[0001] This application relates to the field of irrigation technology, and in particular to a flexible quick-connect coupling. Background Technology

[0002] With the continuous development of agricultural modernization, automated irrigation technology has been widely adopted. For example, in drip irrigation and flood irrigation systems, modern irrigation typically employs large-scale pipe networks. These networks include main water supply pipes and irrigation branch pipes laid out and assembled on the field. Chinese Patent Publication No. CN101267730A discloses a multi-layered irrigation pipe with holes in its wall, into which flexible quick-connect fittings are installed to connect to external irrigation branch pipes. However, in practice, this solution usually requires pre-installing flexible quick-connect fittings in the holes of the irrigation pipe, allowing the pipe to be held in place by the connector. However, after prolonged use, the connection between the connector and the irrigation pipe is prone to loosening at the welded joints, leading to leaks and low reliability. Therefore, designing a technology to improve reliability is the technical problem this application aims to solve. Summary of the Invention

[0003] This application provides a flexible quick-connect coupling to reduce water leakage at the flexible quick-connect coupling during use, thereby improving reliability.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] This application provides a flexible quick-connect coupling, comprising:

[0006] A first connector is provided with a first through hole, a connecting plate is provided at one end of the first connector, and a first threaded portion is also provided on the first connector, with the first through hole also penetrating the connecting plate;

[0013] The two adjacent second annular ribs are configured to form an outer sealing zone on the pipe wall of the water supply pipe.

[0014] Furthermore, the first threaded portion is a first external thread segment formed on the outer periphery of the first connector;

[0015] The second threaded portion is formed by forming a first internal threaded hole at one end of the second through hole;

[0016] The first external thread segment is threaded into the first internal thread hole.

[0050] Example 1, as Figures 1-4 and Figure 9 As shown, this application provides a flexible quick-connect coupling, comprising:

[0051] A first connector 1 is provided with a first through hole 11, a connecting plate 12 is provided at one end of the first connector 1, and a first threaded portion 10 is also provided on the first connector 1. The first through hole 11 also penetrates the connecting plate 12.

[0052] The second connector 2 is provided with a second through hole 21 and a second threaded portion 211.

[0053] The second connector 2 is connected to the first connector 1 through the second threaded portion 211 and the first threaded portion 10, and a clamping and sealing space is formed between the second connector 2 and the connecting plate 12.

[0054] The clamping sealing space is configured to clamp the wall of the main water supply pipe;

[0055] In addition, the surface of the connecting plate 12 opposite to the second connecting member 2 is provided with at least one first annular rib 15, the first annular rib 15 surrounding the outer periphery of the first through hole 11; and / or, the end face of the second connecting member 2 opposite to the connecting plate 12 is provided with at least one second annular rib 22, the second annular rib 22 surrounding the outer periphery of the second through hole 21.

[0056] Specifically, the flexible quick-connector in this application is assembled from a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 cooperate to be assembled into the opening 31 provided on the main water supply pipe 3, so that the water in the main water supply pipe 3 can flow out through the first through hole 11 and the second through hole 21. An irrigation branch pipe is connected to the second connector 2, so that the water flowing out from the second through hole 21 will enter the irrigation branch pipe and flow to the corresponding irrigation area.

[0057] Since the first connector 1 and the second connector 2 clamp the main water supply pipe 3 by means of a threaded connection, the clamped part of the main water supply pipe 3 needs to achieve good water tightness. For this purpose, a first annular rib 15 can be provided on the connecting plate 12 of the first connector 1, and similarly, a second annular rib 22 can be provided on the second connector 2.

[0058] After connecting the first connector 1 and the second connector 2 together and clamping the wall of the main water supply pipe 3, the first annular rib 15 and / or the second annular rib 22 will press more firmly against the wall of the main water supply pipe 3. In this way, a good water seal can be achieved at the clamped part of the main water supply pipe 3.

[0059] Furthermore, taking the second annular rib 22 provided on the second connector 2 as an example, the sealing treatment of the opening 31 by the second annular rib 22 will be explained.

