[0019] like Figure 1-Figure 7 As shown, the present application provides a pipe connector, comprising: A first connecting member 1, wherein a first through hole 11 is provided on the first connecting member 1, a connecting plate 12 is provided at one end of the first connecting member 1, an inserting portion 13 extending outward is provided at the edge of the connecting plate 12, an external thread section is further provided at the outer circumference of the first connecting member 1, and the first through hole 11 also penetrates the connecting plate 12; A second connecting member 2, wherein a second through hole 21 is provided on the second connecting member 2, and a first internal threaded hole 211 is formed at one end of the second through hole 21; The second connecting member 2 is connected to the first connecting member 1 through the first internal thread hole 211 and the external thread section, and a clamping sealing space is formed between the second connecting member 2 and the connecting plate 12 .

[0020] The clamping sealing space is configured to clamp the pipe wall of the main water supply pipe.

[0021] Specifically, the pipe connector in the present application is assembled from a first connecting member 1 and a second connecting member 2, wherein the first connecting member 1 and the second connecting member 2 cooperate with each other 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, and the second connecting member 2 is connected to an irrigation branch pipe, so that the water flowing out of the second through hole 21 will enter the irrigation branch pipe and flow to the corresponding irrigation area.

[0022] For the pipe connector, a connecting plate 12 is provided at one end of the first connecting member 1, and an inserting portion 13 extending outward is also provided at the edge of the connecting plate 12. The size of the inserting portion 13 will be smaller than the size of the opening 31 of the main water supply pipe 3, so that the inserting portion 13 can be easily inserted into the opening 31 during on-site installation to be guided by the inserting portion 13. After the inserting portion 13 is inserted into the opening 31, the first connecting member 1 is further rotated so that the connecting plate 12 is rotated into the opening 31 and finally the connecting plate 12 is located in the main water supply pipe 3 and abuts against the inner pipe wall of the main water supply pipe 3. The second connecting member 2 is matched with the external thread on the first connecting member 1 through the first internal threaded hole 211 on the outside of the main water supply pipe 3 to achieve threaded fixing of the second connecting member 2 on the first connecting member 1. After the second connecting piece 2 is tightened onto the first connecting piece 1, the end surface of the second connecting piece 2 opposite to the connecting plate 12 will be pressed against the pipe wall of the main water supply pipe 3, so that the pipe wall of the main water supply pipe 3 located near the outer periphery of the opening 31 is squeezed between the connecting plate 12 and the end of the second connecting piece 2, thereby achieving sealing of the opening 31 of the main water supply pipe 3.

[0023] In daily use, since the pipe connector can be assembled on site to the main water supply pipe 3, it is possible to directly drill holes on site on the main water supply pipe 3 to form openings 31 according to the irrigation requirements of different areas, and then guide the first connecting piece 1 through the insertion portion 13 so that the connecting plate 12 is inserted into the main water supply pipe 3, and then seal and fix it with the second connecting piece 2, so that the irrigation branch pipe can be connected through the pipe connector.

[0024] Furthermore, in order to facilitate the operator to accurately and smoothly insert the insertion portion 13 into the opening 31 of the main water supply pipe 3, the insertion portion 13 has a pointed structure, and an inclined surface 14 is formed on one side of the insertion portion 13.

[0025] Specifically, the insertion portion 13 has a pointed structure along its outward extension direction, so that during operation, the insertion portion 13 can be accurately inserted into the opening 31 through the pointed tip of its head.

[0026] During the rotation of the first connecting member 1, the side of the insertion portion 13 squeezed by the edge of the opening 31 forms an inclined surface 14. Guided by the inclined surface 14, the first connecting member 1 can rotate more smoothly during the rotation process, so as to smoothly rotate the connecting plate 12 into the opening 31, thereby improving the convenience of operation.

