[0020] Please refer to Figures 1-3, embodiments provided by the present utility model: A sealing structure for an air-conditioning pipeline connection joint, including pipeline one 1 and pipeline two 4. One end of pipeline one 1 is inserted into the interior of pipeline two 4. Two clamping grooves two 10 are equidistantly opened at the surface position of pipeline one 1. Sealing rings two 11 are respectively clamped inside the clamping grooves two 10. The sealing rings two 11 are made of rubber and are circular rings. The sealing rings two 11 have elasticity, improving the sealing performance when pipeline one 1 is inserted into pipeline two 4. An installation seat one 2 is sleeved on the outer surface of pipeline one 1 by welding. A clamping groove one 8 is opened on the side wall of installation seat one 2 close to the clamping groove two 10. The internal dimension of the clamping groove one 8 is adapted to the external dimension of pipeline two 4. A sealing ring one 9 is clamped inside the clamping groove one 8. The cross-section of the sealing ring one 9 is U-shaped. The sealing ring one 9 can be sleeved on the end of pipeline two 4, thereby improving the sealing performance when pipeline two 4 is inserted into the clamping groove one 8, and thus improving the sealing performance of the connection between pipeline one 1 and pipeline two 4. A support rod 12 is fixedly welded on the side wall of installation seat one 2 close to pipeline two 4. A steel ball 13 is fixedly welded at the end of the support rod 12. The steel ball 13 is spherical and has a smooth surface. An installation seat two 3 is sleeved on the outer surface of pipeline two 4 by welding. A notch one 5 is opened on the side wall of installation seat two 3. A sliding groove one 14 for the support rod 12 to be inserted is opened on the surface of installation seat two 3 close to the notch one 5. The sliding groove one 14 is in a 180-degree arc shape. The width of the sliding groove one 14 is adapted to the diameter of the support rod 12. A sliding groove two 15 for the steel ball 13 to slide is opened at the inner bottom end of the sliding groove one 14. Both the installation seat one 2 and the installation seat two 3 are cylindrical. The external dimensions of the installation seat one 2 and the installation seat two 3 are adapted to each other, improving the convenience of inserting and positioning the support rod 12 and the steel ball 13. The internal dimension of the sliding groove two 15 is adapted to the external dimension of the steel ball 13. The sliding groove two 15 is sequentially connected to the notch one 5 and the sliding groove one 14. The operator sleeved pipeline two 4 on the outer surface of pipeline one 1, then inserted the steel ball 13 from the top of the notch one 5 into the interior of the sliding groove two 15, and then rotated the whole installation seat one 2 clockwise by 180 degrees, thereby realizing the sealed connection between pipeline one 1 and pipeline two 4.

[0021] A slot 27 is provided at the surface position of the mounting seat 2 away from the support rod 12, and the slot 27 runs through the side wall of the mounting seat 2. The interior of the slot 15 is rotatably connected to the limit block 6 through a torsion spring. The outer size of the limit block 6 is adapted to the inner size of the slot 15 and the limit block 6. A protrusion 16 is fixedly provided at the bottom end of the limit block 6. The protrusion 16 is hemispherical and adapted to the inner size of the slide groove 2 15, which improves the stability of the connection between the mounting seat 1 2 and the mounting seat 2 3. A paddle 17 is fixedly provided at the top of the limit block 6. The paddle 17 is fixedly connected to the limit block 6 and the protrusion 16 to form an integrated structure, which improves the convenience of rotation of the limit block 6. After the mounting seat 1 is rotated 180 degrees clockwise, the slot 15 and the slot 2 7 can be connected. When the limit block 6 is clamped into the interior of the slot 2 7 under the action of the torsion spring elastic force, the relative rotation of the mounting seat 1 2 and the mounting seat 2 3 can be limited, thereby improving the stability of the connection between the pipeline 1 and the pipeline 2 4.

[0022] Working principle: When the sealing structure of the air-conditioning pipe connection joint is used, the operator first turns the paddle 17 to rotate the limit block 6 to expose the slot 15, and the slot 15 is connected with the slide 2 15 and the slide 14 in turn. The operator sets the pipe 2 4 on the outer surface of the pipe 1, and inserts the steel ball 13 from the slot 15 into the slide 2 15, so that the side walls of the mounting seat 12 and the mounting seat 2 3 fit together. The operator rotates the mounting seat 12 clockwise by 100 degrees to make the slide 2 15 clamped on the other end of the slide 2 15, thereby realizing the sealed connection between the pipe 1 and the pipe 2 4. The sealing ring 11 is elastic, which improves the sealing performance of the pipeline 1 when it is inserted into the pipeline 2 4. The cross-section of the sealing ring 9 is U-shaped, and the sealing ring 9 can be sleeved on the end of the pipeline 2 4, thereby improving the sealing performance of the pipeline 2 4 when it is inserted into the slot 8, thereby improving the sealing performance of the connection between the pipeline 1 and the pipeline 2 4. When the slot 1 5 and the slot 2 7 are connected, when the operator releases the paddle 17, the limit block 6 and the protrusion 16 are successively engaged in the slot 2 7 and the slide groove 2 15, the limit block 6 can limit the mounting seat 1 2 and the mounting seat 2 3 from rotating towards each other, thereby improving the stability of the connection between the pipeline 1 and the pipeline 2 4.
