Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a clamp-on buffer tube, comprising: the buffer tube comprises a buffer tube 1, wherein two ends of the buffer tube 1 are fixedly connected with inserting blocks 2, the inserting blocks 2 are inserted and combined on the surface of a joint 3, and a rubber ring 4 is arranged on the inner wall of the joint 3;

the surface of the connector 3 is sleeved with a clamping sleeve 5, and the clamping sleeve 5 is connected with a fastening bolt 6.

Referring to fig. 1, the surface of the buffer tube 1 is a corrugated tube structure, and the buffer tube 1 is arranged in the corrugated tube structure, so that the two ends of the buffer tube 1 are slightly deformed when being subjected to pressure and tension during the use of the buffer tube 1.

Referring to fig. 1 and 3, a groove is formed in the surface of the joint 3, the size of the groove is matched with the size of the outer wall of the insert block 2, the insert block 2 can be inserted into the groove by forming the groove in the surface of the joint 3, and the joint 3 is positioned and assembled between the insert block 2 and the buffer tube 1.

Referring to fig. 1 and 3, the joint between the end surface of the joint 3 and the buffer tube 1 is a welded joint, and the joint 3 is welded to the buffer tube 1 at the joint between the joint 3 and the buffer tube 1, so that the joint 3 is mounted on the buffer tube 1.

Referring to fig. 1 and 2, an annular groove is formed in the inner wall of the joint 3, the rubber ring 4 is embedded in the annular groove, the annular groove is formed in the joint 3, and the rubber ring 4 is assembled on the annular groove through the rubber ring 4, so that the rubber ring 4 is butted with a corresponding pipeline.
