The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 shows the automatically reset overall structure of a kind of embodiment of door hinge of the utility model.This door hinge system comprises following three parts: the first side wall 5, second sidewall 6 and base 7.
One " V " shape track 1 is set on second sidewall 6 of the door hinge that automatically resets, and the end, omited in the upper surface of base 7 in the bottom 4 of " V " shape track 1, and be in base 7 centers." V " shape track 1 is a symmetrical structure, is in 4 centers, bottom of " V " shape track 1 when door leaf is in closed condition; The two ends of " V " shape track 1 are connected with the first side wall 5, and these two ends all are higher than the upper surface of base 7, the surface of " V " shape track 1 preferentially is set to plane or level and smooth curved surface, and the plane that " V " shape track 1 forms becomes 10 degree～45 degree angle of slope with the plane that base 7 forms.Being provided with like this is beneficial to the running roller parts lifting moving in orbit that is arranged on the door that automatically resets.
A through hole 2 is established in automatically reset base 7 centers of door hinge, and this through hole 2 is used to the door-hinge of packing into, and door-hinge can freely rotate in through hole 2, and door-hinge can be fixed a door leaf perpendicular to the plane at base 7 places of door hinge system by this door-hinge.In addition, by running roller parts door-hinge, door leaf and " V " shape track 1 are linked to each other, when door leaf is in closed condition, the running roller parts are positioned at the center of the bottom 4 of " V " type track 1, when door leaf was subjected to external thrust, door leaf rose on " V " type track 1 by the wheel of running roller parts, when external force disappears, because the gravity of door leaf self, door leaf is got back to the center of the bottom 4 of " V " type track 1 again by the wheel of running roller parts.Whereby, can automatically reset after door leaf is opened.Because the both sides of " V " type track 1 are symmetrical, so the running roller parts can roll on the both sides of " V " type track 1, and then door leaf can bidirectional open.Thereby door leaf is free to bidirectional open and realizes automatically reseting.Certainly, the door hinge that automatically resets can be made different changes, thereby the angle that the change door leaf is opened satisfies different needs.
An opening 3 is set on the first side wall 5 of the door hinge that automatically resets at least, and be used to pack into nail or screw are with the door hinge that fixedly automatically resets.In the present embodiment, preferably the number with opening 3 is made as four, makes the fixed effect of the door hinge that automatically resets better.
Fig. 4 shows the automatically reset side-looking structure of a kind of embodiment of door hinge of the utility model, and as can be seen from the figure, the two ends that " V " shape track 1 links to each other with the first side wall 5 are provided with holddown groove 8, and holddown groove 8 is used for fixing the door that automatically resets.Under external force, the wheel of running roller parts rises along " V " shape track 1, causes the door that automatically resets can open certain angle, if external force loses, the gravity of a dependence itself of then automatically reseting is got back to V " center of the bottom 4 of type track 1, the door that automatically resets is closed; If external force exists, the wheel of running roller parts rises and falls into holddown groove 8 along " V " shape track 1, and at this moment, external force disappears, and then the wheel of the running roller parts groove 8 that is fixed blocks, and causes the door that automatically resets not automatically reset.Whereby, holddown groove 8 has reached the effect of the door that fixedly automatically resets, and the door that automatically resets just can stay open state.Certainly, under external force, the wheel of running roller parts also can roll out holddown groove 8, the automatically reseting of the door of realizing then automatically reseting.
Fig. 5 is the automatically reset structural representation of another embodiment of door hinge of the utility model.The door hinge that automatically resets is provided with " V " shape track 51, cylinder 52, base 53, fixed bit hole 54, sidewall 55 and guard circle 56.
" V " shape track 51 is a symmetrical structure, and the two ends of " V " shape track 51 are connected with sidewall 55, and the orbital plane from the bottom of " V " shape track 51 to sidewall 55 is plane or level and smooth curved surface, this orbital plane be provided with the lifting moving that is beneficial to door leaf.
Cylinder 52 is connected perpendicular to base 53 and with base 53, simultaneously cylinder 52 also with vertical connection of bottom faces of " V " shape track 51, establish through hole in the cylinder 52, through hole is through to soffit from the upper surface of cylinder 52, be used to the door-hinge of packing into, and door-hinge can rotate freely in through hole.
A guard circle 56 is established at the top of sidewall 55, and the plane parallel at the plane at guard circle 56 places and base 53 places.When packing door-hinge into, make door-hinge pass guard circle 56 and then the through hole of the cylinder 52 of packing in.Whereby, guard circle 56 can make the fixed effect of door-hinge better, makes the door-hinge difficult drop-off.In use, door leaf is located at the top of guard circle 56, and is fixed on the door-hinge.By running roller parts " V " shape track 51 is linked to each other with door-hinge, when the switch door leaf, door leaf is done lifting moving with door-hinge, because the structure that " V " shape track 51 claims for both sides.Allowing door leaf be free to bidirectional open whereby also realizes automatically reseting.
Be provided with at least four fixed bit holes 54 on sidewall 55, can pack into nail or screw are used for fixing the door hinge that automatically resets.
Fig. 6 is the automatically reset structural representation of the another embodiment of door hinge of the utility model.As can be seen from the figure, " V " shape track 1 is a unsymmetric structure, uses such door hinge structure, and the door that automatically resets can be opened 90 degree left, opens 180 degree to the right, but door bidirectional open 270 degree that also promptly automatically reset.Present embodiment provides automatically reset door hinge since the shape of itself can be installed on the right angle doorframe.
Be more preferably, the door hinge that automatically resets that the utility model provides is cylinder iron or the PVC material, has guaranteed reliability of products and durability, has reduced maintenance cost.
In sum, the utility model is by being provided with one " V " shape track on the door hinge that automatically resets, and the two ends of described " V " shape track link to each other with described the first side wall, the bottom of " V " shape track is a little less than the upper surface of base, the surface of " V " shape track 1 is plane or level and smooth curved surface, and the plane that " V " shape track 1 forms becomes 10 degree～45 degree angle of slope with the plane that base 7 forms, the automatically reset base center of door hinge is provided with the fixing through hole of door-hinge, door-hinge can freely rotate in described through hole, can do lifting moving on described " V " shape track by the wheel of running roller parts after door leaf and door-hinge are fixing.Whereby, the utility model can make the free bidirectional open of door leaf and can automatically reset.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
