Pressure pipeline with protection mechanism

The utility model discloses a pressure pipeline with a protection mechanism. The pressure pipeline comprises an external protection mechanism and an internal protection mechanism. The pressure pipeline protection device is simple in structure, compact in design and convenient to use, the pressure pipeline is wrapped through an overall structure formed by the upper protection cover and the lower protection cover, the whole exterior of the pressure pipeline can be isolated from the external environment, the outer wall of the pressure pipeline is prevented from being damaged, meanwhile, the pressure pipeline is supported through the supporting ring, and the pressure pipeline is prevented from being damaged. The pressure pipeline can be expanded to a certain degree in the actual use process through stretching and retracting of the damping rod, the situation that the pressure pipeline is damaged due to the fact that the pressure pipeline cannot be expanded and the internal pressure of the pressure pipeline is too
