Abstract

The invention provides a plugging tube for an air conditioner pipeline passing hole. The plugging tube for the air conditioner pipeline passing hole can improve the waterproof performance of the air conditioner pipeline passing hole and is suitable for walls of multiple thickness specifications. The plugging tube for the air conditioner pipeline passing hole comprises an inner tube and an outer tube. One end of the inner tube and one end of the outer tube are connected through threads. The outer wall of the other end of the inner tube is provided with an inwards recessed annular groove. An inner soft rubber ring is installed in the inwards recessed annular groove in an interference manner. The tail end of the other end of the outer pipe is provided with an annular convex shoulder with thediameter larger than that of an outer pipe body. An outer soft rubber ring is clamped on the inner side of the annular convex shoulder.

Description

technical field [0001] The invention relates to an installation device for connecting pipelines between an air conditioner internal unit and an external unit, in particular to a pipe plugging for through holes of air conditioner pipelines. Background technique [0002] At present, when the air conditioner is installed, it is necessary to reserve or open a pipe hole on the wall for the connecting pipe of the air conditioner internal unit and the external unit to pass through for the connecting pipe. And present air-conditioning installer, usually just when installing air-conditioning pipeline, a blocking cover is arranged at the opening in the wall at the pipeline via hole, and is coated with waterproof glue at the edge of blocking cover, to prevent water leakage. However, in this way of blocking the cover, since only one side sticks to the opening of the pipe through hole, the leak-proof effect is not good, and because the air-conditioning pipe needs to be bent in the indoor...
