Problems solved by technology
However, in the production process of the existing safety helmet, the glue cannot completely fill the gap between the shell and the cushioning liner, which makes the combination between the shell and the cushioning liner not tight enough, resulting in a gap between the shell and the cushioning liner. Gap, the gap can not absorb the impact energy, it is easy to cause the wearer to suffer more serious injury due to secondary impact, in order to reduce the injury, the thickness of the buffer lining can only be increased, which leads to the larger size of the existing helmet

Embodiment Construction
[0024] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.
[0025] Such as figure 1 As shown, a safety helmet of the present invention includes a cap shell 1 and a cushioning liner 2 fitted in the cap shell 1, wherein the material of the cushioning liner 2 can be EPS, EPP or EPO.
[0026] Cooperate figure 1 As shown, the key point of the safety helmet of the present invention is: the foam body 3 formed by foaming glue is filled between the cap shell 1 and the buffer lining 2, and the foam glue can be polyurethane For the foam rubber, the thickness of the foam body 3 is preferably 1-5 mm. The safety helmet of the present invention has the advantages that: on the one hand, the foam body 3 is formed by foaming styrofoam, so that the foam body 3 can be firmly combined with the cap shell 1 and the buffer lining 2, and the cap can be eliminated. The gap between the shell 1...

The invention discloses a safety helmet, which comprises a helmet shell and a buffer lining which is matched in the helmet shell, wherein a space between the helmet shell and the buffer lining is filled with a foamed body which is formed by foaming polystyrene foam. According to the safety helmet provided by the invention, by filling the space between the helmet shell and buffer lining with the foamed material (the foamed body) which is formed by foaming the polystyrene foam, a gap between the helmet shell and the buffer lining can be eliminated, so that the safety helmet can effectively relieve impact force and has the advantage of being strong in anti-impact capacity; and the boundary dimensions of the safety helmet can be reduced. The invention also discloses a production method of thesafety helmet.
Description
technical field [0001] The invention relates to the field of safety helmets, in particular to a safety helmet and a production method thereof. Background technique [0002] Existing safety helmets generally include a cap shell and a buffer lining attached to the inner surface of the cap shell. The buffer lining of the existing safety helmet is generally attached to the inner surface of the cap shell by glue, wherein the glue is generally For glass glue. However, in the production process of the existing safety helmet, the glue cannot completely fill the gap between the shell and the cushioning liner, which makes the combination between the shell and the cushioning liner not tight enough, resulting in a gap between the shell and the cushioning liner. Gap, the gap can not absorb the impact energy, it is easy to cause the wearer to suffer more serious injury due to secondary impact, in order to reduce the injury, the thickness of the buffer lining can only be increased, which ...
