Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, in the present embodiment, a fan blade of a novel industrial fan includes a fan turntable 1, a groove 10 is disposed on an inner side of the fan turntable 1, a movable screw 2 is connected inside the fan turntable 1, one end of the movable screw 2 is connected with the fan blade 3, a connecting rod 4 is disposed on an inner side of the fan blade 3, a movable disc 5 is disposed around an outer surface of the connecting rod 4, a hole 6 is disposed on an inner side of the movable disc 5, a connecting ring 7 is disposed around an outer surface of the hole 6, one end of the connecting ring 7 is connected with a connecting sheet 8, a connecting shaft 9 is disposed through an inner side of the connecting sheet 8, and a bearing 11 is disposed around an outer surface of the movable screw 2; set up movable screw rod 2, make the connected mode of fan and fan carousel 1 by welding machine fixed connection, change into the screw rod and connect, make flabellum 3 easily install and dismantle, simultaneously through bearing 11's design, make flabellum 3 can be for fan carousel 1 free rotation to change fan carousel 1 and flabellum 3's the angle of cutting to one side relatively, thereby reach the change of realizing the air-out direction under the unchangeable circumstances of fan carousel 1 direction of rotation.

In the embodiment, the fan turntable 1 is circular, the groove 10 is circular, and the circle center of the fan turntable 1 is overlapped with the circle of the groove 10, so that the whole equipment is balanced when the fan turntable 1 rotates; the size of the groove 10 is matched with that of the external rotating shaft, and the fan turntable 1 is fixedly connected with the external rotating shaft through a bolt, so that the fan turntable 1 is more stably connected with the rotating shaft; the inner side of the fan turntable 1 is provided with a threaded hole, and the inner diameter size of the threaded hole is matched with the outer diameter size of the movable screw 2, so that the structure for connecting the fan turntable 1 and the fan blades 3 is more stable; the movable screw 2 is movably connected with the fan blades 3 through a bearing 11, the number of the fan blades 3 is multiple, and the multiple groups of the fan blades 3 are movably connected through a connecting ring 7 and a connecting sheet 8, so that the fan blades 3 can flexibly rotate relative to the fan turntable 1; the inner diameter of the hole 6 is matched with the outer diameter of the connecting rod 4, and two groups of connecting rods 4 are arranged in one group of fan blades 3, so that the connecting sheet 8 and the connecting ring 7 are movably connected with the fan blades 3; the connecting ring 7 and the connecting sheet 8 are movably connected with the fan blades 3 through the connecting rod 4 and the movable disc 5, and the movable disc 5 is oval in shape, so that the connecting structure is more reasonable; the number of the connecting sheets 8 is four, every two groups of the connecting sheets 8 are movably connected through a connecting shaft 9, and the connecting sheets 8 are movably connected with the connecting ring 7 through the connecting shaft 9, so that the fan blades 3 can flexibly rotate relative to the fan turntable 1. And does not affect the relative stability between the sets of fan blades 3.

The working principle and the using process of the invention are as follows: when the fan blades 3 are damaged and need to be replaced, a user only needs to rotate the connecting rod 4 by means of a tool such as a wrench and the like to separate the movable disc 5 from the connecting ring 7 and the connecting sheet 8, then rotates the movable screw 2 through the wrench to replace the corresponding damaged single group of fan blades 3, when the user needs to go out of the forward wind of the fan, the user only needs to move the connecting sheet 8 and the connecting ring 7 to convert the connecting sheet 8 and the connecting ring 7 from the figure 1 to the relative positions shown in the figure 2 to deflect and blow out the wind in the forward direction, the relative positions of the connecting ring 7 and the connecting sheet 8 shown in the figure 2 can be fixed by screwing the connecting shaft 9, when the wind in the reverse direction needs to be blown out, the connecting ring 7 and the connecting sheet 8 are only needed to be loosened to move to the relative positions opposite to the figure 2, and at the moment, the tangential angle of the fan blades 3 relative to the fan turntable 1 is opposite to the tangential angle of the wind in the forward direction, at this time, the reverse wind can be blown out without changing the rotation direction of the fan turntable 1.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims.
