[0040] Example 1

[0041] like Figure 1-10 As shown, an embodiment of the present invention provides an inward-tilted translation upper pulley hinge, which includes a bottom plate 1, a transmission rod 2, an additional rod 3 and a rocker arm 4;

[0042] The bottom plate 1 is used to be fixed on the fan body, one end of the additional rod 3 and one end of the rocker arm 4 are both hinged to the bottom plate 1, the other end of the additional rod 3 is slidably connected to the position of the rocker arm 4 near the middle, and the other end of the rocker arm 4 is used to be slidably connected to the frame, the transmission rod 2 is slidably connected to the bottom plate 1, and the transmission rod 2 has a transmission part 21 that abuts against the additional rod 3, so as to drive the additional rod 3 to rotate when the transmission rod 2 slides;

[0043] When the inwardly tilted translation upper pulley hinge is fully opened, the additional rod 3 is locked with the transmission rod 2 .

[0044] In this embodiment, the inward-tilt translation upper pulley hinge is used for doors and windows, which include a frame and a fan body arranged on the frame. The inward-tilt translation upper pulley hinge includes a base plate 1, a transmission rod 2, an additional rod 3 and a rocker arm 4.

[0045] When the cam 2 is in the closed position, the cam 2 is in the closed position, and the cam 2 is in the closed position, so that ...

[0046] In some embodiments, the additional rod 3 has a driving surface 31 that is shifted with the transmission part 21, the driving surface 31 abuts against the transmission rod 2, and a preset distance is formed between the first end and the second end of the driving surface 31 in a direction perpendicular to the transmission direction.

[0047] In this embodiment, the transmission part can be specifically a driving pin arranged on the transmission rod 2. The additional rod 3 has a driving surface 31 that cooperates with the transmission part 21. The driving surface 31 abuts against the transmission rod 2. There is a preset distance between the first end and the second end of the driving surface 31 in a direction perpendicular to the transmission direction. The transmission direction is the moving direction of the transmission rod 2. When the transmission rod 2 moves along the length of the base plate 1, the transmission part 21 abuts against the driving surface 31, so that the additional rod 3 can be rotated. The linear motion of the transmission rod 2 is converted into the rotational motion of the additional rod 3, which drives the rocker arm 4 to automatically rotate to realize the inner tilt of the fan body, thereby opening or closing the fan body.

[0048] The driving surface 31 can be an inclined surface, a curved surface, an arc surface, etc. (it can be circular facing either inside or outside).

[0049] In some embodiments, a locking groove 32 is constructed on the additional rod 3. In the transmission direction of the transmission rod 2, the locking groove 32 is arranged on one side of the driving surface 31. When the inwardly tilted upper pulley hinge is fully opened, the transmission part 21 is located in the locking groove 32.

[0050] In this embodiment, a locking groove 32 is constructed on the additional rod 3. In the transmission direction of the transmission rod 2, the locking groove 32 is arranged on one side of the driving surface 31. When the inward-tilted translational upper pulley hinge is fully opened, the transmission part 21 is located in the locking groove 32, so that the inward-tilted translational upper pulley hinge is self-locked after tilting inward, and the fan will not be closed due to external force or wind pressure, thereby improving the user experience.

[0051] In some embodiments, an avoidance notch 33 is further configured on the additional rod 3 . In the transmission direction of the transmission rod 2 , the avoidance notch 33 is located on a side of the driving surface 31 away from the locking groove 32 .

[0052] In this embodiment, an avoidance notch 33 is configured on the additional rod 3 to prevent the transmission part 21 from interfering with the additional rod 3, thereby ensuring that the inward-tilted translation upper pulley hinge can be closed.

[0053] In some embodiments, when the inward-tilted translational upper pulley hinge is opened, the driving surface 31, the locking groove 32 and the avoidance gap 33 are located on the side of the additional rod 3 facing the base plate 1. This structure can improve the structural compactness of the inward-tilted translational upper pulley hinge.

[0054] In some embodiments, the door and window further include a handle, which is rotatably disposed on the fan body and connected to the transmission rod 2. When the handle is rotated, the transmission rod 2 can drive the additional rod 3 to rotate.

[0055] In this embodiment, the transmission rod 2 is driven to move when the handle is rotated, and then the additional rod 3 is driven to rotate, so as to drive the rocker arm 4 to automatically rotate to realize the inner tilt of the fan body, thereby opening or closing the fan body. This structure is easy for users to operate and improves convenience.

[0056] In some embodiments, the transmission part 21 is located between the hinged joint between the additional rod 3 and the base plate 1 and the hinged joint between the rocker arm 4 and the base plate 1 .

[0057] In some embodiments, the hinge between the rocker arm 4 and the base plate 1 and the hinge between the additional rod 3 and the base plate 1 are arranged in sequence along the transmission direction; or, the hinge between the additional rod 3 and the base plate 1 and the hinge between the rocker arm 4 and the base plate 1 are arranged in sequence along the transmission direction.

[0058] Specifically, the transmission part 21 is located between the hinged part of the additional rod 3 and the bottom plate 1 and the hinged part of the rocker arm 4 and the bottom plate 1. The transmission part 21 is located at the hinged part of the additional rod 3 and the bottom plate 1, away from or close to the handle. Figure 1-Figure 5The transmission part 21 is shown to be located at the side of the hinge between the additional rod 3 and the base plate 1 away from the handle. Figure 6-Figure 10 As shown, the transmission part 21 is located at the side of the hinge between the additional rod 3 and the base plate 1 close to the handle.

[0060] In some embodiments, the locking groove 32 is located on a side of the driving surface 31 away from the handle.

[0061] In this embodiment, the locking groove 32 is located on the side of the driving surface 31 away from the handle, which can ensure that the inward-tilting upper pulley hinge is automatically tilted inward through the transmission rod and self-locks after tilting inward. The fan will not be closed due to external force or wind pressure, thereby improving the user experience.

[0062] In some embodiments, when the inward-tilted translation upper pulley hinge is opened, the transmission rod 2 is located on the side of the bottom plate 1 away from the additional rod 3, and the bottom plate 1 is provided with an avoidance groove 11 for the transmission part 21 to pass through.

[0063] In this embodiment, the avoidance grooves 11 are provided on the bottom plate 1 so that the transmission rods 2 and the additional rods 3 located on both sides of the bottom plate 1 can be connected via the transmission parts 21 .

[0064] In some embodiments, a slide groove 34 extending along the length direction is provided on the additional rod 3, and a sliding portion 41 located in the slide groove 34 is provided on the rocker arm 4. In this embodiment, the sliding portion 41 moves in the slide groove 34, so that the additional rod 3 and the rocker arm 4 are slidably connected, ensuring that the inward-tilted translation upper pulley hinge can be closed.

[0065] In some embodiments, the rocker arm 4 is provided with a pulley assembly 42 that slides with the frame. Specifically, a slideway is constructed on the frame, and the rocker arm 4 is provided with a pulley assembly 42 that slides with the slideway, thereby achieving a slidable connection between the rocker arm 4 and the frame.
