Description
Technical Field

[0002] Fire-fighting pipes refer to pipe materials used in firefighting to connect fire-fighting equipment and instruments and to transport water, gas or other media for fire-fighting. When installing fire-fighting pipes, they are positioned and fixed with fixing devices. After the fire-fighting pipes are installed, due to the high water pressure in the fire-fighting pipes and the large pressure fluctuations when in use and not in use, the fire-fighting pipes are easily vibrated by water hammer. However, the existing fire-fighting pipe fixing devices are mostly rigid bracket structures. When the fire-fighting pipes vibrate, they cannot absorb the vibration force and have poor anti-seismic effect, which will lead to looseness between the fire-fighting pipes and the fixing devices. In the long run, the fire-fighting pipes will be easily damaged or loosened, and in severe cases, the pipes will leak. Therefore, there is a need for a fire-fighting pipe fixing device that is convenient for buffering and shock-absorbing the fire-fighting pipes. Utility Model Content
