Description
Technical field
The application is related to a kind of rescue respirator.
Background technology
In building fire, smog is to hinder people's escape, causes trapped personnel main causes of death.
When fire occurs for building, the infringement in order to avoid smog to people, particularly forest fire, fire hazard aerosol fog are huge,
Huge threat is brought to fire-fighting and rescue team member and escape personnel, current fire-fighting and rescue personnel besiege people in rescue by fire hazard aerosol fog
Most of or by fire-fighting air tank combination fire mask use during member, but carry fire-fighting air tank inconvenience and can not
It is supplied to many people to use, the dedicated air tank that fire fighter carries sometimes can not also meet the rescue of oneself and use, let alone
Meet the trapped personnel of scene of fire.Equally, factory building is big, how for a long time emporium, high building is equally existed when occurring fire
Meet the demand of the air of fire fighter and escape personnel's breathing.
Prior art has revealed that the definition of slide fastener, and slide fastener is the flexible tooth chain belt engaged each other by two and can repeat it
Pulled open, the connector of the composition such as the pull head of drawing.Slide fastener can be divided into three series：Metal, nylon, glue tooth (injection)；Even
Continuous shaping：Nylon；Single shaping：Metal (punching press), glue tooth (injection).Classify by material：Metal material is divided into aluminum and copper；
The material of nylon is monofilament polyester；The material of glue tooth is mainly polyformaldehyde (acefal homopolymer and copolymerized methanal).The work of slide fastener is former
Reason be usually with make a concerted effort and component principle explanation：When unziping, the object of triangle is started shipment in two interchains and slide fastener one
Dynamic, the pulling force of hand generates two component on triangle, and in the case of angle very little, the power acted on wedge angle is very
Greatly, two component to slide fastener exert a force and component be more than straight down make a concerted effort, i.e., component be more than hand pulling force, so it is difficult to directly dividing
The slide fastener left is easily separated by triangle.Alternatively slide fastener is also known as zip, be a repeatable drawing, pull open by
Two it is flexible can intermeshing connector, it is one of most important invention in the world, common slide fastener over more than 100 years
Form has single head to close tail formula, double end to close tail formula, double end tail-splitting type etc..The principle of slide fastener be make use of one it is simple and mechanical --- tiltedly
Face, is also wedge.You can feel very easily, because being labour-saving using inclined-plane, but directly to be nibbled slide fastener with hand when pulling with hand
Close, be very difficult.When Egyptian builds pyramid within 2500 before the Christian era, i.e., huge stone is moved using inclined-plane.
Though inclined-plane was used by a person as long as several centuries, when 1586 this base of a fruit literary talent advance a theory on explanation, when an object is along one
When smooth bevel is pushed up, the power needed for being brought up to beveled top end is F=wh/d, and wherein F is that parallel what bevel direction is applied
Plus the external force of what object, W is thing weight, the height on h foots inclined-plane, and d is chamfer length.Outside inclined-plane is reduced needed for raising object
Power, because inclined-plane has mechanical advantage, i.e. d/h ratios.Inclined-plane is gentler, and mechanical advantage is bigger.Slide fastener is also the one of incline applications
Kind, inclined-plane makes the small strength zipped be converted into being enough the great power of division sprocket.Pull head be it is one large one small, a little
As ship shape, there be a central term tongue centre of stub end, during closed zipper, and a pair pairs of lock teeth are directed into microcephaly, by small
Head by forcing lock tooth mutually to be detained in pairs.When opening slide fastener, central term tongue at major part by pushing up out or opening lock tooth in pairs,
The lock tooth of opening is guided to major part, i.e., separated to both sides.
