[0008] Furthermore, positioning ribs are installed on the outer side of the sliding sleeve, and a plurality of slots are provided on the inner wall of the fan hinge, and the positioning ribs are plugged into the slots.

[0009] The beneficial effect of adopting the above further solution is that by installing positioning ribs on the outside of the sliding sleeve, the positioning ribs are plugged into the slots. When the user plugs the positioning ribs into slots at different positions, the overlap amount of the frame hinge and the leaf hinge can be adjusted.

[0010] Further, a positioning hole is provided on the bottom side of the frame hinge, and the inner thread of the positioning hole is connected with a first screw, and one end of the first screw is abutted with the positioning groove.

[0011] The beneficial effect of adopting the above further solution is that the screw rod can be fixed by connecting the first screw with the inner thread of the positioning hole and making one end of the first screw abut against the positioning groove formed on the bottom side of the screw rod.

[0012] Furthermore, a pair of first mounting holes is opened on one side of the frame hinge, a second mounting hole is opened on one side of the frame hinge between the pair of first mounting holes, and a second screw is arranged inside the second mounting hole.

[0013] The beneficial effect of adopting the above further solution is that by providing the first mounting hole, it is convenient for the user to pre-fix the frame hinge with the first locking block, and by providing the second mounting hole, it is convenient for the user to fix the frame hinge with the second screw.

[0014] Furthermore, a third screw is movably inserted into the interior of each of the first mounting holes, and one end of each of the third screws is threadedly connected to a first locking block.

[0015] The beneficial effect of adopting the above further scheme is that by threading the first locking block at one end of the third screw, the user can insert the first locking block into the groove of the profile, and cooperate with the rotation of the third screw to conveniently fix the frame hinge on the groove of the profile.

[0016] Furthermore, a pair of third mounting holes is provided on one side of the fan hinge, a fourth mounting hole is provided on one side of the fan hinge between the pair of third mounting holes, and a fourth screw is provided inside the fourth mounting hole.

[0017] The beneficial effect of adopting the above further scheme is that by opening a third mounting hole, the user can use the fifth screw in conjunction with the second locking block to pre-fix the door hinge on the profile groove, and by opening a fourth mounting hole and arranging a fourth screw inside the hole, the door hinge can be installed using the fourth screw.

[0018] Furthermore, a fifth screw is movably inserted into the interior of each of the third mounting holes, and one end of the fifth screw is threadedly connected to a second locking block.

The liftable hinge is threadedly connected to a threaded groove set at an eccentric position inside the sliding sleeve by connecting a screw rod through the internal thread of the frame hinge. When the sliding sleeve rotates, the sliding sleeve can move up and down. By slidingly connecting the fan hinge and the sliding sleeve, when the fan hinge rotates, the fan hinge can be driven to move up and down under the action of the sliding sleeve. By arranging a washer on the screw rod, the upper and lower ends of the washer respectively abut against the bottom end of the fan hinge and the top end of the frame hinge, the wear between the fan hinge and the frame hinge can be reduced. By snapping on the dust cover, the upper end of the fan hinge can be closed to prevent dust from entering. By installing a positioning rib on the outer side of the sliding sleeve, the positioning rib is plugged into the slot. When the user plugs the positioning rib into the slots at different positions, the overlap amount of the frame hinge and the fan hinge can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
