Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a floor fan with good stability. Background Technology

[0002] A floor fan is a common household appliance. It uses a motor to drive the fan blades to rotate and create airflow in the room. The airflow blows onto the user to achieve a cooling effect. Currently, most floor fans on the market use a disc-shaped support base with a counterweight. This type of support base has good stability; however, the overall size of the disc-shaped support base is relatively large, making it inconvenient to transport and store. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a floor fan with good stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A stable floor fan includes a fan head, a switch control box, a vertical pole, and a support base. The support base includes a support seat located at the lower end of the vertical pole. Three support rods that can swing up and down are evenly hinged along the circumference of the support seat. A sliding sleeve that can move up and down is fitted on the vertical pole. A reinforcing rod corresponding to the support rods is hinged to the sliding sleeve. The fan also includes a first fixing member and a second fixing member. The first fixing member can fix the sliding sleeve to the vertical pole, and the second fixing member is used to fix the reinforcing rods to the support rods.

[0006] In some embodiments, a stud is provided on one side of the sliding sleeve, and the first fixing member is a first bolt threaded onto the stud, the threaded end of the first bolt abutting against the outer wall of the upright.

[0007] In some embodiments, a groove is provided at the upper end of the support rod, the second fixing member is a second bolt, and the lower end of the reinforcing rod can abut against the groove and be fixed in the groove by the second bolt.

[0008] In some embodiments, when the second fastener securely connects the reinforcing rod to the support rod, the support rod is in a horizontal state extending outwards.

[0009] In some embodiments, a storage groove extending along the length direction is provided at the upper end of the support rod, and when the support rod is flipped upward to a vertical state, the reinforcing rod can be stored in the storage groove.

[0010] In some embodiments, an L-shaped baffle corresponding to the support rod is provided on the sliding sleeve. When the support rod is flipped upwards to a vertical state, the L-shaped baffle can follow the movement of the sliding sleeve and limit and fix the upper end of the support rod.

[0011] In some embodiments, an avoidance notch is provided on the L-shaped baffle, and the reinforcing rod can be flipped within the avoidance notch.

[0012] In some embodiments, the lower end of the support rod is provided with anti-slip ridges.

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

[0014] 1. When in use, the support base can be extended outward through the support rod, then reinforced by the reinforcing rod, then connected and fixed to the support rod by the second fixing member, and finally fixed by the sliding sleeve by the first fixing member. Thus, the reinforcing rod connects and supports the upright and the support rod, greatly improving the stability and firmness of the support base.

[0015] 2. In addition, when the support base is shipped or not in use, the support rods and reinforcing rods can be swung and stored on one side of the uprights, which greatly reduces the overall volume of the support base, saves space, and facilitates storage and transportation.

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0021] like Figures 1-4The floor fan shown includes a fan head 1, a switch control box 2, a pole 3, and a support base 4. The support base 4 includes a support seat 5 located at the lower end of the pole 3. Three support rods 6 that can swing up and down are evenly hinged along the circumference of the support seat 5. A sliding sleeve 7 that can move up and down is fitted on the pole 3. A reinforcing rod 8 corresponding to the support rod 6 is hinged to the sliding sleeve 7. The fan also includes a first fixing member and a second fixing member. The first fixing member can fix the sliding sleeve 7 to the pole 3, and the second fixing member is used to fix the reinforcing rod 8 to the support rod 6.

[0022] According to the above structure, when the support base 4 is in use, it can be extended outward by the support rod 6, and then the support rod 6 can be reinforced by the reinforcing rod 8. Then, the reinforcing rod 8 and the support rod 6 can be connected and fixed by the second fixing member. Finally, the sliding sleeve 7 can be fixed by the first fixing member. Thus, the upright 3 and the support rod 6 can be connected and supported by the reinforcing rod 8, which greatly improves the stability and firmness of the support base 4.

[0023] In addition, when the support base frame 4 is shipped or not in use, the support rod 6 and the reinforcing rod 8 can be swung and fitted together on one side of the upright 3, which greatly reduces the overall volume of the support base frame 4, saves space, and facilitates storage and transportation.

[0024] See Figure 2 , Figure 4 As shown, a stud 21 is provided on one side of the sliding sleeve 7. The first fixing member is a first bolt 22 threadedly connected to the stud 21. The threaded end of the first bolt 22 can abut against the outer wall of the upright 3. When locking the sliding sleeve 7, the first bolt 22 can be tightened directly against the upright 3. The structure is simple and the operation is convenient.

[0025] See Figure 2 , Figure 3 As shown, a groove 31 is provided at the upper end of the support rod 6, the second fixing member is the second bolt 32, and the lower end of the reinforcing rod 8 can abut against the groove 31 and be fixed in the groove 31 by the second bolt 32.

[0026] Furthermore, when the second fixing member fixes the reinforcing rod 8 to the support rod 6, the support rod 6 is in a horizontal state extending outward. When the support base 4 is in use, the support rod 6 is first unfolded horizontally outward, and then the lower end of the reinforcing rod 8 is supported and abutted against the groove 31. Then, the second bolt 32 passes through the reinforcing rod 8 and is threadedly connected to the screw hole in the groove 31.

[0027] See Figures 2-4As shown, a storage groove 51 extending along the length direction is provided at the upper end of the support rod 6. When the support rod 6 is flipped upward to a vertical state, the reinforcing rod 8 can be stored in the storage groove 51, thereby further reducing the overall volume when stored.

[0028] See Figure 4 As shown, an L-shaped baffle 61 corresponding to the support rod 6 is provided on the sliding sleeve 7. When the support rod 6 is flipped upward to a vertical state, the L-shaped baffle 61 can follow the movement of the sliding sleeve 7 to limit and fix the upper end of the support rod 6, so that the support rod 6 will not swing at will, thereby ensuring stability when stored.

[0029] See Figure 2 As shown, an avoidance notch 71 is provided on the L-shaped baffle 61, and the reinforcing rod 8 can be flipped within the avoidance notch 71, so as not to affect the normal use of the reinforcing rod 8.

[0030] In this invention, anti-slip ridges 81 are provided at the lower end of the support rod 6, which can further improve the stability of the support base 4 during operation.

[0031] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
