Problems solved by technology

[0003] The inventors found that the existing safety helmets have simple structural design and single function, and most of the shock absorbers in the caps use ordinary support structures or shock absorbing cushions for shock absorption, and the shock absorption effect is slightly poor, and the impact resistance performance is relatively low. Single, poor protection performance, thus affecting its safety performance

Embodiment 1

[0042] refer to figure 1 , figure 2 , image 3 and Figure 8 , a safety helmet, comprising a cap body 1, a cap liner 2 and a cap band 3, the top of the cap body 1 is connected with a horizontally placed arc-shaped reinforcing plate 4, and the two ends of the arc-shaped reinforcing plate 4 are movably connected with mounting blocks 5, An arc-shaped elastic piece 6 is connected between the mounting blocks 5, and the arc-shaped elastic piece 6 is located directly above the arc-shaped reinforcing plate 4. The two ends of the elastic sheet 6 squeeze the mounting block 5 to disperse the impact force, which solves the problem of single cushioning performance of the cap liner in the prior art and improves the protection effect.

Embodiment 2

[0044] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 6 and Figure 8, a safety helmet, which is basically the same as that of Embodiment 1, furthermore, a chute 7 is opened on the side of the arc-shaped reinforcing plate 4 away from the cap body 1, and two symmetrically distributed sliders are slidably connected in the chute 7 8. The opposite side of the slider 8 is movably connected with a support plate 9, and the side of the two support plates 9 away from the slider 8 is hinged through a hinge, and the hinge is connected to the middle of the arc-shaped elastic sheet 6, and the two sliders 8 are connected to each other. A buffer rubber plate 10 is connected between the far side and the groove wall of the chute 7. When an object hits the cap body 1 of the safety helmet, the arc-shaped elastic sheet 6 is squeezed, and the arc-shaped elastic sheet 6 transmits the pressure to the support plate 9. The support plate 9 drives the slider 8 to slide in the chute ...

Embodiment 3

[0046] refer to figure 1 , figure 2 , image 3 and Figure 8 , a safety helmet, which is basically the same as that of Embodiment 1, furthermore, the bottom of the installation block 5 is connected with a triangular rubber block 11, and the triangular rubber block 11 is offset against the cap body 1, when an object hits the cap body 1 of the safety helmet , Extrude the arc-shaped elastic sheet 6, and the two ends of the arc-shaped elastic sheet 6 extrude the mounting block 5, so that the triangular rubber block 11 is offset against the cap body 1, and the cushioning performance is improved.

Abstract

The invention discloses a safety helmet, belonging to the technical field of safety protection equipment. The safety helmet comprises a helmet body, a helmet lining and a helmet strap, wherein the topof the helmet body is connected with a transversely placed arc-shaped reinforcing plate; two ends of the arc-shaped reinforcing plate are movably connected with mounting blocks; and an arc-shaped elastic piece is arranged between and connected with the mounting blocks and located right above the arc-shaped reinforcing plate. According to the safety helmet, when an object impacts the body of the safety helmet, the arc-shaped elastic piece is extruded, and the two ends of the arc-shaped elastic piece extrude the mounting blocks to disperse impact force, so the problem that the buffering performance of a helmet lining is single in the prior art is solved, and protection effect is improved. The invention further discloses a production process of the safety helmet. The safety helmet produced and manufactured through the process has the advantages of firm structure and high buffering capacity.

Description

technical field [0001] The invention relates to the technical field of safety protection equipment, in particular to a safety helmet and its production. Background technique [0002] The safety helmet is a round hat made of steel or similar materials worn to protect the top of the head, and it is a protective product to prevent alluvium from injuring the head. It consists of a hat shell, a hat lining, a hat strap and a back hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. Impact suction performance, puncture resistance performance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helmets. [0003] The invent...
