When the above equipment is replaced, since the above equipment is fixed to the connecting pipe by a clamp, it cannot be disassembled separately, resulting in too cumbersome replacement operation for the user.

[0005] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide a polyamide reverse osmosis membrane module for purification, which has the advantage of assisting in the replacement of the reverse osmosis membrane module.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A polyamide reverse osmosis membrane module for purification, comprising a reverse osmosis membrane module, a connecting pipe, a sleeve and a clamp. The inner wall of the sleeve is movably connected to the bottom surface of the connecting pipe, and the inner wall of the clamp is movably connected to the top surface of the sleeve. Both the top and bottom of the reverse osmosis membrane module are fixedly connected with docking plates, the outer side of the docking plate is movably connected to the inner side of the sleeve, and fixing mechanisms are fixedly connected to both sides of the docking plate.

[0007] Preferably, the fixing mechanism includes a guiding block. The inner side of the guiding block is fixedly connected to both sides of the docking plate. The rear side of the outer side of the guiding block is inclined. Through holes are formed in the front sides of the outer sides of the guiding blocks. Matrix blocks are arranged on the outer sides of the guiding blocks. The inner sides of the matrix blocks are fixedly connected to the inner sides of both sides of the sleeve.

A tension spring is fixedly connected to the inner side of the force-bearing block, and the other end of the tension spring is fixedly connected to the inner side of the matrix block. An unlocking component is fixedly connected to the outer side of the force-bearing block.

[0008] Preferably, the unlocking component includes an assisting handle. The inner side of the assisting handle is fixedly connected to the outer side of the force-bearing block. Rotating blocks are movably connected to the outer sides of the inner sides of the matrix blocks through pins.

[0009] Preferably, an anti-slip sleeve is fixedly sleeved on the surface of the reverse osmosis membrane module, and balls are movably embedded in the inner side of the insertion rod.

[0010] Preferably, a first sealing gasket is fixedly connected to the outer side of the docking plate, and a second sealing gasket is fixedly connected to the inner side of the sleeve. The outer side of the first sealing gasket is movably connected to the inner side of the second sealing gasket.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The utility model solves the problem that after long-term use of existing equipment, in order to ensure the water purification degree, the reverse osmosis membrane filtration component needs to be replaced. When replacing the above equipment, since the above equipment is fixed to the connecting pipe by a clamp, it cannot be disassembled separately, resulting in overly cumbersome replacement operations for users. By setting a docking plate, when the reverse osmosis membrane module reaches the end of its service life after long-term water purification and needs to be replaced, the reverse osmosis membrane module is pulled to separate the docking plate from the sleeve, and then a new reverse osmosis membrane module is connected to the sleeve through the docking plate, achieving the effect of assisting in the replacement of the reverse osmosis membrane module.

[0015] 2. The utility model sets a fixing mechanism. When the reverse osmosis membrane module is connected to the sleeve through the docking plate, the user holds the reverse osmosis membrane module and pushes it towards the sleeve, causing the docking plate to move together with the guiding block. When the docking plate moves to a certain position, the inclined surface of the guiding block first contacts the insertion rod. At this time, the docking plate continues to move, causing the insertion rod to move along the track on the inner wall of the base block under the guidance of the inclined surface of the guiding block, and the stress block moves together. Subsequently, the tension spring is stretched and deformed to generate a resilience force. Thus, when the guiding block moves to a certain position, the through hole contacts the insertion rod. At the moment of contact, the resilience force of the tension spring is released, restoring the tension spring and driving the stress block and the insertion rod to reset, and causing the insertion rod to insert into the through hole, thereby limiting and fixing the docking plate and the sleeve, and also limiting and fixing the reverse osmosis membrane module together, achieving the effect that the reverse osmosis membrane module can be quickly installed and fixed.

