[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0025] Example 1: This example provides an adjustable-angle fan blade, such as... Figure 1 As shown, this invention solves the problem that when blades are damaged or need to be replaced, the operator has to open the casing to disassemble the blades, making blade replacement cumbersome. The invention includes a casing 1 and a motor 2 installed inside the casing 1. The rotating shaft of the motor 2 is fixedly connected to a control disk 3. Several adjustable blades 4 are movably inserted into the outer wall of the control disk 3. An adjustment mechanism 5 is installed inside the control disk 3. The adjustment mechanism 5 engages with one end of the adjustable blades 4 inserted into the control disk 3. The adjustment mechanism 5 is used to control the rotation of the adjustable blades 4.

[0026] First, the adjustable blade 4 is inserted into the control panel 3, and the control adjustment mechanism 5 is inserted into the adjustable blade 4 to limit the adjustable blade 4, thereby installing the adjustable blade 4 on the control panel 3. When the angle of the adjustable blade 4 needs to be adjusted, the adjustable blade 4 is rotated by moving the adjustment mechanism 5 to adjust the angle of the adjustable blade 4. Therefore, the adjustable blade 4 is more convenient to adjust.

[0027] When the adjustable blade 4 needs to be replaced, the adjusting mechanism 5 is moved to separate it from the adjustable blade 4. At this time, the adjustable blade 4 loses its limit, which makes it easier for the operator to disassemble and replace the adjustable blade 4.

[0028] Combination Figure 2, in an embodiment of the present utility model, a plurality of connecting rods 21 are provided on the outer wall of the motor 2. One end of the plurality of connecting rods 21 away from the motor 2 is fixedly connected to the inner wall of the casing 1. Through the cooperation of the plurality of connecting rods 21, it is convenient to fixedly install the motor 2 inside the casing 1. Through the motor 2, it is convenient to drive the control disk 3 and the adjustable blades 4 to rotate.

[0029] Combined with Figure 3 , in an embodiment of the present utility model, a movable groove 31 is opened inside the control disk 3. The adjusting mechanism 5 is installed in the movable groove 31. The outer wall of the control disk 3 is provided with mounting grooves 32 corresponding to the number of the adjustable blades 4. The adjustable blades 4 are installed in the mounting grooves 32. Through the movable groove 31, it is convenient to rotate the control disk 3. Through the mounting grooves 32, it is convenient to install the adjustable blades 4.

[0030] Combined with Figure 3 , in an embodiment of the present utility model, the adjustable blade 4 includes a blade main body 41 and a rotating shaft 42. The rotating shaft 42 is rotationally inserted into the mounting groove 32. The blade main body 41 is fixedly arranged at one end of the rotating shaft 42 extending out of the control disk 3. The shape of the rotating shaft 42 is "convex". Through the mounting groove 32, it is convenient to install the rotating shaft 42, and through the rotating shaft 42, it can drive the blade main body 41 to rotate, so as to adjust the angle of the blade main body 41.

[0031] Embodiment 2: Refer to Figure 3 、 Figure 4 , a circular limiting groove 43 is opened on the outer wall of the rotating shaft 42, and a tooth groove 44 is opened in the circular limiting groove 43. When the adjusting mechanism 5 is inserted into the circular limiting groove 43, it is convenient to limit the rotating shaft 42, so as to limit the rotating shaft 42 in the mounting groove 32, thereby prompting the rotating shaft 42 to only be able to rotate and not move up and down.

[0032] The adjusting mechanism 5 includes an electric push rod 51 and a fixed disk 52. The electric push rod 51 is fixedly arranged at the extending end of the fixed disk 52. The outer wall of the fixed disk 52 is fixedly provided with fixing rods 53 corresponding to the number of the adjustable blades 4. One end of the fixing rods 53 away from the fixed disk 52 is fixedly provided with limiting plates 54. The end of the limiting plates 54 is movably inserted into the circular limiting groove 43 for limiting the rotating shaft 42. Through the electric push rod 51, it is convenient to move the fixed disk 52, the fixing rods 53 and the limiting plates 54. When the limiting plates 54 are inserted into the circular limiting groove 43, it is convenient to limit the rotating shaft 42. When the limiting plates 54 are separated from the circular limiting groove 43, the rotating shaft 42 loses its limit, and then it is convenient for the operator to disassemble and replace the rotating shaft 42 and the blade main body 41.

[0033] Embodiment 3: Refer to Figure 3 、 Figure 4One end of the limiting plate 54 is inserted into the annular limiting groove 43 and a toothed plate 55 is fixedly installed thereon. The toothed plate 55 meshes with the toothed groove 44. When the limiting plate 54 moves, it drives the toothed plate 55 to move synchronously. At this time, the toothed plate 55 and the toothed groove 44 cooperate to drive the rotating shaft 42 and the blade body 41 to rotate, thereby facilitating the adjustment of the angle of the blade body 41.

[0034] The height of the inner wall of the annular limiting groove 43 is the same as the height of the end of the limiting plate 54 inserted into the annular limiting groove 43. By setting the height of the inner wall of the annular limiting groove 43 and the height of the end of the limiting plate 54 inserted into the annular limiting groove 43 to be the same, it is easier to reduce the possibility of the limiting plate 54 limiting the up and down sway of the rotating shaft 42, so as to increase the stability of the rotating shaft 42 installed in the mounting groove 32.

[0035] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
