Abstract

The utility model relates to a dust collective sleeve of an electrodrill, which is arranged on the front half part of a drill head; the lower part of a sleeve body is provided with a sleeve seat; the inner wall of the sleeve body is provided with a lining pressing spring; a seat body in the sleeve seat is tightly clamped on a bearing. The dust collective sleeve of electrodrill is particularly suitable for matching use of an impact electrodrill and is particularly required in the upholstery and the building industry that the drilling is carried out on the operator's head top part, causing the pollution of the dust fall. The utility model has the advantages of convenient dust collection and soil removal, no affection for working, etc., is good for health and is a novelty dust-proof device with lower price and good effect.

Description

The electric drill Dust collective sleeve

The utility model relates to a kind of dust exhaust apparatus, is particularly suitable for and the supporting use of electric impact drill the need that prevent dust during the punching of portion's operation overhead.

The furred ceiling of decoration trade often has the operation in the punching of operator's head term portion, and cement or wooden drilling cuttings are gone into nose, the eye that falls, drill neck, spill the back of the body, make the operator be difficult to bear, and be also totally unfavorable to health.Labour protection problem in this has seemed the corner that passes into silence into, does not see the report that relevant dust arrester is arranged always.Reluctantly, the operator often keeps away it to wear bamboo hat, and dust is gone into nose, the hardship of the eye that falls though can alleviate, but looks because of holding high, and brings retaining sight line, unhandy drawback.

The purpose of this utility model is to manage to solve the dust pollution question that the bore operation labour protection of crown portion does not arouse attention as yet, and designs a kind of unlikely unrestrained human body of dust that gathers, and does not keep off the electric drill Dust collective sleeve of sight line again.

The purpose of this utility model can realize by following measure: whole cover is installed in the first half of drill bit, but the body of axial stretching is the garden tubular, and the body bottom is the block set that centre bore is arranged.

The utility model also can give perfect, body inwall by following measure and be lined with the lining stage clip; Block set is by the class bowl-type pedestal of top and the bearing be combined into of its below chucking; The end Zhou Youyi circle lining stage clip draw-in groove of class bowl-type pedestal.

Accompanying drawing is the utility model structural representation.

The utility model is described in detail below in conjunction with embodiment: body 2 skins can be made into the garden tubular with fine groove cloth, the pedestal 4 in the block set can the metal punching out or method such as plastics compacting make, make recessed class bowl-type of mesopore week.Centre bore is in order to logical drill bit 1, and its aperture is a bit larger tham the diameter of drill bit 1, with drill-pipe-sticking-head wall neither again little the falling in slit to the dust difficulty be principle, on every side one enclose draw-in groove 5 usefulness that groove is made lining stage clip 3.Bearing 6 is combined closely with pedestal 4 bottoms, the center bore of bearing 6 and drill bit 1 external diameter are almost equal, and both also should have more closely and cooperate, total requirement is drill bit 1 rotation, and the skin of the overcoat of bearing 6, pedestal 4, body 2 and lining stage clip 3 all are unlikely to be driven by drill bit 1 and change.

Also having a kind of more easy facture is that body 2 is adopted and thickness and suitable rubber or the plastic production of elasticity, do not want lining stage clip 3 in it, even the class bowl-type pedestal 4 of bottom is not wanted a bearing 6 with a good airproof performance yet.Though this is simple in structure, easy to make, rubber or plastic sheath are all easily aging.Do not have pedestal, allow bearing 6 hold concurrently and carry on a shoulder pole the duty of poly-dirt, even sealing also has by the worry of dust jam, through on probation, this is a very unwise move, and is worth choosing.

When the utility model uses, earlier this cover is inserted in the first half of drill bit from drill bit 1 rear cover, apex point is referred to the position of holing on the operator top, start rig, drill bit creeps into toward the depths, contracts in body 2 skins and lining stage clip 3 are all axial, but still be close to by drilling area, cover around the boring, dust falls in the body 2 and on the block set, bores complete dust of toppling in it and get final product.

The utility model can effectively protect the operator of top bore operation to avoid dust pollution, does not influence vision and operation, and is convenient and healthy.
