Description
Technical field
The present invention relates to a kind of door hinge.
Background technology
A kind of door hinge of existing door hinge, it comprises the fixture that can be fixed on the framework, can be fixed on the tumbler on the door-plate, first, second, third and fourth rotating shaft, the rotating shaft of " U " shape, connector, moving part, buffering hydraulically extensible bar, swing component and back-moving spring; Wherein said fixture comprises shell and is located at the inner casing of the installation usefulness in the shell, on shell and inner casing, is provided with the set screw that connects; Said connector one end is rotationally connected through first rotating shaft and shell, and the other end through the rotating shaft of " U " shape is rotationally connected with tumbler; One end of said moving part is fixed on the shell as rotating fulcrum through second rotating shaft, also is provided with pulling block at this end that connects moving part, and the other end is rotationally connected with tumbler through another axle of " U " shape rotating shaft; Said back-moving spring is arranged with in first rotating shaft; On tumbler, be provided with the groove of a ccontaining connector and moving part.
Said swing component is fixed on the shell as rotating fulcrum through the 4th rotating shaft, existing three kinds of the interlock mode of the other end of swing component and moving part.
First kind is crank-link mechanism, this kind mode be swing component with moving part between be connected through connecting rod, operating principle is: moving part rotates the swing of drivening rod pulling swing component, thus the piston rod of pulling buffering hydraulically extensible bar plays buffering.The complex structure of this mode, part is many, and it is difficult to install, and cost is high, and each part is to connect through three little rotating shafts, and driving error is big, and gearing friction power is big, and intensity is low.
Second kind of gear drive.This kind mode is that swing component and moving part mating part are processed into a pair of gear, and the operating principle of this mode is: moving part (driving gear) and swing component (driven gear) are to combine according to the principle of gear interlock.When rotating, moving part (driving gear) drives swing component (driven gear) to counter-rotation.Thereby the piston rod of pulling buffering hydraulically extensible bar plays buffering.The quality of fit of this mode requires high, and manufacture difficulty is big, and gearing friction power is big, and intensity is low, and cost is high.
The third is a Geneva mechanism.Moving part (sheave) is connected through rivet with swing component (dead man).When operating principle is moving part (sheave) rotation, drive swing component to opposite spin, thereby the piston rod of pulling buffering hydraulically extensible bar plays buffering through connecting rivet.The moving part of this mode is stacked by the multi-disc part to be formed, processed complex, and cost is high.This mode exists gearing friction power big equally, the problem that intensity is low.
Summary of the invention
The present invention overcomes the deficiency of prior art and a kind of brand new is provided, and this is simple and reasonable for structure, and intensity is high, and cost is low, and is easy for installation, a kind of door hinge that resistance is little during use, the life-span is long.
A kind of door hinge; Include by the interconnective tumbler of rotating shaft, fixture, transmission mechanism and buffering hydraulically extensible bar, described fixture comprises shell and inner casing, on shell and inner casing, is provided with the set screw that connects with displacement; Buffering hydraulically extensible bar is fixed in the inner casing; It is characterized in that: described transmission mechanism includes connector, moving part, back-moving spring and buffering pull-push piece, and connector one end is rotationally connected with tumbler, and the other end is rotationally connected with shell; Moving part one end is rotationally connected with tumbler; Moving part other end below is rotationally connected with shell; The buffering pull-push piece that buffering hydraulically extensible bar is fixed in moving part other end top and flexibly connects, and moving part is positioned at the below of connector, and described back-moving spring is installed in being connected in the rotating shaft of connector and shell; Back-moving spring one end is stressed to be fixed on the bearing of tumbler with it in connector, stressed being connected in the rotating shaft in moving part and shell of the other end.
Above-mentioned moving part is the driving member of an arc, and moving part one end has groove.
Above-mentioned buffering pull-push piece is a U-shaped piece spare, respectively is provided with a sliding recess or movable slotted eye on the U-shaped piece spare two side, and described sliding recess is positioned at the inboard, two side or the outside of U-shaped piece spare.
The groove two side of above-mentioned moving part is positioned at the buffering pull-push piece, forms inside and outside fit structure, and the outside, groove two side of moving part respectively is provided with and inboard sliding recess or corresponding cylinder boss or the rotating shaft of movable slotted eye of U-shaped piece spare two walls that cushion pull-push piece.
The groove two side of above-mentioned moving part is positioned at outside the buffering pull-push piece, form outer in fit structure, the groove two wall inboards of moving part respectively be provided with the U-shaped piece spare that cushions pull-push piece on the sliding recess or the corresponding cylinder boss or the rotating shaft of movable slotted eye in the two walls outside.
Respectively be provided with the arc boss to outer lug on the both sides of above-mentioned moving part, this arc boss is circular arc with buffering pull-push piece matching part.
Beneficial effect of the present invention
1, because buffering pull-push piece of the present invention and connector adopt sliding recess or movable slotted eye and cylindrical projection or rotating shaft, make of the present invention simple in structurely, to make simple and easyly, cost is low.In particular, compare with prior art, the transmission mechanism of existing technology needs connector; Moving part, connecting rod, spring and five drive disk assemblies of pulling block; And a plurality of parts are by there being the polylith sheet metal to combine, and transmission mechanism of the present invention only needs connector, moving part, back-moving spring and four drive disk assemblies of buffering pull-push piece, and drive disk assembly forms by a sheet metal stamped; Lowered manufacturing cost and simplified manufacturing technique greatly, simplified simultaneously and install.
2, owing to respectively be provided with the arc boss to outer lug on the both sides of moving part of the present invention, this arc boss is circular arc with buffering pull-push piece matching part, and frictional force is very little during use; Stable working, long service life, good buffer effect; Easy to manufacture, cost of production is low.
