Description

Comfortable bandeau with large opening

Technical Field

The utility model belongs to the technical field of the industrial mask, concretely relates to big uncovered bandeau of half face guard adaptation of industry.

Background

The dustproof half mask is an operation protective article, aims to prevent or reduce dust in air from entering human respiratory organs, ensures the health of human viscera, and is often applied to an operation environment with more dust. The dustproof half mask needs to be worn correctly (without leakage) in each wearing position during use, and must be worn consistently in dust collection operation. In long-term use, if the wearing is uncomfortable, the head band length is not allowed to be changed without permission, or the nose clip is loosened. Therefore, the good half mask not only ensures air tightness after being worn, but also ensures the comfort and durability after being worn for a long time.

Especially, in the process of using the half mask in the dust receiving environment with high-concentration dust such as industrial and mining, grinding, metallurgy and the like, the dust mask must be worn all the time. When the safety helmet works in an environment with high dust concentration, noise and high temperature are generated at the same time, so that the working area is far away from a rest area, and the safety helmet is not required to be taken off in the working environment. The general working time of this kind of operational environment is longer, when wearing half face guard and safety helmet for a long time, the safety helmet can oppress the bandeau gradually, and along with time lapse, the bandeau can cause strong oppression to the person's head, causes the head discomfort, causes the circumstances such as headache.

At present, the joint of most bandeams and elastic bands in the market adopts a split padlock, the tensile strength of the joint is low, and a connecting piece is easy to damage and inconvenient to replace. In addition, the overall angle of the elastic band when pulling the headband is particularly easy to affect the comfort of the wearer wearing the glasses; some headband straps not only snap into the glasses, but even snap into the ears.

The sizes and the shapes of the heads of users are different due to different heights, so most of the head bands on the market have the corresponding size adjusting function, but the effect is very little after the head bands are actually adjusted. And because the headband is soft, no hardness exists; or the head band is hard to press the head, and the head band can be broken in severe environments such as winter, and the like, and the product is seriously deformed, so that repeated use is influenced.

SUMMERY OF THE UTILITY MODEL
