Embodiment
With reference to accompanying drawing.Friction shaft hinge provided by the utility model, comprise rotating shaft 1 and be enclosed within the friction sleeve 2 outside rotating shaft 1, friction sleeve 2 and rotating shaft 1 utilize the frictional force between them to realize the function of freely stopping, and, can continue again to relatively rotate after overcome friction in input external force.
Described friction shaft hinge is provided with the rotating shaft initial rotation driving mechanism rotated together with rotating shaft 1 be enclosed within outside described rotating shaft 1, and described friction shaft hinge is also provided with the cam 3 and be enclosed within the outer clutch for clutch control cam 4 rotated together with rotating shaft of described rotating shaft 1 of sliding axially do not turned be enclosed within outside described rotating shaft 1, described friction shaft hinge is also provided with the conjunction 5 be enclosed within outside rotating shaft 1, conjunction 5 and friction sleeve 2 pass through location fit, the means such as to be fixedly connected with are rotated together, the described cam 3 that slides axially is driven by the clutch for clutch control cam 4 rotated and is combined to moving forward to it with conjunction 5 towards this side shaft of conjunction 5, conjunction 5 is not turned together with the cam 3 that slides axially, sliding axially described in ordering about, from initial bit, axially move forward to it is the operating angle of rotating shaft initial rotation driving mechanism with conjunction 5 in conjunction with required clutch for clutch control cam 4 rotation angle to cam 3, also the angle that the shaft hinge that namely rubs is opened automatically.Regulate the rotation angle needed for clutch for clutch control cam 4, i.e. the automatic open angle of adjustable friction shaft hinge.
The described cam 3 that slides axially can be groove and protruding combination with the combination of conjunction 5 also can be the combination of cam production, the location fit of step type etc.
The described cam 3 that slides axially drives the direction reset towards leaving conjunction 5 to slide by spring 6.Described spring 6 is in conjunction 5 and slides axially between cam 3.
