Magnesium alloy safety helmet with compression-resistant and anti-deformation structure and use method of magnesium alloy safety helmet

Abstract

The magnesium alloy safety helmet comprises a helmet body, the brim of the helmet body is arranged on one side, a telescopic groove is formed in the lower end of the brim of the helmet body, limiting grooves are formed in the inner walls of the front side and the rear side of the telescopic groove, a shading mechanism is installed in the telescopic groove, and a fixing lining matched with the helmet body in size is arranged in the helmet body. The safety helmet has the beneficial effects that the safety helmet is mainly composed of the helmet body and the fixed lining, the multiple compression-resistant rods are arranged between the helmet body and the fixed lining, it can be guaranteed that when the helmet body is impacted, large-area sunken deformation occurs, and the safety helmet is not prone to damage. Meanwhile, the heat insulation function can be achieved; and the fixed pipe with the fan is mounted in the fixed lining, so that hot air in the fixed lining can be quickly exhausted through the fan during use, the temperature in the fixed lining is reduced, and the situation that normal work is affected due to the fact that workers feel uncomfortable is avoided.

Description

technical field [0001] The invention relates to a magnesium alloy safety helmet and a using method thereof, in particular to a magnesium alloy safety helmet with a compression-resistant and anti-deformation structure and a using method thereof, belonging to the technical field of safety helmets. Background technique [0002] Magnesium alloy safety helmet is a kind of safety helmet, which can protect the head of the staff, and every staff who enters the construction site must wear it. [0003] Most of the magnesium alloy safety helmets currently used are of integral structure. When a heavy object hits the magnesium alloy safety helmet, it is easy to cause a large area of ​​depression and deformation of the cap body of the magnesium alloy safety helmet, which affects the normal wearing of the staff, and the safety is low. When wearing the helmet, due to the poor air mobility of the helmet, a large amount of hot air stays inside the helmet, and the staff may feel uncomfortable ...

AI Technical Summary

Problems solved by technology

[0003] Most of the magnesium alloy safety helmets currently used are integral structures. When heavy objects hit the magnesium alloy safety helmet, it is easy to cause large-area depression and deformation of the magnesium alloy safety helmet, which affects the normal wearing of the staff, and the safety is low. When wearing the helmet, due to the poor air flow of the helmet, a large amount of hot air stays inside the helmet, and the staff will feel uncomfortable after wearing it for a long time, which will affect the normal work; while the brim of the helmet is mostly fixed, and the length is mostly Shorter, the shading effect is poor, and the staff is still prone to glare when walking in a strong light environment; the size of the headband of the safety helmet is fixed, so that it is necessary to manufacture safety helmets of different sizes. If the body is damaged, a new helmet needs to be replaced. If there is no helmet of the same size, the normal work will be affected when the staff wears a helmet of other sizes.
