Abstract

The application relates to a pipe body airtightness detection connecting device and relates to the technical field of a pipe body airtightness detection device, which comprises two standard quick connectors, a self-adapting sealing clamp structure comprises a plurality of sealing shells, the outer portions of the plurality of sealing shells are slidably connected to the outer portions of the standard quick connectors, the two ends of the plurality of sealing shells are fixedly connected with connecting blocks, and the inner portions of the two connecting blocks are slidably connected with limiting bolts. The self-adapting sealing clamp structure can adapt to an oval pipe and other special-shaped pipe bodies through the soft material of the sealing shells, and the sealing shells are connected and limited by the connecting blocks and the limiting bolts fixed at the two ends of the sealing shells, so that the self-adapting sealing clamp structure also has a certain sealing effect on the standard quick connectors between the self-adapting sealing clamp structures.
