Abstract
The invention belongs to the field of electric welding technologies, and particularly relates to an eye protection device. The eye protection device comprises a lens base, baffles, a support and fixing clamps. An eye protection lens and a glass piece are sequentially fixed to the lens base. The two short sides of the lens base are turned upwards to clamp the glass piece and the eye protection lens. The two long edges of the lens base are fixedly connected with the two baffles respectively. The middle of the lens base is hollowed out and turned downwards to form the support. A circular hole is formed in the end, close to the lens base, of the support. The other end of the support is turned to form the upper fixing clamp. The circular hole is connected with one end of a spring, and the other end of the spring is connected with the lower fixing clamp. The lower fixing clamp corresponds to the upper fixing clamp. The lower fixing clamp is movably connected with the upper fixing clamp. The glass piece and the eye protection lens are fixed through the lens base; when the eye protection device is used, the lower fixing clamp is pulled, the lower fixing clamp is arranged in a holder nozzle of an electrode holder in a clamped mode, the lower fixing clamp returns through the spring, the baffles can completely block light rays and sparks generated due to electric welding in the process of clamping the holder nozzle of the electrode holder to conduct welding, and electrode welding workers are protected against injuries.
