[0026] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0027] Please also read Figure 1-Figure 4 , this embodiment provides a fan installation device, including a wall fixing frame 1, a base plate assembly 2, a mounting assembly 3, a rotating assembly 4 and a limiting assembly 5;

[0028] The base plate assembly 2 is arranged on the wall fixing frame 1, and a slide groove 211 is provided on the base plate assembly 2. A long hole 212 is provided at the bottom of the slide groove 211. The installation assembly 3 can be slidably placed in the slide groove 211 and pass through the long hole 212; a limit plate 23 is also provided in the slide groove 211, and can be inserted into the installation assembly 3 after the installation assembly 3 slides, so as to limit the lifting of the installation assembly 3; specifically, a mounting hole 11 is provided on the wall fixing frame 1, which is used to fix it on the wall; the fan is installed and fixed on the installation assembly 3, and after the installation assembly 3 is placed on the slide groove 211, the limit plate 23 can be inserted into the installation assembly 3 by sliding to prevent it from lifting. When the installation assembly 3 is away from the limit plate 23, it can leave the base plate assembly 2 by lifting.

[0029] The rotating assembly 4 is rotatably connected to the bottom plate assembly 2, and the sliding of the mounting assembly 3 can drive the rotating assembly 4 to rotate; the limiting assembly 5 is rotatably connected to the bottom plate assembly 2, and the limiting assembly 5 can limit the rotation of the rotating assembly 4. It should be understood that the sliding of the mounting assembly 3 drives the rotating assembly 4 to rotate, and the rotation of the rotating assembly 4 can drive the sliding of the mounting assembly 3. When the limiting assembly 5 limits the rotation of the rotating assembly 4, it limits the sliding of the mounting assembly 3. In the initial state, the limiting assembly 5 abuts against the rotating assembly 4 to limit the rotation of the rotating assembly 4; after the limiting assembly 5 is away from the rotating assembly 4, the rotating assembly 4 can rotate.

[0030] The present application adjusts the angle of the limiting component to make it close to or away from the rotating component 4, so as to fix the position of the installation component 3, that is, the fan. When it is necessary to slide the installation component 3 to change the position of the fan, it is only necessary to rotate the limiting component 5 away from the rotating component 4 to slide the installation component 3. After reaching the desired position, the limiting component 5 is rotated in the opposite direction to limit the rotation of the rotating component 4 again.

[0031] In other schemes, the base plate assembly 2 includes a base plate body 21 and a connecting plate 22; the base plate body 21 is connected to the wall fixing frame 1, a slide groove 211 is provided on the base plate body 21, two connecting plates 22 are provided, and are respectively arranged on the bottom surface of the base plate body 21 opposite to each other, and the rotating assembly 4 and the limiting assembly 5 are respectively rotatably connected to the connecting plate 22.

[0032] In other schemes, the mounting assembly 3 includes a mounting plate 31, a slider 32 and a rack 33; a slider 32 is provided at the bottom of the mounting plate 31, and the slider 32 is slidably placed in the slide groove 211, and the two opposite sides of the slider 32 respectively abut the sides of the slide groove 211; the limiting plate 23 is located in the slide groove 211, and a limiting groove 321 is provided on the side of the slider 32; the rack 33 is provided on the bottom surface of the slider 32, and passes through the long hole 212 and engages with the rotating assembly 4. It should be understood that the side of the slide groove 211 abuts against the two opposite sides of the slider 32, that is, the slider 32 is limited to slide only in the direction of the opening of the slide groove 211. Specifically, the top surface of the slider 32 is coplanar with the top surface of the bottom plate body 21, and the mounting plate 31 is placed on the top surface of the bottom plate body 21.

[0033] In other embodiments, the rotating assembly 4 includes a rotating shaft 41, a gear 42 and a ratchet 43; the rotating shaft 41 is rotatably connected to the connecting plate 22, the gear 42 is coaxially fixed on the rotating shaft 41 and meshes with the rack 33; the ratchet 43 is coaxially fixed at both ends of the rotating shaft 41, and the limiting assembly 5 and the ratchet 43 correspond to each other. The limiting assembly 5 on one side can limit the corresponding ratchet 43 to rotate clockwise, and the limiting assembly 5 on the other side can limit the corresponding ratchet 43 to rotate counterclockwise. Specifically, the rotation directions of the two ratchet 43 are opposite.

[0034] In other embodiments, the limiting assembly 5 includes a limiting coupling 51, a pawl 52 and a torsion spring 53; the limiting coupling is vertically arranged on the connecting plate 22, the pawl 52 is rotatably connected to the limiting coupling 51 and can limit the rotation of the ratchet 43, and one end of the torsion spring 53 is connected to the pawl 52, and the other end is connected to the connecting plate 22. It should be understood that since the two pawls 52 respectively limit the clockwise and counterclockwise rotation of the ratchet 43, that is, respectively control the rack 33 to slide forward or backward, when the position of the fan needs to be changed forward or backward, it is only necessary to rotate the corresponding pawl 52 to keep it away from the corresponding ratchet 43.

[0035] In other solutions, the connection plate 22 is further slidably connected with a limiting plate 6, which can abut against the pawl 52 after sliding, and limit the pawl 52 from rotating toward the ratchet 43. Specifically, the limiting plate 6 and the pawl 52 correspond to each other one by one, and before the pawl 52 needs to be rotated, the limiting plate 6 is lifted so that the pawl 52 is located at the bottom of the limiting plate 6, and then the limiting plate 6 is lowered to abut against the pawl 52, and the pawl 52 is limited from rotating in the opposite direction under the action of the torsion spring 53.

[0036] The fan installation device described above can facilitate adjustment of the position of the fan.
