In being discussed in more detail below, with reference to the accompanying drawing of the part of this description of formation, wherein, showing in an exemplary manner and can implement specific embodiment of the utility model.About figure, such as " top ", " end ", " interior ", " outward " directional terms use with reference to the direction of described accompanying drawing.Because the assembly of the utility model embodiment can be placed on many different directions, thus direction term only for illustration of, and without any restriction the meaning.It should be understood that and can use other embodiment, and can structure or logical changes be carried out under the prerequisite not deviating from scope of the present utility model.So, be described below in detail and should be understood to the restrictive meaning, and the utility model is defined by the appended claims.
It should be understood that the feature of different exemplary embodiment described herein can be bonded to each other if do not have other dated especially.
Fig. 1 shows the different piece of the helmet 10 according to breathing mask 100 of the present utility model, and wherein the helmet 10 comprises helmet shell body 11 and helmet inner housing 12.This helmet 10 can fit together with the face shield 20 of the breathing mask 100 shown in follow-up Fig. 2 the breathing mask 100 formed in Fig. 3.
Fig. 2 shows according to the utility model face shield 20, and it can be pivotally mounted on the helmet 10 shown in Fig. 1.Face shield 20 comprise face shield shell body 21 and face shield inner housing 22.According to the utility model, face shield shell body 21 and the helmet inner housing 12 shown in Fig. 1 link together.
As shown in FIG. 3, in the state assembled of breathing mask 100, two end clips be positioned on face shield shell body 21 of face shield 20 are held on the both sides being positioned at helmet inner housing 12 of the helmet 10, and face shield 20 and the helmet 10 are fixed together respectively by detent mechanism 60.For the ease of the position of adjustment face shield 20 relative to the helmet 10, the join domain 1 of the helmet 10 and face shield 20 is usually located near the ear region of wearer.Detent mechanism 60 comprises spring part 61 (see Fig. 5 c) and alignment pin 62, and the inner surface configuration of face shield 20 is pressed on the outer surface of the helmet 10 from outside by spring part 61 by alignment pin 62 ordinatedly.Face shield 20 in use can manually lift by wearer, and therefore face shield 20 is that the center of circle is towards the helmet 10 pivotable step by step with alignment pin 62.This design makes the helmet 10 of breathing mask 100 to be closely worn on the head of wearer, and face shield 20 can lift an angle relative to the helmet 10 pivotally at every turn, such as 30 °, and remains on this position.In category of the present utility model, face shield 20 can be identical relative to the angle that the helmet 10 lifts at every turn, also can be different.
Composition graphs 4 and 5a-5c can find out, in order to realize being lifted relative to the helmet 10 pivotable by face shield 20 step by step, and remain in corresponding position, governor motion 70 is comprised especially according to breathing mask 100 of the present utility model, it comprises the Wavelet piece 71 of the annular on the outer surface being arranged on helmet inner housing 12, and is arranged on the corresponding Wavelet piece 72 matched with Wavelet piece 71 on the inner surface of face shield shell body 21.When the adjacent crest of Wavelet piece 71 and corresponding Wavelet piece 72 or adjacent trough just the same time, face shield 20 lifts identical angle relative to the helmet 10 at every turn.On the contrary, when the adjacent crest of Wavelet piece 71 and corresponding Wavelet piece 72 or adjacent trough not identical time, face shield 20 lifts different angles relative to the helmet 10 at every turn.
Annular Wavelet piece 71 relative to the convex outer surfaces of helmet inner housing 12, and is provided with a circular open 4 in the join domain 1 of helmet inner housing 12, and it constitutes a part for the through hole that can be run through by alignment pin 62 in this as pilot hole.
Fig. 5 a shows the partial enlarged drawing of inner surface at join domain 1 that face shield shell body 21, Fig. 5 b shows face shield shell body 21, and Fig. 5 c illustrates the partial enlarged drawing of the outer surface of face shield shell body 21 at join domain 1.Clearly can identify thus, the inner surface of face shield shell body 21 towards breathing mask 100 inside is provided with corresponding Wavelet piece 72 and another circular open 4.This corresponding Wavelet piece 72 is protruding relative to the inner surface of face shield shell body 21.Face shield 20 has the annular protrusion 2 extended from the outer surface of face shield shell body 21, and the inner peripheral surface of this annular protrusion 2 and the outer surface of alignment pin 62 limit the container cavity 3 holding spring part 61.
The face shield 20 illustrated in fig. 5 c is assembled with detent mechanism 60.Because spring part 61 is contained in container cavity 3 (see Fig. 5 b) with being pre-compacted, alignment pin 62 comprises end face 621 and the column 622 extended as this end face 621 that hangs down, and is wherein designed to wavy spring part 61 and is enclosed within the outside of column 622 and is blocked by end face 621.Therefore, together with Wavelet piece 71 can being pressed on corresponding Wavelet piece 72, thus ensure that face shield 20 can not rotate relative to the helmet 10 because being subject to gravitation when lifting and glide.
End face 621 is provided with the identification piece 625 that can dismantle, thus is convenient to wearer and accurately identifies oneself exclusive breathing mask 100, the user friendly of breathing mask 100 can be increased thus.
Fig. 6 shows the detail view of detent mechanism 60.Column 622 is made up of multiple axially extended section, limits the breach 624 as predeformation space between each section.Radial stop flange 623 of extending from the side face of column 622 is formed with away from the side of end face 621 (see Fig. 5 c) at column 622.Under the state shown in Fig. 3, these stop flange 623 are positioned on helmet inner housing 12 inner surface, and and helmet inner housing 12 on around opening 4 arrange locking groove 6 (see Fig. 1) form fit be fixed together.
In unshowned assembling process, face shield 20 can be clamped in the helmet 10 both sides by assembler, opening 4 on face shield shell body 21, corresponding Wavelet piece 72 being alignd with the opening 4 on helmet inner housing 12, Wavelet piece 71, forming the through hole for making the column 622 of alignment pin 62 pass thus.The column 622 of spring part 61 is had to be pressed into through hole from breathing mask 100 outside by cover subsequently, spring part 61 is clamped between the end face 621 of face shield 20 and alignment pin 62, and the stop flange 623 of alignment pin 62 radially-inwardly compress ground through in the locking groove 6 of kayser in helmet inner housing 12 after through hole.
In order to improve the dismounting flexibility of breathing mask 100, alignment pin 62 can be made by having flexible plastics.
In addition, Wavelet piece and the helmet can be made into integration.Same corresponding pieces and face shield also can be made into integration.
In another embodiment, Wavelet piece and corresponding pieces can be the parts be additionally arranged on respectively on the helmet and face shield.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
