[0045] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] First embodiment:

[0047] like Figure 2 As shown, a hinge structure for doors and windows provided by the first embodiment of the present invention includes a window frame fixing plate 1, a window sash fixing plate 2, a connecting rod assembly 3, a connecting shaft 4 and a wind pressure resistant component 5. The window frame fixing plate 1 and the window sash fixing plate 2 are respectively installed on the window frame and the window sash, and the connecting rod assembly 3 is connected between the window frame fixing plate 1 and the window sash fixing plate 2 so that the window sash fixing plate 2 can rotate relative to the window frame fixing plate 1. The connecting shaft 4 is connected between the window sash fixing plate 2 and the connecting rod assembly 3 to realize the mutual hinge connection between the window sash fixing plate 2 and the connecting rod assembly 3 to form a stable hinge structure. The wind pressure resistant component 5 is installed on the window sash fixing plate 2 and connected to the window sash, so as to resist wind pressure.

[0048] like Figure 2 As shown in the above embodiment, the window frame fixing plate 1 is mounted on the window frame and has a generally rectangular plate-like structure. The window frame fixing plate 1 is slidably engaged with a slider 11 and further provided with a fixing block 12. The fixing block 12 and the slider 11 are spaced apart along the length of the window frame fixing plate 1.

[0049] like Figure 2As shown, in the above embodiment, the window sash fixing plate 2 is fixed to the window sash and is located on one side of the window frame fixing plate 1. The window sash fixing plate 2 is a generally rectangular plate-shaped structure, and a first connecting hole 21 is formed in the area near the proximal end of the window sash fixing plate 2 (i.e., the end closest to the window frame fixing plate) for hinged connection with the connecting rod assembly 3.

[0050] like Figure 2 As shown, in the above embodiment, the connecting rod assembly 3 is connected between the window frame fixing plate 1 and the window sash fixing plate 2, so that the window sash fixing plate 2 can rotate around the window frame fixing plate 1. Specifically, in this embodiment, the connecting rod assembly 3 includes a first connecting rod 31, a second connecting rod 32 and a third connecting rod 33. Among them, the first end of the first connecting rod 31 (i.e. Figure 2 The left end of the middle part) is hinged to the fixed block 12, and the other end (i.e. Figure 2 A second connecting hole 311 is provided on the right end of the first connecting rod 31, and the second connecting hole 311 corresponds to the first connecting hole 21, so that the connecting shaft 4 can pass through the first connecting hole 21 and the second connecting hole 311, thereby hingedly connecting the window sash fixing plate 2 to the right end of the first connecting rod 31. One end of the second connecting rod 32 (i.e. Figure 2 The left end of the slider 11 is hinged to the other end (i.e. Figure 2 The right end of the third connecting rod 33 is hinged to the middle of the window sash fixing plate 2. Figure 2 The left end of the middle part) is hinged to the fixed block 12, and the other end (i.e. Figure 2 The right end in FIG) is hinged to the middle part of the second connecting rod 32. Thus, the connecting rod assembly 3 composed of the three-link structure is used to realize the transmission connection between the window frame fixing plate 1 and the window sash fixing plate 2.

[0051] In another embodiment, the connecting rod assembly 3 includes a first connecting rod, a second connecting rod and a third connecting rod. The first end of the first connecting rod is rotatably connected to the window sash fixing plate, and the second end of the first connecting rod is rotatably connected to the window frame fixing plate. One end of the second connecting rod is slidably connected to the window frame fixing plate, and the other end is hinged to the window sash fixing plate. One end of the third connecting rod is slidably connected to the window frame fixing plate, and the other end is hinged to the middle part of the first connecting rod. In yet another embodiment, the connecting rod assembly 3 includes a first connecting rod, a second connecting rod and a third connecting rod. The first end of the first connecting rod is rotatably connected to the window sash fixing plate, and the second end of the first connecting rod is rotatably connected to the window frame fixing plate. One end of the second connecting rod is hinged to the window frame fixing plate, and the other end is hinged to the window sash fixing plate. One end of the third connecting rod is slidably connected to the window frame fixing plate, and the other end is hinged to the middle part of the first connecting rod.

[0052] like Figure 2As shown, in the above embodiment, the wind pressure resistant member 5 is a connecting column. The bottom of the connecting column 5 is connected to the window sash fixing plate 2 and is located between the first connecting hole 21 and the distal end 22 of the window sash fixing plate 2 and close to the first connecting hole 21. In addition, the top of the connecting column 5 extends toward the window sash, as shown in FIG. Figure 3 As shown, a strip groove 201 is formed on the window sash 20 at a position corresponding to the top of the connecting post 5. The strip groove 201 cooperates with the top of the connecting post 5. It can be understood that the strip groove 201 cooperates with the top of the connecting post 5 to form a reinforcement point in the area where the two contact. When the window sash is subjected to wind pressure, the window sash fixing plate 2 and the window sash are less likely to be misaligned and sheared, thereby effectively resisting the wind pressure.