[0060] The second connector 2 has a protruding second annular rib 22 on its end face opposite to the connecting plate 12. After the second connector 2 is connected to the first connector 1 and the wall of the main water supply pipe 3 is sandwiched between them, the second annular rib 22 will further press against the outer wall of the main water supply pipe 3. At the same time, the second annular rib 22 is also distributed around the periphery of the opening 31. In this way, the second annular rib 22 further presses the pipe wall around the opening 31 onto the connecting plate 12, effectively improving the sealing performance of the opening 31.

[0061] As needed, multiple second annular ribs 22 can be provided on the end face of the second connector 2, and the multiple second annular ribs 22 are arranged concentrically.

[0062] The two adjacent second annular ribs 22 are configured to form an outer sealing area on the pipe wall of the water supply pipe.

[0063] Specifically, multiple second annular ribs 22 tightly press the wall of the main water supply pipe 3 onto the connecting plate 12, and an outer sealing area with good sealing performance is formed between two adjacent second annular ribs 22. The outer sealing area surrounds the opening 31 to improve the sealing performance of the outer periphery of the opening 31.

[0064] Similarly, when the connecting plate 12 is equipped with a first annular rib 15, the connecting plate 12 is provided with multiple first annular ribs 15, which are arranged concentrically.

[0065] The two adjacent first annular ribs 15 are configured to form an inner sealing zone on the pipe wall of the water supply pipe.

[0066] In one embodiment of this application, the physical representation of the first threaded portion 10 and the second threaded portion 211 can take many forms.

[0067] For example: the first threaded portion is a first external thread segment formed on the outer circumference of the first connector; the second threaded portion is a first internal threaded hole formed at one end of the second through hole; wherein, the first external thread segment is threadedly connected to the first internal threaded hole.

[0068] Alternatively, the first threaded portion is a second internal threaded hole formed on the inner wall of the first through hole; the second connector is also provided with an extension portion, the second through hole also penetrates the extension portion, and the second threaded portion is a second external threaded segment formed on the outer circumference of the extension portion; wherein, the second external threaded segment is threadedly connected to the second internal threaded hole.

[0069] In another embodiment, the connection between the first connector 1 and the main water supply pipe 3 can take various forms. For example, the first connector 1 can be glued or welded to the inner wall of the main water supply pipe 3 by the connecting plate 12. Alternatively, the first connector 1 can be rotated into the main water supply pipe 3 from the outside through the opening 31.

[0070] like Figures 5-8 As shown, the connecting plate 12 of the first connector 1 is fixedly connected to the inner wall of the main water supply pipe 3 by welding. Since the connecting plate 12 is welded to the inner wall of the main water supply pipe 3, and the main water supply pipe 3 is a flexible pipe body, and the main structure of the first connector 1 is located at the opening, in order to ensure that the main structure of the first connector 1 will not be severely separated from the inner wall of the main water supply pipe 3 when the main water supply pipe 3 is wound and unwound, a bending connection part 16 can be provided between the outer periphery of the first connector 1 and the connecting plate 12. The bending connection part 16 has an annular structure and an annular groove is formed in the bending connection part 16.

[0071] Specifically, the first connector 1 is generally made of plastic, thus the bent connection portion 16 has a certain elastic deformation capacity. After the connecting plate 12 is welded to the inner wall of the main water supply pipe 3, and the main water supply pipe 3 is rolled up, even if the main structure of the first connector 1 is subjected to stress, the deformation of the main structure of the first connector 1 can be buffered by the bent connection portion 16, ensuring that the connecting plate 12 and the main water supply pipe 3 maintain a good welded connection. In this way, when laying the pipe on site and connecting the second connector 2, the occurrence of the first connector 1 falling off inside the main water supply pipe 3 is reduced, thereby improving the reliability of use.

