The objective of the invention is to be achieved through the following technical solutions: comprise housing, fixed axis, sliding spool, return spring, wherein, sequence unit has sliding spool, return spring, pressure adjustment screw in housing; It is characterized in that: hull outside is provided with external axle housing, and fixed axis is installed in the external axle housing; Connector one end and fixed axis are hinged, and the other end of connector is connected with sliding spool.
Described offset hinge mechanism is characterized in that: connector one end is an axis hole, is provided with double wedge in the axis hole, and the fixed axis surface is that helical groove structure and double wedge engagement constitute sliding spiral pair.
Described offset hinge mechanism is characterized in that: at connector one end is axis hole, be provided with in the axis hole with fixed axis on the corresponding helicla flute of helicla flute, steel ball is embedded in and constitutes rolling screw pair in the helicla flute.
Described offset hinge mechanism is characterized in that: connector one end is provided with Rolling bearing, and fixed axis is provided with helicoid, and Rolling bearing and helicoid constitute the rolling screw friction pair.
Described offset hinge mechanism, it is characterized in that: the sliding spool cunning is contained in the housing, and damper piston is installed in the sliding spool inner chamber, has oilhole on the damper piston, form the grease chamber that seals by seal cover, spindle, sealing ring, inside, grease chamber is full of damping oil.
The present invention is when installing and using, whole housing is installed in the stile frame of door leaf, affixed by support arm and door leaf bottom frame, external axle housing is fixed on the outside (this example is the split external) of the frame of door leaf bottom with screw, the lower end of fixed axis is inserted in the doorframe installing hole fixing, in the locating hole of upper end removable mounting in external axle housing, housing and stile frame under external force, external axle housing is that rotate along a certain direction at the center together with the fixed axis, hinged inevitable the rotation along the helicla flute on the fixed axis of an end of connector and fixed axis risen, under the drive of connector, the other end just promotes sliding spool and moves axially, the revolving force that external force is acted on the door leaf changes over axial force, compression retracteding position spring, convert the pressure energy of return spring to, stored energy, till the opening position of setting (this example is a free type), at closing time under the effect of return spring release pressure energy, return spring promotes sliding spool and axially resets, by connector with return spring pressure can active force be decomposed into turning effort power along the fixed axis circumferencial direction, drive door leaf oppositely rotation automatically of helicla flute on fixed axis by connector, until door is closed.
Good effect of the present invention is: hull outside increases external axle housing, make fixed axis and sliding spool form the mechanism that be arranged in parallel by connector, realized the biasing of fixed axis and housing axle center, whole housing is hidden in the built-in stile frame that is installed in door leaf, does not have to prop up very long rod member outward, and outward appearance does not have the installation screw, simple in structure, safe, durable, attractive in appearance, embody than the unrivaled advance of prior art, have vast market prospect and social benefit.
