[0030] Please see Figures 1 to 4One embodiment of this application provides a hinge, which is particularly suitable for hinged connections between sash frames and fixed frames in curtain wall windows and other applications requiring high reliability.

[0031] Combination Figure 1 As shown in this application, the hinge includes: a fixing plate 1 for mounting and connecting with a fixing frame, a receiving plate 2 for mounting and connecting with a fan frame, a first swing arm 3 and a second swing arm 4 that are hinged to the fixing plate 1 and the receiving plate 2.

[0032] To avoid motion interference and ensure structural stability under stress, both the first swing arm 3 and the second swing arm 4 are long, flat plate structures.

[0033] In this application, one end of the first swing arm 3 is hinged to one end of the fixed plate 1, and the other end of the first swing arm 3 is hinged to the plate body of the receiving plate 2; one end of the second swing arm 4 is hinged to the plate body of the fixed plate 1, and the other end of the second swing arm 4 is hinged to one end of the receiving plate 2.

[0034] Combination Figure 1 and Figure 2 As shown, in order to avoid excessive friction between the first swing arm 3 and the second swing arm 4 and the fixed plate 1 during the opening and closing motion, and to avoid interference from fasteners such as screws, in this embodiment, the fixed plate 1 is fixedly provided with a first pressing member 5 and a second pressing member 6. The first pressing member 5 is fitted between the first swing arm 3 and the fixed plate 1, and the second pressing member 6 is fitted between the second swing arm 4 and the fixed plate 1.

[0035] Combination Figure 2 As shown, in order to improve the support effect on the first swing arm 3, in this embodiment, the first pressing member 5 is a flat plate structure, and the first pressing member 5 extends along the direction when the first swing arm 3 is retracted into the fixed plate 1 to form a reinforcing part 51.

[0036] Combination Figure 2 As shown, the second pressing member 6 has a flat plate structure, and the second pressing member 6 extends along the orientation of the second swing arm 4 when it is retracted into the fixed plate 1 to form an extension portion 61.

[0037] Combination Figure 2 As shown, in this embodiment, the first pressing member 5 is fixed to the fixing plate 1 by the first fastening screw 52; the second pressing member 6 is fixed to the fixing plate 1 by the second fastening screw 62 and the third fastening screw 63, with the third fastening screw 63 located in the extension 61. The distribution of the various fastening screws satisfies the tension requirements of the hinge; furthermore, the third fastening screw 63 securely connects the extension 61 and the fixing plate 1, improving the stability of the second pressing member 6.

[0038] Furthermore, in order to improve the installation stability of the first pressing member 5 and the second pressing member 6, rivets 85 can be used to reinforce their installation connection with the fixing plate 1.

[0039] Combination Figure 1 and Figure 2 As shown in this application, the second pressing member 6 is fixedly provided with a positioning member 7 for limiting the maximum extension range of the second swing arm 4. The positioning member 7 is located on the side facing the first swing arm 3 at the end of the second swing arm 4 that is hinged to the fixed plate 1.

[0040] Combination Figure 3 and Figure 4 As shown, in this embodiment, a retraction positioning surface 71 is formed on one side of the positioning member 7 for abutting against the first swing arm 3 when the hinge is retracted.

[0041] Combination Figure 4 As shown, when the hinge is closed, the first swing arm 3 and the second swing arm 4 drive the receiving plate 2 to close onto the fixed plate 1, and the closing positioning surface 71 of the positioning member 7 can abut against the first swing arm 3.

[0042] Combination Figure 3 As shown in this application, one end of the first swing arm 3 is provided with a bent head 31, which is hinged to the fixed plate 1; the arm body of the second swing arm 4 has a bent portion 41.

[0043] By combining the bend head 31 and the bending part 41, the first swing arm 3 and the second swing arm 4 can overlap more with the fixed plate 1 when the hinge is closed, thus reducing the size of the hinge structure.

