Description

Technical Field

[0001] The utility model relates to the technical field of roller brushes, in particular to a retractable roller brush for construction engineering. Background Art

[0002] Roller brushes are often used in construction projects. There are three types of roller brushes: long hair, medium hair, and short hair. The length of the roller brush hair is the length, not the thickness and length of the roller itself. The hair is usually divided into wool and chemical fiber. Roller brushes are mostly made of wool and foam plastics. They can be divided into paint roller brushes, napped roller brushes, floor paint roller brushes, flat coating roller brushes, etc. They are mainly used for large-area paint rolling in construction decoration projects.

[0003] When using a roller brush for painting, in order to adapt to different painting heights, the mounting frame of the roller brush can generally be retracted to change the painting coverage of the roller brush. However, in some painting environments, there will be outward convexities and inward concave painting surfaces. However, the existing retractable roller brushes for construction projects are not convenient for changing the angle of the roller brush. Therefore, a retractable roller brush for construction projects is proposed. Utility Model Content
