Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, and in particular to an axial flow fan impeller structure with an adjustment device. Background Technology

[0002] Axial flow fans are those in which the airflow is in the same direction as the axis of the fan blades. They are widely used in many fields such as industrial ventilation, air conditioning systems, and mine ventilation. For example, electric fans and air conditioner outdoor unit fans are axial flow fans.

[0003] Currently, the motors of commonly used axial flow fans on the market are often fixed in a certain position and cannot be moved. This means that when installing the impeller, the motor needs to be fixed first, and then the impeller needs to be assembled outside the fan casing. After that, the assembled impeller is installed on the motor inside the fan casing. Due to the limited space inside the fan casing, the installation space is restricted, resulting in low installation efficiency. At the same time, when the impeller needs to be inspected or replaced, it is necessary to enter the fan casing again to disassemble it, which leads to low work efficiency.

[0004] Therefore, we provide an axial flow fan impeller structure with an adjustment device. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing an axial flow fan impeller structure with an adjustment device, thereby facilitating impeller installation and removal and improving work efficiency.

[0006] In view of this, the present invention provides an axial flow fan impeller structure with an adjustment device, including a fan housing, a sliding groove formed on the inner wall of the fan housing, a base slidably connected inside the sliding groove, a motor inserted into one side of the base, an impeller inserted into the output end of the motor, a screw cylinder installed at the lower end of the base, the screw cylinder sliding inside the sliding groove, a bolt threadedly connected inside the screw cylinder, the bolt extending out from opposite ends of the screw cylinder, and the bolt rotatably connected to the inner wall of the sliding groove, and a handle fixedly connected to one end of the bolt extending out from the outer wall of the fan housing.

[0007] Preferably, at least two fixing blocks are provided on the outer side of the screw barrel, the two fixing blocks are evenly distributed at corresponding positions, and the fixing blocks are fixedly connected to the base.

[0008] Preferably, the lower end of the fixed block is rotatably connected to at least two rollers, and the two rollers are symmetrically distributed.

[0009] Preferably, the sliding groove is provided with at least two slide rails, and the roller slides inside the slide rails.

[0010] Preferably, at least two sliders are symmetrically installed on opposite sides of the base, and a movable groove is formed through the inner wall of the fan housing near the slider, and the slider slides inside the movable groove.

[0011] Preferably, one end of the slider is fixedly connected to an arc-shaped plate, and an arc-shaped plate moving groove is formed on the outer surface of the fan housing near the arc-shaped plate, and the arc-shaped plate slides inside the arc-shaped plate moving groove.

[0012] Preferably, a plurality of fastening bolts are threadedly connected to one side of the arc-shaped plate, and at least two threaded grooves are symmetrically opened on the inner wall of the arc-shaped plate moving groove, and the fastening bolts are threadedly connected to the threaded grooves.

[0013] Compared with the prior art, the present invention provides an axial flow fan impeller structure with an adjustment device, which has the following advantages:

[0014] This invention uses a screw and bolts to move the motor horizontally, allowing it to move outside the fan casing. This eliminates the need for manual entry into the fan casing to install the impeller, making it easier for workers to install the impeller, reducing installation time, improving installation efficiency, and facilitating later inspection and maintenance.

[0015] This invention enables precise displacement or motion control by moving the bolt and screw cylinder via a handle. The bolt and screw cylinder have a self-locking function, and the motor can remain in the current position after the bolt stops rotating, ensuring the stability of the device during operation.

[0016] This invention reduces the friction between the base and the sliding groove by using the rolling support of the rollers, making it easier for workers to turn the handle to move the base, saving time and effort and improving installation efficiency.

[0017] This invention, with the support and limiting of the slider and the arc plate, prevents the base from tilting during movement and ensures the stability of the base during movement.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: An axial flow fan impeller structure with an adjustment device, such as... Figure 1 - Figure 4 As shown, the fan housing 1 is provided. A sliding groove 10 is provided on the inner wall of the fan housing 1. A base 2 is slidably connected inside the sliding groove 10. A motor 3 is inserted into one side of the base 2. An impeller 4 is inserted into the output end of the motor 3. A screw cylinder 5 is installed at the lower end of the base 2. The screw cylinder 5 slides inside the sliding groove 10. A bolt 6 is threadedly connected inside the screw cylinder 5. The bolt 6 extends out of the opposite ends of the screw cylinder 5 and is rotatably connected to the inner wall of the sliding groove 10. A handle 7 is fixedly connected to one end of the bolt 6 that extends out of the outer wall of the fan housing 1.

