Paint brush special for pipeline inner walls

Abstract

A special paint brush for the inner wall of a pipeline relates to a brush for a pipeline, and is characterized in that one end of a barrel (3) is of a closed structure, a plastic strip breathing sheet(13) is arranged on one side of the barrel, bristles (4) are uniformly distributed on the outer edge surface of the barrel, and the other end of the barrel is fixedly connected with one end of a sleeve (22); the other end of the sleeve (22) is connected to a necked connecting pipe; an oval piston block (16) is arranged in an oval hole (33) in the connecting pipe, a limiting mechanism is arrangedat one end of the oval hole, one end of a rod body (18) penetrates through a round hole (34) of an end oval plate (35) at the other end of the oval hole and then is connected with the oval piston block, and a rocking handle (28) is arranged at the outer end of a rocking rod (27) at the other end. According to the invention, bristles of the barrel are driven by the rocking handle to brush paint onthe inner wall of a pipeline, and the oval piston block is driven by the rod body to enable the plastic long-strip breathing piece of the barrel to supplement paint into the pipeline.

Description

【Technical field】 [0001] The invention relates to a brush for pipelines, in particular to a special paint brush for the inner wall of pipelines. 【Background technique】 [0002] Painting the inner wall of the pipe is a very labor-intensive and time-consuming work. For the pipe with a small diameter, 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. The painting operation is very time-consuming. 【Content of 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 uses the handle to drive the bristles of the cylinder to paint the inner wall of the pipeline, and the rod body drives the elliptical pi...