[0072] Example 2, as Figures 10-16 As shown, this application provides a flexible quick-connect fitting. The first connector 1 is inserted by rotating it into the opening 31 of the main water supply pipe 3. The following is a detailed description in conjunction with the accompanying drawings.

[0073] Flexible band quick-connect couplings include:

[0074] A first connector 1 is provided with a first through hole 11, a connecting plate 12 is provided at one end of the first connector 1, an outwardly extending insertion portion 13 is provided on the edge of the connecting plate 12, a first threaded portion is also provided on the outer periphery of the first connector 1, and the first through hole 11 also penetrates the connecting plate 12.

[0075] The second connector 2 is provided with a second through hole 21, and one end of the second through hole 21 forms a second threaded portion 211;

[0076] The second connector 2 is connected to the first connector 1 through the second threaded portion 211 and the first threaded portion, and a clamping and sealing space is formed between the second connector 2 and the connecting plate 12.

[0077] The clamping sealing space is configured to clamp the wall of the main water supply pipe.

[0078] Specifically, for the flexible quick-connect coupling, one end of the first connector 1 is provided with a connecting plate 12, and an outwardly extending insertion part 13 is provided on the edge of the connecting plate 12. The size of the insertion part 13 is smaller than the size of the opening 31 of the main water supply pipe 3, so that during on-site installation, the insertion part 13 can be easily inserted into the opening 31 for guidance. After the insertion part 13 is inserted into the opening 31, the first connector 1 is further rotated so that the connecting plate 12 rotates into the opening 31 and finally positions the connecting plate 12 inside the main water supply pipe 3 and abuts against the inner wall of the main water supply pipe 3. The second connector 2 is externally connected to the first connector 1 through a second threaded part 211, which engages with the external thread on the first connector 1 to thread the second connector 2 onto the first connector 1. After the second connector 2 is tightened onto the first connector 1, the end face of the second connector 2 opposite to the connecting plate 12 will press against the pipe wall of the main water supply pipe 3. In this way, the pipe wall of the main water supply pipe 3 located near the outer periphery of the opening 31 is squeezed between the end of the connecting plate 12 and the second connector 2, thereby achieving a sealing treatment of the opening 31 of the main water supply pipe 3.

[0079] In daily use, since the flexible quick-connect fitting can be assembled onto the main water supply pipe 3 on site, holes can be drilled directly on the main water supply pipe 3 to form an opening 31 according to the irrigation requirements of different areas. Then, the first connector 1 is guided by the insertion part 13 so that the connecting plate 12 is inserted into the main water supply pipe 3, and then sealed and fixed by the second connector 2. The irrigation branch pipe can be connected by the flexible quick-connect fitting.

[0080] Furthermore, in order to facilitate the operator to accurately and smoothly insert the insertion part 13 into the opening 31 of the main water supply pipe 3, the insertion part 13 has a pointed structure, and one side of the insertion part 13 forms an inclined surface 14.

[0081] Specifically, the insertion part 13 has a pointed structure along its outward extension direction, so that during operation, the operator can accurately insert the insertion part 13 into the opening 31 through the pointed tip of its head.

[0082] During the rotation of the first connector 1, the side of the insertion part 13 that is squeezed by the edge of the opening 31 forms an inclined surface 14. With the guidance of the inclined surface 14, the first connector 1 can rotate more smoothly during the rotation, so as to smoothly rotate the connecting plate 12 into the opening 31, thereby improving the convenience of operation.

[0083] Furthermore, the inclined surface 14 is configured to guide the insertion part 13 to be spirally inserted into the water supply pipe in a direction inclined to the centerline of the opening 31 of the main water supply pipe 3. Specifically, when the first connector 1 is connected to the opening 31 of the main water supply pipe 3, the first connector 1 is first inclined so that the insertion part 13 is inserted into the opening 31. The added inclined surface 14 can effectively guide the pipe wall around the opening 31 of the main water supply pipe 3 to slide to the upper surface of the connecting plate 12 during the tilting rotation, so as to reduce the excessive force on the edge of the opening 31 during the rotation and prevent damage. By using the rotational guidance method of a car tire on a wheel hub, the large-sized connecting plate 12 can be inserted into the small-sized opening 31, ultimately meeting the requirements of on-site drilling and installation.

