The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 2: the present invention includes support 1, handle 2, locating piece 3, cover plate 4, base plate 5, slide block 6, screw rod 7, embossing handle 8, pivot pin 9, clamp nut 10, bearing pin 11, installing hole 12, screw 13, link slot 14, locating slot 15, bolt 16, positioning base 17, the first connecting plate 18 and the second connecting plate 19.
As illustrated in fig. 1 and 2: described positioning base 17 comprises base plate 5, and described base plate 5 is the L-type structure; Base plate 5 is provided with locating piece 3, and described locating piece 3 fixes by screw 13 with base plate 5; Also be provided with cover plate 4 on base plate 5,3 formation locating slots 15 of described cover plate 4 and locating piece; Described locating slot 15 is along the distribution of lengths of positioning base 17.Be provided with screw rod 7 in described locating slot 15, after an end of described screw rod 7 passes base plate 5, and stretch in locating slot 15.Screw rod 7 is fastened and connected by two clamp nuts 10 and base plate 5.Screw rod 7 is provided with slide block 6 corresponding to the end of stretching in locating slot 15, and described slide block 6 fixes with screw rod 7, and screw rod 7 can be with movable slider 6 in the interior slip of locating slot 15; Screw rod 7 is provided with embossing handle 8 corresponding to the other end that is connected with slide block 6.
Slide block 6 is concaved with link slot 14 corresponding to the other end that is connected with screw rod 7, is provided with handle 2 in described link slot 14; Link slot 14 is complementary with handle 2.One end of handle 2 passes link slot 14, and handle 2 is provided with support 1 corresponding to the end that passes link slot 14; Handle 2 distributes along the length direction perpendicular to slide block 6.Described support 1 comprises the first connecting plate 18 and the second connecting plate 19, and described the second connecting plate 19 is in tilted layout in the end of the first connecting plate 18, and the angle between the second connecting plate 19 and the first connecting plate 18 axis is the obtuse angle; The second connecting plate 19 fixes by bearing pin 11 and handle 2 corresponding to the other end that is connected with the first connecting plate 18.Described the first connecting plate 18 is provided with installing hole 12, and described installing hole 12 is corresponding with the regulating wheel installation shaft on rolling disc.The first connecting plate 18 is articulated on rolling disc by pivot pin 9, thereby when moving handle 2, can the abrasive band on regulating wheel be positioned.
As depicted in figs. 1 and 2: during use, positioning base 17 is fixedly installed on rolling disc by bolt 16, and the first connecting plate 18 of support 1 is articulated on rolling disc by pivot pin 9; The regulating wheel installation shaft is arranged on the first connecting plate 18 by installing hole 12, and regulating wheel is provided with the abrasive band.During work, when rust remover eliminates rust to different steel wires, carry out corresponding matching in order to make abrasive band and steel wire, must adjust contacting of abrasive band and steel wire.When adjusting the location, adjust the position of slide block 6 by screw rod 7, after slide block 6 was adjusted, screw rod 7 was fastened and connected by clamp nut 10 and positioning base 17; Then moving handle 2, and handle 2 is moved relative to slide block 6.Handle 2 and the second connecting plate 19 are fixedly connected, and due to the second connecting plate 19 and the first connecting plate 18 tilt distribution, the first connecting plate 18 is hinged with rolling disc simultaneously; When thereby handle 2 moves, can make regulating wheel relatively rotate dish mobile, thereby adjust the rate of tension in abrasive band on regulating wheel, can carry out effective location to the abrasive band.
Positioning base 17 of the present invention is fixedly installed on rolling disc by bolt 16, and support 1 is hinged by pivot pin 9 and rolling disc; Be provided with slide block 6 in positioning base 17, screw rod 7 can be with movable slider 6 in the interior slip of positioning base 17; Slide block 6 is provided with handle 2; By installing hole 12, regulating wheel is installed on support 1, described regulating wheel is provided with the abrasive band, and when slide block 6 moved, support 1 can drive regulating wheel and relatively rotate the dish movement when handle 2, thereby can adjust the rate of tension in abrasive band, applicable corresponding steel wire; Simple in structure, easy to install, improved operating efficiency, safe and reliable.
