Technical Field

The invention belongs to the field of shoemaking, and particularly relates to a military lightning protection boot worn in ground operation, which can reduce the harm of landmine explosion to human bodies.

Background

Although modern wars are mainly confronted by information and high-tech weapons, the victory or defeat of the wars still cannot fight on the ground, so the land mines still play an important role in the wars. A mine is an explosive firearm buried in the ground or laid on the ground, which can be conveniently placed in a large area to prevent enemies from advancing. The killing effect of the land mine is mainly realized through shock waves and fragments generated by explosion, the explosion center can generate pressure of about 1.5 ten thousand Mpa, the damage is mainly traumatic amputation, the amputation rate is as high as 70% -80%, once the land mine is accidently touched, permanent damage is caused slightly, and the life is lost seriously. According to data statistics, the number of underground mines in the world reaches 1.1 hundred million, and the number of casualties caused by mines reaches 26000 every year, so that the research on the battle boots capable of preventing explosion and reducing injuries is particularly important.

The existing mine-proof boots comprise mine boots made of foamed metal aluminum and air cushion type mine-proof boots made of square soft plastics, the size of the existing mine-proof boots is 40 multiplied by 22 multiplied by 15cm, the weight of the existing mine-proof boots is close to 5kg, the pressure on the mine is reduced by increasing the action area, and therefore triggering of the mine is prevented, but the existing mine-proof boots have the defects of large size, heaviness and inconvenient action, are difficult to apply to practical occasions, and cannot meet actual combat requirements.