[0016] 3. The utility model sets an unlocking component. When the reverse osmosis membrane module reaches the end of its service life and needs to be replaced after long-term purification of filtered water, the user holds the assisting handle and pushes it, causing the stress block to move and drive the insertion rod to move. At the same time, the tension spring is stretched and deformed to generate a resilience force. Subsequently, the insertion rod is completely withdrawn from the through hole. At this time, the rotating block is rotated to contact the assisting handle to support the assisting handle, preventing the user from being unable to operate multiple assisting handles simultaneously to withdraw the insertion rod from the through hole, and once the assisting handle is released, the resilience force of the tension spring will reset the insertion rod and insert it into the through hole, which hinders the replacement of the reverse osmosis membrane module. Thus, the effect that the user can quickly disassemble and replace the reverse osmosis membrane module is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 4 shown, a polyamide reverse osmosis membrane module for purification provided by the present utility model includes a reverse osmosis membrane module 1, a connecting pipe 2, a sleeve 3 and a clamp 4. The inner wall of the sleeve 3 is movably connected to the bottom surface of the connecting pipe 2, and the inner wall of the clamp 4 is movably connected to the top surface of the sleeve 3. Both the top and bottom of the reverse osmosis membrane module 1 are fixedly connected with docking plates 5. The outer sides of the docking plates 5 are movably connected to the inner sides of the sleeves 3. Fixing mechanisms 6 are fixedly connected to both sides of the docking plates 5.

[0024] Referring to Figure 2 and Figure 4 , the fixing mechanism 6 includes a guiding block 601. The inner sides of the guiding blocks 601 are fixedly connected to both sides of the docking plate 5. The rear sides of the outer sides of the guiding blocks 601 are inclined. Through holes 602 are formed in the front sides of the outer sides of the guiding blocks 601. Base blocks 603 are arranged on the outer sides of the guiding blocks 601. The inner sides of the base blocks 603 are fixedly connected to the inner sides of both sides of the sleeve 3. Insertion rods 604 are slidably connected to the inner walls of the base blocks 603. The inner surfaces of the insertion rods 604 are movably connected to the inner walls of the through holes 602. Stress blocks 605 are fixedly connected to the outer sides of the insertion rods 604. Tension springs 606 are fixedly connected to the inner sides of the stress blocks 605. The other ends of the tension springs 606 are fixedly connected to the inner sides of the base blocks 603. Unlocking assemblies 7 are fixedly connected to the outer sides of the stress blocks 605.

[0025] As a technical optimization solution of the present utility model, by providing a fixing mechanism 6, when the reverse osmosis membrane module 1 is connected to the sleeve 3 through the docking plate 5, the user holds the reverse osmosis membrane module 1 and pushes it towards the sleeve 3, causing the docking plate 5 and the guiding block 601 to move together. When the docking plate 5 moves to a certain position, the inclined surface of the guiding block 601 first contacts the insertion rod 604. At this time, the docking plate 5 continues to move, causing the insertion rod 604 to move along the track on the inner wall of the base block 603 under the guidance of the inclined surface of the guiding block 601, and the force receiving block 605 moves together. Subsequently, the tension spring 606 is stretched and deformed to generate a resilience force. Thus, when the guiding block 601 moves to a certain position, the through hole 602 contacts the insertion rod 604. At the moment of contact, the resilience force of the tension spring 606 is released, restoring the tension spring 606 and driving the force receiving block 605 and the insertion rod 604 to reset, and causing the insertion rod 604 to insert into the through hole 602, thereby limiting and fixing the docking plate 5 and the sleeve 3, and limiting and fixing the reverse osmosis membrane module 1 together, so as to achieve the effect that the reverse osmosis membrane module 1 can be quickly installed and fixed.

[0026] Reference Figure 2 and Figure 3 For unlocking component 7, it includes a boosting handle 701. The inner side of the boosting handle 701 is fixedly connected to the outer side of the force receiving block 605. Both outer sides of the inner side of the base block 603 are movably connected by a pin with a rotating block 702.

