[0002] A floor fan is a common type of household or commercial electric fan, which generally includes a base, a support rod, and a fan head, and is placed directly on the ground via the base.

[0003] The fan head in a floor fan is quite heavy. To ensure the fan head remains stable during operation, the base is also designed to be heavy. However, this makes the floor fan overall heavy, making it inconvenient for users to move the floor fan. Therefore, there is still room for improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a floor fan that is easy to move.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a floor fan, including a base, a support rod and a fan head connected in sequence. The lower end of the base is recessed upward to form a cavity. The upper end of the base is provided with a plurality of through holes evenly distributed along the circumferential direction. The through holes communicate with the cavity. A plurality of moving units corresponding one-to-one with the through holes are provided in the cavity. The moving unit includes an internal threaded sleeve, a threaded post and a universal wheel. The upper end of the internal threaded sleeve is fixedly connected to the inner bottom surface of the cavity. The internal threaded sleeve and the corresponding through hole are located on the same axis. The threaded post is threadedly connected to the internal threaded sleeve. The upper end of the threaded post is fixedly provided with a handle passing through the through hole. The lower end of the threaded post is connected to the universal wheel.

[0006] Preferably, the handle includes a connecting rod, a rotating seat, and a gripping member. The lower end of the connecting rod passes through the through hole and is fixedly connected to the upper end of the threaded post. The rotating seat is fixedly disposed at the upper end of the connecting rod, and the gripping member is rotatably engaged with the rotating seat.

[0007] Preferably, the grip includes a grip bar, and a buckle is fixedly provided on the upper surface of the base, with the grip bar engaging with the buckle.

[0008] Preferably, the grip further includes a rotating rod and an arc-shaped rod. One end of the rotating rod is axially connected to the rotating seat, and the other end of the rotating rod is fixedly connected to the center of the convex arc surface of the arc-shaped rod. The two ends of the grip correspond one-to-one with the two ends of the arc-shaped rod and are connected.

[0009] Preferably, the buckle includes two side plates, the lower end of which is fixedly connected to the upper end face of the base, and a snap-fit ​​space for snapping the grip bar is formed between the two side plates. A limit block and a pull ring are provided on one side plate, the limit block being located on the side of the side plate facing the snap-fit ​​space, and the pull ring being located on the side of the side plate away from the snap-fit ​​space.

[0010] Preferably, the outer surface of the internal threaded sleeve is provided with a plurality of reinforcing ribs, which are fixedly connected to the inner bottom surface of the cavity.

[0011] Preferably, the lower end of the base is provided with a plurality of reinforcing plates evenly distributed along the circumference, one end of all the reinforcing plates is connected together, the other end of the reinforcing plates is fixedly connected to the edge of the lower end surface of the base, and the reinforcing plates are offset from the moving unit.

[0012] Preferably, the lower end surface of the reinforcing plate is provided with an anti-slip pad.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. By setting a recess in the base and a moving unit in the recess, when the floor fan needs to be moved, the handle can be turned forward. The handle drives the threaded column to rotate and move downward, so that the lowest point of the universal wheel is lower than the lower end of the base. At this time, the floor fan is in contact with the ground through the universal wheel, and the user can easily move the floor fan. After moving to the designated position, the handle can be turned in reverse. The handle drives the threaded column to rotate and move upward, and the universal wheel enters the recess, so that the lowest point of the universal wheel is higher than the lower end of the base. At this time, the floor fan is in contact with the ground through the base. It can be seen that this structural design makes it easy for users to move the floor fan.

[0015] 2. The movable unit acts as a counterweight, increasing the weight of the base and helping to ensure the fan head remains stable during operation;

[0016] 3. The handle has a through hole extending to the top of the base, making it easy for users to rotate the threaded column and making operation relatively simple. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Example 1: As Figures 1 to 4 As shown, a floor fan includes a base 1, a support rod 2, and a fan head 3 connected in sequence. The lower end of the base 1 is recessed upward to form a cavity 11. The upper end of the base 1 is provided with a plurality of through holes 12 evenly distributed along the circumference. The through holes 12 communicate with the cavity 11. A plurality of moving units 4 corresponding to the through holes 12 are provided in the cavity 11. The moving unit 4 includes an internal threaded sleeve 41, a threaded post 42, and a universal wheel 43. The upper end of the internal threaded sleeve 41 is fixedly connected to the inner bottom surface of the cavity 11. The internal threaded sleeve 41 and the corresponding through hole 12 are located on the same axis. The threaded post 42 is threadedly connected to the internal threaded sleeve 41. The upper end of the threaded post 42 is fixedly provided with a handle 44 passing through the through hole 12. The lower end of the threaded post 42 is connected to the universal wheel 43.

