Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, Figure 2, Fig. 3, shown in Fig. 5, Fig. 6 and Fig. 7, the chin front air port wind direction switching device of the present embodiment, including mounting seat 1, first gear door 2, second gear door 3 and lid shell 4.In mounting seat 1, processing has first opening 11 and two the second openings 12, and wherein the first opening 11 is located between two the second openings 12.First gear door 2, second gear door 3 and lid shell 4 are installed in mounting seat 1 successively, and second gear door 3 covers in the first opening 11 and two the second openings 12.The opening or close and make the first opening 11 and two the second openings 12 open or close of second gear door 3.First gear door 2 can move thus opening or close the first opening 11 in mounting seat 1.
Optimal technical scheme, on second gear door 3, processing has a connection lid 31, and in this connection lid 31, processing has mounting groove.Being fixed with cross bar in mounting seat 1, mounting groove clamping cross bar is thus being installed in mounting seat 1 by second gear door 3, and second gear door 3 swings around cross bar thus realizing opening or closing the action of the first opening 11 and the second opening 12.
Optimal technical scheme, in mounting seat 1, processing has gathering sill, on first gear door 2, processing has the guide plate 21 matched with gathering sill, and this guide plate 21 is set in gathering sill, and guide plate 21 has the promotion projection 22 for promoting first gear door 2 away from the processing of first gear door 2 place.Promote projection 22 so that the action of the first opening 11 is opened or closed in guide plate 21 mobile realization in gathering sill.
With reference to Fig. 4, on guide plate 21, also processing has draw-in groove 211, and this draw-in groove 211 is through on the thickness direction of guide plate 21, and it is big that the width of draw-in groove 211 is middle little two ends.On guide plate 21, the both sides place of draw-in groove 211 has processed groove 212 respectively, and this groove 212 is through on the thickness direction of guide plate 21.On lid shell 4, processing has projection 41, and the draw-in groove 211 of guide plate 21 is set on this projection 41.
Below the operation principle of chin described in the utility model front air port wind direction switching device is described in further detail.
With hands, second gear door 3 is moved, and press downwards promotion projection 22 with hands and open the first opening 11, now as shown in Figure 8, first opening 11 and the second opening 12 are opened, wind enters in the helmet from the first opening 11 and the second opening 12 respectively, wherein the first opening 11 just face to helmet wearer, and the wind entered from the first opening 11 flows to the face of wearer, thus improving the breathing smoothness of wearer and improving comfortableness, mask wearer is evolved mist by the wind entered from the second opening 12.When not being required to be face air-supply, being pushed to by promotion projection 22, now first gear door 2 closes the first opening 11, and wind only enters from the second opening 12, and to mask wearer evolution mist.When not in use, second gear door 3 is closed, now close the first opening 11 and the second opening 12.
Chin of the present utility model front air port wind direction switching device, it can switch the air intake wind direction in the front air port of chin of the helmet, improve the multiformity of the air intake wind direction of the helmet, owing to the changeable face for wearer carries wind, the breathing smoothness that improve wearer and the comfortableness worn.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
