Description

Technical Field

[0001] The utility model belongs to the field of fire reel racks, and in particular relates to a fire reel rack. Background Art

[0002] The full name of the fire hose reel is "fire hose reel". It is composed of valves, input pipelines, hoses, spray guns, etc., and can spray fire extinguishing agents in the process of quickly unfolding the hose. Fire hoses should be installed in luxury hotels, important office buildings, commercial buildings of Class I buildings, exhibition buildings, comprehensive buildings, and other high-rise buildings with a building height of more than 100m. Hose reels are divided into water, dry powder, and foam hose reels according to the fire extinguishing agents they transport, and are divided into fire truck and non-fire truck hose reels according to their use occasions. At present, traditional fire hose reels have a single structure and need to be manually reeled, which is time-consuming and labor-intensive and cannot meet the needs of use.
