Description

Mine sweeping protective helmet

Technical Field

The utility model relates to a sweep mine protection apparatus field, concretely relates to sweep mine protection helmet.

Background

In war time, mines play an important role. However, mines are not limited to the war period, and since mines are buried underground and are not easy to be found, countless people are killed within tens of years after the war, and the land cannot be used and used within tens of years.

Therefore, the need for sweeping the mine is very high. When in mine sweeping, in order to protect the life health of mine clearance personnel, the mine clearance personnel must wear a helmet. However, the existing helmets are heavy and are easy to cause discomfort to the head and neck after being worn for a long time. Meanwhile, when the mine explodes, the generated shock waves act on the human body at a speed of 300 m/s, the acting force, the weight of the head and the helmet are overcome by the neck, and therefore huge damage to the cervical vertebra of mine clearance personnel is inevitably caused. Therefore, the weight of the helmet is reduced, and the helmet has important significance for reducing the pressure on the head and the neck of a mine clearance worker, reducing the damage to cervical vertebra and vertebra, facilitating the flexible movement of the mine clearance worker and improving the mine clearance efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is anticipated to provide to sweep the thunder protective helmet to alleviate the weight of helmet.

In order to achieve the above purpose, the utility model adopts the following technical scheme: sweep thunder protective helmet, including the helmet body and face guard, the face guard is located the front side of the helmet body, and the face guard includes double-deck panel, double-deck panel integrated into one piece, has the space between the double-deck panel.

The principle and the advantages of the scheme are as follows: the face guard is used for protecting the face, and the helmet body is used for protecting the head, so that the helmet body and the face guard form a complete protection system to protect the head and the face of a wearer. Because the face guard is double-deck plate structure, has the space between the double-deck plate, under the equal thickness condition with current face guard, the material of face guard that can significantly reduce is set up in the space to alleviateed the weight of face guard, alleviateed whole sweeping mine protection helmet's weight, be favorable to alleviateing escape personnel's head, neck pressure, reduce the injury to cervical vertebra.

Meanwhile, the face mask is designed to be of a double-layer structure, when the outer layer of the plate is damaged by impact, the inner layer of the plate can also play a role in protection, so that the protection performance of the face mask can be guaranteed while the weight of the face mask is reduced.
