Abstract
The utility model relates to a soft and hard material composite aviation oxygen mask main body. The soft and hard material composite aviation oxygen mask main body comprises a hard cavity playing a supporting role and is characterized by further comprising a soft flanging frame playing the role of clinging to a face, and the soft flanging frame and the periphery of the hard cavity are composited in all directions. Further, the preferable scheme of the soft and hard material composite aviation oxygen mask main body is that the hard cavity is made of silicone rubber of Shore A harness of 50-60; the soft flanging frame is made of silicone rubber of Shore A harness of 20-30; the all-directional composite mode of the soft flanging frame and the periphery of the hard cavity is a glue injection molding composite mode or a gluing composite mode of the two materials. The soft and hard material composite aviation oxygen mask main body can eliminate sense of pressure on the face after a user wears the aviation oxygen mask main body and greatly improve comfort level during usage.
Description
Technical field
This utility model relates to a kind of oxygen face mask, particularly relates to a kind of by the compound aviation oxygen face mask main body of soft or hard material.
Background technology
Aviation oxygen face mask is the safety device of aviation driver and crew indispensability.Known aviation oxygen face mask guarantees support stiffness because of needs, so its cavity adopts the relatively high silastic material of shore a hardness to make, but also exist significantly not enough simultaneously, the one, the face that hard aviation oxygen face mask is worn user of service easily produces constriction, the time of wearing is more of a specified duration, and its comfort level is lower.The 2nd, aviation oxygen face mask is to use under case of emergency, if wear the discomfort of rear generation, can not clear up as early as possible, will bring stewed emotion to user of service, to unruffled be located in reason case of emergency very unfavorable.Therefore, how to overcome the deficiency that prior art exists and become one of difficult problem urgently to be resolved hurrily in current safety protective tools field.
Summary of the invention
The purpose of this utility model is to provide a kind of by the compound aviation oxygen face mask main body of soft or hard material for overcoming the deficiencies in the prior art, this utility model can be cleared up aviation oxygen face mask user of service is worn to the constriction that rear face produces, and has greatly increased the comfort level in using.
A kind of by the compound aviation oxygen face mask main body of soft or hard material according to what the utility model proposes, comprise passive hard cavity, characterized by further comprising the soft flange frame of face's closely sealed effect in position, the periphery of this soft flange frame and hard cavity is comprehensive compound.The further preferred version of this utility model is: the material of hard cavity is the Shao Er A silicone rubber of hardness 55 ± 5; The material of soft flange frame is the Shao Er A silicone rubber of hardness 25 ± 5; The periphery of this soft flange frame and hard cavity is comprehensive, and to be complex as the injecting glue molding of this bi-material compound or gluing compound.
Operation principle of the present utility model is: the hot strength after the molding of general single kind silicon rubber vulcanization is in 10MPa left and right, the hot strength of soft or hard material composite surface, because the difference of material structure characteristic drops to 8MPa left and right, can meet the instructions for use of aviation oxygen face mask.Therefore, this utility model is set to soft flange frame by the closely sealed frame at architrave position, be compound in the periphery of hard cavity, so both can make the hard cavity of aviation oxygen face mask main body there is good support stiffness, the closely sealed frame that can guarantee again aviation oxygen face mask main body architrave position has preferably outwards ductility when wearing pressurization, thereby plays the effect that architrave is soft comfortable.
This utility model compared with prior art, its remarkable advantage is: the one, and aviation oxygen face mask main body of the present utility model has good ductility, when wearing, user of service longitudinally has good telescopicing performance, constriction after greatly reducing user of service and wearing, has improved the comfort level in using greatly.The 2nd, aviation oxygen face mask main body is used under case of emergency, and this utility model will bring user of service a kind of safe and reliable sense, to unruffled be located in reason case of emergency very favourable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the compound aviation oxygen face mask main body of a kind of soft or hard material that the utility model proposes.
Fig. 2 is the structural representation of the soft flange frame of the compound aviation oxygen face mask main body of a kind of soft or hard material that the utility model proposes.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
In conjunction with Fig. 1, the compound aviation oxygen face mask main body of a kind of soft or hard material the utility model proposes, the soft flange frame that comprises the closely sealed effect in position of passive hard cavity He Qi face, the periphery of the periphery of this soft flange frame and hard cavity is implemented comprehensive compound; Wherein: the material of hard cavity is the Shao Er A silicone rubber of hardness 55 ± 5; The material of soft flange frame is the Shao Er A silicone rubber of hardness 25 ± 5; It is compound or gluing compound that the periphery of the periphery of this soft flange frame and hard cavity is implemented the comprehensive injecting glue molding that is complex as bi-material, this utility model is to adopt injecting glue molding to be complex as good, concrete scheme is by the injection moulding in advance of hard cavity material but does not vulcanize, after injecting soft flange frame material, carry out co-vulcanization molding, this mode can make hot strength 20% left and right that declines.
The specific embodiment of the design of major parts parameter of the aviation oxygen face mask main body that a kind of soft or hard material that the utility model proposes is compound is as follows:
The material of passive hard cavity of the present utility model: the Shao Er A silicone rubber of hardness 55 ± 5, specification: length 130mm, width 115mm, thickness 2.5mm; The material that plays the soft flange frame of face's closely sealed effect in position of the present utility model: the Shao Er A silicone rubber of hardness 25 ± 5, specification: width 28mm, thickness 1.5mm.
This utility model is tested through repetition test, has obtained effect.
