Description
Technical field
The utility model relates to a kind of security against fire apparatus, and particularly a kind of airtight reciprocating type chemistry produces the oxygen fire self-rescue escape device, belongs to personnel's self-help escape resist technology field.When being applicable to breaking out of fires such as hotel, singing-hall, underground commercial center, furniture store, skyscraper and the self-help escape the during accident leakage in chemical plant.
Background technology
Adopt the high-temperature resistant rubber mask to have following problem in the existing self-rescue escape device: versatility is poor, and the mask of multiple different size must be set the personnel of different head sizes; On the mask visor to overlook the angle of visual field little, be unfavorable for escape downstairs; Regenerative cartridge is threaded with being connected to of oronasal mask and airbag, and processing, use are all inconvenient.
Summary of the invention
The technical problem of the required solution of the utility model is, tower visibility poor at the versatility of mask size, visor is little, being threaded problem such as cumbersome of regenerative cartridge and provide a kind of all kinds of head dimensions airtight reciprocating type chemistry general, that tower visibility is big, regenerative cartridge is easy to connect, survivor's respiratory system is hedged off from the outer world to produce the oxygen fire self-rescue escape device;
The technical measures that solve the problems of the technologies described above are, the utility model produces the oxygen self-rescue apparatus by reciprocating type chemistry and is worn on head and fire-retardant thermal radiation resistant protective garment and is through on one's body and forms, respirator comprises head-shield, oronasal mask, regenerative cartridge, airbag and on the pressure limiting air bleeding valve, cover head-shield and the human body head appearance similar that the aluminium fabric is sewn into fire-retardant thermal radiation resistant, be provided with the headband that can tighten up head-shield at its top, outside and both sides, the bottom of head-shield is provided with the degree of tightness mouth, top is provided with the opening that coincide with visor forwardly, visor lower whorl profile is and the similar hump shape of human body eye nose shape, its periphery is connected mutually with the head-shield open circumferential, the place ahead is provided with opening and the anterior circular hole of oronasal mask socket-connects, be connected mutually through clip, oronasal mask, the hole of head-shield bottom and the upper outlet pipe of regenerative cartridge socket-connect and tighten up, the airbag upper opening is socketed on the cylindrical of outlet under the regenerative cartridge and tightens up, oronasal mask, regenerative cartridge, airbag is airtight connection; With fire-retardant thermal radiation resistant cover that the aluminium fabric makes not with the shirtfront of the protective garment of cap and foresleeve is provided with luminous or the reflecting marking bar;
The utility model has the advantages that compact conformation, volume is little, head-shield size versatility is good,, the tower visibility of visor has been enlarged, help self-help escape downstairs owing to adopted the hump shape visor.
