Description

Technical Field

[0001] This utility model relates to the field of building decoration, and in particular to an adjustable paint roller. Background Technology

[0002] In the process of building decoration, paint needs to be applied to buildings. The methods of applying architectural paint are generally divided into brushing, rolling, spraying, and scraping. These methods are highly operable and do not result in missed areas or drips. Rolling: Paint is applied to walls or other building surfaces using a roller. This method is fast and efficient, but it is prone to uneven paint thickness and bubbles. Spraying: Paint is applied to walls or other building surfaces using a spray gun. This method is the fastest and most even, covering even small areas. However, spraying requires specialized skills and equipment and is more expensive. Scraping: Paint is applied to walls or other building surfaces using a scraper. This method is suitable for some special wall textures, but it is more cumbersome and requires specialized skills.

[0003] Currently, many building complexes use a combination of roller coating and spraying. However, during the coating application process, spraying is ineffective for corners and crevices due to the long distance required, resulting in incomplete coverage and environmental unfriendliness. Roller coating, on the other hand, requires frequent brush changes, necessitates carrying more tools, and hinders faster construction. Summary of the Invention

Two adjacent intermediate roller brush units are connected by threads through the threaded ring and the concave annular groove.

[0008] As a further improvement of this utility model, the left sealing roller brush unit and the right sealing roller brush unit are symmetrically installed. The left sealing roller brush unit includes an L-shaped rotating shaft, a sealing cover and a storage sleeve II. One end of the L-shaped rotating shaft is rotatably installed at the center of the sealing cover. One end of the storage sleeve II is fixedly installed on one side of the sealing cover. A concave annular groove II is provided on the circular end face of the other end of the storage sleeve II. An internal thread is provided on the inner wall of the concave annular groove II.
