Description

Technical Field

[0001] The utility model relates to the technical field of bulletproof helmets, in particular to a lightweight bulletproof helmet with high protection function. Background Art

[0002] A bulletproof helmet is a type of head protection that can be used to resist bullets or stray bullets and is widely used in the military and special police forces.

[0003] According to existing technology, bulletproof helmets can resist some bullets by changing the trajectory of the bullets, so that the bullets cannot observe the helmets. However, the impact force brought by the bullets will still act on the helmets. The impact force will cause the wearer's head to swing. If the swing amplitude is too large or the speed is too fast, it will cause damage to the neck. If the neck is injured, the wearer will not be able to turn the neck flexibly, which will have a fatal impact on the combat process. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] A lightweight bulletproof helmet with high protection function provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, the utility model provides a lightweight bulletproof helmet with high protection function, including a shell 1, one end of the shell 1 is rotatably connected to a protection box 2, the protection box 2 is provided with an inner cavity, the inner wall of the protection box 2 is fixedly connected to a fixed block 3, the top of the fixed block 3 is U-shaped, the side wall of the fixed block 3 is fixedly connected to a first spring 4, one end of the first spring 4 is fixedly connected to a moving block 5, one side of the moving block 5 is rotatably connected to a rotating rod 6, one end of the rotating rod 6 is rotatably connected to a fixing ring 7, the outer wall of the fixing ring 7 is symmetrically fixedly connected to a sliding rod 8, one end of the sliding rod 8 is slidably connected to a track 9, one side of the rotating rod 6 is fixedly connected to a limiting rod 10, one end of the limiting rod 10 is slidably connected to a winding roller 12, the inner wall of the winding roller 12 is provided with a limiting groove 11, one end of the limiting rod 10 is slidably connected in the limiting groove 11, the surface of the winding roller 12 is fixedly connected to a connecting belt 21 in a winding state, and one side of the fixed block 3 is fixedly connected to a fixing groove 13;

[0024] The shell 1 is provided with an inner cavity, and a support rod 27 is fixedly connected to the inner wall of the shell 1. Two fluid layers 26 are fixedly connected to the inner wall of the shell 1. The fluid layer 26 is used to change the trajectory of the bullet through the flow of fluid after the bullet penetrates the shell 1, and at the same time weaken the potential energy of the bullet's movement, thereby playing a protective role. The counterweight bead 25 is used to use the recoil force when the head is tilted back to allow the helmet to generate a forward pulling force, thereby forming a counteracting force with the backward force, thereby playing a protective role. A rolling rod 23 is fixedly connected to the inner wall of the shell 1, and a sliding bar 24 is fixedly connected to one end of the rolling rod 23, and a counterweight bead 25 is slidably connected to one end of the sliding bar 24 in a through-shaped manner. A slide rail 29 is fixedly connected to the inner wall of the shell 1, and a sliding block 28 is slidably connected to one end of the slide rail 29 in a through-shaped manner. A sponge pad 22 is fixedly connected to the bottom of the protection box 2.

[0025] In the first embodiment, when a bullet or a stray bullet hits the helmet, the impact force borne by the helmet will act on the head worn thereon, thereby causing the head to swing. When the helmet swings, the shell 1 will drive the connecting belt 21 to move. Due to the excessive pulling force, the pulling force of the connecting belt 21 will act on the winding roller 12, and the winding roller 12 will be driven to move. During the displacement, the limiting groove 11 and the limiting rod 10 will cooperate, so that the winding roller 12 stops rotating, and then the connecting belt 21 cannot move normally, thereby playing a braking role, weakening or even stopping the trend of head swinging, thereby protecting the neck and avoiding neck strain caused by excessive head swinging. At the same time, when the side of the helmet is hit, the sliding block 28 is allowed to retreat during the horizontal swing, thereby playing a counteracting role.

[0026] One end of the connecting belt 21 is slidably connected to a supporting mechanism, and the supporting mechanism includes an auxiliary wheel 14, a rotating shaft 15 is fixedly connected to the center position of the auxiliary wheel 14, one end of the rotating shaft 15 is fixedly connected to a driven gear 16, and the bottom of the driven gear 16 is meshingly connected to a moving rack 17, one end of the moving rack 17 is fixedly connected to a second spring 18, one end of the second spring 18 is fixedly connected to the inner wall of the protection box 2, one end of the moving rack 17 is fixedly connected to a supporting pad 19, one end of the supporting pad 19 is fixedly connected to a rotating shaft 20 in a through shape, and the rotating shaft 20 is rotatably connected to the inner wall of the protection box 2.

[0027] In the second embodiment, when the connecting belt 21 drives the auxiliary wheel 14 to rotate, the auxiliary wheel 14 will drive the driven gear 16 on the rotating shaft 15 to engage with the movable rack 17, thereby driving the movable rack 17 to move. When the movable rack 17 moves, it can push the support pad 19 to tilt, thereby supporting the neck position, thereby assisting the first embodiment to protect the neck.

[0028] The working principle and use process of the utility model are as follows: when the helmet is hit, the impact force will drive the head to swing, and when swinging, the shell 1 will drive the connecting belt 21 to move, and the connecting belt 21 will pull the winding roller 12 to displace during the rapid movement, so that the limiting groove 11 is connected to the limiting rod 10, so that the winding roller 12 stops rotating. After stopping rotating, the connecting belt 21 can no longer extend out, thereby playing a braking role. When the connecting belt 21 moves, it can drive the auxiliary wheel 14 to rotate. When the auxiliary wheel 14 rotates through the rotating shaft 15, it can drive the driven gear 16 to engage with the moving rack 17, so that the moving rack 17 moves to push the support pad 19 to tilt and support the wearer's neck.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
