DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] A sealing assembly for an agricultural sprinkler device, such as Figures 1 to 4 As shown, it includes a water supply pipe 1, at least two connecting pipes 2 that are movably connected in sequence, and a sealing member 3. The connecting pipe 2 is connected to the water supply pipe 1. It should be noted that in this embodiment, there are four connecting pipes 2 and the pipe diameters are reduced in sequence. It should be further noted that the number of connecting pipes 2 can be adjusted according to actual needs, and there is no specific limitation on this.

[0025] The end of the outermost connecting tube 2 is provided with a first limiting seat 4 for limiting the adjacent connecting tube 2, and the end of the inner connecting tube 2 is provided with a second limiting seat 10 for limiting the adjacent connecting tube 2 inside it. Specifically, the bottom of the connecting tube 2 inside the remaining outermost connecting tubes 2 is provided with a limiting seat 2 14, and the first limiting seat 4 corresponds to the adjacent limiting seat 2 14. The first limiting seat 4 limits the adjacent limiting seat 2 14, thereby realizing the limiting of the adjacent connecting tube 2. Specifically, when the inner connecting tube 2 extends from the adjacent connecting tube 2, the limiting seat 2 1 4 can be abutted against the lower surface of the adjacent first limiting seat 4, so as to prevent the internal connecting tube 2 from being completely separated from the adjacent connecting tube 2; the second limiting seat 10 corresponds to the adjacent limiting seat 2 14, and the second limiting seat 10 limits the adjacent limiting seat 2 14, thereby realizing the limitation of the adjacent connecting tube 2. Specifically, when the internal connecting tube 2 extends out from the adjacent connecting tube 2, the upper surface of the limiting seat 2 14 can be abutted against the lower surface of the adjacent second limiting seat 10, so as to prevent the internal connecting tube 2 from being completely separated from the adjacent connecting tube 2.

[0026] The seal 3 is used to seal between the first limit seat 4 and the adjacent connecting pipe 2. Specifically, the seal 3 is made of a deformable material, the lower surface of the seal 3 is in contact with the upper surface of the first limit seat 4, and a sealing portion 6 is provided on the seal 3. The seal 3 and the sealing portion 6 are integrally arranged, and the sealing portion 6 can be deformed to be in contact with the outer wall of the adjacent connecting pipe 2.

[0027] Specifically, the sealing portion 6 is arranged at an angle, and the sealing member 3 cooperates with the sealing portion 6 to form a stress-bearing groove 7, the notch of the stress-bearing groove 7 is connected with the gap between the first limiting seat 4 and the adjacent connecting pipe 2, and the water flow in the outermost connecting pipe 2 passes through the gap between the first limiting seat 4 and the adjacent connecting pipe 2 and acts on the stress-bearing groove 7. Under the action of water, the sealing portion 6 is deformed, so that the sealing portion 6 is in contact with the outer side wall of the adjacent connecting pipe 2. When the water flows through, the sealing member 3 is guaranteed to effectively seal the first limiting seat 4 and the adjacent connecting pipe 2.

[0028] The cross section of the stress groove 7 is trapezoidal. It should be noted that when water flows on the stress groove 7, the water flows will generate an inward force on the inclined surface of the trapezoidal cross section. This force will cause the sealing part 6 to deform, making it more closely attached to the outer wall of the adjacent connecting pipe 2.

[0029] A pressure cap 5 is provided on the outermost connecting tube 2. In the present embodiment, the pressure cap 5 is threadedly connected to the outer side wall of the outermost connecting tube 2. The pressure cap 5 is used to limit the first limiting seat 4 and the sealing member 3. A pressure ring 8 is provided between the pressure cap 5 and the sealing member 3. The pressure cap 5 has a flange portion 9. The lower surface of the flange portion 9 abuts against the upper surface of the pressure ring 8. The lower surface of the pressure ring 8 abuts against the upper surface of the sealing member 3. The pressure ring 8 is pressed against the sealing member 3 through the pressure cap 5, and then the pressure ring 8 presses the sealing member 3 against the first limiting seat 4, thereby ensuring the limitation of the sealing member 3 and thus ensuring its stability.

[0030] The inner wall of the pressure ring 8 abuts against the outer wall of the adjacent connecting pipe 2, and the cross-section of the pressure ring 8 is L-shaped. The pressure ring 8 prevents external soil impurities from invading between the pressure ring 8 and the adjacent connecting pipe 2 or between the flange 9 and the pressure ring 8.

[0031] The second limiting seat 10 is provided with a second sealing portion 11 , the cross section of which is arc-shaped. The second sealing portion 11 is made of a deformable material and can be deformed to abut against the outer side wall of the adjacent connecting pipe 2 .

[0032] It should be noted that the second limit seat 10 and the sealing part 11 cooperate to form a force-bearing groove 12, and the notch of the force-bearing groove 12 is connected to the gap between the second limit seat 10 and the adjacent connecting pipe 2. The water flow in the connecting pipe 2 passes through the gap between the second limit seat 10 and the internal adjacent connecting pipe 2 and acts on the force-bearing groove 12. Under the action of water, the sealing part 11 is deformed, so that the sealing part 11 is in contact with the outer wall of the internal adjacent connecting pipe 2. When the water flows through, the sealing part 11 is guaranteed to effectively seal the second limit seat 10 and the internal adjacent connecting pipe 2.

[0033] The cross-section of the stress-bearing groove 12 is in the shape of a step. When water flows through the gap between the second limit seat 10 and the internal adjacent connecting pipe 2 and acts on the stress-bearing groove 12, due to the structure of the trapezoidal cross-section, the water flow will generate an inward force on the inclined surface of the trapezoidal cross-section. This force will cause the sealing part 11 to deform, making it more closely attached to the outer wall of the internal adjacent connecting pipe 2.

[0034] It should be further explained that, since the sprinkler device is usually located underground under normal conditions, the external force acting on the second limit seat 10 will also cause the second sealing portion 11 to deform and make it abut against the outer wall of the adjacent internal connecting pipe 2.

[0035] The second limit seat 10 cooperates with the sealing part 2 11 to form a force-bearing groove 3 13, and the notch of the force-bearing groove 3 13 is connected to the outside. External soil impurities enter the force-bearing groove 3 13, squeezing the sealing part 2 11 to deform it, so that the sealing part 2 11 is in contact with the outer wall of the internal adjacent connecting pipe 2, ensuring that the sealing part 2 11 effectively seals the second limit seat 10 and the internal adjacent connecting pipe 2.

[0036] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
