed with notches in radial direction of the fixing shaft for assembling with the eccentric shaft, the rocking arm including a connection section connected between the first and second head ends, a cross-sectional area of the first and second head ends being larger than a cross-sectional area of the connection section, whereby a dented section is formed between the first and second head ends, the first head end being formed with an assembling hole for pivotally connecting with the eccentric shaft, whereby the rocking arm is permitted to swing.

4. The pivot pin device as claimed in claim 3 , wherein the fixing shaft is formed with a recess corresponding to the notches of the two stopper walls, the recess communicating with the notches of the two stopper walls to together form a space for assembling the eccentric shaft therein, the first head end of the rocking arm and the eccentric shaft being arranged in the cavity of the seat section, the eccentric shaft being fixedly mounted in the notches of the two stopper walls of the seat section and the recess of the fixing shaft, the second head end of the rocking arm being permitted to swing with the eccentric shaft as a fulcrum.

5. The pivot pin device as claimed in claim 1 , wherein a fixing disc is disposed on the fixing shaft in a position in adjacency to the seat section, the fixing disc having a shaft hole and an eccentric hole in communication with the shaft hole, a part of the shaft hole of the fixing disc communicating with a part of the eccentric hole to together form a geometrical hole substantially in the form of a calabash, a head end of the eccentric shaft being pivotally connected in the eccentric hole.

6. The pivot pin device as claimed in claim 2 , wherein a fixing disc is disposed on the fixing shaft in a position in adjacency to the seat section, the fixing disc having a shaft hole and an eccentric hole in communication with the shaft hole, a part of the shaft hole of the fixing disc communicating with a part of the eccentric hole to together form a geometrical hole substantially in the form of a calabash, a head end of the eccentric shaft being pivotally connected in the eccentric hole.

7. The pivot pin device as claimed in claim 3 , wherein a fixing disc is disposed on the fixing shaft in a position in adjacency to the seat section, the fixing disc having a shaft hole and an eccentric hole in communication with the shaft hole, a part of the shaft hole of the fixing disc communicating with a part of the eccentric hole to together form a geometrical hole substantially in the form of a calabash, a head end of the eccentric shaft being pivotally connected in the eccentric hole.

8. The pivot pin device as claimed in claim 4 , wherein a fixing disc is disposed on the fixing shaft in a position in adjacency to the seat section, the fixing disc having a shaft hole and an eccentric hole in communication with the shaft hole, a part of the shaft hole of the fixing disc communicating with a part of the eccentric hole to together form a geometrical hole substantially in the form of a calabash, a head end of the eccentric shaft being pivotally connected in the eccentric hole.

9. The pivot pin device as claimed in claim 1 , wherein the second head end of the rocking arm is formed with a pivot hole for pivotally connecting with the subsidiary shaft, the subsidiary shaft including a first section, a second section and a middle section connected between the first and second sections, a width of the middle section being larger than a width of the first section or the second section, the extension section of the second component being formed with a pivot hole for pivotally connecting with the second section of the subsidiary shaft, the first section of the subsidiary shaft being pivotally connected in the pivot hole of the rocking arm, the second section of the subsidiary section being assembled on the second component.

10. The pivot pin device as claimed in claim 2 , wherein the second head end of the rocking arm is formed with a pivot hole for pivotally connecting with the subsidiary shaft, the subsidiary shaft including a first section, a second section and a middle section connected between the first and second sections, a width of the middle section being larger than a width of the first section or the second section, the extension section of the second component being formed with a pivot hole for pivotally connecting with the second section of the subsidiary shaft, the first section of the subsidiary shaft being pivotally connected in the pivot hole of the rocking arm, the second section of the subsidiary section being assembled on the second component.

11. The pivot pin device as claimed in claim 3 , wherein the second head end of the rocking arm is formed with a pivot hole for pivotally connecting with the subsidiary shaft, the subsidiary shaft including a first section, a second section and a middle section connected between the first and second sections, a width of the middle section being larger than a width of the first section or the second section, the extension section of the second component being formed with a pivot hole for pivotally connecting with the second section of the subsidiary shaft, the first section of the subsidiary shaft being pivotally connected in the pivot hole of the rocking arm, the second section of the subsidiary section being assembled on the second component.

12. The pivot pin device as claimed in claim 4 , wherein the second head end of the rocking arm is formed with a pivot hole for pivotally connecting with the subsidiary shaft, the subsidiary shaft including a first section, a second section and a middle section connected between the first and second sections, a width of t
