Abstract
The present invention discloses a hinge structure with changeable frictional faces, comprising a spindle socketingly disposed with a first enclosing part and a second enclosing part with the openings of the first and second enclosing parts pointing to the same direction to change the frictional face for torsion from the second enclosing face to the first enclosing part and thus to extend the service life and further to form a frictional face with four steps of different torsions to meet the demands of customers.
Claims17
A hinge structure with changeable frictional faces, comprising:
- a spindle having a first end portion, a second end portion, and a stop portion;
- a first enclosing part socketingly disposed onto the first end portion of the spindle and having an opening and a protrusion;
- and
- a second enclosing part socketingly disposed onto the second end portion of the spindle and having an opening and a protrusion, the openings of the first and second enclosing parts pointing to the same direction;
- wherein when the second enclosing part rotates from its initial position to abut against the stop portion, the protrusion of the first enclosing part abuts against the stop portion and thus restrict the rotation of the spindle, and a low-torsion frictional face is formed by the rotation of the second enclosing part upon the second end;
- when the second enclosing part abutting against the stop portion rotates to α point, the protrusion of the second enclosing part pushes the stop portion and thus prompts the spindle to rotate jointly, and a high-torsion frictional face is formed by the rotation of the first end portion of the spindle within the first enclosing part;
- when the second enclosing part rotates from α point back to the stop portion, the second enclosing part holds tightly the second end portion of the spindle and thus prompt the spindle to rotate jointly, and a low-torsion frictional face is formed by the rotation of the first end portion of the spindle within the first enclosing part;
- when the second enclosing part rotates from the stop portion back to its initial position, the protrusion of the first enclosing part abuts against the stop portion of the spindle and thus restrict the rotation of the spindle, and a high-torsion frictional face is formed by the rotation of the second enclosing part upon the second end portion of the spindle.
