Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The present utility model provides a WenDy bulletproof helmet as shown in FIGS. 1-4, comprising a helmet body 101;

specifically, the edge of the helmet body 101 is provided with a helmet edge sealing ring 102, and the inner walls of the two sides of the helmet body 101 are fixedly connected with fastening belts 103, wherein: the helmet body 101 is formed by sequentially paving and bonding a pe woven fabric layer 104, an ultra-high molecular weight polyethylene fiber layer 105, a Kevlar fiber layer 106, an aramid woven fabric layer 107 and the pe woven fabric layer 104, and the forming mode is specifically hot cutting forming and cold pressing forming.

Specifically, the inner wall of the helmet body 101 is fixedly connected with a plurality of buffer devices 108, the buffer devices 108 specifically comprise adhesive 109, an outer sliding body 201, an inner sliding body 202, a buffer pad 203 and a spring 205, the upper end of the outer sliding body 201 is adhered to the inner wall of the helmet body 101 through the adhesive 109, a chute 204 is arranged in the outer sliding body 201, the inner sliding body 202 is slidably connected in the chute 204, the buffer pad 203 is fixedly connected to the bottom of the inner sliding body 202, the spring 205 is arranged in the chute 204, and two ends of the spring 205 are fixedly connected to the outer sliding body 201 and the inner sliding body 202 respectively.
