Abstract
The utility model relates to a dust-proof cover for a percussion electric drill, which is suitable for being matched when a percussion electric drill is drilled on wall or aluminum alloy, plastics and wood materials, and the utility model can collect the drilled dist and ash in a cover for avoiding environmental pollution. The utility model is composed of a cover cap and a shell, the cover cap is fixed with a bump protection ring, and the shell is fixed with a brush. When used, the utility model can be sheathed on a drill bit, the bump protection ring is tightly stuck with a plane to be drilled, and the drill dust and ash can be brought in a hollow cavity of the utility model. The cover cap is transparent, when the hollow cavity is filled with dust and ash, users can directly pour out or open the cover cap for pouring out. The utility model has the advantages of simple structure, small size, light weight and convenient operation, and the brush at the inlet end of the shell can prevent the dust and ash from leaking out so as to avoid environment pollution.
Description
The utility model relates to a kind of dust cover of auxiliary, add-on parts electric impact drill of electric impact drill, when the suitable especially electric impact drill family room that supporting use and new clothes are fixed during boring on wall or on the aluminium alloys, plastics, wood materials, office, shop etc. are used for hanging, hang the article punching on the wall so that dirt, the bits that get out are collected in and avoid environment pollution in the cover.
Patent No. 92218576.X " dust collector of impact electric drill " a kind of dust collect plant that is enclosed within on the electric impact drill just is provided, need during use the brake bar on the dust collect plant is fixed on better use on the electric impact drill, therefore use is convenient not enough, volume is also big.
The purpose of this utility model is to provide a kind of dust cover of simple in structure, electric impact drill that volume is little, in light weight, easy to use.
The utility model is achieved in that the dust cover of electric impact drill is made up of cover cap and housing, and is fixed with bump protection ring on the cover cap, is fixed with hairbrush on the housing.
Fig. 1. structural representation of the present utility model.
Fig. 2. the vertical view of Fig. 1.
Fig. 3. the upward view of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Cover cap (5) is made pot lid shape by transparent plastics, there is seam the marginal portion, the boss platform that through hole is arranged in the middle of the top has, the diameter of through hole and employed drill bit size are complementary, there are uniform four brace rods (4) neighboring of boss platform, there are uniform four reference columns (3) on the inner surface apertures limit of boss platform, and the position of reference column (3) is corresponding with brace rod (4), pastes the annular bump protection ring of being made by elastomeric material (2) on the boss table top.
The disc of housing (8) for being complementary with cover cap (5), there is the taper type of protrusion the centre, and a cylindrical cavity is arranged above the taper type, and the cavity upper end open cooperates with four reference columns (3) on the cover cap (5), and the centre, lower end has through hole and drill bit size to be complementary.
Hairbrush (1) is a fasten bristles in the steel wire of two buttons strands, and has the two-layer spiral coil of through hole, hairbrush (1) to be close in the cylindrical cavity on housing (6) taper type in the middle of will its coiled.
To be connected with the housing (6) of the seam on it with the cover cap (5) of bump protection ring (2), and make four reference columns (3) push down the integrant dust cover of hairbrush (1) with band hairbrush (1).
During use the bump protection ring (2) of this dust cover is close to the wall of being holed, the through hole that the drill bit of electric drill is held from housing (6) passes hairbrush (1) and enters cover cap (5) and drilled wall again, at this moment ash, sand under boring are brought in the cavity of dust cover by the brill stem portion of drill bit, when dirt, the bits of the inside are taken down dust cover after filling from drill bit, dirt, bits are directly poured out from the through hole at cover cap (5) top, fallen and can continue and used.If dirt, bits when being difficult for pouring out, only need to open cover cap (5) and take away from the stop portion of cover cap (5), just dirt, bits can be poured out, open and close convenience.
The utility model compared with prior art, this dust cover forms its knot by cover cap and housing two parts Structure is simple, volume is little, in light weight. And cover cap (5) is transparent, and the dirt of the inside, bits all see clearly, After filling cavity, just it can be poured out. Also only need during use dust cover is enclosed within on the drill bit, not the time spent Just take down, do not need other fixture, therefore use is also very convenient, has again hairbrush (1) to stop at housing (6) thus entrance point make dirt, bits be difficult for spilling to avoid environmental pollution.
