[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 described embodiments 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 creative work are 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 in 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 an anti-wind pressure member 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 anti-wind pressure member 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 installed on the window frame and is roughly in a rectangular plate structure. The window frame fixing plate 1 is slidably matched with a slider 11, and the window frame fixing plate 1 is also provided with a fixing block 12; the fixing block 12 and the slider 11 are spaced apart in the length direction of the window frame fixing plate 1.

[0046] Figure 2As shown, in the above embodiment, the window sash fixing plate 2 is fixed on the window sash and is located on one side of the window frame fixing plate 1. The window sash fixing plate 2 is generally a rectangular plate structure, and a first connecting hole 21 is provided in the area where the proximal end of the window sash fixing plate 2 (i.e., the end close to the window frame fixing plate) is located, for being hinged 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 slider 11, and 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 the middle of the second connecting rod 32 is hinged. Thus, the connecting rod assembly 3 formed by 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, and the self-tapping screw 5 passes through the connecting rod assembly 3 and the window sash fixing plate 2, and self-taps into the window sash. Among them, 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 pre-drill holes in the window sash fixing plate 2, 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 relative to the window frame fixing plate 1 by a preset angle, the thick-necked section 61 abuts against the limiting portion 312 to limit the rotation of the window sash fixing plate 2. Therefore, by using the limiting member 6 in conjunction with the limiting portion 312, the window sash fixing plate 2 can be limited in rotation while resisting wind pressure, thereby further ensuring the safety of the window sash opening.

[0050] In the above embodiment, preferably, the connecting rod assembly 3 further includes a sealing member 34. The sealing member 34 is disposed between the first connecting rod 31 and the window sash fixing plate 2, and is connected to the window sash fixing plate 2 through the thin-diameter section 62 of the stopper 6. An abutting tip 341 of a preset shape is formed at one end of the sealing member 34 away from the connecting shaft 4, and the abutting tip 341 is used to cooperate with the end wrap angle 13 of the window frame fixing plate 1, thereby playing a guiding and sealing role in closing the window sash, and improving the closing effect of the window sash.

[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, so as to improve the installation stability of the window sash fixing plate 2.

[0052] Second embodiment:

[0053] like Figure 4 As shown, another hinge structure for doors and windows provided in the second embodiment of the present invention comprises a window frame fixing plate 1, a window sash fixing plate 2, a connecting rod assembly 3, a wind pressure resistant member 5 and a stopper 6. Compared with the first embodiment, the difference of this embodiment is that the wind pressure resistant member 5 is adopted, thereby omitting the connecting shaft 4.

[0054] Specifically, in this embodiment, screws are directly used as the wind pressure resistant member 5, so that the screws are connected to the window sash after passing through the first connecting rod 31 and the window sash fixing plate 2 in sequence. It can be understood that the use of screws as the wind pressure resistant member 5 can play a connecting role on the one hand, and on the other hand, since the position of the wind pressure resistant member 5 is still located in the above-mentioned specific area, it is equivalent to that the connecting member itself also plays a role of a reinforcement point, so that it can effectively resist 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 in detail here.

[0056] Third embodiment:

[0057] like Figure 5 As shown, another hinge structure for doors and windows provided in the third embodiment of the present invention comprises 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 limiting member 6. Compared with the first embodiment, the difference of this embodiment is that the connection position of the wind pressure resistant member 5 is different.

[0058] Specifically, in this embodiment, the first end of the first connecting rod 31 is rotatably connected to the window sash fixing plate 2 through the connecting shaft 4, and the connecting member 5 passes through the connecting shaft 4 and is connected to the window sash. It can be understood 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 can be improved, and it is avoided that the connecting member 5 is self-drilled into the window sash from other positions. Compared with the second embodiment, in this embodiment, the first connecting rod 31 can be rotatably connected to the window sash fixing plate 2 through the connecting shaft 4, so that the rotation will not be transmitted to the wind pressure resistance member 5, thereby avoiding the situation where the wind pressure resistance member 5 is loosely connected due to the rotation, and 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.

[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, an anti-wind pressure member 5 and a limiting member 6. Compared with the first embodiment, the difference of this embodiment is that the structure of the anti-wind pressure member 5 is different.

[0062] Specifically, Figure 5 As shown, a limiter 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 above-mentioned specific area). When the window sash fixing plate 2 rotates a preset angle relative to the window frame fixing plate 1, the limiter 6 abuts against the limiter 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, which passes through the limiter 6 and is connected to the window sash, so that the connecting member 5 forms a reinforcement point on the window sash fixing plate 2 close to the window frame side. When the window sash is subjected to wind pressure, it is not easy for misalignment shearing 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.

[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, an anti-wind pressure member 5 and a limiting member 6. Compared with the first embodiment, the difference of this embodiment is that the structure of the anti-wind pressure member 5 is different.

[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 Fig. 9 As shown, in the above embodiment, preferably, a threaded hole 63 is provided at the center of the stopper 6, and the bottom of the connecting column 5 has a threaded section 51, which is threadedly connected in the threaded hole 63 to movably connect the stopper 6 to the bottom of the connecting column 5. Therefore, stoppers 6 of different sizes 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 in detail here.

[0069] Sixth embodiment:

[0070] like Fig.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 a hinge structure 30 as described in any one of the second to fifth embodiments.
