The bonding strength and stability of rigid fastener 3.
It is preferred embodiment that all connectors are uniformly distributed in the mask body 1.
In the present embodiment, connector is uniform in mask body 1 so that when mask body 1 is contacted with human face, institute
The dynamics relative equilibrium of application, it is ensured that the comfort level of face, and ensure that sealing property.
It is preferred embodiment that the connector includes the second length adjuster 8 and fixed fastener 2；
The left and right ends of the elastic fastening device 6 are connected by the fixed fastener 2 with the mask body 1；
The upper end of the rigid fastener 3 is connected by the fixed fastener 2 with the mask body 1, the rigidity fastening
The lower end of device 3 is connected by second length adjuster 8 with the mask body 1.
In the present embodiment, connector be two kinds, one kind be fastener and mask body 1 are fixedly connected it is motionless
, another is to be slidably connected, length-adjustable.Breathing mask of the invention is so enabled to be applied to more
Crowd.
In the present embodiment, elastic fastening device 6, being capable of opening to mask body 1 due to itself having certain elasticity
Clamp force is adjusted, therefore, when its two ends is connected with mask body 1, using the fixed mode of fixation fastener 2；Rigidity fastening
Device 3 is because itself is without elasticity, and it is correspondingly suitable for use in more crowds, it is necessary to which its length, position etc. are adjusted.
It is adjusted by the second length adjuster 8 in the present embodiment, reach the regulation to rigid fastener 3.
In the present embodiment, the second length adjuster 8 is arranged on the lower section of rigid fastener 3, can be conveniently
Second length fixator is used.
It is preferred embodiment that second length adjuster 8 is watchband type length adjuster.
In the present embodiment, the second length adjuster 8 is watchband type length adjuster, that is to say, that length adjuster
One end is fixing end, and the other end is adjustable side, after fixing end is extend into adjustable side, is adjusted by adjustable side so that fixed
The length at end changes, and then realizes the regulation to length.
It is preferred embodiment that breathing mask also includes headgear 7；
The headgear 7 is tightly connected with the mask body 1；
The headgear 7 is arranged on the rigid fastener 3 close to the side of the mask body 1.
In the present embodiment, headgear 7 is provided with breathing mask, when in use, first head is extend into headgear 7, then
Mask body 1 is corresponding with the face of human body, rigidity fastening is filled by first fastener 4 and second fastener 5 afterwards
Put 3 and the fixation of elastic fastening device 6.
From the above, it is seen that the breathing mask of the present invention is main by mask body 1, two rigid restraint zones（Rigidity is tight
It is fixedly mounted with and puts 3）With an elastic band（Elastic fastening device 6）Sew and constitute in center section.Wherein rigid restraint zone includes tensioning
Rope, two tensioned lines, which are intersected, is placed, and middle exposed portion is fixed with a spring cord lock or length adjuster.The outside of elastic band
It is sewed with a larger VELCRO of area.Six terminations of two rigid restraint zones and an elastic band formation respectively with mask sheet
Body 1 is connected, wherein rigid restraint zone two upper ends and elastic band two ends totally four terminations with fixed fastener 2 and mask
Body 1 is connected, and two lower ends of the rigid restraint zone mode of totally two termination length adjusters and mask body 1 in addition
Connection.Fastener on the fixed garment-like of fastener 2, by a face is detained, a pair of double buckles and a clasp nail are constituted.
Wearer is taken after breathing mask, first ensures that VELCRO is opened, and send the first transaction of a day's business tight rope, then headgear 7 from below
Opening wears breathing mask.Mask body 1, which is applied to after face, locks tensioned lines by spring cord lock, makes mask body 1 abundant
Fitted with face.Finally clinged using VELCRO in outside, then wear completion.Two length adjusters of the lower section of mask body 1
Operation is not usually required to, only directly wears when mask can not adjust suitable and operates again in wearer.
The chemical oxygen breathing mask of this multiple Quick fastening, solve in the market breathing mask wearing mode it is cumbersome, wear
The problem of wearing time length, poor sealing, is that trapped personnel has striven for the time in escape from fire, while good airproof performance is also stranded
Personnel create independent good breathing condition.
The breathing mask that the present invention is provided, is carried out mask body 1 by rigid fastener 3 and elastic fastening device 6
It is fixed, then tightened up by first fastener 4 and second fastener 5, realize and fast wear, reduce needed for wearing
The time wanted, and due to at least six contact points of mask body 1, it is ensured that sealing effectiveness, is that trapped personnel is escaped in the scene of a fire
The time has been striven in life, while good airproof performance also creates independent good breathing condition for trapped personnel.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
