Description

Technical Field

[0001] The present invention belongs to an explosion-proof boot, and more particularly relates to an impact-resistant explosion-proof boot. Background Art

[0002] After a landmine explodes in the soil, a strong shock wave is generated in the soil. Due to the certain porosity of the soil, the strong action of the shock wave compacts and crushes the soil around the landmine. More than half of the energy of the shock wave is quickly consumed and attenuated into a stress wave. When the stress wave reaches the interface between the soil and the foam at the bottom of the mine-protecting boot, reflection and transmission will occur. The compression wave, the reflected wave, and the subsequent gas expansion cause the soil above the charge to loosen, peel off, and be thrown, thus forming an inverted conical crater. The bottom of the explosion-proof boot worn during mine sweeping will be continuously impacted by the transmitted wave and a part of the explosion gas products. The impact-resistant layer at the bottom of the explosion-proof boot in the prior art is generally made of a high-hardness material or a composite of multiple materials to ensure the strength of the impact-resistant layer. During mine clearance, the bottom of the shoe is blocked from the high-temperature impact from the bottom up by the impact-resistant layer. However, the above-mentioned impact-resistant layer is difficult to buffer the high-temperature impact while blocking the high-temperature impact, so the protection performance needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an impact-resistant explosion-proof boot with good protection performance.

[0004] The content of the present invention includes a boot bottom and a boot surface. The boot bottom includes a grounding layer and an impact-resistant layer I arranged in sequence. The impact-resistant layer I includes a guard plate and a protective member. The protective member is provided with folds. The protective member covers the side of the guard plate facing away from the grounding layer. The side of the protective member is wrapped around the side of the guard plate facing the grounding layer and is fixedly connected to the guard plate. There is an air vent between the side of the protective member and the guard plate. When the impact-resistant layer I is subjected to a high-temperature impact from the bottom up, the air wave enters between the guard plate and the protective member along the air vent, causing the folds of the protective member to expand.

[0005] Further, the folds are located on the side of the guard plate facing away from the grounding layer, and the folds protrude in the direction away from the grounding layer.

[0006] Further, the folds are encapsulated on the guard plate by a colloid.

[0007] Further, the material of the protective member is a carbon fiber composite material.

[0008] Furthermore, the protective member includes a first protective layer and a second protective layer, both of which are provided with wrinkles. The first protective layer covers the side of the guard plate facing away from the grounding layer, and the side edge of the first protective layer is wrapped around the side of the guard plate facing the grounding layer and is fixedly connected to the guard plate. There is an air vent left between the first protective layer and the guard plate. The second protective layer covers the side of the first protective layer facing away from the grounding layer, and the side edge of the second protective layer is wrapped around the side facing the grounding layer and is fixedly connected to the guard plate. There is an air vent left between the second protective layer and the first protective layer and / or between the second protective layer and the guard plate.

[0009] Furthermore, the guard plate includes a forefoot guard plate and a heel guard plate. There are two first protective layers, and the side edges of the two first protective layers are respectively bent and wrapped around the side edges of the forefoot guard plate and the heel guard plate. The second protective layer is wrapped around the two first protective layers.

[0010] Furthermore, it further includes a second anti-impact layer, which is arranged on the side of the first anti-impact layer facing away from the grounding layer. The second anti-impact layer includes an elastoplastic grid layer, and the elastoplastic grid layer includes a number of grid monomers connected in sequence.

[0011] Furthermore, the diameter of the inscribed sphere that can be accommodated in a single grid monomer is less than or equal to 1 mm.

[0012] Furthermore, it further includes a lining layer, which is arranged on the side of the second anti-impact layer facing away from the grounding layer.

[0013] Furthermore, a protective toe cap is provided on the toe part of the boot surface.

[0014] The beneficial effect of the present invention is that by arranging a protective member with wrinkles on the guard plate, when the first anti-impact layer is subjected to an explosion high-temperature impact from bottom to top, the wrinkles are opened by the air wave, so that the protective member forms a bulging sac-like structure to buffer the high-temperature impact, thereby reducing the damage to the soft tissues and bones of the human foot and improving the protective performance of the explosion-proof boots.

Detailed implementation manner

[0019] As shown in the Figures 1-3 accompanying drawings, the present invention includes a sole 1 and an upper 2. Preferably, the material of the upper 2 is a fireproof and water-resistant material; the sole 1 includes a grounding layer 11 and a first impact-resistant layer 12 arranged in sequence. Preferably, the material of the grounding layer 11 is rubber; the first impact-resistant layer 12 includes a guard plate 122 and a protective member 121. The protective member 121 is provided with folds. The protective member 121 covers the surface of the guard plate 122. Specifically, the protective member 121 covers the side of the guard plate 122 facing away from the grounding layer 11. The side of the protective member 121 is bent. The bent side of the protective member 121 covers the side of the guard plate 122 facing the grounding layer 11. And the side of the protective member 121 is fixedly connected to the guard plate 122. There is an air vent between the side of the protective member 121 and the guard plate 122. That is, when the side of the protective member 121 covers the guard plate 122, the side of the protective member 121 and the guard plate 122 are not completely closed, so that air can flow along the space between the protective member 121 and the guard plate 122. When the first impact-resistant layer 12 is subjected to a high-temperature impact from bottom to top, the air wave enters between the guard plate 122 and the protective member 121 along the air vent, causing the folds of the protective member 121 to expand.

