Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric power inspection, specifically to the electric power inspection safety helmet. BACKGROUND

[0002] The safety helmet is a cap that protects the head from falling objects and other specific factors. It is composed of a helmet shell, a helmet liner, a chin strap, and accessories. During electric power inspection, an insulating safety helmet is needed. The insulating safety helmet is made of insulating material and has a neck strap and a movable headband. It is used to prevent electric shock during live-line work. Like other protective safety tools, the use of these protective devices inevitably restricts human operation. Although the safety helmet is small, it plays a significant role in critical situations by protecting workers from accidents and reducing the risk of injury.

[0003] The safety helmet for electric power inspection disclosed in the Chinese utility model patent application publication CN214594469U has a main gear, a driven gear, a safety helmet shell, and a lighting lamp. The gear rotation changes the illumination angle of the lighting lamp. The gear engagement connection method also reinforces the adjusted lighting angle, effectively solving the problem of fixed illumination angle of the lighting lamp, expanding the application range of the lighting lamp, providing different lighting conditions for electric power maintenance of inspection personnel, and improving the efficiency of electric power maintenance of inspection personnel. However, the transmission rod drives the main gear to rotate, and then the lighting lamp rotates, which not only has poor convenience but also has a complex structure, increasing the overall weight of the safety helmet. The existing safety helmet has poor ventilation, and long-term wearing can cause sweating. The composition of sweat mainly includes electrolytes such as sodium, potassium, and chlorine. These electrolytes make sweat have certain conductivity. When sweat accumulates in the safety helmet or comes into contact with other conductive materials, it may form an electric path, increasing the risk of electric shock, and has the disadvantage of poor use effect. At the same time, in order to make the inner lining of the safety helmet more fit the head, the adjustment belt of the inner lining is adjusted, usually adopting a buckle structure design. This structure not only easily causes the adjustment belt to loosen, but also needs to be adjusted according to the buckle hole position during adjustment, which cannot achieve precise adjustment and easily causes the inner lining to be not fit, which may not effectively transmit force when impact occurs, and has the disadvantage of poor practicality.
