Description

Eye protection glasses

Technical Field

The utility model relates to a protection device of protection eyes under the highlight specifically is a goggles.

Background

In the converter steelmaking of a steel plant, a worker can estimate the temperature of the furnace fire by directly observing the flame condition in the furnace, thereby judging whether the system is normal or not and making corresponding parameter adjustment. The condition of the molten steel smelted in the converter can also be judged whether tapping is near by observing.

The fire and the molten steel are high-temperature and high-light substances, the high temperature and the high light of flame and the molten steel are far larger than the range which can be born by naked eyes, and the direct naked eye watching causes eye pain, blurred vision, central dark spots and great damage to eyes. Therefore, when observing, workers need to wear goggles, which are usually filter lenses made of blue cobalt glass, so as to reduce the irritation of strong light, high heat, ultraviolet light and infrared light. Experienced technicians can observe molten steel through the cobalt blue lenses, estimate the temperature of the molten steel, judge whether the molten steel is close to a tapping value, make tapping preparation in advance when tapping is close to, pay close attention to the prompt of equipment, and avoid missing the optimal tapping time.

The goggles in the smelting workshop in the prior art usually comprise a goggle frame, the goggle frame is connected with a buckle through a bolt and a connecting rod, the buckle is clamped on the brim of the mounting cap, the lenses are fixed through a clamp, the clamp is a C-shaped ring, the mounting bolt is arranged on the opening of the C-shaped ring, and the two ends of the clamp are tightened through the bolt to fix the lenses. The lens is used for turning the lens to the brim of a hat, and the lens is turned to the brim of a hat to avoid shielding sight when the situation of molten steel does not need to be observed. The prior art rear-mounted safety helmet has the following disadvantages: 1. the lens forms an upward protruding structure after being turned out of the brim of the hat, and is often touched to hinder the work of workers, so that the lens is easy to scratch; 2. after being used for many times, the bolt joint is easy to relax; 3. the buckle is easy not hard up, and the goggles often drops.
