[0002] Reverse osmosis membranes are artificial semi-permeable membranes with certain characteristics, made by simulating biological semi-permeable membranes. The principle of reverse osmosis technology is that, under the action of pressure higher than that of the solution, other substances cannot pass through the semi-permeable membrane, thus separating these substances from water. The membrane pore size of reverse osmosis membranes is very small, so they can effectively remove dissolved salts, microorganisms, organic matter, etc. from water.

However, during the disassembly and cleaning of existing reverse osmosis membrane modules, the end caps and the inner side of the cylinder are tightly connected and difficult to pull out. When prying the end caps, wear can easily occur at the connection between the cylinder and the end caps, leading to water leakage and affecting the normal use of the reverse osmosis membrane modules.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5 One embodiment provided by this utility model:
[0025] A reverse osmosis membrane module, comprising:
[0026] The main body includes a membrane body 1, with a central tube 11 extending through its surface. A cylindrical body 12 and end caps 13 are mounted on the surface of the membrane body 1.

A locking screw 17 and an interface piece 18 are mounted on the surface of the sleeve cap 16. When assembling the reverse osmosis membrane module, the membrane body 1 and the central tube 11 are first installed on the inner surface of the cylindrical body 12. Then, two sets of end caps 13 are inserted into both ends of the cylindrical body 12 and pressed against the surface of the membrane body 1. Next, clamp 14 is engaged at the connecting edge of end cap 13 and cylinder 12, and sleeve cap 16 is fitted onto the surface of end cap 13 and clamp 14. At the same time, sleeve cap 16 is fixed by connecting locking screw 17 and threaded pipe 15. Finally, interface piece 18 is installed on the surface of end cap 13 through sleeve cap 16. There are two sets of interface pieces 18. One set of interface pieces 18 is connected to the central pipe 11 to flow the treated water, while the other set of interface pieces 18 is used to flow the raw water. There are two interface pieces 18 in each set and they are set at both ends of cylinder 12.
[0027] The pulling mechanism includes an annular groove 2, which is formed on the surface of the end cap 13. A handle 21 is movably connected to the surface of the annular groove 2. A rotating hole 22 is formed on the surface of the handle 21. A rotating block 23 is rotatably connected to the surface of the rotating hole 22. A fixing block 24 is fixedly connected to the surface of the rotating block 23. A slot 25 and a threaded groove 28 are formed on the surface of the end cap 13. A groove 26 and an insertion hole 27 are formed on the surface of the fixing block 24. A screw 29 is installed on the surface of the fixing block 24. The handle 21 can be installed through the annular groove 2, and the outer diameter of the annular groove 2 is larger than the outer diameter of the handle 21.
[0028] Furthermore, two sets of rotating holes 22 are provided, and the two sets of rotating holes 22 are opened at both ends of the handle 21. The diameter of the rotating holes 22 is the same as the diameter of the rotating block 23. With the connection between the rotating holes 22 and the rotating block 23, the handle 21 can rotate around the rotating block 23 as the center. The handle 21 rotates on the surface of the rotating block 23 through the rotating holes 22. One side of the rotating block 23 is engaged with the surface of the annular groove 2, while the other side is fixed to the surface of the fixing block 24.
[0029] Furthermore, there are two sets of fixing blocks 24 and slots 25. The two sets of fixing blocks 24 are installed at both ends of the handle 21, and the two sets of slots 25 are opened on both sides of the annular groove 2. The fixing blocks 24 are engaged with the surface of the slots 25. The size of the slots 25 is the same as that of the fixing blocks 24. With the connection of the fixing blocks 24 and the slots 25, the handle 21 and the end cap 13 can be connected.
[0030] Furthermore, the diameter of the groove 26 is larger than the diameter of the socket 27. The screw 29 is inserted into the surface of the socket 27. One end of the screw 29 is threaded into the surface of the threaded groove 28, and the other end of the screw 29 is abutted into the surface of the groove 26. The groove 26 allows the screw 29 to be placed on its surface and ensures the flatness of the end cap 13 surface. The screw 29 passes through the surface of the fixing block 24 through the groove 26 and the socket 27.
[0031] Furthermore, the surface of the cover 16 is provided with a limiting mechanism, which includes a limiting plate 3. The limiting plate 3 is movably connected to the inner surface of the cover 16. A sleeve plate 31 is fixedly connected to the inner surface of the cover 16. A slider 32 is fixedly connected to the surface of the limiting plate 3. A sliding groove 33 is opened on the surface of the sleeve plate 31. A support spring 34 is installed on the inner surface of the sleeve plate 31. An arc-shaped groove 35 is opened on the surface of the limiting plate 3. The diameter of the arc-shaped groove 35 is the same as the outer diameter of the threaded tube 15. The arc-shaped groove 35 opened on the limiting plate 3 allows the limiting mechanism to fit more closely to the threaded tube 15 and makes the limiting effect better.
[0032] Furthermore, the cross-section of the limiting plate 3 is U-shaped. One side of the limiting plate 3 is slidably connected to the surface of the threaded tube 15 through the arc groove 35, and the other side of the limiting plate 3 is slidably connected to the inner surface of the sleeve plate 31. Two sets of sleeve plates 31 are provided, and the two sets of sleeve plates 31 are installed on both sides of the locking screw 17. Through the connection between the limiting plate 3 and the sleeve plate 31, the limiting length can be extended, and the limiting mechanism can be better engaged on the threaded tube 15 during use.
[0033] Furthermore, the slider 32 is slidably connected to the surface of the groove 33. Two sets of support springs 34 are provided, and the two sets of support springs 34 are installed on both sides of the sleeve plate 31. One end of the support spring 34 is fixedly connected to the surface of the limiting plate 3, and the other end of the support spring 34 is fixedly connected to the inner surface of the cover 16. With the connection of the slider 32 and the groove 33, the limiting plate 3 can be limited and prevented from falling off the sleeve plate 31. At the same time, under the action of the support spring 34, a supporting force can be applied to the surface of the limiting plate 3 to keep the total length of the limiting plate 3 and the sleeve plate 31 at its maximum before installation, and to reduce the influence of sliding resistance when the limiting plate 3 is inserted.
[0034] Working principle: Before installing the upper end cap 13 of the reverse osmosis membrane module, first place the two sets of rotating blocks 23 on the outside of the handle 21 and insert them into the rotating holes 22. Then, snap the fixing block 24 into the surface of the slot 25 and align the groove 26, the insertion hole 27 and the threaded groove 28. At this time, insert the screw 29 into the insertion hole 27 and connect one end to the surface of the threaded groove 28 through the thread. After tightening the screw 29, the other end rests against the surface of the groove 26, thus completing the installation of the handle 21. When removing the end cap 13, simply rotate the handle 21 around the rotating block 23, and then pull the handle 21 to remove the end cap 13 from the inside of the cylinder 12.
[0035] When installing the cover 16, the supporting force applied by the support spring 34 on the limiting plate 3 causes the slider 32 to abut against the surface of the groove 33. First, align the surfaces of the two arc grooves 35 with the outside of the threaded tube 15 and insert them. Because there is friction when the arc groove 35 contacts the threaded tube 15, the limiting plate 3 slides on the surface of the threaded tube 15 and the cover 31 during the insertion process, and drives the slider 32 to slide on the surface of the groove 33. At this time, the cover 16 is fitted on the surface of the end cover 13 and the clamp 14, and the hole of the locking screw 17 is aligned with the threaded tube 15. Then the locking screw 17 and the threaded tube 15 can be connected by threads to fix the cover 16.
