Abstract
The utility model relates to a dustproof cover for an electric hammer. The electric hammer is a class of electric drill and is mainly used for drilling on concrete, brick walls, stones and so on. When the electric hammer drills on the top, fallen dust can influence the sanitation and the health of an operator. The dustproof cover for the electric hammer consists of a front cover body, an internal lining ring and a rear cover body, and is characterized in that the front cover body is a threaded or corrugated telescopic tube which is telescopic under stress and can not be automatically rebounded; the internal lining ring is made of duroplasts and can be closely arranged on the lower part of the front cover body; the rear cover body takes the shape of an inversed bottle cover and made of rubber, and the middle of the rear cover body is thick and provided with a small hole; the rear cover body tightly covers the lower part of the front cover body; and the internal lining ring is supported on a combined part of the front cover body and the rear cover body so as to prevent the lower part of the front cover body from being deformed and fallen off. The small hole of the dustproof cover is sleeved on the tail of a drill bit before drilling and the front cover body is withdrawn, thereby the dust is fallen into the cover while drilling. The dustproof cover for the electric hammer is economic and practical and provides convenience for thousands upon thousands of electric hammer users.
Description
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, but there is not 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 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, simple to operate, easy to carry to people, highly versatile, cheap electric hammer dust cover.
The utility model is by preceding cover body, and interior lining ring and rear cover body are formed, and it is characterized in that: preceding cover body is screw-like or corrugated telescoping tube, and is made of plastic, 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.Interior lining ring is made with duroplasts, and the circle wall is screw-like or corrugated, and diameter is more bigger or smaller than preceding cover body telescoping tube, the bottom of cover body telescoping tube before can snugly fitting into.Rear cover body is for being inverted the bottle cap shape, and there is an aperture at thicker center, centre, makes with rubber, can tightly be enclosed within the drill bit root.The bottom of cover body before the rear cover body inboard tightly encases, interior lining ring support be in the joint portion of preceding cover body and rear cover body, and paste with gelatin substance, when preventing to use before the cover body lower deformation come off.
When hole in the top, the dust under the utility model can be avoided boring flies upward everywhere with electric hammer, and the health that is of value to the operator is with healthy.The electric hammer drill root has only two kinds of models at present, so the aperture in the middle of the rear cover body only need be made two kinds of models, therefore promptly applicable various electric hammers have splendid versatility.
The utility model effect is remarkable, and is simple to operate, easy to carry, and highly versatile is 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 drawings and Examples the utility model is further specified.
Fig. 1 is the utility model vertical section structure schematic diagram;
Fig. 2 is the utility model user mode figure.
The utility model is by front cover body 1, and interior lining ring 2 (thick lines part) and rear cover body 3 (dash area) form, front cover body 1 is screw-like or corrugated telescoping tube, made of plastic; Interior lining ring 2 usefulness duroplasts are made, and the circle wall is screw-like or corrugated; Rear cover body 3 is made with rubber for being inverted the bottle cap shape, and there is an aperture 4 at thicker center, centre, can tightly be enclosed within the drill bit root; After Cover body 3 inboards tightly encase the bottom of front cover body, and 2 supports of interior lining ring are in the joint portion of front cover body and rear cover body, when preventing from using before The cover body lower deformation comes off.
The specific embodiment
(referring to Fig. 1--2), before the boring of top, 4 places tightly are enclosed within the drill bit root with the dust cover aperture, then preceding cover body 1 are drawn back from the top, during boring, dust cover and drill bit rotate together, along with drill bit deeply, preceding cover body 1 is met the top and is easily shunk, dust just drops in the cover.
