A drive gear is installed in the middle of the outer wall of the rotating shaft, and a driven gear is rotatably connected in the middle of the outer wall of the slot fixing rod. The drive gear and the driven gear are meshed.

[0007] As a preferred embodiment of this utility model, a first rotating wheel is installed on both sides of the outer wall of the rotating shaft, and a second rotating wheel is rotatably connected to both sides of the outer wall of the fixed rod.

[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-4In this embodiment: an energy-saving fan rotor frequency converter includes a placement seat 1 and a base 11. The upper surface of the placement seat 1 is provided with a sliding groove 2 at equal angles in the circumference. A motor 3 is installed on the lower inner surface of the placement seat 1. A turntable 4 is rotatably connected inside the placement seat 1. The output end of the motor 3 is installed in the middle of the lower surface of the turntable 4. A through groove 5 is provided on the surface of the turntable 4 at equal angles in the circumference. I-shaped rods 6 are slidably connected to the inner wall of the through groove 5. The upper part of the outer wall of the I-shaped rod 6 is slidably connected to the inner wall of the sliding groove 2. An L-shaped plate 7 is fixedly connected to the top of the I-shaped rod 6. A clamping block 8 is fixedly connected to the upper part of the L-shaped plate 7. A rubber pad 9 is fixedly connected to the inner side of the clamping block 8. A fan assembly 10 is placed on the upper surface of the placement seat 1. The inner side of the clamping block 8 is in contact with the outer wall of the fan assembly 10.

[0023] In this embodiment, the fan assembly 10 is placed on the upper surface of the placement base 1, and then the turntable 4 is rotated by starting the motor 3, which causes the I-shaped rod 6 to slide in the through groove 5. With the cooperation of the sliding groove 2, the I-shaped rod 6 can make linear movement in the sliding groove 2, thereby causing the I-shaped rod 6 to move the L-shaped plate 7 towards the fan assembly 10, so that the clamping block 8 clamps and fixes the fan assembly 10. The through groove 5 is arc-shaped, which enables the installation of fan assemblies 10 of different sizes and specifications on the placement base 1, thus improving applicability.

[0024] Furthermore, a fixing frame 12 is fixedly connected to both sides of the upper surface of the base 11, and a sliding plate 13 is fixedly connected to both sides of the lower surface of the placement seat 1. The outer wall of the sliding plate 13 is slidably connected to the inner wall of the fixing frame 12. A motor 14 is installed on the upper part of the outer wall of one of the fixing frames 12. A rotating shaft 15 is installed at the output end of the motor 14. One end of the rotating shaft 15 is rotatably connected to the upper side of the other fixing frame 12. A fixing rod 16 is fixedly connected to the lower part of the adjacent surfaces of the two sliding plates 13. A drive gear 17 is installed in the middle of the outer wall of the rotating shaft 15. A driven gear 18 is rotatably connected in the middle of the outer wall of the slot fixing rod 16. The drive gear 17 and the driven gear 18 are meshed.

[0025] In this system, the motor 14 drives the rotating shaft 15 to rotate, which in turn drives the driving gear 17 to rotate. The driving gear 17 drives the driven gear 18 to rotate on the fixed rod 16. Since the driving gear 17 and the driven gear 18 are respectively mounted on the rotating shaft 15 and the fixed rod 16 on one side of their surfaces, when the driving gear 17 drives the driven gear 18 to rotate, the fixed rod 16 can drive the sliding plate 13 to slide within the fixed frame 12 to adjust the height of the placement seat 1. This allows the height of the placement seat 1 to be adjusted according to the needs of the workers.

[0026] Furthermore, rotating wheels 19 are installed on both sides of the outer wall of the rotating shaft 15, and rotating wheels 20 are rotatably connected to both sides of the outer wall of the fixing rod 16. One side of rotating wheel 19 and one side of rotating wheel 20 are staggered.

[0027] The stability of the fixing rod 16 can be improved by setting up the first rotating wheel 19 and the second rotating wheel 20.

[0028] Furthermore, a through hole 22 is provided on the upper part of one side of one of the fixing brackets 12, and a positioning hole 23 is provided on one side of one of the sliding plates 13. An insert rod 24 is inserted into the inner wall of the through hole 22 and the positioning hole 23.

[0029] When the height of the placement seat 1 is adjusted, since several sets of positioning holes 23 are equally spaced on one side of the slide plate 13, the slide plate 13 can be positioned by inserting the rod 24 into the through hole 22 and the positioning hole 23 to prevent it from sliding.

[0030] Furthermore, buffer telescopic rods 21 are installed at the four corners of the upper surface of the base 11, and the top ends of the buffer telescopic rods 21 are respectively installed at the four corners of the lower surface of the placement seat 1.

[0031] The stability of the placement seat 1 can be improved by setting the buffer telescopic rod 21.

[0032] Furthermore, brake wheels 25 are installed at the four corners of the lower surface of the base 11;

[0033] The device can be moved to the desired location by means of the brake wheel 25.

[0034] Preferably, the fan assembly 10 includes a fan 1003 and a mounting base 1001. The mounting base 1001 is disposed on the upper surface of the placement base 1. The inner side of the clamping block 8 is in contact with the outer wall of the mounting base 1001. A variable frequency motor 1002 is mounted on the upper surface of the mounting base 1001. The output end of the fan 1003 is connected to the input end of the variable frequency motor 1002.

[0035] The working principle and usage process of this utility model are as follows: The fan assembly 10 is placed on the upper surface of the placement base 1. Then, the starter motor 3 drives the turntable 4 to rotate, causing the I-shaped rod 6 to slide within the through groove 5. With the cooperation of the sliding groove 2, the I-shaped rod 6 can move linearly within the sliding groove 2, thereby causing the I-shaped rod 6 to move the L-shaped plate 7 towards the fan assembly 10. This allows the clamping block 8 to clamp and fix the fan assembly 10. The through groove 5 is arc-shaped, thus enabling the installation of fan assemblies 10 of different sizes and specifications on the placement base 1, improving applicability. The starter motor 14 drives the rotating shaft 15 to rotate, which in turn drives the drive gear 17. When the drive gear 17 rotates, it drives the driven gear 18 to rotate on the fixed rod 16. Since the drive gear 17 and the driven gear 18 are respectively mounted on the rotating shaft 15 and the fixed rod 16 on one side, when the drive gear 17 drives the driven gear 18 to rotate, the fixed rod 16 can drive the slide plate 13 to slide in the fixed frame 12 to adjust the height of the placement seat 1. This allows the height of the placement seat 1 to be adjusted according to the needs of the worker. After the height of the placement seat 1 is adjusted, since several sets of positioning holes 23 are equally spaced on one side of the slide plate 13, the slide plate 13 can be positioned by inserting the rod 24 into the through hole 22 and the positioning hole 23 to prevent it from sliding.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
