Description
Technical Field
The utility model relates to labor protection articles, in particular to a noise-reducing safety helmet capable of reducing noise and protecting hearing.
Background
The safety helmet can play a better role in protecting the head of a person from injury caused by falling objects and other specific factors, and is a necessary labor protection tool in various construction processes. However, the common safety helmet can only play a role in protecting the head, and can not play a role in protecting noise on construction sites with huge noise such as industrial and mining enterprises. The continuous huge noise is very harmful to human body. The hearing aid is exposed to intense noise for a short time, is harsh in sound, causes discomfort to a human body, and is reduced in sensitivity after the noise passes. Prolonged exposure to or multiple exposure to strong noise can cause significant hearing loss and can cause permanent damage to hearing.
The existing safety helmet with the noise reduction function achieves the purpose of noise reduction by simply adding a sponge sound absorption layer, and the noise reduction effect is poor. And have the initiative function of making an uproar, for example, the publication is CN211703626U, and the name is a safety helmet for construction, adopts the initiative mode to make an uproar falls, and the noise reduction effect is better. However, the portable electric power source has the problem of high manufacturing cost, and the power source needs to be charged frequently, so that peripheral accessories are more, and the portable electric power source is more cumbersome to carry. The connecting wires at the periphery of the electronic device are easy to damage in the operation process, and once no electricity or lines are damaged, the standing horse loses the noise reduction protection.
Disclosure of Invention
The technical problems to be solved by the utility model are as follows: aiming at the problems, the noise-reducing safety helmet is simple in structure, low in manufacturing cost and good in noise-reducing effect.
The technical scheme of the utility model is as follows: the utility model provides a safety helmet of making an uproar falls, includes cap shell, cap lining and chin area, be fixed with oval earmuff of making an uproar falls through the elastic support on the cap shell, the earmuff of making an uproar falls includes housing, noise elimination box and earmuff, the housing back is equipped with elastic support connecting portion, the housing passes through elastic support connecting portion and is connected with the elastic support, the noise elimination comprises box body and lid, the box body is cut apart into a plurality of cell that is used for the noise elimination by the baffle, the height of baffle is less than the lateral wall all around, one side of lid is equipped with a plurality of picture peg and cell one-to-one, the picture peg inserts in the cell after lid and the box body lock forms circuitous tortuous noise elimination passageway in the noise elimination box, the front and the back of noise elimination box are equipped with the sponge layer respectively, the earmuff comprises annular sponge circle and Mongolian cloth, the Mono cloth wraps outside the sponge circle and leaves the shirt rim of pocket to one side, the earmuff is arranged in the front of noise elimination box, its shirt rim wraps at noise elimination box edge, the back of the casing is fixed and the shirt rim of the earmuff is kept down to the earmuff.
The utility model has the technical effects that: the noise-reducing device has the advantages of simple structure, low manufacturing cost, reasonable design, good noise-reducing effect and convenience in use and carrying, and can provide continuous protection effect on noise only by wearing.
