Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1 - 5 shown, a base for a floor fan includes a base 1. The bottom end of the base 1 is fixedly connected with a first anti-slip pad 11. The middle part of the top end of the base 1 is fixedly connected with a fixed frame 12. The top of the fixed frame 12 is rotatably connected with an adjustment mechanism 2. The inner wall of the base 1 is slidably connected with a balance mechanism 3. The adjustment mechanism 2 includes a rotating rod 21. The outer wall of the rotating rod 21 is rotatably connected with the top of the fixed frame 12. The balance mechanism 3 includes a mounting plate 31. The outer wall of the mounting plate 31 is slidably connected with the inner wall of the base 1.

[0025] Through the adjustment mechanism 2, the base 1 can be adapted to different types of terrains. Then, through the balance mechanism 3, the floor fan can be kept balanced to avoid the fan from tipping over.

[0026] As Figures 2 - 4 shown, the left end of the rotating rod 21 is fixedly connected with a driving bevel gear 22. The bottom of the driving bevel gear 22 is engaged with a driven bevel gear 23. The axis of the driven bevel gear 23 is fixedly connected with a rotating shaft 24. The bottom of the rotating shaft 24 is rotatably connected with the inner walls of the fixed frame 12 and the base 1. The bottom of the rotating shaft 24 is fixedly connected with a turntable 25. An arc groove 26 is formed on the outer wall of the turntable 25. The inner wall of the arc groove 26 is slidably connected with a connecting rod 28. The outer wall of the connecting rod 28 is slidably connected with the inner wall of the base 1. One end of the connecting rod 28 is fixedly connected with the outer wall of the mounting plate 31.

[0027] By rotating the rotating rod 21, the rotating rod 21 drives the driving bevel gear 22 to rotate, causing the driving bevel gear 22 to mesh with the driven bevel gear 23. The driven bevel gear 23 drives the rotating shaft 24 to rotate synchronously, causing the rotating shaft 24 to drive the turntable 25 to rotate. When the turntable 25 rotates, the connecting rod 28 slides on the inner wall of the arc-shaped groove 26, thereby driving the connecting rod 28 to slide on the inner wall of the base 1. The connecting rod 28 drives the mounting plate 31 to slide synchronously on the inner wall of the base 1. When the distance that the mounting plate 31 extends is appropriate, the rotation of the rotating rod 21 can be stopped. Subsequently, the floor fan can be placed, making the floor fan more stable, achieving the effect of adjusting the size of the base 1.

[0028] As Figure 2 , Figure 4 shown, a limiting ring 27 is fixedly connected to the outer wall of the turntable 25, and the outer wall of the limiting ring 27 is slidably connected to the inner wall of the base 1.

[0029] When the turntable 25 rotates, it drives the limiting ring 27 to slide on the inner wall of the base 1. The limiting ring 27 limits and guides the turntable 25, making the rotation of the turntable 25 more stable.

[0030] As Figure 2 , Figure 5 shown, a guiding block 32 is fixedly connected to the outer wall of the mounting plate 31, and the outer wall of the guiding block 32 is slidably connected to the inner wall of the base 1. The shape of the guiding block 32 is T-shaped.

[0031] When the mounting plate 31 slides on the inner wall of the base 1, the mounting plate 31 drives the guiding block 32 to slide on the inner wall of the base 1. The guiding block 32 limits and guides the mounting plate 31, preventing the mounting plate 31 from shifting when sliding on the inner wall of the base 1 and increasing the stability of the mounting plate 31.

[0032] As Figure 2 , Figure 5 shown, a support frame 33 is fixedly connected to the top of the mounting plate 31. A threaded rod 34 is threadedly connected to the inner wall of the support frame 33. The bottom of the threaded rod 34 is threadedly connected to the inner wall of the mounting plate 31. The bottom end of the threaded rod 34 is rotatably connected to a cushion block 35. An anti-slip pad two 37 is fixedly connected to the bottom end of the cushion block 35. A guiding rod 36 is fixedly connected to the top end of the cushion block 35. The outer wall of the guiding rod 36 is slidably connected to the inner walls of the mounting plate 31 and the support frame 33.

[0033] By rotating the threaded rod 34, the threaded rod 34 moves downward on the inner walls of the support frame 33 and the mounting plate 31. The threaded rod 34 drives the cushion block 35 to move downward synchronously. The cushion block 35 drives the guide rod 36 to slide synchronously on the inner walls of the mounting plate 31 and the support frame 33. The guide rod 36 guides the cushion block 35, enabling the cushion block 35 to only translate in the vertical direction and unable to rotate. At the same time, the cushion block 35 drives the anti-slip pad two 37 to move synchronously, making the bottom end of the anti-slip pad two 37 contact the ground, thereby supporting the tilting direction of the floor fan, preventing the floor fan from tilting, and achieving the effect of adjusting the balance of the device.

[0034] The working principle of the present utility model: During use, move the device to a suitable position. Subsequently, according to the requirements of the site, rotate the rotating rod 21. The rotating rod 21 drives the driving bevel gear 22 to rotate, causing the driving bevel gear 22 to mesh with the driven bevel gear 23. The driven bevel gear 23 drives the rotating shaft 24 to rotate synchronously, enabling the rotating shaft 24 to drive the turntable 25 to rotate. The turntable 25 drives the limiting ring 27 to slide on the inner wall of the base 1. The limiting ring 27 limits and guides the turntable 25, making the turntable 25 rotate more smoothly. When the turntable 25 rotates, the connecting rod 28 slides on the inner wall of the arc-shaped groove 26, thereby driving the connecting rod 28 to slide on the inner wall of the base 1. The connecting rod 28 drives the mounting plate 31 to slide synchronously on the inner wall of the base 1. The mounting plate 31 drives the guide block 32 to slide on the inner wall of the base 1. The guide block 32 limits and guides the mounting plate 31, ensuring that the mounting plate 31 does not deviate when sliding on the inner wall of the base 1, increasing the stability of the mounting plate 31. When the distance that the mounting plate 31 extends is appropriate, stop rotating the rotating rod 21. Subsequently, place the floor fan, making the floor fan more stable, achieving the effect of adjusting the size of the base 1. When the placement position is uneven and the floor fan tilts, rotate the threaded rod 34, causing the threaded rod 34 to move downward on the inner walls of the support frame 33 and the mounting plate 31. The threaded rod 34 drives the cushion block 35 to move downward synchronously. The cushion block 35 drives the guide rod 36 to slide synchronously on the inner walls of the mounting plate 31 and the support frame 33. The guide rod 36 guides the cushion block 35, enabling the cushion block 35 to only translate in the vertical direction and unable to rotate. At the same time, the cushion block 35 drives the anti-slip pad two 37 to move synchronously, making the bottom end of the anti-slip pad two 37 contact the ground, thereby supporting the tilting direction of the floor fan, preventing the floor fan from tilting, and achieving the effect of adjusting the balance of the device. This greatly improves the user experience.
