[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] like Figures 1-4As shown, the fixture for testing the weather resistance of PVC film includes two columns 2, with a base plate 1 fixed on each column 2. A crossbeam 3 connects the columns 2 via an adjustable component. Several test platforms 4 are mounted on the crossbeam 3. In this embodiment, there are three test platforms 4, which can be selected according to actual needs. They can be installed by welding. The test platforms 4 are arranged at an angle, and upper and lower retaining strips 8 are horizontally installed on each test platform 4. In this embodiment, each test platform 4 has two sets of upper and lower retaining strips 8, which can be installed on the test platform 4 using fasteners. Specifically, a limiting head 5 is also installed on the test platform 4, and the limiting head 5 is located between the upper and lower retaining strips 8. The limiting head 5 can be welded. The installation is carried out by means of a snap-fit connection; with this structure, four detachable shelves 6 can be installed on each test platform 4; the detachable shelves 6 are installed by snap-fit connection between the upper and lower clips 8, and the detachable shelves 6 are connected to the upper and lower pressure plates 9 by hinges 7. Each of the upper and lower pressure plates 9 has a magnet 16, and the detachable shelves 6 has a magnet 17 that attracts the magnet 16. In practice, the surface of the magnet 17 is flush with the surface of the detachable shelves 6. With this structure, the PVC film 10 is placed on the detachable shelves 6, the upper and lower pressure plates 9 are closed, the PVC film 10 is pressed on the detachable shelves 6, and then the detachable shelves 6 are snapped onto the test platform 4.
[0019] The detachable shelf 6 also has a handle 11 on one side.
[0020] The adjustable component includes an adjusting seat 12, a locking screw 13, and a connecting block 15. The adjusting seat 12 is slidably connected to the column 2, and the locking screw 13 is threadedly connected to the adjusting seat 12. The adjusting seat 12 is connected to the connecting block 15 through a connecting rod 14, and the connecting block 15 is connected to the end of the crossbeam 3. With this structure, the height of the crossbeam 3 can be adjusted by adjusting the adjusting seat 12.
[0021] The test bench 4, upper and lower retaining strips 8, detachable shelf 6, upper and lower pressure plates 9, and hinge 7 are all made of stainless steel.
[0022] In this invention, the PVC film 10 to be tested is fixed on a detachable shelf 6, and the shelf is installed on the test platform. This allows for simultaneous weather resistance testing of multiple PVC films 10. Moreover, the disassembly and installation of the PVC film 10 are simple and easy to perform as needed. The test condition is that the entire fixture is placed directly in an outdoor environment.
