Description
Technical field
This utility model relates to the Protection Product technology, particularly relates to a kind of elastic soft its anti-noise (sound) earmuff green technology of [also claiming elastic soft sound insulation (sound) earmuff, elastic soft ear protector].
Background technology
Hearing impairment is irreversible.In growing modern society, sound pollution is more and more serious, national governments and organize the noise abatement work of also more and more paying attention to.In people's daily life and activity in production, preventing noise ear cover just progressively is used widely, and it is a protection audition, and raising work, the learning efficiency reduce the influence of noise to physiology and psychology, promotes most economical, the solution of easy row of quality of the life.
Preventing noise ear cover all is a hard material cup cover both at home and abroad at present, and especially in the majority with the engineering plastics ABS use, there are following shortcoming and defect in this type of hard material and product structure:
1, hard material density generally big (greater than the elastomeric material density of software earmuff) can make the weight of entire product increase like this, and then increase wearer's head and neck burden.
2, the wearer is subjected to accidental shock (especially in commercial production) at cephalic region, as fall, during object strikes, the cup cover is the most outstanding position, but hard material can't cushion, and if the cup cover crashed the as easy as rolling off a log head of stabbing.
3, hard material cup cover can not be taken a breath, user wear the time slightly long time promptly can cover accumulated inside steam at cup, make the people produce feeling of oppression and heat, the obvious variation of comfortableness, unfavorable to ear's physiological health, reduce study and work efficient simultaneously.This point is very crucial, and it is to influence preventing noise ear cover to popularize the key factor of using.
4, when the huge noise of burst, traditional hard material cup cover can not absorb vibration acoustic energy well, also can't accomplish the inside and outside acoustic pressure balance of ear tympanum.When acoustic pressure acts on the tympanum inboard through oral cavity nasal cavity pharyngotympanic tube, and the tympanum outside can't obtain the effect of same sound pressure level, so very easily causes the tympanum damage, influences audition.
When 5, preventing noise ear cover was used for rest, sleep, the earmuff of hard material cup cover almost can't use.It can fill up the head height height when lying on one's side, even can press against the pain face.
6, hard material cup cover can not compression, and volume is bigger, transportation, stores inconvenience, increases cost, especially on carrying, increases burden for travelling merchants personage.
Above various shortcoming and deficiency fail effectively to be improved for a long time.The development of material science in recent years makes the professional person who is devoted to noise personal protection product research see the possibility of improving.But, select that soundproof effect is good, in light weight, good springiness, permanent deformation are little, nontoxic, tasteless, the substitution material of environmental protection, also non-easy thing need test heap of times, tests, analyzes, improve.In addition, realizing that elastomeric material is applied to this product, also is a brand-new design in configuration aspects.
The utility model content
At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provide a kind of in light weight, the big noise safety that can cushion, happen suddenly is good, the sleep travelling handy elastic soft preventing noise ear cover device.
This utility model the technical problem that will further solve provide the good elastic soft preventing noise ear cover device of a kind of comfort level of taking a breath.
In order to solve the problems of the technologies described above, a kind of elastic soft preventing noise ear cover device provided by the utility model, comprise the earmuff assemblies and the headstock that is connected left and right sides earmuff, it is characterized in that, earmuff assemblies comprises elastic soft cup cover successively, adopt inserted back-off nail to draw fixing structure to connect the base of elastic soft cup cover, the cushion that connects base, the ring-type clip slot is established at the edge of the cup cover joint face of base, be provided with at least two elongated holes in the groove, two sides are established position-limited rack by one side of cup cover joint face before and after the base, to prevent that the elastic soft cup from covering on when pushing forwards, backwards two sides and encircleing, the nail that buckles that is used to snap in the headstock is established in the position-limited rack outside; Elastic soft cup cover mouth edge is provided with the collar flange that cooperates with the base clip slot, and flange is provided with the back-off nail corresponding with base elongated hole (center), and elastic soft cup cover can be connected with base with mosaic mode.
Further, the elongated hole of described base clip slot is along the setting symmetrically of annular clip slot.
Further, two side elongated holes are smaller before and after the described base, and the back-off of two middle side parts nail is slightly less than other back-off nail before and after the elastic soft cup cover mouth.
Further, described cup cover is the cup cover of the arch back of the body.
Further, be provided with a circle reinforcement along a described cup cover mouthful outer surface.
Further, push the active ventilation folding line along what the front and rear edge of described cup cover back outer surface was established upward and downward.
Further, described elastic soft cup cover (lower end) is provided with the passage that a diameter is 2.1mm (or between 0.5 ~ 3.5mm) at least, is used for inside and outside acoustic pressure of balance and ventilation.
Further, be respectively equipped with the upper end on two arms of described " U " shape headstock and be the microscler cylindrical void of insertion end, be the width of the upper end of microscler cylindrical void greater than microscler cylindrical void, also be slightly larger than the ailhead that buckles of base, and the width of microscler cylindrical void is less than the ailhead that buckles of base, buckle the nail bar but be slightly larger than, make the microscler cylindrical void that nail can snap in the headstock easily that buckles of base.
Further, a side of the microscler cylindrical void of the described headstock is provided with positioning tooth, and what make base buckles can be in the microscler cylindrical void of the headstock convenient location of nail.
Further, circular step is established at the edge of the cushion joint face of described base, and the circular step top inwardly is provided with a circle flange, in order to block the flange of cushion outer ring correspondence; Cushion can stably be embedded on the base.
The elastic soft preventing noise ear cover device that utilizes this utility model to provide, owing to adopt elastic soft cup cover, density is less relatively, good springiness, shock-absorbing capacity is good, and the acoustic energy absorption performance is good, and compressible distortion is (when especially assembling with the collapsible headstock, volume is littler, the transportation storage cost lower, carry more convenient) etc. advantage; Two the folding line designs in cup cover surface when helping pushing active ventilation, make elastic soft cup cover along this folding line distortion, produce distortion and the slit occurs with the edge of avoiding connecting; Cup is covered with the passage of inside and outside acoustic pressure balance and ventilatory, and this aperture is passive ventilation constantly both, also can realize the active ventilation function by pushing; In addition, when running into the huge sound of burst, can realize inside and outside acoustic pressure balance.On cup cover base and headstock mounting process, adopted the quick manual installing technological hole design of the microscler cylindrical void that can snap in the headstock easily, improved production efficiency, reduced production cost (adopt the specific purpose tool mounting process in the past usually, cost height, efficient are low).
