Description

Police protective helmet Technical Field The invention relates to the technical field of police helmets, in particular to a police protective helmet. Background In police operations, police personnel often need to be faced with a variety of complex and dangerous environments and situations, such as performing patrol tasks, handling emergency events, participating in capture actions, and the like. In these working scenarios, police officers need to protect their heads from accidental impact, falling objects and other injuries, and also need to deal with the problem of visual interference caused by different weather conditions and special task requirements. The traditional police helmet has relatively single function, mainly focuses on basic head protection, and has less functional consideration on visual aspects. For example, under strong light environment, strong sunlight can direct the eyes of police officers, influence the sight, reduce the working efficiency and even possibly cause potential safety hazards, and in rainy days, rainwater can directly strike the face to block the sight, and great inconvenience is brought to the actions of the police officers. Furthermore, conventional helmets do not provide effective ballistic protection to the eyes of police personnel when performing some special tasks, such as facing a scene where a gun strike threat may exist. Although some helmets with partial functions exist in the market at present, the helmets often have a plurality of defects. The helmet with the rainproof function has the advantages that the design of the rainproof face shield is not reasonable enough, the drainage effect is poor, rainwater is easy to accumulate on the face shield, and the sight is influenced. Therefore, a police protective helmet is provided at present for solving the problem that the sight is affected when the existing protective helmet is inconvenient to replace lenses and rains.
