[0038] A second connecting piece 2 is provided with a second through hole 21, one end of the second through hole 21 forms a first internally threaded hole 211;

[0039] The second connecting piece 2 is connected on the first connecting piece 1 through the first internally threaded hole 211 and the external thread section, and a clamping sealing space is formed between the second connecting piece 2 and the connecting plate 12.

[0040] The clamping sealing space is configured to clamp the pipe wall of the main water supply pipe.

[0041] Specifically, the soft band quick connection threaded hole joint in the application is assembled by a first connecting piece 1 and a second connecting piece 2, wherein the first connecting piece 1 and the second connecting piece 2 are matched to be able 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 piece 2 is connected with an irrigation branch pipe, so that the water flowing out of the second through hole 21 will flow into the irrigation branch pipe to the corresponding irrigation area.

[0042] For the soft band quick connection threaded hole connector, one end of the first connecting piece 1 is provided with a connecting plate 12, and an insertion part 13 extending outward is further provided at the edge of the connecting plate 12. The size of the insertion part 13 will be smaller than the size of the opening 31 of the main water supply pipe 3, so that the insertion part 13 can be easily inserted into the opening 31 during on-site installation to guide through the insertion part 13. After the insertion part 13 is inserted into the opening 31, the first connecting piece 1 is further rotated to rotate the connecting plate 12 into the opening 31 and finally make the connecting plate 12 located inside the main water supply pipe 3 and abut against the inner wall of the main water supply pipe 3. The second connecting piece 2 is threaded on the first connecting piece 1 by cooperating with the inner thread hole 211 of the first connecting piece 1 outside the main water supply pipe 3, so as to realize the threaded fixation of the second connecting piece 2 on the first connecting piece 1. After the second connecting piece 2 is tightened on the first connecting piece 1, the end face of the second connecting piece 2 opposite to the connecting plate 12 will be pressed against the wall of the main water supply pipe 3, so that the wall of the main water supply pipe 3 near the outer periphery of the opening 31 is pressed between the end of the second connecting piece 2 and the connecting plate 12, thereby realizing the sealing treatment of the opening 31 of the main water supply pipe 3.

[0043] During daily use, since the soft band quick connection threaded hole connector can be assembled on the main water supply pipe 3 on site, according to the irrigation requirements of different areas, the opening 31 can be directly punched on the main water supply pipe 3 on site, then the first connecting piece 1 is guided by the insertion part 13 to make the connecting plate 12 assembled into the main water supply pipe 3, and then the second connecting piece 2 is sealed and fixed, so that the soft band quick connection threaded hole connector can be used to connect the irrigation branch pipes.

[0044] Further, 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 is in a sharp structure, and an inclined surface 14 is formed on one side of the insertion part 13.

[0045] Specifically, the insertion part 13 is in a sharp structure along the outward extension direction thereof, so that the operator can accurately insert the insertion part 13 into the opening 31 through the sharp head of the insertion part 13 during operation.

[0046] During the rotation of the first connecting piece 1, the side of the insertion part 13 pressed by the edge of the opening 31 forms an inclined surface 14, and the inclined surface 14 is used for guiding the rotation of the first connecting piece 1, so that the first connecting piece 1 can be more smoothly rotated during the rotation to smoothly rotate the connecting plate 12 into the opening 31, thereby improving the convenience of operation.

[0047] In addition, the inclined surface 14 is configured to guide the insertion portion 13 to be inserted into the water supply pipe in a spiral manner inclined to the center line direction of the opening 31 of the main water supply pipe 3. Specifically, when the first connecting piece 1 is connected into the opening 31 of the main water supply pipe 3, the first connecting piece 1 first inserts the insertion portion 13 into the opening 31 in an inclined manner. For the increased inclined surface 14, the pipe wall around the opening 31 of the main water supply pipe 3 can be well guided to slide to the upper surface of the connecting plate 12 during the inclined rotation, so as to reduce the damage of the edge of the opening 31 due to excessive force during the rotation. By using the rotation guide mode of the tire sleeve on the hub, the large-size connecting plate 12 can be inserted into the small-size opening 31, finally meeting the requirement of on-site punching installation.

[0048] Further, in order to facilitate the operator to apply a rotating driving force to the first connecting piece 1, the cross-sectional shape of the first through hole is non-circular.

[0049] Specifically, the cross section of the first through hole is non-circular, so that during the rotation of the first connecting piece 1, a tool can be inserted into the first through hole to apply an external force. For example, the cross section of the first through hole can be plum blossom-shaped, triangular or rectangular, etc.

[0050] Further, in order to improve the sealing treatment of the opening 31, the end face of the second connecting piece 2 opposite to the connecting plate 12 is provided with at least one annular rib 22, and the annular rib 22 surrounds the outer periphery of the first through hole.

In this way, the pipe wall around the opening 31 is further pressed on the connecting plate 12 by the annular rib 22, and the annular rib 22 effectively improves the sealing performance of the opening 31.

[0052] Wherein, according to the needs, multiple annular ribs 22 can be arranged on the end face of the second connecting piece 2, and the multiple annular ribs 22 are concentrically arranged;

[0053] The space between the adjacent two annular ribs 22 is configured to form a sealing area on the pipe wall of the water supply pipe.
