It is equipped among plate and is fixedly connected on the interior of rectangular fixed plate with consistent second round hole of ventilator outer diameter, the square connecting plate
Side, four sides of the square connecting plate are vertical with the square frame that is formed of being joined end to end by L shape plate respectively to be connect；The inner casing
One end and one end of square frame connect, the first circular hole edge among the other end and square connecting plate connects, the inner casing
Section fade to circle by rectangular from outside to inside.
Preferably, the interior edge lengths of the square frame are greater than the interior electrical path length of ventilator.
Preferably, the front end face corner location of the square frame is equipped with fixation hole.
Preferably, it is equipped with support frame in the ventilator, motor is fixedly mounted on support frame as described above, machine shaft connects leaf
Wheel, the axis of the shaft and the center of circle of ventilator radial section are on same horizontal line.
Preferably, the ventilator bottom is equipped with pedestal.
The utility model has structurally reasonable, high reliablity, reduces propeller fan entrance loss, improves propeller fan
Efficiency meets the advantages of vibratory impulse requirement.
Detailed description of the invention
A part of attached drawing for constituting the utility model is used to provide a further understanding of the present invention.In the accompanying drawings:
Fig. 1 is a kind of structural schematic diagram for having an area of gradual change double Shell propeller fan of the utility model.
Fig. 2 is a kind of partial cutaway view for having an area of gradual change double Shell propeller fan of the utility model.
In figure: 1, ventilator；2, ring-type fixing plate；3, rectangular fixed plate；4, inner casing；5, square connecting plate；6, square box
Frame；7, support frame；8, motor；9, impeller；10, pedestal；11, fixation hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As illustrated in fig. 1 and 2, a kind of circumference gradual change double Shell propeller fan, including ventilator 1, the ventilator 1
One end is equipped with ring-type fixing plate 2, and the other end is equipped with rectangular fixed plate 3, be equipped among the rectangular fixed plate 3 in ventilator 1
Consistent first round hole of diameter, the propeller fan further include shell and inner casing 4, and the shell includes square connecting plate 5, institute
It states to be equipped among square connecting plate 5 and be fixedly connected on consistent second round hole of 1 outer diameter of ventilator, the square connecting plate 5
The inside of rectangular fixed plate 3, four sides of the square connecting plate 5 respectively with the square frame 6 formed that joined end to end by L shape plate
Vertical connection；One end of the inner casing 4 is connect with one end of square frame 6, the first circle among the other end and square connecting plate 5
The connection of hole edge, the section of the inner casing 4 fades to circle by rectangular from outside to inside.The interior edge lengths of the square frame 6 are big
In the interior electrical path length of the ventilator 1.The front end face corner location of the square frame 6 is equipped with fixation hole 11, can be used for vertical
Installation is on the vertical plane.
It is equipped with support frame 7 in the ventilator 1, motor 8 is fixedly mounted on support frame as described above 7,8 shaft of motor connects impeller
9, the center of circle of the axis of the shaft and 1 radial section of ventilator is on same horizontal line.1 bottom of ventilator is set
There is pedestal 10, to support installation in the horizontal plane.
The air inlet position of circumference gradual change double Shell propeller fan forms double-layer structure, inner casing 4 by shell and inner casing 4
To have an area of gradual change shell, when the fixation hole 11 on the square frame 6 that propeller fan passes through air inlet shell is installed, axis circulation
The overall weight of blower applies on the shell, and propeller fan inner casing 4 carries out gas flow guiding, to realize the function point of shell
Work meets requirement of propeller fan under the conditions of vibratory impulse, has reached reduction propeller fan inlet loss, has mentioned
High propeller fan efficiency and the effect for meeting vibratory impulse requirement.
When the utility model is used, due to the out-of-flatness of track and swing, the start and stop of motor-car, propeller fan is corresponding
Vibration and impact are generated, shell and 4 double Shell of inner casing realize shell function allocation: shell is primarily subjected to external force, bilayer knot
Structure increases intensity, and inner casing 4 is circumference gradual change shell, so that propeller fan deflection under the conditions of vibratory impulse reduces, keeps away
The fracture for having exempted from 4 double Shell of shell and inner casing, reduces the vibration of propeller fan；Inner casing 4 is substantially carried out gas flow guiding, subtracts
Few propeller fan inlet loss improves propeller fan efficiency.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
