[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] See Figures 1-6, a pitching and swinging structure 100 of a fan provided by the present utility model. The pitching and swinging structure 100 of the fan includes a floor-standing pipe 10 and a fan blade 20 rotatably connected to the top of the floor-standing pipe 10. A bracket joint 11 is provided at the top of the floor-standing pipe 10, and a fan joint 21 for mating connection with the bracket joint 11 is provided at the bottom of the fan blade 20. A limiting component 30 for limiting the pitching angle of the fan blade 20 is provided between the fan joint 21 and the bracket joint 11, and the fan blade 20 is rotatably connected to the bracket joint 11 through the limiting component 30. In the embodiment provided by the present utility model, by using the limiting component 30 to rotatably connect the fan joint 21 of the fan blade 20 to the bracket joint 11 of the floor-standing pipe 10, the operation of the fan blade 20 pitching and swinging relative to the floor-standing pipe 10 can be completed, thereby effectively simplifying the pitching and swinging structure of the fan blade 20, simplifying the installation steps, and improving the installation efficiency. The limiting component 30 in the pitching and swinging structure 100 of the fan provided by the present utility model includes a fixed tooth 31 fixed on the bracket joint 11 and a plurality of plastic steel beads 32 elastically connected to the fan joint 21. A plurality of limiting structures are provided on the fixed tooth 31, and the plastic steel beads 32 are embedded in the limiting structures of the fixed tooth 31, so that the fan blade 20 and the bracket joint 11 are clamped and fixed. In the embodiment provided by the present utility model, after the user manually pushes the fan blade 20 to pitch and swing relative to the floor-standing pipe 10 to a suitable position, by embedding the two plastic steel beads 32 elastically connected in the fan joint 21 into the limiting structures of the fixed tooth 31, the operation of limiting the pitching and swinging angle of the fan blade 20 can be realized, thereby effectively meeting the user's demand for blowing air at different angles and improving the user experience during use.

[0029] As Figure 2 and Figure 3 shown, in the embodiment provided by the present utility model, a fixed shaft 311 is provided in the middle of the fixed tooth 31, the limiting structure is a limiting part symmetrically arranged on both sides of the fixed shaft 311, and a plurality of limiting grooves 312 are provided on the limiting part. The plastic steel beads 32 are embedded in the limiting grooves 312, so that the fan blade 20 and the bracket joint 11 are clamped and fixed. During the process that the user manually pushes the fan blade 20 to pitch relative to the floor-standing pipe 10, the two plastic steel beads 32 elastically connected in the fan joint 21 are sequentially embedded in the limiting grooves 312 on the limiting part. After the user adjusts the fan blade 20 to a suitable pitching and swinging angle, the pitching angle can be effectively limited through the plastic steel beads 32 embedded in the limiting grooves 312, avoiding the pitching and swinging of the fan blade 20 relative to the floor-standing pipe 10, thereby effectively meeting the user's demand for blowing air at different angles and improving the user experience during use.

[0030] As Figure 2 and Figure 5As shown in the figure, a fixing groove 111 for fixing the fixing teeth 31 is provided inside the bracket joint 11 of the present utility model. A fixing boss 313 is provided on the back of the fixing teeth 31. The fixing boss 313 of the fixing teeth 31 is embedded in the fixing groove 111 of the bracket joint 11, so that the fixing teeth 31 and the bracket joint 11 are clamped and fixed. By embedding the fixing boss 313 of the fixing teeth 31 into the fixing groove 111 of the bracket joint 11, the fixing teeth 31 and the bracket joint 11 are clamped and fixed, which can ensure the stability of the fixed connection between the fixing teeth 31 and the bracket joint 11 while effectively simplifying the installation structure between the fixing teeth 31 and the bracket joint 11, simplifying the installation operation, improving the installation efficiency, and further improving the overall installation efficiency of the pitching and yawing structure 100 of the fan.