[0053] In the above embodiment, preferably, Figure 2A As shown, the connecting shaft 4 has a central hole 41 at its center, through which a connecting member 7 is inserted for connecting the sash fixing plate 2 to the window sash. Thus, on the one hand, the connecting shaft 4 itself achieves the mutual hinge connection between the sash fixing plate 2 and the connecting rod assembly 3, forming a stable hinge structure; on the other hand, the interaction between the connecting shaft 4 and the connecting member 7 achieves a fixed connection between the sash fixing plate 2 and the window sash, eliminating the need for additional screw holes in the sash fixing plate and avoiding the reduction in strength caused by material reduction.

[0054] In the above embodiment, preferably, Figure 2 and Figure 4 As shown, the hinge structure also includes a limiter 6. The limiter 6 includes a thick diameter section 61 and a thin diameter section 62. The thin diameter section 62 is inserted into the pressure-resistant hole 23 of the window sash fixing plate 2, thereby connecting the limiter 6 to the window sash fixing plate 2. In addition, a limiter 312 is provided at a position corresponding to the thick neck section 61 on the first connecting rod 31 of the connecting rod assembly 3. When the window sash fixing plate 2 rotates by a preset angle relative to the window frame fixing plate 1, the thick neck section 61 abuts against the limiter 312 to limit the rotation of the window sash fixing plate 2. Therefore, by utilizing the limiter 6 in conjunction with the limiter 312, while resisting wind pressure, the rotation of the window sash fixing plate 2 can also be limited, thereby further ensuring the safety of the window sash opening.

[0055] In the above embodiment, the connecting rod assembly 3 preferably further includes a seal 34. This seal 34 is disposed between the first connecting rod 31 and the window sash fixing plate 2 and connected to the window sash fixing plate 2 via the thin-diameter section 62 of the stopper 6. The end of the seal 34, distal from the connecting shaft 4, is formed with a pre-set abutment tip 341. This abutment tip 341 is configured to engage with the end corner 13 of the window frame fixing plate 1, thereby guiding and sealing the window sash during closing, thereby improving the window sash's sealing effect.

[0056] In addition, if Figure 2As shown, in the above embodiment, preferably, the window sash fixing plate 2 is provided with a fixing hole 24 , and the fixing hole 24 is fixedly connected to the window sash through a fixing member 25 , thereby improving the installation stability of the window sash fixing plate 2 .

[0057] Second embodiment:

[0058] like Figure 5 FIG. 1 shows another hinge structure for doors and windows provided in a second embodiment of the present invention, comprising a window frame fixing plate 1, a window sash fixing plate 2, a connecting rod assembly 3, a wind-resistant member 5, and a stopper 6. Compared to the first embodiment, this embodiment differs in that the wind-resistant member 5 is connected at a different location.

[0059] Specifically, in this embodiment, the wind pressure resistant member 5 is disposed in a specific area of ​​the window sash fixing plate 2, which is between the first connecting hole 21 and the proximal end 26 of the window sash fixing plate 2. It is understood that because this specific area is closer to the window frame, the reinforcement point formed by the strip groove 201 and the connecting column 5 is closer to the window frame, thereby being able to more effectively resist wind pressure.

[0060] Except for the above structure, the rest of the structure of this embodiment is the same as that of the first embodiment and will not be described again here.

[0061] Third embodiment:

[0062] like Figure 6 FIG. 1 shows another hinge structure for doors and windows provided by the third embodiment of the present invention, comprising a window frame fixing plate 1, a window sash fixing plate 2, a connecting rod assembly 3, a connecting shaft 4, a wind-resistant member 5, and a stopper 6. Compared to the first embodiment, this embodiment differs in that the wind-resistant member 5 is connected at a different location, and the stopper 6 is detachably connected to the wind-resistant member.

[0063] Specifically, in this embodiment, the wind pressure-resistant member 5 is a connecting column disposed in a specific region of the window sash fixing plate 2, that is, between the first connecting hole 21 and the proximal end 26 of the window sash fixing plate 2. It is understood that because this specific region is closer to the window frame, the reinforcement point formed by the strip groove 201 and the connecting column 5 is closer to the window frame, thereby being able to more effectively resist wind pressure.

[0064] Furthermore, a threaded hole 63 is formed in the center of the stopper 6, and a threaded section 51 is formed at the bottom of the connecting post 5. The threaded section 51 is threadedly connected to the threaded hole 63 to movably connect the stopper 6 to the bottom of the connecting post 5. Thus, stoppers 6 of different sizes can be selected as needed to achieve different limiting effects on the sash fixing plate 2.

[0065] Except for the above-mentioned different structures, the rest of the structures are the same as those of the first embodiment and will not be described again.

[0066] Fourth embodiment:
