[0016] Reference Figures 1 to 3It can be seen that: a pipeline sealing connection structure includes pipeline 1, pipeline 2, limiting column 13, sealing ring 14, limiting column 25, sealing ring 26, sealing sleeve 7, limiting groove 18, anti-rotation boss 9 and limiting groove 210, one end of the pipeline 1 is symmetrically fixedly connected with two limiting columns 3, the pipeline 1 is located on the outer side of the limiting column 3 and is installed with a sealing ring 4 through the sealing groove, the pipeline 22 is symmetrically fixedly connected with the limiting column 25, the outer side of the pipeline 22 close to the pipeline 1 is installed with a sealing ring 26 through the sealing groove, and the sealing sleeve 7 is sleeved Installed on the outside of one end of pipeline 1 and pipeline 2, the sealing sleeve 7 has two limit grooves 8 evenly arranged on the upper and lower ends near the pipeline 1, and one end of the two limit grooves 8 is respectively integrated with anti-rotation bosses 9, and the sealing sleeve 7 has two limit grooves 10 evenly arranged on the upper and lower ends near the pipeline 22, and one end of the two limit grooves 2 10 is respectively integrated with anti-rotation bosses 9, and the anti-rotation bosses 9 can respectively clamp the limit column 1 3 and the limit column 2 5 in the limit groove 1 8 and the limit groove 2 10, so as to lock the positions of pipeline 1 and pipeline 2 2 in the sealing sleeve 7.

[0017] The pipeline 1 and the pipeline 2 are respectively slidably matched with the sealing sleeve 7, which is convenient for the installation and disassembly of the pipeline 1 and the pipeline 2; the two limit posts 1 are respectively slidably matched with the two limit grooves 18, and the two limit posts 2 are respectively slidably matched with the two limit grooves 2 10. This design is convenient for the installation and disassembly of the pipeline 1 and the pipeline 2, and is also convenient for locking the two pipelines in the sealing sleeve 7 through the limit posts and the limit grooves; the sealing ring 1 and the sealing ring 2 are respectively located in the sealing sleeve 7 and are sealed with the sealing sleeve 7. The sealing ring 1 and the sealing ring 2 are made of rubber material. The rubber material is elastic and can generate extrusion force between the sealing sleeve 7, which can ensure good sealing performance. At the same time, it can also prevent the sealing sleeve 7 from moving and rotating when there is no external force on the two pipelines.

[0018] The principle and advantages of the utility model are as follows: a pipeline sealing connection structure, when installing, firstly, the sealing ring 14 and the sealing ring 26 are respectively sleeved in the sealing grooves of the pipeline 1 and the pipeline 22, and then the end of the pipeline 1 with the sealing ring 14 is inserted into the end of the sealing sleeve 7 with the limiting groove 18, and the limiting column 13 is allowed to enter the bottom end of the limiting groove 18, and then the end of the pipeline 2 with the sealing ring 26 is inserted into the sealing sleeve 7, and the limiting column 25 is entered into the limiting groove 210, when the limiting column 25 is aligned with the opening of the anti-rotation boss 9 on the limiting groove 210, the insertion of the pipeline 22 is stopped, and then the sealing sleeve 7 is rotated to allow the limiting column 13 and the limiting column 25 to be stuck in the opening on one side of the anti-rotation boss 9 until The sealing sleeve 7 is fixed and will not rotate any more. The sealing ring 1 4 and the sealing ring 2 6 are made of rubber material and are in sealing cooperation with the sealing sleeve 7. Therefore, a certain external force is required when pulling the pipeline 1 1 and the pipeline 2 2 and rotating the sealing sleeve 7. Therefore, in the absence of a certain external force, the limiting column 1 3 and the limiting column 2 5 will be locked in the groove on one side of the anti-rotation boss 9, and the pipeline 1 1 and the pipeline 2 2 will not move in the sealing sleeve 7. The utility model has a simple and reasonable structure, is easy to install and disassemble, has good sealing performance, and has a low manufacturing cost, and is suitable for popularization and use.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
