[0025] In the specific implementation process, as Figures 1-5As shown in the figure, a detection device for the weather resistance of an aqueous polyurethane topcoat includes a bottom plate 1. A fixed frame 2 is fixedly arranged at the top end of the bottom plate 1. A placement plate 3 is fixedly arranged inside the fixed frame 2. A power mechanism is movably arranged inside the placement plate 3. Limiting mechanisms are respectively fixedly arranged on both sides of the power assembly. A detection mechanism is fixedly arranged inside the fixed frame 2. The limiting mechanism includes two fixed blocks 4. Connecting columns 5 are respectively fixedly arranged at the bottom parts of the two fixed blocks 4. Locking pieces 6 are respectively fixedly arranged at the bottom parts of the two connecting columns 5. Two moving grooves 7 are opened on one side of the fixed frame 2. One side of each of the two fixed blocks 4 extends into the two moving grooves 7 respectively. The outer surfaces of the two fixed blocks 4 are respectively movably connected with the inner surfaces of the two moving grooves 7. Second springs 8 are respectively fixedly arranged inside the two moving grooves 7. The bottom parts of the two second springs 8 are respectively fixedly connected with the top ends of the two fixed blocks 4. Connecting components are respectively movably arranged inside the two moving grooves 7. One side of the bottom parts of the two connecting components is fixedly connected with one side of the power mechanism. The connecting component includes a support block 9. The support block 9 is movably arranged inside one of the moving grooves 7. The top end of the support block 9 is fixedly connected with the bottom of one of the fixed blocks 4.
