Problems solved by technology

[0004] However, the defect of this kind of metal helmet is that when the falling object collides with the metal, it will generate a large noise pulse. When the noise is too loud, the wearer will have adverse reactions such as tinnitus. To prevent penetration, but the cushioning effect is poor, when the impact is too large, it is easy to produce a concussion
At the same time, the metal material is of high quality, which makes the wearer uncomfortable to wear

Embodiment 1

[0044] The safety helmet of this embodiment includes a safety helmet body, a head support is arranged inside the safety helmet body, and a fixing belt is arranged at the bottom of the safety helmet. The safety helmet body includes a shell 1 and an interlayer, and the interlayer is located inside the shell 1 . By changing the structural form of the main body of the helmet including the shell 1 and the interlayer, the original single-layer structure is changed into a double-layer structure, which increases the impact resistance of the helmet, and the helmet is made of hard plastic.

[0045] The interlayer and the shell of the safety helmet can be set in one piece, or can be set as a detachable connection between the two. When it is a detachable connection, a buffer gap is reserved at the connection. Further, a buffer gap is provided in the buffer gap. The cotton layer, on the one hand, increases the cushioning effect, and on the other hand, seals the gaps to prevent dust from ent...

Embodiment 2

[0061] The structure of the safety helmet of this embodiment is basically the same as that of Embodiment 1, and the difference is that each elastic member 9 includes an upper movable head 9-2-1, a lower movable head 9-2-2, a sliding Pipe 9-2-3 and the first spring 9-2-4, upper movable head 9-2-1 and lower movable head 9-2-2 are respectively positioned at the upper and lower ends of the slide pipe 9-2-3. The upper and lower ends of 9-2-3 are provided with constrictions, the middle part of the upper movable head 9-2-1 has an annular step, and the positioning head 9-2-5 is connected to the lower part of the annular step, and the root of the positioning head 9-2-5 is set There is a rubber ring, the upper part of the lower movable head 9-2-2 has a top 9-2-6, and a cylindrical cavity for the positioning head to be inserted is arranged inside the top 9-2-6, and the first spring 9-2-4 is set in the cylindrical cavity.

Embodiment 3

[0064] The structure of the safety helmet of this embodiment is basically the same as that of Embodiment 1, the difference being that: an epp fireproof foam layer 13 is arranged on the lower surface of the inner shell 2, and a sweat-absorbing layer 14 is arranged on the surface of the epp fireproof foam layer 13. The epp fireproof foam layer 13 is located on the inner surface of the inner shell. It has the characteristics of light weight and soft fireproof contact. Contact causes trauma. The sweat-absorbing layer can absorb moisture and sweat to keep the inside of the cap dry.

Abstract

The invention discloses a safety helmet. The safety helmet comprises a safety helmet body, a head support is arranged inside the safety helmet body, a fixing band is arranged on the lower portion of the safety helmet, the safety helmet body comprises a shell (1) and a sandwiched layer, and the sandwiched layer is located in the shell (1) and detachably connected with the shell (1). The safety helmet is of a double-layer structure which forms double-layer guarantees, the anti-impact capacity of the safety helmet can be improved, it can be prevented that after being impacted, the helmet body isprone to brittle rupture and easily loses safety, and the safety helmet can adapt to field operation, special operation, down-hole operation and other environments, and safely protects the head of a human body.

Description

technical field [0001] The invention relates to the field of safety products, in particular to a safety helmet and safety helmet production equipment Background technique [0002] As the name suggests, safety helmets are used for safety protection, and are mostly used in construction sites and other scenes to prevent falling objects. Most of the existing safety helmets are integrally formed by a single-layer plastic shell. The impact capacity is limited. In special scenarios, such as underground operations, field operations, severe weather, hail weather, etc., plastic safety helmets are easily brittle and cracked after impact, thus losing their safety protection. Later, a new product was developed to solve this problem. metal cap. [0003] Chinese patent application number: 200610076843.5 discloses a safety helmet, which includes a cap shell and a cap liner, and the cap shell is formed by stamping a metal plate. The metal lining can effectively prevent sharp objects droppe...
