[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1 to 6This utility model provides a technical solution: an easily adjustable fan, comprising: a support base 1; a support column 2 installed on the top of the support base 1, with an inner sliding support column 3 slidably disposed on the inner side of the support column 2; a support body 4 fixedly connected to the top of the inner sliding support column 3, with a support top seat 5 bolted to the top of the support body 4; a rotating support rod 7 rotatably disposed inside the support top seat 5, with an inner rotating support block 6 fixedly connected to the outer side of the rotating support rod 7, and the inner rotating support block 6 rotatably connected to the support top seat 5; a rotating part disposed on one side of a side fixing box 8, with the rotating support rod 7 connected to the rotating part; a fan head 9 installed on the top of the inner rotating support block 6, with fan blades 10 mounted on the output shaft of the fan head 9; side slots 18 equidistantly opened on one side of the inner sliding support column 3; a side support box 11 bolted to one side of the support column 2, with an inclined locking block 12 slidably disposed inside the side support box 11 that cooperates with the side slot 18, and the inclined locking block 12 slidably connected to the support column 2.
[0028] It should be noted that in this embodiment, the bottom fixing block 17 of the support column 2 cooperates with the mounting groove on the top of the support base 1, the fixing screw 21 on one side of the side mounting plate 20 enters the mounting through hole 19, the limiting nut 22 is threaded on the outside of the fixing screw 21, the bottom fixing block 17 of the support column 2 is fixedly installed in the mounting groove opened on the top of the support base 1, and the bottom fixing block 17 of the support body 4 is installed in the mounting groove opened on the top of the inner sliding column 3. When it is necessary to adjust the height position of the inner sliding column 3 in the support column 2, it is done by adjusting the bottom fixing block 17 of the support body 4 in the mounting groove opened on the top of the inner sliding column 3. Rotate the limiting bolt 15 outwards and pull the pull rod 13 outwards. The pull rod 13 drives the inclined plate block 12 to move into the side support box 11. The inclined plate block 12 presses against the spring 14 on the outside of the pull rod 13. The inclined plate block 12 leaves the currently limited side latch 18, allowing the position of the inner sliding support column 3 within the support column 2 to be adjusted. Release the pull rod 13, and the spring 14 returns to its original position, driving the inclined plate block 12 into the side latch 18 at a new height position on one side. This limits and fixes the inner sliding support column 3 inside the support column 2. Rotate the limiting bolt 15 inwards, and the limiting bolt 15 presses against the inclined plate block. The movement of 12 is restricted, which improves the stability after the position of the inner sliding support 3 is adjusted and fixed. The core components inside the fan head 9 include: motor: driving the fan blades 10 to rotate; control circuit: speed regulation and timing; motor bracket: fixing and shock absorption; outer shell: protection and airflow guidance; support base. When the support column 2 and the inner sliding support 3 are not needed, the fixing screw 21 installed between the support base 1 and one of the bottom fixing blocks 17, and between the inner sliding support 3 and the other bottom fixing block 17 can be removed. The limiting nut 22 on the outside of the fixing screw 21 can be rotated and removed, and the side mounting plate 20 can be installed. Remove the fixing screw 21, disassemble the support column 2 and the inner sliding column 3, and then install the bottom fixing block 17 at the bottom of the support body 4 in the mounting groove at the top of the support base 1. Remove the support column 2 and the inner sliding column 3 as a whole. Drive the worm gear 25 to rotate through the output end of the servo motor 26. When the worm gear 25 rotates, it drives the meshing worm wheel 24 to rotate. The worm wheel 24 drives the inner rotating support rod 7 to rotate. The rotating support rod 7 drives the outer inner rotating support block 6 to rotate in the support top seat 5. Adjust the overall angle of the machine head 9, fan blade 10 and screen cover up and down.
[0029] In this application, the servo motor, motor, control circuit, and timer are all coordinated and controlled by the controller. The specific architecture and operation logic are consistent with the existing technology in this field. The servo motors used are all equipped with encoders, which can provide real-time feedback on information such as the speed of the servo motor. This control method has been successfully applied in many similar industrial scenarios, so it will not be discussed in detail here.
[0030] In one embodiment, such as Figures 1 to 6As shown, the bottom of both the support column 2 and the support body 4 is fixedly connected to a bottom fixing block 17. The top of both the support base 1 and the inner sliding column 3 is provided with an installation groove that mates with the bottom fixing block 17. The support base 1, the inner sliding column 3 and the bottom fixing block 17 are each provided with two symmetrical installation through holes 19. A fixing screw 21 is installed inside the installation through hole 19. A side mounting plate 20 is welded to one end of the fixing screw 21. A limit nut 22 is threaded on the outside of the fixing screw 21. The outer side of both the inner sliding column 3 and the support base 1 is provided with a side slot 23 that mates with the side mounting plate 20.
[0031] It should be noted that in this embodiment, the side mounting plate 20 is limited inside the side slot 23, and the limiting nut 22 is threaded on the outside of the fixing screw 21. The fixing screw 21 passes through the mounting through hole 19 opened inside the bottom fixing block 17, the support base 1, and the inner sliding column 3 to splice and install the support column 2, the inner sliding column 3, the support base 1, and the support body 4.
[0032] In one embodiment, such as Figures 1 to 6 As shown, the rotating part includes a side fixing box 8, a worm gear 24, a worm 25, and a servo motor 26. The side fixing box 8 is bolted to one side of the support top seat 5. The rotating support rod 7 is rotatably connected to the side fixing box 8. The worm gear 24 is fixedly connected to the outside of the rotating support rod 7. The worm 25 is rotatably arranged inside the side fixing box 8. The worm 25 is meshed with the worm gear 24. The servo motor 26 is bolted to one side of the side fixing box 8. The output end of the servo motor 26 is fixedly connected to the worm 25.
[0033] It should be noted that in this embodiment, the worm 25 is driven to rotate by the output end of the servo motor 26. When the worm 25 rotates, it drives the meshing worm wheel 24 to rotate. The worm wheel 24 drives the inner rotating support rod 7 to rotate and adjust. The inner rotating support block 6 is rotated and adjusted inside the support top seat 5, thereby adjusting the up and down orientation angle of the machine head 9 and the fan blade 10.
[0034] In one embodiment, such as Figures 1 to 6 As shown, a pull rod 13 is fixedly connected to one side of the inclined block 12. The pull rod 13 is slidably connected to the side support box 11. A spring 14 is sleeved on the outside of the pull rod 13. A limiting bolt 15 that mates with the inclined block 12 is installed in the internal thread of the side support box 11.
[0035] It should be noted that in this embodiment, the movement position of the inclined block 12 in the side support box 11 is restricted by the limiting bolt 15 to avoid the situation where the inclined block 12 is separated from the side latch 18, which would affect the limiting and fixing stability of the inner sliding column 3 inside the support column 2.
[0036] In one embodiment, such as Figures 1 to 6 As shown, an inner sliding support column 16 is slidably installed inside the inner sliding support column 3. The bottom end of the inner support guide column 16 is fixedly connected to the support column 2. A mesh cover that cooperates with the fan blade 10 is provided on one side of the machine head 9.
[0037] It should be noted that in this embodiment, the inner sliding support column 3 is limited to sliding on the outside of the inner support guide column 16, thereby improving the adjustment stability of the inner sliding support column 3 within the support column 2.
[0038] In one embodiment, such as Figures 1 to 6 As shown, a controller is installed on one side of the support body 4.
[0039] It should be noted that in this embodiment, the fan is centrally controlled by a controller.
