Technical Field

[0001] This utility model belongs to the field of irrigation technology, and specifically relates to a water outlet device for irrigation of seedbeds. Background Technology

[0002] Irrigation is the act of watering the land. The principle of irrigation is that the amount, frequency, and timing of irrigation should be determined based on the water requirements of the plants, their growth stage, the climate, and the soil conditions. Irrigation should be timely, appropriate, and reasonable. Irrigation devices are required during the irrigation process, and water pipes are an indispensable part of these devices.

[0003] However, most of the irrigation pipes currently used for seedbed irrigation are fixed welded pipes, which are not only difficult to adjust the angle, but also usually connected by bolts. This structure is prone to loosening after long-term use, has poor stability, and requires tools such as wrenches for connection and repair, which is quite inconvenient. Summary of the Invention

The third connecting pipe 43 is also rotatably connected to the third pipe 3 through the second snap-fit ​​structure 6.

[0027] Specifically, the first pipe 1, the second pipe 2, and the third pipe 3 are all arranged in an "L" shape. The shape of the first pipe 1 facilitates the adjustment of the orientation angle of the three-way pipe 4, the second pipe 2, and the third pipe 3 by rotating the three-way pipe 4 around the Y-axis in the figure. The shapes of the second pipe 2 and the third pipe 3 facilitate the redirection of water flow along the X-axis in the figure to water flow along the Y-axis, so as to irrigate the seedlings to be irrigated. The outlet ends of the second pipe 2 and the third pipe 3 can be connected to sprinklers or other irrigation devices.

[0028] The three connecting pipes of the tee pipe 4 are respectively connected to the first pipe 1, the second pipe 2, and the third pipe 3 through the first snap-fit ​​structure 5 and the second snap-fit ​​structure 6.

The outer diameter of the first pipe 1 is smaller than the inner diameter of the first connecting pipe 41, and the outer diameter of the protruding rib 51 is 0.2mm-1mm larger than the inner diameter of the first connecting pipe 41.

[0031] In this embodiment, the protruding rib 51 facilitates the rotation of the tee pipe 4 relative to the first pipe 1 to achieve the purpose of adjusting the angle.

[0032] like Figures 5-6As shown, preferably, an inclined surface 52 is connected between the protruding ridge 51 and the port of the first pipe 1. The inclined surface 52 is used to make the port of the first pipe 1 have a tapered structure, so that the outer diameter of the port of the first pipe 1 is smaller than the inner diameter of the first connecting pipe 41. The outer diameter of the port of the first pipe 1 is 0.5mm-2mm smaller than the inner diameter of the first connecting pipe 41, so that the first pipe 1 can be quickly aligned with the first connecting pipe 41 for insertion into the first connecting pipe 41.

In two adjacent sets, the inclined surfaces 52 of one set are connected to the protruding ribs 51 of the other set. The arrangement of multiple sets of the protruding ribs 51 and the inclined surfaces 52 is beneficial to improving the sealing effect of the pipe connection.

The ends of the first chamfered surface 62 and the second chamfered surface 63 away from the annular ridge 61 are connected to the pipe surface. The provision of the first chamfered surface 62 and the second chamfered surface 63 makes the transition between the annular ridge 61 and the pipe surface more gradual, avoiding the annular ridge 61 from having a sharp chamfer that would damage the inner wall of the pipe.

[0040] Specifically, the annular ridge 61 and the first chamfered surface 62 and the second chamfered surface 63 are continuously arranged in three or more sets, with the three sets spaced apart. The arrangement of multiple sets of the annular ridge 61 and the first chamfered surface 62 and the second chamfered surface 63 is beneficial to improving the sealing effect of the pipe connection.

[0041] In this embodiment, the edge of the first chamfered surface 62 of the annular ridge 61 is connected to the port of the second connecting pipe 42 or the port of the third connecting pipe 43, which facilitates the quick insertion of the second connecting pipe 42 into the second pipe 2 and the quick insertion of the third connecting pipe 43 into the third pipe 3, thereby improving installation efficiency. The annular ridge 61 and the first chamfered surface 62 and the second chamfered surface 63 are continuously arranged in three or more sets, which not only strengthens the connection between the two pipes but also improves the sealing effect.

The first connecting pipe 41 is perpendicular to the second connecting pipe 42 and the third connecting pipe 43.
