The utility model replaces the sealing ring with the sealing plug, so that the situation of the gasket offset can not occur, and the sealing stability is better; the sealing connection of the hard pipelines can be ensured only by clamping and fastening the flanges on the adjacent pipelines, and the pressing of the periphery is ensured without using excessive connecting fixing points.

Preferably, the bolt is a quick-release rod with an eccentric shaft at the end. The quick-release rod is used for replacing a common bolt, a common wrench is not needed during use, and after the eccentric shaft is rotated to a certain degree, the eccentric shaft is rotated, so that tight connection of the pipeline can be ensured.

More preferably, the eccentric shaft is fixed with a wrench, and an arc pad with an arc side is arranged between the eccentric shaft and the through hole buckle.

In a preferable structure for quickly connecting the hard pipeline, two sides of the sealing plug are truncated cone-shaped butt joints. The circular truncated cone-shaped butt joint port can be easily plugged into a pipeline to be butted, and the coaxial adjustment of the pipeline can be assisted.

More preferably, the structure of the quick connection hard pipeline, the middle part of the sealing plug protrudes to form a sealing gasket. The sealing gasket can achieve the effect of a traditional sealing ring, and can achieve a certain impact buffering effect between the flanges while increasing the sealing effect.

The structure of a further preferred quick connection stereoplasm pipeline, sealed both sides side of filling up seted up annular groove, the annular groove is internal to be settled there is the sealing washer. And a sealing ring is arranged in the annular groove, so that the sealing effect can be further enhanced.

Still further preferred is a structure for quickly connecting a hard pipeline, wherein the sealing ring is at least provided with an inner ring and an outer ring. And a plurality of rings of sealing rings are arranged, so that the sealing effect can be further enhanced.

The inner side surfaces of the nut buckle and the through hole buckle are provided with anti-skid stripes. The sliding is effectively avoided when the clamping is fixed, and the connection strength is kept.

Compared with the prior art, the utility model discloses a beneficial effect that a structure of high-speed joint stereoplasm pipeline had is: the butt joint of the utility model can be easily plugged into a pipeline to be butted, the coaxial adjustment of the pipeline can be assisted, the condition of offset placement of the gasket can not occur during installation, the sealing stability is better, the sealing gasket can achieve the effect of the traditional sealing ring, and certain impact buffering effect can be achieved between the flanges while the sealing effect is increased; the sealing connection of the hard pipelines can be ensured only by clamping and fastening the flanges on the adjacent pipelines, and the pressing of the periphery is ensured without using excessive connecting fixing points. Utilize quick detach pole to replace ordinary bolt when connecting fixedly, need not to use ordinary spanner during the use, after rotatory to certain degree, rotatory eccentric shaft can guarantee that the pipe connection is tight.
