Problems solved by technology

[0006] However, retaining rails configured in the form of open circles or arcs according to the prior art have the disadvantage that the diameter of the retaining rail has large tolerances due to the manufacturing process, which significantly reduces the accuracy of the fit of the retaining rail in the groove of the dust cover. deterioration

Embodiment Construction

[0042] Angle grinder dust cover 100 according to the present invention is in figure 1 is shown in top view.

[0043] The angle grinder dust cover 100 has a cover body 10 for covering a round grinding wheel, not shown in the figures. The axis of rotation R of the grinding wheel is indicated by a dotted line. The angle grinder dust cover 100 likewise has a cover section 20 which is displaceable along the cover body 10 in the circumferential direction N of the cover body 10 .

[0044] The cover body 10 forms the main part for covering the grinding wheel, wherein a movable cover section 20 is provided for covering and releasing the remaining part of the grinding wheel.

[0045] as in figure 2 , 3 , 4 and 5, both the hood body 10 and the movable hood segment 20 each have a sealing element 30 in the form of a wiper screen. As will be explained in more detail below, the sealing element 30 is positioned in the first holding rail 31 and in the second holding rail 31 ′.

Abstract

A dust collector for an angle grinder comprises a collector body for covering a circular grinding disk, a sealing element for sealing at least some sections of the collector body from a surface to bemachined by the grinding disk, at least some sections of the sealing element being placeable in a first and a second retaining rail, and a suction terminal via which the abraded surface particles canbe sucked off the collector body. The first retaining rail extends along a closed periphery of the collector body, and in the collector body, the sealing element is spring-mounted by at least one spring element in the axial direction relative to the axis of rotation of the grinding disk.

Description

technical field [0001] The invention relates to a dust cover for an angle grinder, comprising: a cover body for covering a round grinding wheel; a sealing element which can be positioned at least partially in a first holding track and a second holding track for closing the cover body an at least partial sealing against the surface to be machined by means of the grinding wheel; and a suction connection via which surface wear products can be sucked out of the housing. The sealing element can be, for example, a brush screen, a sheet or the like. Background technique [0002] Angle grinder boots of the type mentioned at the outset are known in principle from the prior art. It serves to prevent the spread of dust during the grinding process in order to protect the health of the user of the angle grinder. [0003] It is known to equip the hood with sealing elements, for example a surrounding brush curtain or a plurality of brushes, so that the hood is closed on the surface to be...
