Round brush
Technical field
This practicality invention relates to a kind of painting tool, particularly relates to a kind of round brush.
Background technology
At present, the round brush of the practical prior art of people is generally brush holder support and is socketed on cylinder, and bristle is attached to the outer surface of cylinder, and brush holder support and cylinder are fixed by nut screw rod.Need round brush to be stained with some liquid during this round brush brushing liquid, be then brushed to required place and go, because the liquid that bristle is stained with is limited, go again to be stained with liquid in container so brush a few times, such inconvenient operation, affects painting efficiency.When cylinder changed by needs, unscrew the screw thread of resting barrel and round brush, be inconvenient to like this change cylinder, troublesome poeration.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of painting efficiency high, be convenient for changing the round brush of cylinder.
The present invention for the adopted technical scheme that solves the problem is: a kind of round brush, it comprises brush holder support and is socketed in rotating sleeve pipe on brush holder support, sleeve pipe is provided with bristle, described brush holder support shape is the horizontal straight-bar of length be connected as a single entity, perpendicular to growing horizontal straight-bar and the vertical quarter butt rolled over from long horizontal straight-bar one end, oblique straight-bar with vertical quarter butt infolding and in obtuse angle, roll over under oblique straight-bar and the vertical bar of the length vertical with horizontal straight-bar, it is characterized in that, the left end of the horizontal straight-bar of length of described brush holder support is through left cover, the passage for coating circulation is provided with in brush holder support, the brush holder support corresponding with sleeve position is provided with multiple discharging opening, described sleeve pipe is provided with the hole of multiple through tube wall, described brush holder support lower end is provided with the joint be connected with automatic feed pipeline, described round brush also comprises gag lever post and is fixed on the bearing on brush holder support, described gag lever post is actively socketed in sleeve pipe through right cover, described gag lever post shape is the short horizontal straight-bar be connected as a single entity, perpendicular to short horizontal straight-bar and the vertical quarter butt rolled over from short horizontal straight-bar one end, oblique straight-bar with vertical quarter butt infolding and in obtuse angle, the button handle rectangular with oblique straight-bar, described oblique straight-bar and button handle are hinged on bearing, one end of Compress Spring is supported on bearing, one end is supported on button handle in addition, under the compressing of gag lever post, make left cover and right cover press two ends in sleeve pipe.
As preferably, the rubber ring be provided with in described left cover and right cover and between sleeve pipe, can prevent liquid from flowing out from lid like this, cause waste.
As preferably, described multiple holes are evenly distributed on the excircle of cylinder, makes liquid more even when brushing like this.
As preferably, described brush holder support outside is provided with handle sleeve, such increasing friction force, round brush of conveniently holding steadily.