[0027] In this embodiment, the perforations 12 are preferably 3, 4 or 5.

[0028] When the floor fan needs to be moved, turn the handle 44 forward. The handle 44 drives the threaded column 42 to rotate and move downward, so that the lowest point of the caster wheel 43 is lower than the lower end surface of the base 1. At this time, the floor fan is in contact with the ground through the caster wheel 43, and the user can easily move the floor fan. After moving to the designated position, turn the handle 44 in reverse. The handle 44 drives the threaded column 42 to rotate and move upward, so that the caster wheel 43 enters the cavity 11, so that the lowest point of the caster wheel 43 is higher than the lower end surface of the base 1. At this time, the floor fan is in contact with the ground through the base 1.

[0029] Example 2: Figures 3 to 5 As shown, the rest of the parts are the same as in Embodiment 1, except that the handle 44 includes a connecting rod 441, a rotating seat 442 and a gripping member 443. The lower end of the connecting rod 441 is provided with a through hole 12 and is fixedly connected to the upper end of the threaded post 42. The rotating seat 442 is fixedly disposed at the upper end of the connecting rod 441, and the gripping member 443 is rotatably engaged with the rotating seat 442.

[0030] In this embodiment, the grip 443 includes a grip bar 4431. A buckle 13 is fixedly provided on the upper surface of the base 1. The grip bar 4431 is engaged with the buckle 13. When not in use, the grip bar 4431 can be engaged with the buckle 13 to prevent the grip bar 4431 from being accidentally touched and causing the threaded column 42 to rotate, thus ensuring stability and reliability.

[0031] Example 3: Figures 3 to 6 As shown, the rest of the components are the same as in Embodiment 2, except that the grip 443 also includes a rotating rod 4432 and an arc-shaped rod 4433. One end of the rotating rod 4432 is axially connected to the rotating seat 442, and the other end of the rotating rod 4432 is fixedly connected to the center of the convex arc surface of the arc-shaped rod 4433. The two ends of the grip 4431 correspond one-to-one with the two ends of the arc-shaped rod 4433 and are connected accordingly. Compared to a single grip 4431, the addition of the rotating rod 4432 and the arc-shaped rod 4433 makes it more convenient to use and provides a better user experience.

[0032] In this embodiment, the buckle 13 includes two side plates 131. The lower end of the side plates 131 is fixedly connected to the upper end face of the base 1. A locking space for locking the grip bar 4431 is formed between the two side plates 131. A limiting block 1311 and a pull ring 1312 are provided on one side plate 131. The limiting block 1311 is located on the side of the side plate 131 facing the locking space, and the pull ring 1312 is located on the side of the side plate 131 away from the locking space. The limiting block 1311 can prevent the locked grip bar 4431 from loosening, providing good stability. The pull ring 1312 allows the user to pull the side plate 131 outward to bend it, thereby removing the grip bar 4431 for use. The side plate 131 is made of elastic material and can recover its shape after bending.

[0033] In this embodiment, the upper end of the limiting block 1311 is provided with an inclined guide surface to facilitate the quick insertion of the grip 4431.

[0034] Example 4: Figure 2 and Figure 4 As shown, the rest of the parts are the same as in Embodiment 1. The difference is that multiple reinforcing ribs 45 are provided on the outer side of the internal threaded sleeve 41. The reinforcing ribs 45 are fixedly connected to the inner bottom surface of the cavity 11. The setting of the reinforcing ribs 45 helps to improve the stability of the structure.

[0035] In this embodiment, the lower end of the base 1 is provided with a plurality of reinforcing plates 14 evenly distributed along the circumferential direction. One end of all the reinforcing plates 14 is connected together, and the other end of the reinforcing plates 14 is fixedly connected to the edge of the lower end face of the base 1. The reinforcing plates 14 are offset from the moving unit 4. The arrangement of the reinforcing plates 14 helps to improve the stability of the structure.

[0036] In this embodiment, an anti-slip pad 15 is provided on the lower end surface of the reinforcing plate 14. The anti-slip pad 15 helps to increase the friction between the base 1 and the ground and improve stability.

[0037] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
