Fig. 3 is the combine schematic diagram of following hinge hinge pillar with the lower support hole.

The specific embodiment:

Below in conjunction with accompanying drawing the specific embodiment is elaborated: special-purpose center hinge of a kind of washroom partition door and automatic revolving gear, include: by the upper hinge of 2 one-tenth of upper support element 1 and door top mounting subassembly groups, the following hinge of forming by lower support 4 and student's fixation kit 5.

Fig. 1 has provided the utility model embodiment upper hinge structural representation.Among the figure, upper hinge door top mounting subassembly 2 is by cylindrical shell 22 and be fixed on the last stator 23 of cylindrical shell top, hinge 24, spring 25, ring washer 26 is formed, described hinge 24 is stepped cylinder, the big end of hinge is positioned at cylindrical shell, the hinge small end is stretched in outside the cylindrical shell outward, ring washer 26 is installed in the groove of nearly cylindrical shell 22 ports, spring 25 is between hinge 24 big ends and ring washer 25, described upper support element is is inverted the L horn shape, upper support element 1 horizontal segment 11 is provided with for the rotating axis hole 12 of hinge axle head, described upper support element 1 vertical section is fixed on the doorframe column sidewall, horizontal segment is fixed on lintel on the doorframe, the cylindrical shell 22 of top mounting subassembly 21 is embedded in the upper side frame of door leaf, and last stator 23 is fixed on the door leaf upper side frame, and hinge 24 axle heads of top mounting subassembly insert in the axis hole 12 of upper support element 1 horizontal segment 11.Described upper support element horizontal segment is provided with for the rotating axis hole of hinge axle head can also take following measure: be provided with borehole jack 13 within it, the outer rim of borehole jack is rectangular to be embedded in the rectangle hole slot of upper support element 1 horizontal segment, the endoporus of borehole jack 13 and hinge axle 24 necks match, hinge 24 axle heads of top mounting subassembly insert in the axis hole 12 of upper support element 1 horizontal segment, fix by plain washer 14, screw 15, borehole jack 13 is installed in the axis hole 12, can avoids the wearing and tearing of axis hole 12.

Fig. 2 is a hinge arrangement schematic diagram under the utility model embodiment.Among the figure: under the following hinged door fixation kit 5 by following stator 51 and with the hinge cover 52 of its one, hinge 53 is formed, institute's hinge 53 is made up of the screwed hinge body 55 of lining body 54 that has inclined contact surface 56 and end, described inclined contact surface 56 is the helicoid that a subtend axle center of symmetry tilts, described hinge cover 52 contains and serves as a contrast the helicoid that a subtend axle center that body 54 inclined contact surfaces match tilts, described lower support 4 L-shaped horn shapes, lower support 4 horizontal segments 41 are provided with the hole 42 for 55 break-through of hinge body, described lower support 4 vertical sections are fixed on the doorframe column sidewall, the hinge cover 52 of following fixation kit is embedded in the door leaf lower frame, following stator 51 is fixed on the door leaf lower frame, and hinge body 55 axle heads of following fixation kit 5 are fixed on lower support 4 horizontal segments 41 by nut 57; The utility model has also been taked following measure: described hinge hinge body 55 is down supplying 42 joint portions, hole of hinge body break-through to be provided with plurality of teeth 58 with lower support 4, lower support 1 is provided with the teeth groove that is meshed with plurality of teeth 58 for hole 42 inner edges of hinge body 55 break-through, as shown in Figure 3.When the line of symmetry of the helicoid that tilts of the lining body one subtend axle center of hinge and lower support horizontal segment are same direction instantly, the open degree of door is zero, when the hinge body of hinge turns over a tooth position with respect to the lower support horizontal segment under every adjusting, the line of symmetry of the helicoid that one subtend axle center of lining body tilts just turns over an angle, the opening angle that also is door leaf has been done adjustment, and the user can make adjustment as required.

The cylindrical shell axial line of upper hinge of the present utility model overlaps axial line on same vertical line with following hinge hinge, also is that upper and lower hinge rotates around same axial line.The utility model is work like this: behind the home position of adjusting door leaf, push the door open the hinge cover inclined contact surface of hinge at present along the slippage that makes progress of the inclined contact surface of hinge bush down, this moment door rotates its center of gravity thereupon and also moves on the helix with inclined contact surface, and the spring force that overcomes upper hinge compresses spring, the aperture of door is big more, and the center of gravity of door leaf rises high more; After external force was eliminated, door leaf was because of action of gravity, and with the inclined contact surface downslide of hinge hinge lining down, door leaf returns back to the home position.

The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