[0027] In addition, the inclined surface 14 is configured to guide the insertion portion 13 to be spirally inserted into the water supply pipe in a direction inclined relative to the center line of the opening 31 of the main water supply pipe 3. Specifically, when the first connecting member 1 is connected to the opening 31 of the main water supply pipe 3, the first connecting member 1 first allows the insertion portion 13 to be inserted into the opening 31 in an inclined manner. The added inclined surface 14 can well 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 process, so as to reduce the damage caused by excessive force on the edge of the opening 31 during the rotation process. By utilizing the rotational guiding method of the automobile tire sleeve on the 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.

[0028] Furthermore, in order to facilitate the operator to apply the rotational driving force to the first connecting member 1, the cross-sectional shape of the first through hole is non-circular.

[0029] 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 connecting member 1. For example, the cross section of the first through hole can be plum blossom-shaped, triangular or rectangular.

[0030] Furthermore, in order to improve the sealing of the opening 31, at least one annular rib 22 is provided on the end surface of the second connecting member 2 opposite to the connecting plate 12, and the annular rib 22 surrounds the outer circumference of the first through hole.

[0031] Specifically, the end surface of the second connector 2 opposite to the connecting plate 12 is provided with a protruding annular rib 22. After the second connector 2 is connected to the first connector 1 and the pipe wall of the main water supply pipe 3 is clamped therebetween, the annular rib 22 will be further pressed against the outer pipe wall of the main water supply pipe 3. At the same time, the annular rib 22 is also distributed around the periphery of the opening 31. In this way, the pipe wall outside the opening 31 is further compacted against the connecting plate 12 by the annular rib 22, and the annular rib 22 effectively improves the sealing performance of the opening 31.

[0032] Wherein, multiple annular ribs 22 may be provided on the end surface of the second connecting member 2 as required, and the multiple annular ribs 22 are arranged concentrically; Two adjacent annular ribs 22 are configured to form a sealing area on the pipe wall of the water supply pipe.

[0033] Specifically, the plurality of annular ribs 22 press the pipe wall of the main water supply pipe 3 tightly against the connecting plate 12 , and a sealing area with good sealing performance is formed between two adjacent annular ribs 22 . The sealing area surrounds the opening 31 to improve the sealing performance of the periphery of the opening 31 .

[0034] Furthermore, a paddle 23 is further provided on the outer wall of the second connecting member 2 .

[0035] Specifically, during the process of tightening the second connecting member 2 , the operator can apply a rotational driving force to the second connecting member 2 through the paddle 23 , so that the operator can install the second connecting member 2 without tools.

[0036] Furthermore, in order to meet the requirements of an external irrigation branch pipe, a second internal threaded hole 212 is provided at the other end of the second through hole 21. The second internal threaded hole 212 is coaxially arranged with the first internal threaded hole 211, and the aperture of the second internal threaded hole 212 is larger than the aperture of the first internal threaded hole 211.

[0037] Specifically, the second internal threaded hole 212 is used to meet the connection requirements of the external irrigation branch pipe. The diameter of the first internal threaded hole 211 is designed to be smaller than that of the second internal threaded hole 212, so that when the second connecting member 2 is tightened to the first connecting member 1, it can be ensured that the second connecting member 2 can be tightened and assembled in place, so as to ensure the reliability of the sealed connection between the pipe connector and the main water supply pipe 3.

[0038] In another embodiment of the present application, the present application further provides an irrigation system, 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, each opening 31 is provided with a pipe connector, the insertion portion 13 of the first connecting piece 1 of the pipe connector is in the opening 31, the connecting plate 12 of the first connecting piece 1 is abutted against the inner pipe wall of the main water supply pipe 3, and the pipe wall around the opening 31 of the main water supply pipe 3 is clamped in the clamping sealing space of the pipe connector; the irrigation branch pipe is connected to the corresponding second connecting piece 2 of the pipe connector.

[0039] Furthermore, in order to facilitate the installation of irrigation branches, the irrigation system also includes a multi-way pipe 4, which includes a mounting joint 41 and at least one external joint 42, and the external joint 42 is connected to the mounting joint 41. The mounting joint 41 is arranged in the second through hole 21 of the second connecting member 2, and the irrigation branch pipe is connected to the corresponding external joint 42.

