[0040] Example 1

[0041] like Figure 1-10As shown, this utility model embodiment provides an inward-tilting and translating upper pulley hinge, which includes a base plate 1, a transmission rod 2, an additional rod 3, and a rocker arm 4;

[0042] The base plate 1 is used to fix it to the fan body. One end of the auxiliary rod 3 and one end of the rocker arm 4 are both hinged to the base plate 1. The other end of the auxiliary rod 3 is slidably connected to the rocker arm 4 near the middle. The other end of the rocker arm 4 is slidably connected to the frame. The transmission rod 2 is slidably connected to the base plate 1, and the transmission rod 2 has a transmission part 21 that abuts against the auxiliary rod 3 so as to drive the auxiliary rod 3 to rotate when the transmission rod 2 slides.

[0043] When the inward-tilting upper pulley hinge is fully open, the additional rod 3 locks with the transmission rod 2.

[0044] In this embodiment, the inward sliding upper pulley hinge is used for doors and windows. The doors and windows include a frame and a sash set on the frame. The inward sliding upper pulley hinge includes a base plate 1, a transmission rod 2, an additional rod 3, and a rocker arm 4.

[0045] In this embodiment, the base plate 1 is set on the fan body. One end of the auxiliary rod 3 and one end of the rocker arm 4 are both hinged to the base plate 1. The other end of the auxiliary rod 3 is slidably connected to the rocker arm 4 near the middle. The rocker arm 4 is slidably connected to the frame. The transmission rod 2 is slidably connected to the base plate 1. The transmission part 21, which abuts against the auxiliary rod 3, can drive the auxiliary rod 3 to rotate when the transmission part 21 slides. The rotation of the auxiliary rod 3 can drive the rocker arm 4 to swing. The linear motion of the transmission rod 2 is converted into the rotational motion of the auxiliary rod 3, which drives the rocker arm 4 to rotate automatically to realize the fan body tilting inward, thereby opening or closing the fan body. When the tilting and translational upper pulley hinge is open, that is, when the fan body is opened, since the auxiliary rod 3 is locked with the transmission rod 2, the tilting and translational upper pulley hinge in this embodiment realizes automatic tilting inward through the transmission part 21 of the transmission rod 2. After tilting inward, it is self-locking and will not cause the fan to close due to external force or wind pressure, thus improving the user experience.

[0046] In some embodiments, the auxiliary rod 3 has a driving surface 31 that engages with the transmission part 21. The driving surface 31 abuts against the transmission rod 2, and 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.

[0047] In this embodiment, the transmission part can specifically be a drive pin set on the transmission rod 2. The auxiliary rod 3 has a drive surface 31 that cooperates with the transmission part 21. The drive surface 31 abuts against the transmission rod 2. There is a preset distance between the first end and the second end of the drive surface 31 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, since the transmission part 21 abuts against the drive surface 31, the auxiliary rod 3 can rotate. The linear motion of the transmission rod 2 is converted into the rotational motion of the auxiliary rod 3, which drives the rocker arm 4 to rotate automatically to realize the fan body tilting inward, thereby opening or closing the fan body.

[0048] The driving surface 31 can be an inclined surface, a curved surface, an arc surface, etc. (circular surfaces can be inward or outward).

[0049] In some embodiments, the additional rod 3 is provided with a locking groove 32. In the transmission direction of the transmission rod 2, the locking groove 32 is provided on one side of the drive surface 31. When the inward translational upper pulley hinge is fully open, the transmission part 21 is located in the locking groove 32.

[0050] In this embodiment, by constructing a locking groove 32 on the additional rod 3, the locking groove 32 is located on one side of the drive surface 31 in the transmission direction of the transmission rod 2. When the inward sliding upper pulley hinge is fully open, the transmission part 21 is located in the locking groove 32, realizing the self-locking of the inward sliding upper pulley hinge after it is tilted inward, so that the fan will not be closed due to external force or wind pressure, thus improving the user experience.

[0051] In some embodiments, the additional rod 3 is also provided with a clearance notch 33, which is located on the side of the drive surface 31 away from the locking groove 32 in the transmission direction of the transmission rod 2.

[0052] In this embodiment, by constructing an avoidance notch 33 on the additional rod 3, interference between the transmission part 21 and the additional rod 3 is prevented, ensuring that the inward translational upper pulley hinge can be closed.

[0053] In some embodiments, when the inward-tilting upper pulley hinge is open, the drive surface 31, the locking groove 32, and the clearance notch 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-tilting upper pulley hinge.

[0054] In some embodiments, the door and window also include a handle, which is rotatably mounted on the sash and connected to the transmission rod 2. When the handle rotates, it can drive the transmission rod 2 to drive the auxiliary rod 3 to rotate.

[0055] In this embodiment, the transmission rod 2 is driven to move when the handle is rotated, which in turn drives the auxiliary rod 3 to rotate, thereby causing the rocker arm 4 to rotate automatically to tilt the fan body inward, thus opening or closing the fan body. This structure is easy for users to operate and improves convenience.

[0056] In some embodiments, the transmission unit 21 is located between the hinge point of the auxiliary rod 3 and the base plate 1 and the hinge point of the rocker arm 4 and the base plate 1.

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

[0058] Specifically, the transmission unit 21 is located between the hinge point of the auxiliary rod 3 and the base plate 1 and the hinge point of the rocker arm 4 and the base plate 1. The transmission unit 21 is located on the side of the auxiliary rod 3 and the base plate 1 that is away from or close to the handle. Figures 1-5 The transmission unit 21 is located on the side away from the handle at the hinge point between the auxiliary rod 3 and the base plate 1. Figures 6-10 The transmission unit 21 is located near the handle at the hinge point between the auxiliary rod 3 and the base plate 1.

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

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

[0062] In some embodiments, when the inward-tilting upper pulley hinge is opened, the transmission rod 2 is located on the side of the base plate 1 away from the auxiliary rod 3, and the base plate 1 has a clearance groove 11 for the transmission part 21 to pass through.

[0063] In this embodiment, by opening a clearance groove 11 on the base plate 1, the transmission rod 2 and the auxiliary rod 3 located on both sides of the base plate 1 can be connected through the transmission part 21.

[0064] In some embodiments, the additional rod 3 is provided with a groove 34 extending along the length direction, and the rocker arm 4 is provided with a sliding part 41 located in the groove 34. In this embodiment, the additional rod 3 and the rocker arm 4 are slidably connected by the sliding part 41 moving in the groove 34, ensuring that the inward 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, the frame is constructed with a slide rail, and the rocker arm 4 is provided with a pulley assembly 42 that slides with the slide rail, so that the rocker arm 4 and the frame are slidably connected.