[0027] As a technical optimization solution of the present utility model, by providing the unlocking component 7, when the reverse osmosis membrane module 1 has been used for a long time to purify and filter water and needs to be replaced when reaching the service life, the user holds the boosting handle 701 and pushes it, causing the force receiving block 605 to move and driving the insertion rod 604 to move. At the same time, the tension spring 606 is stretched and deformed to generate a resilience force. Subsequently, the insertion rod 604 is completely withdrawn from the through hole 602. At this time, rotate the rotating block 702 to contact the boosting handle 701 to support the boosting handle 701, preventing the user from being unable to operate multiple boosting handles 701 simultaneously to withdraw the insertion rod 604 from the through hole 602, resulting in the resilience force of the tension spring 606 resetting the insertion rod 604 and inserting it back into the through hole 602 after releasing the boosting handle 701, which hinders the replacement of the reverse osmosis membrane module 1. Thus, the effect that the user can quickly disassemble and replace the reverse osmosis membrane module 1 is achieved.

[0028] Reference Figure 4 A non-slip sleeve 8 is fixedly sleeved on the surface of the reverse osmosis membrane module 1, and a ball 9 is movably embedded in the inner side of the insertion rod 604.

[0029] As a technical optimization solution of the present utility model, by providing an anti-slip sleeve 8 and a ball 9, when the user connects the reverse osmosis membrane module 1 to the sleeve 3 using the docking plate 5, and finally inserts the insertion rod 604 into the through hole 602 by squeezing the insertion rod 604 through the guiding block 601 to limit and fix the reverse osmosis membrane module 1, the user first holds the area of the reverse osmosis membrane module 1 with the anti-slip sleeve 8 to avoid the reverse osmosis membrane module 1 being too smooth and having no good grasping points. Then, the user moves the reverse osmosis membrane module 1. Subsequently, as the guiding block 601 approaches the insertion rod 604, before the insertion rod 604 touches the inclined surface of the guiding block 601, the ball 9 on the insertion rod 604 contacts the inclined surface of the guiding block 601 first and rolls along the trajectory of the inclined surface of the guiding block 601, thus isolating the direct contact between the insertion rod 604 and the guiding block 601, reducing the contact area, decreasing the frictional resistance, and improving the working efficiency of the user.

[0030] Reference Figure 2 , a first gasket 10 is fixedly connected to the outside of the docking plate 5, and a second gasket 11 is fixedly connected to the inside of the sleeve. The outside of the first gasket 10 is movably connected to the inside of the second gasket 11.

[0031] As a technical optimization solution of the present utility model, by providing the first gasket 10 and the second gasket 11, during the connection and closing process of the docking plate 5 and the sleeve 3, the first gasket 10 and the second gasket 11 come into contact and are squeezed, increasing the contact area between the docking plate 5 and the sleeve 3 and reducing the gap at the connection, preventing water from overflowing through the gap at the connection between the docking plate 5 and the sleeve 3 when water enters the reverse osmosis membrane module 1 through the connecting pipe 2, thereby improving the sealing performance when the docking plate 5 and the sleeve 3 are connected and closed.

[0032] Reference Figure 2 , guiding blocks 12 are fixedly connected to the inner sides of the outer sides of the guiding block 601, and the outside of the guiding block 12 is movably connected to the inside of the insertion rod 604.

[0033] As a technical optimization solution of the present utility model, by providing the guiding block 12, during the process that the user squeezes the insertion rod 604 through the guiding block 601 and finally inserts the insertion rod 604 into the through hole 602, the user moves the reverse osmosis membrane module 1, causing the docking plate 5 and the guiding block 601 to approach the insertion rod 604 together, and squeezing and pushing the insertion rod 604 through the guiding block 601. While moving, the insertion rod 604 moves along the trajectory of the guiding block 12 together, thereby assisting the user in pushing the reverse osmosis membrane module 1 and preventing the movement trajectory from being erratic when the user pushes the reverse osmosis membrane module 1, making it difficult for the insertion rod 604 to insert into the through hole 602, and thus improving the stability when the insertion rod 604 inserts into the through hole 602 when the user pushes the reverse osmosis membrane module 1.