[0084] Furthermore, in order to facilitate the operator to apply rotational driving force to the first connector 1, the cross-sectional shape of the first through hole is non-circular.

[0085] Specifically, the cross-section of the first through hole is non-circular, so that a tool can be inserted into the first through hole to apply external force during the rotation of the first connector 1. For example, the cross-section of the first through hole can be quincunx-shaped, triangular, or rectangular, etc.

[0086] Furthermore, the outer wall of the second connector 2 is also provided with a lever 23.

[0087] Specifically, during the tightening of the second connector 2, the operator can apply a rotational driving force to the second connector 2 using the lever 23, so that the operator can install the second connector 2 without tools.

[0088] Furthermore, in order to meet the requirements of the external irrigation branch pipe, a third internal threaded hole 212 is provided at the other end of the second through hole 21. The third internal threaded hole 212 is coaxially arranged with the second threaded part 211, and the diameter of the third internal threaded hole 212 is larger than the diameter of the second threaded part 211.

[0089] Specifically, the third internal threaded hole 212 is used to meet the connection requirements of the external irrigation branch pipe. The design of having a smaller diameter for the second threaded portion 211 compared to the third internal threaded hole 212 ensures that the second connector 2 is tightened into place during the tightening process to the first connector 1, thus guaranteeing the reliable sealing connection between the flexible quick-connect fitting and the main water supply pipe 3. For example, the multi-port pipe 4 used to connect the irrigation branch pipe is threaded into the third internal threaded hole 212.

[0090] Furthermore, in order to meet the requirements of external irrigation branch pipes, the end of the second connector 2 away from the first connector 1 is also provided with an integrally formed multi-port pipe 4.

[0091] Specifically, the second connector 2 is provided with an integrally formed multi-port pipe 4, which can meet the requirements for connection with external irrigation branch pipes.

[0092] In another embodiment of this application, based on the above embodiments one and two, an irrigation system is also provided, including a main water supply pipe 3 and multiple irrigation branch pipes (not shown). The main water supply pipe 3 is provided with multiple openings 31, and each opening 31 is provided with a flexible quick-connect fitting. The insertion part 13 of the first connector 1 of the flexible quick-connect fitting is inserted into the opening 31. The connecting plate 12 of the first connector 1 is attached to the inner wall of the main water supply pipe 3. The outer periphery of the opening 31 of the main water supply pipe 3 is clamped in the clamping and sealing space of the flexible quick-connect fitting. The irrigation branch pipes are connected to the second connector 2 of the corresponding flexible quick-connect fitting.

[0093] Furthermore, to facilitate the installation of irrigation branch pipes, the irrigation system also includes a multi-port pipe 4, which includes an installation connector 41 and at least one external connector 42. The external connector 42 communicates with the installation connector 41. The installation connector 41 is disposed in the second through hole 21 of the second connector 2, and the irrigation branch pipe is connected to the corresponding external connector 42.

[0094] Specifically, in order to reduce the number of openings 31 and meet the installation requirements of multiple irrigation branch pipes, the irrigation branch pipes to be installed on the flexible quick-connect fitting are connected by a multi-port pipe 4. During the connection process, the multi-port pipe 4 is threaded into the third internal threaded hole 212 through the mounting fitting 41, and the irrigation branch pipe can then be installed onto the corresponding external fitting 42.

[0095] To improve connection reliability, the external connector 42 and the irrigation branch pipe can be connected in a conventional quick-connect method. For example, the external connector 42 is also provided with a locking sleeve 43, the irrigation branch pipe is inserted into the external connector 42, and the irrigation branch pipe is sealed between the external connector 42 and the locking sleeve 43.

