The helmet refers to a hat that plays a protective effect on the damage caused by falling objects and other specific factors.The helmet is composed of the hat shell, hat lining, beam, and attachment.
Host composition structure
The helmet is composed of three parts such as hat shell, hat lining.
(1) Hat shell: This is the main component of the helmet. Generally, an oval or hemispherical thin shell structure is adopted.This structure will cause a certain pressure deformation under impact pressure. Due to the rigid performance absorption and decentralization of the material, the surface smooth and round curve can easily slip the impact and reduce the time of impact.According to needs and strengthening the intensity of the hooded hood, the shell can be made into a variety of types such as light top, ceiling, edge, and non -edge.
(2) Hat lining: The hat lining is the general name of the contact part of the head of the wearers head in the hat shell. It consists of a cap hoeb belt, top band, protective belt, support belt, sweat absorption belt, pad tie rope and so on.The material of the hat lining can be made of cotton webbing, synthetic fiber belt and plastic lining belt. The hat holes are ring -shaped bands. When wearing, it is tightly surrounded by human heads.EssenceThe caps of the hat hoop can be divided into two types: fixed band and adjustable band. The hat holes have two types: rear hoe and no rear neck hoop.The top band is a lining strap that is in contact with the top of the head. The top band and the hat shell can be connected with rivets, or the socket with a belt is connected to the socket with the hat shell. The top has a cross shape and six shapes.Correspondingly set 4 to 6.
(3) The lower band: The band tied to the bottom of the bottom, the role of a fixed helmet, the lower band consists of the belt and the lock card.With the hats of the hind -neck hoop, the "y" shape is used.
Introduction
Choose a suitable qualified helmet, and it should be used correctly to play the function of the helmet to ensure the safety of users.The following principles should be paid to the use of a helmet:
(1) Before wearing, check whether the accessories of the helmet are damaged, whether the assembly is firm, whether the hat -lining adjustment part is stuck, whether the socket is reliable, whether the rope is tightly tied, etc.Between 25 and 50mm, the top rope is used to adjust to the specified range.It is convinced that each component can be used after the components are intact.
(2) According to the size of the users head, adjust the length of the hat hoop to the appropriate position (tightly). The helmet worn by the high -altitude operators should have the lower belt and the rear neck hoop and it should be tied to prevent the hat from falling and falling off and.Take it off.
(3) After the hard hat is greatly impacted during use, whether it is found that the hat shell is obviously broken or deformed, it should be stopped and replaced the damaged helmet.Generally, the use period of the helmet does not exceed 3 years.
(4) The helmet should not be stored in places with acid and alkali, high temperature (above 50 ° C), sunlight, humidity, etc. to avoid squeezing heavy objects or spikes.
(5) The hat shell and hat can be washed with cold water and warm water (below 50 ° C). Do not bake it on the heating film to prevent the hat shell from deforming.
