[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc. indicating orientation or positional relationships are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0022] The accompanying drawings are specific embodiments of the present utility model. As Figures 1 - 5 shown, the present utility model is a three-dimensionally adjustable concealed casement hinge, which successively includes an L-shaped frame fixing member 7, a sliding member 2, a rotating member 4, and an L-shaped sash fixing member 1 from bottom to top. The sliding member 2 and the rotating member 4 are sheet metal special-shaped parts as Figure 3 , Figure 5 shown. A second chute 703 is horizontally opened at one end of the L-shaped frame fixing member 7. A slider 10 is slidably connected in the second chute 703. The cross-section of the slider 10 is in an inverted T shape. One end of the slider 10 is hinged to one end of the sliding member 2 through a first rotating connecting member 13. The other end of the sliding member 2 is fixed with a sliding nail 12, and the sliding nail 12 is slidably connected with a first chute 102. A first chute 102 is horizontally opened on the L-shaped sash fixing member 1. One end of the L-shaped sash fixing member 1 is hinged to the rotating member 4, and the other end of the rotating member 4 is hinged to the L-shaped frame fixing member 7. A waist-shaped hole 15 and a third through hole 702 are opened on the L-shaped frame fixing member 7. The waist-shaped hole 15 and the third through hole 702 are respectively installed with a connecting piece 9 through a second rotating connecting member 14 and a second eccentric member 5. The intersection point of the sliding member 2 and the rotating member 4 is hinged through a first eccentric member 3. The rotational torque of the first eccentric member 3 is 2-6 N*M. A first through hole 401 is opened on the rotating member 4, and a second through hole 201 is opened on the sliding member 2. The first eccentric member 3 is riveted to the rotating member 4 and the sliding member 2. An articulated hole 101 is vertically opened at the end of the L-shaped sash fixing member 1. One end of the rotating member 4 is vertically provided with a hinge shaft 11 that matches the rotating member 4. The second chute 703, the hinge shaft 11, and the articulated hole 101 are located on the same side. A tightening through hole 701 is opened on the L-shaped frame fixing member 7. There are at least two tightening through holes 701. A fixing piece 8 and a tightening member 6 are installed on the tightening through hole 701. Rotating the tightening member 6 to make the fixing piece 8 screw into the profile groove can complete the installation. A hexagonal through hole 601 is opened on the tightening member, and a screw can also be installed on the hexagonal through hole 601 to further improve the firmness of the hinge installed on the window sash.

[0023] During use, the L-shaped sash fixing member 1 can rotate around the hinge shaft 11, and the rotating member 4 can rotate around the second rotating connector 14; the two ends of the sliding member 2 can rotate and slide in the first slide groove 102 and the second slide groove 703 respectively; at the same time, the rotating member 4 and the sliding member 2 are hinged to each other with the first eccentric member 3 as the axis. Therefore, after the device is installed, pushing the window will drive the L-shaped sash fixing member 1 to extend, causing the hinge assembly of the utility model to extend, so that the window can be opened horizontally. At the same time, since the eccentric position of the first eccentric member 3 can be adjusted using a hexagonal wrench 16, the position of the hinge point where the rotating member and the sliding member 2 intersect can be changed, thereby adjusting the indoor and outdoor directions of the hinge; since the eccentric position of the second eccentric member 5 can be adjusted using a hexagonal wrench 16, the connecting piece 9 can be adjusted in the left and right directions, thereby driving the second rotating connector 14 to adjust left and right in the waist hole 15, thereby driving the L-shaped sash fixing member 1 to move left and right, thereby adjusting the left and right directions of the hinge. The utility model has a simple structure, can realize the adjustment of the hinge in three-dimensional directions, reduces the loss caused by the processing error of the profile, is easy to install, has strong practicality, good structural strength, and is widely applicable.
