[0042] 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.

[0043] First embodiment:

[0044] like Figure 2 As shown, a hinge structure for doors and windows provided by the first embodiment of the utility model 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 part 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 part 5 is installed on a specific area of ​​the window sash fixing plate 2 (described in detail below) and is connected to the window sash, so as to resist wind pressure.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] like Figure 2 As shown, in the above embodiment, the wind pressure resistant member 5 is installed on the window sash fixing plate 2 and is located between the first connecting hole 21 and the proximal end 22 of the window sash fixing plate 2 (i.e., the above-mentioned specific area), and the wind pressure resistant member 5 is connected to the window sash to resist wind pressure. Specifically, the wind pressure resistant member 5 is a self-tapping screw, which passes through the connecting rod assembly 3 and the window sash fixing plate 2 and self-taps into the window sash. It should be noted that the automatic screw 5 needs to pass through the connecting rod assembly 3 and the window sash fixing plate 2 from the above-mentioned specific area and self-tapping into the window sash. It can be understood that the use of self-tapping screws as the wind pressure resistant member 5 has a simple structure, is easy to install, and has a lower overall cost. In addition, there is no need to drill holes in the window sash fixing plate 2 in advance, and the installation position can be freely adjusted within a specific area, which is more optimal for construction.

[0049] In the above embodiment, preferably, Figure 3As shown, the limiting member 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 limiting member 6 to the window sash fixing plate 2. In addition, a limiting portion 312 is provided at a position corresponding to the thick-necked 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-necked section 61 abuts against the limiting portion 312 to limit the rotation of the window sash fixing plate 2. Therefore, by utilizing the limiting member 6 in conjunction with the limiting portion 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.

[0050] 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.

[0051] In addition, if Figure 2 As 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 .

[0052] Second embodiment:

[0053] like Figure 4 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 employed, thereby omitting the connecting shaft 4.

[0054] Specifically, in this embodiment, screws are directly used as wind pressure-resistant members 5, and the screws are connected to the window sash by sequentially passing through the first connecting rod 31 and the window sash fixing plate 2. It can be understood that the use of screws as wind pressure-resistant members 5 can not only serve as a connection, but also, because the location of the wind pressure-resistant members 5 is still within the above-mentioned specific area, the connection member itself also serves as a reinforcement point, thereby effectively resisting wind pressure.

[0055] In addition to the above-mentioned structure, the structures of the window frame fixing plate 1, the window sash fixing plate 2, the connecting rod assembly 3 and the limiting member 6 of this embodiment are the same as those of the first embodiment and are not described again here.

[0056] Third embodiment:

[0057] like Figure 5 FIG. 3 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.

[0058] Specifically, in this embodiment, the first end of the first connecting rod 31 is rotatably connected to the window sash fixing plate 2 via the connecting shaft 4, and the connecting member 5 passes through the connecting shaft 4 and is connected to the window sash. It is understandable that, compared with the first embodiment, since the connecting member 5 is directly inserted into the connecting shaft 4, and the connecting shaft 4 is pre-formed with a center hole 41, the convenience of installing the connecting member 5 is improved, and self-insertion into the window sash from other positions is avoided. Compared with the second embodiment, in this embodiment, the first connecting rod 31 can be rotatably connected to the window sash fixing plate 2 via the connecting shaft 4, so that the rotation is not transmitted to the wind pressure resistant member 5, thereby avoiding the situation where the wind pressure resistant member 5 becomes loose due to rotation, thereby improving the overall stability.

[0059] Except for the above differences, the rest of the structure of this embodiment is the same as that of the first embodiment and will not be described again here.

[0060] Fourth embodiment:

[0061] like Figure 6 As shown, the fourth embodiment of the present invention provides another hinge structure for doors and windows, including a window frame fixing plate 1, a window sash fixing plate 2, a connecting rod assembly 3, a connecting shaft 4, a wind pressure resistant member 5, and a stopper 6. Compared with the first embodiment, this embodiment differs in that the wind pressure resistant member 5 has a different structural form.

[0062] Specifically, such as Figure 5 As shown, a limit member 6 is provided between the connection point of the first end of the first connecting rod 31 and the proximal end of the window sash fixing plate 2 (i.e., the aforementioned specific area). When the window sash fixing plate 2 rotates a preset angle relative to the window frame fixing plate 1, the limit member 6 abuts against the limit portion 312 of the first connecting rod 31 to limit the opening angle of the window sash. In addition, the wind pressure-resistant member 5 is a connecting member that passes through the limit member 6 and is connected to the window sash, thereby forming a reinforcement point on the window sash fixing plate 2 near the window frame side. When the window sash is subjected to wind pressure, misalignment and shearing are less likely to occur between the window sash fixing plate 2 and the window sash, thereby effectively resisting the wind pressure.

[0063] Except for the above differences, the rest of the structure of this embodiment is the same as that of the first embodiment and will not be described again here.

[0064] Fifth embodiment:

[0065] like Figure 7As shown, the fifth embodiment of the present invention provides another hinge structure for doors and windows, including a window frame fixing plate 1, a window sash fixing plate 2, a connecting rod assembly 3, a connecting shaft 4, a wind pressure resistant member 5, and a stopper 6. Compared with the first embodiment, this embodiment differs in that the wind pressure resistant member 5 has a different structural form.

[0066] Specifically, in this 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 the top of the connecting column 5 extends toward the window sash. Figure 8 As shown, a strip groove 201 is provided at a position on the window sash 20 corresponding to the top of the connecting column 5 , and the strip groove 201 cooperates with the top of the connecting column 5 to resist wind pressure.

[0067] In addition, if Figure 9 As shown, in the above embodiment, preferably, a threaded hole 63 is formed in the center of the stopper 6, and the bottom of the connecting column 5 has a threaded section 51, which is threadedly connected to the threaded hole 63 to movably connect the stopper 6 to the bottom of the connecting column 5. Therefore, different sizes of stoppers 6 can be selected as needed to achieve different limiting effects on the window sash fixing plate 2.

[0068] 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.

[0069] Sixth embodiment:

[0070] like Figure 10 As shown, the sixth embodiment of the present invention further provides a door and window 100, comprising a window frame 10, a window sash 20 and the hinge structure 30 described in any one of the second to fifth embodiments.

[0071] In the description of this specification, reference to the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

In addition, those skilled in the art may combine and integrate different embodiments or examples described in this specification, as well as features of different embodiments or examples, unless they are mutually inconsistent.

[0072] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature.
