Problems solved by technology
[0002] Painting the inner wall of the pipe is a very labor-intensive and time-consuming work. For pipes with small diameters, the "relative weight is relatively light." The paint is done by people entering the pipeline. It is impossible to enter the pipeline between 10 cm and 35 cm. Because it is heavy and it is difficult to use the pouring method to completely cover the paint, it must be carried out with the help of a spreader. Painting operation, very labor-intensive

A special paint brush for the inner wall of a pipeline, which relates to a brush for pipelines. One end of a cylinder body (3) is a closed structure, and a plastic strip breathing piece (13) is arranged on one side of the cylinder body. The outer edge surface of the cylinder body The bristles (4) are evenly distributed, and the other end of the barrel is fixedly connected to one end of the sleeve (22), and the other end of the sleeve is connected to a reduced-diameter connecting pipe (24), and an elliptical piston block ( 16), one end of the elliptical hole is provided with a limit mechanism, and one end of the rod body (18) passes through the round hole (34) of the elliptical plate (35) at the other end of the elliptical hole to connect to the elliptical piston block, and the rocker (27) at the other end of the rod body ) outer end is provided with rocking handle (28); The present invention utilizes the bristle of rocking handle to drive cylinder to brush paint on pipeline inwall, drives ellipse piston block by bar body and makes the plastic elongated breathing piece of cylinder replenish paint in pipeline.
Description
【Technical field】 [0001] The present invention relates to a pipeline brush, in particular to a special paint brush for the inner wall of a pipeline. 【Background technique】 [0002] The painting operation of the inner wall of the pipeline is a very labor-intensive and time-consuming work. For the pipeline with a smaller diameter, the "relative weight is also lighter", the filling method is used to make the inner wall of the pipeline full of paint, and the inner wall of the larger diameter is painted. The paint is done by people entering the pipeline. It is impossible to enter the pipeline between 10 cm and 35 cm. Because it is heavy and difficult to use the pouring method to fully cover the pipeline, it must be painted with a spreader. Painting work is very labor-intensive. [Content of the invention] [0003] In order to overcome the deficiencies in the background technology, the present invention discloses a special paint brush for the inner wall of the pipeline, which us...