[0031] As Figure 4 shown, in the embodiment provided by the present utility model, two plastic steel beads 32 are elastically connected to the fan joint 21 through two springs 33, and two mounting holes 211 for mounting the springs 33 are provided on the fan joint 21. By directly embedding the springs 33 into the mounting holes 211 of the fan joint 21, the operation of mounting the springs 33 on the fan joint 21 can be effectively simplified, thereby further improving the installation efficiency. The plastic steel beads 32 provided by the present utility model include a connecting section 321 and a clamping section 322. The connecting section 321 is embedded in the spring 33, and the clamping section 322 is used for embedding into the limiting groove 312 of the fixing teeth 31. By embedding the connecting section 321 of the plastic steel beads 32 into the spring 33, the stability of the elastic connection of the plastic steel beads 32 to the fan joint 21 through the spring 33 can be effectively ensured while further simplifying the installation operation of the elastic connection of the plastic steel beads 32 to the fan joint 21, and further improving the installation efficiency.

[0032] Moreover, the diameter of the clamping section 322 of the plastic steel beads 32 gradually decreases towards the fixing teeth 31 and forms a guiding inclined surface. Thus, in the process of the user pushing the fan blade 20 to pitch and yaw relative to the floor tube 10, the guiding inclined surface can effectively make the plastic steel beads 32 move more conveniently in the process of being sequentially embedded into the limiting groove 312 of the fixing teeth 31, thereby effectively improving the smoothness during the process of pushing the fan blade 20 to pitch and yaw relative to the floor tube 10, and further improving the user experience during use.

[0033] As Figure 2 and Figure 3As shown in the figure, two hooks 314 are provided at the front end of the fixed shaft 311 of the fixed gear 31. A first fixing hole 212 for the fixed shaft 311 to pass through is provided on the fan joint 21. The fixed shaft 311 of the fixed gear 31 passes through the first fixing hole 212 and is fixedly engaged with the fan joint 21 through the hooks 314. After passing the fixed shaft 311 of the fixed gear 31 through the first fixing hole 212, by engaging the two hooks 314 at the front end of the fixed shaft 311 with the first fixing hole 212, the operation of installing the fixed gear 31 on the fan joint 21 can be completed, effectively simplifying the installation operation and further improving the installation efficiency. A torsion spring 40 for supporting the fan blade 20 is also provided inside the fan joint 21. One end of the torsion spring 40 abuts against the inside of the fan joint 21, and the other end abuts against the inside of the bracket joint 11. The fan blade 20 can be effectively supported by the torsion spring 40 to prevent the fan blade 20 from automatically falling, and the force required when the plastic steel bead 32 is engaged in the limiting groove 312 of the fixed gear 31 can be effectively reduced, thereby effectively ensuring the stability of the pitching angle of the fan blade 20 relative to the floor-standing pipe 10 defined by the limiting component 30 and improving the service life.

[0034] As Figure 1 shown, the pitching and swinging head structure 100 of the fan further includes a screw rod 50. A second fixing hole 112 for the stud section of the screw rod 50 to pass through is provided on the bracket joint 11. The stud section passes through the second fixing hole 112, the fixed shaft 311 of the fixed gear 31, and the first fixing hole 212 of the fan joint 21 and extends out of the bracket joint 11. The pitching and swinging head structure 100 of the fan further includes a nut 51. The nut 51 is locked on the stud section of the screw rod 50 extending out of the bracket joint 11 to fix the screw rod 50 on the bracket joint 11. After passing the screw rod 50 through the second fixing hole 112, the fixed shaft 311 of the fixed gear 31, and the first fixing hole 212 of the fan joint 21 and extending out of the bracket joint 11, by locking the nut 51 on the stud section of the screw rod 50 extending out of the bracket joint 11, the stability of the screw rod 50 installed on the bracket joint 11 and the stability of the rotational connection between the fan blade 20 and the floor-standing pipe 10 can be effectively ensured. During the process of the user pushing the fan blade 20 to pitch and swing relative to the floor-standing pipe 10, the fan joint 21 rotates around the stud section of the screw rod 50, thereby effectively ensuring the concentricity between the fan joint 21 and the fixed gear 31 and ensuring that the plastic steel bead 32 is accurately embedded in the limiting groove 312 of the fixed gear 31.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