[0096] Specifically, when assembling the irrigation branch pipe, the pipe opening of the irrigation branch pipe is placed over the outside of the external connector 42 and inserted into the locking sleeve 43. Then, the locking sleeve 43 moves outward with the threaded engagement of the external connector 42 so that the end of the irrigation branch pipe is pressed between the locking sleeve 43 and the external connector 42.

[0097] Based on the above irrigation system, this application also provides a method for assembling the irrigation system, including:

[0098] The connecting plate of the first connector is attached to the inner wall of the main water pipe, and the first threaded part is aligned with the opening of the main water supply pipe; holes are drilled in the main water supply pipe 3 to form multiple openings 31. Specifically, the position of the openings 31 on the main water supply pipe 3 can be set according to the distribution of the irrigation area on site, so that the openings 31 can be as close as possible to the irrigation area, thereby shortening the overall length of the irrigation branch pipe.

[0099] The second connector is threaded onto the first threaded part via the second threaded part, and the pipe wall of the main water supply pipe is sealed and clamped between the second connector and the connecting plate.

[0100] Specifically, based on the structure of the flexible quick-connect coupling in Embodiment 1, the connecting plate of the first connector is attached to the inner wall of the active water pipe by adhesive or welding.

[0101] Based on the structure of the flexible quick-connect coupling in Embodiment 2, the first connector 1 is tilted relative to the opening 31, and the insertion part 13 is inserted into the opening 31. Then, the first connector 1 is rotated, causing the connecting plate 12 to rotate into the opening 31 and abut against the inner wall of the main water supply pipe 3. Specifically, after the opening 31, the first connector 1 is installed into the corresponding opening 31 on site. Therefore, how to conveniently install the first connector 1 is the key to determining whether the technology can be promoted. During the process of installing the first connector 1 into the opening 31, the insertion part 13 is used for guidance, and the first connector 1 is gradually rotated so that the connecting plate 12 is screwed into the opening 31, and finally the connecting plate 12 abuts against the inner wall of the main water supply pipe 3. Preferably, by providing an inclined surface 14 in the insertion part 13, during assembly, the first connector 1 is first arranged at an inclination and the insertion part 13 is inserted into the opening 31. Then, during the rotation of the first connector 1, as the connecting plate 12 gradually enters the main water supply pipe 3, the first connector 1 is also gradually flattened. Finally, the connecting plate 12 is completely inserted into the main water supply pipe 3 and abuts against the inner wall of the main water supply pipe 3.

[0102] The second connector 2 is threaded onto the first connector 1, and the pipe wall of the main water supply pipe 3 is sealed and clamped between the second connector 2 and the connecting plate 12. Specifically, after the first connector 1 is inserted into the opening 31, the second connector 2 is threaded onto the first connector 1 and the area around the opening 31 is sealed.

[0103] Finally, connect the irrigation branch pipe to the corresponding second connector 2.

[0104] By providing a connecting plate on the first connector, and an outwardly extending insertion part on the connecting plate, during use, the operator can drill a hole in the main water supply pipe at the construction site according to irrigation requirements to form an opening. Then, the insertion part of the first connector is inserted into the opening and rotated. Guided by the insertion part, the connecting plate can rotate into the main water supply pipe and abut against the inner wall of the main water supply pipe. Then, the second connector is threaded onto the first connector. At this time, the pipe wall of the main water supply pipe surrounding the opening will be sealed and clamped by the second connector. The opening is sealed between the component and the connecting plate, allowing the irrigation branch pipe to be connected to the corresponding second connector to connect with the main water supply pipe and supply water. Since the first connector can be installed on the main water supply pipe on-site, it is convenient for operators to install it on-site. Thus, according to the actual distribution needs of the irrigation area, holes can be drilled on-site at the corresponding positions of the main water supply pipe to install the flexible quick-connect coupling. This makes it convenient for operators to assemble the flexible quick-connect coupling onto the main water supply pipe on-site, improving the convenience of on-site installation and thus increasing the flexibility and convenience of use.

[0105] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
