A tool for painting walls

Abstract

The invention provides a tool for wall painting, and relates to the field of decorating tools. The tool for wall painting is exquisite in structure, easy and convenient to operate and good in sealing effect, and the material utilization rate can be increased through automatic control over a piston. The tool for wall painting comprises a handrail, a roller and a connecting assembly. The roller is connected to one side of the handrail through the connecting assembly and is perpendicular to the handrail. The handrail comprises an inner rod body, an outer sleeve body, the piston, a sealing pad, a connecting rod, a suction nozzle and a spray head, wherein the inner rod body is hollow, and one end of the inner rod body is connected with the connecting assembly. When the tool for wall painting is in use, an operator can place the suction nozzle into a paint barrel firstly and pull the outer sleeve body outwards at the same time, so that paint is sucked into the inner rod body; and then the inner rod body or the outer sleeve body is repeatedly waved on a wall in the same direction, so that the paint is sprayed out automatically, and the wall is painted rapidly. By adoption of the tool for wall painting, the utilization rate of the paint is effectively increased, and environmental pollution during construction is reduced.

Description

technical field [0001] The invention relates to the field of decoration tools, in particular to the improvement of the tools used for wall painting. Background technique [0002] At present, people mostly use a wall brusher composed of a roller and a thin shaft to paint the wall surface, which needs to be repeatedly dipped in materials during use, which is very troublesome to operate. In response to this, the National Bureau published a Chinese invention patent application titled "An Improved Wall Cleaner" with the application number "201410270328.5" on February 3, 2016. In this case, a piston was set in the handle. Thus, the construction efficiency is greatly improved. [0003] However, people find after actual use that such technical solutions still have the following problems: one, the length of the handle is long, which is extremely inconvenient for the operation of the piston; two, the piston is only sealed by a sealing ring on one side, and the air tightness is relati...

Problems solved by technology

[0003] However, people find after actual use that such technical solutions still have the following problems: one, the length of the handle is long, which is extremely inconvenient for the operation of the piston; two, the piston is only sealed by a sealing ring on one side, and the air tightness is relatively high Poor, which has a certain impact on the absorption of paint; 3. When using this type of technical solution, it is necessary to control the handle with one hand to make the roller paint the wall, and control the piston with the other hand to spray the paint outward, so the operation is difficult. Construction personnel The labor intensity is high and it is difficult to effectively control the displacement of the piston
