[0037] Please refer to Figures 1 to 3 The application provides a desktop fan assembly 100, which comprises a fixed part 10 and a movable part 20.

[0038] The fixed part 10 is indirectly fixed on the base 60 through the mounting bracket 30 which will be introduced below, and the movable part 20 is fixed with the fan body 200 which will be introduced below.

One of the fixed part 10 and the movable part 20 is provided with a sliding rail 21, and the other of the fixed part 10 and the movable part 20 is provided with a sliding piece 11 matched with the sliding rail 21 with damping, so that the concave spherical surface 201 and the convex spherical surface 101 can relatively rotate along the up-down direction.

[0041] It should be noted that, due to the constraint of the sliding piece 11 and the sliding rail 21 on the concave spherical surface 201 and the convex spherical surface 101, the concave spherical surface 201 and the convex spherical surface 101 can only relatively rotate along the up-down direction, and cannot relatively rotate along the horizontal direction and other directions, thereby ensuring that the movable part 20 can adjust the pitch angle.

[0042] In this embodiment, the fixed part 10 is provided with a convex spherical surface 101 and a sliding member 11, and the movable part 20 is provided with a concave spherical surface 201 and a sliding rail 21. When the convex spherical surface 101 and the concave spherical surface 201 are matched, the sliding member 11 can be inserted into the sliding rail 21. When the convex spherical surface 101 and the concave spherical surface 201 are disengaged, the sliding member 11 can be pulled out of the sliding rail 21. In this way, the movable part 20 and the fixed part 10 can be easily disassembled. In other embodiments, the fixed part 10 can be provided with a convex spherical surface 101 and a sliding rail 21, and the movable part 20 can be provided with a concave spherical surface 201 and a sliding member 11. Alternatively, the fixed part 10 can be provided with a concave spherical surface 201 and a sliding rail 21, and the movable part 20 can be provided with a convex spherical surface 101 and a sliding member 11.

[0043] Preferably, the sliding rail 21 is formed by partially penetrating the movable part 20. In this way, the sliding rail 21 can be easily formed, and the sliding member 11 and the fixed part 10 can be integrally formed. In this way, the connection strength of the sliding member 11 and the fixed part 10 can be enhanced. In addition, the sliding member 11 and the fixed part 10 can be fixed by the fixed connection or detachable connection described above.

[0044] Further, the side of the fixed part 10 opposite to the convex spherical surface 101 is provided with a concave spherical surface, and the side of the movable part 20 opposite to the concave spherical surface 201 is provided with a convex spherical surface. In this way, the fixed part 10 and the movable part 20 can be easily formed by machining methods such as die casting and mold forming. In addition, please refer to Figure 2 The side of the movable part 20 opposite to the fixed part 10 is provided with a receiving groove 202, and the receiving groove 202 is provided with a plurality of longitudinal and transverse intersecting reinforcing rib plates 22. In this way, the structural strength of the fixed part 10 can be enhanced.

[0045] Specifically, the sliding rail 21 and the sliding member 11 are both provided with two, and the two sliding rails 21 are respectively arranged on the left and right sides of the concave spherical surface 201, and the two sliding members 11 are respectively arranged on the left and right sides of the convex spherical surface 101. In this way, the stability of the movable part 20 during the pitch angle adjustment can be enhanced. In other embodiments, the sliding rail 21 and the sliding member 11 can also be provided with one or three, four or other values.

[0046] It is worth noting that when the sliding rail 21 and the sliding member 11 are both one, the sliding rail 21 and the sliding member 11 are in damping sliding cooperation.

[0047] By the technical solutions, the concave spherical surface 201 and the convex spherical surface 101 are relatively rotatable in the up-down direction, and the movable part 20 can be adjusted in the pitch angle relative to the fixed part 10, so that the pitch angle of the desktop fan 1000 can be adjusted. Because the sliding rail 21 and the sliding part 11 are in the sliding fit with damping, the sliding part 11 can be fixed to the sliding rail 21 when sliding to any position of the sliding rail 21, and the movable part 20 can be fixed to the fixed part 10 when rotating to a target pitch angle, so that the desktop fan 1000 can be fixed when rotating to the target pitch angle.

In this way, when the sliding part 11 slides along the sliding rail 21, the damping part 12 is always in interference abutment with the inner wall in the width direction of the sliding rail 21, so that the sliding fit with damping between the sliding part 11 and the sliding rail 21 is realized. Moreover, because the damping part 12 is detachably connected with the sliding part 11, the damping part 12 can be maintained or replaced when the damping part 12 is worn or damaged.

[0049] In this embodiment, the sliding part 11 and the damping part 12 are one-to-one arranged. In this way, when the damping part 12 is maintained or replaced, only one damping part 12 needs to be maintained or replaced. In other embodiments, the sliding part 11 and the damping part 12 can also be one-to-many arranged, that is, the sliding part 11 is detachably connected with multiple damping parts 12.

In this way, when installing the damping member 12, the damping member 12 is inserted into the slot 111 through the slot of the slot 111, and at the same time, another portion of the damping member 12 is inserted into the communication port 112 and abuts against the inner wall of the sliding rail 21 in the width direction, so that the installation of the damping member 12 is completed. When disassembling the damping member 12, the damping member 12 is pried out of the slot 111 and the communication port 112 using a tool, so that the disassembly of the damping member 12 is completed.