[0040] Specifically, in order to reduce the number of openings 31 and meet the installation requirements of multiple irrigation branches, the irrigation branches to be installed on the pipe connector are transitionally connected through the multi-way pipe 4. During the connection process, the multi-way pipe 4 is threadedly connected to the second internal threaded hole 212 through the installation joint 41, and the irrigation branch can be installed on the corresponding external joint 42.

[0041] In order to improve the connection reliability, the conventional pipe quick connection method can be used for the sealed connection between the external joint 42 and the irrigation branch pipe. For example, the external joint 42 is also provided with a locking sleeve 43, the irrigation branch pipe is inserted into the external joint 42, and the irrigation branch pipe is sealed and clamped between the external joint 42 and the locking sleeve 43.

[0042] Specifically, when assembling the irrigation branch pipe, the pipe mouth of the irrigation branch pipe is put on the outside of the external joint 42 and inserted into the locking sleeve 43. Then, the locking sleeve 43 and the threaded fit on the surface of the external joint 42 are moved toward the outside so that the end of the irrigation branch pipe is pressed between the locking sleeve 43 and the external joint 42.

[0043] Based on the above irrigation system, the present application also provides an assembly method of the irrigation system, including: The main water supply pipe 3 is perforated to form a plurality of openings 31. Specifically, the positions of the openings 31 on the main water supply pipe 3 can be set according to the distribution of the on-site irrigation area, so that the openings 31 can be as close to the irrigation area as possible to shorten the overall use length of the irrigation branch pipe.

[0044] The first connector 1 is inserted into the opening 31 with the insertion portion 13 tilted relative to the opening 31, and then the first connector 1 is rotated so that the connecting plate 12 rotates into the opening 31 and abuts against the inner tube wall of the main water supply pipe 3. Specifically, after the opening 31 is made, 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. In the process of installing the first connector 1 into the opening 31, the insertion portion 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 tube wall of the main water supply pipe 3. Preferably, by providing an inclined surface 14 on the insertion portion 13, during assembly, the first connecting member 1 is first arranged at an angle and the insertion portion 13 is inserted into the opening 31. Then, in the process of rotating the first connecting member 1, as the connecting plate 12 gradually enters the main water supply pipe 3, the first connecting member 1 is also gradually flattened. Finally, the connecting plate 12 completely enters the main water supply pipe 3 and rests on the inner pipe wall of the main water supply pipe 3.

[0045] The second connecting member 2 is threadedly connected to the first connecting member 1, and the pipe wall of the main water supply pipe 3 is sealed and clamped between the second connecting member 2 and the connecting plate 12. Specifically, after the first connecting member 1 is installed in the opening 31, the second connecting member 2 is threadedly tightened on the first connecting member 1 and the area around the opening 31 is sealed.

[0046] Finally, the irrigation branch pipe is connected to the corresponding second connecting piece 2 .

[0047] By providing a connecting plate on the first connecting piece and providing an inserting portion extending outward on the connecting plate, during use, the operator can drill a hole on the main water supply pipe to form an opening according to the irrigation requirements at the construction site, then insert the inserting portion of the first connecting piece into the opening and rotate it, and rely on the guidance of the inserting portion to enable the connecting plate to rotate into the main water supply pipe and abut against the inner pipe wall of the main water supply pipe, and then the second connecting piece is threadedly connected to the first connecting piece. At this time, the pipe wall of the main water supply pipe surrounding the opening will be sealed and clamped between the second connecting piece and the connecting plate to achieve sealing of the opening, and the irrigation branch pipe can be connected to the corresponding second connecting piece to achieve communication with the main water supply pipe to achieve water supply; since the first connecting piece can be installed on the main water supply pipe on site, it is convenient for the operator to install it on site. In this way, the corresponding position of the main water supply pipe can be drilled on site to install the pipe connector according to the distribution requirements of the actual irrigation area, so that the operator can assemble the pipe connector to the main water supply pipe on site to improve the convenience of on-site installation, thereby improving the flexibility and convenience of use.

[0048] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
