Description

Technical Field

[0001] The utility model relates to the technical field of bulletproof helmets, in particular to a detachable light bulletproof helmet. Background Technique

[0002] A bulletproof helmet is a single-person protective device used to protect the head from injury, and is an essential personal protective equipment for military, police and other security personnel when facing bullet threats and other environments during mission execution. It can absorb and dissipate the kinetic energy of the bullet, prevent penetration, and effectively protect the head. At present, the main materials for making bulletproof helmets are ultra-high molecular weight polyethylene fiber and aromatic polyamide. The helmet made of ultra-high molecular weight polyethylene fiber is lighter.

[0003] Most of the current bulletproof helmets are integrally formed, resulting in a single application scenario for the helmet. When performing some particularly dangerous tasks, ordinary bulletproof helmets cannot effectively prevent high-penetration bullets from causing harm to the human head. At this time, it is necessary to wear a bulletproof helmet made of high-strength aluminum alloy or fiberglass. Although high-strength aluminum alloy or fiberglass has good bulletproof effect, it is relatively heavy, and wearing it during non-mission periods will seriously consume the physical strength of the user. Therefore, a detachable light bulletproof helmet is proposed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a detachable light bulletproof helmet to solve the problems mentioned in the above background technique.

Slots 19 adapted to the connecting blocks 4 are provided at the positions of the bulletproof helmet body 1 corresponding to the connecting seats 3. A left - right screw rod 5 is rotatably connected to the inner surface of the connecting seat 3. The left - right screw rod 5 rotatably penetrates through the outer surface of the rear side of the connecting seat 3. A knob 8 is fixedly connected to the outer surface of the rear side of the left - right screw rod 5. Two threaded plates 6 are threadedly connected to the outer surface of the left - right screw rod 5. Limiting blocks 7 are fixedly connected to the outer surfaces of the two threaded plates 6. Two limiting grooves adapted to the limiting blocks 7 are provided on the outer surface of the connecting block 4. Specifically, when it is necessary to equip the bulletproof fiberglass layer 2 for special tasks, insert the connecting block 4 from the bottom of the bulletproof helmet body 1 into the slot 19 from top to bottom. Rotate the knob 8, and the knob 8 drives the left - right screw rod 5 to rotate. When the left - right screw rod 5 rotates, it drives the threaded plate 6 to move, so that the threaded plate 6 drives the two limiting blocks 7 to move towards each other until the limiting blocks 7 are inserted into the limiting grooves to limit the connecting block 4, thereby installing the bulletproof fiberglass layer 2. When it is necessary to disassemble the bulletproof fiberglass layer 2, rotate the knob 8 in the reverse direction to make the limiting blocks 7 disengage from the limiting grooves and release the limit on the connecting block 4, thus realizing a detachable and split - type setting. During wearing during non - special tasks, the overall mass is lighter, reducing the physical consumption of the wearer.

[0023] In this embodiment, a first inner liner 9 is provided inside the bulletproof fiberglass layer 2. A first hook surface 10 is fixedly connected to the outer surface of the bulletproof fiberglass layer 2 facing the first inner liner 9, and a first loop surface 11 is fixedly connected to the outer surface of the first inner liner 9 facing the bulletproof fiberglass layer. Specifically, when wearing the bulletproof fiberglass layer 2, the comfort of wearing is increased through the first inner liner 9, and it can effectively protect the human head. And when it is necessary to replace the first inner liner, the first loop surface 11 is removed from the first hook surface 10, and the first inner liner 9 is replaced.

[0024] In this embodiment, a second inner liner 12 is provided inside the bulletproof helmet body 1. A second hook surface 13 is fixedly connected to the outer surface of the bulletproof helmet body 1 facing the second inner liner 12, and a second loop surface 14 is fixedly connected to the outer surface of the second inner liner 12 facing the bulletproof helmet body 1.

[0027] In this embodiment, wearing strips 18 are provided on the outer surfaces of the left and right sides of the bulletproof helmet body 1. Specifically, the wearer wears the bulletproof helmet body 1 on the head through the wearing strips 18.

[0028] In this embodiment, the outer shell of the bulletproof helmet body 1 is made of high molecular polyethylene fiber material. Specifically, the high molecular polyethylene fiber material has an extremely high strength ratio and an extremely low fiber density. At the same time, it has a low elongation at break and a large work of fracture, and has a strong energy absorption capacity, so it has outstanding impact resistance and cut resistance.

[0029] Working principle: When in use, the wearer wears the bulletproof helmet body 1 on the head through the wearing strip 18, and can adjust the face mask 16 as needed to protect the face. The sight of the wearer is not affected through the observation mirror 17. When it is necessary to equip the bulletproof fiberglass layer 2 for special tasks, the connecting block 4 is inserted into the slot 19 from the bottom of the bulletproof helmet body 1 from top to bottom. Rotate the knob 8, and the knob 8 drives the positive and negative lead screw 5 to rotate. When the positive and negative lead screw 5 rotates, it drives the threaded plate 6 to move, so that the threaded plate 6 drives the two limit blocks 7 to move towards each other until the limit blocks 7 are inserted into the limit slots to limit the connecting block 4, thereby installing the bulletproof fiberglass layer 2. When it is necessary to disassemble the bulletproof fiberglass layer 2, rotate the knob 8 in the reverse direction to make the limit block 7 disengage from the limit slot and release the limit on the connecting block 4, so as to achieve a detachable and split design. During non-special tasks, the overall weight is lighter when worn, reducing the physical consumption of the wearer.

[0030] When the user wears this helmet, the comfort of wearing is increased through the second inner liner 12, and it can effectively protect the human head. And when it is necessary to replace the second inner liner, the second hook surface 14 of the magic tape is removed from the second loop surface 13 of the magic tape to replace the second inner liner 12.
