A kind of dust-proof cover for electric drill
Technical field
The utility model relates to a kind of dust arrester, specifically a kind of dust cover for electric hand drill.
Background technology
Electric drill is a kind of instrument holed for metal material, timber, plastics etc..Electric hand drill is widely used in building, finishing, furniture etc. industry, for perforate on object or pierce object.
When holing with electric hand drill, producing substantial amounts of dust, particularly in plastic or other material, during boring, the health of operator can be produced harm greatly by produced dust, and substantial amounts of dust flies away and also can the environment of surrounding be impacted in atmosphere.In order to eliminate the impact of dust, special dust suction ventilation unit can be set in a large amount of Factory Buildings using electric drill.This dust suction ventilation unit not only cost is high but also uses and inconvenient.
Electric hand drill great majority are operated with by individual operator, and place to use is not fixed.Common dust suction ventilation unit is not particularly suited for the dust-proof dust-removing of electric hand drill.
Summary of the invention
The purpose of this utility model is in that to provide a kind of simple in construction, the dust-proof cover for electric drill of easy to use and flexible.
The purpose of this utility model is achieved in that the corrugated cover cylinder including being made up of elastomeric material, the front end of cover cylinder is at the bottom of the cylinder uncovered, rear end is with central aperture, and the tapping in the middle of at the bottom of described cylinder is with the internal diameter fixed cover equal with electric drill housing forward end external diameter.
This utility model can also include:
1, fixation clamp is set outside fixed cover.
2, cover cylinder front end is uncovered in horn-like.
3, arranging dust-exhausting port at the bottom of cylinder, dust-exhausting port connects dust conveying pipe, dust conveying pipe is connected with dust collection box.
This utility model designs according to construction features and the use environment of electric hand drill.The front end of cover barrel cover of the present utility model is outer at the drill bit of electric drill, fixed cover set electric drill housing during use, produced when row bore operation is crept in electricity consumption broken cuts, powder, dust etc. are blocked in cover cylinder, will not produce to splash, be scattered.The boring dust impact on surrounding enviroment can be effectively prevented, enable in particular to prevent boring dust from electric drill operator being damaged.This utility model is directly anchored to the front end of electric drill housing, and its installation and removal can be synchronously performed with the assembling of drill bit or replacing, and installation and removal are quite convenient to.
Cover cylinder is constituted wave structure by elastomeric material, and its length is freely adjustable, it is possible to pierces the change of the degree of depth along with drill bit and changes, without influence on the normal use of electric drill.The front end of the corrugated cover cylinder being made up of elastomeric material is close to the surface of drilled material under the effect of elastic force, has the effect that nature seals, can be effectively prevented the splashing of dust.
Generally, device of the present utility model need not any auxiliary power.This utility model is by simple structure, can effectively powder produced when holing with electric drill, dust be blocked in cover cylinder, it is possible not only to eliminate the dust pollution to environment, powder also can be prevented to splash and cause personal injury, but also be conducive to the recovery of powder.This utility model has simple in construction, advantage with low cost, easy to use concurrently, is particularly well-suited to electric hand drill.

Fig. 2 is the schematic diagram of the structure of the first embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing citing, this utility model is described in more detail.
In conjunction with Fig. 1, the composition of the first embodiment of the present utility model includes the corrugated cover cylinder 2 being made up of elastomeric material, the front end of cover cylinder is at the bottom of the cylinder uncovered, rear end is with central aperture, and the tapping in the middle of at the bottom of described cylinder is with the internal diameter fixed cover equal with electric drill housing forward end external diameter.During use, the front end of cover barrel cover is outer at the drill bit 1 of electric hand drill 4, fixed cover set electric drill housing, can realize the installation between dust cover and electric drill with fixing.
Fixing more firm in order to what make between dust cover and electric hand drill, it is possible to fixation clamp 3 to be set outside fixed cover, by fixation clamp, dust cover is fastened on electric drill housing forward end.
In order to make dust cover contact well with drilled surface, reach better dust-proof effect, the open design of cover cylinder front end can be become horn-like.
The second embodiment of the present utility model is on the basis of the first embodiment, arranges dust-exhausting port at the bottom of at cylinder, and dust-exhausting port connects dust conveying pipe 5, and the other end of dust conveying pipe connects dust collection box.Dust collection box can be provided with the casing of dust suction and defecator.This embodiment is more suitable for that boring amount is big, need the place worked continuously for a long time.