[0034] Reference Figure 1 , on both sides of the front surface of the docking plate 5, limiting blocks 13 are fixedly connected, and the inner sides of the front surfaces of the two sides of the limiting blocks 13 are movably connected to the inner side of the front surface of the sleeve.

[0035] As a technical optimization scheme of the present utility model, by providing the limiting blocks 13, when the user pushes the reverse osmosis membrane module 1 and the insertion rod 604 is quickly inserted into the through hole 602 with the assistance of the guiding block 12 for limiting, as the insertion rod 604 approaches the through hole 602 quickly, at the moment when the insertion rod 604 is completely fitted with the through hole 602, the limiting block 13 moving together with the reverse osmosis membrane module 1 contacts the sleeve 3 and prevents the reverse osmosis membrane module 1 from continuing to move, thereby preventing the user from pushing the reverse osmosis membrane module 1 too quickly along the movement track of the guiding block 12, so that the resilience generated by the stretching deformation of the tension spring 606 due to the movement of the force receiving block 605 caused by the extrusion of the insertion rod 604 by the guiding block 601 before cannot quickly react to insert the insertion rod 604 into the through hole 602, thus improving the working efficiency of the user.

[0036] Working principle and usage process of the present utility model: When in use, the user first connects the connecting pipe 2 to an external water pipe, then sleeves the sleeve 3 on the connecting pipe 2, and then rotates the sleeve 3 according to the orientation of the base block 603 on the sleeve 3. After the orientation adjustment is completed, the sleeve 3 and the connecting pipe 2 are firmly connected through the clamp 4. Then, hold the reverse osmosis membrane module 1 and push it towards the sleeve 3, so that the docking plate 5 and the guide block 601 move together. When the docking plate 5 moves to a certain position, the inclined surface of the guide block 601 first contacts the insertion rod 604. At this time, the docking plate 5 continues to move, so that the insertion rod 604 moves along the track of the inner wall of the base block 603 under the guidance of the inclined surface of the guide block 601, and the force receiving block 605 moves together. Subsequently, the tension spring 606 is stretched and deformed to generate a resilience force. Thus, when the guide block 601 moves to a certain position, the through hole 602 contacts the insertion rod 604. At the moment of contact, the resilience force of the tension spring 606 is released, restoring the tension spring 606 and driving the force receiving block 605 and the insertion rod 604 to reset, and making the insertion rod 604 insert into the through hole 602, so that the docking plate 5 and the sleeve 3 are limited and fixed, and the reverse osmosis membrane module 1 is also limited and fixed together, thereby stably connecting the reverse osmosis membrane module 1 and the connecting pipe 2. Then, water enters the reverse osmosis membrane module 1 through the connecting pipe 2 at one end, passes through the docking plate 5 and the sleeve 3, and is discharged from the connecting pipe 2 at the other end after purification and filtration. Then, when the reverse osmosis membrane module 1 has been used for a long time to purify water and needs to be replaced when reaching the service life, the user holds the assisting handle 701 and pushes it, so that the force receiving block 605 moves and drives the insertion rod 604 to move. At the same time, the tension spring 606 is stretched and deformed to generate a resilience force. Subsequently, the insertion rod 604 is completely withdrawn from the through hole 602. At this time, rotate the rotating block 702 to contact the assisting handle 701 to support the assisting handle 701. At this time, the reverse osmosis membrane module 1 can be pulled to separate the docking plate 5 and the sleeve 3, and then replaced, thus having the advantage of assisting in the replacement of the reverse osmosis membrane module 1.

[0037] To sum up: For this polyamide reverse osmosis membrane module for purification, by setting the docking plate 5, when the reverse osmosis membrane module 1 has been used to purify water for a long time and needs to be replaced when reaching the service life, pull the reverse osmosis membrane module 1 to separate the docking plate 5 and the sleeve 3, and then connect a new reverse osmosis membrane module 1 and the sleeve 3 through the docking plate 5, which is convenient for replacement.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
