[0004] The utility model discloses a door frame free excavation three -dimensional adjustable hidden hydraulic hinge, which adopts the right hinge of convex shape and the right hinge arm of Z shape, and the sliding sleeve slides in the inclined sliding groove of the right hinge, so that the hinge folding is more smooth, and the wear is smaller

[0005] The right hinge front and rear end screw hole section of the utility model is provided with cover end, and the left hinge top is provided with the recess that is matched with the overall shape of the right hinge, and the right hinge can be embedded into the recess of the left hinge top when the left hinge and the right hinge are folded.

[0006] The utility model discloses a door frame free excavation three -dimensional adjustable hidden hydraulic hinge, which adopts the right hinge of convex shape and the right hinge arm of Z shape, and the sliding sleeve slides in the inclined sliding groove of the right hinge, so that the hinge folding is more smooth, and the wear is smaller

[0007] The utility model discloses the advantages are simple structure, stable work, folding smooth, low noise, hide effect is better after installation, is not easy to damage, and maintenance is convenient. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is the whole structure schematic diagram of the utility model;

[0009] Figure 2 It is the exploded view schematic diagram of the utility model. CONCRETE IMPLEMENTING METHOD

[0010] According to Figure 1 、 Figure 2 It is shown in the embodiment described in the front, back, left, right and so on direction with Figure 1 For reference, the utility model is based on left hinge 1, right hinge 2, buffer 3, left page arm 4, right page arm 5, and the characteristics are that there is sliding sleeve 6, the page plate of right hinge 2 is convex from back to front long axis cross section, the recess is set up in the middle top of right hinge 2, and the sliding groove is set up in the front and rear two sides in the recess;Right page arm 5 is Z-shaped bending, and the pivot 5.1 is set up in the middle turning point of right page arm 5 from back to front direction, right page arm 5 is hinged with the middle place of left page arm 4 through pivot 5.1, and the sliding shaft 5.2 is set up in the right end of right page arm 5, and the sliding sleeve 6 is respectively set up in the two ends sliding shaft, and two sliding sleeves are respectively inserted into the two sliding grooves of right hinge 5, and can slide along the sliding groove. The cover end 2.1 of right hinge 2 front and rear two end screw hole section can cover the screw hole of right hinge two ends, the recess that is matched with the overall shape of right hinge 2 is set up in the top of left hinge 1, and right hinge 2 can be embedded into the recess in the top of left hinge 1 when left hinge 1 and right hinge 2 are folded.
