[0032] Four mounting mechanisms are arranged around the pipe wall of the pressure water pipe 3, each mounting mechanism is connected to a U-shaped rod 10, the other end of each U-shaped rod 10 is fixedly connected to a U-shaped plate 11, a rotating rod 12 is rotatably arranged inside each U-shaped plate 11, and a roller 13 is fixedly sleeved on the rod wall of each rotating rod 12, and four triangular blocks 14 are fixedly arranged around the pipe wall of the pure water pipe 5, each roller 13 is contacted and connected with the inclined surface of the corresponding triangular block 14, and by utilizing the set rollers 13 and triangular blocks 14, the pure water pipe 5 can be driven close to the pressure water pipe 3 when the roller 13 approaches the triangular block 14, thereby realizing the installation or disassembly of the reverse osmosis membrane 7, thereby effectively simplifying the disassembly and assembly process of the product osmosis membrane.

[0033] like Figure 1-4 As shown, the installation mechanism includes a U-shaped frame 15 and a gear 16. The U-shaped frame 15 is fixedly arranged on the pipe wall of the pressure water pipe 3 and a fixed rod 17 is fixedly sleeved inside. The gear 16 is rotatably sleeved on the rod wall of the fixed rod 17. One end of the U-shaped rod 10 is fixedly connected to the side of the gear 16. A rack 18 is meshed on the side of the gear 16. The rack 18 is movably penetrated into the interior of the U-shaped frame 15. A driving mechanism is arranged on the pipe wall of the pressure water pipe 3.
