[0040] It should be explained that an upper hinge of an embodiment of the utility model can be switched to a state in which the first connecting rod 110 is open relative to the fixed rod 100, a state in which the installation rod 130 is open relative to the first connecting rod 110, and a closed state. When the first connecting rod 110 is open relative to the fixed rod 100, the window sash swings in one direction toward the room to open the window. When the installation rod 130 is open relative to the first connecting rod 110, the window sash swings in another direction toward the room to open the window.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As for the fixing rod 100, the fixing rod 100 is used to be installed on the window frame, so that the upper hinge can be fixed on the window frame.

[0042] For the first support assembly 120, the first support assembly 120 is connected between the fixed rod 100 and the first connecting rod 110. The first support assembly 120 is used to support the first connecting rod 110 to swing in one direction, so that the first connecting rod 110 can drive the window sash to swing in one direction to open the window, thereby realizing the window opening and closing function of the upper hinge.

[0043] In some specific embodiments, the first support assembly 120 includes a second support rod 300, one end of the second support rod 300 is hinged to the first connecting rod 110, and the other end of the second support rod 300 is slidably connected to the fixed rod 100, so that the second support rod 300 can support the movement of the first connecting rod 110, thereby making the first connecting rod 110 more stable.

[0044] In some specific embodiments, the first support assembly 120 also includes a third support rod 310 and a fourth support rod 320, one end of the third support rod 310 is hinged to the fixed rod 100, the other end of the third support rod 310 is hinged to one end of the fourth support rod 320, and the other end of the fourth support rod 320 is hinged to the first connecting rod 110, so that, on the one hand, the third support rod 310 and the fourth support rod 320 can strengthen the support for the first connecting rod 110, making the first connecting rod 110 more stable, and on the other hand, the second support rod 300, the third support rod 310 and the fourth support rod 320 can cooperate to guide the swing of the first connecting rod 110, so that the swing direction of the first connecting rod 110 remains stable.

[0045] Furthermore, the second supporting rod 300 is hinged to the third supporting rod 310 , thereby further limiting the swinging direction of the first connecting rod 110 .

[0046] As for the mounting rod 130 , the mounting rod 130 is used to mount the window sash.

[0047] As for the second supporting assembly 140 , the second supporting assembly 140 connects the first connecting rod 110 and the mounting rod 130 , and the second supporting assembly 140 is used to support the mounting rod 130 to swing in another direction.

[0048] In this embodiment, a mounting rod 130 and a second support assembly 140 are provided. The mounting rod 130 is used to install the window sash. The second support assembly 140 connects the first connecting rod 110 and the mounting rod 130. The second support assembly 140 is used to support the mounting rod 130 to swing in another direction, so that the mounting rod 130 can swing relative to the first connecting rod 110, which makes it convenient for the mounting rod 130 to drive the window sash to swing in one direction, thereby diversifying the opening angles of the window sash.

[0049] Reference Figure 5In some specific embodiments, the second supporting assembly 140 includes a first slider 250 and a first supporting rod 260, the mounting rod 130 has a first slide groove 270, and the first slide groove 270 is extended along the length direction of the mounting rod 130. The first slider 250 is slidably set in the first slide groove 270, and the end of the first connecting rod 110 away from the fixed rod 100 is hinged to the first slider 250, and the two ends of the first supporting rod 260 are respectively hinged to the first connecting rod 110 and the mounting rod 130. Therefore, on the one hand, the first supporting rod 260 can support the movement of the mounting rod 130, so that the swing of the mounting rod 130 is more stable. On the other hand, the first slider 250 and the first supporting rod 260 can cooperate to guide the swing direction of the mounting rod 130, so that the swing direction of the mounting rod 130 remains stable.

[0050] Furthermore, the top of the first slide groove 270 has an inner convex edge 280, and the bottom of the first slider 250 has an outer convex edge 290. The inner convex edge 280 and the outer convex edge 290 cooperate with each other for upper and lower limit, and the first connecting rod 110 is hinged to the top of the first slider 250, so that the inner convex edge 280 and the outer convex edge 290 cooperate to prevent the first slider 250 from detaching from the first slide groove 270.

[0051] Reference Figure 7 , Figure 8 and Fig. 9 In some specific embodiments, the mounting rod 130 is rotatably provided with a first adjusting pin 150, the first adjusting pin 150 has a first eccentric head 160, the first connecting rod 110 is provided with a limiting protrusion 170, and the first eccentric head 160 abuts against the inner side of the limiting protrusion 170 for limiting.

