[0002] The fire hose anti-twisting structure can effectively reduce the delay caused by twisting, tangling and other problems during the use of the hose. In emergency rescue scenarios, every second is crucial. By preventing the hose from twisting, firefighters can lay the hose more quickly and effectively, thereby carrying out firefighting or rescue work faster and improving rescue efficiency.

[0003] After searching, the utility model with the announcement number CN220360662U discloses a fire hose anti-twisting structure. Although the utility model patent solves the problem that the fire hose is prone to twisting, folding, and jamming due to the lack of a guide limit structure on the winding frame, thereby reducing the winding and reeling efficiency;

[0004] First, the structure and principle of the utility model are relatively complex, which is not conducive to the daily inspection and maintenance of the device. In addition, the utility model is only effective for slightly twisted fire hoses, and has little effect on fire hoses with large angles;

[0005] Second, the utility model lacks the function of cleaning the stains on the fire hose. When the stains accumulate and are not cleaned for a long time, the nozzle may be blocked, which directly affects the water spraying effect of the fire hose and reduces its efficiency in the fire extinguishing process. When the stains contact the fire hose for a long time, it may corrode the hose material and shorten its service life.

[0006] Therefore, a fire hose anti-twisting structure is proposed. Utility Model Content
