Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC pipe technology, specifically to a quick-sealing connection PVC pipe structure. Background Technology
[0002] PVC pipe, also known as rigid polyvinyl chloride pipe, is a type of pipe made by hot-pressing polyvinyl chloride resin with stabilizers, lubricants, and other additives. It has many advantages such as strong corrosion resistance and low price, and is often used for fluid transportation. When connecting and fixing the ends of PVC pipes, the connection points need to be sealed to prevent the internal fluid from leaking out.
[0003] However, most existing PVC pipe connections use hot-melt, adhesive bonding, or connection structures. But when facing large-scale projects, there are too many connection points in the pipes, and the hot-melt bonding requires waiting for the hot-melt machine to heat up, making the hot-melt connection inefficient. Adhesive bonding requires the use of adhesives, which may contaminate the fluid inside the pipe. Connection structures mostly use multiple claw-shaped joints to compress gaskets for sealing, but because the strength of the claw-shaped structure at the root is low, it may break after long-term use or when tightening the outer second conical plate. In addition, because there are certain gaps between the claw-shaped structures, the sealing performance is poor, which makes it difficult to promote its use.
[0004] To address this problem, this application provides a quick-sealing connection PVC pipe structure. Utility Model Content
[0005] The purpose of this utility model is to provide a quick-sealing connection PVC pipe structure to solve the problems mentioned in the background art, which are that most PVC pipe connections are made by hot melting, glue bonding or using connection structures, resulting in low efficiency, pollution of the fluid inside the pipe, poor sealing and poor performance.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A quick-sealing PVC pipe structure includes a male connector assembly, a female connector assembly, and a water pipe. The male connector assembly includes a clamping ring, a first conical plate, and a first washer. The first conical plate is disposed on the outside of the water pipe. Both the male and female connector assemblies are movably connected to the outside of the water pipe. The female connector assembly includes a connecting ring, a third washer, and a second conical plate. The connecting ring is movably installed on the outside of the second conical plate, and the third washer is fixedly installed inside the second conical plate. The second conical plate is disposed on the outside of the water pipe. The first and second conical plates are both threadedly connected to the outside of the first and second conical plates, and the first washer is fixedly installed inside the first and second conical plates.
[0007] A further improvement of the present invention is that a retaining ring is provided at one end of the first conical plate, and the outer side of the retaining ring is provided with threads.
[0008] A further improvement of this utility model is that: the washer is movably connected to the outside of the water pipe, and the first conical plate and the second conical plate are both provided with connecting holes, and a connecting rod is movably installed inside the connecting holes.
[0009] A further improvement of this utility model is that: the third washer is movably connected to the outside of the water pipe, and both the third washer and the first washer have compression grooves on their outer sides.
[0010] A further improvement of this utility model is that: both the first conical plate and the second conical plate have mounting grooves inside, and mounting plates are fixedly installed inside the mounting grooves.
[0011] A further improvement of this utility model is that: the inner side of the mounting plate is fixedly connected with teeth, and the ends of the teeth are movably connected to the outside of the water pipe.
[0012] A further improvement of this utility model is that: a connecting groove is provided at the end of the second conical plate, and a washer is fixedly installed inside the connecting groove.
[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a quick-sealing connection PVC pipe structure. Under the combined action of the clamping ring, the first conical plate, the first washer, the connecting ring, the third washer, and the second conical plate, by rotating the two clamping rings, the clamping rings apply a certain pressure to the first and second conical plates, so that the first and second conical plates press the first and third washers onto the water pipe. Then, by rotating the connecting ring, the first and second conical plates are connected. The operation is simple and quick, improving the connection efficiency of water pipes.
