[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] Please see the appendix Figures 1-6 This invention discloses a device for installing and disassembling the end cap of a reverse osmosis membrane in a purified water station of a biological products workshop.

[0030] The reverse osmosis membrane end cap installation and disassembly device for a purified water station in a bioproduct workshop provided by this utility model includes a fixing component and a rectangular force plate 12. The fixing component is detachably installed on the reverse osmosis membrane housing 10, and the rectangular force plate 12 is detachably installed on the fixing component. An installation and disassembly screw 13 is screwed to the center of the rectangular force plate 12. An installation and disassembly connector 14 is rotatably connected to one end of the installation and disassembly screw 13 facing the reverse osmosis membrane housing 10. The installation and disassembly connector 14 is detachably connected to the reverse osmosis membrane end cap 11 installed inside the port of the reverse osmosis membrane housing 10.

[0031] The reverse osmosis membrane end cap 11 is installed inside the reverse osmosis membrane housing 10. The fixing assembly includes clamps A61 and B62 symmetrically arranged around the outer wall of the reverse osmosis membrane housing 10. U-shaped fixing angle irons A41 and B42 are installed on clamps A61 and B62 by fixing nuts and screws. The rectangular force plate 12 is installed on U-shaped fixing angle irons A41 and B42 by fixing nuts and screws. The installation and removal screw 13 is installed on the rectangular force plate 12 by threaded connection. The installation and removal connector 14 is installed on the installation and removal screw 13 by hexagonal head bolts 15.

[0032] Clamps A61 and B62 are installed on the reverse osmosis membrane housing 10 using fixing nuts B102, C103, F106, G107, C31, and D32, forming the foundation of the entire device. U-shaped fixing angle irons A41 and B42 are installed on the clamps using fixing nuts A101, D104, E105, H108, and fixing screws 31 and 32, sharing fixing screws C31 and D32 with clamps A61 and B62. The rectangular load-bearing plate 12 is mounted on U-shaped fixing angle irons A41 and B42 using fixing nuts J109, K110, L111, M112, N113, P114, Q115, R116, fixing screws A21 and B22. The installation and removal screw 13 is threaded onto the rectangular load-bearing plate 12. Fixing screws A21 and B22 serve as load-bearing screws. The diameters of the through holes A121 and B122 on the rectangular load-bearing plate 12 are larger than the diameters of the fixing screws A21 and B22, allowing adjustment of the distance between the rectangular load-bearing plate 12 and the reverse osmosis membrane end cap 11 to suit different needs. The thread of the installation and removal screw 13 mates with the thread 123 on the rectangular load-bearing plate 12. By placing the installation and removal screw 13 into the thread 123 with tools such as an Allen wrench, the installation and removal screw 13 can be easily rotated. The installation and removal connector 14 is installed on the installation and removal screw 13 by means of a hexagonal head bolt 15.

[0033] It should be noted that the through hole C141 on the installation / disassembly connector 14 is unthreaded and its diameter is larger than the screw diameter of the hexagonal head bolt 15. The depth of the threaded hole B132 of the installation / disassembly screw 13 is less than the screw length of the hexagonal head bolt 15. After the installation / disassembly connector 14 is installed on the installation / disassembly screw 13 via the hexagonal head bolt 15, the installation / disassembly connector 14 can rotate freely to accommodate different angles of the end cap 11. When the installation / disassembly screw 13 is rotated, the installation / disassembly connector 14 exerts a vertical tensile or vertical pushing force on the reverse osmosis membrane end cap 11, thereby disassembling or installing the reverse osmosis membrane end cap 11.

[0034] The installation / disassembly connector 14 is designed with openings of different widths. Opening B143 connects opening A142 and the end face of the installation / disassembly connector 14 facing the reverse osmosis membrane end cap 11. The width of opening B143 is smaller than the width of opening A142. Opening A142 bears the vertical tensile or vertical pushing force during the installation and disassembly of the end cap 11. Therefore, this device not only meets the requirements of safe production and saves manpower and material resources, but also makes installation and disassembly safer and more labor-saving, improving maintenance efficiency.

[0035] The installation sequence when using the reverse osmosis membrane end cap installation and removal device of this utility model is as follows:

[0036] Secure clamps A61 and B62 to the reverse osmosis membrane housing 10; place fixing nuts B102 and C103 and U-shaped fixing angle iron B42 in their respective positions, aligning the center holes, and use fixing screw D32 to pass through fixing nut B102, clamp A61, clamp B62, and fixing nut C103 sequentially from top to bottom; place fixing nuts G107 and F106 and U-shaped fixing angle iron A41 in their respective positions, aligning the center holes, and use fixing screw C31 to pass through fixing nut G107, clamp A61, and clamp B62 sequentially from top to bottom. 2. Fix nut F106; adjust and tighten fixing nuts B102, C103, G107, and F106; install fixing nuts A101 and D104 onto fixing screw D32 and tighten them respectively; install fixing nuts H108 and E105 onto fixing screw C31 and tighten them respectively; install fixing nut K110 onto screw A21, then pass fixing screw A21 through the hole in U-shaped fixing angle iron B42, install fixing nut J109, and fix fixing nut J109. Install the set nut K110; install the set nut Q115 on the set screw B22, then pass the set screw B22 through the hole of the U-shaped set angle iron A41, install the set nut R116, and tighten the set nut Q115 and set nut R116; install the set nut L111 on the set screw A21, and install the set nut P114 on the set screw B22; install the installation / removal screw 13 on the rectangular load-bearing plate 12 through the thread 123; install the installation / removal connector 14 on the screw 13 using a hexagonal head bolt 15; install the rectangular load-bearing plate 12 on... Adjust fixing nuts L111 and P114 on fixing screws A21 and B22 until the installation / disassembly connector 14 locks the end cap 11. Install fixing nut M112 onto fixing screw A21 and fixing nut N113 onto fixing screw B22. Adjust the positions of fixing nuts L111, M112, N113, and P114 sequentially until the rectangular force-bearing plate 12 is horizontal. Then, tighten fixing nuts L111, M112, N113, and P114. Once the entire device is installed, rotating the installation / disassembly screw 13 applies a vertically pulling or pushing force to the reverse osmosis membrane end cap 11, thereby allowing for the removal or installation of the reverse osmosis membrane end cap 11.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