[0027] Before the fan housing 1 is installed and fixed, turn the handle 7 to rotate the bolt 6 simultaneously. Based on the threaded connection between the screw barrel 5 and the bolt 6, the base 2 moves horizontally inside the sliding groove 10. When the output end of the motor 3 moves out of the fan housing 1, the impeller 4 is installed on the output end of the motor 3. At this time, turn the handle 7 in the opposite direction to move the impeller 4 to the appropriate position. Use the screw barrel 5 and the bolt 6 to move the motor 3 horizontally, which makes it convenient for the staff to install and remove the impeller 4, reduces the installation time of the impeller 4, improves the installation efficiency, and facilitates later inspection and maintenance. The bolt 6 and the screw barrel 5 have a self-locking function. When the bolt 6 is stopped, the motor 3 can remain in the current position to ensure the stability of the device during operation. By moving the bolt 6 and the screw barrel 5 through the handle 7, relatively precise displacement or motion control can be achieved.

[0028] like Figure 1 - Figure 4 As shown, at least two fixing blocks 8 are provided on the outer side of the screw cylinder 5. The two fixing blocks 8 are evenly distributed in corresponding positions, and the fixing blocks 8 are fixedly connected to the base 2.

[0029] At least two rollers 9 are rotatably connected to the lower end of the fixed block 8, and the two rollers 9 are symmetrically distributed.

[0030] The sliding groove 10 is provided with at least two slide rails 11, and the roller 9 slides inside the slide rails 11.

[0031] When the base 2 moves horizontally, the rolling support of the roller 9 reduces the friction between the base 2 and the sliding groove 10, making it easier for the operator to turn the handle 7 to move the base 2, saving time and effort and improving installation efficiency. At the same time, the guide limit of the slide rail 11 prevents the base 2 from deviating at an angle during horizontal movement, ensuring the stability of the base 2 during horizontal movement and the accuracy of the movement direction.

[0032] like Figure 1 - Figure 4 As shown, at least two sliders 13 are symmetrically installed on opposite sides of the base 2. A movable groove 12 runs through the inner wall of the fan housing 1 on the side near the slider 13, and the slider 13 slides inside the movable groove 12.

[0033] One end of the slider 13 is fixedly connected to an arc plate 14. An arc plate moving groove 17 is provided on the outer surface of the fan housing 1 near the arc plate 14. The arc plate 14 slides inside the arc plate moving groove 17.

[0034] A number of fastening bolts 15 are threadedly connected to one side of the arc plate 14. At least two threaded grooves 16 are symmetrically opened on the inner wall of the arc plate moving groove 17. The fastening bolts 15 are threadedly connected to the threaded grooves 16.

[0035] When the base 2 moves horizontally, it drives the slider 13 and the arc plate 14 to move simultaneously. Under the support and limitation of the slider 13 and the arc plate 14, the base 2 is prevented from tilting during movement, ensuring the stability of the base 2 during movement. When the impeller 4 moves to the appropriate position, the fastening bolt 15 is turned clockwise to move it towards the threaded groove 16. Under the connection and limitation of the threaded groove 16 and the fastening bolt 15, the base 2 is further fixed and limited, preventing the base 2 from moving during the operation of the device, and further improving the stability of the device during operation.

[0036] Working principle: Before the fan housing 1 is installed and fixed, turn the handle 7 to drive the bolt 6 to rotate simultaneously. Based on the threaded connection between the screw barrel 5 and the bolt 6, and with the rolling support of the roller 9, the base 2 is driven to move horizontally inside the sliding groove 10. When the output end of the motor 3 moves out of the fan housing 1, the impeller 4 is installed on the output end of the motor 3. At this time, turn the handle 7 in the opposite direction to drive the impeller 4 to the appropriate position. After the impeller 4 moves to the appropriate position, turn the fastening bolt 15 clockwise to move it towards the threaded groove 16. After the threaded groove 16 is connected to the fastening bolt 15, the base 2 is further fixed and limited. At this time, the fan housing 1 is installed and fixed.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
