The first adjustment structure 31 includes a first transverse bar tooth 311 and a first longitudinal bar tooth 312. The second adjustment structure 41 includes a second transverse bar tooth 411 and a second longitudinal bar tooth 412.

[0080] When the hinge assembly 3 needs to be adjusted in position after being installed on the profile 1, the user only needs to loosen the connecting piece 5, then adjust the hinge assembly 3 to a suitable position, and then tighten the connecting piece 5 to adjust the position of the hinge assembly 3. At this time, the first transverse bar tooth 311 is engaged with the second transverse bar tooth 411, and the first longitudinal bar tooth 312 is engaged with the second longitudinal bar tooth 412, thereby limiting the hinge assembly 3 in both the transverse and longitudinal directions, effectively ensuring that the adjustment block 4 and the hinge assembly 3 will not be displaced in the transverse and longitudinal directions by themselves due to the gravity of the doors and windows or other forces, and the structure is stable and reliable.

[0081] In this embodiment, please refer to Figure 2 The hinge assembly 3 includes: a frame member 32, a fan member 33 and a plurality of hinge members 34.

[0084] In this embodiment, the frame member 32 is provided with a through hole 321 (such as Figure 3 As shown), the size of the through hole 321 is larger than that of the connecting member 5, so that the frame member 32 can be displaced unidirectionally or multi-directionally relative to the profile 1 when the connecting member 5 is loosened.

[0085] The setting of the through hole 321 is mainly used to limit the movement range of the frame member 32, to prevent the frame member 32 from moving out of the meshing range of the first transverse bar tooth 311 and the second transverse bar tooth 411, and / or to prevent the frame member 32 from moving out of the meshing range of the first longitudinal bar tooth 312 and the second longitudinal bar tooth 412, thereby preventing the adjustment block 4 from being unable to limit the hinge assembly 3 in the longitudinal and / or transverse directions.

[0086] Furthermore, the frame member 32 of this embodiment is provided with a step groove 322 (such as Figure 3 and Figure 4 As shown in the figure, the through hole 321 is arranged in the step groove 322, and the second adjustment structure 41 is arranged around the through hole 321 in the step groove 322. The longitudinal length of the step groove 322 is greater than the longitudinal length of the adjustment block 4, and the transverse length of the step groove 322 is greater than the transverse length of the adjustment block 4, so that the adjustment block 4 can move in the step groove 322 when the connecting member 5 is loosened.

On the other hand, it can increase the stability of the adjustment block 4 and prevent the adjustment block 4 from shaking or falling off during the movement. In addition, the design of the step groove 322 also makes the connection between the frame 32 and the adjustment block 4 more firm, thereby improving the service life and reliability of the entire device.

[0087] In this embodiment, please refer to Figure 2One end of the hinge member 34 is rotatably connected to the frame member 32 via a first rotating shaft 6, and the other end is rotatably connected to the fan member 33 via a second rotating shaft 7;

[0088] The size of the first rotating shaft 6 is the same as that of the second rotating shaft 7 .

[0089] The size of the first rotating shaft 6 is the same as that of the second rotating shaft 7, so that the rotating shafts of this embodiment can adopt the same universal design of accessories, making storage and management more convenient and effectively reducing the difficulty and cost of storage.

[0090] For details, please refer to Figure 8-10 , connecting holes 341 for passing the first rotating shaft 6 and the second rotating shaft 7 are provided on both sides of the hinge member 34, and a connecting cavity 323 for installing one side of the hinge member 34 is provided on the frame member 32; the end surface of the frame member 32 is provided with two first mounting holes 324 passing through the connecting cavity 323, and the first mounting hole 324 is used to pass the first rotating shaft 6; the first rotating shaft 6 passes through the first mounting hole 324 at one end of the frame member 32, the connecting hole 341, and the first mounting hole 324 at the other end of the frame member 32 in sequence; a connecting portion 331 for installing one end of the hinge member 34 is provided on the fan member 33; two second mounting holes 332 passing through the connecting portion 331 are provided on the end surface of the fan member 33; the second rotating shaft 7 passes through the second mounting hole 332 at one end of the fan member 33, the connecting hole 341, and the second mounting hole 332 at the other end of the fan member 33 in sequence.

[0091] In this embodiment, the two end faces of the hinge member 34 are arranged flush, and the material of the hinge member 34 is an extruded aluminum profile. Therefore, the hinge member 34 only needs to be cut according to the required length during the processing, and no additional processing steps are required. This processing method is simple and efficient.

[0092] In this embodiment, two adjusting blocks 4 and two connecting members 5 are provided, and the first adjusting structures 31 are provided at both ends of the frame member 32;