[0014] 2. This utility model provides a quick-sealing connection PVC pipe structure. Through the combined action of the first conical plate, washer one, washer three, and the second conical plate, the first and second conical plates are set into two semi-circular rings, increasing the stress area and thus increasing its strength, preventing it from breaking easily. When the compression ring is tightened, washer one seals the connection between the first and second conical plates and the water pipe, while washer three seals the connection between the two water pipes. The use of multiple seals improves the sealing performance of the water pipe. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, this utility model provides a quick-sealing connection PVC pipe structure, including a male connector assembly 1, a female connector assembly 2, and a water pipe 3. The male connector assembly 1 includes a clamping ring 10, a first conical plate 11, and a washer 14. The first conical plate 11 is disposed outside the water pipe 3. Both the male connector assembly 1 and the female connector assembly 2 are movably connected to the outside of the water pipe 3. A retaining ring 12 is provided at one end of the first conical plate 11, and the outer side of the retaining ring 12 is threaded. The washer 14 is movably connected to the outside of the water pipe 3. Both the first conical plate 11 and the second conical plate 22 have connecting holes 15 inside, and a connecting rod 13 is movably installed inside the connecting holes 15. The outer sides of the first conical plate 11 and the second conical plate 22 are threadedly connected to a clamping ring. An internal washer 14 is fixedly installed in both the ring 10, the first conical plate 11, and the second conical plate 22. When the two clamping rings 10 are rotated, the pressure of the clamping rings 10 on the first conical plate 11 and the second conical plate 22 will increase as the outer sides of the first conical plate 11 and the second conical plate 22 are conical and the diameter increases further away from the clamping rings 10. This causes the first conical plate 11 and the second conical plate 22 to press the washer 14 and the washer 21 onto the water pipe 3. The washer 14 seals the connection between the first conical plate 11, the second conical plate 22 and the water pipe 3, and the washer 21 seals the connection between the two water pipes 3. By using multiple seals, the sealing performance of the water pipe 3 is improved.
[0018] like Figure 2-5As shown, the female connector assembly 2 includes a connecting ring 20, a third washer 21, and a second conical plate 22. The connecting ring 20 is movably installed on the outside of the second conical plate 22. By screwing the connecting ring 20 into the thread on the retaining ring 12, the two sections of water pipe 3 are connected. The third washer 21 is fixedly installed inside the second conical plate 22. The second conical plate 22 is located outside the water pipe 3, and the third washer 21 is movably connected to the outside of the water pipe 3. Compression grooves 28 are provided on the outer sides of both the third washer 21 and the first washer 14. By providing compression grooves 28 on the first washer 14 and the third washer 21, the pressure drop between the two first conical plates 11 and the first washer 14 can be eliminated. The gap between the two second conical plates 22 allows the first washer 14 and the third washer 21 to fit the water pipe 3 more closely. The end of the second conical plate 22 is provided with a connecting groove 23, and the second washer 26 is fixedly installed inside the connecting groove 23. The first conical plate 11 and the second conical plate 22 are both provided with mounting grooves 27, and the mounting plate 24 is fixedly installed inside the mounting groove 27. The inner side of the mounting plate 24 is fixedly connected with teeth 25, and the ends of the teeth 25 are movably connected to the outside of the water pipe 3. When connecting, the teeth 25 on the mounting plate 24 will be engaged in the water pipe 3 to prevent the connection structure from shifting on the water pipe 3.
[0019] The working principle of this quick-sealing PVC pipe structure will be explained in detail below.
[0020] like Figure 1-5As shown, when using this quick-sealing PVC pipe structure, the male connector 1 and female connector 2 are respectively fitted onto the ends of the water pipes 3 to be connected. When connecting the water pipes 3, the two water pipes 3 are brought close together, so that the second washer 26 contacts the end of the first conical plate 11. At the same time, one end of the third washer 21 in the second conical plate 22 is inserted into the interior of the first conical plate 11. Then, the two clamping rings 10 are rotated. Since the outer sides of the first conical plate 11 and the second conical plate 22 are conical, and the diameter increases further away from the clamping ring 10, the pressure of the clamping ring 10 on the first conical plate 11 and the second conical plate 22 will increase as the clamping ring 10 is rotated. This causes the first conical plate 11 and the second conical plate 22 to press the first washer 14 and the third washer 21 onto the water pipe 3. In addition, the teeth 25 on the mounting plate 24 will engage with the water pipe 3 to prevent the connection structure from producing defects on the water pipe 3. The displacement is reduced, and the compression grooves 28 on the first washer 14 and the third washer 21 eliminate the gap between the two first conical plates 11 and the two second conical plates 22, allowing the first washer 14 and the third washer 21 to fit the water pipe 3 more closely. Then, the connecting ring 20 is rotated and screwed into the thread on the retaining ring 12 to connect the two sections of water pipe 3. The operation is simple and quick, improving the connection efficiency of the water pipe 3. At the same time, when the clamping ring 10 is tightened, the connection between the first conical plate 11, the second conical plate 22 and the water pipe 3 is sealed by the first washer 14, and the connection between the two water pipes 3 is sealed by the third washer 21. The sealing performance of the water pipe 3 is improved by using multiple seals. At the same time, the first conical plate 11 and the second conical plate 22 are set into two semi-circular rings to increase the stress area, thereby increasing their strength and preventing them from breaking easily.
[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
