First angle be hinged, second angle of triangle pull-push piece and the housing hinge of hinge fixed arm, the of triangle pull-push piece
Long arc-shaped holes are provided at three angles, also set up L-type interlocking lever between hinge fixed arm and hinge rotary head, in the middle part of interlocking lever with
The housing hinge of hinge fixed arm, one end are hinged with hinge rotary head, and the other end then sets poke rod, and poke rod is inserted into triangle
In long arc-shaped holes at the third angle of shape pull-push piece.
It opens the door or at closing time, door-plate drives the rotation of hinge fixed arm, the rotation of hinge fixed arm pulls L-type interlocking lever to make
It is dynamic；It is inserted into due to the poke rod on L-type interlocking lever in the long arc-shaped holes at the third angle of triangle pull-push piece, poke rod is being transported
When moving to the end of long arc-shaped holes, triangle pull-push piece can be driven to rotate, so that compensator or trimmer pressure cylinder stretches, clamshell doors or pass
Door is acted into row buffering.
Since long arc-shaped holes take enclosed construction, the lower part stress surface increase of long arc-shaped holes is enabled, is not easy because opening energetically
Shutdown causes the lower part of long arc-shaped holes to be worn, and the door hinge for avoiding the abrasion of long arc-shaped holes and causing can not be in low-angle
Normal buffer capacity is provided in folding, thus the utility model causes door hinge while guarantee door hinge normal buffer capacity
Chain is more durable.Simultaneously as enclosed straight slot body construction of remaining silent just has position-limiting action to poke rod, because can prevent existing
Once having hinge rotary head and interlocking lever serious wear in technology, can not continue to limit poke rod so that poke rod can
The problem of being skidded off from open slot, and door hinge is caused to be fallen apart, security risk is eliminated, extend door hinge uses the longevity
Life.

Specific embodiment
A kind of door hinge structure turns including hinge fixed arm, hinge rotary head 13 and connects hinge fixed arm and hinge
The connection neck of dynamic head, connection neck both ends are hinged respectively with hinge rotary head and hinge fixed arm, in the housing of hinge fixed arm
There is telescopic compensator or trimmer pressure cylinder 14 in portion, and one end of pressure cylinder and the housing hinge of hinge fixed arm, the other end are pushed away with triangle
First angle of draw piece 11 is hinged, second angle of triangle pull-push piece and the housing hinge of hinge fixed arm, triangle push-and-pull
Long arc-shaped holes 201 are provided at the third angle of part, L-type interlocking lever 12 is also set up between hinge fixed arm and hinge rotary head,
It is hinged in the middle part of interlocking lever with the housing hinge of hinge fixed arm, one end with hinge rotary head, the other end then sets poke rod
102, poke rod is inserted into the long arc-shaped holes at the third angle of triangle pull-push piece.
It is noted that the pressure cylinder is pneumatic cylinder or hydraulic cylinder.
During enabling, door-plate guiding door hinge start, hinge fixed arm rotates clockwise, and interlocking lever is pulled by hinge fixed arm
Carry out counterclockwise movement；And drive the arcuately slot hole movement from top to bottom of poke rod 102；Poke rod 102 is from top to bottom arcuately
Slot hole moves so that triangle pull-push piece 11 rotates counterclockwise, and is drawn outside piston rod so as to drive.At closing time, hinge fixed arm, gearing
Bar, the rotation of 11 negative direction of triangle pull-push piece, arcuately slot hole moves poke rod 102 from the bottom to top, so as to be pushed into piston rod, to closing
Door this act into row buffering.
Since long arc-shaped holes 201 take seal type structure, the lower part stress surface increase for straight slot of remaining silent is enabled, is not easy because energetically
Switch gate causes the slot bottom of long arc-shaped holes to wear, and influences the movement locus of poke rod, so as to influence the buffering effect of door hinge.And
And the long arc-shaped holes of enclosed construction preferably limit poke rod, solving poke rod in the prior art may skid off
The hidden danger of open slot, and increase the service life of door hinge.
Further, due to long arc-shaped holes, its slot bottom inherently can generate position-limiting action to poke rod, i.e., need not pass through hinge
Chain rotary head offsets to limit poke rod with interlocking lever, so under the left upper part of hinge rotary head and the right end of interlocking lever
Portion can not offset in the process of rotation, while ensureing to have limit function to poke rod, eliminate hinge rotary head with interlocking
Bar offsets and causes the rigidity abrasion between two components, makes door hinge more robust.
It should be pointed out that since the opening slot structure of existing door hinge does not have poke rod position-limiting action, existing door hinge is
It relies on the left upper part of hinge rotary head and the right end lower part of interlocking lever offsets to limit continuing to move to for poke rod.It is opening the door
Before, angle between hinge rotary head and hinge fixed arm is 90 degree, during Men Kaizhi maximum angles, hinge rotary head and hinge
Angle between fixed arm theoretically should be 180 degree.However, the left upper part of hinge rotary head and the right end lower part phase of interlocking lever
To when, hinge rotary head and hinge fixed arm can be more than 180 degree, i.e., door can be caused to generate collision with wall when opening the door, repeatedly
Striking mark can be left in wall after shock, very influenced beautiful.And the utility model carries out poke rod using long arc-shaped holes
Limiting, the motion track of poke rod are limited by the shape of long arc-shaped holes, the angle between hinge rotary head and hinge fixed arm
When spending for 180 degree, poke rod is moved to the lower end of long arc-shaped holes and stops to stop by long arc-shaped holes lower edge just
Movement, makes hinge rotary head also stop operating therewith, and angle will not between hinge rotary head and hinge fixed arm during so as to open the door
More than 180 degree, it is therefore prevented that door-plate is collided with wall during enabling.
