Exposure frame capable of representing weather resistance of thin film in different periods

The utility model discloses an exposure frame capable of representing weather resistance of a film in different periods. The exposure frame comprises a frame body, a sample bearing panel and a plurality of covering units, the frame body is provided with an inclined supporting surface, and the sample bearing panel is arranged on the inclined supporting surface; the sample bearing panel is provided with a plurality of sample fixing mechanisms which can fix corresponding samples on the sample bearing panel; the sample bearing panel is provided with a plurality of covering unit fixing mechanisms which can fix the corresponding covering units on the sample bearing panel; each covering unit is separably arranged on one side of the sample bearing panel through a corresponding covering unit fixing mechanism; in different periods, each covering unit can respectively present a covering state or a taking-down state, so that the sample has different shielding in different periods. According to the utility model, weather