[0020] For the anti-impact explosion-proof boots provided by the present invention, by providing a protective member 121 with folds on the guard plate 122, when the first impact-resistant layer 12 is subjected to an explosion high-temperature impact from bottom to top, the air wave can enter between the guard plate 122 and the protective member 121 along the air vent, causing the folds on the protective member 121 to expand, so that the protective member 121 forms a bulging sac-like structure. During this process, the high-temperature impact can be buffered, thereby reducing the damage to the soft tissues and bones of the human foot and improving the protective performance of the explosion-proof boots.

[0021] In the present invention, the folds are located on the side of the guard plate 122 facing away from the grounding layer 11. The part of the protective member 121 provided with folds is located on the upper surface of the guard plate 122, and the folds protrude in the direction away from the grounding layer 11. That is, the protruding direction of the folds is the same as the direction of the high-temperature impact. When the first impact-resistant layer 12 is subjected to a high-temperature impact from bottom to top, the folds are propped up faster, effectively ensuring the buffering effect on the high-temperature impact.

[0022] In the present invention, the wrinkles are encapsulated on the guard plate 122 by a colloid, which can facilitate the fixation of the protection member 121. And when the air wave enters between the guard plate 122 and the protection member 121 along the air inlet, the colloid melts due to high temperature, and it will not affect the opening of the wrinkles.

[0023] In the present invention, the material of the protection member 121 is a carbon fiber composite material, which has high strength, good heat resistance and impact resistance.

[0024] In the present invention, the protection member 121 includes a first protection layer 1211 and a second protection layer 1212. Wrinkles are provided on both the first protection layer 1211 and the second protection layer 1212. The first protection layer 1211 covers the side of the guard plate 122 facing away from the grounding layer 11. The side edge of the first protection layer 1211 is wrapped around the side of the guard plate 122 facing the grounding layer 11 and is fixedly connected to the guard plate 122. An air inlet is left between the first protection layer 1211 and the guard plate 122. The second protection layer 1212 covers the side of the first protection layer 1211 facing away from the grounding layer 11. The side edge of the second protection layer 1212 is wrapped around the side facing the grounding layer 11 and is fixedly connected to the guard plate 122. An air inlet is left between the second protection layer 1212 and the first protection layer 1211 and / or between the second protection layer 1212 and the guard plate 122; preferably, the first protection layer 1211 and the second protection layer 1212 are fixed to the guard plate 122 by rivets, and the rivets are welded to the guard plate 122. By providing the first protection layer 1211 and the second protection layer 1212, the buffering effect on the air wave is better.

[0025] In the present invention, the guard plate 122 includes a forefoot guard plate 1221 and a heel guard plate 1222. There are two pieces of the first protection layer 1211. The side edges of the two pieces of the first protection layer 1211 are bent and wrapped around the side edges of the forefoot guard plate 1221 and the heel guard plate 1222 respectively. Air inlets are left on both pieces of the first protection layer 1211. The second protection layer 1212 is wrapped around the two pieces of the first protection layer 1211. When the first impact-resistant layer 12 is subjected to a high-temperature impact from bottom to top, the air wave enters between the first protection layer 1211 and the forefoot guard plate 1221, between the first protection layer 1211 and the heel guard plate 1222, and between the first protection layer 1211 and the second protection layer 1212 along the air inlets, and can shunt and buffer the air wave, and the buffering effect is better.

[0026] The present invention further includes a second impact-resistant layer 13, which is disposed on the side of the first impact-resistant layer 12 facing away from the grounding layer 11. The second impact-resistant layer 13 includes an elastoplastic grid layer, and the elastoplastic grid layer has a three-dimensional interpenetrating network structure. The elastoplastic grid layer includes a number of grid monomers 131 connected in sequence. By providing the second impact-resistant layer 13, when subjected to a high-temperature impact from bottom to top, the grid monomers 131 can effectively absorb the impact energy, slow down the impact force, further reduce the damage of the explosion blast wave to the soft tissues and bones of the human foot, and further improve the protection performance of the explosion-proof boots.

[0027] In the present invention, preferably, the material of the elastoplastic grid layer is an elastoplastic material, and the elastoplastic grid layer is formed by 3D printing; preferably, the diameter of the inscribed sphere that can be accommodated in a single grid monomer 131 is less than or equal to 1 mm, and preferably, a single grid monomer 131 includes at least two spatial polygon structures, and the edges of the spatial polygon are curves or straight lines.

[0028] Among them, the second impact-resistant layer 13 further includes a third protective layer; in one embodiment, the third protective layer is covered by a whole elastoplastic grid layer; in another embodiment, there are two elastoplastic grid layers, and the thickness of a single elastoplastic grid layer is greater than or equal to 8 mm. The two elastoplastic grid layers respectively cover the side of the third protective layer facing the grounding layer 11 and the side of the third protective layer facing away from the grounding layer 11.

[0029] The present invention further includes a lining layer 14, which is disposed on the side of the second impact-resistant layer 13 facing away from the grounding layer 11. Preferably, the lining layer 14 has 6 to 8 layers of aramid woven fabric.

[0030] In the present invention, a protective toe cap 21 is provided on the toe part of the boot surface 2. The protective toe cap 21 is heat-melted and disposed on the boot surface 2, and the protective toe cap 21 serves to protect the toes.
