DETAILED DESCRIPTION

[0052] In order to enable those skilled in the art to more clearly understand the objectives, technical solutions and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0053] Reference Figures 1 to 3 , Figures 1 to 3The first embodiment of the hinge 10 of the present invention is shown. In the embodiment shown in the accompanying drawings, the hinge 10 includes a first hinge assembly 13 and a second hinge assembly 14, wherein the first hinge assembly 13 includes a first slide rail 111 fixed to the frame 30, a first support piece 121 fixed to the fan body 20, and a first connecting rod assembly 131 arranged between the first slide rail 111 and the first support piece 121, and the first connecting rod assembly 131 can slide along the first slide rail 111; the second hinge assembly 14 is located below the first hinge assembly 13, and the second hinge assembly 14 includes a second slide rail 112 fixed to the frame 30, a second support piece 122 fixed to the fan body 20, and a second connecting rod assembly arranged between the second slide rail 112 and the second support piece 122, and the second connecting rod assembly includes a third connecting rod 1411 and a fourth connecting rod 1412, and the two ends of the fourth connecting rod 1412 are respectively rotatably connected to the second connecting rod 111. The supporting piece 122 and the second slide rail 112, the two ends of the third connecting rod 1411 are respectively rotatably connected to the fourth connecting rod 1412 and the second slide rail 112, and the second slide rail 112 is provided with a movable slider 1414 slidably connected to the second slide rail 112 and a fixed block 1413 fixed to the second slide rail 112, and the third connecting rod 1411 and the fourth connecting rod 1412 are respectively rotatably connected to the fixed block 1413 and the movable slider 1414, and the first end of the third connecting rod 1411 is located above the movable slider 1414 to realize its rotatable connection with the second slide rail 112 (in this embodiment, the first end of the third connecting rod 1411 is rotatably connected to the fixed block 1413 fixed on the second slide rail 112, thereby indirectly rotatably connected to the second slide rail 112. In other embodiments, it can also be directly rotatably connected to the second slide rail 112). Preferably, the third connecting rod 1411 and the fixed block 1413 and the fourth connecting rod 1412, as well as the fourth connecting rod 1412 and the movable slider 1414 and the second supporting piece 122 are all connected in rotation via rivet shafts. Based on the above design, the sash 20 in the top-hung window can be opened at a large angle by the first hinge assembly 13 and the second hinge assembly 14, so as to solve the problem that the traditional hinged window cannot achieve a large opening angle. That is, when opening, the first connecting rod assembly 131 is driven to open and slide down by the gravity of the sash 20. At the same time, the second hinge assembly 14 for supporting the sash 20, which is arranged below the first hinge assembly 13, slides up, thereby providing a supporting force for the center of gravity of the sash 20, so that the sash 20 can overcome the gravity of the window sash and hover at any position. The sash 20 can also be fixed and supported. That is, when the user opens or closes the sash 20, the movable slider 1414 in the second hinge assembly 14 can move along the second slide rail 112 under the action of push or pull. During the movement, the center of gravity G of the sash 20 is as shown in FIG. Figure 4 As shown, it is almost maintained on a horizontal line, and the force on the fan body 20 is always balanced, which can overcome the gravity of the fan body 20 to achieve hovering at any position.

[0054] Specifically, if Figure 2 and Figure 3 As shown, in this embodiment, the first connecting rod assembly 131 includes a first connecting rod 1311, a second connecting rod 1312, and a slider 1313. The slider 1313 is slidably connected to the first slide rail 111. The ends of the first connecting rod 1311 and the second connecting rod 1312 are respectively rotatably connected to the slider 1313 and the first supporting plate 121. Preferably, in this embodiment, the slider 1313 is an integrated structure. Based on this design, the cooperation between the first connecting rod 1311 and the second connecting rod 1312, the slider 1313, and the first supporting plate 121 facilitates the wide-angle opening of the sash 20 in the top-hung window.

[0055] Furthermore, the hinge 10 also includes a fan fixing column 15, which is installed on the fan body 20, and one end of which is connected to the first connecting rod 1311 and the first supporting plate 121 through a rotating shaft 16. Specifically, in this embodiment, the rotating shaft 16 passes through the first connecting rod 1311 and the first supporting plate 121 in sequence and is connected to the fan fixing column 15.

[0056] Preferably, in this embodiment, the first slide rail 111 and the second slide rail 112 are integrally formed, forming a one-piece structure, while the first supporting piece 121 and the second supporting piece 122 are separate structures, respectively fixed to the upper end and the middle portion of the fan body 20. It is understood that in certain other embodiments, the first slide rail 111 and the second slide rail 112 may be separate structures, while the first supporting piece 121 and the second supporting piece 122 may be integrally formed, forming a one-piece structure.
