[0002] Axial flow fans are a type of fan in which the airflow direction is the same as the axis of the fan blades. They have a wide range of applications. They are called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are usually used in applications where the flow rate requirement is high and the pressure requirement is low.

[0003] When using an axial flow fan, the motor inside the fan needs to be connected to the power supply and started to drive the fan blades to rotate. However, existing axial flow fans can only move air according to the direction of the mounting plate. After installation, the direction of air movement of the axial flow fan cannot be adjusted according to the needs, which can easily limit the scope of use and affect the performance. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] An adjustable axial flow fan includes:

[0026] The main body includes a housing 1. A mounting bracket 11 is fixedly connected to the inner side of the housing 1, and a mounting plate 14 is installed on the outer side of the housing 1. A motor 12 is fixedly connected to the surface of the mounting bracket 11, and a fan blade 13 is installed on the surface of the motor 12. In the process of using the axial flow fan, the connected lines are first connected to the power supply and the motor 12 is started to drive the fan blade 13 to rotate inside the housing 1, thereby enabling the axial flow fan to move air. Two sets of mounting plates 14 are provided, and the axial flow fan can be installed by installing them.

[0027] The adjustment mechanism includes a connecting plate 2, which is fixedly connected to the surface of the mounting plate 14. The surface of the connecting plate 2 is fixedly connected to a mounting chamber 21. The surface of the mounting chamber 21 is provided with a connecting hole 22 and a movable groove 23. The surface of the outer shell 1 is fixedly connected to a connecting column 24. The surface of the connecting column 24 is fixedly connected to a rotating plate 25. The surface of the rotating plate 25 is fixedly connected to a screw 26. The surface of the screw 26 is equipped with a nut 27. Under the connection action of the connecting plate 2, the mounting chamber 21, the connecting column 24 and the rotating plate 25, the outer shell 1 and the two sets of mounting plates 14 can be connected.

[0028] Furthermore, the two sides of the connecting plate 2 are fixedly connected to the surface of the mounting plate 14. The inner diameter of the mounting chamber 21 is the same as the diameter of the rotating plate 25, the diameter of the connecting hole 22 is the same as the diameter of the connecting column 24, and the surface of the movable groove 23 is semi-circular. The two sets of mounting plates 14 after being split can be connected through the connecting plate 2 to realize the installation of the mounting chamber 21. At the same time, with the connection between the mounting chamber 21 and the rotating plate 25, the connecting plate 2 and the connecting column 24 can be limited and connected, so that the installed axial flow fan rotates around the connecting column 24 as the center.

[0029] Furthermore, the connecting post 24 is rotatably connected to the surface of the connecting hole 22, the rotating plate 25 is rotatably connected to the inner surface of the mounting chamber 21, and the screw 26 is movably connected to the surface of the movable groove 23. One end of the connecting post 24 is mounted on the surface of the outer shell 1, and the other end is mounted on the surface of the rotating plate 25. The connecting post 24 and the screw 26 can be connected through the rotating plate 25, and the screw 26 can slide along the surface of the movable groove 23 under the action of rotating the connecting post 24.

[0030] Furthermore, one end of the screw 26 is fixedly connected to the surface of the rotating plate 25, and the other end of the screw 26 is threadedly connected to the inner surface of the nut 27. The nut 27 is abutted against the outer surface of the mounting chamber 21. The length of the nut 27 is less than the length of the screw 26. With the connection of the screw 26 and the nut 27, the rotating connecting column 24 and the rotating plate 25 can be limited and fixed, thereby limiting and fixing the axial flow fan after angle adjustment.

[0031] Furthermore, a rotating mechanism is provided on the surface of the nut 27. The rotating mechanism includes a mounting block 3, which is fixedly connected to the surface of the nut 27. A through hole 31 is provided inside the mounting block 3. A movable rod 32 is movably connected to the surface of the through hole 31. A threaded groove 33 is provided on the surface of the movable rod 32. A limiting block 34 is installed on the surface of the movable rod 32. A threaded block 35 is fixedly connected to the surface of the limiting block 34. When the nut 27 is connected to the screw 26 and abuts against the surface of the mounting chamber 21, the screw 26 abuts against the surface of the mounting block 3. By setting the mounting block 3, the movable rod 32 can be installed, which makes it more convenient to rotate the nut 27 without the need for other tools.

[0032] Furthermore, the size of the mounting block 3 is larger than that of the nut 27, and the diameter of the through hole 31 is the same as that of the movable rod 32. The movable rod 32 is connected to the surface of the mounting block 3 through the through hole 31. The through hole 31 allows the movable rod 32 to move on its surface, and the length of the rotating arm can be maintained when the mounting block 3 is rotated.

[0033] Furthermore, two sets of threaded grooves 33 and limiting blocks 34 are provided. The two sets of threaded grooves 33 are opened at both ends of the movable rod 32, and the two sets of limiting blocks 34 are installed at both ends of the movable rod 32. The diameter of the limiting blocks 34 is larger than the diameter of the through hole 31. The threaded block 35 is threadedly connected to the surface of the threaded groove 33. Under the action of the limiting block 34, the movable rod 32 can be limited to prevent it from falling off the mounting block 3 during the rotation of the movable rod 32. At the same time, with the connection between the threaded block 35 and the threaded groove 33, the movable rod 32 can be disassembled and replaced.

[0034] Working principle: After the axial flow fan is installed and fixed by the mounting plate 14, the outer shell 1 is pushed and rotated around the connecting column 24 under the limiting connection of the mounting chamber 21 and the rotating plate 25. The connecting column 24 rotates on the surface of the connecting hole 22 and drives the rotating plate 25 to rotate on the inner surface of the mounting chamber 21 and the surface of the connecting plate 2. At the same time, the screw 26 slides along the surface of the movable groove 23. After the angle is determined, the nut 27 is threaded onto the screw 26 and tightened so that it abuts against the mounting chamber 21.

[0035] When tightening nut 27, first insert movable rod 32 into through hole 31 and through mounting block 3. Then place two sets of limiting blocks 34 at both ends of movable rod 32 and align threaded block 35 with threaded groove 33. At this time, rotating limiting block 34 will allow threaded block 35 to be threaded onto threaded groove 33. Then pull movable rod 32 to make one set of limiting blocks 34 abut against mounting block 3. Finally, hold movable rod 32 and rotate it with screw 26 as the center. When the rotation of movable rod 32 is blocked by connecting post 24, pull movable rod 32 again to make another set of threaded blocks 35 abut against mounting block 3. Repeat this several times to complete the tightening of nut 27.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
