Description

Quick assembly disassembly formula fire control pipeline interface Technical Field The utility model relates to the technical field of pipeline interface equipment, in particular to a quick detachable fire-fighting pipeline interface. Background In fire-fighting operation, the installation and disassembly efficiency of the fire-fighting pipeline interface directly influences the timeliness of fire-fighting rescue. The traditional fire-fighting pipeline connector is easy to loosen, leak water and the like in a direct splicing mode when being connected and separated, the efficiency and the reliability of fire-fighting operation are reduced, repeated operation is needed for many times in a bolt tightening mode and the like, and the requirements of the fire-fighting operation on quick response and stable water supply cannot be met. Therefore, there is a need for a fire line interface that is quick to assemble and disassemble and that is stable in connection. Disclosure of utility model The utility model aims to solve the technical problem of providing a quick-disassembly fire-fighting pipeline connector, and an operator can realize the clamping and separation of a limiting part and a second connecting pipe annular groove by only rotating a rotating block through the cooperation of structures such as the rotating block, the limiting part and the like.
