[0036] In use, the pipelines to be connected are penetrated through the outer ring pipe 1, all the sealing rubber blocks 5 are driven to slide by the thrust pipe frame 2, the pipelines to be connected are compressed by the sealing rubber blocks 5, the fixing between the outer ring pipe 1 and the pipelines to be connected is realized, the concave ring 301 and the pipelines to be connected are inserted to form auxiliary installation of the rubber ring frame 3, the two thrust pipe frames 2 are connected and fixed by the threaded rod 401a to realize locking and fixing of the two thrust pipe frames 2, that is, the connection of the two sections of pipelines is completed, after the connection, the rubber ring frame 3 forms the buffering operation in the axial direction of the two sections of pipelines, the plurality of sealing rubber blocks 5 form the fixing of the circumferences of the two pipelines, and auxiliary buffering in the radial direction of the two sections of pipelines is formed, so that the damping operation of the pipeline connection is realized.

[0037] The core part of the device includes two outer ring pipes 1, which are located outside the two sections of pipelines to be connected, and the function is to surround the pipelines and provide support. The outer wall of the outer ring pipe 1 is provided with a plurality of through grooves 101, and the through grooves 101 are slidably connected with sealing rubber blocks 5.

[0038] The sealing rubber blocks 5 slide in the through grooves 101, can be in close contact with the surface of the pipeline according to the pressure change of the outer wall of the outer ring pipe 1, form the buffering and fixing of the pipeline, effectively prevent the leakage of the pipeline connection part, the rubber block 5 has a certain elasticity, can cope with the change of temperature and pressure, maintain stable sealing performance, the outer side of the outer ring pipe 1 is movably connected with the thrust pipe frame 2, when the thrust pipe frame 2 moves towards the rubber ring frame 3, the thrust pipe frame 2 drives the sealing rubber block 5 to press towards the pipeline, ensures the compression of the sealing rubber block 5 to the pipeline, and realizes the firm fixing of the connection part.

[0039] In the preferred embodiment, the inner side of the sealing rubber block 5 is provided with a groove ring 502, and the outer ring pipe 1 is provided with a through groove 101 on one side facing the groove ring 502. The through groove 101 is provided with a pushing spring 6 for pushing the sealing rubber block 5 away from the pipeline to be connected. When the pushing pipe frame 2 moves away from the sealing rubber block 5, the elastic force of the pushing spring 6 can push the sealing rubber block 5 to slide in the through groove 101, so that the inner wall of the sealing rubber block 5 is away from the pipeline to be connected, and the locking of the sealing rubber block 5 to the pipeline to be connected is released.