[0052] It can be understood that the first eccentric head 160 abuts against the inner side of the limiting protrusion 170 to limit the position, so that when the window is closed, the limiting protrusion 170 can limit the mounting rod 130 from swinging toward the outdoor side, which is convenient for locking the window. In addition, by rotating the first adjusting nail 150, the first adjusting nail 150 drives different positions of the first eccentric head 160 to abut against the limiting protrusion 170 when rotating, and changes the distance from the abutment position of the first eccentric head and the limiting protrusion 170 to the rotation axis of the first adjusting nail 150, thereby offsetting the gap between the mounting rod 130 and the first connecting rod 110 when the window is closed, and then making the window sash more secure after closing the window.

[0053] In some specific embodiments, the first adjusting pin 150 and the mounting rod 130 are frictionally engaged to stop rotation, and the top of the first adjusting pin 150 has a first adjusting groove 180. It can be understood that the abutment and friction between the first adjusting pin 150 and the mounting rod 130 makes the friction force generated between the first adjusting pin 150 and the mounting rod 130 prevent the first adjusting pin 150 from rotating relative to the mounting rod 130, thereby ensuring that the first adjusting pin 150 can remain stable when the first eccentric head 160 and the limiting protrusion 170 are abutted and limited. In addition, the top of the first adjusting pin 150 has a first adjusting groove 180, and the first adjusting groove 180 can accommodate tools such as hex keys to facilitate the rotation and adjustment of the first adjusting pin 150.

[0054] It should be explained that the upper hinge of the present embodiment can only rotate and adjust the first adjustment pin 150 when the mounting rod 130 is in an open state relative to the first connecting rod 110 .

[0055] In some specific embodiments, a first sliding rod 190 is slidably provided on the mounting rod 130, a first limiting pin 200 is provided on the first sliding rod 190, a first limiting seat 210 is provided on the first connecting rod 110, and the bottom of the first limiting seat 210 has a U-shaped groove 220 with an open bottom, and the notch of the U-shaped groove 220 is located on one side of the U-shaped groove 220 along the length direction of the first connecting rod 110, and the first sliding rod 190 slides to drive the first limiting pin 200 in and out of the U-shaped groove 220, and the first limiting pin 200 cooperates with the U-shaped groove 220 for limiting.

[0056] It can be understood that when the window sash only needs to be opened in one direction, the first slide bar 190 can be slid so that the first slide bar 190 drives the first limit pin 200 to enter the U-shaped groove 220, so that the first limit pin 200 and the U-shaped groove 220 cooperate to limit and prevent the mounting rod 130 from swinging relative to the first connecting rod 110, thereby preventing the window sash from swinging in another direction. When the window sash needs to be opened in another direction, the first slide bar 190 can be slid in the opposite direction so that the first slide bar 190 drives the first limit pin 200 to disengage from the U-shaped groove 220, thereby quickly releasing the U-shaped groove 220 from limiting the mounting rod 130.

[0057] In some specific embodiments, the first limit pin 200 is rotatably connected to the first sliding rod 190, and the first limit pin 200 has a second eccentric head 230, and the second eccentric head 230 cooperates with the U-shaped groove 220 to limit the position. Therefore, by rotating and adjusting the first limit pin 200, the second eccentric head 230 and the U-shaped groove 220 can cooperate to change the relative fixed position of the first connecting rod 110 and the mounting rod 130, thereby facilitating the elimination of the gap between the first connecting rod 110 and the mounting rod 130.

[0058] Furthermore, the first limiting nail 200 and the first sliding rod 190 are frictionally matched to prevent rotation, and a second adjustment groove 240 is formed on the top of the first limiting nail 200 .

[0059] It can be understood that the abutment friction between the first limit pin 200 and the first slide bar 190 makes the friction force generated between the first limit pin 200 and the first slide bar 190 prevent the first limit pin 200 from rotating relative to the first slide bar 190, thereby ensuring that the first limit pin 200 can remain stable when the second eccentric head 230 and the U-shaped groove 220 are abutted for limiting. In addition, the top of the first limit pin 200 has a second adjustment groove 240, and the second adjustment groove 240 can accommodate tools such as hex keys to facilitate the rotation and adjustment of the first limit pin 200.

[0060] It should be explained that the upper hinge of the present embodiment can only rotate and adjust the first limiting pin 200 when the mounting rod 130 is in an open state relative to the first connecting rod 110 .
