The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Referring to Fig. 1 and Fig. 2, a kind of airduct can be made level and adjust flexible blower, comprises casing 1 and airduct, is provided with motor, fan blade etc. in casing 1, and this part-structure is same as the prior art, does not repeat them here.
Airduct comprises that the first airduct 2 and the second airduct 3, the first airducts 2 are connected with casing 1, and two airducts link together by telescopic socket join structure, can relatively move.The second airduct 3 is arranged in the first airduct 2, and the both sides that the both sides of the first airduct 2 are respectively equipped with guide groove 23, the second airducts 3 are respectively equipped with guide rail 34 (arranging of guide rail and guide groove can be exchanged).
The first airduct 2 comprises managing on first manages 21 and first time pipe 22 on 21 and first time pipe 22, the first and comprises respectively two semicircle pipelines that are arranged side by side, and docking snaps into one and forms the first airduct 2 up and down.The end centre position of the first airduct 2, the connecting portion of two semicircle pipelines is provided with the button frame 5 of button 4 and navigation button 4, button frame 5 comprises being positioned at manages the first on 21 on first, the outside end opening of this part inserts for button 4, and being positioned at the second portion on pipe 22 first time, the outside one end of this part is sealed.
Button 4 is rectangle, partial insertion is in button frame 5, and its one end being inserted in button frame 5 is provided with the end wall 42 that is highly greater than sidewall 41, and end wall 42 is provided with axle 43, one end of back-moving spring 44 is set in outside axle 43, one end butt of the other end and 5 sealings of button frame.The sidewall 41 of button 4 is provided with to the button guide rail 45 of button frame 5 inside wall projections, is formed with button guide groove 51 on the inside wall of button frame 5, and button guide groove 51 closed at both ends, to continue slip after avoiding button 4 to put in place.
The second airduct 3 comprise left and right be arranged side by side cylindrical second on manage 31 and second time pipe 32, the position of managing the connecting portion corresponding button 4 of 31 and second time pipe 32 on above-mentioned second is provided with axially extended tooth bar 33, has a plurality of spaced apart latches 331 (seeing Fig. 3 and Fig. 4) on tooth bar 33.
Referring to Fig. 3, it is the lock-out state of the first airduct 2 and the second airduct 3, now, the end wall 42 of button 4 is between two latches 331 of tooth bar 33, the interval of its width and latch 331 is adaptive, with two latch 331 butts, make the first airduct 2 and the second airduct 3 lock and can not relatively move, the end butt of button guide rail 45 and button guide groove 51 respectively.
Referring to Fig. 4, in the time need to regulating the relative position of two airducts, to press button 4 presses in button frame 5, now, back-moving spring 44 is compressed, latch 331 is moved to avoid to the blind end of button frame 5 in the position of end wall 42, and sidewall 41 is moved into place between two latches 331, due to the height of sidewall 41 height lower than end wall 42, latch 331 and sidewall 41 do not have overlapping part in the vertical, sidewall 41 can not with latch 331 butts, make thus the second airduct 3 can be relative the first airduct 2 slide.Because latch 331 has a plurality of, can slide into desired position according to operator's height, after this release button 4, under the restoring force effect of back-moving spring 44, button 4 moves to the openend of button frame 5, until button guide rail 45 moves to the end butt with button guide groove 51, end wall 42 moves between two latches 331 and butt again, to avoid two airducts to relatively move.Referring to Fig. 5, for the view after airduct contraction, upper from figure, after two airducts contractions are adjusted and locked, whole distance greatly reduces, same, also two airducts can be trailed relatively, whole distance is strengthened, to adapt to different users.
The foregoing is only preferred embodiment of the present utility model; it should be pointed out that for the ordinary skill in the art, do not departing under principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
