Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting tools, in particular to a fire-fighting sprinkler for fire-fighting purposes. Background Art

[0002] Fire-fighting sprinklers are essential for firefighters during fire-fighting operations. By spraying high-pressure water through the fire-fighting sprinkler onto the fire point to extinguish the fire source, it is a skill that firefighters are very proficient in.

[0003] The existing fire-fighting sprinklers lack an automatic fixing and supporting device, and cannot automatically adjust the position and angle of water spraying. Most of the time, firefighters need to hold or carry the fire-fighting sprinkler. When the water pressure is unstable, it is difficult for firefighters to control the fire-fighting sprinkler, and even another firefighter is needed for assistance to complete the fire-fighting task. This not only increases the difficulty of fire-fighting for firefighters, but also increases the safety risk, bringing certain adverse effects to the using process. Therefore, we propose a fire-fighting sprinkler for fire-fighting purposes. Content of the Utility Model
