Background technology
Hinge, is the part for connecting the fixed components such as the movable parts such as door and window and doorframe.Hinge at least includes two panels tape spool
The blade of set and a hinge axis, to realize the function that connection, load-bearing and limitation blade only rotate around hinge axis.As the epoch are sent out
Exhibition, the type and function of hinge are gradually enriched, and its improvement direction is mainly：1. hinge opened/closed process, blade rotates flat
Surely, noiseless；2. close automatically/close door；3. buffering, door stop function.
For 1, solution is simpler, lastblock packing ring is added between two blades, then applied between axle sleeve and hinge axis
The larger lubricating oil of viscosity, it is desirable to which high can be changed to thrust ball bearing packing ring.
2 can solve simultaneously sometimes with 3, and closing a power mainly has spring pressure/torsion, the gravity of door, hydraulic coupling gentle
Four kinds of pressure.Spring hinge structure is simpler, but it closes a speed and continues to increase with an angle is closed, without buffering
In the case of final inertia impact at closing time it is larger, and spring restricted lifetime so that spring hinge is frequently necessary to debugging very
To replacing.The rising hinge that the gravity of door is closed the door is relied on, structure is simpler, only need to be script perpendicular to the axle sleeve port of hinge axis
The spiral form around hinge axis is changed to, hinge rotates along helical and rises during enabling, and back door of loosing one's grip forces hinge edge under gravity
Helical rotation declines and closes door.But rising hinge contact area of two hinge end faces when wide-angle is opened the door can be substantially reduced, because

The internal thread hole of conjunction, the circumferentially fixed connection of axle sleeve of the periphery wall of the piston and second blade, the packing ring is socketed in
In the middle part of hinge axis and positioned at the first blade top.
Further, the pitch of the screw thread of the multi start thread portion and internal thread hole is equal to the first blade or the second blade
Axle sleeve depth minus go the twice of the difference of the height of piston.
Further, the depth of the internal thread hole is highly consistent with the multi start thread portion.
Further, keyway, described hinge axis are provided with the first described blade, the inner hole of shaft sleeve of the second blade
The periphery wall of lower half and piston is provided with the flat key being engaged with corresponding keyway.
Further, the length of described keyway is the first blade, the half of the second blade sleeve length, width with it is described
