[0027] Furthermore, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure as shown in the attached drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the structure.

[0028] Please see Figures 1 to 5 This application provides a windproof hinge suitable for doors and windows, especially for hinged windows. Generally, a window includes a fixed frame fixed to a wall and a sash frame with glass installed. The windproof hinge of this application is used to hinge the fixed frame and the sash frame.

[0029] Combination Figure 1 and Figure 2As shown, in one embodiment, the windproof hinge includes a fixing plate 100 for mounting and connecting to a fixing frame, a support plate 200 for mounting and connecting to a fan frame, and a connecting arm assembly 300 connecting the fixing plate 100 and the support plate 200.

[0030] The fixed plate 100 is provided with a groove 101, and a sliding block 102 is slidably disposed in the groove 101. The fixed plate 100 includes a stop portion 103 for limiting the movement position of the sliding block 102. The connecting arm assembly 300 includes a sliding end 301, a hinge end 340 and a swing end 350. The sliding end 301 is hinged to the sliding block 102 to slide with the sliding block 102. The hinge end 340 is hinged to the fixed plate 100 and the swing end 350 is hinged to the support plate 200.

[0031] In use, for example, when this windproof hinge is used in windows of high-rise buildings, the fixing plate 100 can be assembled and fixed to the fixing frame, and the support plate 200 can be installed and fixed to the sash frame. When the window is opened or closed, the support plate 200 moves relative to the fixing plate 100 through the cooperation of the connecting arm assembly 300, and the sliding end 301 of the connecting arm assembly 300 slides under the cooperation of the sliding groove 101 and the sliding block 102. When the window is in the fully open state, the abutment 103 of the fixing plate 100 forms an abutment and limiting effect on the sliding block 102, providing a reliable abutment effect even in strong winds, and playing a role in resisting strong winds and preventing deformation.

[0032] Combination Figure 3 As shown, in order to make the slide groove 101 structure more reliable and to facilitate processing and production, in this embodiment, a long groove member 110 is fixedly provided on the fixing plate 100, and the long groove member 110 is provided with the slide groove 101, which is arranged along the length direction of the fixing plate 100.

[0033] Specifically, the long slotted part 110 can be fixed to the fixing plate 100 by means of riveting, welding or screwing.

[0034] In other embodiments, the groove 101 can also be directly machined onto the fixed plate 100.

[0035] Combination Figure 3 and Figure 4 As shown, in order to facilitate production and improve structural reliability, in this embodiment, a reinforcing member 120 is fixedly provided on the fixing plate 100. One end of the reinforcing member 120 protrudes upward to provide a stop portion 103, which abuts against one end of the sliding groove 101.

[0036] Specifically, the abutment 103 can be formed by bending one end of the reinforcing member 120, in which case the abutment 103 and the reinforcing member 120 are integrally formed, which is convenient for processing. Moreover, since the abutment 103 is formed by the reinforcing member 120, when the abutment 103 is damaged, it can be repaired by replacing the reinforcing member 120, which is convenient for maintenance and can improve the service life of the windproof hinge.

[0037] The reinforcing member 120 can be installed on the fixing plate 100 by means of riveting, screwing, etc.

[0038] Combination Figure 2 As shown, in this embodiment, the sliding block 102 is rotatably provided with an adjusting bolt 104, which extends downward from the upper surface of the sliding block 102 to the surface of the slide groove 101.

[0039] The tension of the hinge can be flexibly adjusted by adjusting the setting of the adjusting bolt 104. The bottom of the adjusting bolt 104 is set as a flat structure, which makes contact with the surface of the slide groove 101. When it is necessary to adjust the opening and closing tension of the windproof hinge, the adjusting bolt 104 can be turned to adjust the contact force between it and the slide groove 101, and the tension can be adjusted by changing the friction force.

[0040] For ease of adjustment, the head of the adjusting screw can be designed as a large round part that is easy to turn by hand, so that the tightness can be adjusted without the need for tools.

[0041] Combination Figure 2 and Figure 3 As shown, in order to prevent the sliding block 102 from moving too far and becoming loose, in this embodiment, the fixing plate 100 is fixedly provided with a plug 130, which abuts against the other end of the sliding groove 101 away from the abutment 103.

[0042] In this application, the plug 130 is located at the end of the fixing plate 100, and the abutment 103 is located in the middle region of the fixing plate 100.

[0043] Combination Figure 3 and Figure 5 As shown, in this embodiment, the fixing plate 100 is provided with a pad 140, and one side edge of the pad 140 extends and protrudes beyond the edge of the fixing plate 100.

[0044] By setting the pad 140, not only can the structural strength be improved, but its protruding edge of the fixing plate 100 can also cooperate with the structure of the fixing frame to increase the supporting force of the windproof hinge.

[0045] Combination Figure 3 and Figure 4As shown, in this embodiment, the connecting arm assembly 300 includes a first connecting arm 310, a second connecting arm 320, and a third connecting arm 330. The first connecting arm 310 includes a sliding end 301 and a first swinging end 302. The second connecting arm 320 includes a first hinge end 303 and a connecting end 304. The third connecting arm 330 includes a second hinge end 305 and a second swinging end 306. The first hinge end 303 and the second hinge end 305 are respectively hinged to the fixed plate 100. The first swinging end 302 and the second swinging end 306 are respectively hinged to the support plate 200. The connecting end 304 is hinged to the arm body of the first connecting arm 310.

[0046] By connecting and cooperating with each link, the support plate 200 can swing relative to the fixed plate 100. Specifically, each link can be hinged using parts such as pins.

[0047] In this embodiment, in order to improve the structural strength and load-bearing capacity of the windproof hinge, the pad 140 and the reinforcing member 120 are stacked on the fixing plate 100 in sequence, and the pad 140, the reinforcing member 120 and the fixing plate 100 are firmly connected by the reinforcing screws 307.

[0048] The first hinge end 303 and the second hinge end 305 of the connecting arm assembly 300 are both located on the upper surface of the pad 140, and are hinged to the pad 140, the reinforcing member 120 and the fixing plate 100 through components such as pins.

[0049] To improve the load-bearing capacity of the windproof hinge, at least two reinforcing screws 307 can be used to fix the pad 140, the reinforcing member 120 and the fixing plate 100 to the fixing frame. Moreover, the reinforcing screws 307 can be set on the side of the hinge end to improve the firmness.

[0050] To improve the overall wind resistance performance, the first connecting arm 310, the second connecting arm 320 and the third connecting arm 330 may be provided with protruding reinforcing parts 308 at the arm body to improve structural strength and cope with strong winds.

[0051] Combination Figure 6 As shown, in one embodiment, a reinforcing portion 308 is provided protruding from the arm body of the third connecting arm 330.
