Abstract

An electric hammer that belongs to the electric drill is mainly used for boring a hole on the concrete, the brick wall, the stone and the like. When the worker utilizes the prior electric hammer to bore a hole overhead, the falling dust can be harmful to the sanitation and the health of the operator. The utility model relates to an electric hammer dustproof hood, which consists of an outer hood, an inner hood and a telescopic pipe, and is characterized in that the outer hood is of a hollow cuboid, and the bottom of the outer hood is provided with four claws that are movable and are convenient to be assembled to or disassembled from the electric hammer; the inner hood is of a barrel shape, and the bottom is projected, and the center of the inner hood is provided with a hood hole, and the hood hole is slightly larger than the root part of the drill bit; the telescopic pipe is of a spiral shape or a corrugation shape, and the telescopic pipe can be stressed to extend and withdraw, but is free from being automatically bounced up. The inner hood is blocked inside the outer hood and is fixed by a screw, and an upper blocking port of the inner hood is blocked inside a lower port of the telescopic pipe and is also fixed by a screw. The inner hood and the telescopic pipe can be integrally formed. Before boring a hole overhead, the dustproof hood can be sleeved on the head part of the electric hammer, and the telescopic pipe is stretched, so that the dust can fall into the dustproof hood when boring the hole. The dustproof hood is economic and practical, and can bring about convenience to the users.

Description

The electric hammer dust cover

Technical field

Electric hammer is a classification in the electric drill, is mainly used to boring on concrete, brick wall, stone material etc.The utility model relates to a kind of electric hammer auxiliary equipment, and definite says so a kind of and the matching used dust cover of electric hammer.

Background technology

Electric hammer is an instrument commonly used in building and the decorative engineering.The workman, can not make the dust under boring fly upward everywhere if there is dust guard to return, thereby not only hinder operation when hole in the top with it, and diminishes operator's health and health.1932, company of German Bosch released the first in the world platform electric hammer, yet since electric hammer comes out, has not occurred a kind of economical and practical electric hammer dust guard on the market always.There is a kind of dust exhaust apparatus (data is from Bosch electric hammer specification) that connects domestic vacuum cleaners and electric hammer in Bosch, and effect should be good, but do not have service condition mostly in developing country; Though popularize at developed country's dust catcher, economical and practical easy to carry aspect shortcoming to some extent again.Common electric hammer dust cover is to be inverted the bottle cap shape on the Chinese market at present, makes with black rubber, though it is cheap, dustproof effect is too poor.

Summary of the invention

The purpose of this utility model is to provide a kind of effect remarkable to people, simple to operate, easy to carry, cheap electric hammer dust cover, it is made up of outer cover, inner cover and telescoping tube, is characterised in that: outer cover is hollow tetragonal body, and its four seamed edges are slope, slope only one little section on top links to each other with main body, and remainder is the space; The outer cover bottom is four claws that the cavity is arranged, and links to each other with four interareas of outer cover respectively; Inner cover is a tubbiness, and the bottom raises up, and there is a cover hole at the center, and the aperture is more bigger than drill bit root; Telescoping tube is screw-like or corrugated, and this manages stressed scalable, but can not rebound automatically, and the smoke exhaust ventilator smoke exhaust pipe of its characteristic and family expenses is identical.Inner cover is stuck in the outer cover, fixes with screw, and inner cover is suitable for reading to be stuck in the telescoping tube end opening, also fixes with screw.Inner cover and telescoping tube also integral body make.

Before the boring of top, insert drill bit with electric hammer earlier, will prevent dust covers in place, central cover hole from drill bit upper end cover down, again finger is inserted in outer cover seamed edge gap, four claws in outer cover bottom is strutted can be enclosed within the electric hammer head.If drill bit is thicker than the cover hole, can packages cover earlier and insert drill bit again.Telescoping tube is drawn back and can hole, and about 90% dust drops in the cover during boring, small amount of dust from the claw of bottom surface the cavity and the gap on claw limit spill, dust infiltrates the electric hammer head when preventing down ash.

Dust cover uses only for import and imitative import electric hammer, and the drill bit root of such electric hammer is cylindrical.When hole in the top, the dust under the utility model can be avoided boring flies upward useful operator's eyes, respiratory system, personal hygiene and surrounding enviroment everywhere with electric hammer.Though versatility is not good enough, with the drill bit rotation, visual effect is not better for it, and is especially convenient and practical when the boring of place, corner.

The utility model effect is remarkable, and is simple to operate, easy to carry, cheap, and the health that is of value to the operator will bring glad tidings for the user of the whole world thousands upon thousands electric hammer user, especially developing countries with healthy.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 is dust cover user mode figure;

Fig. 2 is dust cover shroud floor figure;

Fig. 3 is a dust cover vertical section structure schematic diagram.

This dust cover is by outer cover 1, inner cover 3, and telescoping tube 4 forms, and four seamed edges of outer cover have space 2, and the outer cover bottom surface has four Mobilizable claw 5 has cavity 6 on the claw, cover hole 7 is arranged in the middle of the inner cover 3, telescoping tube and inner cover, and inner cover and outer cover, All be fixed together with screw 8.

The specific embodiment

(referring to Fig. 1--3), before the boring of top, insert drill bit with electric hammer earlier, will prevent dust covers in 7 places, central cover hole from drill bit upper end cover down, again finger is inserted in 2 places, outer cover seamed edge space, and four claws 5 in outer cover 1 bottom are strutted, can be with the enclosure at the electric hammer head.If drill bit is thicker than cover hole 7, can packages cover earlier and insert drill bit again.Telescoping tube 4 is drawn back and can hole, and about 90% dust drops in the cover during boring, small amount of dust from the claw of bottom surface cavity 6 and the space 2 on claw limit spill, dust infiltrates the electric hammer head when preventing down ash.After boring finished, dust was poured out in will covering earlier, outer cover bottom claw is strutted can take off dust cover again.

Claims

1. electric hammer dust cover, form by outer cover, inner cover, telescoping tube, it is characterized in that: outer cover is hollow tetragonal body, and there are four mobilizable claws the bottom surface, and inner cover is a tubbiness, bottom protrusion, there is a cover hole at the center, and telescoping tube is screw-like or corrugated hollow pipe, and this manages stressed scalable, but can not rebound automatically, inner cover and telescoping tube also integral body make.

2. according to the described electric hammer dust cover of claim 1, it is characterized in that: four seamed edges of outer cover are slope, and slope only one little section on top links to each other with main body, and all the other are the space.
