Abstract
The utility model discloses an adjustable ear protector, which comprises an air valve and air bags. The adjustable ear protector is characterized in that the air valve (3) is mounted at the upper end of an arc elastic hollow tube (1) through a connecting tube (2), steel ball one-way valves (11) are mounted in the connecting tube (2) under the valve body, a metal connector (12) is respectively arranged at each of the lower ends of the arc elastic hollow tube (1), the air bags (13) are mounted at end parts, and a valve plate (14) is arranged in each of the connectors and is equipped with one deflation button (15). The utility model overcomes the defect that the preset earplugs cannot get adapted to sizes of external auditory canals, and adopts the air bags, so that the adjustable ear protector is suitable for people with various sizes of external auditory canals, and has a plurality of advantages like simple structure, remarkable noise prevention effect, convenience for use, and low production cost.
Description
Technical field
This utility model relates to the protective articles field, and a kind of more precisely adjustable principle of air bag of utilizing is protected the device of ear.
Background technology
Noise brings on the physiology and psychological harm to the people: hearing damage, the nervous system that influences the people, cardiovascular system, hormonal system, digestive system and vision, intelligence etc.If the people works and lives for a long time, can lose audition in 95 decibels noise circumstance; Even noise has only 85 decibels of people, also there is 10% people that deafness can take place; 120～130 decibels noise can make the people feel in ear pain; Stronger noise can make organon auditus suffer damage.Therefore, country works out its anti-noise and pollutes rules, protects the healthy of people, as measures such as employing sound-absorbing, sound insulation, sound barrier, vibration isolation, and make rational planning for city and architectural composition.Workman as long-term occupational post noise exposure can wear ear protector such as earplug, earmuff or the helmet.But some transience, though the high-decibel noise flashes across, very big to operator's harm, example: let off firecrackers, sports ground starting pistol, percussion drill etc., also need to use earplug, existing earplug has its weak point, and because of each one external auditory meatus differs in size, earplug elasticity is too big, can oppress skin of external auditory canal, cause discomforts such as bulge of the ear, otalgia; Elasticity is too little then can not closely to be contacted with external auditory meatus, and defening effect reduces.，
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, adaptability good, the ear protector that can regulate.
The purpose of this utility model adopts following technical measures to realize: a kind of adjustable earflap, by air valve, air bag is formed, it is characterized in that: in the upper end of arc flexible hollow tube, by connection tube, air valve is housed, described air valve: a piston is arranged in valve body, be shaped on air inlet on the piston, under the hole check valve sheet is housed, under the piston spring is housed, a montant is arranged on the piston, rod end is equipped with button, in the connection tube, the steel ball check valve is housed under the valve body, the lower end of arc flexible hollow tube, one metal union joint is arranged, air bag is equipped with in the end, and a valve block is arranged in the union joint, and a venting button is arranged on the valve block.
Remarkable result of the present utility model: owing to adopt air bag, adaptability is good, and the people who is fit to different external auditory meatus sizes uses, and is simple in structure, its anti-noise effect is remarkable, easy to use, production cost is low.
