Summary of the invention
Problem to be solved in the utility model is for the deficiency of above-mentioned technology, to design a kind of concealed type door hinge of automatic returning.
The utility model is that the technical scheme that its problem of solution adopts is:
A kind of concealed type door hinge of automatic returning, comprise concealed type door hinge main body, the right part of described concealed type door hinge main body is connected with a resetting means, left part or the right part of concealed type door hinge main body are connected with a snubber, described resetting means pull bar, be installed in the pull bar upper reset spring and be installed in adjusting nut on the pull bar, back-moving spring is set on the pull bar and between the outer wall and adjusting nut of concealed type door hinge main body.
In the utility model, described concealed type door hinge main body comprises one or above left-hand rotation arm, one or above right-hand rotation arm, be installed in the left holder on the door leaf and be installed in right holder on the doorframe, left and right pivoted arm from top to bottom interval is placed, the right-hand member of left-hand rotation arm is hinged in the right holder, its left end is movably connected in the chute I of left holder inside by bearing pin I, the left end of right-hand rotation arm is hinged in the left holder, its right-hand member is movably connected in the chute II of right holder inside by bearing pin II, and the middle part of left and right pivoted arm interconnects by through-shaft.
In the utility model, interconnect by a slide block between the left part of described left-hand rotation arm and the snubber, the left-hand rotation arm is connected with slide block by bearing pin I.
The beneficial effects of the utility model are: the utility model is connected with a resetting means in the right part of concealed type door hinge main body, when opening the door, this resetting means produces and has reasonable feel when pulling force opens the door the user, door can be closed by automatic returning under the effect of resetting means after opening, the convenient use.Further, the utility model is connected with a snubber in the left part of left-hand rotation arm, door is when automatic returning, for its soft and deceleration is resetted, by left-hand rotation arm, right-hand rotation arm, bearing pin I, II, through-shaft and slide block the recurrence power of resetting means being passed to damping oil cylinder slows down, reach damping, avoid door leaf moment closed and produce the huge sound and vibrations.The utility model has increased resetting means on the basis of traditional concealed type door hinge, but makes its automatic returning, and is too fast for preventing recurrence, increased damping buffer again, to reach cushioning effect, therefore has outstanding substantive distinguishing features and comparatively significantly progressive.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is the structural representation behind hiding left and right pivoted arm and the resetting means;
