Technical Field

[0001] The utility model relates to the technical field of fire pipes, in particular to a fire pipe convenient for connection. Background Technique

[0002] In the built environment, fires in some special situations are likely to occur, and rescue personnel are required to carry out fire extinguishing and rescue operations. Among fire-fighting facilities, a fire truck is a special fire-fighting vehicle equipped with complete fire-extinguishing facilities, which can play a role in emergency rescue and disaster relief. A fire pipe is needed to connect with the water supply tank on the fire truck to provide sufficient water source for water spraying fire extinguishing work.

[0003] The authorized announcement number is CN220268709U, which discloses a fire pipe connection device convenient for plugging. Through the setting of a docking mechanism and a locking mechanism, the connecting pipe joint and the water outlet pipe joint are docked. The plugging ring is inserted into the plugging groove, and the connecting pipe joint is rotated to make two positioning columns inserted into two positioning holes to quickly complete positioning. Then, by respectively holding two rocker arms and rotating the turntable, the corresponding threaded rod is driven to rotate. One end of the threaded rod is threadedly connected into a corresponding group of threaded holes two and threaded holes three, so as to firmly lock the connecting pipe joint and the water outlet pipe joint together, and the connecting pipe joint can no longer be rotated, realizing the quick installation and docking of the connecting pipe joint and the water outlet pipe joint, with relatively stable connection and not easy to fall off, and the disconnection is also very convenient.
