This utility model discloses a replaceable protective film structure for a cash register touchscreen, belonging to the technical field of cash register touchscreen protection equipment. It includes a cash register body, with a screen frame mounted on top of the body via a bracket. A touchscreen is embedded within the screen frame. The screen frame has a combination of concave and linear frames along its four perimeter. A non-adhesive protective film is pressed and fixed inside the concave and linear frames, covering the touchscreen area. A threaded post is located at the middle of the front side of the vertical section of the concave frame, and a concave bracket is fitted onto the threaded post, distributed along the inner end of the outer side of the concave frame. This replaceable protective film structure is used to fix a non-adhesive protective film to the touchscreen panel of the cash register. It also facilitates quick replacement when the protective film is heavily soiled, improving replacement efficiency and avoiding the problem of residual adhesive on the touchscreen panel.
