The upper end of connecting axle 240 stretches into first rotation hole 130, because fan part 100 is connected in the fan section bar, then because the gravity of fan section bar self, the lower extreme that makes first regulating part 150 supports in first regulating part 150 all the time in the tip that connecting axle 240 stretches into first rotation hole 130, the upper end of connecting axle 240 promptly all the time to make the fan section bar can be suspended in the air, be convenient for the fan section bar to rotate relative frame section bar, so that door and window is closed and open. Wherein the first adjustment member 150 is a screw.

Further, when the first adjusting member 150 is rotated, the first adjusting member 150 moves downward relative to the hole wall of the first rotating hole 130, and since the lower end of the first adjusting member 150 is always abutted to the end of the connecting shaft 240 extending into the first rotating hole 130 and the frame profile is fixed, the connecting shaft 240 is limited above the bottom wall of the blind hole, so that the position of the first adjusting member 150 in the vertical direction is not changed. Since the position of the first adjusting member 150 in the vertical direction is not changed, the first connecting member 120 drives the fan-shaped section to move upward through the screw transmission, so that the depth of the connecting shaft 240 extending into the first rotating hole 130 is reduced, and the installation height of the fan-shaped section is increased.

The upper end of the connecting shaft 240 extends into the blind hole, and since the sash member 100 is connected to the sash profile, the bottom wall of the blind hole is always abutted to the upper end of the connecting shaft 240 due to the gravity of the sash profile, that is, the upper end of the connecting shaft 240 is always supported by the first connecting member 120, so that the sash profile can be suspended in the air, and the sash profile can rotate relative to the frame profile to close and open the door and window. Wherein the second adjustment member 250 is a screw.

Further, when the second adjusting member 250 is rotated such that the second adjusting member 250 moves up or down with respect to the hole wall of the second rotating hole 230, since the second adjusting member 250 is used to support the connecting shaft 240, the connecting shaft 240 moves up or down in synchronization with the second adjusting member 250. Because the bottom wall of the blind hole is always abutted to the end of the connecting shaft 240 extending into the first rotating hole 130, the first connecting piece 120 also moves up or down synchronously, thereby changing the depth of the connecting shaft 240 extending into the second rotating hole 230 and adjusting the installation height of the fan-shaped material.

Referring also to fig. 1, 2 and 3, in one embodiment, the hinge structure includes: a first adjustment member 150 and a second adjustment member 250; the first adjusting member 150 is in threaded connection with the hole wall of the first rotating hole 130, one end of the connecting shaft 240 extending into the first rotating hole 130 is supported on the first adjusting member 150, and the first adjusting member 150 can rotate to adjust the depth of the connecting shaft 240 extending into the first rotating hole 130; the second adjusting member 250 is threadedly coupled to the hole wall of the second rotating hole 230, the second adjusting member 250 is supported by the connecting shaft 240, and the second adjusting member 250 can rotate to adjust the depth of the connecting shaft 240 extending into the second rotating hole 230.

The upper end of the connecting shaft 240 extends into the first rotating hole 130, and the sash member 100 is connected to the sash profile, so that the lower end of the first adjusting member 150 is always abutted to the end of the connecting shaft 240 extending into the first rotating hole 130 due to the gravity of the sash profile, that is, the upper end of the connecting shaft 240 is always supported on the first adjusting member 150, so that the sash profile can be suspended in the air, and the sash profile can rotate relative to the frame profile to close and open the door and window.

Furthermore, when the first adjusting member 150 is rotated, the first adjusting member 150 moves downward relative to the hole wall of the first rotating hole 130, and since the lower end of the first adjusting member 150 is always abutted to the end of the connecting shaft 240 extending into the first rotating hole 130 and the frame profile is fixed, the connecting shaft 240 is limited above the bottom wall of the blind hole, so that the position of the first adjusting member 150 in the vertical direction is not changed. Since the position of the first adjusting member 150 in the vertical direction is not changed, the first connecting member 120 drives the fan-shaped section to move upward through the screw transmission, so that the depth of the connecting shaft 240 extending into the first rotating hole 130 is reduced, and the installation height of the fan-shaped section is increased.

In the application, the installation height of the fan-shaped section is adjusted through the first adjusting piece 150 and/or the second adjusting piece 250, so that the lock cylinder on the fan-shaped section can be accurately aligned to the lock cap on the frame section, and the assembly error of the fan-shaped section is reduced.
