Abstract

The utility model relates to a late-model brush used for cleaning the attachment or dirty rust on the solid surface. The utility model is characterized in that the ordinary elastic silk-form brush bristles are replaced by an elastic sheet-form object whose section is in flat shape. The typical mechanical characteristic of the section of the sheet-form brush bristles can make the array of each root of brush bristle have directivity; the free end surface of the brush bristle is formed by that a curved enveloping surface and a sheet surface are cross to form a cut and scrape cutting edge of a wedge angle. The utility model solves the defects when the ordinary brush is used, the brush bristles is easy fall over, and particularly, the brush bristles at four sides is very easy to be curled towards the external side.

Description

Brush

The utility model is a kind of novel brush, is used to remove the brush of solid surface-attached thing or dirty rust.

Common brush is to make bristle with wire or other filiform of standing upright, and is planted on the brush board with equidistant row and row.Such brush because the operator exerts oneself inhomogeneous or bristle is stressed too quickly, causes the bristle lodging in use easily; Especially be in that bristle on the edge is the easiest to lodge laterally, curl.Thereby the service life and the effect of brush have been influenced.

Task of the present utility model is, makes a kind of good springiness of wound, and the bristle that intensity is big is determined its arrangement mode by the cross section characteristic of bristle, makes the novel brush can powerful operation and the unlikely lodging of bristle, and the effect of the dirty rust of good removing is arranged.

To the effect that of the present utility model, bristle all is the tablet in flat cross section on each cross section axial along it; Promptly on arbitrary flat cross section of being got, has a direct-connected line of representing its long direction at least greater than the direct-connected line of other direction in addition.Its long and perpendicular to long wide ratio greater than 3.Narration for convenience, we are referred to as the cross section property direction to the long direction in cross section.Identical external force acts on the cross section property direction or vertically acts on the cross section property direction, and the easier bristle that makes of the latter produces flexural deformation.According to the various possible force directions that are subjected to of bristle, can select suitable spread pattern.Bristle is arranged in row or column on brush board.Just, according to the cross section property direction of bristle, every in every row (row) all is arranged in laterally or vertical or right bank or left bank; Or left bank and right bank are lined up zigzag respectively to make it; Or line up with above-mentioned variety of way and to mix shape.The free end of bristle is used to cut, scrapes the dirty rust of the surface of solids.At end surface, be the arc enveloping surface along the cross section property direction, this enveloping surface and intersection, bristle sheet surface; What constitute brush cuts, scrapes cutting edge, and the cutting edge angle of wedge is 70 °～110 °.

The utility model has solved bristle and has been easy to generate diastrophic problem after stressed, and the cambered surface cutting edge has guaranteed the service behaviour of brush.This novel brush has reached and can powerfully use, and removes the high purpose of dirty rust efficient.

The utility model has following accompanying drawing:

Fig. 1: be the novel brush that constitutes by the sheet bristle.

Fig. 2: be three kinds of sheet bristles and cutaway view.

Fig. 3: be several modes of pressing the cross section property direction arrangement of bristle.

The preferential scheme that adopts of the utility model is: make bristle (1) with elastic sheet metal, its cross section is a flat, is parallelogram (2) or trapezoidal (3) or flat arc (4).When an external force during in bristle ends, all can be decomposed into the component and vertical with it component that are parallel to the cross section property direction with suitable directive effect, when both equate that obviously the former is difficult for causing the flexural deformation of bristle.In view of the above, we make up bristle, arrange by its cross section property directions, line up zigzag (5), horizontal shape (6), perpendicular shape (7), mix shape (8), to adapt to the various conditions of work of brush as group.The end of bristle is an envelope round surface (9), and it and plate plane (10) intersect the angle of wedge cutting edge (11) of 70 °～110 ° of formations.

Claims

1, a kind of novel brush, bristle is planted on brush board by row or column.Feature of the present utility model is, bristle is an elastomer sheets, and promptly its each axial cross section all is the flat cross section, and its long and wide ratio is greater than 3.

2, according to the novel brush of claim 1, it is characterized in that, every bristle in every row (row), can organize by its cross section characteristic direction line up laterally, vertical, right bank, left bank, or line up zigzag by left bank and right bank group respectively, or carry out combined group row by aforementioned group of row's mode respectively.

3, according to the novel brush of claim 1 and 2, it is characterized in that the free end surface of every bristle, be the arc enveloping surface along cross section characteristic direction, this enveloping surface is to intersect with bristle sheet surface to constitute 70 °～110 ° angle of wedge cutting edge.
