Flexible sealed firefighting connection device and using method thereof

The invention relates to the field of firefighting equipment, in particular to a flexible sealed firefighting connection device used for connecting a fire hose and a firefighting device, and a using method thereof. The flexible sealed firefighting connection device comprises a flexible connecting part and silica gel belts. One end of the flexible connecting part is a tight opening end, and the other end of the flexible connecting part is a loose opening end. The fire hose is sleeved with the tight opening end, and the firefighting device is sleeved with the loose opening end. A connector of the fire hose and a connector of the firefighting device are both located in the flexible connecting part. One silica gel belt is arranged between the tight opening end of the flexible connecting part and the tubular wall of the fire hose. The other silica gel belt is located on the outer side of the loose opening end of the flexible connecting part. Fixing belts for binding are both arranged at the tight opening end and the loose opening end of the flexible connecting part and provided with gluing buckles. The loose opening end of the flexible connecting part is fixed to the neck of the lower end of the connector of the firefighting device through the corresponding fixing belt and the corresponding silica gel belt or is directly fixed to the connector of the firefighting device. The flexible sealed firefighting connection device effectively avoids the influence of emergency situations, and the fire hose and the firefighting device can communicate in time.