[0044] Combination Figure 1 and Figure 3 As shown in this application, the bent head 31 of the first swing arm 3 is hinged to the fixed plate 1 by the first pin 81, and the other end of the first swing arm 3 is hinged to the receiving plate 2 by the third pin 83; one end of the second swing arm 4 is hinged to the fixed plate 1 by the second pin 82, and the other end of the second swing arm 4 is hinged to the receiving plate 2 by the fourth pin 84.

[0045] Combination Figure 2 As shown, to facilitate pin fixing, the first pressing member 5 is provided with a first pin hole 53 for the first pin 81 to pass through, and the second pressing member 6 is provided with a second pin hole 64 for the second pin 82 to pass through. Correspondingly, the receiving plate 2 is also provided with pin holes (not shown in the figure) for the third pin 83 and the fourth pin 84 to pass through.

[0046] In this application, the virtual connection line between the first pin 81 and the third pin 83 is located within the edge of the arm body of the first swing arm 3; the virtual connection line between the second pin 82 and the fourth pin 84 is located within the edge of the arm body of the second swing arm 4.

[0047] Combination Figure 1 and Figure 2As shown, in order to facilitate the installation of the fixing plate 1 and the receiving plate 2, the fixing plate 1 is provided with a number of fixing holes 11 for fastening screws to pass through, and the receiving plate 2 is provided with a number of mounting holes 22 for fastening screws to pass through.

[0048] In this application, the fixing plate 1 is installed on the fixing frame using common installation methods (such as bolt connection), and the receiving plate 2 is installed on the fan frame using a corresponding installation structure. The first swing arm 3 and the second swing arm 4 are hinged to the fixing plate 1 and the receiving plate 2 respectively, and each pin (first pin 81, second pin 82, third pin 83 and fourth pin 84) passes through the corresponding pin hole to achieve a stable hinged relationship.

[0049] Furthermore, the first pressing member 5 is fixed to the fixed plate 1 by the first fastening nail 52, ensuring a tight fit with the first swing arm 3. When the first swing arm 3 is retracted into the fixed plate 1, its reinforcing part 51 can effectively disperse stress and strengthen the structure. The second pressing member 6 is fixed to the fixed plate 1 by the second fastening nail 62 and the third fastening nail 63. The third fastening nail 63 is located in the extension part 61. When the second swing arm 4 is retracted, the extension part 61 can also play a similar role. Moreover, the positioning member 7 accurately limits the maximum extension range of the second swing arm 4. When the hinge is retracted, the retraction positioning surface 71 can abut against the first swing arm 3 to achieve accurate positioning.

[0050] Combination Figure 1 As shown, in order to make the hinge and the fan frame more stable and reliable in installation, a connecting plate 21 is provided at one end of the receiving plate 2 perpendicular to the receiving plate 2.

[0051] In this application, when the fan frame unfolds or retracts relative to the fixed frame around the hinge, the first swing arm 3 and the second swing arm 4 rotate around their respective hinge points.

[0052] Because the virtual connection lines of the first pin 81 and the third pin 83 are located within the edge of the first swing arm 3, and the virtual connection lines of the second pin 82 and the fourth pin 84 are located within the edge of the second swing arm 4, this structural design makes the swing arms more stable during movement, reducing the possibility of swaying and deformation. Moreover, when the fan frame is opened, the improved design of the virtual connection lines enhances the load-bearing capacity of the first swing arm 3 and the second swing arm 4, preventing excessive stress on the swing arms and thus bending deformation, thereby increasing their service life.

[0053] Meanwhile, the vertically arranged connecting plate 21 on the receiving plate 2 facilitates connection and installation with the fan frame, and can effectively transmit force when the overall structure is under stress, ensuring the stability of the entire hinge structure.

[0054] The hinges provided in the embodiments of this application have been described in detail above. Specific embodiments have been used to explain the principles and implementation methods of this application. The above description is only for the purpose of helping to understand the method and core mechanism of this application. At the same time, for those skilled in the art, there will be changes in specific embodiments and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
