The utility model discloses a novel electric welding goggle lens, which comprises a protection sheet and an optical filter arranged on one side of the protection sheet, and further comprises a fixing frame, the bottom of the protection sheet and the bottom of the optical filter are fixedly connected with insertion blocks, and the bottoms of the insertion blocks are movably inserted into the fixing frame. Through mutual cooperation of the protection sheet, the optical filter, the fixed frame, the insertion block, the pressing frame, a motion groove, a motion block, a connecting rod, a first spring, a track, a clamping plate, a clamping block, a second spring, a protruding block, a pull ring, an extension rope and an installation opening, the fixed frame and the pressing frame can be rapidly separated in the using process; therefore, the protection sheet and the optical filter can be conveniently and quickly replaced, no matter which part is damaged, only accessories need to be independently replaced, the maintenance cost is low, and the use is convenient.

The utility model discloses a special eye protection glasses structure for electric welders, which relates to the technical field of electric welding eye protection and comprises a glasses frame body, photochromic lenses are mounted on the glasses frame body and comprise two groups of parallel glass substrates, and transparent conductive layers are oppositely arranged between the two groups of glass substrates; an ion storage layer is arranged on one group of transparent conducting layers, and an electrochromic layer is arranged on the other group of transparent conducting layers; an ion conductor layer is arranged between the electrochromic layer and the ion storage layer; one end of the fireproof electric control line is connected with the contact button, and the other end of the fireproof electric control line is connected with the electric control board; a battery pack is arranged in the glasses frame body; the two ends of the battery pack are connected to the photochromic glasses through the electric control board, and the contact button is connected through the fireproof electric control line to control opening and closing of the battery pack and the photochromic lenses. The contact button is mounted on the electric welding handle, so that the technical problems that a protective mask needs to be frequently taken and placed during electric welding, and double-hand operation cannot be performed all the time are solved.
