Description

A kind of ventilation slide block device of air supply pipe
Technical field
This application involves a kind of gas nozzles of air supply pipe.
Background technique
In building fire, smog is the main reason for hindering people's escape, cause trapped person dead.
When fire occurs for building, the infringement in order to avoid smog to people, especially forest fire, fire hazard aerosol fog is huge, Huge threat is brought to fire-fighting and rescue team member and escape personnel, fire-fighting and rescue personnel besiege people by fire hazard aerosol fog in rescue at present Use that is most of or relying on fire-fighting air tank combination fire mask when member, however carry fire-fighting air tank inconvenience and can not It is supplied to more people to use, the rescue that the dedicated air tank that fire fighter carries sometimes is also unable to satisfy oneself uses, let alone Meet the trapped person of scene of fire.Equally, how for a long time to be equally existed when workshop is big, fire occurs for emporium, high building Meet the demand of the air of fire fighter and escape personnel's breathing.
The prior art has revealed that the definition of zipper, and zipper is the flexible tooth chain band engaged each other by two and can make its repetition It is pulled open, the connector of the compositions such as the pull head of drawing.Zipper can be divided into three series: metal, nylon, glue tooth (injection molding);Even Continuous molding: nylon;Single molding: metal (punching press), glue tooth (injection molding).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 zipper is former Reason is usually to be explained with resultant force and the principle of component: when unziping, the object of triangle is started shipment in two interchains and zipper one Dynamic, the pulling force of hand produces two component on triangle, in the case where angle very little, acts on power on wedge angle very Greatly, two component exert a force to zipper and component is greater than resultant force straight down, i.e. component is greater than the pulling force of hand, so being difficult directly to divide The zipper left is easily separated by triangle.Alternatively zipper is also known as zipper, 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 zipper over more than 100 years Form has single head to close tail formula, double end closes tail formula, double end tail-splitting type etc..The principle of zipper be utilized one it is simple and mechanical --- tiltedly Wedge is also in face.You can feel very easily, because being labour-saving using inclined-plane, but directly to be nibbled zipper with hand when pulling with hand It closes, is very difficult.When Egyptian builds pyramid within 2500 before the Christian era, i.e., huge stone is moved using inclined-plane. As long as though inclined-plane has been used by a person 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 pushes up, power needed for being increased to beveled top end is F=wh/d, and wherein F is parallel to bevel direction and applies It is added on the external force of object, W is object weight, and the height on h foot inclined-plane, d is chamfer length.Except inclined-plane reduces needed for improving object Power, because inclined-plane has mechanical advantage, i.e. d/h ratio.Inclined-plane is gentler, and mechanical advantage is bigger.Zipper is also the one of incline applications Kind, inclined-plane makes the small strength to zip 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, the centre of stub end is there are one central term tongue, and when closed zipper, a pair of to be directed into microcephaly to lock tooth, dependence is small Head by force in pairs lock tooth mutually detain.When opening zipper, central term tongue at major part by locking tooth to opening or opens in pairs, The lock tooth of opening is guided to major part, i.e., separates to both sides.
Summary of the invention
