A roller brush with a retractable dark groove

Abstract

The invention discloses a rolling brush with telescopic dark grooves, including a roller brush. An inner cylinder is arranged in the roller brush in a sealing mode. The inner side of the inner cylinder is provided with an adjustment cavity. The surface of the roller brush is provided with a plurality of front-rear symmetrical dark grooves side by side vertically in the radial direction. Telescopiccoated lines are arranged in the dark grooves. A multi-stage hydraulic adjusting device is arranged in the adjustment cavity along the radial direction. The multi-stage hydraulic adjusting device isflexibly connected to the telescopic coated lines by corresponding pressing telescopic devices. Adjustment screws are fixed to the bottom left and right sides of the roller brush. The walls of the adjustment screws is sleeved by multiple stages of screw blocks in a threaded mode. The outer side ends of the adjustment screws are fixedly provided with roller frame rotating fixed blocks rotationallyconnected to a roller frame. According to the invention, the plurality of dark grooves are arranged in the surface of a traditional roller brush. The inner parts of the dark grooves are provided withthe telescopic coated lines capable of being singly adjusted for lifting. An unsmooth rolling brushing surface is formed on the roller brush. The rolling brush can be applied for fit rolling brushingof different grooves or protrusions at a painted surface.

Description

Technical field[0001]The invention relates to a roller brush, in particular to a roller brush with a telescopic dark groove.Background technique[0002]As a common brushing tool, roller brush mainly includes a roller brush barrel with a brush and a roller brush holder that is rotatably connected to the bottom surface of the left and right sides. The brush roller barrel for dipping is pushed by the roller brush holder. It is widely used in painting walls, painting panels, furniture and other fields because of its simple structure and convenient use.[0003]However, because the current roller brushes are all cylindrical, they can only paint on a flat surface. For some plates or walls with striped protrusions or grooves, roller brushes are often difficult Effectively fit the inner groove surface or raised side plate of the groove, resulting in repeated dip-dye painting at the position of the protrusion or groove, which easily leads to inconsistent paint thickness at the position of the pro...

AI Technical Summary

Problems solved by technology

[0003] However, the current roller brushes can only paint the flat surface because the cylinders of the roller brushes are all cylinder surfaces. For some plates or walls with strip-shaped protrusions or grooves, it is often difficult for the roller brush to brush. Effectively fit the inner groove surface of the groove or the raised side plate, resulting in the need for repeated dip-painting on the raised or grooved position, which can easily lead to inconsistent paint thickness on the raised or grooved position, resulting in paint The brush surface is uneven, the color is inconsistent, etc. Therefore, to solve such problems, we need an adjustable roller brush that can effectively fit the bumps or grooves according to the grooves or bumps on the brushing surface device
