Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] Such as Figure 1 to Figure 3 As shown, a kind of percussion drill drilling dustproof cover in this specific embodiment comprises a fixed ring sleeve 1 and a telescopic ring sleeve 2 that are separated and arranged on the same centerline, and the inner diameter of the fixed ring sleeve 1 and the inner diameter of the telescopic ring sleeve 2 Consistent, the inner hole of the fixed ring sleeve 1 is installed with a fastening rubber sleeve that is concentric with the center line. One end of 2 gradually decreases towards the end of the telescopic ring sleeve 2, and the fixed ring sleeve 1 can be fixed on the head of the percussion drill to be used by fastening the rubber sleeve, and the fixed ring sleeve 1 and the telescopic ring sleeve 2 are wound A plurality of guide sliders 3 are evenly spaced on the centerline of the sleeve 1, the axis direction of t...

The invention discloses a drilling dustproof sleeve for a percussion drill. The drilling dustproof sleeve comprises a fixed ring sleeve and a telescopic ring sleeve; the fixed ring sleeve is internally provided with a fastening rubber sleeve of which an inner hole is variable in diameter, and the fixed ring sleeve is used for sleeving the head of a to-be-used percussion drill for fixing; a telescopic corrugated pipe is arranged between and fixedly connected with the fixed ring sleeve and the telescopic ring sleeve; a plurality of guide sliding rods are further arranged between the fixed ring sleeve and the telescopic ring sleeve, the two ends of the guide sliding rods penetrate through the fixed ring sleeve and the telescopic ring sleeve, limiting heads are fixed to the two ends of the guide sliding rods for limiting, the guide sliding rods are sleeved with springs so that the limiting heads can abut against the fixed ring sleeve and the telescopic ring sleeve, and meanwhile, the telescopic corrugated pipe can be in the elongation state. The drilling dustproof sleeve is simple in structure, convenient to use and capable of being adjusted along with drilling of a drilled hole, and influence of drilling dust on the surrounding environment is avoided.
Description
technical field [0001] The invention relates to a dustproof device, in particular to a percussion drill drilling dustproof cover. Background technique [0002] In various engineering constructions such as home improvement projects, hand-held impact drills are usually used to drill holes on buildings. However, a large amount of dust and particles will be generated during the use of the impact drill, causing indoor air pollution, which will not only affect the operator's drilling sight, but also damage the health of the operator if he is in the dust environment for a long time. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide a hammer drill drilling dust cover that can avoid dust generation during the drilling process of the hammer drill. [0004] In order to solve the problems of the technologies described above, the present invention adopts the fol...
