Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one
It referring to Fig.1, is direction-adjustable air blower in air port disclosed by the utility model, including shell is patty and has
The first motor 2 of air blower ontology 1 and the blower work in air port, air blower ontology 1 are arranged with pedestal 3, the first electricity
Machine 2 is fixedly connected on pedestal 3, and the center of two circular side walls on air blower ontology 1 is along its axially projecting formation cylindricality
Shaft 13, the support frame 4 that 13 lower position of shaft is threaded with triangle is located on pedestal 3, shaft 13 is sheathed on branch
Above support 4, a circle driving cog 5 machined on the annular sidewall of the shell of air blower ontology 1, driving cog 5 is avoided where air port
Position is arranged, and is fixedly connected with the second motor 11 on pedestal 3, second gear 7 is coaxially connected on the output shaft of the second motor 11, the
Two gears 7 are meshed setting with driving cog 5.
When needing to adjust the angle in air port, start the second motor 11, second gear 7 is driven to rotate, second gear 7 and drum
Driving cog 5 on the annular sidewall of the shell of fan body 1 is meshed, therefore is able to drive the air blower sheet where driving cog 5
Body 1 rotates, to achieve the purpose that regulating tuyere direction.When air port turns to the angle of needs, the second motor 11 of control stops
Rotation stop is dynamic, and the tooth in second gear 7 and the 5 phase clamping of driving cog on air blower ontology 1, can prevent air blower ontology 1 at this time
It rotates under the effect of gravity, influences the air port direction adjusted.
Referring to Fig.1, bearing 12 is provided between the outer wall of shaft 13 and support frame 4, the connection of bearing 12 reduces shaft
Frictional force between 13 outer wall and support frame 4 during rotation, rotates air blower ontology 1 during adjusting angle
It is more smooth, while also preferably protecting shaft 13 and support frame 4.
Referring to Fig.1, the pitch circle diameter of second gear 7 is less than the pitch circle diameter of driving cog 5, and this setup makes
Second gear 7 not only plays the role of passing movement with engaging for driving cog, additionally it is possible to slow down in transmittance process, make to rotate
Movement becomes slowly when being transmitted on air blower ontology 1 from the output shaft of the second motor 11, slow adjust tuyere angle with this
It is slow and steady, convenient for control.
Since air blower ontology 1 has the side in air port heavier, the center of gravity of air blower ontology 1 not at its center, compared with
The side of weight has the trend rotated down when the second motor 11 stops, and only relies on engaging for second gear 7 and driving cog 5
It is larger to the flank of tooth damage of the position of engagement to bear the power that this part generates, therefore, referring to Fig.1, this embodiment of the utility model
It is drilled with first pin hole of circle 6 between in the circular side wall of middle 1 side of air blower ontology, is close to air blower ontology 1 on pedestal 3 and is arranged
It is fixedly welded with convex block 8 at the circular side wall of first pin hole, 6 side, is drilled on convex block 8 and is distributed the of circle by first pin hole 6
Two pin holes 9 plug backing pin 10 between first pin hole 6 and the second pin hole 9.
The first pin hole 6 and the second pin when air blower ontology 1 turns to the approximate angle of needs, near rotational angle
Backing pin 10 is plugged between hole 9, thus by air blower ontology 1 since the power that centre-of gravity shift generates is shared on backing pin 10, certain
Second gear 7 and driving cog 5 are protected in degree.
Embodiment two
Referring to Fig. 2, the embodiment two of direction-adjustable air blower in air port disclosed by the utility model and the knot of embodiment one
Structure is essentially identical, the difference is that: it is fixedly connected with first gear 51 in the circular side wall of 1 side of air blower ontology, is driven
Tooth 5 is the tooth in first gear 51.
Finished gear during fabrication, is directly fixed to the circle of 1 side of air blower ontology by air blower in any way
On side wall, without considering the problems of that driving cog 5 and blower drum are integrally machined, easy to process, cost is relatively low.The setting
Application method be the same as example 1.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
