The purpose of this utility model is achieved in that

A kind of hinge is characterized in that it comprises upper hinge, following hinge, screens lid, spring;

One end of described upper hinge is provided with stationary axle, and the both sides that upper hinge is stretched out at the two ends of stationary axle form the stationary axle extending end;

Described end both sides of hinge down are provided with groove, and the stationary axle extending end of stationary axle is stuck in the groove;

Rotatable being fixed on down on the hinge of described screens lid is provided with the protrusion of closing groove in the inboard that screens covers.

Be with spring on the described stationary axle.

Aforesaid a kind of hinge is characterized in that the screens lid is " ∪ " shape, and the both sides inwall of the opening end of screens lid is provided with fulcrum, is being provided with the hole clipping that can snap in fulcrum on the hinge opposite position down.

Aforesaid a kind of hinge is characterized in that an end of spring is stuck in the upper hinge, and the other end is stuck in down in the hinge.

Aforesaid a kind of hinge is characterized in that upper hinge comprises decorative sheet and mounting plate, and following hinge comprises decorative sheet and mounting plate, mounting plate and on be provided with several fixed holes.

The utility model dismounting, easy for installation only need be opened the screens lid, and upper hinge is separated with following hinge, and do not need to dismantle other fastening piece, during installation, only need the stationary axle of upper hinge is inserted the groove of hinge down, rotate the screens lid again and close groove and get final product; Simple in structure, include only upper and lower hinge, screens lid and spring; Safety, screens are built the effect of safety protection, and upper and lower hinge can not broken away from after connection easily.

[embodiment]

A kind of hinge, it comprises upper hinge 1, following hinge 2, screens lid 3 is provided with stationary axle 4 at an end of upper hinge 1, and the both sides that upper hinge 1 is stretched out at the two ends of stationary axle 4 form stationary axle extending end 41; Be provided with groove 21 in following end both sides of hinge 2, the stationary axle extending end 41 of stationary axle 4 may be stuck in the groove 21, makes play hinge 2 support upper hinge 1, and can to make upper hinge 1 be that the center of circle rotates around following hinge 2 with stationary axle 4.The 3 rotatable upper ends that are fixed on down hinge 2 upper grooves 21 are covered in screens, and the inboard 311 on screens lid 3 is provided with the protrusion 31 of closing groove 21, and the edge of protrusion 31 is provided with the draw-in groove 32 that can snap in stationary axle 4, and rotation screens lid 3 just can open or close groove 21.When closing groove 21, protrusion 31 can be closed the outlet of groove 21, and stationary axle extending end 41 is stuck in the groove 21.When opening groove 21, protrude 31 outlets that can open groove 21, stationary axle extending end 41 just can break away from groove 21, and upper and lower hinge 1,2 is broken away from.On stationary axle 4, be with spring 25.

One end of spring 25 is stuck in the upper hinge 1, and the other end is stuck in down in the hinge 2.Because spring 25 plays the effect of buffering, make the utility model can be used for the situation of needs support than heavy parts.

Screens lid 3 is " ∪ " shape, the both sides inwall of the opening end of screens lid 3 is provided with fulcrum 5, be provided with the hole clipping 6 that can snap in fulcrum 5 on hinge 2 opposite positions down, the fulcrum 5 of screens lid 3 be may be stuck in down in the hole clipping 6 of hinge 2, the opening end of screens lid 3 is connected with following hinge, and screens lid 3 can be center of circle rotation along fulcrum 5 and hole clipping 6.

Upper hinge 1 comprises decorative sheet 11 and mounting plate 12, and same, following hinge 2 comprises decorative sheet 21 and mounting plate 22, is provided with several fixed holes 13,23 on mounting plate 12 and mounting plate 22.The object that can utilize fixed hole 13,23 and need hinge is installed is connected to a fixed.Installation steps of the present utility model are as follows: will go up earlier, following hinge is installed in respectively to be needed to install on two parts of hinge, and the fulcrum 5 of screens lid 3 is stuck in down in the hole clipping 6 of hinge 2, screens lid 3 is pushed the position of opening, simultaneously the stationary axle extending end 41 of stationary axle 4 on the upper hinge 1 is inserted into down on the hinge 2 in the corresponding grooves 21, again screens lid 3 is pushed closed position, this moment, hinge can normally use; In the time will dismantling two parts, earlier screens lid 3 is pushed the position of opening, the stationary axle extending end 41 of upper hinge 1 is taken out from the groove 21 of hinge 2 down get final product.

This kind hinge can be used on the parts that profile is two needs rotations of sphere, works to connect two parts.Also can be used on the parts that two needs of other profiles rotate.As shown in Figure 9, on, following hinge 1,2 is respectively by fixed hole 13,23, is screwed at needs in relative rotation on two parts, to make two parts can realize relatively rotating; 3 on screens lid can keep two rotatable parts can not break away from mutually in rotation process, plays the effect of safety protection.Only need when needing again in addition to dismantle two parts screens lid 3 opened and get final product, and do not need to dismantle other fastening piece, thereby make dismantlement work become very convenient.
