[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-3 The embodiment provides an automatic light change welding mask, including welding mask shell 1, welding mask shell 1 is set up on the face frame slot 101, the inside dustproof film 5 of face frame slot 101 is slidably installed, welding mask shell 1 is fixedly installed on the side of face frame slot 101, the inside top and bottom of winding box 6 are rotatably connected with reel 7, one end of dustproof film 5 is inserted into the inside winding box 6 and one end is fixedly connected on the outer ring surface of reel 7, when the automatic light change welding mask is used, through the reel 7 of rotation dustproof film 5 is coiled on reel 7, and when the automatic light change welding mask is not used, the one end of dustproof film 5 is pulled to the inside face frame slot 101 and is away from the one end of winding box 6, at this time, dustproof film 5 shields the inside face of face frame slot 101, thereby effectively preventing the automatic light change welding mask from not being used, and the lens is bumped, rubbed and scratched, and the service life of the lens is improved.

[0026] In the embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the inner top and bottom of the face frame slot 101 are provided with sliding grooves 102, and the two longer edges of the dustproof film 5 are slidingly installed between the two sliding grooves 102. The dustproof film 5 is a transparent plastic sheet, and a rectangular groove matching the size of the dustproof film 5 is formed on one side of the winding box 6 and communicates with one end of the face frame slot 101. One end of the dustproof film 5 passes into the rectangular groove from one end of the face frame slot 101 and enters the inside of the winding box 6. A manual winding wheel 8 is fixedly installed on the top outer ring surface of the winding shaft 7. A slot hole is formed on the top of the outer side of the winding box 6, and part of the manual winding wheel 8 extends to the outside of the winding box 6 through the inside of the slot hole. Thus, when the manual winding wheel 8 is actuated, the winding shaft 7 rotates, and the dustproof film 5 slides in the sliding groove 102 and gradually winds on the outer ring surface of the winding shaft 7.

[0027] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the inner two side surfaces of the face frame slot 101 are embeddedly installed with magnet pieces 3, and the one end edge of the dustproof film 5 is fixedly installed with a push plate 4. The length of the push plate 4 is the same as the distance between the top and bottom of the inner side of the face frame slot 101. Metal pads are embeddedly installed on the two side surfaces of the push plate 4. During the sliding of the dustproof film 5, no matter which end of the dustproof film 5 slides to the inner side of the face frame slot 101, the metal pads on the push plate 4 can be magnetically attracted to the magnet pieces 3 on the inner side of the face frame slot 101, thereby preventing the dustproof film 5 from sliding automatically when shielding the lens.

[0028] Working principle: when the automatic variable light welding mask is used, the winding shaft 7 rotates by manually actuating the manual winding wheel 8, and the dustproof film 5 slides in the sliding groove 102 and gradually winds on the outer ring surface of the winding shaft 7. The one side surface of the push plate 4 is attracted to the magnet piece 3 on the inner side of the face frame slot 101, which does not affect the normal use of the automatic variable light welding mask. When the automatic variable light welding mask is not in use, the dustproof film 5 is unwound from the winding shaft 7 by pulling the dustproof film 5 to the other end of the inner side of the face frame slot 101 through the push plate 4. At this time, the other side surface of the push plate 4 is attracted to the magnet piece 3 on the inner side of the face frame slot 101, and the dustproof film 5 shields the automatic light filter 2 on the inner side of the face frame slot 101, thereby effectively preventing the lens from being scratched and rubbed when the automatic variable light welding mask is not in use, and improving the service life of the lens.

[0029] All the technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
