Technical Field

[0001] The utility model belongs to the technical field of non-metallic bulletproof helmets, and in particular to a fully protective bulletproof helmet with quick disassembly and assembly. Background Technique

[0002] With the flexible and changeable combat scenarios in modern warfare, in addition to having the comprehensive protection ability of the head and face, the fully protective bulletproof helmet also needs to have the function of quickly switching under different combat states.

[0003] For the existing fully protective bulletproof helmets, their connection methods are cumbersome, and they do not have the function of quickly disassembling and assembling the eye protection component and the jaw protection component. Special tools are needed to achieve disassembly, assembly and combination, which is time-consuming and laborious, and affects the actual use effect of the protective helmet.

[0004] In addition, the installation positions of the eye protection component and the jaw protection component of the existing fully protective bulletproof helmets are not scientifically set, and most of them are concentrated at the front end of the bulletproof helmet component, resulting in the center of gravity of the fully protective bulletproof helmet being too far forward, and it is easy to cause neck discomfort to the user after wearing for a long time.
